Abstract: The present invention discloses a method and device for re-initiating EPS session management procedure. The application of technical solution proposed through embodiment of this invention can enable PGW to determine whether handover operation on MME side is completed through timing by timer and/or instruction message on MME side; if it is completed, re-initiate session management process of corresponding EPS system, thus enabling PGW to timely re-initiate EPS session management procedure, reducing the time for unnecessary waiting, and avoiding resource waste caused by repeated rejection of EPS session management procedure re-initiated when handover procedure is not completed, so as to improve reconnection efficiency of session management process of EPS system and reduce waste of communication resource.

Abstract: The invention embodiments disclose a method, system and device for transmitting data, relate to wireless communication technical art, and resolve the question that terminal how to transmit data when packet data network (PDN) connection is not be established. In the invention, when the terminal needs to transmit data and the PDN connection for transmitting the data is not be established, the terminal sends data transmitting message which carries a PDN connection request message and package to be transmitted to mobility management entity (MME). The PDN connection is only established by core network side when the MME receives the data transmitting message, and the package to be transmitted is sent out by the PDN connection. Therefore, the invention enables UE to transmit data when PDN connection is not be established.

Abstract: The present invention puts forward a method, a system and an apparatus for selecting a data plane tunnel according to the status of User Equipment (UE). The system comprises a Serving Gateway (SGW) and a Local Gateway (LGW), wherein, the SGW is used for determining the status of the UE and whether a connection is used for Local IP Access (LIPA)/Selected IP Traffic Offload (SIPTO), and instructs the LGW; the LGW is used for setting a tunnel identifier status of the LGW according to the instruction of the SGW, and selecting the data plane tunnel according to the tunnel identifier status. The present invention selects an appropriate data plane tunnel by setting a tunnel identifier in an LGW, and proposes a method for controlling the to setting/clearing of the tunnel identifier, therefore the present invention enjoys comprehensive functions and may make up the deficiency of LIPA/SIPTO architecture in the prior art.

Abstract: Examples of the present disclosure provide a method and apparatus for managing a PDN connection. In the method, a core network control entity determines that UE enters an idle state, determines a PDN connection corresponding to the UE as a PDN connection of a designated type and cancels the PDN connection of the designated type.

Abstract: An informing method and equipment for index parameter of access type/frequency of selection priority are provided. Said method includes that a Mobility Management Entity (MME) receives the voice capabilities and settings reported by User Equipment (UE) (101); the MME generates a Radio access type/Frequency of Selection Priority (RFSP) index according to the subscribed RFSP index, the voice capabilities and settings reported by said UE, and the operator's configuration policies (102); when the MME determines that said generated RFSP index is different from the RFSP index in use, it replaces the RFSP index in use with said generated RFSP index (104); the MME informs the Radio Access Network (RAN) of said generated RFSP index (105). The present invention overcomes the problem that the transmission of the new RFSP index in use can not be finished under the condition that the UE is in an idle state, the UE has no uplink data, and the MME does not receive the notification of the downlink data.

Abstract: The present application discloses a method and device for updating a tracking area list, which method comprises: determining, by a mobility management entity, whether a tracking area list allocated to a user device has been changed; determining, when the tracking area is changed, whether there is no tunnel management message on an S11 interface; and when there is no tunnel management message, sending, by the mobility management entity, a message to a serving gateway, with the message carrying a changed tracking area list or indication information capable of determining the changed tracking area list. The mobility management entity transfers a tracking area list to the serving gateway only when the tracking area list of the user device changes and can still transfer a new tracking area list to the serving gateway even when there is no tunnel management message on the S11 interface, thereby remedying the defects in the solutions in the prior art.

Abstract: Disclosed are a method, system, and device for establishing a local IP access (LIPA) connection, relating to the technical field of wireless communication, for use in solving the incapability of a user equipment (UE) to establish successfully the LIPA when the UE subscription information lacks therein information of a closed subscriber group (CSG) wherein the UE is established and an access point name (APN) for LIPA allowed by the CSG. In the present invention, when a UE-transmitted connection request is received by a network side, within a correlation between a preconfigured CSG identifier and an APN for public access, an APN corresponding to the identifier of the CSG wherein the UE is established is searched for, and the LIPA is established for the UE when the APN is found, or, the APN found is transmitted to the UE and the UE subscription information is modified. Employment of the present invention allows the UE to perform LIPA successfully.
