Introduction
The Push Service introduces a means to transmit push data from a push initiator to a push recipient (e.g. a UE) without
a previous user action. The push concept, as provided by the SMS teleservice, has been very successful in the GSM
second generation, both for text messaging (for user viewing) and for other unstandardized data to the SIM (as a
building block used for OTA and other purposes). This TS introduces the Push Service as a generalization of existing
network capabilities plus the development of new capabilities. The Push Service should therefore be understood as a
building block (network capability), which can be used for new services, both public and private, in 3GPP.
In the normal client/server model, a client requests a service or information from a server, which then responds in
transmitting information to the client. This is known as the "pull" technology, the user pulls information from the
content provider. The World Wide Web is a typical example of pull technology, where a user enters a URL (the
request) that is sent to a server and the server answers by sending a Web page (the response) to the user.
In contrast to this there is also the "push" technology where there is no explicit request from the user before the content
provider (push initiator) initiates an information transfer to a user. Another way of saying this is that whereas "pull"
transaction of information are always initiated from the user, "push" transactions are content provider initiated.
The welcome message received after registration with a visited network whilst roaming is an example of information
transfer that has been initiated without a request from the user. Typically, a user signs up with the push initiator and
defines their interest, volume of information acceptable and other factors in the push subscription profile. As
information becomes available that satisfies the user’s push subscription profile, the push initiator delivers it to the user
using the Push Service.
The Push service may be used to implement high level services such as IP multimedia services, MMS, etc., and new
services including public safety, government, corporate IT, transfer of push data to machines and devices, in addition to
infotainment type services.
Another common use for push services is the delivery of notification from e.g. MMS to the user while the user has the
option of "pulling" the actual push data from the push initiator.
The PLMN Push function provides the push data to the user agent in the UE. The user agent interprets and presents the
push data to a person, device or machine using the UE.
NOTE: The requirements of services such as streaming, conversational services and broadcast are independent
from push. Therefore they are not considered appropriate for inclusion here. Push will be available for use
in appropriate applications of all high level services.

1 Scope
This Technical Specification defines the Stage 1 description of the Push Service and is the set of requirements that shall
be supported for the provision of push, seen primarily from the subscriber’s, service providers’ and delivery network
points of view.
This TS includes information applicable to network operators, service providers, terminal and network manufacturers. It
is of use to manufacturers and organisations which have devices or machines benefiting by availability of push service.
This TS contains the core requirements for the Push Service, for operator and external Push Initiators, which are sufficient
to provide a complete service capability and service capability feature.
This TS defines the requirements for the Push Service to enable delivery of push data, including such functionality as:
• Transfer of push data from a Push Initiator to a Push Recipient
• Latency and Priority classes,
• Definition of handling of undeliverable push data.

3 Definitions and abbreviations
Definitions and abbreviations used in the present document are listed in TR 21.905 [2]. For the purposes of this
document the following definitions and abbreviations apply:
3.1 Definitions
Push Data: data sent by the push initiator to the push recipient, of a format known to the receiver (push recipient), and
not otherwise defined by the push service.
PLMN: the 3GPP network that receives the push data from the push initiator and ensures the delivery of push data to
the push recipient. The delivery of the push data may involve other networks.
Push function: the function in the PLMN that receives the Push Data from the Push initiator. The push function is
responsible for delivering the push data to the Push recipient.

3GPP TS 22.174 version 15.0.0 Release 15 6 ETSI TS 122 174 V15.0.0 (2019-07)
Push initiator: the entity that originates push data and submits it to the push function for delivery to a Push recipient. A
Push initiator may be e.g. an application providing value added services.
Push recipient: the entity that receives the push data from the Push function and processes or uses it. This may include
the UE with which the PLMN communicates with, the user agent with the application level address, and the device,
machine or person which uses the push data. A Push recipient is controlled by an individual user .
Push service: a service capability offered by the PLMN. The Push Service is initiated by a Push Initiator in order to
transfer push data (e.g. data, multimedia content) from the Push Initiator to the Push Recipient without a previous user
action. The Push Service could be used as a basic capability or as component of a value added service.
Push User agent: is any software or device associated with a Push recipient that interprets Push Data to the user. This
may include textual browsers, voice browsers, search engines, machine or device interface software, etc.
Push Subscription Profile: a set of parameters indicating the Push recipient’s settings and preferences for the Push
Service.

4 Overview of the Push Service
The overview of push is followed by a summary of the relationships among the entities involved (operators, users, push
recipients and push initiators).
NOTE: these are functional descriptions: multiple functions may, depending on business arrangements, be performed
by a single entity.

The Push Service is a service whereby the Push Initiator sends push data through a Push Server to a Push Recipient,
without interaction from the Push Recipient.

The typical mode of operation is as follows:
• A Push Recipient (e.g. user, receiving device like a meter) explicitly or implicitly subscribes to a set of value
added services offered by various Push Initiators and allow these Push Initiators to send it push data that meet
the Push Recipient’s configured criteria. (This configured criteria is part of the Push user profile.)
• A Push Initiator identifies information matching the criteria set by the Push Initiator and package it up into the
push data
• The Push Initiator delivers the push data to the Push function, identifying the Recipient’s address, and
optionally priority, delivery time parameters, etc.
• The Push function takes the responsibility of delivering the push data, optionally following the priority and
delivery time parameters, to the Push Recipient and for providing feedback to the Push Initiator regarding
delivery of the push data if requested by the Push Initiator.
Key characteristics of the Push Service include:
• The Push Initiator may, but is not required to deal with the specifics of the wireless transport, selection of
appropriate bearers, out-of-coverage or roaming issues, and other wireless network anomalies. These are all
managed by the Push Service and hence can be optimised at the network level rather than being han
