A method for supporting Multicast Broadcast Multimedia Service (MBMS) data transmission in a Long-term evolution (LTE) system includes a network entity (ECN) to which a user equipment (UE) is registered, receives an Activate MBMS context request message from the UE, and sends a Create MBMS UE Context Request message to a ECN that offers MBMS service. The ECN that offers MBMS service performs an authorization process with a Broadcast and Multicast Service Center (BM-SC) and sends a “Create MBMS UE Context Response” message to the ECN to which the UE is registered. The ECN to which the UE is registered sends an Activate MBMS Context Accept message to the UE. With the methods for supporting the transmission of MBMS data in the LTE system according to present invention, both the BM-SC and the ECN can find the downstream node so that service transmission paths may be found for MBMS data.

The invention discloses an M2M (Machine to Machine) service wireless resource dispatching method based on a TD-SCDMA (Time Division-Synchronous Code Division Multiple Access) network. With the adoption of the designed scheme, M2M communication is supported in the TD-SCDMA network and the frequency of congestion conditions caused by accessing a large quantity of M2M terminals can be reduced. Furthermore, according to the M2M service wireless resource dispatching method provided by the invention, a signal transmission process is simplified, channel transmission data are efficiently used; and H2H (Human to Human) communication is supported in an M2M communication process. The M2M service wireless resource dispatching method is realized by the following steps of: grouping the M2M terminals in a cell by a base station; estimating a total terminal number in the cell by the base station according to a condition of an M2M terminal uplink synchronization process; providing an access channel for a terminal which successfully completes the synchronization process; distributing a transmission channel according to abstract information of each terminal; and supporting the H2H communication in the M2M communication process. The M2M service wireless resource dispatching method provided by the invention is used for providing the data transmission service for a large quantity of M2M terminals in the cell within a specific M2M communication time period aiming at the TD-SCDMA network, so that the use rate of the channel can be improved as far as possible in a condition of reducing the conflict, and the influence on the H2H communication is reduced simultaneously.

The invention relates to a mobile communication technique, which discloses a method for paging users in the mobile communication system to simplify the communication instruction system and reduce the paging time and processing time delay. In said invention, the invention combines the two paging modes as core network and the access network into one mode as access network, to simplify the direct control and management of core network on the user state, to complete relative user mobile state management all in the access network. The paging message can be transmitted via descending shared channel or special paging channel. And when starting the paging, the paging message only contains the user mark.

The invention discloses a method for interacting signaling safely in a session ignition protocol (SIP) registration domain. The registration authentication process is the challenge-based registration authentication process which is defined in the RFC3261, but a digital certificate of the double-key mechanism is adopted in the registration authentication process, therefore, the bidirectional digital-certificate based authentication mechanism is realized, and a shared key SEED used for the non-registration signaling digital abstract authentication is transmitted safely. The non-registration authentication signaling adopts a convenient and efficient digital abstract authentication mode with strong compatibility so that the secure computing expenditure is very little, and the coexistence of high safety and high performance is realized. The invention can prevent the Impersonation attack, the Bye attack, the Cancel attack, the REFER attack, the UPDATE attack and other typical SIP attacks of the server. The invention utilizes the association of the registration authentication and the non-registration authentication and combines the high safety of the double-key authentication and the high efficiency of the digital abstract authentication, thereby having high utility value.

The present invention provides 3 GPP evolution network user equipment attachment method, suitable for mobile communication field, which contains when user equipment user equipment originating attachment request to core network, indicating whether needing calling session control proxy functional entity P- CSCF IP address. The present invention obtains P- CSCF IP address in UE attachment process, after attachment completing UE capable of making IMS registry, for simplifying subscriber service connection establishment signaling process and reducing service connection time delay.

The invention discloses an access method and device in a wireless network. The method comprises the following steps: user equipment sends an access request for multiple cells on multiple access resources; and the user equipment receives feedback information of at least one piece of access equipment in response to the access request to carry out successive access interaction with the access equipment. According to the technical scheme provided by the embodiment of the invention, the multiple access resources are configured, so that the user equipment can initiate the access request for multiple cells on multiple access resources. One random access process is oriented to multiple cells, and multiple random access processes do not need to be separately initiated, thereby simplifying the signaling process, reducing the signaling cost and reducing the access delay.

The invention provides a CS calling method, a CS calling device and user equipment. The CS calling method includes: receiving or transmitting a call request when camping in a new radio system or an LTE system, selecting a traditional cell for camping and accessing when confirming a preferred CS call, wherein the traditional cell supports a CS service, and making a CS call to the network side by using the accessed traditional cell. A smooth CS call can be achieved through the technical solution.

The embodiment of the invention provides a data transmission method and a gateway. The method includes receiving an activate request which at least comprises user an identification used for identifying identification of user equipment and an access point name (APN); and obtaining a gateway address of a gateway of a user contact attribution place, allowing user equipment and the gateway of user contact attribution place to perform data transmission so as to realize each common business. Only one APN is provided, which can reduce the number of APNs, and simplify APN management; a network structure can not be changed and a general APN which needs to go back to the contact attribution place can be flexibly configured; only the attribution place of the APN needs to be analyzed, which can simplify attribution place and reduce requirement to processing capacity of gateway equipment.

The invention discloses a method for maintaining service continuity, which is used for simplifying signaling flow and reducing system load. The method comprises the following steps: a first mobile management entity (MME) in which user equipment (UE) is relocated receives the context information sent by a second MME from which the UE leaves, wherein the context information comprises visitor location register (VLR) identities of the UE; the first MME judges whether a connection is established between the locality and VLRs corresponding to the VLR identities; and if so, the first MME initiates the location updating processes to the VLRs corresponding to the VLR identities via the established connection. The invention also discloses a device for realizing the method.
