Example Embodiment

[0037] The basic idea of ​​the present invention is that the UE notifies the E-UTRAN of the user data radio bearer requirement through RRC signaling.

[0038] The implementation of the technical solution will be further described in detail below with reference to the accompanying drawings.

[0039] A method for notifying user data radio bearer requirements, the method comprising: UE notifying E-UTRAN of user data radio bearer requirements through RRC signaling.

[0040] Here, after receiving the user data radio bearer requirement notified by the UE, the E-UTRAN decides whether to forward the data according to the user data radio bearer requirement; if so, forward the data; otherwise, notify the UE to directly transmit the data in the cell where the UE is located. .

[0041] Here, the RRC signaling is specifically the request signaling for the UE to directly transmit data in the cell, and the parameters representing the radio bearer requirements carried in the request signalin...

Abstract

The invention discloses a method for notifying a user data radio bearer requirement. The method comprises the step that: user equipment (UE) notifies an evolved universal terrestrial radio access network (E-UTRAN) of the user data radio bearer requirement through a radio resource control (RRC) signaling. The invention also discloses a system for notifying the user data radio bearer requirement. The system comprises a notification unit on a UE side for the UE to notify the E-UTRAN of the user data radio bearer requirement through the RRC signaling. The method and the system of the invention are used to enable the E-UTRAN to acquire the user data radio bearer requirement of the UE so as to subsequently optimize the transmission of user data by the judgment of the E-UTRAN.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method and system for notifying user data wireless bearer requirements by using radio resource control (RRC) signaling in a long-term evolution (LTE) system. Background technique [0002] At present, the mobile communication system has been developed to LTE. LTE adopts Orthogonal Frequency Division Multiplexing (OFDM), Multiple Input Multiple Output (MIMO) and other technologies, adopts a two-layer structure in the wireless network network, and introduces the evolved home base station (HeNB), including the HeNB LTE structured as figure 1 shown. figure 1 Including: user equipment (UE, User Equipment), enhanced base station (eNB, evelved NodeB), HeNB and core network (EPC, Evolved Packet Core). Among them, the UE can be a mobile phone or a personal computer; the eNB and HeNB are the radio access network (RAN), and the RAN is used to handle all wireless-related fun...
