Description

Resource allocation method and device
Technical Field
The embodiment of the invention relates to the technical field of communication, in particular to a resource allocation method and device.
Background
With the widespread use of shared-bicycle traffic in the market, Packet Switching (PS) based traffic congestion is also frequently occurring. Currently, a Global System for Mobile Communication (GSM) network has advantages of wide coverage and low cost relative to Code Division Multiple Access (CDMA) and Long Term Evolution (LTE) networks, and therefore, the GSM network is not a choice for the shared single-vehicle service that has low requirements for network traffic, focuses on wide-range coverage, and reduces cost as much as possible.
For GSM networks, a communication link between a terminal and a core network needs to be established in advance before performing PS services. Taking the above-mentioned shared bicycle service as an example, the terminal may specifically include a shared bicycle provided with a bicycle module, that is, only after a communication link is established between the bicycle module and the core network, the server can realize unlocking and locking through data interaction with the bicycle module. Taking unlocking the shared bicycle as an example, after a communication link is established between the bicycle module and the core network, the user may scan a code to unlock the shared bicycle through a device such as a mobile phone, for example, the user scans a two-dimensional code on the shared bicycle through the mobile phone to directly unlock the shared bicycle, or the user obtains an unlocking password from a server through the core network and then manually inputs the password to unlock the shared bicycle.
However, resources used by the PS service are limited, and sufficient PS service resources cannot be allocated to the mobile phone in the cell during unlocking and locking the shared bicycle possibly due to PS service congestion at the PS service peak time, so that the shared bicycle service cannot access the network, which eventually causes the unlocking and locking failure, and reduces the access success rate of the shared bicycle service.
Disclosure of Invention
The embodiment of the invention provides a resource allocation method and a resource allocation device, which can solve the problem that PS service resources are insufficient when PS service is congested.
In order to achieve the purpose, the embodiment of the invention adopts the following technical scheme:
in a first aspect, an embodiment of the present invention provides a method for resource allocation. The method specifically comprises the following steps: and if the amount of the idle resources in the cell is less than the preset threshold, determining the amount of the resources occupied by the first service in the cell, and releasing part or all of the resources occupied by the first service according to the size relationship between the amount of the resources occupied by the first service and the specified threshold. The first service comprises a completed PS service without releasing resources; the specified threshold is the difference value between the preset threshold and the idle resource amount. Therefore, the embodiment of the invention solves the problem that the PS service resources are insufficient when the PS service is congested by reserving the idle resources. For the situation that the amount of idle resources in the cell is insufficient, in the embodiment of the present invention, PS services that have been completed but have not released resources are preferentially released, so as to achieve full utilization of resources. In addition, in consideration of the overall PS service execution efficiency, in the process of releasing the resource occupied by the first service, it is not necessary to release all the resources occupied by the first service, and if a part of the resources occupied by the first service is released, the amount of the idle resources in the cell can meet the limit requirement of the preset threshold, and then only the part of the resources can be selected to be released, thereby ensuring that the resources can be allocated to the newly accessed PS service when the PS service is congested.
In a possible design, according to a size relationship between the amount of resources occupied by the first service and a specified threshold, releasing part or all of the resources occupied by the first service may be implemented as: if the resource amount occupied by the first service is larger than the designated threshold, releasing the resources corresponding to the designated threshold in all the resources occupied by the first service; and if the resource amount occupied by the first service is less than or equal to the specified threshold, releasing all resources occupied by the first service. In order to ensure the full utilization of resources, in the embodiment of the present invention, as long as the amount of idle resources in the cell meets the limit requirement of the preset threshold, it is not necessary to release more resources occupied by the first service. Therefore, for the first service without the released resource, if the service associated with the first service is attempted to be executed or the first service is repeatedly executed, no new resource needs to be applied to the base station controller, so as to provide convenience for the execution of other PS services as far as possible under the condition of ensuring sufficient free resources.
In one possible design, if all resources occupied by the first service are released and the amount of idle resources in the current cell is still less than the preset threshold, the resources occupied by the second service are released. Therefore, for the situation that all resources occupied by the first service are released and the amount of idle resources in the current cell still does not meet the limit of the preset threshold, in the embodiment of the present invention, the resources occupied by the second service may also be continuously released to ensure that sufficient idle resources exist in the cell, so as to ensure that sufficient PS service resources still remain when the PS service is congested.
In a possible design, the releasing of the resource occupied by the second service may be specifically implemented as: determining a difference value between a preset threshold and the amount of idle resources in the current cell; and releasing the resource quantity occupied by the second service until the released resource quantity occupied by the second service is greater than or equal to the difference between the preset threshold and the idle resource quantity in the current cell. It can be seen that the release of the resources occupied by the second service is performed only when the resources occupied by the first service are not enough to complement the idle resources required by the preset threshold. For resources occupied by the first service, the resources occupied by the second service are generally resources used by the executing PS service, and the release of such resources is often hidden from the normal execution of the second service, for example, conditions such as service interruption and abnormal termination may occur. However, in view of the purpose of the embodiments of the present invention to provide sufficient idle resources for a specific PS service, in order to ensure that sufficient idle resources exist in a cell for a non-specific PS service with a low priority and a low requirement on latency, in the embodiments of the present invention, after all resources occupied by a first service are released, resources occupied by a second service are preferentially released.
In a possible design, if the amount of idle resources in the cell is less than a preset threshold, determining the amount of resources occupied by the first service in the cell may specifically be implemented as: and if the PS service of the newly accessed cell exists and the idle resource amount in the cell is less than a preset threshold, determining the resource amount occupied by the first service in the cell. The resource configuration process may be a real-time, periodically or aperiodically triggered process. However, from the perspective of saving resources, if the number of PS services in a cell is only decreased and not increased, i.e. there is no PS service of a newly accessed cell, then the amount of idle resources in the cell is usually only increased and not decreased at this time. Therefore, in the embodiment of the present invention, if there is a PS service of a newly accessed cell, the base station controller determines whether the amount of idle resources in the cell is less than a preset threshold, and triggers the whole resource allocation process when the amount of idle resources is less than the preset threshold. Therefore, on the basis of ensuring that the amount of the idle resources meets the limit of the preset threshold, resources consumed by resource allocation are saved as much as possible.
In one possible design, the second traffic includes PS traffic that is lower priority than the third traffic. And the third service is a PS service except the first service and the second service in the cell. Therefore, the service of the released resource is necessarily the service with relatively low priority, that is, on the premise of ensuring the smooth execution of the high-priority service, the idle resource is reserved for the use of the newly accessed service.
In a possible design, the third service at least includes a PS service initiated by a terminal corresponding to the specified international mobile subscriber identity IMSI, and the terminal or the specified server sends the PS service carrying the IP address of the specified server in the PS service execution process. That is, the third service includes a specific PS service, taking the specific PS service as a shared bicycle service as an example, the terminal accessing the shared bicycle service is often a terminal installed with a shared bicycle application program, and the IMSI of the terminal is fixed, so as long as it is determined that the main body executing the PS service is the terminal, even if the priority of the PS service currently executed by the terminal is lower than that of other PS services in the cell, the PS service currently executed by the terminal is not considered in the process of releasing the resource. Similarly, in addition to determining whether the terminal is a terminal performing a specific PS service through the IMSI of the terminal, it may also be determined through the server IP address. Also taking a specific PS service as an example of a shared single-vehicle service, a certain server or a certain group of specific servers often serve the shared single-vehicle service belonging to the same enterprise name, and once the type of the PS service is determined, the server or the group of specific servers corresponding to the PS service can be determined, and the IP address of the specific server can be determined, so that the PS service can be distinguished through the IP address of the server. Similar to the foregoing situation, in the process of releasing the resource, the PS service corresponding to the IP address of the specific server is not released in the execution process, and if the PS service being executed does not actively release the resource, the PS service is not forced to release the occupied resource after the execution of the PS service is finished. For the kind of the third service, the above cases are only an example, and are not a limitation of the third service.
In one possible design, the second service does not include PS services that attempt to access the cell but do not yet successfully access the cell, and PS services that specify the terminal where the subscriber identity module SIM card is located. In the execution process of the PS service, the access of the cell needs to be completed first, and then the PS service is executed through data interaction. In the embodiment of the invention, for the PS service which is not accessed into the cell, the resources of the PS service are not released when the PS service is successfully accessed into the cell, even if the priority of the PS service is lower, the base station controller selectively releases the resources occupied by the PS service only after the PS service is successfully accessed into the cell. If the PS service has been released before the PS service has not successfully accessed the cell, the PS service can only access the cell after waiting for the base station controller to allocate resources for the PS service, and there may be a risk of releasing the resources after accessing the cell, so that the PS service may not be successfully executed for a long time. Therefore, in order to avoid the above situation, in the embodiment of the present invention, for a PS service that attempts to access a cell but does not successfully access the cell, it is first ensured that the PS service accesses the network, and then it is considered whether resources occupied by the PS service need to be released. In addition, for the end user, many SIM cards already determine the special identity of the SIM card when the SIM card is opened, for example, the user needs to pay a high fee to replace the SIM card with the special identity, i.e. to designate the SIM card, thereby ensuring that the SIM card has a higher priority than other users during the use process. That is, the service initiated by the terminal where the specified SIM card is located will obtain a higher network speed, etc. Therefore, in the embodiment of the present invention, in order to continuously guarantee the rights and interests of such users, while reserving the free resources, the usage rights and interests of such users are preferentially reserved, that is, the PS services triggered by such users are not considered in the process of releasing the resources.
In a second aspect, an embodiment of the present invention provides an apparatus for resource allocation. The apparatus may implement the functions implemented in the above method embodiments, and the functions may be implemented by hardware or by hardware executing corresponding software. The hardware or software comprises one or more modules corresponding to the functions.
In one possible design, the apparatus includes a processor and a transceiver in the structure, and the processor is configured to support the apparatus to perform the corresponding functions of the method.

The apparatus may also include a memory, coupled to the processor, that retains program instructions and data necessary for the apparatus.

Detailed Description
The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention. For the Chinese and English comparison of the technical terms referred to herein, see Table I.

The embodiment of the invention can be used for a communication network system which at least comprises a base station controller, a base station and a terminal. The terminal and the base station may perform data interaction, the base station and the base station controller may perform data interaction, and one base station controller may be configured to control multiple base stations, for example, the base station controller may implement functions of channel allocation and controlling service switching from one base station to another base station. It should be noted that the terminal may specifically be a shared bicycle, a POS device, an intelligent electric meter, an intelligent water meter, a mobile phone, and the like, which is provided with a bicycle module, in the embodiment of the present invention, the type of the terminal is not limited, as long as it is ensured that the terminal can initiate an access request of the PS service, or the terminal can be used as a main body for executing the PS service.
As shown in fig. 1, the communication network system may further include a server, and the server performs data interaction with the base station controller through the core network. Taking unlocking of the shared bicycle as an example, if a user uses the UE to initiate a request for trying to use the shared bicycle to the base station by scanning the two-dimensional code on the shared bicycle, the base station may report the request to the base station controller after receiving the request, and the base station controller determines the server corresponding to the IP address according to the IP address of the server carried in the request, and then sends the request to the server. And then, the server can initiate a process of establishing a communication link with the sharing bicycle, and after the communication link is successfully established between the server and the sharing bicycle, the sharing bicycle can unlock the sharing bicycle and trigger operations such as charging, timing and the like according to an instruction sent by the server so that the user can use the sharing bicycle.
An embodiment of the present invention provides a resource allocation method based on PS service, as shown in fig. 2, where the method may be executed by a base station controller shown in fig. 1, and the method specifically includes:
step 101, determining the resource amount occupied by the first service in the cell if the idle resource amount in the cell is less than a preset threshold.
Wherein the first service comprises a PS service which is completed and resources are not released.
In general, the first service may also include PS service regarded as being in an extended inactive period, that is, PS service that is already executed in view of the service execution state. However, the service of this type still continues to occupy part of the resources after being executed, and although the part of the resources is still in the occupied state, the part of the resources is idle in consideration of the actual use situation, so in the embodiment of the present invention, the part of the resources is preferentially released for other PS services to use. In addition, the first service may also include PS service that is periodically executed for a short time, for example, some M2M services may be executed once every certain time interval, and for this kind of service, even if the current execution process is interrupted, the execution will be executed after the certain time interval, so the above-mentioned interruption does not have a great influence on the execution of the PS service. Of course, some of the M2M services described above may also be regarded as the second service described herein, and the description of the second service will be presented later and will not be described in detail herein.
The base station controller may allocate resources for performing the PS service to each cell in advance, and since the resources for performing the PS service in each cell are limited, in order to ensure that when the PS service such as the shared bicycle service is accessed, sufficient resources are still available in the cell to perform the PS service, a part of the resources need to be reserved in the cell for the PS service.
For the embodiment of the invention, the staff can preset the preset threshold according to the experience value, and release the resources occupied by part of the service when the idle resources in the cell do not meet the resource amount limited by the preset threshold, so as to ensure that enough idle resources are occupied by the new PS service when the new PS service is accessed in the cell. The idle resource amount is used to indicate the amount of resources in an idle state in a cell, and the idle resources refer to those resources that can be invoked by the PS service or resources that are currently in an idle state.
It should be noted that the preset threshold may be a fixed parameter or a variable parameter. When the preset threshold is a variable parameter, the preset threshold may be considered to change with time, and the change may be periodic or aperiodic, and the actual change of the preset threshold and the change amplitude when the change occurs are not particularly limited in the embodiment of the present invention. For example, in a peak period of the PS service, for example, in a peak period of the early and late days, the PS service such as the shared bicycle service may be in a trigger peak period, and therefore, at this time, the resources required by the PS service are more, the preset threshold may be set to a larger parameter, so as to ensure that there are enough idle resources in the cell for the PS service to occupy. Therefore, the preset threshold of each time period can be set to be the same or different parameters, and similarly, different cells can also be set to be the same or different parameters due to different PS service requirements, which means that the preset threshold can also be set according to regions. It should be noted that the setting manner of the preset threshold is only one possible example, and is not a limitation when the preset threshold is configured.
In addition, in the embodiment of the present invention, the preset threshold may also be a fixed parameter range or a variable parameter range, and when the idle resources in the cell are in the parameter range, it is considered that the idle resources in the cell are sufficient or insufficient, and when the idle resources are insufficient, the resources occupied by the first service in the cell are determined, and then the subsequent steps are executed. It can be seen that, in the embodiment of the present invention, the type of the preset threshold is not limited too much. In order to facilitate the base station controller to complete the parameter judgment of the idle resources, a fixed parameter or a variable parameter is usually set, so that the base station controller can determine whether the amount of the idle resources in the current cell meets the limit of a preset threshold only by comparing the magnitude relation between the idle resources and the fixed parameter or the variable parameter. If the preset threshold is a parameter range, in the process of comparing the relation between the idle resources and the preset threshold, it is likely that two comparison processes are required to finally determine whether the amount of the idle resources in the current cell meets the limit of the preset threshold. The two comparison processes specifically include comparing the amount of idle resources with an upper limit and a lower limit of a parameter range corresponding to a preset threshold, respectively.
For the base station controller, the resources occupied by the PS service accessed to each cell are reported to the base station controller through the base station corresponding to the cell, so that the base station controller can master the use condition of the resources in each cell, thereby determining whether the amount of the idle resources in each cell meets the limit of the preset threshold.
Similarly, because the base station controller can master the execution condition of each PS service, the base station controller can also distinguish the types of the PS services, that is, which PS services belong to the first service, which PS services belong to the second service, and which PS services belong to the third service. It should be noted that the PS service types represented by the second service and the third service are proposed in the following text, and are not described herein again.
After the base station controller determines which PS services belong to the first service, the base station controller may determine the amount of resources currently occupied by all the first services in the same cell, that is, the amount of resources occupied by the first service in the cell in step 101.
It should be noted that, since the first service belongs to the PS service that has been executed but has not released the resource, the base station controller may consider that the resource is in an occupied state but not in a used state, and therefore, in order to reduce the influence on the executing PS service as much as possible, the base station controller may preferentially release the resource occupied by the first service.
In the embodiment of the present invention, the parameter for measuring the resource amount may be the number of TBFs, the resource utilization rate, and the like, and the expression form, the type, and the like of the resource amount are not limited herein.
102, releasing part or all of the resources occupied by the first service according to the size relationship between the resource amount occupied by the first service and the specified threshold.
The designated threshold is the difference value between the preset threshold and the idle resource amount.
In the embodiment of the present invention, when the amount of idle resources is insufficient, the base station controller may ensure that there are enough idle resources in the cell after completing the resource release by releasing the resources currently occupied by the PS service. However, considering that the release of the resource may possibly affect some ongoing PS services, in the embodiment of the present invention, the resource release is completed with reference to a difference between the preset threshold and the amount of the idle resource. That is, on the premise of affecting the normal execution of the PS service as little as possible, the amount of idle resources is restored to the range limited by the preset threshold. It should be noted that a specific implementation manner of releasing a part or all of the resources occupied by the first service is provided later and will not be described herein again.
In addition, in the embodiment of the present invention, the size of the specified threshold may not be calculated, but the current idle resource amount is periodically or in real time compared with the release process of the resource to determine whether the current idle resource amount meets the limit of the preset threshold, however, by using the implementation manner that the specified threshold is not calculated, more resources of the base station controller are often consumed due to frequent comparison processes. Therefore, in order to ensure effective utilization of resources and avoid unnecessary resource waste, in the embodiment of the present invention, a manner of calculating the specified threshold is usually selected to finally determine to release part or all of the resources occupied by the first service.
Therefore, the embodiment of the invention solves the problem that the PS service resources are insufficient when the PS service is congested by reserving the idle resources. For the situation that the amount of idle resources in the cell is insufficient, in the embodiment of the present invention, PS services that have been completed but have not released resources are preferentially released, so as to achieve full utilization of resources. In addition, in consideration of the overall PS service execution efficiency, in the process of releasing the resource occupied by the first service, it is not necessary to release all the resources occupied by the first service, and if a part of the resources occupied by the first service is released, the amount of the idle resources in the cell can meet the limit requirement of the preset threshold, and then only the part of the resources can be selected to be released, thereby ensuring that the resources can be allocated to the newly accessed PS service when the PS service is congested.
In order to ensure the full utilization of resources, after the idle resource quantity meets the limit of a preset threshold, the additionally occupied resource quantity is not released. Therefore, on the basis of the implementation shown in fig. 2, the implementation shown in fig. 3 can also be realized. Step 102 releases part or all of the resources occupied by the first service according to the size relationship between the resource amount occupied by the first service and the specified threshold, which may be specifically implemented as step 201 and step 202:
step 201, if the amount of resources occupied by the first service is greater than the specified threshold, releasing resources corresponding to the specified threshold from all resources occupied by the first service.
Step 202, if the amount of resources occupied by the first service is less than or equal to the specified threshold, releasing all resources occupied by the first service.
Before releasing the resource, the base station controller may determine the size of the resource amount to be released in a calculation manner, and then release the resource occupied by the first service according to the obtained pre-released resource amount. It should be noted that, if the resource amount occupied by the first service can satisfy the calculated pre-released resource amount, only a part of the resources occupied by the first service is released in the releasing process. That is, as long as it is ensured that the amount of idle resources can meet the limit of the preset threshold after the release is completed, for the first service whose resources are not released, if the PS service associated with the service needs to be executed continuously or the first service needs to be executed continuously, the PS service to be executed can directly use the resources occupied by the first service without applying for resources from the base station controller again, thereby saving the process of requesting resources in the service processing process and improving the execution efficiency of the service.
It should be noted that, for the case that the amount of idle resources in the cell is small, the base station controller needs to release most or all of the resources occupied by the first service, and then, in order to save the total consumption of the resource releasing process, the size of the amount of resources that needs to be released may be calculated while releasing the resources. Thus, when the calculation process is completed, the amount of the released resources does not reach the amount of the pre-released resources. This means that the calculation process of the base station controller is performed simultaneously with the release process, which further saves the time spent on reserving free resources.
In order to ensure that sufficient PS service resources are still reserved when the PS service is congested, for the case that all resources occupied by the first service are released, the resources occupied by the second service may also be continuously released until the current amount of idle resources meets the limit of the preset threshold. Therefore, on the basis of the implementation shown in fig. 3, the implementation shown in fig. 4 can also be realized. After step 202 is executed, if the amount of resources occupied by the first service is less than or equal to the specified threshold, all resources occupied by the first service are released, step 103 may also be executed:
and 103, if the amount of the idle resources in the current cell is still less than the preset threshold, releasing the resources occupied by the second service.
Considering that the number of the first services is limited, after all resources occupied by the first services are released, there is still a high possibility that the amount of idle resources does not meet the limit of the preset threshold. Therefore, in order to ensure that the amount of idle resources meets the limit of the preset threshold, in the embodiment of the present invention, resources of other PS services also need to be released. It should be noted that, the release process of the resources occupied by other services will be proposed later, and will not be described herein.
It should be noted that, in the embodiment of the present invention, the second service may include a PS service with a lower priority than a third service, where the third service is a PS service in a cell except for the first service and the second service. The third service may at least include a PS service initiated by the terminal corresponding to the specified IMSI, and the terminal or the specified server sends the PS service carrying the IP address of the specified server in the PS service execution process.
That is, the third service includes a specific PS service, taking the specific PS service as a shared bicycle service as an example, the terminal accessing the shared bicycle service is often a terminal installed with a shared bicycle application program, and the IMSI of the terminal is fixed, so as long as it is determined that the main body executing the PS service is the terminal, even if the priority of the PS service currently executed by the terminal is lower than that of other PS services in the cell, the PS service currently executed by the terminal is not considered in the process of releasing the resource. Similarly, in addition to determining whether the terminal is a terminal performing a specific PS service through the IMSI of the terminal, it may also be determined through the server IP address. Also taking a specific PS service as an example of a shared single-vehicle service, a certain server or a certain group of specific servers often serve the shared single-vehicle service belonging to the same enterprise name, and once the type of the PS service is determined, the server or the group of specific servers corresponding to the PS service can be determined, and the IP address of the specific server can be determined, so that the PS service can be distinguished through the IP address of the server. Similar to the foregoing situation, in the process of releasing the resource, the PS service corresponding to the IP address of the specific server is not released in the execution process, and if the PS service being executed does not actively release the resource, the PS service is not forced to release the occupied resource after the execution of the PS service is finished. For the kind of the third service, the above cases are only an example, and are not a limitation of the third service.
Furthermore, the second service may not include PS services that attempt to access the cell but do not yet successfully access the cell, and PS services that are initiated by a terminal in which the specified SIM card is located, such as terminal-initiated PS services used by a user such as QoS ARP 1. It should be noted that the release is not performed for those users in the GMM signaling flow, that is, for those users in the packet domain mobility management process.
In the execution process of the PS service, the access of the cell needs to be completed first, and then the PS service is executed through data interaction. In the embodiment of the invention, for the PS service which is not accessed into the cell, the resources of the PS service are not released when the PS service is successfully accessed into the cell, even if the priority of the PS service is lower, the base station controller selectively releases the resources occupied by the PS service only after the PS service is successfully accessed into the cell. If the PS service has been released before the PS service has not successfully accessed the cell, the PS service can only access the cell after waiting for the base station controller to allocate resources for the PS service, and there may be a risk of releasing the resources after accessing the cell, so that the PS service may not be successfully executed for a long time. Therefore, in order to avoid the above situation, in the embodiment of the present invention, for a PS service that attempts to access a cell but does not successfully access the cell, it is first ensured that the PS service accesses the network, and then it is considered whether resources occupied by the PS service need to be released. In addition, for the end user, many SIM cards already determine the special identity of the SIM card when the SIM card is opened, for example, the user needs to pay a high fee to replace the SIM card with the special identity, i.e. to designate the SIM card, thereby ensuring that the SIM card has a higher priority than other users during the use process. That is, the service initiated by the terminal where the specified SIM card is located will obtain a higher network speed, etc. Therefore, in the embodiment of the present invention, in order to continuously guarantee the rights and interests of such users, while reserving the free resources, the usage rights and interests of such users are preferentially reserved, that is, the PS services triggered by such users are not considered in the process of releasing the resources.
It should be noted that, the staff may also increase or decrease the type of the PS service related to the second service according to the requirement of the current cell, and the service situation not included in the second service is only an example, and is not limited to the content of the second service.
Therefore, for the situation that all resources occupied by the first service are released and the amount of idle resources in the current cell still does not meet the limit of the preset threshold, in the embodiment of the present invention, the resources occupied by the second service may also be continuously released to ensure that sufficient idle resources exist in the cell, so as to ensure that sufficient PS service resources still remain when the PS service is congested.
In the embodiment of the present invention, an implementation manner is provided for specifically releasing resources occupied by a second service after releasing all resources occupied by a first service, if an amount of idle resources does not meet a limit of a preset threshold yet. On the basis of the implementation shown in fig. 4, the implementation shown in fig. 5 can also be realized. If the amount of idle resources in the current cell is still smaller than the preset threshold in step 103, releasing resources occupied by the second service, which may be specifically implemented as step 301 and step 302:
step 301, if the amount of idle resources in the current cell is still less than the preset threshold, determining a difference between the preset threshold and the amount of idle resources in the current cell.
Step 302, releasing the resource occupied by the second service until the amount of the released resource occupied by the second service is greater than or equal to the difference between the preset threshold and the amount of the idle resource in the current cell.
Similar to the content considered in the process of releasing the resources occupied by the first service, the effective utilization of the resources also needs to be considered, and therefore, in the releasing process, the difference between the preset threshold and the amount of the idle resources in the cell after all the resources occupied by the first service are released needs to be considered. That is, in the process of releasing the resource occupied by the second service, it is only necessary to ensure that the amount of the idle resource in the cell after the release meets the limit of the preset threshold.
In addition, referring to the contents highlighted in step 201 and step 202, the base station controller may also release part or all of the resources occupied by the second service after the calculation, or calculate the amount of resources to be released in the release process, which is not described herein again.
It can be seen that the release of the resources occupied by the second service is performed only when the resources occupied by the first service are not enough to complement the idle resources required by the preset threshold. For resources occupied by the first service, the resources occupied by the second service are generally resources used by the executing PS service, and the release of such resources is often hidden from the normal execution of the second service, for example, conditions such as service interruption and abnormal termination may occur. However, in view of the purpose of the embodiments of the present invention to provide sufficient idle resources for a specific PS service, in order to ensure that sufficient idle resources exist in a cell for a non-specific PS service with a low priority and a low requirement on latency, in the embodiments of the present invention, after all resources occupied by a first service are released, resources occupied by a second service are preferentially released.
Considering that when a newly accessed PS service exists in a cell, the amount of idle resources in the cell may be more possibly affected, and therefore, in order to save resources such as calculation, processing and the like consumed in the process of reserving the idle resources, in the embodiment of the present invention, the whole process of resource configuration may be triggered only after the new PS service accesses the cell. Therefore, on the basis of the implementation shown in any one of fig. 2 to fig. 5, taking fig. 2 as an example, the implementation shown in fig. 6 can also be implemented. In step 101, if the amount of idle resources in the cell is less than the preset threshold, determining resources occupied by the first service in the cell, which may be specifically implemented as step 401:
step 401, if there is a PS service of a new access cell and the amount of idle resources in the cell is less than a preset threshold, determining the amount of resources occupied by a first service in the cell.
In the embodiment of the present invention, the resource allocation process may be a real-time, periodic or aperiodic triggering process. However, from the perspective of saving resources, if the number of PS services in a cell is only decreased and not increased, i.e. there is no PS service of a newly accessed cell, then the amount of idle resources in the cell is usually only increased and not decreased at this time. Therefore, in the embodiment of the present invention, if there is a PS service of a newly accessed cell, the base station controller determines whether the amount of idle resources in the cell is less than a preset threshold, and triggers the whole resource allocation process when the amount of idle resources is less than the preset threshold. Therefore, on the basis of ensuring that the amount of the idle resources meets the limit of the preset threshold, resources consumed by resource allocation are saved as much as possible.
As shown in fig. 7, a flow is implemented for one possible resource allocation. Wherein, the parameter used for expressing the resource quantity is the TBF quantity. The implementation process specifically includes:
step 501, the new PS service is accessed into the cell.
Step 502, the base station controller allocates channel resources for the new PS service.
Step 503, the base station controller calculates the cell load.
In the embodiments of the present invention, not the amount of free resources but the amount of occupied resources is considered. Therefore, the implementation manner for determining whether to release the resources occupied by the first service and the second service according to the amount of the idle resources can be implemented as determining whether to release the resources occupied by the first service and the second service according to the current cell load condition.
It should be noted that, whether the cell load or the amount of idle resources is considered, the trigger condition is only a possible trigger condition of the resource allocation procedure, and is not a necessary trigger condition of the resource allocation procedure.
Step 504, the base station controller determines whether the cell load is less than a threshold. If the cell load is less than the threshold value, ending the resource allocation process; otherwise, step 505 is performed.
Step 505, the base station controller calculates the number RelNum of TBFs to be released.
Step 506, the base station controller traverses all TBFs in the cell, and searches for ExistNum of the low-priority TBFs which can be released through flow trigger.
It should be noted that the low priority traffic may be regarded as the first traffic.
Step 507, the base station controller judges whether RelNum is less than or equal to ExistNum. If RelNum is less than or equal to ExistNum, go to step 508; otherwise, step 509 and step 510 are performed.
Step 508, the base station controller releases the low priority TBF of RelNum through flow trigger.
Step 509, the base station controller traverses all TBFs in the cell, and enforcedly releases (RelNum-ExistNum) TBFs with the next lower priority according to a certain priority.
It should be noted that the second lowest priority traffic may be regarded as the second traffic.
Step 510, the base station controller releases the low priority TBF of ExistNum through flow trigger.
Since there is no restriction on the order of step 509 and step 510 in the implementation process, step 509 and step 510 may be executed in a certain order, or simultaneously. The implementation process of executing the two steps in the order of executing step 509 and then executing step 510 is only shown in fig. 7, but not limited to the implementation timing of the two steps.
