Control entity and method for setting up a session in a communications network, subscriber database, and communications network. The control entity advantageously has or has access to memory for storing information, and typically includes an input device for receiving a request to set up a session in the communications network, a processor unit for processing the request, and an output device for sending messages. The processor unit is arranged to determine if the request comprises a valid Communication Service Identifier (CSI) the CSI identifying the type of communication service of the session that is to be established over the communications network. And if the request does not comprise a valid Communication Service Identifier, to execute a default CSI procedure using default CSI information stored in the memory.

Control entity and method for setting up a session in a communications network, subscriber database and communications network The invention relates to a control entity for setting up a session in a communications network, comprising an input device for receiving a request to set up a session in the communications network, a processor unit for processing the request, and an output device for sending messages. The control entity further comprising or having access to a memory for storing information. The processor unit is arranged to determine if the request comprises a valid Communication Service Identifier, CSI, the Communication Service Identifier identifying the type of communication service of the session that is to be established over the communications network. And if the request does not comprise a valid Communication Service Identifier to execute a default CSI procedure using default CSI information stored in the memory.
摘要:
A method of facilitating access to services of an IP Multimedia Subsystem network by user terminals located behind an access point to said network. The access point is associated with a subscription to the IP Multimedia Subsystem network. The method comprises including within an Implicit Registration Set defined for said subscription, a wildcarded Public User Identity or Public User Identity sub-domain representative of a range of Public User Identities. At IP Multimedia Subsystem registration of said access point with the IP Multimedia Subsystem network, the Public User Identities contained in the Implicit Registration Set are distributed to a Serving Call Session Control Function allocated to said access point and to a Proxy Call Session Control Function to which said access point is attached.
摘要:
A method and apparatus for handling a Session Initiation Protocol message in a communications network. When a network node receives a Session Initiation Protocol message, which comprises Request-URI header, the node rewrites the Request-URI header in the SIP message, and adds information to the SIP message useable by a remote node to determine the current target address of the message. The SIP message is then sent to a further node. In this way, the remote node that receives the message can determine the current target in the SIP message, even if the target has been re-written in the Request-URI as the result of, for example, a translation or re-routing operation.

A Session Initiation Protocol Application Server of an IP Multimedia Subsystem having processing means for handling a message received from a Serving Call/State Control Function, the means being arranged to handle the message based upon a header of the message containing the URI of the served user, this header having been introduced by the Serving Call/State Control Function and being other than the P-Asserted Identity and the R-URI.
