Mobile network over loading control method

Abstract

The invention discloses a control method for overload of mobile network, which comprises: when detecting device jam or overload, determining business and / or signaling need to be limited; when as calling part, the terminal decides whether to start access request according to send information from network; or the terminal as called part, network side decides whether rejects other business request according to business and signaling type need to be limited. This method can distinguish and control to different business and signaling, use network more proper, and increases user satisfaction.

Description

technical field [0001] The invention relates to mobile network resource management technology, in particular to a mobile network overload control method. Background technique [0002] With the development of mobile communication, the introduction of competition mechanism and the improvement of network quality requirements, the service quality of mobile network becomes more and more important. The quality of network service is specifically reflected in network indicators such as congestion rate, call drop rate, and call quality. Among them, network congestion is a problem that every network operator will face. How to deal with congestion in order to alleviate congestion for users Many inconveniences caused by the normal communication of the mobile system are called problems that must be considered by the mobile system. [0003] Mobile network congestion includes a variety of situations: wide area wireless interface congestion, radio network controller (RNC) / base station cont...

AI Technical Summary

Problems solved by technology

[0006] Although the above mobile network access control mechanism alleviates the congestion or overload of the mobile network to a certain extent, it also has great defects, because the mobile network is divided into circuit domain (CS) and packet domain (PS). When the network is congested or overloaded, the situation of CS and PS congestion or overload is likely to be different. For example, the short message service and mobility management signaling in the CS domain are processed by the MSC server, and the voice service and circuit data service require a media gateway (MGW) Processing, when the MGW is congested or overloaded but the MSC server is not congested or overloaded, only the services related to the MGW need to be restricted, and the services and signaling unrelated to the MGW do not need to be restricted

In this case, the current mobile network access control mechanism cannot restrict the corresponding services and signaling according to specific services, but can only implement independent user access level restrictions on CS and PS respectively. Therefore, if the RNC / BSC The CS domain access control information is issued through the system broadcast message, which restricts all CS domain access requests initiated by some or all users in the area and responding to CS domain paging messages

[0007] Similar situations can also occur in the PS domain. For example, the packet service bearer processing resources in the GSGN / GGSN are insufficient, but the SGSN / GGSN signaling processing is normal; services without restricting user mobility management signaling and packet bearer services, however, the current mobile network access control mechanism cannot achieve this

[0008] From the above analysis, it can be seen that the defect of the existing technology is that the current mobile network overload control can only limit the user access level, but cannot limit the specific CS and PS services and signaling, resulting in User services and signaling that are not necessary to be prohibited are prohibited, affecting the normal use of the network
