A method of managing subscriber data in a communication network, the method comprising: sending a message associated with a subscriber and including data relating to the identity of said subscriber; routing said message to a first network entity based on identity and routing information stored at a register; subsequent to receiving said message at the first network entity provisioning a second network entity with subscriber data required by said second network entity to be able to service said subscriber; and updating routing information associated with the subscriber at the register to route subsequent signalling to the second network entity.

Method and apparatus for storing subscriber data

A communication system includes a plurality of first entities. Each of the plurality of first entities includes at least one database. The system also includes at least one second entity being dedicated to at least one of the plurality of first entities. The at least one second entity includes data from databases associated with the plurality of first entities. The system further includes a third entity for determining when one of the plurality of first entities malfunctions and for selecting another one of the plurality of first entities as a redundant entity. The at least one second entity is associated with the redundant entity and data is retrieved from the at least one second entity to process incoming requests to the redundant entity.

Full redundant service register in the multi-vendor network

Authentication method for authenticating a mobile node to a packet data network, in which a shared secret for both the mobile node and the packet data network is arranged by using a shared secret of the mobile node and a telecommunications network authentication centre. In the method, the mobile node sends its subscriber identity to the packet data network together with a replay attack protector. The packet data network obtains authentication triplets, forms a session key using them, and sends back to the mobile node challenges and a cryptographic authenticator made by using the session key. The mobile node can then form the rest of the authentication triplets using the challenges and then form the session key. With the session key, the mobile node can check the validity of the cryptographic authenticator. If the authenticator is correct, the mobile node sends a cryptographic response formed using the session key to the packet data network for authenticating itself to the packet data network.

Disclosed herein is a method and apparatus for measuring usage of system resources in a communication network. The apparatus includes devices for measuring radio resources, data service units and transmission characteristics in the system. The devices for measuring are adapted for performing a respective collective measurement. The method includes collectively measuring transmission parameters including radio resources, data service units and transmission characteristics. The method provides for dimensioning system resources according to transmission demand in the network.

Device and method for measuring the usage of system resources in a communication network

Methods and apparatus for signal monitoring of messages in a telecommunications network having a plurality of switches and network elements therein alleviate the need for external hardware to be hooked up to nodes of the network to determine whether faults have occurred at the nodes. A signal monitoring application disclosed herein stores related message signals and messages in a relational database wherein messages and signals having common elements can be easily and quickly viewed. The SIMO application cross-references the messages and signals in the relational database according to a transaction table which categorizes and stores the messages according to parameters set out in the transaction table. This allows the messages to be ranked and viewed very quickly without the need to process them and expend valuable computational time and resources.

Transfer of SS7 signalling message contents over packet broadcasting network (LAN) from multiple signalling points to single point (multiple point-to-point)

In the present invention, a measuring device is proposed for measuring system resources which are used by a communication connection in a telecommunication network, said device comprising: means for receiving a request of allocation of system resources to establish said connection, said request indicating a preferred level of said resources, examining means ( ) for examining parameters (BCIE ) indicating said requested resources, allocating means ( ) for allocating, on the basis of the examination by said examining means ( ), available resources indicated by parameters (BCIE ) of the communication network to the communication connection, and comparing means ( ) for comparing the level of the requested resources (BCIE ) and the level of the resources allocated by the communication network (BCIE ). Furthermore, a corresponding measuring method is proposed. Using the present invention allows a operator to obtain improved knowledge of system resources.
