Description
Technical Field
The present invention relates to the field of wireless communication technologies, and in particular, to a load balancing method and apparatus.
Background
The problem of Voice transmission in an LTE (Long Term Evolution ) network is often solved by LTE network direct transmission, that is, Voice over LTE (Voice service over LTE) network, and the Voice over LTE network realizes high-quality Voice and video calls carried on the LTE network. With the large-scale commercialization of VoLTE, the number of VoLTE voice service subscribers inevitably goes through a rapid development period and exists on a large scale in the network.
In an LTE system, the maximum number of VoLTE voice service users supported by the system is limited by the scheduling capability and system performance of a single subframe. For the TD-LTE system, the uplink resources are more limited due to the structural configuration with fewer uplink subframes. When the number of voice service users in the same cell reaches a certain number, the quality of the voice service cannot be guaranteed, and therefore load balancing needs to be performed.
At present, a load balancing strategy does not separately consider VoLTE voice service users and cannot completely meet the requirements of the VoLTE voice service users, so that load balancing processing needs to be performed on the voice service users to solve the problems of time delay, packet loss, jitter and the like of voice services caused by the fact that the number of voice service users in the same cell is too large.

fig. 2 is a load balancing apparatus according to an embodiment of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The priority of the voice of the LTE network is higher than that of the 2G/3G network, so in order to maintain the quality of voice service, the balancing strategy in the system is considered first when considering the load balancing of the voice users of the VoLTE.
Referring to fig. 1, a schematic flow chart of a load balancing method according to an embodiment of the present invention is shown, where the flow chart may include the following steps:
step 101: the base station detects the number of voice service users in the source cell.
In VoLTE application, a voice Service user refers to a user who establishes a bearer with a QCI (Quality of Service Class Identifier) of 1.
QCI is a scale value used to measure the packet forwarding behavior, such as packet loss rate, packet delay budget, etc., of a specific Service Data Flow (SDF). Wherein the bearer with QCI ═ 1 is used to service voice calls.
Step 102: the base station judges whether the number of voice service users in the source cell exceeds the voice service user number balance threshold of the source cell. If yes, the step 103 is executed; otherwise, go to step 101.
Because the number of voice service users that can be simultaneously supported by a cell is limited, if the number of voice service users in a cell exceeds a certain number, MOS (Mean Opinion Score) of the voice service users may not be guaranteed, and problems such as delay, packet loss, jitter, and the like of the voice service may occur.
In the international standard, MOS values are used uniformly to evaluate the quality of compressed speech received by the system, where 5 denotes good, 4 denotes good, 3 denotes fair, 2 denotes bad, and 1 denotes bad. If measured from the degree of attention required to hear the speech: 5 indicates that the person can hear the music without attention; 4 indicates that a little attention is required to hear; 3 indicates that a certain attention is required to hear; 2 indicates that considerable attention is required to be barely audible; 1 indicates how attentiveness is difficult to hear.
In order to ensure the voice quality of the voice service users, a voice service user number balance threshold is set for the cell. When the number of voice service users in a cell exceeds the threshold of voice service user number balance, the cell is considered to be unable to ensure the voice quality of the voice service users in the cell, and the voice users need to be subjected to load balance. Optionally, different voice service user number equalization thresholds may be set according to different configurations of different cells, or the same voice service user number equalization threshold may be set for different cells, which is not limited in the present invention.
Step 103: the base station determines the number of voice service users needing to be switched in the source cell and the number of voice service users receivable in the co-coverage adjacent cell of the source cell.
Specifically, the number of voice service users to be switched in the source cell is a difference between the number of voice service users in the source cell and a voice service user number balance threshold of the source cell.
Specifically, the number of voice service users that can be accepted in the co-coverage neighboring cell can be determined by the following method:
and if the voice service user number balance threshold of the common coverage adjacent cell of the source cell is greater than the voice service user number in the common coverage adjacent cell, determining the difference value between the voice service user number balance threshold of the common coverage adjacent cell and the voice service user number in the common coverage adjacent cell as the receivable voice service user number in the common coverage adjacent cell.
If the voice service user number balance threshold of the common coverage adjacent cell of the source cell is less than or equal to the voice service user number in the common coverage adjacent cell, it indicates that the common coverage adjacent cell also needs to perform load balance on the voice service user, and the cut-in of the voice service user of the source cell cannot be accepted, that is, the number of the voice service users that can be accepted in the common coverage adjacent cell is zero.
And determining the number of the voice service users which can be accepted by each co-coverage adjacent cell according to the method.
Step 104: and the base station switches the voice service users needing to be switched in the source cell to the common-coverage adjacent cell of the source cell according to the number of the voice service users needing to be switched in the source cell and the number of the voice service users which can be accepted in the common-coverage adjacent cell of the source cell.
Specifically, in the above step, if the number of voice service users needing to be switched in the source cell is N, the sum of the numbers of voice service users that can be accepted in all the co-coverage neighboring cells of the source cell is M, N and M are integers greater than or equal to 1, and N < ═ M, then all the voice service users needing to be switched in the source cell are switched to the co-coverage neighboring cells of the source cell; if N is larger than M, switching part of users needing to switch the voice service in the source cell to the co-coverage neighbor cell of the source cell, and switching the other part of users needing to switch the voice service to the neighbor cell of the different system.
And if the number M of the receivable voice users in all the co-coverage adjacent cells is zero or the source cell does not have the co-coverage adjacent cells, switching all the users needing to be switched in the source cell to the different-system adjacent cells.
Preferably, the base station switches the voice service user needing to be switched in the source cell to the co-coverage neighboring cell of the source cell according to the number of the voice service users needing to be switched in the source cell and the number of the voice service users receivable in the co-coverage neighboring cell of the source cell, and the specific implementation manner is as follows:
and determining the number of the voice service users of the common coverage adjacent cell which needs to be switched to the source cell in the source cell according to the number of the voice service users which need to be switched in the source cell and the number of the voice service users which can be accepted in the common coverage adjacent cell of the source cell. Here, taking the number of voice service users in the source cell that need to be handed over to the co-coverage neighboring cell of the source cell as K, where K is N in the case of N < ═ M, and K is M in the case of N > M, and then the voice service user handover may be performed according to the coverage condition of the co-coverage neighboring cell of the source cell, which may specifically include the following cases:
case 1: and if the co-coverage adjacent cell of the source cell is the adjacent cell completely co-covered with the source cell, acquiring the voice service user which does not report the A2 measurement report in the source cell. If the number of the voice service users which do not report the A2 measurement report in the source cell is larger than or equal to K, selecting K voice service users from the voice service users which do not report the A2 measurement report to switch to an adjacent cell which is completely covered by the source cell; otherwise, switching all M1 voice service users which do not report the A2 measurement report and other M2 voice service users which report the A2 measurement report in the source cell to a neighboring cell which completely covers the source cell; wherein M1 and M2 are both integers greater than or equal to 1, and M1+ M2 ═ K.
The reporting of the a2 measurement report by the user is triggered by an event, and if the RSRP (Reference Signal Receiving Power) value of the serving cell to which the user is currently connected is smaller than a threshold, the user reports the a2 measurement report.
When the voice service user needing to be switched is switched to the common coverage adjacent cell of the source cell, the voice service user needing to be switched can be switched to the complete common coverage adjacent cell of one or more source cells under the condition that the voice service user number in the common coverage adjacent cell does not exceed the voice service user number balance threshold.
Optionally, the voice service user needing to be switched to the co-coverage neighboring cell of the source cell is switched to the complete co-coverage neighboring cell of the source cell in a blind switching manner. Generally, handover is divided into three phases, i.e., measurement, decision, and execution. The blind handover refers to handover performed without measurement information, that is, without measuring the target cell, as long as the level or quality of the source cell is reduced to a threshold, a handover procedure is started, so as to save measurement time and avoid negative effects caused by the compressed mode.
Case 2: if the common coverage adjacent cell of the source cell is a partial coverage adjacent cell, configuring A4 measurement to K voice service users in the source cell; if the number of voice service users not reporting a2 measurement report in the source cell is M1 and M1 is less than K, a4 measurement is configured for M2 voice service users reporting a2 measurement report, M1 and M2 are integers greater than or equal to 1, and M1+ M2 is equal to K. After receiving an A4 measurement report reported by voice service users needing to be switched, if the number of the voice service users in the current source cell exceeds the voice service user number balance threshold of the source cell, switching the voice service users currently reporting the A4 measurement report to an adjacent cell partially covered with the source cell.
The reporting of the A4 measurement report by the user is triggered by an event, and if the RSRP of the adjacent cell is greater than a threshold value, the user reports the A4 measurement report.
When the voice service user needing to be switched is switched to the common coverage adjacent cell of the source cell, the voice service user needing to be switched can be switched to the partial common coverage adjacent cell of one or more source cells under the condition that the voice service user number in the common coverage adjacent cell does not exceed the voice service user number balance threshold.
Preferably, all voice service users in the source cell are packet-sequenced. All voice service users in the source cell are divided into two groups according to whether A2 measurement reports are reported or not. In each group, voice service users with the same uplink and downlink equivalent PRB (Physical Resource Block) utilization rate are sorted in the sequence from low to high, and voice service users with the same uplink and downlink equivalent PRB utilization rate are randomly sorted. And when the load balance is carried out on the voice service users, the voice service users with low uplink and downlink equivalent PRB utilization rate are preferentially selected. If the voice service user does not report the a2 measurement report, which indicates that the signal quality of the user is better, the signal quality after the user switches to the completely co-covered neighbor cell is also better. Therefore, the voice service users which do not report the A2 measurement report are preferentially switched to the all-co-coverage neighbor cell, and the switching success rate can be ensured. The uplink and downlink equivalent PRB utilization rate is used for reflecting the condition that the user occupies the wireless resources in the system, and the lower the utilization rate is, the less the wireless resources occupied by the user is, the easier the switching process is relatively, so the user with the low utilization rate is preferentially switched.
Specifically, if the number of voice service users not reporting a measurement report of a2 in the source cell is greater than or equal to the number K of voice service users needing to be switched, K voice service users arranged in the front (i.e., having low utilization rate of uplink and downlink equivalent PRBs) are selected from the group not reporting a measurement report of a2 to switch; if the number of the voice service users which do not report the A2 measurement report in the source cell is less than the number of the voice service users which need to be switched, all the M1 voice service users in the group which do not report the A2 measurement report are switched, and then the M2 voice service users which are arranged in the front are selected from the group which report the A2 measurement report to be switched.
In the above embodiment of the present invention, if the number of voice service users in the source cell exceeds the number of voice service users in the source cell equilibrium threshold, the voice service users in the source cell that need to be switched are switched to the co-coverage neighboring cell of the source cell according to the number of voice service users in the source cell that need to be switched and the number of voice service users that can be received in the co-coverage neighboring cell of the source cell, so as to avoid the problems of voice service quality degradation, delay, packet loss, jitter, and the like caused by the excessive number of voice service users in the same cell, thereby affecting user perception.
Based on the same technical concept, the embodiment of the invention also provides a load balancing device which can execute the method embodiment. The apparatus may be a base station, or an apparatus on a base station, which is not limited in this respect.
Referring to fig. 2, which is a schematic structural diagram of a load balancing apparatus provided in an embodiment of the present invention, as shown in the figure, the base station includes: the base station comprises a detection module 201, a determination module 202 and a switching module 203, and further comprises a configuration module 204.
The detection module 201: the method is used for detecting the number of voice service users in the source cell, and if the number of voice service users in the source cell exceeds the voice service user number balance threshold of the source cell, the determining module and the switching module are instructed to execute the operation.

The switching module 203 is configured to switch the voice service user needing to be switched in the source cell to the co-coverage neighboring cell of the source cell according to the number of the voice service users needing to be switched in the source cell and the number of the voice service users that can be received in the co-coverage neighboring cell of the source cell.
A configuration module 204, configured to configure a4 measurement for a voice service user in a source cell when a co-coverage neighboring cell of the source cell is a partial coverage neighboring cell.
In VoLTE applications, a voice service user refers to a user with a bearer having QCI ═ 1 established.
The number of the voice service users to be switched in the source cell is the difference value between the number of the voice service users in the source cell and the number of the voice service users in the source cell.
Specifically, the determining module 202 may determine the number of voice service users that can be received in the co-coverage neighboring cell by the following method:
and if the voice service user number balance threshold of the common coverage adjacent cell of the source cell is larger than the voice service user number in the common coverage adjacent cell, determining the difference value between the voice service user number balance threshold of the common coverage adjacent cell and the voice service user number in the common coverage adjacent cell as the receivable voice service user number in the common coverage adjacent cell.
Specifically, the switching module 203 switches all the voice service users needing to be switched in the source cell to the co-coverage neighboring cell of the source cell when the number of the voice service users needing to be switched in the source cell is N, the number of the voice service users receivable in the co-coverage neighboring cell of the source cell is M, N and M are integers greater than or equal to 1, and N is less than or equal to M; otherwise, if N is larger than M, switching part of the users needing to switch the voice service in the source cell to the co-coverage neighbor cell of the source cell, and switching the other part of the users needing to switch the voice service to the neighbor cell of the different system.
Preferably, when the determining module 202 switches the voice service user, the following specific manner may be implemented:
and determining the number of the voice service users of the common coverage adjacent cell which needs to be switched to the source cell in the source cell according to the number of the voice service users which need to be switched in the source cell and the number of the voice service users which can be accepted in the common coverage adjacent cell of the source cell. Here, taking the number of voice service users in the co-coverage neighboring cell that needs to be handed over to the source cell as K as an example, K ═ N is the case of N < ═ M, and K ═ M is the case of N > M.
Thereafter, the switching module 203 may execute the voice service user switching according to the coverage condition of the co-coverage neighboring cell of the source cell, which may specifically include the following conditions:
case 1: and if the co-coverage adjacent cell of the source cell is the adjacent cell completely co-covered with the source cell, acquiring the voice service user which does not report the A2 measurement report in the source cell. If the number of the voice service users which do not report the A2 measurement report in the source cell is larger than or equal to K, selecting K voice service users from the voice service users which do not report the A2 measurement report to switch to an adjacent cell which is completely covered by the source cell; otherwise, switching all M1 voice service users which do not report the A2 measurement report and other M2 voice service users which report the A2 measurement report in the source cell to a neighboring cell which completely covers the source cell; m1 and M2 are both integers greater than or equal to 1, and M1+ M2 ═ K.
Case 2: if the common coverage neighboring cell of the source cell is a partial coverage neighboring cell, the configuration module 204 configures a4 measurement to K voice service users in the source cell; if the number of voice service users not reporting a2 measurement report in the source cell is M1 and M1 is less than K, a4 measurement is configured for M2 voice service users reporting a2 measurement report, M1 and M2 are integers greater than or equal to 1, and M1+ M2 is equal to K. After receiving the a4 measurement report, if the number of voice service users in the current source cell exceeds the voice service user number balance threshold of the source cell, the switching module 203 switches the voice service users currently reporting the a4 measurement report to the neighboring cell partially covering the source cell.
In the above embodiment of the present invention, if the number of voice service users in the source cell exceeds the number of voice service users in the source cell equilibrium threshold, the voice service users in the source cell that need to be switched are switched to the co-coverage neighboring cell of the source cell according to the number of voice service users in the source cell that need to be switched and the number of voice service users that can be received in the co-coverage neighboring cell of the source cell, so as to avoid the problems of voice service quality degradation, delay, packet loss, jitter, and the like caused by the excessive number of voice service users in the same cell, thereby affecting user perception.
