Example Embodiment
[0026] Example 1
[0027] Embodiment 1 of the present invention provides a method for reporting buffer status, including: UE sending buffer status and characteristic information, where the characteristic information is used to indicate that the buffer status corresponds to a VOIP service.
[0028] Further, the characteristic information may be a dedicated logical channel group identification LCG ID, or a logical channel identification LC ID indicating that the buffer status corresponds to the VOIP service.
[0029] In this embodiment, when the UE reports the buffer status, it also provides the service characteristic information corresponding to the buffer status, so that the network node such as the eNB can recognize that the service corresponding to the buffer status is a VOIP service according to the characteristic information, and can Further resources are scheduled for VOIP services to save uplink scheduling signaling and avoid resource waste.
Example Embodiment
[0030] Example 2
[0031] See figure 1 The embodiment of the present invention provides a method for reporting a buffer status, which may include the following steps:
[0032] 101: The eNB receives a service request sent by the UE or the core network, and determines, according to the QCI (Quality Control Indication, quality control indication) in the request, that the service requested by the UE is a VOIP service;
[0033] 102: The eNB configures a dedicated LCG for the VOIP service of the UE, and sends DRB (Data Radio Bearer, Data Radio Bearer) configuration information of the VOIP service, the configuration information includes the identification ID of the dedicated LCG;
[0034] In this step, the eNB informs the UE by sending the LCG ID that the LCG is used to send the buffer status of the VOIP service; correspondingly, after the UE receives the LCG ID, it uses it as an indication of the buffer status corresponding to the VOIP service. In this step, it can be assumed that the LCG I...
Example Embodiment
[0041] Example 3
[0042] Embodiment 3 of the present invention provides a method for reporting the buffer status, which includes: 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 data length of the received VOIP service and the length of the semi-persistent scheduling resource. 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, the UE obtains sufficient transmission resources in time when a large amount of VOIP service data is burst, thereby ensuring timely data transmission, avoiding the loss of VOIP service data, and improving VOIP service quality.
