摘要:
A communication system and a method for the same is disclosed. In the method a first type of communication services is provided for a station (1), wherein a first network entity (3) provides control operations for the provision of the communication service. A part of said control operations is then relayed from the first network entity (3) to a second network entity (4). Information is exchanged between the first and second network entities, said information associating with provision of a second type of communication services for the station. A communication service of said second type is provided for the station based on said information.
摘要:
A method of transmitting data between first and second network entities in a communications network, the method including, transmitting from the first network entity an establishment message providing a first indication which indicates whether the first network entity is capable of handling extended messages, receiving the message at the second network entity and returning to the first network entity an establishment response which provides the first indication in respect of the second network entity, and transmitting a data message from the first network entity to the second network entity, the data message selectively being an extended message in dependence on the first indication received in the response message, the data message further providing a second indication which indicates whether or not the data message is an extended message.

The present invention relates to a method and a controller for a radio communication system. The system comprises a plurality of location areas. The controller serves said location areas and mobile stations within said location areas. In accordance with the method a request for initiation of location area information update proceedings is received at the controller. The controller then verifies whether the mobile station is subjected to a simultaneous paging procedure. If a simultaneous paging procedure is detected, the location area information update proceedings are interrupted and an acknowledgement message is generated and transmitted, said message informing the mobile station that the location area information update proceedings are completed.
摘要:
A cellular radio access network and a location updating in a cordless communications system, in a cellular radio access network (1), which is connected to one or more core networks (2, 3, 4, 5) or services (SP2 to SP5), each of them having a dedicated mobility management. In a cell, identities of all those location areas are broadcast to which said cell belongs. A subscriber terminal (MS) sends to the radio access network only one location updating message irrespective of how many core networks (2, 3, 4, 5) or services (SP2 to SP5) have a simultaneously changing location area at a handover from one cell to another. On the basis of the information contained in the location updating message, the network (1) defines the core networks or services and location areas to which the location updating applies and sends a location updating message informing the new location of the subscriber or the subscriber terminal separately to each defined core network or service.
摘要:
The present invention is a novel and improved method for managing in a single location the ciphering keys and algorithms used for encrypting or ciphering the communications of a specific mobile station with multiple core networks or core network entities. Further another aspect of the invention is that the management location is movable as the mobile station moves within the radio access network.

A method for performing an inter-system handover of a user terminal in a telecommunications network comprising a first telecommunications system operable according to a first protocol and comprising a first service subsystem and a first access subsystem and a second telecommunications system operable according to a second protocol and comprising a second service subsystem and a second access subsystem; the user terminal storing capability data indicative of the user terminal's capabilities for communication with the service subsystems and the access subsystems.
摘要:
The basic idea of the invention is to separate the location area used in the RAN and the reporting area used when reporting the location of the mobile to the core network. The size of the location area is selected preferably in the RAN based on the services used by the subscriber to optimize the use of radio resources. A reporting area comprises one or a plurality of location areas. The size of a reporting area is selected based on the accuracy of location information needed in the core network. The RAN informs the core network when a subscriber moves out of his current location area. The core network and the radio access network negotiate the size of the reporting area prior to the activation of the service. Additionally, the reporting areas can be renegotiated when the service is in the active state.
摘要:
A method and system is disclosed for performing a location registration in a cellular communication network, wherein a subscriber identity of a user equipment is analyzed when a location registration request has been received, and a priority is allocated to the subscriber based on the result of the analysis. Then, the location registration request is admitted or rejected based on the allocated priority and a detected network load. Thereby, the network operator is able to guarantee network services for home subscribers in cases of increased network load.
摘要:
A communication network is established by a connection to a user terminal that is capable of roaming amongst a plurality of serving areas. The network includes a controller for each serving area capable of routing a connection to a location covered by that serving area. If a controller serving the user terminal is faulty, a home database, which stores a plurality of identities of other controllers, is able to route the connection to the user terminal by selecting one of the other controllers that is valid.
