Description

Method and device for resource allocation under multi-band networking

technical field

The present invention relates to the technical field of wireless communication, in particular to a method and device for resource allocation under multi-band networking.

Background technique

Currently, the three frequency bands assigned to the TDD (Time Division Duplex) system include: F-band 1880-1920MHz, A-band 2010-2025MHz and E-band 2300-2400MHz. In the current TD-SCDMA (Time Division Synchronous Code Division Multiple Access, Time Division Synchronous Code Division Multiple Access) network, the frequency band used is the A frequency band, which is divided into 9 frequency points with a frequency bandwidth of 1.6M. The time slot configurations all adopt the same configuration, such as 2:4. However, with the subsequent development of the business, the F-band and E-band will be gradually used to meet the system capacity requirements.

After introducing multiple frequency bands, the carrier frequency in the cell will include carriers of multiple frequency bands. Wherein, the carrier frequency is managed in a carrier group (that is, a group of carriers capable of power sharing is regarded as a carrier group), and each cell will contain multiple carrier groups belonging to multiple frequency bands.

At present, the time slot allocation method is still that all carriers in a cell adopt a uniform time slot allocation, such as 2:4, and the method of resource allocation is a balanced method, that is, users are allocated to the carrier with the lightest load.

Since there are few types of services in the existing network, and most of them are download services, a unified resource configuration and resource allocation method with a time slot ratio can be adopted. However, with the development of business, the existing resource allocation method and resource allocation method must have the following problems:

1. Due to the use of a unified time slot ratio resource allocation method, the service rate in one direction will be limited or the service rate in both directions will be limited, such as HSUPA (High Speed Uplink Paket Access, high-speed uplink packet access) carrier, the uplink direction can only access services with a maximum rate of 560k;

2. Due to the uniform time slot ratio and balanced resource allocation method, the high-speed services in all directions will be scattered on each carrier. At this time, it is easy to have carriers because after the resources in one direction are full, the other A situation where resources in one direction are unavailable, reducing system capacity. For example, for an HSUPA carrier with a time slot ratio of 2:4, when the uplink accesses 560k services, the downlink resources also become unusable.

In order to make the technical solution of the present invention clearer and clearer, it will be further described below in conjunction with the accompanying drawings.

Detailed ways

The solution of the embodiment of the present invention is mainly as follows: during the initial access and service maintenance process of the user service, according to the symmetry of the service and the preset resource allocation strategy, the user service is allocated or adjusted to match the symmetry of the service. Carrier groups with slot ratios to improve resource utilization and increase system capacity.

As shown in Figure 1, an embodiment of the present invention proposes a method for resource allocation in a multi-band network, including:

Step S101, judging and obtaining the service characteristics of the service when the user service is initially accessed;

Step S102, according to the preset resource allocation strategy, allocate the service on the carrier group with the time slot ratio matching the service characteristics.

Wherein, the resource configuration strategy refers to a strategy in which different frequency bands and different time slot ratios may be used or different carrier groups may adopt different time slot ratios. As shown in FIG. 2 , it is a schematic diagram of resource allocation in multi-band networking. The black in the figure is the occupied time slot. Cell resources are distributed as follows: F-band carrier group 1 includes a DPA carrier with a time slot ratio of 2:4; A-band carrier group 2 includes an R4 carrier with a time slot ratio of 3:3; E-band carrier group 3 includes a time slot The ratio is 4:2 HSUPA carrier.

The aforementioned allocation of different frequency bands and different time slots means that all carriers belonging to the same frequency band in the cell use the same time slot allocation, while carriers belonging to different frequency bands use different time slot allocations.

The aforementioned different carrier groups adopting different time slot ratios means that all carriers belonging to the same carrier group in the cell adopt the same time slot ratio, and carriers belonging to different carrier groups adopt different time slot ratios.

The service characteristics described in this embodiment refer to the characteristics shown by dividing the service according to the attributes of the service. For example, the service can be divided according to the uplink and downlink rates of the service: the service whose uplink rate is greater than the downlink rate is called It is an upload service; the service whose downlink rate is greater than the uplink rate is called a download service.

The above-mentioned allocation of services to the carrier group with a time slot ratio matching the service characteristics refers to selecting the carrier group with the most suitable time slot ratio for the service according to the service characteristics, such as 5:1 and 4: The ratio of uplink and downlink time slots of 2 is suitable for carrying upload services; the ratio of uplink and downlink time slots of 1:5 and 2:4 is suitable for carrying download services.

The service characteristics in this embodiment specifically include service symmetry.

Among them, the symmetry of the service refers to whether the uplink rate of the service is symmetrical to the downlink rate. Specifically, when the difference between the uplink rate and the downlink rate is not large, the service is judged as an uplink and downlink symmetric service; otherwise, it is an uplink and downlink asymmetric service.

Therefore, during the user access process, the service is allocated to the corresponding carrier group according to the symmetry of the service, which means that the most suitable time slot ratio is selected for the service according to the symmetry of the service during the user access process. Carrier groups, for example, users with symmetrical uplink and downlink services can be allocated to carrier groups with a time slot ratio of 3:3; users with asymmetric uplink and downlink services and whose uplink traffic is greater than downlink traffic can be allocated to uplink and downlink time slots On the carrier group with a ratio of 4:2 or 5:1; users whose uplink and downlink services are asymmetrical and whose downlink traffic volume is greater than the uplink traffic volume are allocated to carrier groups with a ratio of uplink and downlink time slots of 2:4 or 1:5 superior.

When the service is initially accessed, the basis for judging the symmetry of the service includes but is not limited to the following:

1. Judging the symmetry of the service according to the RAB symmetry indication (RABAsymmetry Indicator) cell of the RAB parameter in the RAB (Radio Access Bearer, radio access bearer) assignment request (ASSIGNMENT REQUEST) message;

2. Obtain the maximum uplink and downlink rate of the service according to the maximum bit rate cell of the RAB parameter in the RAB allocation request message, and then judge the symmetry of the service according to the ratio of the maximum uplink rate and the maximum downlink rate of the service;

3. According to the guaranteed bit rate cell of the RAB parameter in the RAB request message, the uplink and downlink GBR rate of the service is obtained, and then the symmetry of the service is judged according to the ratio of the uplink GBR rate and the downlink GBR rate of the service;

4. Comprehensively judge the service symmetry according to the RAB symmetry indication cell and the maximum bit rate cell of the RAB parameter in the RAB request message; or

5. The service symmetry is comprehensively judged according to both the RAB symmetry indication cell and the guaranteed bit rate cell in the RAB request message.

The resource allocation method in this embodiment can meet the resource requirements of various services, avoiding the situation that the service rate is limited by the uniform time slot ratio, and improving the user experience; Row symmetry allocates appropriate carrier group resources for users, improves resource utilization, and can effectively increase system capacity.

As shown in FIG. 3, another embodiment of the present invention proposes a method for resource allocation in multi-band networking, including:

On the basis of the foregoing embodiments, before step S101, it also includes:

Step S100, setting a resource allocation policy.

The resource configuration strategy includes a strategy of using different frequency bands and different time slot ratios or using different time slot ratios for different carrier groups.

Also include after step S102:

Step S103, in the process of maintaining the business, judge and obtain the current business characteristics of the business; if the current business characteristics of the business change, go to step S104; otherwise, go to step S105;

Step S104, according to the resource allocation policy, adjust the service to the carrier group matching the current service characteristics.

Step S105, do not adjust the service. That is to say, the service is kept on the current carrier group.

Wherein, the service characteristics are the same as those in the above-mentioned embodiments, including the symmetry of the service. During the business maintenance process, the basis for judging the symmetry of the business includes but is not limited to the following:

1. Judging the symmetry of the service according to the measurement and reporting results of the uplink and downlink 4A or 4B events of the service;

Measure the 4A/4B business volume of the user's uplink and downlink, and the network will report the 4A or 4B event according to the change of the user's current rate, and then judge the symmetry of the user's business according to the 4A or 4B event results reported by the uplink and downlink ;

2. Judging the symmetry of the service according to the ratio of the uplink throughput and the downlink throughput of the service;

Measure the periodic throughput of the user's uplink and downlink delivery to the user plane, and the network side will calculate the user's uplink and downlink service throughput within a period of time, and then judge the user's service according to the ratio of the service's uplink throughput and downlink throughput symmetry.

3. Judging the symmetry of the business according to the event measurement and reporting results of the uplink and downlink throughput of the business;

4. The uplink and downlink 4A or 4B event measurement and reporting results of integrated services and the event measurement and reporting results of uplink and downlink throughput determine the symmetry of the service.

For user uplink and downlink simultaneous delivery of 4A/4B service volume measurement and user plane throughput measurement, the network side can judge the current service symmetry of the user based on the reports of the two measurements.

When the current service characteristics of the service change, the service is adjusted to the carrier group with the corresponding time slot ratio according to the symmetry of the service, that is, the carrier group with the most suitable time slot ratio is selected for the service according to the symmetry of the service during the maintenance process For example, users with symmetrical uplink and downlink services can be allocated to carrier groups with a time slot ratio of 3:3; 4:2 or 5:1 carrier groups; users whose uplink and downlink services are asymmetrical and whose downlink traffic is greater than uplink traffic are allocated to carrier groups with a ratio of uplink and downlink time slots of 2:4 or 1:5.

The technical solution of this embodiment will be described in detail below with specific examples.

Each of the following examples is based on the following carrier group configuration: a carrier group with a time slot ratio of 2:4, a carrier group with a time slot ratio of 4:2, and a carrier group with a time slot ratio of 3:3 are configured in the cell. carrier group.

If the service is bidirectional asymmetric, go to step 16.

12: Allocate users to carrier groups with a time slot ratio of 3:3.

14: Allocate users to carrier groups with a time slot ratio of 2:4.

15: Allocate users to carrier groups with a time slot ratio of 4:2.

16: Determine the uplink and downlink GBR rate of the service obtained from the cell of the RAB parameter in the RAB ASSIGNMENT REQUEST message. If the uplink GBR rate is greater than the downlink GBR rate, perform step 15; otherwise, perform step 14.

17: During the service maintenance process, the periodic measurement of the service volume of the uplink and downlink user planes is delivered;

18: If the periodic measurement times out, the reported uplink and downlink user volume is used to determine whether the symmetry of the service has changed. If it changes, the user is adjusted to the carrier group with the corresponding time slot ratio. Otherwise, the user is not adjusted. See step 19 for the judgment process;

19: Using the reported uplink traffic volume to the reported downlink traffic volume, if the ratio is equal to 1, go to step 110; otherwise, go to step 111;

110: If the user is not currently on the carrier group with a time slot ratio of 3:3, execute step 112; otherwise, execute step 113;

117: Adjust the user to the carrier group with a time slot ratio of 2:4.

Example 2. Resource allocation scheme and business feature discrimination method:

21: When the user initially accesses, the "Maximum Bit Rate" cell of the RAB parameter in the RAB ASSIGNMENT REQUEST message knows the maximum uplink and downlink rate of the service, and judges the user's service symmetry according to the ratio of the maximum uplink and downlink rate. For specific judgments, see step 202 ;

22: Determine the value of the uplink maximum rate compared to the uplink and downlink maximum rate, if the value is 1, go to step 23; if the value is greater than 1, go to step 24; otherwise, go to step 25;

23: Allocate users to carrier groups with a time slot ratio of 3:3;

24: Allocate users to carrier groups with a time slot ratio of 4:2;

If it changes, adjust the user to the carrier group with the corresponding time slot ratio, otherwise, do not adjust the user. The judgment process is as follows: if 4A is reported uplink and 4A is reported downlink or 4B is reported uplink and 4B is reported downlink, perform step 29; if 4A event is reported uplink and 4B event is reported downlink, perform step 210; if 4B event is reported uplink and downlink Report 4A event, go to step 211;

29: If the current user is not on the carrier group with a time slot ratio of 3:3, execute step 212, otherwise, execute step 213;

210: If the current user is not on the carrier group with a time slot ratio of 4:2, then execute step 214, otherwise, execute step 213;

211: If the current user is not on the carrier group with a time slot ratio of 2:4, then execute step 215, otherwise, execute step 213;

212: Adjust the user to a carrier group with a time slot ratio of 3:3;

213: Do not adjust;
