Flow control method, apparatus and system for communication network

Abstract

The invention provides a flow control method, a device and a system for a communication network, wherein, the method comprises receiving a call signaling; sending routing information request to a called home location register; receiving response message returned by the home location register, wherein, the response information carries the priority of a called terminal and roaming numbers obtained from a called mobile switching center by the home location register; according to the priority of a calling terminal and the priority of the called terminal, whether a secondary calling is preferentially treated or not is determined. The embodiment of the invention can guarantee preferential treatment in different situation, such as calling a privileged user by a privileged user, calling a common user by a privileged user, and calling a privileged user by a common user, etc.

Description

technical field [0001] The present invention relates to the communication field, in particular to a flow control method, device and system of a mobile communication network. Background technique [0002] When holidays (such as New Year) come, or emergencies (such as terrorist attacks, natural disasters, etc.), often cause a sudden increase in communication network traffic. In the case of a sudden increase in traffic, as an emergency treatment, flow control is required to limit a certain proportion of calls to ensure the stable operation of the communication system. And under the impact of heavy traffic, it is necessary to ensure the smooth communication of special users (such as disaster relief command personnel). For this reason, it is necessary to give these special users higher communication rights, and these special users can be made privileged users with higher communication rights than ordinary users by setting user priorities. [0003] In the mobile communication sy...

Problems solved by technology

[0004] In the process of realizing the present invention, the inventor found that there are at least the following problems in the prior art: the existing flow control can only guarantee the call processing when the privileged user is the calling party, and if the ordinary user calls the privileged user, the call cannot be guaranteed. Priority treatment of

Moreover, the existing flow control method only carries the priority information of the calling terminal to the called side during inter-office calls. Since the roaming number has been allocated before, the release of the call will still occupy the roaming number resources, and the relay office During flow control, the previous processing has already occupied a certain amount of system processing capacity, that is, system resources
