Method and device for memory management

Abstract

The invention discloses a memory management method and device. The memory management method and device are used for fast recovering leaked memory when the memory is leaked, and therefore single board faults and service abnormity caused by memory leakage are avoided. The memory management method includes the steps that when a request message of applying for the memory from an application module user is received, a memory block is distributed for the application module user according to the request message, and record information indicating that the memory block is occupied by the application module user is set up; when it is determined that any memory block distributed for the application module user needs to be released, the memory block is released, and the record information indicating that the memory block is occupied by the application module user is deleted; when the application module user needs to be released, if it is determined that the record information indicating that the memory block corresponding to the application module user is occupied by the application module user exists, the recorded memory block occupied by the application module user in the record information is released, and the record information indicating that the memory block is occupied by the application module user is deleted.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a memory management method and device. Background technique [0002] During service transmission or cell switching in the communication system, application module users in the network equipment will frequently access and delete. Each application module user needs to maintain the information of multiple protocol entities, which involves the establishment and processing of multiple business processes. Delete. When a service is established, it is necessary to apply for a memory block for the service in the network device. When the service is deleted, it is necessary to release the memory block applied for the service in the network device. When a service is applied for due to a program error or other reasons When the memory blocks of the system fail to be released, memory leaks occur. When there are many memory leaks, it is easy to cause major problems such as board failures ...

AI Technical Summary

Problems solved by technology

In this solution, the duration threshold is difficult to determine. In some scenarios, the memory block may occupy a long time or has been occupied, for example: the community memory resource in the wireless network device, and the release of the memory in this solution has a lag, and the leaked memory needs to wait for the duration threshold before it can be released.

[0007] To sum up, none of the three solutions provided by the prior art can be used to solve the problem of memory leaks in network equipment. Application module users in network equipment are frequently accessed and deleted, and each application module user involves the establishment of multiple services. In the process of business deletion, due to program errors or other reasons, some memory blocks requested by application module users cannot be released, resulting in memory leaks, which in turn lead to single board failures, business abnormalities, and affect the normal use of network equipment
