Some services are specified as essential to enable operation of an internationalpaging system. A number of optional services are also described, which operators may include in theirsystems.The security aspects of the system are also included in this clause.4.1.2Framework for describing the servicesThe text associated with each service is structured in the following way:DefinitionThis paragraph provides a general definition and description of the service as it is seen by the user.Procedures-provision:-This paragraph indicates if the service should be essential or optional for the networkoperators of the ERMES system.-normal procedures:-This paragraph gives an indication of who (calling party, fixed or mobile subscriber) issupposed to activate the service and on what conditions it is made available to the users(e.g. per call basis or by registration).Network capabilities for chargingThis paragraph gives an indication of what charging arrangements the system shall be able to support.Interworking requirementsThis paragraph describes the interworking requirements between the different ERMES networks in orderto implement a service.SIST ETS 300 133-2:1999
Page 11ETS 300 133-2: November 1997Interaction with other servicesThis paragraph describes the interactions with other ERMES services when the service being described isactivated.4.1.3Essential and optional servicesEach service shall be considered as essential or optional for the network operator. In table A.1, theessential and optional supplementary services and facilities for each paging category is given.4.2Basic servicesThe system shall offer mobile subscribers levels of basic paging services according to the receivercapabilities. The system shall check that paging calls are not accepted to higher levels than the onecorresponding to the subscription. This check shall also take place on activation of a supplementaryservice, e.g. diversion of traffic.The ERMES system provides two kinds of call in each basic service:-individual calls that are initiated by using one Address Code (AdC) and are intended for only onemobile subscriber;-group calls that are initiated by using one Group Address Code (GAdC) and are intended for two ormore mobile subscribers.4.2.1Tone-only pagingDefinitionTone-only paging is the first basic service level and simplest kind of paging service, corresponding to thetraditional type of radio paging. The tone-only service means that paging signals to a particular receivershall cause the receiver to generate a simple alert signal. The system shall support up to 8 different alertsignals per Radio Identity Code (RIC). The system shall transmit the message within a message deliverytime depending on the level of priority (see subclause 6.2).Procedures-provision:-This essential service shall be provided by all network operators. It shall be implemented inthe Paging Network Controller (PNC) and all types of receivers, except transparent datareceivers. The service may be implemented in the transparent data receiver.-normal procedures:-Tone-only paging can be activated by the calling party by any Public Switched TelephoneNetwork (PSTN) telephone on a per call basis to a mobile subscriber in the system. It mayalso be activated by other terminal equipment.Network capabilities for chargingThe service should be charged on subscription and/or on a per call basis according to the networkoperator's policy.Interworking requirementsNone.Interaction with other servicesA number of supplementary services can not be activated when tone-only calls are sent (see table A.1).SIST ETS 300 133-2:1999
Page 12ETS 300 133-2: November 19974.2.2Numeric pagingDefinitionNumeric paging is the second service level. It allows transmission of up to at least 20 numeric or specialcharacters. This service is intended for mobile subscribers using pagers with the capability to receive,store and display numeric information in addition to tone-only paging. The character set is included intable B.1. The system shall transmit the message within a message delivery time depending on the levelof priority (see subclause 6.2). The maximum message length that the ERMES system can support is16 000 numeric characters. The network operators shall provide for a maximum message length between20 and 16 000 numeric characters. Messages longer than the maximum message length that a specificreceiver can accept shall not be delivered. The calling party shall be informed that the message is toolong (see also subclause 4.2.4 for very long messages).Procedures-provision:-This essential service shall be provided by all network operators. It shall be implemented inthe PNC as well as in numeric and alphanumeric receivers. The service may be implementedin the transparent data receiver.-normal procedures:-The service can be activated by the calling party on a per call basis to a mobile subscriber inthe system.Network capabilities for chargingThe service should be charged on subscription and/or on a per call basis according to the networkoperator's policy.Interworking requirementsNone.Interaction with other servicesNone.4.2.3Alphanumeric pagingDefinitionAlphanumeric paging is the third service level. It allows transmission of text information with up to at least400 alphanumeric characters. This service is for mobile subscribers using receivers with the capability toreceive, store and display text information in addition to tone-only and numeric paging. The basiccharacter set is defined in table B.3. The system shall transmit the message within a message deliverytime depending on the level of priority (see subclause 6.2). The maximum message length that theERMES system can support is 9 000 alphanumeric characters. The network operators shall provide for amaximum message length between 400 and 9 000 alphanumeric characters. Messages longer than themaximum message length that a specific receiver can accept shall not be delivered. The calling party shallbe informed that the message is too long (see also subclause 4.2.4 for very long messages).Procedures-provision:-This essential service shall be provided by all network operators. It shall be implemented inthe PNC and in alphanumeric receivers. The service may be implemented in the transparentdata receiver.SIST ETS 300 133-2:1999

Thesystem shall transmit the message within a message delivery time depending on the level ofpriority (see subclause 6.2). The use of the data stream is determined by the application chosen by thesubscriber. Only the part of the radio channel dedicated to the message allows a full bit transparency. Themaximum message length that the ERMES system can support is 64 kbits. The network operators mayprovide for a maximum message length of less than 64 kbits. Messages longer than the maximummessage length that a specific receiver can accept shall not be delivered. The calling party shall beinformed that the message is too long.Very long messages (longer than the defined maximum) can be sent through the ERMES system only ifthey are split into messages shorter than the maximum length. Users who wish to send such messages,may define a method of linking the parts of the messages together, between calling party and receiver.This method shall be transparent to the ERMES system, i.e. the parts shall be transmitted as separatemessages.Procedures-provision:-Provision of this service shall be optional for the network operators. Restrictions on themessage length can be imposed by the network operator according to his policy. It shall beimplemented in the PNC as well as in the receiver. Lower categories may be implemented inthe transparent data receiver.-normal procedures:-The service can be activated by the calling party on a per call basis to a mobile subscriber inthe system.Network capabilities for chargingThe service should be charged on subscription and/or on a per call basis according to the networkoperator's policy.Interworking requirementsNone.SIST ETS 300 133-2:1999

The offered supplementary servicesmay be used by the subscribers/users at their discretion.4.3.1Call related supplementary services4.3.1.1Acknowledgements4.3.1.1.1Valid input acknowledgementsDefinitionDuring the input of a call, acknowledgements shall be generated by the system to the calling partyindicating the call status. At least the following three types of acknowledgements shall be provided:a)call accepted acknowledgement:-The called AdC (individual or GAdC) is (is not) valid and the system is (is not) ready to acceptthe call. The calling party is invited to enter data referring to additional information or therequired supplementary service(s) or to enter the message.-A call shall be treated as unconditionally accepted when the home operator is able toguarantee a network status better than a threshold C in the areas in which the page isdestined for transmission (for the calculation of network status see ETS 300 133-3 [2]).-A call shall be treated as partially accepted when the network operator is only able toguarantee a network status between a threshold UC and a threshold C in the areas in whichthe page is destined for transmission.-The call shall be rejected when the network operator cannot guarantee a network statusgreater than a threshold UC in the areas in which the page is destined for transmission.-Each network operator shall define its own thresholds C and UC, which can be identical ifonly two call acceptance conditions are to be given to the calling party.b)supplementary service acknowledgement:-The supplementary service required is (is not) valid. The calling party is invited to enter datareferring to additional supplementary services or to enter the message.c)page accepted acknowledgement:-The message is (is not) valid.

Roaming shall beactivated by the subscriber after authentication. Activation shall be for a specific period oftime. It can be de-activated either automatically by the PNC when activation time has expiredor by the subscriber (after authentication) before the activation time has expired. The servicecan be activated/de-activated through the home PNC or a visited PNC. In the case thatservice area and roaming area are adjacent or overlapping the calls shall be transmitted inboth areas. According to the network operator's policy the calls may also be transmitted toboth areas even if they are not adjacent. A test call may automatically be generated by thesystem immediately after the start time of roaming, to confirm to the mobile subscriber thatroaming has been activated successfully.Network capabilities for chargingAccording to the policy of the network operator. Inter-operator charging for this feature shall be accordingto inter-operator agreements.Interworking requirementsSee subclauses 4.3.1.1.1 and 4.3.1.1.2.Interaction with other servicesWhen the subscriber is roaming to another network it shall be impossible to use priority 1 service. Level 3priority and urgent message indication can only be activated if the visited networks offer these services.Activation of diversion of traffic or temporary barring shall suspend provision of the roaming service.4.3.1.2.2Diversion of trafficDefinitionThe facility of a mobile subscriber to have his calls diverted to another receiver registered in the samenetwork, or in another network within the ERMES system, or to another telecommunication system for aperiod of time. Diversion can be made only to individual AdCs provided that the AdC is not alreadydiverted. If the divert recipient wishes to activate diversion for his own AdC, he shall be warned thatsuspension of the already activated diversion of calls to his AdC shall occur. During this period the calls tothe originally diverted AdC shall be rejected (see ETS 300 133-3 [2], subclause 7.2).Procedures-provision:-Provision of this service shall be optional for the network operators. Diversion outside homenetwork can only be provided if there is an agreement between the network operators and/orthe operators of other systems involved.-normal procedures:-The service should be made available to mobile subscribers on a registration basis or ondemand, according to the network operator's policy. Diversion shall be activated by thesubscriber after authentication. Activation shall be for a specific period of time. It can be de-activated either automatically by the PNC when activation time has expired or by thesubscriber (after authentication) before the activation time expires.SIST ETS 300 133-2:1999

Inter-operator charging for this feature shall be according to inter-operator agreements.Interworking requirementsNone.Interaction with other servicesA check shall be made to avoid diversion to AdCs having lower categories of subscriptions. Only thosesupplementary services supported by the divert recipient's Home PNC (PNC-H) and the divert recipient'sreceiver can be provided during the period of diversion. The mobile subscriber can not activate anysupplementary service, except temporary barring, after activation of diversion of traffic. Request fordiversion to another AdC shall suspend the previous divert request. The supplementary services that themobile subscriber has already activated shall be suspended.Activation for a group using common RIC affects the whole group. In the case of Closed User Groups(CUGs) it shall be possible to divert the call only within the CUG.The diverted messages shall follow the message numbering of the divert recipient.Calls shall be accepted and processed even if the divert recipient does not have all the supplementaryservices of the subscriber who has activated the service. The calling party shall not be informed that thesesupplementary services are not supported by the divert recipient.4.3.1.2.3Choice of destinationDefinitionA service to give the calling party the facility to choose the geographical areas that he wants the call to betransmitted in. The calling party has the following alternatives:-transmission according to the mobile subscriber location register;-transmission in one or more areas in addition to the location register.Procedures-provision:-Provision of this service shall be optional for the network operators. Subject to the policy ofthe network operator, the service may have restrictions on the number of geographical areas.-normal procedures:-The service shall be provided to the calling party on a per call basis.Network capabilities for chargingAccording to the policy of the network operator.Interworking requirementsNone.SIST ETS 300 133-2:1999

4.1 General
4.1.1 Introduction
In this clause the set of basic and supplementary services that may be supported by an ERMES network
is defined and described. Some services are specified as essential to enable operation of an international
paging system. A number of optional services are also described, which operators may include in their
systems.
The security aspects of the system are also included in this clause.
4.1.2 Framework for describing the services
The text associated with each service is structured in the following way:
Definition
This paragraph provides a general definition and description of the service as it is seen by the user.
Procedures
- provision:
- This paragraph indicates if the service should be essential or optional for the network
operators of the ERMES system.
- normal procedures:
- This paragraph gives an indication of who (calling party, fixed or mobile subscriber) is
supposed to activate the service and on what conditions it is made available to the users
(e.g. per call basis or by registration).
Network capabilities for charging
This paragraph gives an indication of what charging arrangements the system shall be able to support.
Interworking requirements
This paragraph describes the interworking requirements between the different ERMES networks in order
to implement a service.
Page 11
ETS 300 133-2: November 1997
Interaction with other services
This paragraph describes the interactions with other ERMES services when the service being described is
activated.
4.1.3 Essential and optional services
Each service shall be considered as essential or optional for the network operator. In table A.1, the
essential and optional supplementary services and facilities for each paging category is given.
4.2 Basic services
The system shall offer mobile subscribers levels of basic paging services according to the receiver
capabilities. The system shall check that paging calls are not accepted to higher levels than the one
corresponding to the subscription. This check shall also take place on activation of a supplementary
service, e.g. diversion of traffic.
The ERMES system provides two kinds of call in each basic service:
- individual calls that are initiated by using one Address Code (AdC) and are intended for only one
mobile subscriber;
- group calls that are initiated by using one Group Address Code (GAdC) and are intended for two or
more mobile subscribers.
4.2.1 Tone-only paging
Definition
Tone-only paging is the first basic service level and simplest kind of paging service, corresponding to the
traditional type of radio paging. The tone-only service means that paging signals to a particular receiver
shall cause the receiver to generate a simple alert signal. The system shall support up to 8 different alert
signals per Radio Identity Code (RIC). The system shall transmit the message within a message delivery
time depending on the level of priority (see subclause 6.2).
Procedures
- provision:
- This essential service shall be provided by all network operators. It shall be implemented in
the Paging Network Controller (PNC) and all types of receivers, except transparent data
receivers. The service may be implemented in the transparent data receiver.
- normal procedures:
- Tone-only paging can be activated by the calling party by any Public Switched Telephone
Network (PSTN) telephone on a per call basis to a mobile subscriber in the system. It may
also be activated by other terminal equipment.
Network capabilities for charging
The service should be charged on subscription and/or on a per call basis according to the network
operator's policy.
Interworking requirements
None.
Interaction with other services
A number of supplementary services can not be activated when tone-only calls are sent (see table A.1).
Page 12
ETS 300 133-2: November 1997
4.2.2 Numeric paging
Definition
Numeric paging is the second service level. It allows transmission of up to at least 20 numeric or special
characters. This service is intended for mobile subscribers using pagers with the capability to receive,
store and display numeric information in addition to tone-only paging. The character set is included in
table B.1. The system shall transmit the message within a message delivery time depending on the level
of priority (see subclause 6.2). The maximum message length that the ERMES system can support is
16 000 numeric characters. The network operators shall provide for a maximum message length between
20 and 16 000 numeric characters. Messages longer than the maximum message length that a specific
receiver can accept shall not be delivered. The calling party shall be informed that the message is too
long (see also subclause 4.2.4 for very long messages).
Procedures
- provision:
- This essential service shall be provided by all network operators. It shall be implemented in
the PNC as well as in numeric and alphanumeric receivers. The service may be implemented
in the transparent data receiver.
- normal procedures:
- The service can be activated by the calling party on a per call basis to a mobile subscriber in
the system.
Network capabilities for charging
The service should be charged on subscription and/or on a per call basis according to the network
operator's policy.
Interworking requirements
None.
Interaction with other services
None.
4.2.3 Alphanumeric paging
Definition
Alphanumeric paging is the third service level. It allows transmission of text information with up to at least
400 alphanumeric characters. This service is for mobile subscribers using receivers with the capability to
receive, store and display text information in addition to tone-only and numeric paging. The basic
character set is defined in table B.3. The system shall transmit the message within a message delivery
time depending on the level of priority (see subclause 6.2). The maximum message length that the
ERMES system can support is 9 000 alphanumeric characters. The network operators shall provide for a
maximum message length between 400 and 9 000 alphanumeric characters. Messages longer than the
maximum message length that a specific receiver can accept shall not be delivered. The calling party shall
be informed that the message is too long (see also subclause 4.2.4 for very long messages).
Procedures
- provision:
- This essential service shall be provided by all network operators. It shall be implemented in
the PNC and in alphanumeric receivers. The service may be implemented in the transparent
data receiver.
Page 13
ETS 300 133-2: November 1997
- normal procedures:
- The service can be activated by the calling party on a per call basis to a mobile subscriber in
the system.
Network capabilities for charging
The service should be charged on subscription and/or on a per call basis according to the network
operator's policy.
Interworking requirements
None.
Interaction with other services
None.
4.2.4 Transparent data paging
Definition
Transparent data paging is a service allowing transmission of an arbitrary data stream to the receiver. The
system shall transmit the message within a message delivery time depending on the level of
priority (see subclause 6.2). The use of the data stream is determined by the application chosen by the
subscriber. Only the part of the radio channel dedicated to the message allows a full bit transparency. The
maximum message length that the ERMES system can support is 64 kbits. The network operators may
provide for a maximum message length of less than 64 kbits. Messages longer than the maximum
message length that a specific receiver can accept shall not be delivered. The calling party shall be
informed that the message is too long.
Very long messages (longer than the defined maximum) can be sent through the ERMES system only if
they are split into messages shorter than the maximum length. Users who wish to send such messages,
may define a method of linking the parts of the messages together, between calling party and receiver.
This method shall be transparent to the ERMES system, i.e. the parts shall be transmitted as separate
messages.
Procedures
- provision:
- Provision of this service shall be optional for the network operators. Restrictions on the
message length can be imposed by the network operator according to his policy. It shall be
implemented in the PNC as well as in the receiver. Lower categories may be implemented in
the transparent data receiver.
- normal procedures:
- The service can be activated by the calling party on a per call basis to a mobile subscriber in
the system.
Network capabilities for charging
The service should be charged on subscription and/or on a per call basis according to the network
operator's policy.
Interworking requirements
None.
Page 14
ETS 300 133-2: November 1997
Interaction with other services
The bureau service can not be activated when the transparent data service is used.
4.3 Supplementary services
A supplementary service modifies or supplements a basic service. The offered supplementary services
may be used by the subscribers/users at their discretion.
4.3.1 Call related supplementary services
4.3.1.1 Acknowledgements
4.3.1.1.1 Valid input acknowledgements
Definition
During the input of a call, acknowledgements shall be generated by the system to the calling party
indicating the call status. At least the following three types of acknowledgements shall be provided:
a) call accepted acknowledgement:
- The called AdC (individual or GAdC) is (is not) valid and the system is (is not) ready to accept
the call. The calling party is invited to enter data referring to additional information or the
required supplementary service(s) or to enter the message.
- A call shall be treated as unconditionally accepted when the home operator is able to
guarantee a network status better than a threshold C in the areas in which the page is
destined for transmission (for the calculation of network status see ETS 300 133-3 [2]).
- A call shall be treated as partially accepted when the network operator is only able to
guarantee a network status between a threshold UC and a threshold C in the areas in which
the page is destined for transmission.
- The call shall be rejected when the network operator cannot guarantee a network status
greater than a threshold UC in the areas in which the page is destined for transmission.
- Each network operator shall define its own thresholds C and UC, which can be identical if
only two call acceptance conditions are to be given to the calling party.
b) supplementary service acknowledgement:
- The supplementary service required is (is not) valid. The calling party is invited to enter data
referring to additional supplementary services or to enter the message.
c) page accepted acknowledgement:
- The message is (is not) valid. The call shall (shall not) be transmitted.
Procedures
- provision:
- This essential service shall be provided by all network operators.
- normal procedures:
- The service shall apply to all calls. Restrictions due to the access method used are described
in ETS 300 133-3 [2].

whether or not a feature, such as a supplementary service control operation, has been successfully
completed.
Procedures
- provision:
- This essential service shall be offered by all network operators for the subscriber features
provided. An all feature reset facility should be provided.
- normal procedures:
- The service shall apply to all features accessible to the subscriber. Service to the fixed
subscriber can only be provided in the subscribed network. Restrictions due to the access
method used are described in ETS 300 133-3 [2].
Network capabilities for charging
There shall be no charging for this service.
Interworking requirements
In the case of a roaming subscriber and/or if diversion of traffic outside home network is activated, the
PNC shall be informed if the service is offered by the transmitting network.
Interaction with other services
None.
4.3.1.2 Supplementary services related to the destination of the call
4.3.1.2.1 Roaming service
Definition
Roaming is the service which enables the mobile subscriber to choose, for a specific period, in which
country(ies) and geographical area(s), outside his service area, he wants his calls transmitted. The
subscriber can also roam within his home network. If the requested area is served by several operators
the choice of network is according to inter-operator agreements, influenced by tariffs, supplementary
services, etc. The mobile subscriber shall have the capability to define the duration of roaming.
Page 16
ETS 300 133-2: November 1997
Procedures
- provision:
- This essential service shall be provided by all network operators.
- normal procedures:
- The service shall be made available to the mobile subscriber on demand. Roaming shall be
activated by the subscriber after authentication. Activation shall be for a specific period of
time. It can be de-activated either automatically by the PNC when activation time has expired
or by the subscriber (after authentication) before the activation time has expired. The service
can be activated/de-activated through the home PNC or a visited PNC. In the case that
service area and roaming area are adjacent or overlapping the calls shall be transmitted in
both areas. According to the network operator's policy the calls may also be transmitted to
both areas even if they are not adjacent. A test call may automatically be generated by the
system immediately after the start time of roaming, to confirm to the mobile subscriber that

4.3.1.2.2 Diversion of traffic
Definition
The facility of a mobile subscriber to have his calls diverted to another receiver registered in the same
network, or in another network within the ERMES system, or to another telecommunication system for a
period of time. Diversion can be made only to individual AdCs provided that the AdC is not already
diverted. If the divert recipient wishes to activate diversion for his own AdC, he shall be warned that
suspension of the already activated diversion of calls to his AdC shall occur. During this period the calls to
the originally diverted AdC shall be rejected (see ETS 300 133-3 [2], subclause 7.2).
Procedures
- provision:
- Provision of this service shall be optional for the network operators. Diversion outside home
network can only be provided if there is an agreement between the network operators and/or
the operators of other systems involved.
- normal procedures:
- The service should be made available to mobile subscribers on a registration basis or on
demand, according to the network operator's policy. Diversion shall be activated by the
subscriber after authentication. Activation shall be for a specific period of time. It can be de-
activated either automatically by the PNC when activation time has expired or by the
subscriber (after authentication) before the activation time expires.

Interaction with other services
A check shall be made to avoid diversion to AdCs having lower categories of subscriptions. Only those
supplementary services supported by the divert recipient's Home PNC (PNC-H) and the divert recipient's
receiver can be provided during the period of diversion. The mobile subscriber can not activate any
supplementary service, except temporary barring, after activation of diversion of traffic. Request for
diversion to another AdC shall suspend the previous divert request. The supplementary services that the
mobile subscriber has already activated shall be suspended.
Activation for a group using common RIC affects the whole group. In the case of Closed User Groups
(CUGs) it shall be possible to divert the call only within the CUG.
The diverted messages shall follow the message numbering of the divert recipient.
Calls shall be accepted and processed even if the divert recipient does not have all the supplementary
services of the subscriber who has activated the service. The calling party shall not be informed that these
supplementary services are not supported by the divert recipient.
4.3.1.2.3 Choice of destination
Definition
A service to give the calling party the facility to choose the geographical areas that he wants the call to be
transmitted in. The calling party has the following alternatives:
- transmission according to the mobile subscriber location register;
- transmission in one or more areas in addition to the location register.
Procedures
- provision:
- Provision of this service shall be optional for the network operators. Subject to the policy of
the network operator, the service may have restrictions on the number of geographical areas.

Interaction with other services
When choice of destination is activated and transmission outside home network of the subscriber is
requested, level 1 priority can not be used. Level 3 priority and urgent message indication can only be
activated if they are provided in the requested geographical areas.
If the called mobile subscriber has activated diversion of calls this service can not be activated.
4.3.1.3 Supplementary services related to protection against loss of messages
The method used by the system to indicate the loss of a message to the receiver or the mobile subscriber
is to allocate a number to each message before transmission. The system shall have one message
counter (1 to 31) per RIC. A message number (modulo 32) shall be allocated sequentially in increasing
order from 1 to 31 to all messages.
The message number may be provided by the network operator.
The receiver shall have the capability to detect the message number and may take appropriate action
(according to receiver specification).
If the message number is not provided with a paging message, the dummy value (00000) shall be used in
the message header.
4.3.1.3.1 Repetition
Definition
The facility of the calling party and/or the mobile subscriber to request automatic message repetition.
Repeated messages shall be transmitted within an operator defined time interval from the initial message
transmission.
The default value is 5 minutes. In an external network the maximum time between the reception of the first
and last message may be increased due to difference of priority in both networks.
The number of repetitions is an operator defined parameter.
The repeated messages shall have the original message number (see message control in the receivers).
Procedures
