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.
