A location update method, and a heterogeneous network communications system and a device are provided herein. The method includes: an information server receives a location update request message from a multimode terminal; the information server searches the pre-stored location area mapping information for the location area information of the second interface; and the information server sends the location update request message of the second interface to a second Paging Coordinator (PC) corresponding to the second interface, where the request message carries the found location area information of the second interface so that the second PC can update existing location area information of the second interface. The system includes an information server, a first PC and a second PC. Therefore, the interfaces of the multimode terminal do not need to initiate location update frequently, message interactions between the terminal and the network are reduced, and not all interfaces of the multimode terminal need to report location area information, thus saving power.

The present invention discloses a figure-picture downward transferring method comprising: a step of S402, a communication terminal sending a petition signal toward a first communication device; a step of S404, the first communication device responding to the petition signal and sending a notice signal to a second communication device; a step of S406, the second communication device responding to the notice signal and sending an identification code to the first communication device; a step of S408, the first communication device responding to the identification code and citing the figure-picture which is corresponding to the identification code; and a step of S410, the first communication device downwardly transferring the figure-picture to the communication terminal. The present inventionalso discloses a generation method of figure-picture mapping used for establishing a corresponding relationship between the figure-picture and the identification code, which includes: establishing the identification code corresponding to the figure-picture at the second communication device; the second communication device sending a first information containing the figure-picture and its corresponding identification code to the first communication device; and the first communication device receiving and recording the first information come from the second communication device.

The invention relates to a distributed data storage processing method in UTRAN coordinated calling, applied to UTRAN coordinated calling in radio network control (RNC) system, and including: A) dividing RNC system into plural relatively independent processing subsystems, establishing a data storage region in each processing subsystem; B) as a user equipment accesses to a processing subsystem of the RNC, adopting distributed storage algorithm to store data record cells of the user equipment into a corresponding data storage region; C) as kernel network initiates UTRAN coordinated calling, some processing subprogram of the RNC obtains the property parameters of the called user equipment by calling information and adopts the distributed storage algorithm to locate the data storage region where the data record cells of the user equipment to read the data record cells. The method can effectively improve the whole performance of UTRAN coordinated calling of RNC system.

The invention discloses method and system for terminal to reenter into network in wireless communication network in order to quicken accessing network. When terminal reenters into network, using connection configuration information held on network by base station and terminal, and through switching optimized indication domain protocol, the method speeds up procedure for terminal to access network. The system includes base station access control device, terminal access control device, base station access information memory, and terminal access information memory. Since terminal and base station can use configuration parameter at previous connection, the method does not need to carry out negotiation so as to quicken access speed, and save resources of aerial interface.

The embodiment of the present invention provides a method and device for media coding format conversion based on CSCF. The method includes: when the media coding format negotiation between the called terminal UE2 and the calling terminal UE1 fails, receiving the call session control entity CSCF The first transaction message MESSAGE1; assign the called media coding format MRF_SDP1 to the UE2 according to the MESSAGE1; receive the second transaction message MESSAGE2 sent by the CSCF; assign the calling media coding format MRF_SDP2 to the UE1 according to the MESSAGE2; Establish an association relationship between the MRF_SDP1 and the MRF_SDP2. The embodiments of the present invention are used to improve the session success rate between terminals.

The invention relates to an online charging service processing method, a gateway and a system. The method comprises the following steps of: sending a first CCR-U (Credit Control Request-Update) message triggered by a new service of a user to a charging server by a charging gateway; receiving a first CCA-U (Credit Control Answer-Update) message sent by the charging server; carrying out credit control according to a maximum available quota carried by the first CCR-U message and an allowable minimum quota unit; and when the maximum available quota is needed to be reported, sending a second CCR-U message to the charging server, and carrying out credit control according to the second CCR-U message by the charging server. When the minimum quota unit is needed to be reported, waiting for the CCA-U message sent by the charging server is not needed, in addition, the charging server does not need to send the CCA-U message to the charging gateway, and thus, the problem that the real-time property of the system is lowered due to too much message interaction between the charging gateway and the charging server in the traditional charging system is solved, and the condition that the charging system is out of work due to too many CCR / CCA messages is avoided.

The present invention relates to the field of communications. Provided in an embodiment of the present invention are an Ipv4 / Ipv6 double-stack user billing method and device, for reducing the message exchange between BRAS and an existing backstage AAA server, and reducing the impact on the backstage AAA server. The Ipv4 / Ipv6 double-stack user billing method comprises: establishing an Ipv4 connection for an Ipv4 / Ipv6 double-stack user, and generating a billing request packet; establishing an Ipv6 connection for the Ipv4 / Ipv6 double-stack user, generating a billing update packet, and completing the access connection of the pv4 / Ipv6 double-stack user; expanding the existing fields of the billing request packet; summarizing the double-stack information of the billing request packet and the billing update packet, inserting the summarized double-stack information into the expanded billing request packet to form a new billing request packet, and transmitting the new billing request packet. The embodiment of the present invention is used for billing Ipv4 / Ipv6 double-stack users.
