Description

A kind of circuit switching (CS) method for processing business, device and network system
Technical field
The present invention relates to the communications field, relate in particular to a kind of circuit switching (CS) method for processing business, device and network system.
Background technology
Evolved packet system (Evolved Packet System, be called for short EPS) be third generation partner program (3rd Generation Partnership Project, be called for short 3GPP) at the second generation (The Second Generation, be called for short 2G) mobile communications network GSM/EDGE (Global System of Mobile Communication/Enhanced Data Rate forGSM Evolution, global system for mobile communications/enhanced data rates for gsm evolution technology) and the third generation (The Third Generation, be called for short 3G) mobile communications network UMTS (Universal Mobile Telecommunications System, universal mobile telecommunications system) basis on release.EPS network comprises evolved universal mobile communication system land radio access web (Evolved Universal Mobile Telecommunication System TerritorialRadio Access Network, be called for short E-UTRAN) and evolution block core net (EvolvedPacket Core Network is called for short EPC).Based on (the Mobile Switching Center/Visitors LocationRegister of mobile switching center/visitor location register in existing 2G/3G network, be called for short MSC/VLR) and mobile management entity (Mobility ManagementEntity, be called for short MME) between SGs interface function, 3GPP has proposed " circuit domain dropping " (CS Fallback, be called for short CSFB) technology and SGs short message transmission technology (ShortMessage Service over SGs is called for short SMS over SGs).CSFB technology makes subscriber equipment (the User Equipment under E-UTRAN covering, be called for short UE) in the time of needs treatment circuit exchange (Circuit Switched is called for short CS) speech business, get back to the finishing service processing of 2G/3G network C S territory by E-UTRAN; SMS over SGs technology allows and resides in UE under E-UTRAN and reuse existing CS territory equipment and realize the transmission of CS short message.
In above-mentioned CSFB and SMS over SGs mechanism, reside in E-UTRAN and support the UE of CSFB and/or SMS over SGs need to initiate when combined registering flow process is implemented to EPC network packet exchange (Packet Switched is called for short PS) territory and 2G/3G network C S territory to register.Successfully realizing after combined registering, the CSFB business of up-downgoing and the short message service of up-downgoing could normally be initiated.
Idle state signaling saving (Idle mode Signalling Reduction the is called for short ISR) mechanism of introducing 3GPP reduces UE and carries out back and forth the frequent a large amount of invalid position renewal signaling that causes and the signaling traffic load of air interface of switching in the overlapping covered or neighboring coverage areas of different radio Access Network.ISR is in the time of activated state, and MME, after the beep-page message of receiving from MSC/VLR, initiates beep-page message by E-UTRAN to UE, carries the instruction of PS territory in beep-page message.Simultaneously, MME is to associated service universal packet wireless business business (GeneralPacket Radio Service, GPRS) support node (Serving GPRS Support Node, be called for short SGSN) transmission paging indicating message, SGSN initiates beep-page message by wireless access network to UE, in beep-page message, carry the instruction of CS territory, UE carries out corresponding action according to the paging identify label in beep-page message and territory instruction.
When stating in realization ISR and activating in the process of CS service call, inventor has found that the MME of ISR association resets restarts the existing problem of rear prior art.MME reset restart after, alternatively, MME can notify associated MSC/VLR its restarted.MSC/VLR, after knowing that MME is restarted, alternatively, still can keep the SGs association of UE in activated state.In addition, MME can proactive notification registration UE and associated SGSN its restarted, therefore UE thinks that it still keeps the combined registering state in PS territory and CS territory.SGSN can know that associated MME resets and restarted by surveying mechanism, and restart but SGSN can not detect MME in time, this is (being generally 60 seconds) that exists predetermined detect cycle to cause due to this detection mechanism.Now, if there is descending (Mobile Terminated, be called for short MT) CS service call, MSC/VLR can first send beep-page message by SGs interface to associated MME, but reset and restart because of this MME, there is no the contextual information of UE, therefore MME can eat dishes without rice or wine to use IMSI to be initiated to the PS paging of UE, but can not send paging instruction to associated SGSN.Because current UE resides in 2G/3G network, therefore MME can not receive the page response from UE, finally cause MSC/VLR to stop SGs interface paging, cause mouth-to-ear delay even failed.
Meanwhile, when stating in realization ISR and activating in the process of CS service call, inventor has also found that the SGSN of ISR association resets restarts the rear existing existing problem of technology that realizes.After SGSN resets and restarts, can proactive notification registration UE and associated MME its restarted, therefore UE thinks that it still keeps the combined registering state in PS territory and CS territory, MME still thinks ISR maintenance activation.MME can know that associated SGSN resets and restarted by surveying mechanism, and restart but MME can not detect SGSN in time, this is (being generally 60 seconds) that exists predetermined detect cycle to cause due to this detection mechanism.Now, if there is descending (MobileTerminated is called for short MT) CS service call, MSC/VLR can first send beep-page message by SGs interface to associated MME.Because ISR activates, MME sends paging instruction to associated SGSN in sending to UE the paging of eating dishes without rice or wine.Because current UE resides in 2G/3G network, therefore MME can not receive the page response from UE, because resetting, SGSN restarts simultaneously, SGSN, receive after paging instruction not can paging UE, finally causes MSC/VLR to stop SGs interface paging, causes mouth-to-ear delay even failed.
In a word, in the time that ISR activates, no matter be that the MME of ISR association resets and restarts or after the SGSN of ISR association resets and restart, finally can cause MSC/VLR to stop SGs interface paging, and then cause mouth-to-ear delay even failed.
