The present invention discloses a method for obtaining an Internet protocol header replacement mapping, which belong to the field of communications technologies. The method includes: obtaining, by a network node, fixed IP header information which is bound to a UE, where the network node is an MME or an eNB or a PGW or an SGW; establishing an IP header replacement mapping according to the fixed IP header information, where the IP header replacement mapping is correspondence between the fixed IP header information and an index or a bearer; and performing data transmission with the UE according to the IP header replacement mapping. In the present invention, the network node establishes the IP header replacement mapping according to the obtained fixed IP header information which is bound to the UE, the method is more flexible.

Method for obtaining internet protocol header replacement mapping and network node

A method and an apparatus for identifying a UE in an SAE network, and an MME are provided herein. The method includes: receiving an SAE-TMSI which is allocated to a UE that accesses an SAE network and includes at least: a pool-ID, an MME-ID, and a UE temporary identifier; using the SAE-TMSI to temporarily identify the UE in the SAE network. The apparatus includes: a receiving unit and a temporary identifying unit. The MME includes a temporary identifier allocating unit. Moreover, a method for transmitting and allocating a temporary identifier, and a method for receiving and transmitting information according to the temporary identifier are disclosed herein.

Method and apparatus for identifying user equipment, and method for transmitting and allocating a temporary identifier

A method and device for accessing and obtaining user equipment (UE) context and UE identity are provided. The method for access includes: when a UE accesses a System Architecture Evolution (SAE) network, judging, by a network node, whether a Globally Unique Mobility Management Entity Identifier (GUMMEI) carried by the UE or a Mobility Management Entity Group Identity (MMEGI) in the GUMMEI is allocated or mapped by the SAE network; if the GUMMEI or MMEGI is allocated by the SAE network, selecting, by the network node, a Mobility Management Entity (MME) according to the GUMMEIA network device includes an identity attribute obtaining module and a network resource node allocation module. Therefore, the access of the UE is achieved.

Method and device for accessing and obtaining user equipment context and user equipment identity

A communication method and a device are provided. The method includes: generating, by a first terminal device, first data, where the first data includes second data, the second data includes third data and an identifier of the first terminal device, the second data is data that needs to be reported by the first terminal device to a network device, and the identifier of the first terminal device is used to determine the first terminal device; and sending, by the first terminal device, the first data to a second terminal device when a connection to the network device is not established. Power consumption of the first terminal device can be reduced by using the method and the device in the present disclosure.

Communication method and device

The present invention provides a downlink data transmission method, base station, and serving gateway on an LTE network. The method includes: learning, by an eNB, that a UE needs to be paged, when an S1 bearer is retained and a radio bearer is released; paging, by the eNB, the UE and re-establishing a radio bearer between the eNB and the UE; and sending, by the eNB, downlink data, which is received from an S-GW, to the UE through the re-established radio bearer. Embodiments of the present invention can ensure correct transmission of downlink data, and avoid data loss.

Downlink data transmission method, base station, and serving gateway on LTE network

A service control method for a machine type communications (MTC) device and a related apparatus, where the method includes receiving, by an access-network network element, a paging request message from a core-network network element, wherein the paging request message carries device type indication information of a paged user equipment (UE), determining a device type of the UE according to the device type indication information of the UE, and paging the UE using a dedicated paging resource allocated to an MTC device when the UE is the MTC device.

Service control method for machine type communications device and related apparatus and system

Method and system for setting up a bearer are disclosed. The bearer setup method includes these steps: a packet data network gateway (PGW) obtains first quality of service (QoS) information and a first bearer identifier (ID), and sets up a bearer between the PGW and a radio access network (RAN) according to the first QoS information, where the bearer is associated with the first bearer ID; the RAN sets up a radio bearer (RB) with a user equipment (UE) according to second QoS information associated with the first QoS information, where the RB is associated with a second bearer ID associated with the first bearer ID.

In a method for accessing a legacy wireless network, a radio access network (RAN) node in the legacy wireless network receives an access message sent by a User Equipment (UE) attempting to access the legacy wireless network. The access message includes mobility management entity (MME) information identifying an MME accessed by the UE in an evolved network. The MME information is added by the UE from a temporary identity (ID) allocated by the MME to a first P-Temporary Mobile Station Identity (P-TMSI) in the access message. The RAN node selects a corresponding Serving GPRS Support Node (SGSN) in the legacy wireless network for the UE according to the first P-TMSI in the access message.
