  • Patent number: 9402176
    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.

  • Patent number: 8874094
    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.

  • Publication number: 20130279456
    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.
