摘要:
One illustrative technique is performed in a requesting terminal of a plurality of terminals of a communication group for a communication session delivered via a network. Each terminal has communication capabilities within the communication group, such that a currently-transmitting terminal in the communication group is given a transmit capability using a talk channel while all other terminals of the communication group have a receive capability. The requesting terminal, which is not the currently-transmitting terminal, receives a user input for selecting a responding terminal of the communication group for responding in the communication session. The requesting terminal then transmits, while the transmit capability is given to the currently-transmitting terminal, a request for the network to grant the responding terminal the transmit capability. The request includes an identification of the responding terminal.

摘要:
A method for a user agent to access a session policy in a network is provided. The method comprises the user agent receiving in a header field of a response message a plurality of uniform resource identifiers (URIs) for a policy server, wherein each of the plurality of URIs uses a different policy channel protocol.
摘要:
A method is provided for delivering the capabilities of user agents. The method includes a user agent sending a session initiation protocol (SIP) message containing a Contact Header containing a Push Resource Identifier feature tag containing at least one push resource.
