Embodiment Construction

[0048]An embodiment of the invention is based on the procedures defined by OMA PoC (see: OMA PoC Requirements Document Version 1.0 OMA-RD-PoC-V1_0; OMA PoC Control Plane Document Version 1.0 OMA-TS-PoC-Control Plane-V1_0; OMA PoC User Plane Document Version 1.0 OMA-TS-PoC-User Plane-V1_0; and OMA PoC XDM Specification Document Version 1.0 OMA-PoC_XDM_Specification-V1_0, Open Mobile Alliance, http: / / www.openmobilealliance.org / ) with something added to implement passing the session or part of it.

[0049] As an example, consider the situation where a user of a PoC client wishes to transfer at least part of his / her PoC session to another PoC client on another device. The reason may be that this other device has more capabilities, such as video capabilities. Delivery can be just a part, such as a video part, or receive a picture or video clip or file. The decision to deliver the PoC session may be a user decision or a PoC client decision. For example, according to one embodim...

Abstract

A method is provided of transferring at least part of a push to talk type session from a first terminal (PoC Client A) to a second terminal (PoC Client C). In the method, a Session Initiation Protocol, SIP, REFER message is sent that indicates which part, or that the whole, of the session is to be transferred. In one example, the SIP REFER message is sent from the first terminal (PoC Client A) to a server (PoC Server X) designated to control the session. In response to receipt at the server (PoC Server X) of the SIP REFER message, a SIP INVITE message is sent to the second terminal (PoC Client C). The SIP REFER message may comprise information identifying the second terminal, for example the address of the second terminal, which may be a Push to talk over Cellular, PoC, address, such as a SIP URI or a TEL URI, or a Globally Routable User Agent URI, GRUU.; The push to talk type session may be a session in a Push to talk over Cellular, PoC, service, for example, or it may be a session in a conferencing service.

Description

technical field [0001] The present invention relates to methods and arrangements for push-to-talk type services, such as so-called push-to-talk-over-cellular services. Background technique [0002] Walkie-talkie-type services have long proven popular among users who wish to quickly send short messages to each other. Such services have traditionally been provided via two-way portable radios that utilize a dedicated portion of the radio spectrum but allow users to communicate only with a small group of preselected users using similar terminals and within a short operating range of the radio . Recently, services piggybacked on existing cellular telephone infrastructure have been introduced in the United States. However, these services are proprietary in nature and do not allow users to communicate between different operator networks. [0003] In an attempt to broaden the use of walkie-talkie-type services, an industry group called the Open Mobile Alliance (www.openmobilealli...
