摘要:
A technique for hiding network element names and addresses in communications between first and second networks includes providing a message generated by a network entity in the first network to be delivered to a target network entity in the second network, the messaging including first and second parts. The message generated by the network entity in the first network is routed to a contact point disposed between the first and second networks in accordance with the first part of the message and the message generated by the network entity in the first network is routed from the contact point to the target network entity in the second network in accordance with the second part of the message.
摘要:
The invention proposes a network system comprising a first network element (2) and at least a second network element (3), the second network element being adapted to operate in at least two different modes, wherein the first network element (2) is adapted to send a message to the second network element, and the second network element (3) is adapted to set the mode in response to information included in the message and indicating whether a particular procedure is to be performed and/or has been performed. Thus, the second network element sets its mode dependent on whether a procedure like processing of a location request has to be performed or has not to be performed, or, whether a procedure has been performed or not. The network elements can be Call State Control Functions (CSCF).

摘要:
An emergency telephone call is supported and routed to a Public Safety Answering Point (PSAP) in an IP based packet switched wireless communications network. An activate PDP context request is sent from a user equipment to the network. A parameter in the activate PDP context request indicates that the PDP context will be used to transfer an emergency call. An activate PDP context accept message is returned from the support node to the user equipment. The activate PDP context accept message acknowledges the activate PDP context request message and provides the address of a call state control function. A call setup request transferred to the call state control function includes the Service Area Identity (SAI). The call state control function selects a PSAP based, at least in part, on the SAI included in the call setup request and forwards the emergency call to the selected PSAP.

A switching center of a wireless communications network, the switching center comprising an internet gateway node integrated therein for accessing user information internally within the switching center and arranged to use the user information for at least one of: provision of services to an internet service provider from the wireless communications network; provision of services from an internet service provider to the wireless communications network; and provision of services by the internet service provider within the internet.
摘要:
There is disclosed a technique in which there is allocated one of a plurality of serving call state control functions to a subscriber, the technique including: receiving load information from at least one serving call state control function; and determining a serving call state control function for the subscriber in dependence on the received load information, wherein the receiving step includes receiving the load information during subscriber registration in a signal received from a serving call state control function to an interrogating call state control function.

The invention relates to a communication method and system wherein a network element of a roaming user is attachable to a visited first network and be served by a serving means of the home network. When the network element of the roaming user is registering or initiating a connection to a called network element of the visited network, a network element of the visited network, such as proxy means, either adds information on the called network element or on a service element of the visited network when sending a message to the home network. The message is preferably sent as a protocol message, in particular a message of the Session Initiation Protocol.
摘要:
A communication system including a first administrative subsystem and a second administrative subsystem providing group communication service. The system includes a first server for storing group and list management information of subscribers of the first administrative subsystem. The system also includes a second server for storing group and list management information of subscribers of the second administrative subsystem. Further, the system includes an interface for exchanging group and list management information between the first server and the second server. In addition, the system reduces ambiguity in group information management of integrated systems that include two or more administrative domains.
