Description

Method, device and base station for realizing SR processing

Technical Field

The present invention relates to mobile communication technologies, and in particular, to a method, an apparatus, and a base station for implementing SR processing.

Background

Currently, for processing of uplink Scheduling Request (SR) under Discontinuous Reception sleep (DRX sleep) in a Long Term Evolution (LTE) system, generally, the following strategies are adopted: and immediately allocating the uplink authorization after receiving the uplink SR. For a User Equipment (UE) performing discontinuous service processing, it is easy to enter a DRX SLEEP state, and at this time, the base station side easily detects an SR of the UE. Since the SR itself is only an energy impact, and can be detected after passing a threshold, it cannot be determined whether the SR is transmitted by the UE, that is, the SR may be transmitted by the UE or may be detected falsely. Thus, for those cases where the actual UE does not send the SR, i.e. the virtual SR detection, the allocated uplink grant resources are wasted. In addition, since the UE is considered to be in an Active (Active) state after the uplink grant is allocated, at this time, the uplink and downlink may continue to be granted, which may cause more waste.

The above is only considered from the fact that SR authorization wastes one dimension, and if the overall resource limitation of the air interface is considered, the situation may be worse. The base station side needs to process other types of scheduling such as Buffer Status Report (BSR) besides responding to the scheduling of the uplink SR. That is, in a 1 ms Transmission Time Interval (TTI), the base station side needs to process not only the UE of the uplink SR but also the UE of the BSR waiting for scheduling, the number of Resource Block (RB) resources of the air interface is fixed, and the maximum number of scheduled UEs per TTI is also fixed. If the UE of the virtual SR detection occupies the scheduling resource, the UE scheduling with real data will be affected. This situation, if it continues to occur, will certainly seriously affect the system performance.

The above situation is gradually aggravated with the increase of UEs in the system, and the transmission delay of the effective data and the probability of the wasted resources are also gradually increased.

Based on the above consideration, how to fully and efficiently utilize air interface resources and reduce the influence of the virtual detection SR under DRX sleep on the system is an urgent problem under the condition that the LTE air interface resources are limited and TTI scheduling is limited. At present, no technical scheme for inhibiting the virtual detection SR in the DRX sleepS of the LTE system exists.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.

Fig. 1 is a flowchart of a method for implementing SR processing in the present invention, and as shown in fig. 1, for a UE configured with DRX after access, the method includes:

step 100: and adjusting the UE authorization judgment information according to the bearer type established by the UE and the DRX configuration information.

In this step, one mode (simply referred to as mode 1): the UE grant decision information may be a preset grant decision value corresponding to a combination of a bearer type established by the UE and the DRX configuration information. And after the UE establishes the bearer and configures the DRX, searching a corresponding authorization decision value according to the bearer type index and the DRX configuration index. Further, when there are multiple UEs, the largest one of the corresponding grant decision values may be taken as the grant decision value of the UE.

In this step, another mode (simply referred to as mode 2): the value of the grant decision information may also be a grant decision value determined according to a combination of the bearer type established by the UE and the DRX configuration information. Such as: the method comprises the steps that an authorization decision value Q is (Qt multiplied by Cellfactor)/100, wherein Qt is a preset authorization decision value corresponding to a combination of a bearer type established by UE and DRX configuration information; the cell factor is a cell factor, and can be determined comprehensively according to the utilization rate of the current system RB resources and the number of the UE to be scheduled, and the value range is [0,100 ]. This approach can be seen as an improvement of mode 1, since some resources can be wasted in exchange for faster response speed when the cell resource load is low; when the resource load is high, the resources are scarce, and at the moment, the response is carried out after strict classification according to the method of the invention, which is favorable for improving the full utilization of the limited cell resources.

Wherein the authorization decision value is a value greater than or equal to 0.

For example, see: assuming that the UE1 establishes QCI8 bearers after access, the DRX cycle is configured as long cycle 80. In this example, it is assumed that the base station background configures authorization decision information in mode 1, and it is assumed that a preset authorization decision value 18, denoted as Q1, can be retrieved from a preset table through QCI8 and long period 80. The preset table is a two-dimensional array used for storing the authorization decision value corresponding to the combination of the QCI and the period. The following steps are repeated: after accessing the UE2, the QCI8 and the QCI5 are established, and the DRX cycle is configured to be 40, at this time, assuming that the corresponding grant decision values include 18 and 22, 22 is taken as the grant decision value corresponding to the UE2, and is denoted as Q2.

According to this step, when the bearer type or DRX configuration of the UE changes, the corresponding grant decision value is readjusted and updated.

Further, for the UE with the highest priority set in advance or the UE with the high priority defined by the network, the maximum authorization decision value in all the authorization decision values is directly taken as the authorization decision value corresponding to the UE.

Step 101: and carrying out authorization classification on the UE according to the obtained UE authorization judgment information.

The method specifically comprises the following steps: and comparing the obtained UE authorization judgment information with a preset first threshold value and a preset second threshold value, if the obtained UE authorization judgment information is smaller than or equal to the first threshold value, classifying the UE into delay authorization UE, if the obtained UE authorization judgment information is larger than the first threshold value and smaller than or equal to the second threshold value, classifying the UE into confirmation authorization UE, and if the obtained UE authorization judgment information is larger than the second threshold value, classifying the UE into immediate authorization UE. Wherein the content of the first and second substances,

the first threshold value is less than the second threshold value.

The first threshold and the second threshold are set according to an application scenario of the system, for example: for the scenes with few average users and few services, the values of the first threshold value and the second threshold value can be increased as much as possible so as to reduce the user experience time delay; the following steps are repeated: for a scene with a large average number of users or a scene with a large service demand, a first threshold value and a second threshold value can be selected to be lower. And an optimal first threshold value and a second threshold value are given according to a common service scene.

For example, it is assumed that the preconfigured first threshold value T1 is 20, and the second threshold value T2 is 30. Then, in connection with the example in step 100, at this time, the grant decision value Q1< the first threshold value T1, and therefore, the UE1 is classified as a delayed grant UE; the first threshold value T1< grant decision value Q2< second threshold value T2, and thus, UE2 is classified as a confirmed grant UE.

Further, for the UE of the highest priority set in advance or the UE of the high priority defined by the network, the UE is directly classified as the immediate authorized UE.

Step 103: and SR processing is carried out according to the authorization classification.

Fig. 2 is a schematic diagram of SR processing according to authorization classification, and as shown in fig. 2, after determining the authorization classification of the UE according to step 102, this step specifically includes:

for the delayed authorization UE, if the SR is received under the DRX sleep, the received SR is stored, and the authorization processing is carried out when the UE enters a DRX cycle activation time (duration) state.

Such as: the UE1 enters a DRX sleep state, and in the DRX sleep state, if the base station side detects an SR of the UE1, at this time, the SR only needs to be stored, during which the SR of the UE is not detected, until the base station side determines that the UE1 enters the DRX operation state and starts, the stored SR is taken out, and the UE1 is placed in an authorization processing queue to be scheduled;

for the UE confirming authorization, if the SR is received under the DRX sleep, and the SR is continuously received for N times, then authorization processing is carried out; here, N is a preconfigured value, for example, N is 3, is a natural number greater than 0, and has a value range of [1, m ], where m is smaller than the maximum SR transmission number configured by the serving cell. The number N may be determined according to a detection result of a physical layer of the base station, and firstly, depends on a maximum transmission number of a preconfigured SR, and secondly, comprehensively considers a user data delay requirement and the like.

Such as: the UE2 enters a DRX sleep state, under the DRX sleep state, if the base station side detects an SR of the UE2, at the moment, a counter is increased by one, and at the moment, if the accumulated value of the counter is judged to be less than N, the SR is discarded; the test continues next, and if SR is detected, the counter is incremented again until the accumulated value of the counter is N, and the UE2 is placed in the grant processing pending scheduling queue.

For the immediately authorized UE, if the SR is received under DRX sleep, the authorization process is directly entered.

Further, for the preset highest priority UE or the network-defined high priority UE, the authorization process is directly entered.

The direct entry authorization process is: and when the SR is detected, immediately putting the UE into the queue to be scheduled for authorization processing.

According to the method for realizing SR processing, the SR response of the on-line UE under the DRX sleep is controlled, so that the waste of air interface resources caused by SR virtual inspection is greatly reduced, and the SR virtual inspection under the DRX sleep of an LTE system is effectively inhibited. The invention can be adjusted according to the configuration of the UE, thereby ensuring the stability of the system and simultaneously improving the resource utilization rate of the LTE system.
