Description

Scheduling request processing method and device
Technical Field
The present invention relates to the field of mobile communications technologies, and in particular, to a method and an apparatus for processing a scheduling request.
Background
In a Long Term Evolution (LTE) system, when a User Equipment (UE) has uplink data to be transmitted and no uplink resource is available for transmission, the UE may Request an evolved Node B (evolved Node B, eNB) for the uplink resource by sending a Scheduling Request (SR). However, for the eNB, it cannot determine when the UE needs the uplink resource, so the eNB performs SR detection according to a certain period, and if the SR transmitted by the UE is detected, allocates a certain uplink resource to the UE.
Voice over LTE (VoLTE) based on LTE (e.g., wechat phone, QQ phone, etc.) is becoming popular and popular with the rapid development of mobile internet, and it follows that the number of UEs using VoLTE service in LTE cell is rapidly increasing, and further the number of SRs received by eNB is rapidly increasing in the same time, and the processing process of eNB to SR will also face huge challenges.
Currently, an eNB configures a fixed pre-scheduling period and performs an SR process within the configured pre-scheduling period, where a flow of performing the SR process within the configured pre-scheduling period is shown in fig. 1. Fig. 1 shows a flowchart of an SR processing method for a VoLTE service in the prior art, as shown in fig. 1, an eNB determines whether a signal-to-noise ratio of a resource for performing SR detection is greater than a preset signal-to-noise ratio threshold for voice activation detection, determines that SR processing is required if the signal-to-noise ratio of the resource for performing SR detection is greater than the preset signal-to-noise ratio threshold for voice activation detection, further determines whether a UE for performing VoLTE service is in an active period if the signal-to-noise ratio of the resource for performing SR detection is less than the preset signal-to-noise ratio threshold for voice activation detection, determines that SR processing is required if the UE is in the active period, further determines whether a time when the UE does not receive an SR is greater than or equal to a silent period if the UE is not in the active period, and determines that SR processing is required if the UE is in.
With the increase of the number of UEs using VoLTE services in a cell, the number of SRs transmitted by the UEs to the eNB at the same time increases rapidly, and due to the limited processing capability of the eNB, a large number of SR missed detections may result, so that the SR missed detection rate increases, and further the transmission delay of the voice data packet of the UE increases, resulting in poor user experience.

if the UE is determined to be in the silent period, determining the number of times of SR detection according to the silent period of the UE and the determined pre-scheduling period, and
within the determined pre-scheduling period, performing the number of times of SR detection;
and if the SR detection of the times is determined not to pass the voice activation detection, performing one-time SR processing on the UE in the silent period in the determined pre-scheduling period.
7. The apparatus of claim 6, wherein the preset UE number threshold in the mapping relationship is at least two UE number thresholds including a first UE number threshold and a second UE number threshold, a pre-scheduling period corresponding to the first UE number threshold is different from a pre-scheduling period corresponding to the second UE number threshold, the pre-scheduling period corresponding to the first UE number threshold is greater than the pre-scheduling period corresponding to the second UE number threshold, and the first UE number threshold is greater than the second UE number threshold.
8. The apparatus of claim 6, wherein the processing unit determines the number of times to perform the SR detection according to the quiet-period of the UE and the determined pre-scheduling period in the following manner:
determining a ratio between a silent period of the UE and the determined pre-scheduling period as the number of times of SR detection of the UE in the silent period.
9. The apparatus according to any of claims 6 to 8, wherein the statistics unit is further configured to:
according to the determined pre-scheduling period, after SR processing is carried out, the number of UE in a cell covered by an access base station is counted again;
the processing unit is further to:
if the UE number counted again by the counting unit is determined to exceed the selected UE number threshold value, starting wireless link reconfiguration;
and determining a pre-scheduling period according to the counted number of the UE again in the reconfiguration process of the wireless link.
10. The apparatus as recited in claim 6, said processing unit to further:
before the counting unit counts the number of the UE in the cell covered by the access base station, a switch configured in advance and used for controlling the SR processing is started, wherein the SR processing is carried out after the switch is started, and the SR processing is stopped after the switch is closed.
