Description

Method, device and system for wireless resource allocation and business priority determination

technical field

The invention relates to the field of wireless communication, in particular to a technology for determining service priority in a wireless communication system.

Background technique

In wireless communication networks, such as GPRS (General Packet Radio Service, general wireless packet service), UMTS (Universal Mobile Telecommunications System, universal mobile communication system), WiMAX (World Interoperability for Microwave Access, global microwave access interoperability), The number of wireless communication users is increasing day by day, and communication resources are facing rising load pressure. In particular, user communication needs often have time uncertainty and location uncertainty, so that wireless communication network resources limited by construction and maintenance costs may carry sudden overload user communication needs, resulting in a shortage of wireless communication resources.

In order to improve the efficiency of the use of air interface wireless resources and the service quality of the carried business, emerging wireless technologies, such as WCDMA (Wideband Code Division Multiple Access, wideband code division multiple access), TD-SCDMA (Time Division Synchronous Code Division Multiple Access, Time division synchronous code division multiple access), etc., provides a QoS (Quality of Service, quality of service) mechanism. When resources are limited, RRM (Radio Resource Management, Radio Resource Management) mechanisms such as admission control and congestion control are used to differentiate services and users, so as to meet the needs of more types of services when sharing wireless resources. Constrained resources are fully utilized.

The usual radio resource management mechanism is: in the case of shortage of wireless communication resources, determine the radio bearer priority according to the service priority used by the user (usually the service priority is determined by the service type) and the user level (ie user priority); Allocate wireless communication resources according to the radio bearer priority. When users have the same user priority but use different service priorities, the user with a higher service priority has a higher radio bearer priority, and more preferentially allocates resources.

In the prior art, the method for determining service priority is generally to determine different service priorities for different types of services according to a predetermined service priority policy. For example, according to the service priority policy that the service quality requirement of the voice service is higher than that of the data service, it is determined that the service priority of the voice service is higher than that of the data service.

The inventors of the present application found that with the rapid growth of wireless communication users and new services, mobile users have very different service requirements for wireless resources in different regions or in different time periods. For example, there are two kinds of services, A and B. Because the B service occupies a large amount of wireless resources and has high service operating income, the priority of the B service determined according to the service priority policy is higher than that of the A service. In the actual operation of a wireless communication network, the number of users using service A suddenly increases in a certain period of time in a certain area; although for a single service, service B, which occupies a large amount of wireless If there is a sufficient amount of A business, the radio resource utilization rate and operating income of A business will be higher when occupying the same amount of wireless resources, so the preset service priority (B service priority is higher than A service priority ) to allocate wireless resources is very unreasonable.

Detailed ways

The embodiment of the present invention provides a method for adaptively adjusting service priorities according to changes in service requirements in different regions and in different time periods. Although business requirements will change in different regions and in different time periods, long-term observations show that the changes in various business requirements in the same region are cyclical. For example, for a certain community, there will be many staff coming to work during the period from 9:00 am to 5:00 pm, so the demand for voice services will increase greatly; The voice service demand decreases sharply; the voice service demand of the community will be very little on weekends. It can be seen from this that the service demand of the community changes regularly within a day, and the service demand of the community changes regularly within a week. Of course, there may also be a certain pattern in the change of the service demand of the community within a month, or a quarter, or within a year. Since the change of the service demand is cyclical, the change period of the service demand can be obtained through observation or experience. For example, the change period of the service demand of a certain community is one day or one week. According to the change period of the service demand of the community, count the service demand of different periods in the change period; determine the service priority of different periods according to the service demand of different periods in the change period, then in the next change period (for example, the next day) Or the corresponding period in the second week) can improve wireless resource utilization and operating income by adopting the service priority of the corresponding period, so as to realize the adaptive adjustment of service priority according to the change of service demand in different regions and different time periods , and allocate wireless resources according to the adjusted service priority.

The specific technical solutions will be described in detail below in conjunction with the accompanying drawings.

In the system shown in Figure 1a, it includes: a network management system 101, a priority control server (PCS, Priority Control Server) 102, each base station cell 103 in the wireless access network, and a resource management device 104.

The network management system 101 periodically collects and obtains service demand information of the base station cell 103 in the wireless access network. The service requirement information may include the number of call initiations or the occupation time of the wireless channel for this service.

The priority control server 102 determines the priority of services in the base station cell according to the service demand information of the base station cell obtained by the network management system 101 .

Specifically, it can be determined by determining the service demand of each period in the service demand change period of the base station cell; and according to the service demand of each period, determine the service priority of each period in the change period of the base station cell. Business priority can also be determined by combining the demand of each business and business policy parameters.

Those skilled in the art can set the change cycle and different time periods within the change cycle based on actual experience. For example, the change cycle can be set to 1 day, or 1 week, etc.; for the change cycle of 1 day, each time period can be set to 0:00-8:00, 8:00-12:00, 12:00-14 :00, 14:00-18:00, 18:00-24:00; or for a one-week change period, the time period can be set as: Week 1-Week 5, Week 6-Sunday.

The priority control server 102 sends the determined service priorities of each time period in the change cycle of the base station cell to the network management system 101, and the network management system 101 sends the service priority of each time period in the change cycle of the base station cell to the resource management device 104.

The resource management device 104 is a network element with a resource management function, such as a BSC in the GSM system or an RNC in the UMTS system.

The resource management device 104 uses the service priority of the corresponding period in the corresponding period of the change period to allocate radio resources according to the service priority of each period in the change period of the base station cell.

It should be pointed out here that the service priority determined by the priority control server 102 at each time period in the change cycle of the base station cell can be determined for a single base station cell or for multiple base station cells.

For example, if there is a large difference in the change rule of service demand between base station cells, the priority control server 102 can determine the service priority of each time period in the service demand change cycle of the base station cell for each base station cell; and the resource management device 104 can The radio resources may be allocated to each time period in each base station cell change cycle according to the service priority of each time period in the service demand change cycle of each base station cell.

In order to improve efficiency, when the service requirements of multiple base station cells change in the same or similar pattern, a set of business priorities for each time period in the service demand change cycle can be determined for these multiple base station cells; the resource management device 104 can use this set The service priority of each time period in the service demand change cycle is to allocate radio resources for the multiple base station cells in each time period in the service demand change cycle.

The above-mentioned priority control server 102 can be set in the network management system 101, and obtain the service demand information of the base station cell from the network management system 101 through a local area network or an internal interface; The time slot business priority is sent to the resource management device 104 .

The priority control server 102 can also be installed in a network element (resource management device 104) with network resource management functions, as shown in Figure 1b, regularly obtains the service demand information of the base station cell from the network management system through the IP private network, and passes through the local area network , or the internal interface sends the service priority of each period in the service demand change cycle of the base station cell to the resource management device 104 .

The priority control server 102 can also be an independent network element (as shown in FIG. 1c ), and interacts with the network management system 101 and the resource management device 104 respectively through the IP private network.

The present invention provides two specific embodiments for the method for the priority control server to determine the service priority of each period in the service demand change cycle. The technical solution of the first embodiment is to count the business demand of each time period in the cell change cycle of the base station, and determine the service priority of each time period according to the business demand of each time period; the second embodiment is implemented on the basis of the technical solution of the first embodiment Dynamic updates on business priorities. The technical solutions of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

Embodiment one

Embodiment 1 of the present invention provides a flow chart of a specific method for the priority control server to determine the service priority of each time period in the cell change cycle of the base station, as shown in FIG. 2 , including the following steps:

S201: Obtain service demand information of a base station cell from a network management system.

The network management system regularly collects service demand information from the base station cell, and the priority control server can obtain the service demand information of the base station cell within a set period from the network management system. Those skilled in the art can determine the length of the setting period according to the actual situation. Usually, the setting period should be at least greater than one business demand change cycle, and of course it can also include multiple business demand change cycles, such as 3 days or 5 weeks or 3 months. wait.

S202: According to the service demand information of the base station cell, determine the service demand of various services in different periods in the service demand change cycle of the base station cell.

Divide the service demand change cycle into T periods, and determine the service demand of various services in different time periods in the base station cell service demand change cycle according to the obtained service demand information of the base station cell. For example, after obtaining the service demand information of a base station cell in a service demand change period, the service demand quantities of various services in these different time periods are respectively determined for different set time periods. Those skilled in the art can decide according to the actual situation how much the business demand is determined according to the business demand information, such as setting the business demand as an integer multiple of the number of calls, for example, for the business demand change cycle is 1 day, at 8:00 - If the number of call originations of a certain service in the 12:00 time period is 200, then it is determined that the service demand of this kind of service in the 8:00-12:00 time period of the service demand change cycle is 200.

Of course, if the service demand of the base station cell in each period of the service demand change cycle is counted based on the service demand information in multiple service demand change cycles, the impact of abrupt network data on the statistical results can be avoided. For example, the service demand can be determined according to the service demand information for different periods in multiple service demand change cycles, and then the average value of the service demand in the same period in multiple service demand change cycles can be calculated as the service demand change cycle of the base station cell The business demand in this period.

S203: Determine the service priority of each period in the demand change period according to the various service demands in each period in the service demand change period of the base station cell.

Due to the periodicity of business demand changes, according to the various business demand quantities in each period of the base station cell service demand change cycle determined by previous statistics, the various service demand quantities in each time period in the future base station cell service demand change cycle can be inferred The change of the service demand of the base station cell is obtained, so that on the basis of the original determination of service priority only according to the service type, the change of the service demand in the determined service demand change period can also be used in the subsequent business Adaptively adjust business priorities during demand change cycles. That is, it is equivalent to predicting the service demand in the subsequent base station cell service demand change cycle according to the service demand in the previous base station cell service demand change cycle. Of course, this prediction will not be exactly the same, but it will be close.

In this way, the service priority of each service in each period in the subsequent service demand change cycle can be determined with reference to the service type of each service and the predicted demand of the service during this period of time. Those skilled in the art can determine the business type and the weight of the business demand in determining the business priority according to the actual situation (such as adjusting the weight according to the principle of maximizing revenue), for example, as shown in formula 1:

Z＝m1*X+m2*Y (1)

Among them, Z is the priority of a certain business; X is the business demand of this kind of business; Y is the business type parameter used to characterize this kind of business, because the size of this parameter depends on the strategy of determining the priority according to the type, so It can also be called a business policy parameter; m1 is the weight factor of X; m2 is the weight factor of Y. Those skilled in the art can determine the values of the weight factors m1 and m2 according to the actual situation, so as to adjust the business priority determination strategy. The service policy parameter Y may be determined according to the service type of the service and by comprehensively considering various factors. For example, the service charge of this type of service, the consumption of service resources, or some current dynamics of this type of service: for example, if the operator hopes to focus on promoting this type of service in the near future, it can increase the dynamic parameters of this type of service, so that The policy parameters of this type of service are increased, thereby increasing the priority of this type of service accordingly.

Of course, in the business policy parameters, business resource consumption or business dynamic parameters are not necessary; however, including business resource consumption in business policy parameters can enable technical personnel to adjust business priorities according to business resource consumption; and business policy Including the dynamic parameter in the parameter can make the technician adjust the priority of the service according to the current dynamic situation of the service. For example, a method for calculating service priority by comprehensively considering service demand, service charges, service resource consumption, and service dynamic parameters, as shown in formula 2:

Z＝w1*X+w2*Y1+w3*Y2+w4*Y3(2)

Among them, X is the service demand of a certain service statistics, Y1 is the service fee parameter of the service, Y2 is the service resource consumption parameter of the service, Y3 is the service dynamic parameter of the service; w1, w2, w3 and w4 are respectively Weighting factors for X, Y1, Y2, Y3.

In addition, if a new type of business is added, but there is no demand record for this type of business in the business demand information obtained from the network management system, the set default value will be used as the priority of the business; Configure when adding new business.

S204: After determining the service priority of each time period in the service demand change cycle, the priority control server sends the service priority of each time period in the service demand change cycle of the base station cell to the resource management device.

If the priority control server is set in the network management system, the service priority of each period in the service demand change cycle of the base station cell can be sent to the network management system first, and then sent to the resource management device by the network management system.

If the priority control server is set in a network element (resource management device) with network resource management function, the resource management device can directly obtain the service priority of each period in the service demand change cycle of the base station cell from the priority control server.

S205: The resource management device monitors the arrival of each time period in the service demand change cycle after obtaining the service priority of each time period in the service demand change cycle of the base station cell.

S206: When the resource management device detects the arrival of a certain time period in the service demand change cycle, it takes the service priority of this time period as the current priority.

For example, the service demand change period is 1 day, and when the monitoring time is 8:00, the service priority of various services in the time period of 8:00-12:00 is taken as the current service priority of various services.

S207: The resource management device allocates radio resources to users accessing the cell of the base station according to the current service priority.

In the current period, the radio bearer priority is determined according to the determined current service priority; and the radio resources of users accessing the cell of the base station are allocated according to the radio bearer priority.

The business priority determination sub-module 3022 can determine the priority of each business directly according to the business demand, or can determine the priority of each business in combination with the business demand and business policy parameters. For the specific method of determining the priority, refer to the subsequent description of Figure 5 .

If the priority control server is not set in the same physical entity as the resource management device, the priority control server needs to send the determined service priority information to the resource management device through the LAN or IP private network, so the priority control server also includes:

The service priority sending module 303 is configured to send the service priority information of various services in the base station cell determined by the service priority determining module 302 to the resource management device.

The internal structure of a resource management device provided by Embodiment 1 of the present invention is shown in FIG. 4 , including: a service priority obtaining module 401 and a resource allocation module 402 .

In addition, since the business priority is determined according to the business resource consumption in the business policy parameters in addition to the business demand, it is possible for technicians to adjust the business priority according to the business resource consumption; or according to the business dynamics in the business policy parameters The parameters determine the priority of the business, and also enable technicians to adjust the priority of the business according to the current dynamic situation of the business.

Embodiment two

Embodiment 2 of the present invention provides a method for dynamically updating the service priority in each service demand change period of a base station cell. The flow chart is shown in FIG. 5 , and specifically includes the following steps:

S501: Perform regular monitoring according to a preset service demand change cycle.

For example, monitoring the arrival time of the business demand change cycle can also monitor the arrival time of each segment in the business demand change cycle.

S502: When the periodic timing is up, obtain service demand information of the base station cell in the service demand change period from the network management system.

For the solution of monitoring each time period of the service demand change cycle, the service demand information of the base station cell in the corresponding time period within the service demand change cycle is obtained from the network management system.

S503: According to the obtained service demand information, predict the reference service demand of the base station cell in each time period in the next service demand change cycle.

It can be based on the business demand information in this service demand change cycle to calculate the demand of the service in a certain period of time as Z _P , so as to predict the reference service demand K of the base station cell in the corresponding period of time in the next service demand change cycle _P+1 is: K _P+1 = Z _P ;

It can also be based on the business demand information of each time period in this business demand change cycle and the calculated business demand in each time period of the previous service demand change cycle, predicting the reference business demand of the base station cell in each time period in the next business demand change cycle quantity:

Due to the sudden change of network statistical data, for example, for a certain time period of a day, there is a sudden high demand for a certain service that is higher than that of other days, which shows that the number of calls for this service increases sharply, but after this period, Return to the normal level, but the service priority determination for this period lags behind this period, and the service priority determined according to the service demand of this period may have a negative impact on the radio resource allocation in the subsequent service demand change cycle. In order to solve the above problems, the time series iteration method can be used, that is, to set weights for the data in the past period and the latest data at present, and to take the relative compromise value by considering the data in the past and the data after the current change at the same time.

Assuming that according to the latest business demand change cycle, the actual business demand of this kind of business in the H period in the P cycle is calculated as Z _P according to the statistics of a certain business demand information in the H period in the Pth cycle; and according to For the business demand information in the cycle before the Pth cycle, the reference business demand of this kind of business in the H period in the Pth cycle predicted and calculated is K _P ; The reference business demand of this type of business is K _P-1 ; and so on, take the reference business demand of this type of business in the H period of the previous N cycles, and set the weight of each cycle as W _k , W _k-1 , ...; Then predict and calculate the next business demand change cycle, the reference business demand K P ₊₁ value of this kind of business in the H period in the P+1th cycle is:

K _P+1 ＝∑ _i＝1～N W _ki ×K _Pi +W _k ×Z _P (2)

Among them, i is a natural number, and N is a set constant.
