Description
Technical field
The present invention relates to wireless communication field, relate in particular to a kind of jamming control method and equipment.
Background technology
Existing 3G (Third Generation) Moblie standardization body (3GPP) agreement has proposed mobile management congestion control (the APN based Mobility Management control) mechanism based on Access Point Name (APN).
According to the mobile management congestion control mechanism based on APN, network carries out the mobile management congestion control based on APN to the subscriber equipment (UE) of the special APN that contracted, when such UE sends mobile management (mobility management, MM) when request (request) is to network, network judges whether to start the mobile management congestion control based on APN, if, send the refuse information of this mobile management request to UE, and may in this refuse information, carry the information that mobile management is kept out of the way timer (mobility management back-off timer), UE keeps out of the way after the information of timer receiving mobile management, before keeping out of the way timer expiry, this mobile management no longer initiates to adhere to (attach) process except urgency traffic (emergency service) to network.Simultaneously, if network side maintains the context of this UE, can preserve mobile management back off time value this mobile management keep out of the way the time-out time of timer, before time corresponding to mobile management back off time value arrives, network can be refused the request of the attach except urgency traffic that this UE sends.
The judgement of above-mentioned network start mobile management congestion control based on APN according to as follows: the speed of mobile management Non-Access Stratum (NAS) message that one group of UE of this special APN that contracted sends has exceeded certain threshold value or has dropped under certain threshold value; And/or, the configuration in network management.
Existing 3GPP) agreement also proposed mobile management congestion control (the General NAS Mobility Management Congestion Control) mechanism of general NAS layer.
According to the mobile management congestion control of general NAS layer, in the time that UE sends mobile management request to network, if network side is not also for this UE sets up emergency bearing context (emergency bearer context), network judges whether to start the mobile management congestion control of general NAS layer, if, send the refuse information of this mobile management request to UE, and in this refuse information, carry the information that mobile management is kept out of the way timer, UE keeps out of the way after the information of timer receiving mobile management, start the local timer of keeping out of the way, before this keeps out of the way timer expiry, UE can not initiate any non-emergent business to network, the mobile management request of non-high priority or called service.Meanwhile, network side may preserve mobile management back off time value this mobile management keep out of the way the time-out time of timer, before time corresponding to mobile management back off time value arrives, network can be refused the mobile management request of any non-called service that UE sends; If network side has been set up emergency bearing context for this UE, network can be accepted any mobile management request of UE.
Keep out of the way timer run duration at mobile management, the UE of connected state can initiating updating of tracking area (TAU) process.
Above-mentioned judgement start general NAS layer mobile management congestion control according to as follows: network is in general overload (General Overload Condition).
For the common UE (being non-high-priority users) that does not set up emergency bearing business (emergency bearer service), keep out of the way timer in operation if there is mobile management, UE can initiate the mobile management request for emergency bearing business, but mobile management is kept out of the way timer, continuation keeps operation.UE keeps out of the way timer run duration at mobile management can initiate the mobile management request for emergency bearing business, the object of doing is like this to consider that network may recover from congestion state before mobile management is kept out of the way timer expiry, thereby can accept this mobile management request that UE sends.This mechanism is introduced in 3GPPTS24.301.
If but the mobile management request that UE initiates is service request (service request), TAU or Routing Area Update (RAU) request, the NAS layer of network cannot judge whether this mobile management request is for emergency bearing business so, therefore network is still likely refused this mobile management request, and this mechanism cannot be realized.
Realizing in process of the present invention, inventor finds to exist in prior art following technical problem:
The jamming control method that 3GPP proposes, keep out of the way timer and stop terminal to initiate mobile management request the network congestion in the situation that by issuing mobile management, simultaneously in network side preservation mobile management back off time value, for refusing the mobile management request of follow-up UE initiation.But the method may be brought following problem: if network is before time corresponding to mobile management back off time value arrives, recover from congestion state, the mobile management request that terminal is initiated so still can be refused by network, thereby makes normally access network of terminal.
