s2: and after the network element receives the switching signaling in the switching stage, controlling the resource configuration process of the network element to be executed in parallel.
The method for controlling handover of a base station provided in embodiment 1 can be applied to any controller or other devices to which the method is applied, and is hereinafter referred to as "controller" in embodiment 1, which is a party for controlling handover; also, the method for controlling base station handover provided in embodiment 1 can be used to process any base station or other devices applicable to the method, and is hereinafter referred to as "base station" in embodiment 1, and is the same as "base station" mentioned in step S1, and is the party to be controlled for handover; the network element is a module or unit for processing information transmission inside the base station.
The controller executes step S1: the method comprises the steps of identifying a switching stage of current base station switching, wherein the switching stage of the base station is divided into a switching preparation stage, a switching execution stage and a switching completion stage; the resource allocation process of the network element is different in each switching stage, so the controller firstly recognizes the switching stage of the current base station; the controller executes step S2: after receiving the switching signaling in the switching stage, the network element controls the resource configuration process of the network element to be executed in parallel; the parallel execution of the resource allocation process can shorten the time length of the whole process, thereby improving the efficiency of base station switching and improving the experience of users when switching base stations.
As a preferred solution, in the operation of "controlling the parallel execution of the resource allocation process of the network element" in step S2, the specific execution process of the controller is: and controlling the network elements to be parallelly built and sending resource allocation request information.
The controller controls the resource allocation process to be executed in parallel in the network element, and the specific control mode is to control the network element to parallelly construct resource allocation request information, and after the construction is finished, control the network element to internally send the resource allocation request information to a corresponding resource allocation module in the network element, so that the parallel resource allocation in the network element is realized; after the resource allocation request information is sent to the corresponding resource allocation module, the resource allocation module responds to the corresponding resource allocation response information in the network element, and the network element completes the resource allocation process after receiving all the resource allocation response information.
As a preferred solution, as shown in fig. 2, after step S2 is completed, the controller performs the following operation steps:
s3: starting a timer, if at least one response time of the resource allocation response information exceeds the time of the timer, executing step S4; if the response time of all the resource allocation response messages does not exceed the time of the timer, executing step S5;
S4: judging that the overtime abnormal condition occurs in the resource allocation process, and executing response overtime processing;
s5: when the network element receives all the resource allocation response information, closing the timer;
after executing step S2, the controller monitors whether the whole parallel resource configuration process is normal or not through setting of a timer, and the controller executes step S3: starting a timer, wherein the time set by the timer is the time for which all the resource allocation response information is pre-calculated to respond under normal conditions; if at least one of the resource allocation response messages is not returned to the network element within the time specified by the timer, the controller executes step S4: judging that the resource allocation process has overtime abnormal conditions and executing response overtime processing, thereby solving the problems of overtime response or failure response of the request encountered by the current resource allocation; if all the resource allocation response information returns to the network element within the time specified by the timer, the controller executes step S5, and when the network element receives all the resource allocation response information, the timer is closed, and the controller successfully controls the network element to complete the parallel execution of the resource allocation process. The controller can monitor the response failure and the response overtime condition of the resource configuration by setting a timer in the parallel resource configuration executing process, and timely process overtime abnormality.
As a preferred solution, as shown in fig. 3, the specific implementation procedure of the controller in step S3 is as follows:
s31: starting a timer;
s32: after the network element receives each piece of resource allocation response information, setting configured flag bits in the resource allocation response information and resource allocation request information corresponding to the resource allocation response information;
in the operation of "execute response timeout process" in step S4, the specific execution procedure of the controller is: according to the configured flag bit in step S32, the controller releases the resource allocation request information and the resource allocation response information with the configured flag bit.
After starting the timer, when the network element receives the resource allocation response information, the controller sets the configured flag bit in the resource allocation response information and the corresponding resource allocation request information, which represents that the resource allocation corresponding to the resource allocation request information is completed. If at least one response time of the resource allocation response information exceeds the time of the timer, indicating that the timeout exception occurs in the resource allocation process, the controller needs to locate all the resources that have been configured according to the configured flag bit in step S32, and execute step S4: and releasing all the resource allocation request information and the resource allocation response information with the allocated flag bit, so as to avoid the residual unused resources in the network element.
As a preferred solution, as shown in fig. 4, the controller further performs the following operation steps in the process of controlling the handover of the base station:
d1: identifying a terminal initiating the base station switching, and distributing a context for the terminal;
d2: and managing the process and the state of the terminal in the base station switching through the context of the terminal.
When a terminal initiates base station switching, a controller identifies the terminal and distributes contexts for the terminal, wherein each context uniquely corresponds to the state of the terminal, so that the process and the state of the terminal in the base station switching can be managed through the context of the terminal, the step D1 is executed before the step S1, and the controller is ensured to identify and manage each terminal, so that the terminals are not interfered with each other in the base station switching process; the step D2 may be performed at any stage of the handover of the base station after the step D1 is completed.
As a preferred solution, the specific implementation procedure of the controller in step D1 is: identifying the terminal through the identifier of the terminal, and distributing a context for the terminal; when any network element that does not uniquely identify the terminal receives any handover instruction about the terminal, as shown in fig. 5, the controller performs step D11:
D11: and when any network element starts the resource allocation process of the terminal, the terminal and the network element are uniquely identified.
The specific implementation process of the controller in the step D2 is as follows: and in each resource allocation process, determining the context of each terminal through the unique identification, and further managing the process and state of the terminal in the base station switching through the context of the terminal.
The step D1 still needs to be performed before the step S1, the controller may perform the step D11 when any network element that does not perform unique identification with the terminal receives any handover command regarding the terminal at any stage of the base station handover after the step S1 is completed, and the controller may perform the step D2 only for the network element and the terminal with the unique identification because the unique identification in the step D11 is involved in the step D2, that is, for the same network element and terminal, the controller needs to perform the step D11 before performing the step D2.
Each terminal is provided with an identifier of the terminal, the controller can identify the terminal more accurately through the identifier of the terminal, after context is allocated to the terminal, when any network element starts the resource allocation process of the terminal, the controller carries out unique identification on the terminal and the network element, namely, the state of the terminal switched at the current base station is identified through the resource allocation process of the network element, and the context of the terminal is processed. Therefore, after the unique identifier, when the network element receives any switching instruction, the controller can determine the context of the terminal through the unique identifier which is set in the network element, and perform base station switching processing on the context of the terminal while configuring resources, so that the base station switching of the terminal is better managed.

As shown in fig. 6, in the handover preparation phase, the network element CU of the target base station receives a handover request at the l3 layer, and then the controller performs step S1: identifying the switching stage of the current base station switching as a switching preparation stage; the controller executes step S2: controlling the interior of the target base station network element CU to execute a resource allocation process in parallel; in the handover preparation stage, the target base station network element CU configures resources of a data link layer of a terminal initiating the handover of the base station, including internally configuring resources of f1, pdcp, ngu and f1u, and the controller controls the target base station network element CU to concurrently configure f1 resource configuration request information, pdcp resource configuration request information, ngu resource configuration request information and f1u resource configuration request information, and after the configuration is completed, the distributor in the target base station network element CU sends the resource configuration request information (arrows 3, 4, 5 and 7 in the figure represent four resource configuration request information) to a corresponding resource configuration module, and waits for resource configuration response information (6, 8, 9 and 10 in the figure represent four resource configuration response information) of each resource configuration request information to respond; the resource allocation request information represented by arrow 7 is f1u, and this resource allocation request information must be sent after the response of the resource allocation response information of the f1 resource allocation request information, so that it cannot be sent in parallel with the resource allocation request information represented by arrows 3, 4, and 5 in the figure.
As shown in fig. 7, in the handover preparation stage, the network element DU of the target base station receives the F1uecontext setup request at the l3 layer, and then the controller performs step S1: identifying the switching stage of the current base station switching as a switching preparation stage; the controller executes step S2: controlling the interior of the target base station network element DU to execute a resource allocation process in parallel; in the handover preparation stage, the resources of the data link layer and the physical layer of the terminal initiating the handover of the base station are configured by the target base station network element DU, including the resources of the internal configuration cmac, l2 and f1u, and the controller controls the target base station network element DU to parallelly configure the cmac resource configuration request information, the l2 resource configuration request information and the f1u resource configuration request information, and after the configuration is completed, the distributor in the target base station network element DU sends the resource configuration request information (arrows 3, 4 and 5 in the figure, representing three resource configuration request information) to the corresponding resource configuration module, and waits for the resource configuration response information (6, 7 and 8 in the figure represent three resource configuration response information) of each resource configuration request information to respond.
As shown in fig. 8, in the handover execution stage, the network element CU of the source base station receives a handover command at the l3 layer, and then the controller performs step S1: identifying the switching stage of the current base station switching as a switching execution stage; the controller executes step S2: controlling the source base station network element CU to execute a resource allocation process in parallel; in the handover execution stage, the source base station network element CU configures the data link layer resources of the terminal initiating the base station handover, including the resources of the internal configuration f1, pdcp and ngu, and the controller controls the source base station network element CU to concurrently configure the f1 resource configuration request information, the pdcp resource configuration request information and the ngu resource configuration request information, and after the configuration is completed, the distributor in the source base station network element CU sends the above resource configuration request information (arrows 3, 4 and 5 represent three resource configuration request information in the figure) to the corresponding resource configuration module, and waits for the resource configuration response information (6, 7 and 8 represent three resource configuration response information in the figure) of each resource configuration request information to respond.
Preferably, after each network element completes step S2, the controller continues to execute the following operation steps:
s3: starting a timer and waiting for resource allocation response information of all the resource allocation request information to respond to the network element; if the response time of at least one resource allocation response message exceeds the time of the timer, executing step S4; if the response time of all the resource allocation response messages does not exceed the time of the timer, executing step S5;
s4: judging that the overtime abnormal condition occurs in the resource allocation process, and executing response overtime processing;

in the operation of "execute response timeout process" in step S4, the specific execution procedure of the controller is: according to the configured flag bit in step S32, the controller releases the resource allocation request information and the resource allocation response information with the configured flag bit.
As shown in fig. 7, taking the resource configuration of the network element DU of the target base station in the handover preparation stage as an example, after the controller starts the timer, the controller sets the configured flag bit in both the resource configuration request information and the corresponding resource configuration response information when the corresponding resource configuration response information is received by the resource configuration request information in the process of waiting for the resource configuration response information of the resource configuration request information, for example, when the cmac resource configuration response information represented by arrow 6 is responded, the controller sets the configured flag bit in the cmac resource configuration request information represented by arrow 3 and the cmac resource configuration response information represented by arrow 6. When the response time of at least one of the resource allocation response messages exceeds the time of the timer, the controller needs to locate all the resources which have been configured according to the configured flag bit in step S32 and execute step S4: and releasing all the resource allocation request information and the resource allocation response information with the allocated flag bit, so as to avoid the residual unused resources in the network element.

d1: identifying a terminal initiating the base station switching, and distributing a context for the terminal;
d2: and managing the process and the state of the terminal in the base station switching through the context of the terminal.
When a terminal initiates base station switching, a controller identifies the terminal and distributes contexts for the terminal, wherein each context uniquely corresponds to the state of the terminal, so that the process and the state of the terminal in the base station switching can be managed through the context of the terminal, the step D1 is executed before the step S1, the controller is ensured to identify and manage each terminal, and the terminals are not interfered with each other in the base station switching process; the step D2 may be performed at any stage of the handover of the base station after the step D1 is completed.
As a preferred solution, the specific implementation procedure of the controller in step D1 is: identifying the terminal through the identifier of the terminal, and distributing a context for the terminal; when any network element which is not uniquely identified with the terminal receives any switching instruction about the terminal, the controller executes step D11:
D11: and when any network element starts the resource allocation process of the terminal, the terminal and the network element are uniquely identified.
The specific implementation process of the controller in the step D2 is as follows: and in each resource allocation process, determining the context of each terminal through the unique identification, and further managing the process and state of the terminal in the base station switching through the context of the terminal.
The step D1 still needs to be performed before the step S1, the controller may perform the step D11 when any network element that does not perform unique identification with the terminal receives any handover command regarding the terminal at any stage of the base station handover after the step S1 is completed, and the controller may perform the step D2 only for the network element and the terminal with the unique identification because the unique identification in the step D11 is involved in the step D2, that is, for the same network element and terminal, the controller needs to perform the step D11 before performing the step D2.

The parallel control module M10 is used for identifying a switching stage of the current base station switching, and controlling the network elements to parallelly construct and send resource configuration request information after receiving a switching instruction in the switching stage; the exception handling module M20 is configured to execute response timeout processing for the resource configuration procedure when the network element does not receive the resource configuration response information of all the resource configuration request information within a preset time.
The specific execution process of the parallel control module M10 when realizing the functions thereof is as follows:
s1: identifying a switching stage of the current base station switching;
s2: after receiving the switching signaling in the switching stage, the network element is controlled to parallelly construct and send resource allocation request information;
the parallel control module M10 performs step S1: the method comprises the steps of identifying a switching stage of current base station switching, wherein the switching stage of the base station is divided into a switching preparation stage, a switching execution stage and a switching completion stage; the resource allocation process of the network element is different in each switching stage, so the controller firstly recognizes the switching stage of the current base station; the parallel control module M10 performs step S2: after receiving the switching signaling in the switching stage, the network element controls the resource configuration process of the network element to be executed in parallel; the parallel execution of the resource allocation process can shorten the time length of the whole process, thereby improving the efficiency of base station switching and improving the experience of users when switching base stations.
After the parallel control module M10 completes step S2, the exception handling module starts a process of processing resource configuration, and the specific execution process is as follows:
s3: starting a timer, if at least one response time of the resource allocation response information exceeds the time of the timer, executing step S4; if the response time of all the resource allocation response messages does not exceed the time of the timer, executing step S5; wherein, the resource allocation response information is a signaling responding to the resource allocation request information;
S4: judging that the overtime abnormal condition occurs in the resource allocation process, and executing response overtime processing;
s5: when the network element receives all the resource allocation response information, closing the timer;
after the parallel control module M10 executes step S2, the exception handling module M20 monitors whether the whole parallel resource configuration process is performed normally through setting a timer, and the exception handling module M20 executes step S3: starting a timer, and waiting for resource allocation response information of each resource allocation request message to respond to the network element; the time set by the timer is the time of responding to all the resource allocation response information under normal conditions calculated in advance; if at least one of the resource allocation response messages is not returned to the network element within the time specified by the timer, the response of the resource allocation response message is overtime or failed, and the exception handling module M20 performs step S4: judging that the resource allocation process has overtime abnormal conditions and executing response overtime processing, thereby solving the problems of overtime response or failure response of the request encountered by the current resource allocation; if all the resource allocation response messages are returned to the network element within the time specified by the timer, the resource allocation process is successfully completed, so that the exception handling module M20 executes step S5, and when the network element receives all the resource allocation response messages, the timer is closed, and the parallel control module M10 and the exception handling module M20 successfully control the network element to complete the parallel execution of the resource allocation process. The exception handling module M20 may monitor the response failure and response timeout conditions of the resource configuration by setting a timer in the process of executing the resource configuration in parallel, and timely handle timeout exceptions.
As a preferred solution, the specific execution procedure of the exception handling module M20 in step S3 is as follows:
s31: starting a timer;
s32: after the network element receives the resource allocation response information, setting configured flag bits in the resource allocation response information and resource allocation request information of the resource allocation response information;
in the operation of "executing response timeout processing" in step S4, the specific execution procedure of the exception handling module M20 is as follows: according to the configured flag bit in step S32, the exception handling module M20 releases the resource allocation request information and the resource allocation response information with the configured flag bit.
The exception handling module M20 starts a timer, and when the network element receives the resource allocation response information, the exception handling module M20 sets configured flag bits in the resource allocation response information and the corresponding resource allocation request information, which represents that the resource allocation corresponding to the resource allocation request information is completed. When at least one response time of the resource allocation response information exceeds the time of the timer, the exception handling module M20 needs to locate all resources that have been configured according to the configured flag bit in step S32, and execute step S4: and releasing all the resource allocation request information and the resource allocation response information with the allocated flag bit, so as to avoid the residual unused resources in the network element.
Preferably, the parallel control module M10 further performs the following operation steps in the process of controlling the base station handover:
d1: identifying a terminal initiating the base station switching, and distributing a context for the terminal;
d2: and managing the process and the state of the terminal in the base station switching through the context of the terminal.
When a terminal initiates a base station switching, the parallel control module M10 identifies the terminal and distributes contexts for the terminal, and each context uniquely corresponds to the state of the terminal, so that the process and the state of the terminal in the base station switching can be managed through the context of the terminal, the step D1 should be executed before the step S1, and the parallel control module M10 is ensured to identify and manage each terminal, so that the terminals are not interfered with each other in the base station switching process; the step D2 may be performed at any stage of the handover of the base station after the step D1 is completed.
As a preferred solution, the specific execution procedure of the parallel control module M10 in step D1 is as follows: identifying the terminal through the identifier of the terminal, and distributing a context for the terminal; when any network element which is not uniquely identified with the terminal receives any handover instruction about the terminal, the parallel control module M10 performs step D11:
D11: and when any network element starts the resource allocation process of the terminal, the terminal and the network element are uniquely identified.
The specific execution process of the parallel control module M10 in step D2 is as follows: and in each resource allocation process, determining the context of each terminal through the unique identification, and further managing the process and state of the terminal in the base station switching through the context of the terminal.
The step D1 still needs to be performed before the step S1, the parallel control module M10 may perform the step D11 when any network element that does not perform unique identification with the terminal receives any handover command related to the terminal at any stage of base station handover after the step S1 is completed, and the parallel control module M10 may perform the step D2 only for the network element and the terminal with the unique identification because the unique identification in the step D11 is involved in the step D2, that is, for the same network element and terminal, the parallel control module M10 needs to perform the step D11 before performing the step D2.
Each terminal is provided with an identifier of the terminal, the parallel control module M10 can identify the terminal more accurately through the identifier of the terminal, and after context is allocated to the terminal, when any network element starts the resource allocation process of the terminal, the parallel control module M10 carries out unique identification on the terminal and the network element, namely, the state of the terminal switched at the current base station is identified through the resource allocation process of the network element, and the context of the terminal is processed. Therefore, after the unique identifier, when the network element receives any switching instruction, the parallel control module M10 can determine the context of the terminal through the unique identifier set in the network element, and perform the processing of base station switching on the context of the terminal while configuring resources, so as to better manage the base station switching of the terminal.
