27、Release 151 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 del

28、ivery 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 chan

29、ges 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 App

30、lication Servers such as a Push Proxy and Push Initiator will be undertaken by other standards bodies and industry forums. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. - References are either specific (i

40、ent document, the terms and definitions given in TS 22.174 3 and the following apply. delivery network: transfers Push Data from Push Function to UE in a connectionless or connection oriented manner. A delivery network may be a GPRS bearer service. Application Server: a server that provides push ser

41、vices through a delivery network, e.g. via an IP connection user IP address: an IP address provided by the delivery network that can be used by an Application Server to provide push services to a user. The address may be permanently assigned (static) or temporarily assigned (dynamic). user-ID: an id

42、entity or name that can be used to deliver push content to a user in a delivery network. The format of user-ID is dependent on the protocol for the push services. user availability: the ability of an delivery network to transfer data to a subscribed user. long-lived PDP Context: a PDP Context that r

43、emains active/open for an indefinite period of time. Also referred to as “always-on PDP context“. always-on PDP Context: this is a PDP Context that remains active/open for an indefinite period of time. Also referred to as “long-lived PDP context“. PDP Context: Push Data: data sent by the push initia

44、tor to the Push Recipient. Push Function: the entity 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. Push Initiator: the entity that originates Push Data and submits it to the Push Function for deli

45、very 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 applica

46、tion level address, and the device, machine or person which uses the Push Data. Push service: a service capability offered by the PLMN that transfers 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

47、 as a basic capability or as component of a value added service. Push User agent: 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. ETSI ETSI TR
