    摘要: The invention is a method of determining in at least one communication network if a session should be established in at least one communication network containing a plurality of session established entities, a method for determining if a session should be established with caller user equipment requesting the session, and in at least one communication network, a method for determining if a session should be established from caller user equipment at at least one communication network. A method of determining in at least one communication network if a session should be established in accordance with the invention includes processing a request from caller user equipment (114′) to establish a session with callee user equipment (114) in the at least one communication network (102 and 104) with a session establishment entity (108, 110, 112 and 114) to determine if at least a portion of the request (140 and 142) exceeds a size limit and establishing the session (146) if at least the portion of the request is determined by the session establishment entity to not exceed the size limit.

    摘要: Various methods for determining network entity timeout values to improve keep-alive signaling are provided. One example method may comprise providing for transmission of a request for a timeout value associated with a keep-alive timer. The method of this example embodiment may further comprise receiving a response to the request, wherein the response comprises an indication of the timeout value of the keep-alive timer. Additionally, the method may further comprise determining an expiration time of the keep-alive timer based at least in part on the timeout value. The example method may further comprise providing for transmission of a keep-alive data packet prior to the determined expiration time. Similar and related example methods, example apparatuses, and example computer program products are also provided.

    摘要: This invention relates to a SIP and SDP protocols. The idea of the invention is to modify SDP descriptions included in SIP messages to facilitate transcoding. After receiving an INVITE message from a calling party, the SIP proxy negotiates with a transcoder for getting a list of codecs of the transcoder and their address information. The SIP proxy adds the codec list of the transcoder to the received SDP description in the invite message, and sends this way modified SDP description in an INVITE message to a called party. After receiving the modified SDP, the called party selects codecs or a list of suitable codecs according to preferences in the modified SDP and its own preferences.
