Embodiment Construction

[0037] The following discussion presents two solutions to the problem of enabling a content server to distribute one or more media types to participants of a Push to Talk over Cellular session. To facilitate media sharing, three main questions must be asked:

[0038] How does the PoC server understand that the user wants to share media?

[0039] How can PoC users identify media?

[0040] How does a PoC user instruct a content server what to share in a PoC session?

[0041] A first method consists in joining the content server as a PoC client to the PoC session, so that the content server is (temporarily) added to the PoC session. To illustrate this approach, consider an ongoing PoC session between PoC clients A and B, where each PoC client has participating PoC servers (PoC servers A and B), and the session is controlled by the controlling PoC server (PoC server X). control. figure 1 The main SIP requests and SIP responses associated with this method are shown, where PoC v...

Abstract

A method of distributing media from a network based content server to two or more clients participating in a burst-based service session. The method comprises, following establishment of said session, joining the content server to the session as a further participating client, sending a media grant to the content server, and delivering the requested media from the content server to the other participating clients.

Description

technical field [0001] The present invention relates to a method and apparatus for sharing media in a push-to-talk type session. Background technique [0002] Walkie-talkie (walkie-talkie) type services have long proven popular among users who want to communicate short messages quickly with each other. Traditionally, these services have been provided by two-way portable radios utilizing a dedicated portion of the radio spectrum, but only allow users to communicate with a small group of preselected users who utilize similar terminals and are within the short operating range of the radio . More recently, services have been introduced to the United States over the existing cellular telephone infrastructure. However, these services have been private in nature and have not yet allowed users to communicate between different operator networks. [0003] Hoping to expand the use of walkie-talkie-type services, an industry group known as the Open Mobile Alliance (www.openmobilealli...
