Description
Technical Field

In a communication system, because an uplink signal to interference plus noise ratio SINR of User Equipment (UE) located at an uplink coverage edge of a cell is poor, a channel condition of the UE is poor compared with that of a near-midpoint user, and a signal fading degree is large, when the edge user equipment initiates an uplink service, a phenomenon that the UE cannot be scheduled by a base station in time or a scheduling delay is large easily occurs, which may seriously affect a perception experience of the edge user equipment, and particularly, for an edge voice user with a high priority, the most basic voice experience of the edge user equipment may also be affected thereby.
At present, a Scheduling Request (SR) and a Buffer Status Report (BSR) trigger a base station to perform dynamic Scheduling for a voice service, where a Scheduling response time is relatively long, and an existing Scheduling process is shown in fig. 1. For the UE covering the edge of the cell uplink, in the scenario of edge signal fluctuation, the data upload of the UE is easily limited to the transmission power of the UE and other reasons needing transmission in several segments, for example, in the dynamic scheduling triggered by SR/BSR in fig. 1, it can be assumed that the data of the UE is transmitted in three segments, and then according to the scheduling method shown in fig. 1

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 3 is a schematic flow diagram illustrating a service scheduling method according to an embodiment of the present invention, where the service scheduling method is applied to a network side device, and as shown in fig. 3, the service scheduling method according to the embodiment is as follows.
301. And identifying User Equipment (UE) located at the uplink coverage edge of the cell within the service range of the cell.
It can be understood that, in step 301, the network side device (i.e. the base station) identifies all UEs located at the uplink coverage edge of the cell within the cell service range.
In a specific application, for example, the step 301 may identify all UEs located at the cell uplink coverage edge within the cell service range by determining whether all UEs within the cell service range satisfy a first formula, and if a certain UE within the cell service range satisfies the first formula, identify the UE as a UE located at the cell uplink coverage edge;
wherein the first formula is:
AVG_SINRu+SINRdelta＜SINRth (1)
AVG _ SINRu is the average value of the signal-to-interference-plus-noise ratios SINR in the uplink, SINRdelta is the outer loop adjustment amount of the SINR, and SINRth is a preset threshold value of the SINR. For example, the SINRth may be 3 decibels (dB), which is not limited in this embodiment, and the SINRth may be set according to actual situations.
302. Aiming at any user equipment positioned at the uplink coverage edge of a cell, judging whether the user equipment initiates a scheduling request SR of a voice user or initiates a buffer status report BSR of a voice service.
It can be understood that, in the step 302, if the SR initiated by the user equipment is received and it is determined that the service carried by the SR request includes a voice service, it may be determined that the user equipment initiates the SR of the voice user.
It can be understood that, in the step 302, if the BSR initiated by the ue is received and it is determined that the value of the BSR1 of the current logical channel group is greater than zero, the BSR of the ue initiating the voice service may be determined.
303. If the user equipment is judged to acquire the SR of the voice user or the BSR of the voice service, the scheduling priority of the voice user initiated by the user equipment is improved, and the voice service is actively scheduled for the user equipment according to the adjusted scheduling priority until the scheduling is completed.
It can be understood that the service carried by the SR of the ue-initiated voice user is a voice service, and the BSR of the ue-initiated voice service is substantially the BSR of the ue-initiated voice user.
It can be understood that, for a ue located at an uplink coverage edge of a cell in a high priority service scenario, since a voice packet sent by the ue needs radio link control RLC (radio link control) segmented transmission, in this embodiment, an SR/BSR of a voice user (carrying voice service) is used as a high priority service, in order to ensure the service quality of the voice service, the scheduling priority of the voice user is increased, active scheduling is performed, the priority of uplink service scheduling after the scheduling priority of the voice user is increased is shown in fig. 5, and the priority of uplink service scheduling before adjustment is shown in fig. 4. Compared with the prior art, the method of the embodiment is no longer limited to performing high-priority scheduling on the voice users (carrying the voice services) after the base station receives the BSR, and performs priority ordering on the edge users of the high-priority services according to the service types, and preferentially schedules the high-priority services.
The service scheduling method of this embodiment is applied to a network side device, and determines whether the user equipment initiates a scheduling request SR of a voice user or initiates a buffer status report BSR of a voice service by identifying all user equipments located at a cell uplink coverage edge within a cell service range, and if it is determined that the user equipment initiates the SR of the voice user or initiates the BSR of the voice service, increases a scheduling priority of the voice user initiated by the user equipment, and performs active scheduling of the voice service on the user equipment according to the adjusted scheduling priority until the scheduling is completed, thereby being capable of implementing high-priority service scheduling on the user equipment located at the cell coverage edge, and further being capable of fully utilizing uplink subframes in a marginal signal fluctuation scene, the transmission delay is reduced, the voice quality of the uplink edge user is improved, and the perception experience of the voice service of the uplink edge user equipment is improved.
In a specific application, the step 303 may include steps 303a to 303b not shown in the figure:
303a, if it is determined that the user equipment initiates the SR of the voice user, increasing the scheduling priority of the SR of the voice user initiated by the user equipment, and actively scheduling the voice service for the user equipment by using subsequent continuous uplink subframes according to the adjusted scheduling priority and the preset size of the voice packet to be sent until the scheduling is completed.
It can be understood that, because the voice service data packet has the characteristic of regular transmission, the size of the voice packet in the call period is 200-800 bits, the transmission period is 20ms, and in the case of edge signal fluctuation, for the user equipment located at the cell uplink coverage edge in the high-priority service scenario, since the voice packet sent by the user equipment needs to be transmitted in segments, when the user sends the SR of the voice user, the size of the voice packet to be transmitted can be preset according to the regular transmission characteristics of the voice service data packet, and according to the adjusted scheduling priority, utilizing the subsequent continuous uplink sub-frames to actively schedule the voice service for the user equipment until the scheduling is completed, the time interval from the receiving of the BSR scheduling request to the issuing of the uplink scheduling authorization can be reduced, and therefore the uplink scheduling time delay of the voice service at the uplink coverage edge of the cell can be reduced. For example, if data sent by the ue located at the uplink coverage edge of the cell is transmitted in three segments, the subframe usage of active scheduling by using the method described in this embodiment is shown in fig. 6, where not only the uplink subframe number 17 is fully utilized, but also the data amount can be scheduled and completed in advance by 5ms, the scheduling delay is saved by 5ms, the voice quality of the uplink edge voice user is improved, and the experience perception of the uplink edge voice user is further ensured.
303b, if the BSR of the voice service initiated by the user equipment is judged and known, increasing the scheduling priority of the BSR of the voice service initiated by the user equipment, and actively scheduling the voice service for the user equipment by using subsequent continuous uplink subframes according to the adjusted scheduling priority until the scheduling is completed.
It can be understood that the scheduling priority of the BSR of the voice service initiated by the ue is increased, and the active scheduling of the voice service is performed on the ue by using subsequent consecutive uplink subframes according to the adjusted scheduling priority, so that the uplink subframes can be fully used to reduce the transmission delay.
Further, the step 303a may be further optimized, and the step 303a may specifically include:
predicting the time when the user equipment initiates the SR of the voice user next time according to the historical data of the scheduling request SR of the voice user initiated by the user equipment;
and sending scheduling authorization of the SR of the voice user to the user equipment at the next predicted moment when the user equipment initiates the SR of the voice user next time, and actively scheduling the voice service for the user equipment by utilizing subsequent continuous uplink subframes according to the adjusted scheduling priority and the preset size of the voice packet to be sent until the scheduling is finished.
It can be understood that (the base station) can obtain the rule of the scheduling request SR of the user equipment initiating the voice user according to the characteristic of the regular voice packet of the user equipment initiating the voice user, so as to predict the time when the user equipment initiates the SR of the voice user next time, and can issue the scheduling authorization to the user in advance, thereby reducing the scheduling authorization issue triggered by the SR and shortening the time delay. For example, if data sent by the ue located at the edge of the cell uplink coverage is transmitted in three segments, the subframe usage of the active scheduling performed by the method of this embodiment is shown in fig. 7, where the uplink subframes No. 7 and No. 17 are fully utilized, so that the data amount is scheduled by 10ms in advance, the scheduling delay is saved by 10ms, and the voice quality of the edge user is also improved.
The service scheduling method of the embodiment is applied to network side equipment, and can realize high-priority service scheduling on user equipment located at the coverage edge of a cell, so that an uplink subframe can be fully utilized in an edge signal fluctuation scene, transmission delay is reduced, the voice quality of an uplink edge user is improved, and the perception experience of the voice service of the uplink edge user equipment is improved.

and the scheduling module 83 is configured to, if it is determined that the user equipment initiates the SR of the voice user or the BSR of the voice service, increase the scheduling priority of the voice user initiated by the user equipment, and perform active scheduling of the voice service on the user equipment according to the adjusted scheduling priority until the scheduling is completed.
It should be noted that the network side device in this embodiment is a base station.
The service scheduling apparatus of this embodiment is applied to a network side device, identifies all user equipments located at a cell uplink coverage edge within a cell service range through an identification module, and a determination module determines, for any user equipment located at the cell uplink coverage edge, whether the user equipment initiates a scheduling request SR of a voice user or initiates a buffer status report BSR of a voice service, and if the scheduling module determines that the user equipment initiates the SR of the voice user or initiates the BSR of the voice service, the scheduling module increases a scheduling priority of the voice user initiated by the user equipment, and performs active scheduling of the voice service for the user equipment according to the adjusted scheduling priority until the scheduling is completed, thereby being capable of implementing high-priority service scheduling for the user equipment located at the cell coverage edge so as to fully utilize uplink subframes in a marginal signal fluctuation scene, the transmission delay is reduced, the voice quality of the uplink edge user is improved, and the perception experience of the voice service of the uplink edge user equipment is improved.
In a specific application, for example, the identifying module 81 may identify all UEs located at the cell uplink coverage edge within the cell service range by determining whether all UEs within the cell service range satisfy a first formula, and if a certain UE within the cell service range satisfies the first formula, identify the UE as a UE located at the cell uplink coverage edge;
wherein the first formula is:
AVG_SINRu+SINRdelta＜SINRth (1)
AVG _ SINRu is the average value of the signal-to-interference-plus-noise ratios SINR in the uplink, SINRdelta is the outer loop adjustment amount of the SINR, and SINRth is a preset threshold value of the SINR. For example, the SINRth may be 3 decibels (dB), which is not limited in this embodiment, and the SINRth may be set according to actual situations.
In a specific application, for example, in the determining module 82, if the SR initiated by the user equipment is received and it is determined that the service carried by the SR request includes a voice service, it may be determined that the SR of the voice user is initiated by the user equipment.
In a specific application, for example, in the determining module 82, if the BSR initiated by the ue is received and it is determined that the value of the BSR1 of the current logical channel group is greater than zero, the BSR of the ue initiating the voice service may be determined.
In a specific application, the scheduling module 83 may include a first scheduling unit and a second scheduling unit, which are not shown in the figure:
the first scheduling unit may be configured to, if it is determined that the user equipment initiates the SR of the voice user, increase a scheduling priority of the SR of the voice user initiated by the user equipment, and perform active scheduling of the voice service for the user equipment by using subsequent consecutive uplink subframes according to the adjusted scheduling priority and a preset size of a voice packet to be sent until the scheduling is completed;
the second scheduling unit may be configured to, if it is determined that the BSR of the voice service initiated by the user equipment is known, increase a scheduling priority of the BSR of the voice service initiated by the user equipment, and perform active scheduling of the voice service on the user equipment by using subsequent consecutive uplink subframes according to the adjusted scheduling priority until the scheduling is completed.
It can be understood that, because the voice service data packet has the characteristic of regular transmission, the size of the voice packet in the call period is 200-800 bits, the transmission period is 20ms, and in the case of edge signal fluctuation, for the user equipment located at the cell uplink coverage edge in the high priority service scenario, since the voice packet sent by the user equipment needs to be transmitted in segments, when the user sends the SR of the voice user, the first scheduling unit may preset the size of the voice packet to be sent according to the regular transmission characteristics of the voice service data packet, and according to the adjusted scheduling priority, utilizing the subsequent continuous uplink sub-frames to actively schedule the voice service for the user equipment until the scheduling is completed, the time interval from the receiving of the BSR scheduling request to the issuing of the uplink scheduling authorization can be reduced, and therefore the uplink scheduling time delay of the voice service at the uplink coverage edge of the cell can be reduced. For example, if data sent by the ue located at the uplink coverage edge of the cell is transmitted in three segments, the subframe usage of active scheduling by using the method described in this embodiment is shown in fig. 6, where not only the uplink subframe number 17 is fully utilized, but also the data amount can be scheduled and completed in advance by 5ms, the scheduling delay is saved by 5ms, the voice quality of the uplink edge voice user is improved, and the experience perception of the uplink edge voice user is further ensured.
Further, the second scheduling unit may be specifically configured to
