Digital Enhanced Cordless Telecommunications (DECT); Integrated Services Digital Network (ISDN); ISDN Mobility protocol Interworking specification Profile (IMIP); Part 2: DECT/ISDN interworking for Global System for Mobile communications (GSM) support

This standard specifies a set of technical requiremens for Digital Enhanced Cordless Telecommunications (DECT) Fixed Parts (FP) supporting connection, via an ISDN interface, to a network supporting terminal mobility. Part 1 of this standard (DEN/DECT-030126) specifies the interworking procedures between the DECT air interface and the mobility management protocols defined for ISDN interface, to support CTM mobility. This Part 2 of this standard specifies the interworking procedures between the DECT air interface and the mobility management protocols defined for an enhanced ISDN interface, to support GSM mobility.
