Abstract: 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.

Abstract: Provided are a method and a device of a host with IPv4 application for performing communication. The method of the host with IPv4 application for performing data communication includes the following steps: the IPv4 application generates an IPv4 packet sent to a communication end; when confirming the type of the network the host is located in is an IPv6 network, the host transforms the IPv4 packet head of the IPv4 packet to an IPv6 packet header, and sends it to the communication end via the IPv6 network. With this invention, it can be accomplished that according to the type of the network the host is located in, the host with IPv4 application communicates with a communication end; the processing load of the system is lightened; the probability that invalidation occurs at a single node is reduced; the smooth migration and transition from original IPv4 application to IPv6 system are facilitated.

Abstract: 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.

Abstract: 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.

Abstract: The present invention relates to a data storage method, device and system and a management server. The data storage method includes: constituting a data pool from all of n data storage devices; when there is data for storage, polling all the devices in the data pool to select a group of m devices, and storing the data onto each of the selected group of m devices, where m is larger than one and smaller than n. The embodiments of the invention can address the problems of an existing data storage approach that a failing node causes an increased load on and instability of another node and that each node in the existing data storage approach has a low utilization ratio and poor predictability, so as to achieve uniform loads on the devices and high reliability of the nodes despite any failing node and improve the resource utilization ratio and predictability of the nodes.

Abstract: A method, a system, and a network element for service processing after data of a network element is invalid or a network element fails are provided. When the service network element (1) receives the service request message from the network and initiated to a called end and the user data is invalid, the service network element (1) returns a data invalid message of the called end to the network. When a network element containing registration data of a user is abnormal and the registration data of the user is invalid, by using the present invention, the service unavailable time is shortened, and user services can be recovered rapidly.
