Description
Technical field
The present invention relates to the communications field, signaling reduction (Idle mode Signaling Reduction abbreviates ISR as) active control method, system and subscriber equipment (User Equipment abbreviates UE as) under a kind of idle pulley.
Background technology
The standardization effort group of third generation partner program is just being endeavoured research at present to packet switched core network (Packet Switched Core, abbreviate PS Core as) and global system for mobile communications wireless access network (Universal Mobile Telecommunication System RadioAccess Network, abbreviate UTRAN as) evolution, the mobile communication system of evolution is called the grouping domain system (Evolved Packet System abbreviates EPS as) of evolution.
Fig. 1 is global system for mobile communications (the Global System forMobile communications according to correlation technique, abbreviate GSM as)/universal mobile telecommunications system (UniversalMobile Telecommunications System, abbreviate UMTS as) and EPS network of network configuration diagram, as shown in Figure 1, comprise: UE101, the global system for mobile communications wireless access network (E-UTRAN) 102 of evolution, Mobility Management Entity (MobilityManagement Entity, abbreviate MME as) 103, GSM EDGE wireless access network (GSM EDGE Radio Access Network, abbreviate GERAN as)/UTRAN104, GPRS (General Packet Radio Service, abbreviate GPRS as) serving GPRS support node (Serving GPRS Support Node, abbreviate SGSN as) 105, (the Mobile Switching Center of mobile switching centre, abbreviate MSC as)/VLR Visitor Location Register (Visitor Location Register, abbreviate VLR as) 106, gateway (Serving Gateway, abbreviate S-GW as) and packet data network gateway (Packet DataNetwork Gateway, abbreviate PDN GW or P-GW as) 107, home subscriber server (Home Subscriber Server, abbreviate HSS as)/attaching position register (HomeLocation Register abbreviates HLR as) 108.
At the GSM/UMTS network, UE can carry out circuit switching (CircuitSwitching respectively, abbreviate CS as) and packet switching (Packet Switching, abbreviate PS as) adhere to/upgrade, at this moment, UE sends location area updating (Location Area Update respectively to GERAN/UTRAN, abbreviate LAU as) and Routing Area Update (Routing AreaUpdate, abbreviate RAU as) request message, MSC/VLR receives the LAU request message by GERAN/UTRAN, carry out adhering to/renewal process of CS territory, SGSN receives the RAU request message by GERAN/UTRAN, carries out adhering to/renewal process of PS territory.The mode that above-mentioned UE adheres to respectively/upgrades in CS territory and PS territory need take Radio Resource respectively and carry out the signaling exchange, introduces Gs interface between MSC/VLR and SGSN for this reason.When network work during at pattern I, UE upgrades by associating RAU/LAU process, set up the Gs association between MSC/VLR and the SGSN, as MSC/VLR because audio call, short message (Short Message Service, abbreviate SMS as) etc. during CS service needed paging UE, MSC/VLR carries out paging by SGSN; When network work during at pattern II/III, UE carries out RAU and LAU process respectively, because during CS service needed paging UE such as audio call, short message, MSC/VLR carries out paging according to the UE current position information of wherein preserving by the A/IU-CS interface as MSC/VLR.When MSC/VLR when the A/IU-CS interface receives the location area updating request message, Gs incidence relation information is with deleted.At synchronization, same UE only exists a Gs association or A/IU-CS interface to activate among the MSC/VLR.
The EPS network has only the PS territory, and it is IMS over IP that UE inserts a kind of implementation of carrying out speech business at E-UTRAN, and this mode need be disposed the IMS system; Another kind of implementation is circuit domain dropping (CS Fallback in EPS abbreviates CSFB as), and this mode does not need to dispose the IMS system, but realizes by introduce the SGs interface between MME and MSC/VLR.It is to transmit short message (SMS over IP) by IP that UE inserts a kind of implementation of carrying out short message service at E-UTRAN, and this mode need be disposed IMS network elements such as IP-SM-GW; Another kind of implementation is to transmit short message (SMS overSGs) by SGs, realizes by introduce the SGs interface between MME and MSC/VLR.
The implementation method of CSFB is: when UE inserts the E-UTRAN network, unite and adhere to (attach) or associating tracing section updating (Tracking Area Update, abbreviate TAU as) and LAU, between MME and MSC/VLR, set up the SGs association (promptly, in MME, preserve MSC/VLR number or address information, in MSC/VLR, preserve MME number or address information).Follow-up, MSC/VLR receives and calls out when needing paging UE, sends out beep-page message by the SGs interface to MME according to SGs related information wherein, and MME sends to UE by E-UTRAN with this CS service paging after receiving this beep-page message.After the UE paging is arrived, fall flow process accordingly after rise, UE carries out call establishment from GERAN/UTRAN network insertion and MSC/VLR, thereby converses.When the user makes a call, also be by corresponding falling process, UE falls back to GERAN/UTRAN from E-UTRAN and inserts.Call out the implementation method of irrelevant supplementary service (CallIndependent Supplementary Services), location service CS business such as (Location Services abbreviate LCS as) and call out similar.
Implementation method and the CSFB of SMS over SGs are similar, when difference is that MME receives the beep-page message of the short message service that MSC/VLR sends, if UE is in Idle state in MME, MME carries out the paging of PS by E-UTRAN, paging is behind UE, UE does not need to fall back to GERAN/UTRAN and inserts, but reside in E-UTRAN, transmit content of short message and status report message by the SGs interface between MME and the MSC/VLR, transmit content of short message and status report message by signaling between UE and the MME.If when MME received the paging of short message service from MSC/VLR, UE was in connected state in MME, existed signaling to be connected between UE and the MME this moment, and except MME did not need paging UE, the flow process of other flow process and above-mentioned Idle state was identical.SMS over SGs requires can transmit content of short message and status report message between MME and the MSC/VLR.
When introducing the SGs interface, the correlation technique regulation, at synchronization, the user only exists related or Gs association of a SGs or A/IU-CS interface to activate in MSC/VLR.
When E-UTRAN disposes, there is the common zone that covers of GERAN/UTRAN and E-UTRAN, at this moment, in order to reduce UE network selection and initiate registration process back and forth between GERAN/UTRAN and E-UTRAN, the standardization effort group of third generation partner program has defined ISR, its main thought is that UE registers in SGSN and MME simultaneously, SGSN and MME preserve user context information, also be kept at the log-on message of two networks among the UE, follow-uply like this when need selecting, UE just no longer carries out TAU and RAU process between two networks, unless the route district at the current place of UE does not have the tracking area at registration or current place not in the tracking area tabulation of having registered.If do not activate ISR, when UE changes connecting system, always initiate TAU or RAU at every turn.Under the situation that ISR activates, because UE when changing connecting system, do not initiate to upgrade, when UE is under the Idle state, network can't know that UE is current at which connecting system, therefore needs the UE of paging simultaneously at SGSN and MME.
Fig. 2 be according to the ISR of correlation technique activate, SGs activates, UE is in Idle state in MME, the interaction flow schematic diagram of MME when MSC/VLR receives the paging of CS business, as shown in Figure 2, this paging interaction flow comprises:
202, MSC/VLR initiates the paging of CS business to MME by the SGs interface.
204, MME is according to the positional information of the UE that wherein preserves and the positional information in the beep-page message, and one or more eNodeB by the place initiates the paging request to UE.
206, because ISR activates and UE is in Idle state in MME, in fact UE may insert at GERAN/UTRAN, and MME transmits the beep-page message of the CS business of coming from MSC/VLR to SGSN according to the information of the SGSN that wherein preserves.
208, SGSN initiates the paging of CS business according to the positional information of UE wherein and the positional information in the beep-page message to UE by the GERAN/UTRAN at place.
By above-mentioned flow process, UE is arrived in the MSC/VLR paging, thereby can realize CS business such as calling, short message.
When EPS network design and application, can there be a kind of network design scene as shown in Figure 3, do not dispose IMS, MSC/VLR 1 is the MSC of traditional GSM/UMTS, all CS business such as support call, short message are not supported SMS over SGs; MSC/VLR2 only supports SMS over SGs, does not support the function of CSFB and traditional MSC, such as voice call control etc.
Below in conjunction with Fig. 3 problem scenes 1 is described in detail, suppose among the UE use and voice are provided with Set For Current and are voice preferential (voice centric), UE supports SMS overSGs, may support CSFB.Under network design scene shown in Figure 3, exist following situation can cause when calling out MSC/VLR can't paging to UE, thereby call business can't be realized.
The first step, user's start or insertion subscriber card etc., UE inserts at GERAN/UTRAN and adheres to.UE unites and adheres to (attach) or carry out LAU and RAU respectively according to current network pattern and terminal type, and UE carries out the CS registration at MSC/VLR 1.MSC/VLR 1 carries out the position renewal and obtains user contracting data to HSS/HLR.The MSC information at the current place of UE of writing down in the information of this UE among the HSS/HLR is the information of MSC/VLR 1.Adhere to if unite, set up the Gs association between MSC/VLR 1 and the SGSN, MSC/VLR 1 receives audio call, can paging arrive UE by Gs interface.If carry out LAU and RAU respectively, positional information and A/IU-CS interface that MSC/VLR 1 preserves the current place of user activate, MSC/VLR 1 receives audio call, can paging arrive UE according to the UE current position information of wherein preserving by the A/IU-CS interface.
In second step, UE is because wireless signal strength changes or the user reason such as moves and inserts from E-UTRAN.When UE inserts associating TAU/LAU from E-UTRAN, succeed in registration at MME, MME is that UE selects MSC/VLR 2 to carry out the CS registration, sets up the SGs association between MME and the MSC/VLR 2.In the TAU/LAU process, ISR activates, and MME indication ISR in associating TAU/LAU response message activates, and UE is provided with the corresponding sign of ISR after receiving this response message.MSC/VLR 2 carries out the position renewal and obtains user contracting data to HSS/HLR.The MSC information at the current place of UE of writing down in the information of this UE among the HSS/HLR is changed into the information of MSC/VLR 2 from the information of MSC/VLR 1, and HSS/HLR sends cancel location message to MSC/VLR 1, and the data of MSC/VLR 1 this UE of sign are data invalid or that delete this UE.Because MSC/VLR 2 does not support CSFB, only support SMS over SGs, thereby MME can indicate the current just SMS over SGs of UE to succeed in registration in the associated update response message, UE will according to use in self and voice are provided with Set For Current be voice preferentially or high priority data (data centric) determines subsequent operation.If wherein Set For Current is that voice are preferential, UE will insert to GERAN/UTRAN from the E-UTRAN gravity treatment so.
In the 3rd step, the UE gravity treatment inserts to GERAN/UTRAN.At this moment, if UE inserts from the GERAN/UTRAN network area of having registered, RA/LA does not change, because ISR activates, UE can not initiate associating RAU/LAU or LAU.The MSC information at the current place of UE of writing down in the information of this UE among the HSS/HLR so remains the information of MSC/VLR 2, rather than the information of the UE MSC/VLR 1 that should register under GEARN/UTRAN.When UE resides in this RA/LA that has registered zone, if the user under this UE has a calling as the called subscriber, in calling out routing procedure, HSS/HLR will return the information of MSC/VLR 2, calling is routed to MSC/VLR 2 with mistake, and can't be routed to MSC/VLR 1, cause calling can't arrive UE.
In problem scenes 1, the user is unreachable when also existing another kind of possible situation also can cause exhaling eventually.UE at first adheres at GERAN/UTRAN, unites TAU/LAU at E-UTRAN then, and what be provided with among the UE when supposing associating TAU/LAU is high priority data, associated update success so, and ISR activates, and sets up the SGs association between MSC/VLR 2 and the MME.Follow-up when UE when E-UTRAN inserts wherein use and the voice setting to be revised as voice from high priority data preferential, UE can initiate the associated update process and insert to GERAN/UTRAN according to the gravity treatment as a result of associated update then.If UE registered at the RA/LA that GERAN/UTRAN inserts, UE can not initiate associating RAU/LAU or LAU process so.In this UE operating process, also exist when UE is follow-up to reside in this RA/LA zone of having registered untouchable problem of user when exhaling eventually.
The network design scene of the problems referred to above scene 1 is the situation that MSC/VLR 2 does not support CSFB, also there is another network design scene (being called problem scenes 2), MSC/VLR supports CSFB, just MME does not support CSFB, according to correlation technique, in calling out routing procedure, calling can be routed to MSC/VLR, MSC/VLR sends to MME by the SGs interface, because MME judges that UE is the combined registering of SMS over SGs only, can refuse the paging of the CS business such as audio call of MSC/VLR transmission, thereby may cause the result identical with problem scenes 1, that is, the user is unreachable when audio call is carried out in the RA/LA network area that the follow-up GERAN/UTRAN of retracting of UE has registered.
In the problems referred to above scene, voice call service not only, other CS business except short message for example, may exist also that the user is unreachable when professional can't carry out professional problem when network is initiated thereby call out irrelevant supplementary service, LCS etc.Have only short message service after being routed to MSC/VLR 2, can paging UE by flow process shown in Figure 2.
