Disclosed are an access session controller, an IP multimedia subsystem and registration and session establishment methods thereof, where the access session controller includes a message reception module, a service trigger configuration module, a session control module and a message transmission module. The IP multimedia subsystem includes the access session controller and a network-wide home subscriber server system. The registration method includes: initiating, by the access session controller, an authentication information request to the network-wide home subscriber server system. The session establishment method includes: directly process, by the access session controller, the request message initiated from a user to establish a session. The foregoing solutions can simplify the signaling processing flow and reduce the network complexity.

The present invention discloses a data storage system in a communication network, which enables distributed storage of data. The system includes front end nodes, storage nodes, super nodes and management nodes. The operation units are located in the front end nodes, the super nodes or the storage nodes and each adapted to operate a first data GUID by a preset fixed offset to derive a second data GUID, to determine, from loop link information obtained from the management node and the second data GUID, a super node with a node identifier closest to the second data GUID, and to forward a service request carrying the second data GUID and a backup flag to the determined super node. The invention further discloses a data information processing method using the system.

Data storage system in communication network and data information processing method

A communication network system includes a resource network element and further includes a resource server adapted to retrieve availability information of the resource network element and to allocate the resource network element according to the retrieved availability information. A service processing method in a communication network at the resource server side includes: receiving a resource query request; and searching for an available resource network element and responding with it being a response result. A service processing method in a communication network at the resource network element side includes: receiving a request for a service; determining whether the service can be processed immediately, and if not, transmitting a resource query request to a resource server; and transmitting the service request to an available resource network element in a response result. A resource server and a resource network element are further disclosed. With a resource server, the invention can monitor dynamically availability information of a resource network element and allocate appropriately an idle resource network element to thereby improve both a utilization ratio of network resource and a service processing capability of network element.

A method and device of session control are used to resolve the problem that when there is a failure in the session control function bound with the user, the UE can not re-login in time or the session can not be continued. In the flow of the user initial login, an address information of P-CSCF bound with the user in HSS is saved, so that when the user is called, an available S-CSCF can get the address information of P-CSCF bound with the called user from the HSS, and inform the user to do re-initial login according to the address information of P-CSCF or complete the session continuation; further, the address information of the user in D-HSS is saved, so that when the user is called, an available A-CSCF can get the address information of the called user from the D-HSS, and inform the user to do re-initial login according to the address information of the called user or complete the session continuation.

Method and device of session control

A method, node and system for controlling version in a distributed system. Wherein, the method includes: a management node is selected from each domain of the distributed system; one is selected as the synchronization source of the distributed system from all the management nodes, and all the management nodes synchronize the time with that of the synchronization source; all the management nodes control the time synchronization of the nodes in their own domain according to the synchronized time; the nodes of the distributed system control the version of the duplicate copy of the storage data according to the synchronized time. According to the technical scheme, it can be realized that the rough time synchronization of the distributed system, the expansibility and the practicability are improved, and the defects of the distributed system in the prior art, such as the poor expansibility and practicability, are solved.
