example 1

[0037]Example 1: The network element of the access network determines the data transmission time according to the historical transmission time of the service data. Since the historical transmission time can best reflect the time distribution characteristics of business data transmission, in this preferred embodiment, the data transmission time is determined directly according to the historical transmission time of business data, the determination procedure is simple and the determination result is reliable.

example 2

[0038] Example 2: The network element of the access network receives the transmission time distribution characteristics of the service data from the terminal; the network element of the access network determines the data transmission time according to the transmission time distribution characteristics. Since the terminal can obtain the transmission time distribution characteristics of service data in a timely and accurate manner, the network element of the access network determines the data transmission time according to the transmission time distribution characteristics from the terminal, which can ensure that the data transmission time is closer to the current terminal situation, and then can Ensure efficient transmission of service data between network elements of the access network and terminals.

example 3

[0039] Example 3: The network element of the access network receives the transmission time distribution characteristics of the service data from the core network; the network element of the access network determines the data transmission time according to the transmission time distribution characteristics. Since the core network can store the transmission time distribution characteristics of multiple service data, the network element of the access network determines the data transmission time according to the transmission time distribution characteristics from the core network, which can ensure that in the initial stage of the service initiation by the user (that is, there is no historical transmission Time or past transmission time distribution characteristics) determine the data transmission time, thereby ensuring efficient transmission of service data between the access network element and the terminal.

Abstract

Disclosed are a radio resource scheduling request configuration method and device. The method includes: a network element of an access network determining the data transmission time of service data of a terminal; the network element of the access network configuring an SR resource and an effective time thereof for the terminal according to the data transmission time, wherein the SR resource and the effective time are used for indicating that the terminal is only allowed to use the SR resource to send an SR within the effective time; and the network element of the access network sending to the terminal the configured SR resource and effective time. One aspect of the present invention can ensure that the terminal uses the SR resource to send an SR within the effective time, thus not affecting the throughput of the terminal, nor increasing additional signalling overhead; another aspect can ensure that the SR resource is used by other terminals at other moments instead of within the effective time, thus improving the utilization efficiency of the SR resource.

Description

technical field [0001] The present invention relates to the communication field, in particular to a radio resource scheduling request configuration method and device. Background technique [0002] At present, in the third-generation mobile communication Long Term Evolution (LTE for short) system, when the user equipment (User Equipment, UE for short) and the network side maintain a radio resource control (Radio Resource Control, RRC for short) connection state , the network configures a scheduling request (Scheduling Request, SR for short) resource for the UE. In LTE, the SR is sent on a physical uplink control channel (Physical Uplink Control Channel, PUCCH for short). When the UE has uplink data arriving, and the UE has no available physical uplink shared channel (Physical Uplink Shared Channel, referred to as PUSCH) resources, the UE triggers SR, and the evolved node B (EvolvedNodeB, referred to as eNB) for the UE An SR is sent on the configured SR resource to apply for ...
