Embodiment 1

[0027] Embodiment 1 of the present invention provides a method for reporting buffer status, including: UE sending buffer status and characteristic information, wherein the characteristic information is used to indicate that the buffer status corresponds to VOIP service.

[0028] Further, the characteristic information may be a dedicated logical channel group identifier LCG ID indicating that the buffer state corresponds to the VOIP service, or a logical channel identifier LC ID.

[0029] In this embodiment, when the UE reports the buffer state, it also provides the service characteristic information corresponding to the buffer state, so that the network node such as eNB can identify the service corresponding to the buffer state as a VOIP service according to the characteristic information, and can Further perform resource scheduling for VOIP services, save uplink scheduling signaling, and avoid resource waste.

Embodiment 2

[0031] see figure 1 , the embodiment of the present invention provides a method for reporting buffer status, which may include the following steps:

[0032] 101: The eNB receives the service request sent by the UE or the core network, and determines that the service requested by the UE to be transmitted is a VOIP service according to the QCI (Quality Control Indication, Quality Control Indication) in the request;

[0033] 102: The eNB configures a dedicated LCG for the UE's VOIP service, and sends DRB (Data Radio Bearer, Data Radio Bearer) configuration information for the VOIP service, where the configuration information includes the identification ID of the dedicated LCG;

[0034] In this step, the eNB notifies the UE by sending the LCG ID: the LCG is used to send the buffer state of the VOIP service; correspondingly, after receiving the LCG ID, the UE takes it as an indication that the buffer state corresponds to the VOIP service. In this step, it may be assumed that the L...

Embodiment 3

[0042] Embodiment 3 of the present invention provides a method for reporting the buffer status, including: sending the buffer status when the data length of the VOIP service arriving in the buffer reaches the length of the semi-static scheduling resource.

[0043] Further, the UE may calculate the difference between the received VOIP service data length and the length of the semi-persistent scheduling resource, and if the difference is greater than a preset threshold, the UE sends the buffer status, where the preset threshold may be greater than or equal to 0 .

[0044] In this embodiment, when a large amount of VOIP service data bursts, the UE acquires sufficient transmission resources in time, thereby ensuring timely data transmission, avoiding loss of VOIP service data, and improving VOIP service quality.

Abstract

The embodiment of the invention discloses a method, equipment and a system for reporting a buffer zone state, which belong to the field of communication. The method comprises the step of sending the buffer zone state and characteristic information, wherein the characteristic information is used for making the buffer zone state correspond to VOIP services. The equipment comprises a sending module. The system comprises a user terminal and a network node. In the embodiment of the invention, the network node can differentiate the buffer zone states of the VOIP services by supplying the characteristic information of the VOIP services of the buffer zone state to the network node, so the semi-static resource can be scheduled according to the VOIP services, the uplink scheduling signaling is saved and the resource waste is avoided.

Description

technical field [0001] The invention relates to the field of communications, in particular to a method, device and system for reporting buffer state. Background technique [0002] In the evolution to the LTE (LTE, Long Term Evolution, long-term evolution) system, the user terminal (User Equipment, UE) reports uplink scheduling information to a network node such as an eNB (Evolution NodeB, evolved network node B) during the resource scheduling process , including a buffer status report (Buffer Status Report, BSR), used to request the network node to allocate radio resources for the current service. [0003] The BSR of the VOIP service sent by the UE is reported according to a logical channel group (Logical Channel Group, LCG), and the logical channel (Logical Channel, LC) of the service can be divided into the LCG according to the priority. Specifically, if the uplink data of only one LCG triggers the BSR, the UE reports a Short BSR (short BSR) to the network node. The Short...
