DS TR 123 976 V15.0.0:2018

Universal Mobile Telecommunications System (UMTS); LTE; Push architecture (3GPP TR 23.976 version 15.0.0 Release 15)

Scope

The purpose of this technical report is to analyse the service requirements for push services as defined in TS 22.174
"Push service; Stage 1". It continues the work of TR 23.875 (3GPP internal report).
This technical report describes methods for supporting push services by 3GPP delivery networks. The mechanisms
described apply to existing delivery networks for the 3GPP Packet Switched (PS) domain, Circuit Switched (CS)
domain, IP Multimedia Core Network Subsystem (IMS), Multimedia Broadcast / Multicast Service (MBMS), and
Wireless Local Area Network (WLAN). Any necessary changes identified during this work will be introduced by
means of change requests to the appropriate specifications.
The definition of Push Functionality that applies to push Application Servers is outside the scope of this work. The
definition of Push Functionality that is best implemented in push Application Servers such as a Push Proxy and Push
Initiator will be undertaken by other standards bodies and industry forums.
