Data transmission method and apparatus, and network system

Abstract

The embodiment of the invention provides a data transmission method and apparatus, and a network system, and relates to the technical field of communication. The following problem in the prior art issolved: in a communication system adopting the dual-connection technology, when UE transmits service data, a communication connection always needs to be established between a primary base station anda secondary base station, which increases the power consumption of the UE, thus shortening the standby time of the UE. The method comprises the following steps: when it is determined that the UE is ina power control adjustment period T1 according to a system message, the UE obtains a first air interface signalling message sent by the primary base station; the UE determines an anchor base stationthat receives the uplink data of predetermined service within the power control adjustment period T1 according to a service category of the predetermined service and the first air interface signallingmessage, and sends a second air interface signalling message to the anchor base station; and the UE determines target transmitting power P1 according to an RSRP mean and a third air interface signalling message, and sends the uplink data of the predetermined service to the anchor base station at the target transmitting power P1. The data transmission method and apparatus provided by the embodiment of the invention are used for manufacturing UE and base stations.

Description

technical field

[0001] The present invention relates to the technical field of communication, in particular to a data transmission method, device and network system. Background technique

[0002] In the mobile communication system, in order to improve the system throughput, dual connectivity (English full name: DualConnectivity, abbreviated: DC) technology is introduced to support user equipment in the radio resource control (English full name: Radio ResourceControl, abbreviated: RRC) connection state. (English full name: User Equipment, abbreviated as: UE) simultaneously uses wireless resources provided by two base stations, and the two base stations can be connected through non-ideal transmission.

[0003] Such as figure 1 As shown, in a communication system using dual connectivity technology, the UE maintains a connection with the main base station (full name in English: MastereNodeB, MeNB for short) and the secondary base station (full name in English: Secondary eNodeB,...
