Technical Field
The present invention relates to the field of wireless communication technologies, and in particular, to a method and an apparatus for keeping instance resources alive in a base station network element.
Background
With the increase of the base station processing traffic, the situation of hanging up of instance resources occurs between each processing unit of the base station in the cooperation process. As the processing unit operates, the dead instance resources accumulate, and the instance resources of the whole processing unit are exhausted in a long term, thereby causing the capacity and performance of the whole base station system to be reduced.
The keep-alive of instance resources among the existing multi-processing units is mainly realized in a unidirectional way. That is, alignment is performed from top to bottom or from bottom to top, and it cannot be guaranteed that in a specific scene, when a resource is hung up in a certain upper layer (or lower layer) processing unit, the lower layer (or upper layer) processing unit cannot find the resource in time, so that the resource of the instance hung up in the upper layer (or lower layer) is hung up. Once the example resource is hung up and cannot be found and cleared in time, the capacity of the whole base station is reduced, and the KPI index is seriously influenced. Currently, there is no robust and efficient processing method for instance resource hang-up between such multi-processing units.

Fig. 3 is a schematic diagram of system cooperation for example resource keep-alive in a base station network element according to an embodiment of the present invention, and as shown in fig. 3, the system cooperation includes a signaling processing unit, a base station resource processing unit, and a baseband processing unit.
Wherein the signaling processing unit: the system is responsible for receiving signaling messages from a network side, distributing various example resources according to signaling contents, sending base station resource configuration request messages to the base station resource processing unit, and storing the mapping relation between the base station example resources in the base station resources returned in the base station resource configuration response messages and the signaling example resources in the signaling processing unit. Meanwhile, the upper layer activity detection message is sent to the base station resource processing unit to carry out the keep-alive detection of the upper layer instance resource, and the upper layer activity detection message result returned by the base station resource processing unit is received.
Wherein the base station resource processing unit: receiving a base station resource allocation request message of the signaling processing unit, creating a base station instance resource, allocating a base station instance resource required in the base station resource allocation request message, and establishing a mapping relation between the base station instance resource of the base station resource processing unit and the signaling instance resource in the signaling processing unit. The signaling instance resource of the signaling processing unit and the base station instance resource of the base station resource processing unit are in a many-to-many relationship. After the base station resource processing unit completes resource configuration, a base band processing request message is sent to the base band processing unit, and the mapping relation between the base band instance resources in the base band subsystem returned in each subsystem response message of the base band processing unit and the base station instance resources in the base station resource processing unit is stored. After finishing all processing, the base station resource processing unit carries the established mapping relation between the base station instance resource of the base station resource processing unit and the signaling instance resource in the signaling processing unit in the configuration response message returned to the signaling processing unit. Meanwhile, the upper layer activity detection message sent by the signaling processing unit is received, and the lower layer activity detection message is sent to each subsystem in the baseband processing unit.
Wherein the baseband processing unit: the system comprises a plurality of subsystems, and tasks are processed independently among the subsystems. Each subsystem receives the base band processing request message of the base station resource processing unit, creates base band instance resources, and establishes a mapping relation between the base band instance resources of the base band processing unit and the base station instance resources in the base station resource processing unit, so as to bring the base station resource processing unit in a response message. The base band instance resource of each subsystem of the base band processing unit and the base station instance resource of the base station resource processing unit are also in a many-to-many relationship. Meanwhile, each subsystem receives a lower layer activity detection message sent by the base station resource processing unit and returns a lower layer activity detection failure message to the base station resource processing unit.
Firstly, a keep-alive mechanism between a signaling processing unit and a base station resource processing unit:
step 1, the signaling processing unit starts a timer S1, and sends activity detection messages to the base station resource processing unit at regular intervals t.
Step 2, when the base station resource processing unit receives the message, the base station resource processing unit matches the signaling instance resource according to the mapping relation between the base station instance resource of the base station resource processing unit and the signaling instance resource in the signaling processing unit, if the base station instance resource is not matched with the signaling instance resource, an activity detection failure message is returned to the signaling processing unit, and the step 3 is switched; and if the matching is successful, updating the system time stamp of the base station instance resource, and turning to the step 4.
And 3, when the signaling processing unit receives the example activity detection failure message returned by the base station resource processing unit, considering that the signaling example resource is hung up, and deleting the locally corresponding example resource.
And 4, starting a timer T1 by the base station resource processing unit, checking all base station instance resources at regular intervals of m, and if the absolute value difference between the latest system timestamp in the base station instance resources and the current system timestamp is greater than a threshold k, hanging the base station instance resources and deleting the base station instance resources.
The threshold k is calculated as follows:
k-m-offset value offset1, where 0< (offset 1< (3) >)
(offset value offset1 is due primarily to differences in processing capabilities among processing units or errors resulting from delays in messages).
Secondly, keep-alive mechanism between the base station resource processing unit and the baseband processing unit:
step 11, the base station resource processing unit starts a timer T2, and sends an activity detection request message to n subsystems in the baseband processing unit at regular intervals of s in a round-robin manner.
And step 12, after n subsystems in the baseband processing unit receive the activity detection request, reporting all current example resources of each subsystem to the base station resource processing unit.
And step 13, after the base station resource processing unit receives the instance resource message reported by the subsystem of the baseband processing unit, matching instance resources according to the established mapping relation between the baseband instance resources of the baseband processing unit and the base station instance resources in the base station resource processing unit. If the example resource reported by the subsystem of the baseband processing unit is not matched in the base station resource processing unit, sending a message for deleting the example resource to the corresponding subsystem of the baseband processing unit, and turning to step 14; if the example resource in the base station resource processing unit is not matched in the example resource reported by the subsystem of the baseband processing unit, marking the example resource as an abnormal example resource, counting the example resource, and turning to step 15.
And step 14, when the subsystem of the baseband processing unit receives the deletion message sent by the base station resource processing unit, deleting the instance resource corresponding to the subsystem.
Step 15, for example resources more than each subsystem in the baseband processing unit in the base station resource processing unit, adopting a timing counting strategy for processing, specifically as follows:
1) a period timer T3 is set, and the period interval is set to d.
2) And resetting all the marked abnormal instance resource counts in the base station resource processing unit.
3) The timer T3 times out, and it is counted whether the instance resource count in the base station resource processing unit exceeds the threshold c. Wherein the threshold c is calculated as follows:
c/(s × n) -deviation value offset2, where 0 <(s) > -offset 2 <(s) > -5
(offset value offset2 is due primarily to differences in processing power between processing units or errors due to delays in messages).
And if the example resource count in the base station resource processing unit exceeds the threshold c, the example resource in the base station resource processing unit is considered to be hung. At this time, the base station resource processing unit deletes the corresponding instance resource, sends the message of deleting the instance resource to other subsystems of the baseband processing unit, and sends the message of failing to detect the activity of the base station resource processing unit and the baseband processing unit to the signaling processing unit, informs the signaling processing unit to delete the corresponding instance resource, and returns to the step 2).
The following describes in detail the implementation of the example resource bidirectional keep-alive mechanism between multiple processing units in two scenarios with reference to fig. 3 to 5:
the first scenario is that a certain single board contains 9 subsystems.
1. The signaling processing unit starts a timer S1 and sends an activity detection message to the base station resource processing unit every 20 seconds.
2. When receiving the message, the base station resource processing unit matches the corresponding instance resource, if the instance resource is not matched, the base station resource processing unit returns an activity detection failure message to the signaling processing unit, and then the step 3 is carried out; and if the matching can be achieved, updating the system time stamp SysTicki of the base station instance resource, and turning to the step 4.
3. When the signaling processing unit receives the instance activity detection failure message returned by the base station resource processing unit, the signaling processing unit considers that the local signaling instance resource is hung up, and deletes the local corresponding signaling instance resource.
4. The base station resource processing unit starts a timer T1, checks all base station instance resources every 1 minute, and records the current time stamp as SysTickj. And setting the threshold k to be 1 minute, and if the current system time stamp SysTickj-SysTicki is more than 1 minute, considering that the base station instance resource is hung up, and deleting the base station instance resource.
5. The base station resource processing unit starts a timer T2, and sends activity detection request messages to 9 subsystems in the baseband processing unit in a round-robin manner every 5 s.
6. After 9 subsystems in the baseband processing unit receive the activity detection request, all current baseband instance resources of each subsystem are reported to the base station resource processing unit.
7. And after receiving the baseband example resource message reported by the subsystem of the baseband processing unit, the base station resource processing unit performs example resource matching. If the base band example resource reported by the subsystem of the base band processing unit is not matched in the base station example resource of the base station resource processing unit, sending a message for deleting the base band example resource to the corresponding subsystem of the base band processing unit, and turning to the step 4; if the example resource in the base station resource processing unit is not matched in the example resource reported by the subsystem of the base band processing unit, counting the base station example resource in the base station resource processing unit, and turning to the step 5.
8. And when the subsystem of the baseband processing unit receives the deletion message sent by the base station resource processing unit, deleting the locally corresponding baseband instance resource, and returning to the step 2.
9. The base station resource processing unit adopts a timing counting strategy to process more instance resources than each subsystem in the baseband processing unit, and the method specifically comprises the following steps:
1) a cycle timer T3 is started, and its cycle interval is set to 10 minutes.
2) All exception instance resource counts in the base station resource handling unit are clear 0.
3) And when the timer is overtime, counting whether the resource count of the base station instance in the base station resource processing unit exceeds a threshold c. According to a threshold calculation formula: c/(s × n) -deviation value offset2, where offset2 is 2, d is 10 minutes, s is 5 seconds, n is 9, and c is calculated 11 times.
And if the example resource count in the base station resource processing unit exceeds the threshold c, the base station example resource in the base station resource processing unit is considered to be suspended. At this time, the base station resource processing unit deletes the corresponding base station instance resource, sends a message of deleting the base station instance resource to the corresponding subsystem of the baseband processing unit, and sends a message of failing activity detection to the signaling processing unit, which informs the signaling processing unit to delete the corresponding signaling instance resource.
The second scenario is that a certain single board contains 8 subsystems.
1. The signaling processing unit starts a timer S1 and sends an activity detection message to the base station resource processing unit every 20 seconds.
2. When receiving the message, the base station resource processing unit matches the corresponding instance resource, if the instance resource is not matched, the base station resource processing unit returns an activity detection failure message to the signaling processing unit, and then the step 3 is carried out; and if the matching can be carried out, updating the system time stamp SysTicki of the base station instance resource, and turning to the step 4.
3. When the signaling processing unit receives the instance activity detection failure message returned by the base station resource processing unit, the signaling processing unit considers that the local signaling instance resource is hung up, and deletes the local corresponding signaling instance resource.
4. The base station resource processing unit starts a timer T1, checks all base station instance resources every 1 minute, and records the current time stamp as SysTickj. And setting the threshold k to be 1 minute, and if the current system time stamp SysTickj-SysTicki is more than 1 minute, considering that the base station instance resource is hung up, and deleting the base station instance resource.
5. The base station resource processing unit starts a timer T1, and sends activity detection request messages to 8 subsystems in the baseband processing unit in a round-robin manner every 5 s.
6. After 8 subsystems in the baseband processing unit receive the activity detection request, all current baseband instance resources of each subsystem are reported to the base station resource processing unit.
7. And after receiving the baseband example resource message reported by the subsystem of the baseband processing unit, the base station resource processing unit performs example resource matching. If the base band example resource reported by the subsystem of the base band processing unit is not matched in the base station example resource of the base station resource processing unit, sending a message for deleting the base band example resource to the corresponding subsystem of the base band processing unit, and turning to the step 4; if the example resource in the base station resource processing unit is not matched with the example resource reported by the subsystem of the base band processing unit, counting the base station example resource in the base station resource processing unit, and turning to the step 5.
8. And when the subsystem of the baseband processing unit receives the deletion message sent by the base station resource processing unit, deleting the locally corresponding baseband instance resource, and returning to the step 2.
9. The base station resource processing unit adopts a timing counting strategy to process more example resources than each subsystem in the baseband processing unit, and the method specifically comprises the following steps:
1) a period timer T3 is started, the period interval is set to 10 minutes, and the resource counts of all instances in the base station resource processing unit are initialized to 0.
2) The timer T3 times out, and it is counted whether the instance resource count in the base station resource processing unit exceeds the threshold c. According to a threshold calculation formula: the offset value offset2 is offset2 2, d 10 minutes, s 5 seconds, n 8, and c 13 times is calculated.
And if the base station instance resource count in the base station resource processing unit exceeds the threshold c, the base station instance resource in the base station resource processing unit is considered to be hung. At this time, the base station resource processing unit deletes the corresponding base station instance resource, sends a message of deleting the base station instance resource to the corresponding subsystem of the baseband processing unit, and sends an activity detection failure message to the signaling processing unit, which notifies the signaling processing unit to delete the corresponding signaling instance resource.
3) And clearing all the example resource counts in the base station resource processing unit. Returning to the step 2).
