In addition to the IMT-Band system, the use of certain frequency bands in the TV band is reduced, and thus some of the spectrum resources can be borrowed by wireless communication. These TV White Space (TVWS) can be applied to a wide range of wireless communications. It can also be applied to short-distance communication.

At present, the measurement statistics of the above performance are basically completed by the loading of the background staff, and the statistical utilization of resources is also delayed.

In practical applications, for cognitive radio systems, performance measurements as shown in Figure 1 can be performed:

The network side sends performance measurement configuration information to the base station when the resource is reconfigured, and instructs the base station to perform measurement data reporting;

The network side receives the resource reconfiguration result fed back by the base station, performs performance statistics, and optimizes the reconfiguration decision. The network side refers to the network management side (such as EMS, NMS), or the reconfiguration management system (RMS) dedicated to resource reconfiguration. The reconfiguration management system refers to a system module dedicated to management resource reconfiguration in a cognitive radio system, which can be integrated into a network management system. The side is a physical entity that is independently set and has an independent interaction interface with the network management side and the access network side. The performance measurement configuration information is used to perform measurement and counting statistics on the resource reconfiguration result and the reconfiguration status of the base station in the resource reconfiguration process. The specific performance measurement count includes at least one of the following: increasing the number of successes of the carrier, increasing the number of failures of the carrier, the number of times the carrier is activated, the number of times the carrier is deactivated, the number of times the carrier is successfully deleted, the number of failed carrier deletions, and the activated hardware resources. Number of times, number of hardware resources to be deactivated, number of hardware resources added (such as radio frequency unit, baseband processing resource), number of successful spectrum reforming, number of spectrum reforming failures, number of spectrum reforming resources (physical resource module (Physical resource module) Resource Block, PRB);), the number of times the FDD service is re-allocated as TDD/the number of resources, and the number of times the TDD service is re-allocated as FDD/resources, re-allocated as TDD according to the QoS Class Indicator (QCI) level. / number of FDD/resources (such as the number of times that QCI2 is reconfigured by FDD to TDD/number of resources), and the number of reconfigurations of time slots in TDD mode.

The resource reconfiguration result refers to the resource status of the reconfiguration of the base station and the success or failure of the reconfiguration. Including at least one of: adding (or deleting) carrier success/failure (or number of times), activating (or deactivating) carrier success/failure (or number of times), spectrum reforming success/failure (or number of times), spectrum reforming Number of resources, number of resources reconfigured between FDD/TDD, number of slots re-matched by TDD.

The performance statistics include at least one of the following: increasing the success rate of the carrier, deleting the success rate of the carrier, increasing the utilization of the hardware resources, the success rate of the spectrum reforming, the resource rate of the spectrum reforming, and the FDD/TDD mode different QCI Resource re-allocation rate.

The optimized reconfiguration decision refers to the network reconfiguration policy of the network side according to the performance statistics result, including at least one of the following: replacing the added or deleted carrier, adjusting the frequency band of the spectrum reforming, the bandwidth, and the weight in the TDD mode. The ratio of time slots, service reconfiguration between FDD and TDD.

Specifically, when performing radio resource optimization performance measurement, the process shown in FIG. 2 may be performed, where the LTE system is taken as an example, and other systems (such as GSM, UMTS) have performance measurement for radio resource optimization. A similar process. First, the network management side EMS monitors the resource utilization and service allocation of the base station, such as the traffic channel utilization statistics (for example, the number of PRBs occupied by the QCI2 downlink service accounts for more than 70% of the number of available PRBs on the downlink traffic channel), and the carrier resource statistics of the cell (such as Carrier utilization exceeds 95%) and system resource statistics (such as hardware memory utilization exceeds 85%). It is found that the current cell load is overloaded and new resources need to be allocated. The NMS side NMS makes a reconfiguration decision to add a new carrier to the base station. If the base station stores an available carrier, the reconfiguration decision is to activate the carrier. The network management side sends a carrier reconfiguration command to the base station by using the southbound interface, where the increased carrier reconfiguration command includes an increased carrier (such as frequency point fl) or an activated carrier, a carrier bandwidth (number of PRBs), and a base station for resource reconfiguration. /cell identity (eg cell 1).

Or; the NMS detects that the traffic channel utilization statistics of the base station are low (for example, the number of PRBs occupied by the QCI1 downlink service accounts for less than 30% of the number of available PRBs on the downlink traffic channel), the current cell load is low, and the service is small, and the base station can delete part of the carrier. To save resources. The network management side deletes the reconfiguration decision of the base station carrier, and sends a delete carrier reconfiguration command to the base station. The delete carrier reconfiguration command includes a carrier to be deactivated, a carrier bandwidth, and a base station/cell identifier for resource reconfiguration.

Next, the network management side loads the performance measurement configuration information about the resource optimization to the base station, where the performance measurement configuration information is used to perform measurement and counting statistics on the reconfiguration result and the reconfiguration status in the radio resource optimization process, and specifically includes at least one of the following : Increase the number of successful carriers, increase the number of carrier failures, the number of times the carrier is activated, the number of times the carrier is deactivated, the number of successful carrier deletions, the number of failed carrier deletions, the number of activated hardware resources, the number of activated hardware resources, and the number of activated hardware resources. The number of hardware resources. The increased number of hardware resources includes a radio unit (Radio Unit) and/or a baseband unit (Base Band Unit).

When the resource reconfiguration occurs, the base station feeds back the result of the resource reconfiguration to the network management side according to the configuration in the performance measurement configuration information. If the base station increases the carrier success, the feedback increases the carrier success indication to the network management side. If the base station coexists, the carrier fails to be added. If the added carrier interferes with the carrier used by the neighboring cell or the neighboring system, the base station feedback increases the carrier failure indication to the network management. side. For the operation of deleting the carrier, if the operation is successful, the feedback of the carrier is successfully returned to the network management side. The failure to delete the carrier operation fails due to the failure of the terminal to be deactivated.

For activation/deactivation operations (including carrier resources, hardware resources), the feedback process is similar to the feedback process involved in adding/deleting carrier operations, with the same reason for failure.

Further, the base station performs reporting in a period of time, and can directly report the number of success/failures of increasing the carrier, or the number of success/failures of the carrier.

The network management side (such as EMS) counts the received base station resource reconfiguration result in a certain period of time (such as one hour or one day). For example, for base station/cell 1, the number of times of increasing the carrier is nl, and the number of success times is n2. For base station/cell 2, the number of times of deleting carriers is n3, and the number of successes is n4; for base station/cell 3, the number of added hardware resources is n5 (in hardware processing units such as digital signal processors (DSPs) or on-site The Field-Programmable Gate Array (FPGA) is used, and the hardware resource used is n6.

The EMS uploads the resource reconfiguration statistics to the NMS, and the NMS makes performance statistics for resource reconfiguration. For base station/cell 1, the success rate of increasing the carrier is the ratio of n2 to nl (n2/nl); for base station/cell 2, the success rate of deleting the carrier is the ratio of n4 to n3 (n4/n3); for the base station/cell 3, the increased hardware resource utilization is the ratio of n6 to n5 (n6/n5);

Then, based on the performance statistics, the NMS adjusts the resource reconfiguration policy of the network and replaces the added or deleted carriers in order to achieve the goal of reducing the number of resource reconfiguration failures. It is also possible to optimize network processing, such as interference control, and enhance network coverage.

Further, the foregoing operation process may also be implemented by an independent RMS, where the reconfiguration management system refers to a system dedicated to managing resource reconfiguration in a cognitive radio system (including a resource monitoring module, a reconfiguration algorithm module, and a reconfiguration). The decision module is configured to monitor the resource utilization of the base station, run the reconfiguration algorithm, and generate a resource reconfiguration decision, which can be integrated on the network management side or an independently set physical entity, and has an independent interaction interface with the network management side and the access network side. . In the performance measurement of spectrum reforming, the process shown in Figure 3 can be performed: First, the RMS is based on market demand (such as customer growth, increased traffic) and changes in the wireless environment (such as GSM traffic load, LTE service) The load is high), and the spectrum reforming decision is made to reconfigure some or all of the GSM bands in the original system (such as the uplink 900MHz-915Mhz in the 900MHz band and the downlink 945MHz-960MHz) into the LTE system (FDD standard or TDD standard). The RMS delivers a reconfiguration command to the base station, and the reconfiguration command includes at least one of the following: a base station and/or a cell identifier of the resource reconfiguration, a re-assigned area range (LAI, RAI, or TAI list), the reconfigured system Frequency band (GSM900MHz, uplink 900-915MHz, downlink 945-960MHz), reconfigurable target system (LTE FDD), re-matching time period (such as 2:00-4:00 in the morning).

Next, the RMS loads performance measurement configuration information about spectrum reforming to the base station, where the performance measurement configuration information is used to perform measurement and counting statistics of the renormalization result and the resource reconfiguration state in the spectrum resource reforming process to measure the spectrum weight. Resource utilization and success rate in the whole process. The specific performance measurement count includes at least one of the following: the number of successful spectrum reforming, the number of failures of spectrum reforming, and the number of resources for spectrum reforming (number of PRBs).

The base station performs statistical measurement in the spectrum re-forming process according to the measurement statistics in the performance measurement configuration information, and feeds back the spectrum re-forming result and the re-forming progress to the RMS. For the spectrum re-forming result, if the re-matching frequency bands are not all re-formed into the target system during the reconfiguration period (such as the GSM band uplink 900-915MHZ, the downlink 945-960MHz, not all changes in the early morning hours) In the case of the LTE system, the spectrum reconfiguration fails, otherwise the spectrum reconfiguration succeeds; or if some frequency bands are reconfigured in the reconfiguration time period, the number of resources that complete the spectrum reforming needs to be fed back (for example, 50 PRBs are completed.) ), also considered that spectrum reforming was successful.

Further, during the reconfiguration period, the base station may periodically report or trigger the number of resources for reporting the spectrum reforming due to the RMS command.

Further, other frequency bands of the GSM system are reconfigured into an LTE/UMTS system, or the frequency bands of the UMTS system are reconfigured into an LTE system, and the operation process is as described above. The RMS counts the reconfiguration results of the spectrum reforming over a certain period of time (eg, an hour or a day). For example, if the number of times of spectrum re-establishment for base station/cell 1 is nl, the number of successful times of spectrum reforming is n2; the number of times of spectrum re-establishment of base station/cell 2 (reconstruction of GSM900MHZ band to LTE system) is n3, and the success of spectrum reforming is successful. The number of times is n4; the number of resources that the base station/cell 3 performs spectrum reforming is n5 (the bandwidth size is 5Mhz, or the number of PRBs is 50 RPB).

The RMS performs performance statistics based on statistical results of spectrum reforming. For example, the success rate of spectrum reforming for base station/cell 1 is n2/nl; for base station/cell 2, the rate of success of spectrum reforming (GSM900MHz band reforming to LTE system) is n4/n3; for base station/cell 3 The resource rate for spectrum reforming is n5/the total number of spectrum reforming resources.

After that, the RMS performs reconfiguration optimization decision based on the performance statistics of the spectrum reforming. Such as adjusting the frequency band of spectrum reforming, and / or bandwidth.

Further, the above-mentioned spectrum reforming operation process can also be completed by the network management side EMS and the NMS.

When performance measurement of service resource reconfiguration between multiple modes is performed, a flow as shown in FIG. 4 may be performed, where the multi-mode refers to FDD and TDD modes, including a UMTS system and an LTE system. This embodiment takes an LTE system as an example.

First, the RMS monitors the utilization of the radio resources on the access network side. The service resource occupancy rate in various modes, such as the resource voice service in the FDD mode, is 50%, the unicast service is 10%, and the broadcast service is 30%. Resource VoIP services in TDD mode take up 20%, and streaming media services take up 30%. The RMS finds that the FDD service resource load is high, and determines the resource reconfiguration. The resources in the TDD mode are used to carry the broadcast service to share the load of the FDD (for example, the TDD mode resource carries 20% of the broadcast service), and then the FDD mode. The resources occupy 70%, and the resources in the TDD mode also occupy 70%, achieving the purpose of balancing the load. The RMS delivers a resource reconfiguration command to the base station, and the resource reconfiguration command includes a broadcast service in the TDD mode, a proportion of services carried (for example, 20% of the bearer broadcast service), and a time period of reconfiguration. Next, the RMS loads performance measurement configuration information about service resource reconfiguration between multiple modes to the base station, and the performance measurement configuration information is used to measure resource utilization and success rate of service resource reconfiguration among multiple modes. The specific performance measurement count includes at least one of the following: the number of times the FDD service is reconfigured as TDD/the number of resources, the number of times the TDD service is reconfigured as FDD/the number of resources, and the number of times the TDD/FDD is reconfigured according to the specific QCI level. (For example, the number of times/the number of resources that QCI2 is reconfigured by FDD to TDD), and the number of reconfigurations of time slots in TDD mode.

The RMS counts the reconfiguration result of the multi-mode service resource reconfiguration of the base station over a period of time (e.g., one hour or one day). For example, the number of times the broadcast service in the FDD mode of the base station 1 is reconfigured as TDD is nl; the number of resources in the TDD mode of the base station 2 is reconfigured as the number of resources of the FDD (eg, 10 PRBs); and the QCI2 in the base station 3 is reconfigured by the FDD. The number of resources for TDD (eg, 20 PRBs); the number of time slots for TDD reconfiguration of base station 4 (eg, 5 time slots under QCI2 are reconfigured as QCI1).

The RMS performs performance statistics of service resource reconfiguration among multiple modes based on the reconfiguration result within a certain period of time. For example, the resource occupancy ratio of the FDD/TDD mode in the QCI2 service; QCI n (n is 0-9) occurs in the resource ratio of multi-mode resource reconfiguration (the ratio of QCI3 service re-allocated to FDD by FDD).

After that, the RMS optimizes the reconfiguration decision based on the performance statistics of the reconfiguration of the service resources among the multiple modes. For example, the reconfiguration time slot in TDD mode, the ratio adjustment of service reconfiguration between FDD and TDD.

Further, the operation process of the service resource reconfiguration between the multiple modes may also be performed by the network management side EMS and the NMS.

It can be seen from the above description that the performance measurement technology of the present invention can make the network heavy in resources by defining measurement objects and measurement types related to resource reconfiguration on the network side, whether it is a method or an apparatus for implementing EMS, NMS, RMS, or the like. During the matching process, the resource utilization of the base station is monitored and managed, and the reconfiguration decision is made in real time, thereby improving resource utilization and spectrum efficiency, saving resources and time.

The above is only the preferred embodiment of the present invention and is not intended to limit the scope of the present invention. Industrial applicability
