    摘要: A method to transfer control is presented. The method includes sending a message requesting transfer of control of a collaborative session, and receiving notification, in response to the sent message, indicative of a transfer result of said requested transfer of control. The method may include, when the transfer result in the received notification indicates success, relinquishing control of the collaborative session. The method may include maintaining control of the collaborative session independent of the transfer result in the received notification. The message requesting transfer of control of a collaborative session may also comprises a request for media transfer.

    摘要: A method performed by a first network node of an IMS Network is provided. The method includes receiving a Uniform Resource Identifier (URI) in a header field in a first SIP message; receiving a token in the header field in the first SIP message, the token indicative of a type of a network node in a path of the first SIP message; and based on the received token, sending a second SIP message including the received URI, the second message conveying information about the first network node.

    摘要: A user agent (UA) for communicating with a communications network implementing an internet protocol (IP) multimedia subsystem (IMS) is presented. The UA is configured to send and receive session initiation protocol (SIP) messages. The UA includes a processor configured to send a message to the network. The message identifies an application policy. The application policy defines at least one of a SIP message header field to include, a SIP message header field to remove, a SIP message header field to allow, and a SIP message header field to modify. The processor is configured to receive a SIP message from the network. The SIP message includes a set of SIP message header fields. The set of SIP message header fields are modified in accordance with the application policy.
