Problems solved by technology

But at present, this mechanism only makes the following assumption: Even if an exception occurs, the instance process can still be completely released
In fact, the keep-alive mechanism does not take into account an abnormal situation: even if it is judged that there is a keep-alive loss, and the release operation is performed, but due to some unknown reasons, it is not released during the release process. The instance process, so that the instance resources cannot be released normally for a long time, and it is in a dead state, that is, the phenomenon of resource hanging (resource leakage) occurs, and the system cannot detect this, so it cannot perform further exception handling

Embodiment 1

[0039] In this embodiment, taking TD-RNC (the radio network controller of TD-SCDMA) as an example, the system principle block diagram for detecting abnormal instance resources in TD-RNC is shown in figure 2 middle.

[0040] Depend on figure 2 It can be seen that the system includes a wireless network subsystem 100 and an operation and maintenance subsystem 200; wherein: the wireless network subsystem 100 includes a UE instance control module 110 for creating or releasing each UE instance 120; the operation and maintenance subsystem 200 contains and The UE instance detection module 210 connected to the UE instance control module 110 is used to execute commands created and released by the UE instance control module; the UE instance detection module 210 has a built-in registry memory 2101 and a timer 2102 .

[0041] During the instance creation and release process, the UE instance detection module 210 not only saves or releases the GID identifying the UE instance in the regist...

Embodiment 2

[0052] The difference between this embodiment and embodiment 1 is only: figure 2 The timer 2102 of the UE instance detection module 210 in can also be made up of a group of timing units, such as Figure 4 Timing unit group 2102' in ; where each timing unit is set for the creation of a UE instance, and the timeout period can be set as the timing period of the timing unit. When the UE instance control module 110 creates a UE instance, the UE instance detection module 210 allocates a certain timing unit for it, records its identification number in the corresponding UE instance information item in the registry, and starts its timing operation; when the UE instance When the control module 110 releases the UE instance, the UE instance detection module 210 terminates the timing operation of the timing unit. If the system has not released the UE instance due to abnormal reasons, the timing unit will always operate until it overflows; when overflowing, the UE instance detection modul...

Abstract

The invention provides a system for detecting abnormal instance resources, which is applicable in an RNC. The system comprises a wireless network subsystem and an operation maintenance subsystem; the wireless network subsystem comprises a UE instance control module used for creating and releasing the UE instance; the operation maintenance subsystem comprises a UE instance detection module which is connected with the UE instance control module, and used for executing the command for creating and releasing the UE instance of the UE instance control module; wherein, a registry list and a timer are arranged in the UE instance detection module, and used for saving the information items of the global identifier GID and the UE instance, which marks the UE instance, in the registry during the processes of creating and releasing the UE instance, and detecting the information items of the UE instance on a regular basis, so as to detect the abnormal instance which is created overtime. The system has the advantages of flexible strategy and easy implementation, and brings no change in the basic flow of the prior mobile communication services.

Description

technical field [0001] The invention relates to wireless resource management technology in a mobile communication system, in particular to a detection system and method for wireless resource leakage. Background technique [0002] In the third generation mobile communication system, system resources are extremely precious. Leakage of system resources will not only affect the performance of the mobile communication network, but even lead to the collapse of the system. [0003] A radio network controller (RNC, Radio Network Controller) in a third generation mobile communication system usually allocates and releases instance resources frequently, so as to implement access and release of user equipment (UE, UserEquipment). [0004] The traditional UE instance resource detection mechanism is realized by the two-way keep-alive mechanism between instance processes, that is, both instance processes send keep-alive messages to each other at regular intervals to notify each other of t...
