Example Embodiment

[0050] The basic idea of ​​the present invention is: when it is determined that two user terminals for data transmission are located in the same base station, if the user terminal identification pair that allows direct user data exchange in the base station stored in the base station includes the identification information of the two user terminals , the data of the two user terminals are directly transmitted under the base station without going through the core network, especially the PDCP data for which the user has prepaid the packet data traffic fee, and does not need to pass through the core network. The invention greatly reduces the data transmission pressure of the core network.

[0051] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

Abstract

The invention discloses a method for transmitting packet data convergence protocol data, comprising the following steps of: setting a corresponding local user data loop module for each PDCP (Packet Data Convergence Protocol) entity in a base station, receiving a UE identifier pair allowing direct user data exchange in the base station and issued by a network side and storing the UE identifier by the base station; receiving uplink data of the UE and transmitting the uplink data to the local user data loop module of the UE by the PDCP entity of the UE in the base station; analyzing the uplink data packet by the local user data loop module of the UE and judging whether the uplink data packet accords with the preset strategy, if so, transmitting the uplink data packet to the destination UE directly by the local user data loop module of the UE. The invention also discloses a device for transmitting packet data convergence protocol data. The invention greatly reduces the data transmission pressure of a core net.

Description

technical field [0001] The present invention relates to a packet data convergence protocol (PDCP, Packet Data Convergence Protocol) data transmission technology, in particular to a packet data convergence protocol data transmission method and device in a long term evolution (LTE, Long Term Evolution) system. Background technique [0002] At present, the mobile communication system has been developed to LTE. LTE adopts Orthogonal Frequency Division Multiplexing (OFDM, Orthogonal Frequency Division Multiplexing), Multiple Input Multiple Output (MIMO, Multiple Input Multiple Output) and other technologies. , Home evolved NodeB). figure 1 It is a schematic diagram of the structure of LTE including HeNB, including user terminal (UE, User Equipment), access node (eNB, evelvedNodeB), home access node (HeNB, Home evolved NodeB) and core network (EPC, Evolved Packet Core) . eNB and HeNB constitute a radio access network (RAN, Radio AccessNetwork). RAN is used to handle all wireles...
