Access control method and device of mobility management entity (MME) resource processing entity

Abstract

The invention discloses an access control method and an access control device of a mobility management entity (MME) resource processing entity. The method and the device are used for avoiding the phenomenon that the resource processing entity is suspended caused by instantly accessing a large number of stream control transmission protocol (SCTP) messages, efficiency is ensured, and the load of the MME resource processing entity is shared and protected by performing access control on a processing node of an MME network element at the same time. The method comprises the following steps of: at the starting time of each unit interval, determining the number of the SCTP messages which are to be accessed in the unit interval according to a determined unit interval and the number of the SCTP messages which are accessed and processed sequentially in a previous unit interval; and in each unit interval, accessing and processing the SCTP messages in a corresponding number according to the receiving sequence of the SCTP messages and the determined number of the SCTP messages which are to be accessed in the unit interval, wherein in a first unit interval, a preset number of SCTP messages access number are accessed.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an access control method and device for an MME resource processing entity. Background technique [0002] We know that when MME (Mobility Management Entity) resource processing is processing SCTP messages, if there are too many SCTP messages to be processed in an instant, the MME resource processing entity will crash, and in serious cases, the circuit may be burned. [0003] Especially after the MME resource processing entity is restarted, all base stations associated with it before the restart will send a large number of SCTP (Stream Control Transmission Protocol) INIT (initialization) messages to the MME resource through the processing node of the MME network element in a short period of time. The SCTP protocol stack of the processing entity will stop sending INIT messages only after the base station receives the returned response message. If the SCTP protocol sta...

[0002] We know that when MME (Mobility Management Entity) resource processing is processing SCTP messages, if there are too many SCTP messages to be processed in an instant, the MME resource processing entity will crash, and in serious cases, the circuit may be burned

[0003] Especially after the MME resource processing entity is restarted, all base stations that have established a coupling with it before the restart will send a large number of SCTP (Stream Control Transmission Protocol) INIT (initialization) messages to the MME resource through the processing nodes of the MME network element in a short period of time. The SCTP protocol stack of the processing entity will stop sending INIT messages only after the base station receives the returned response message. If the SCTP protocol stack cannot process these messages in time, the CPU resources of the MME resource processing entity will be exhausted, and eventually the MME The resource processing entity cannot process other messages and hangs

However, in the prior art, there is no protection mechanism for the instantaneous access of a large number of SCTP INIT messages
