Description
Technical field
(Evolved Packet System EPS), particularly relates at EPS and is linked into circuit domain (Circuit Switched Domain, CS) the position method for updating and the device of communication system to the present invention relates to the grouping system of evolution.
Background technology
As shown in Figure 1, be a kind of existing mobile communication network schematic diagram of third generation partner program (3GPP) tissue definition.This mobile communications network comprise Radio Access Network (Radio AccessNetwork, RAN) and core network (Core Network, CN) two parts.Wherein, RAN comprises base station (as BTS/NodeB) and base station controller (as BSC/RNC).CN from be divided in logic circuit commutative field (Circuit Switched Domain, CS) and packet-switched domain (Packet SwitchedDomain, PS).The main processed voice business in CS territory, Packet Service is mainly handled in the PS territory.The signaling plane controlled entity in CS territory is mobile switching centre/Visited Location Registor (Mobile SwitchingCenter/Visiting Location Register, MSC/VLR), the signaling plane controlled entity in PS territory is Serving GPRS Support Node (Serving GPRS Support Node, SGSN), SGSN can link to each other by Gs interface with MSC/VLR.
In order to tackle the challenge of wireless broad band technology, keep the leading superiority of 3GPP network, 3GPP the end of the year 2004 formulated the Long Term Evolution plan (Long Term Evolution, LTE).Except the research to wireless access network evolution, 3GPP also will carry out the evolution work of system architecture aspect, and with its be defined as System Architecture Evolution (System Architecture Evolution, SAE).Therefore whole plan is divided according to structure and also can be divided into two parts: wireless side (being LTE) and network side (being SAE).At present, 3GPP has determined the LTE/SAE system architecture, and with SAE rename grouping system into evolution (Evolved Packet System, EPS).The signaling plane controlled entity of evolution packet network core net be Mobility Management Entity (Mobility Management Entity, MME).A kind of typical EPS framework as shown in Figure 2.
And for the 2G or the operator in 3G epoch, built up ripe circuit domain (CS) network, abundant voice class business and part value-added service is provided.Therefore in the LTE/SAE evolution process, how to make full use of existing CS network, the investment of protection operator, and reduce the networking cost of operator as far as possible and accelerate professional speed to introduce just of crucial importance to operator.
As shown in Figure 3, be the schematic diagram of the packet network access CS network of existing a kind of evolution.It is to provide Iu-CS interface by adopting MME and S-GW to simulate RNC jointly to the MSC in CS territory, eNodeB, MME and gateway (Serving Gateway, S-GW) constitute the Access Network in CS territory jointly, reuse the purpose that the CS network is finished speech business thereby reach.
As shown in Figure 4, be the schematic diagram of the packet network access CS network of existing another kind of evolution.It is to adopt the grouped data network gateway of UE by evolution packet network (Packet Data NetworkGateway P-GW) is connected to the MSC in CS territory, and this moment, UE can send to MSC by MME to the signaling in CS territory, also can send to MSC by P-GW.
In traditional 3GPP mobile communications network, need to initiate register flow path after the UE start to network, go up registration present located lane place at core network signalling face controlled entity (MSC/VLR or SGSN), UE also needs to write down current network side appointed positions district simultaneously.Specifically, need on MSC/VLR, register the residing Location Area Identification of UE (Location Area Identity, LAI), registration UE residing Routing Area Identifier on SGSN (Route Area Identity, RAI).Insert the base station of side and can broadcast present located lane place or route district information to UE, UE compares the lane place of receiving or the lane place or the route district information of route district information and storage, if change has taken place in the lane place, then be initiated to the location area updating flow process of MSC; If change has taken place in the route district, then be initiated to the Routing Area Update flow process of SGSN.
In the packet network EPS of evolution, more than processing is similar, but change has been taken place in the definition of lane place, is referred to as " tracking area " (Tracking Area).The present located tracking area information also can be broadcasted in base station among the LTE, and UE compares the tracking area information received and the tracking area information of storage, if change has taken place tracking area, then is initiated to the tracing section updating flow process of MME.
The more new technological process of lane place, route district and tracking area can also periodically carry out, promptly behind relevant timer expiry, even the residing lane place of UE, route district or tracking area do not change, UE also can initiatively initiate periodic lane place, route district or tracing section updating to network and handle.
In this article, described term " position " refers to the residing zone of subscriber equipment in the mobile communication, includes but not limited to route district (RA), lane place (LA) and tracking area (TA); And " positional information ": the relevant information of expression subscriber equipment present position includes but not limited to Location Area Identification (LAI), Routing Area Identifier (RAI) and tracking area identification (TAI); " position renewal " refers in the mobile communication when mobile on the subscriber equipment occurrence positions, the process of updating position information of user equipment includes but not limited to that location area updating, Routing Area Update, tracing section updating, joint route area/location (RA/LA) upgrade and unite to follow the tracks of that area/location (TA/LA) upgrades etc.; " position updating request " refers to ask to carry out the process that the relevant position is upgraded, and includes but not limited to location area updating request, Routing Area Update request, tracing section updating request, joint route area/location (RA/LA) update request and unites tracking area/location (TA/LA) update request etc.
There are two kinds of implementation methods in the location area updating process of carrying out UE at present in mobile communications network, a kind of is independent CS location area updating flow process, and also having a kind of is to utilize more new technological process of joint route area/location (RA/LA) that the Gs interface that exists between SGSN and the MSC/VLR carries out.The main distinction of two kinds of methods is, the former is connected to the location area updating processing that MCS/VLR finishes CS by the Access Network of CS, the latter is when then the Access Network by PS is connected to SGSN and finishes Routing Area Update, and the location area updating that is accomplished to the CS territory by the Gs interface between SGSN and the MSC/VLR is handled.Below in conjunction with Fig. 5 to existing joint route area/location more new technological process describe.
Step S51, after UE detects route district or lane place and changes, send the Routing Area Update request message to SGSN, wherein, carry the information of the type of this renewal of sign, promptly unite more new logo of RA/LA.
After step S52, SGSN receive this message, initiate the authorizing procedure to UE, this flow process is optional flow process.
(Home Location Register HLR) initiates to upgrade the position flow process, finishes the registration of SGSN to HLR, and obtains the subscription data of user in the PS territory to attaching position register for step S53, SGSN.
Step S54, SGSN send location update request message by Gs interface to MSC/VLR, and instruct MS C/VLR carries out the position and upgrades processing.
Step S55, MSC/VLR initiate to upgrade the position flow process to HLR, finish the registration of MSC/VLR to HLR, and obtain the subscription data of user in the CS territory.
Step S56, MSC/VLR send the position by Gs interface to SGSN and upgrade and accept message, can comprise in this message MSC/VLR be the Temporary Mobile Subscriber Identity redistributed of UE (TemporaryMobile Subscriber Identity, TMSI).
Step S57, SGSN send Routing Area Update to UE and accept in the message, can comprise in this message SGSN be the packet TMSI redistributed of UE (Packet TMSI, P-TMSI) and MSC/VLR be the TMSI that UE distributes.
If step S58 has redistributed TMSI or P-TMSI for UE, UE returns Routing Area Update to SGSN and finishes message.
Redistributed TMSI if step S59 MSC/VLR is UE, then SGSN sends the TMSI Reallocation Complete message by Gs interface to MSC/VLR.
Flow process among Fig. 5 is able to operate as normal needs at first to satisfy two conditions: 1) base station is simultaneously to UE broadcasting Routing Area Identifier and Location Area Identification; 2) network can obtain the present located Location Area Identification by Routing Area Identifier.
But these two conditions can not be met in the packet network of evolution.The evolution packet network acquiescence is not insert existing circuit domain core net by access network base stations at present, therefore only needs the broadcasting tracking area identification, and does not need broadcast location area.And in tracking area identification definition, do not need to consider and the contact of existing Location Area Identification and Routing Area Identifier, therefore can not obtain the present located Location Area Identification by tracking area identification.
So, insert traditional circuit domain at the packet network that utilizes evolution, finish under the circuit domain business scene, because the Access Network of evolution packet network can not be to UE broadcast location area information, cause UE can not perceive the variation of lane place, therefore can not adopt the location area updating processing of normally finishing circuit domain as the method for Fig. 5.

Described EPS TA List is the TA List of the EPS network that distributes according to the residing TA of current UE in the EPS network, when UE is mobile in this EPS TA List, even variation has taken place TA, does not also need the initiating updating of tracking area flow process.
Can comprise at least one TA among the described TA List, the LA position that this TA List and the LAI that obtains from MSC/VLR are corresponding is identical.When UE is mobile in this TA List,, do not need to initiate the location area updating flow process even variation has taken place TA yet.
EPS TA List with the corresponding TA List of LA in the TAI that comprises can be identical, also can be different.
To have distributed new S-TMSI or MSC/VLR be that UE has distributed new TMSI if step S97 MME is UE, and then UE sends tracing section updating to MME and finishes message.
Distributed new TMSI if step S98 MSC/VLR is UE, then MME sends the TMSI Reallocation Complete message to MSC/VLR.
This flow process is that the TA/LA that UE initiates to unite more finishes in the new technological process, upgrades if the UE indication network only carries out the position in CS territory, and the tracing section updating that does not then carry out in the EPS network is handled, and does not promptly comprise step S92.Or, UE more in the new technological process (promptly do not comprise step S93～S95) when just initiating independent TA.More than in two kinds of scenes, the tracing section updating that MME sends to UE accepts also can comprise in the message TA List information of UE present located LAI and LA correspondence.
The mapping table of LAI described in the embodiment of the invention and TA List can dispose in MME, also can be configured in the data center in the network, after MME starts, can initiatively obtain the mapping table of this LAI and TA List, or obtain the mapping table of this LAI and TA List by related procedure to this data center; When this mapping table changed, data center also can initiatively send to MME with new mapping table.For example, this data center can be HLR/HSS.The mapping table of LAI and TA List is configured among the HLR/HSS, MME can obtain the mapping table of LAI and TA List from HLR/HSS when upgrading the position flow process with HLR/HSS, or obtain the mapping table of LAI and TA List after MME starts to HLR/HSS by special signaling.
As packet network acquisition with the current LA corresponding TA List of UE from evolution, and behind the optionally current LAI, when UE adopt the described method of embodiment to detect that current lane place has taken place to change or periodic location area updating timer expiry after, can adopt independent location area updating flow process shown in Figure 7 or associating TA/LA shown in Figure 9 more new technological process finish packet network by evolution to the location area updating flow process in CS territory.
If do not do specified otherwise, the location area updating flow process refers to the more general designation of new technological process of independent location area updating flow process described here and associating TA/LA.
Wherein, concrete step and aforementioned to Fig. 7 and roughly the same to the description of Fig. 9, different once places is mainly described below:
See also Fig. 7 again, UE is by collecting the location updating message of subscriber equipment, detects that current lane place changes or periodical location area upgrades timer expiry, judges that then needing to initiate the position upgrades, in the present embodiment, carrying out independent location area updating flow process comprises:
Step S71, UE send the location area updating request message to MME, can comprise the LAI formerly (old LAI) and/or the corresponding TA List of UE storage in this message.ENodeB can carry the residing TAI of current UE when transmitting this message to MME.
Whether the current lane place of UE detection changes and adopts the used method of the foregoing description, be that subscriber equipment receives the current TAI information that the evolution packet network base station is broadcasted, and whether be included in advance according to TAI information among the TA List (corresponding to LAI formerly) of storage, whether change to judge its present position-region.If current TAI in the TA List of the LA correspondence of storing, does not illustrate that then variation has taken place in the lane place, then judging needs to initiate the location area updating flow process.
After step S72, MME receive this location area updating request message, obtain LAI formerly and the current LAI of UE.For the LAI formerly of UE, MME can obtain according to following dual mode:
1) if this location area updating request message has comprised the LAI formerly of UE record, then directly uses this LAI formerly; Perhaps
2) if this location area updating request message has comprised the pairing TA List of LAI formerly, then MME obtains corresponding LAI formerly according to LAI with the corresponding relation of TA List.
For the current LAI of UE, then MME utilizes the UE present located TAI that eNodeB provides, and according to the correspondence table of LAI and TA List, finds the affiliated TA List of this TAI, and then obtains corresponding LAI.
Subsequent step is identical with aforesaid step S73～S77, does not describe in detail at this.
See also Fig. 9 again, UE is by collecting the location updating message of subscriber equipment, detects that current lane place changes or periodical location area upgrades timer expiry, judges that then needing to initiate the position upgrades, in the present embodiment, unite TA/LA more new technological process comprise:
Step S91, UE send the tracing section updating request message to MME, can comprise the LAI formerly and/or the corresponding TA List of UE record in this message.ENodeB can carry the residing current TAI of current UE when transmitting this message to MME.
Whether the current lane place of UE detection changes and adopts the used method of the foregoing description, be that subscriber equipment receives the current TAI information that the evolution packet network base station is broadcasted, and whether be included in according to TAI information among the TA List of UE storage, judge whether its present position-region changes.If current TAI in the TAList of storage, does not illustrate that then variation has taken place in the lane place, need to initiate the location area updating flow process.
If this moment, UE also needed the initiating updating of tracking area flow process, then UE needs indication network initiating updating of tracking area and location area updating processing simultaneously; Otherwise the location area updating that only needs indication network to be initiated to the CS territory is handled.Can to be UE carry updating type sign cell at the tracing section updating request message to indicating mode, and the TA/LA that comprises associating is new logo or LA new logo more separately more.
Overtime when the periodical position renewing timer of UE, also can initiate this associated update flow process, type can be upgraded for period L A.
After step S93, MME receive this tracing section updating request message, obtain the LAI (promptly formerly LAI) and the present located LAI (being current LAI) at the original place of UE.For the LAI formerly of UE, MME can obtain according to following two kinds of methods:
1) if this tracing section updating request message has comprised the LAI formerly of UE record, then direct priority of use LAI; Perhaps
2) if this tracing section updating request message has comprised the pairing TA List of LAI formerly, then MME obtains corresponding LAI formerly according to LAI with the corresponding relation of TA List.
For the current LAI of UE, then MME utilizes the UE present located TAI that eNodeB provides, and according to the correspondence table of LAI and TA List, finds the affiliated TA List of this TAI, and then obtains corresponding current LAI.
Other steps are identical with step S92, step S94～S98, do not describe in detail at this.
In other embodiments of the invention, subscriber equipment and Mobility Management Entity can also take other mode to judge whether current lane place variation has taken place.For example, adopt following mode in one embodiment:
LAI is made up of MCC, MNC and LAC according to the agreement regulation, i.e. LAI=MCC+MNC+LAC; And TAI is made up of MCC, MNC and TAC, i.e. TAI=MCC+MNC+TAC.As long as therefore can go out the information of LAC from the TAC direct derivation, then UE just can go out current LAI information by current TAI information inference.
Method one: in the ad-hoc location of TAC, fill in corresponding LAC information.First byte or bit such as TAC begin to fill in LAC; The relevant position just can obtain LAC information from the TAC field.
The value of method two: TAC is derived corresponding LAC by a definite algorithm.Preceding two byte value corresponding such as TAC add that a specific value can obtain corresponding LAC.
After receiving the current TAI that broadcasts the base station of evolution packet network as UE, can utilize above method, derive current LAI, judge whether identical with the LAI formerly that UE is stored whether this LAI, if different, then initiate the location area updating flow process, processing is upgraded in the position that is accomplished to the CS territory.The TAI that MME also can provide according to UE or eNodeB utilizes above method, derives corresponding LAI.
In this embodiment, its position updating process that is implemented to the CS territory is similar substantially with the flow process described in Fig. 9 to Fig. 7, and different is no longer to need to send to UE the TA List of LAI correspondence among this embodiment for MME among Fig. 7 and Fig. 9; In addition, UE also exists some to change when initiating position updating request, below the step that changes is described.
Please refer to Fig. 7 again, deriving by current TAI among the embodiment of current LAI, UE is by the assembling position lastest imformation, detect that current lane place changes or periodical location area upgrades timer expiry, then needing to carry out the position upgrades, in one embodiment, independent location area updating flow process is as follows:
S71, UE send the location area updating request message to MME, can comprise the LAI formerly of UE record or TAI (old TAI) formerly in this message.ENodeB can carry the residing TAI of current UE (current TAI) when transmitting this message to MME.
After S72, MME receive this location area updating request message, obtain the LAI formerly of UE and current LAI.For the LAI formerly of UE, MME can obtain according to following two kinds of methods:
1) if comprised the LAI formerly of UE storage in the location area updating request message, then directly uses this LAI;
2) if comprised TAI formerly in the location area updating request message, then MME can derive corresponding LAI formerly according to aforesaid derivation method.
For the current LAI of UE, then MME can be according to above-mentioned derivation method, and the current TAI that provides by eNodeB obtains corresponding current LAI.
Follow-up step is identical with the step of the step S73 of aforementioned introduction～S77, does not describe in detail at this.
Please refer to Fig. 9 again, deriving by current TAI among the embodiment of current LAI, UE detects that current lane place changes or periodical location area upgrades timer expiry, and associating TA/LA is new technological process more:
Step S91, UE send the tracing section updating request message to MME, can comprise the LAI formerly of UE or TAI formerly in this message.ENodeB can carry the residing TAI of current UE when transmitting this message to MME.
If this moment, UE also needed the initiating updating of tracking area flow process, then UE needs indication network initiating updating of tracking area and location area updating processing simultaneously; Otherwise the location area updating that only needs indication network to be initiated to the CS territory is handled.Can to be UE carry updating type sign cell at the tracing section updating request message to indicating mode, and the TA/LA that comprises associating is new logo or LA new logo more separately more.
Overtime when the periodical position renewing timer of UE, also can initiate this associated update flow process, type can be upgraded for period L A.
After step S93, MME receive this tracing section updating request message, obtain LAI formerly and the current LAI of UE.For the LAI formerly of UE, MME can obtain according to following two kinds of methods:
1) if comprised the LAI formerly of UE storage in the tracing section updating request message, then directly uses this LAI;
2) if comprised TAI in the tracing section updating request message, then MME can obtain corresponding LAI formerly according to above-mentioned derivation method.
For the current LAI of UE, then MME can be according to above-mentioned derivation method, and the present located TAI that provides by eNodeB obtains corresponding current LAI.
Other steps are identical with step S92, step S94～S98, do not describe in detail at this.
As the expansion of this embodiment, current Location Area Identification (LAI) can also directly be broadcasted except broadcasting the TAI in the base station of LTE; Send to the relevant signaling (as adhering to request, location area updating etc.) of MME for UE, except carrying present located TAI, can also carry present located LAI.In this case, UE can compare according to the current LAI that receives and the LAI formerly of preservation, whether the lane place change has taken place with decision, if both differences, represent that then the occurrence positions district changes, then need to initiate the position and upgrade, for example can be initiated to the location area updating flow process in CS territory by LTE/SAE.
Illustrated in the above embodiments, in evolution row packet network,, then be initiated to the process of the location area updating flow processing in CS territory when variation has taken place its lane place of UE perception.In some other embodiment of the present invention, also can not need UE to judge whether its lane place variation has taken place, only need its tracking area of monitoring whether variation has taken place, only need initiating updating of tracking area to handle, and judge by the Mobility Management Entity (MME) of evolution packet network whether the lane place of UE change has taken place, when Mobility Management Entity MME judges that change has taken place in the lane place, then replace UE to be accomplished to the location area updating processing in CS territory.Equally, also can replace UE to finish for periodic location area updating flow process by MME, it is the periodical position renewing timer that writes down and carry out UE among the MME, behind this timer expiry, tracking area according to the UE current record obtains residing lane place, and the periodical location area that replaces UE to be initiated to MME upgrades processing.
Seeing also shown in Figure 10ly, is that MME replaces UE to initiate a kind of schematic flow sheet that the position is upgraded among the present invention;
Step S101, when UE satisfies the trigger condition of tracing section updating flow process, UE sends the tracing section updating request message to MME.Can carry the LAI formerly of UE storage in this message.
Step S102, MME initiate to upgrade the position flow process to HLR/HSS, to HLR/HSS registration MME, and obtain the subscription data of user in evolution packet network.MME also can obtain the correspondence relationship information of LAI and TAI to HLR/HSS in this flow process.
Step S103, MME judge whether the lane place of UE changes, if change has taken place in the lane place, processing is upgraded in the position that then is initiated to the CS territory.Send the location area updating request message to MSC/VLR.
In concrete example, MME judges to be stored in the LAI formerly of the subscriber equipment among the MME in advance or whether the pairing TA tabulation of LAI formerly that UE carries comprises described current TAI information in S101, if judged result is a definite results, the present position-region of then judging described UE does not change, otherwise, the present position-region of then judging described UE changes, then needs to initiate the position and upgrades.
In other concrete example, also can, MME takes out LAC information from the TAC field of described current TAI information, or this TAC field is calculated LAC information according to pre-defined algorithm;
Generate the current LAI information of described UE according to described LAC information;
Formerly LAI can adopt the above-mentioned method of deriving current LAI from TAI to obtain, and the LAI formerly that also can use UE to carry in step S101 perhaps uses the LAI formerly among the former MME of pre-existing.
Judge described current LAI information and formerly whether LAI information is identical,, judge that then the present position-region of UE does not change if both are identical, otherwise, judge that then the present position-region of UE changes, then need to initiate the position and upgrade.
Step S104, MSC/VLR initiate to upgrade the position flow process to HLR/HSS, and MSC/VLR is registered to HLR/HSS, obtain the subscription data of user in the CS territory simultaneously.
Step S105, MSC/VLR send the position renewal to MME and accept message, can comprise in this message that MSC/VLR is TMSI and the LAI that UE distributes.
Step S106, MME send tracing section updating to UE and accept message, can comprise in this message that MME is the S-TMSI that UE distributes, and can comprise that also MSC/VLR is TMSI and the LAI that UE distributes.
To have distributed new S-TMSI or MSC/VLR be that UE has distributed new TMSI if step S107 MME is UE, and then UE sends tracing section updating to MME and finishes message.
Distributed new TMSI if step S108 MSC/VLR is UE, then MME sends the TMSI Reallocation Complete message to MSC/VLR.
Equally, the mapping table of LAI described in the embodiment of the invention and TA List can dispose in MME, also can be configured in the data center in the network, after MME starts, can initiatively obtain the mapping table of this LAI and TA List, or obtain the mapping table of this LAI and TA List by related procedure to this data center; When this mapping table changed, data center also can initiatively send to MME with new mapping table.For example, this data center can be HLR/HSS.The mapping table of LAI and TAList is configured among the HLR/HSS, MME can obtain the mapping table of LAI and TA List from HLR/HSS when upgrading the position flow process with HLR/HSS, or obtain the mapping table of LAI and TA List after MME starts to HLR/HSS by special signaling (as demand signalling).
Seeing also shown in Figure 11ly, is that MME replaces UE to initiate the another kind of schematic flow sheet that the position is upgraded among the present invention;
Step S111, when the trigger condition of UE tracing section updating flow process, UE sends the tracing section updating request message to MME.Can carry the LAI formerly of UE storage in this message.
Step S112, MME initiate to upgrade the position flow process to HLR/HSS, to HLR/HSS registration MME, and obtain the subscription data of user in evolution packet network.MME also can obtain the correspondence relationship information of LAI and TAI to HLR/HSS in this flow process.
Step S113, MME are according to the TAI and the present located TAI of UE record, and the corresponding relation of record LAI and TAI, whether the lane place of judging UE changes, if change has taken place in the lane place, processing is upgraded in the position that then needs to be initiated to the CS territory, sends the location area updating request message to MSC/VLR.Wherein, judge whether the lane place method that changes has taken place can no longer give unnecessary details at this with reference to the explanation to the step S103 of Figure 10.
Step S114, MSC/VLR initiate to upgrade the position flow process to HLR/HSS, and MSC/VLR is registered to HLR/HSS, obtain the subscription data of user in the CS territory simultaneously.
Step S115, MSC/VLR send the position renewal to MME and accept message, can comprise in this message that MSC/VLR is TMSI and the LAI that UE distributes.
Step S116, MME send tracing section updating to UE and accept message, can comprise in this message that MME is the S-TMSI that UE distributes.
Distributed new S-TMSI if step S117 MME is UE, then UE sends tracing section updating to MME and finishes message.
Step S118, MME send location area updating to UE and accept message, can comprise in this message that MSC/VLR is TMSI and the LAI that UE distributes.
Distributed new TMSI if step S119 MSC/VLR is UE, then UE sends the heavy assignment messages of TMSI to MME.
Step S1110, MME transmit the TMSI Reallocation Complete message to MSC/VLR.
Wherein, the order of step S116～S117 and step S118～S1110 does not have precedence relationship.
Seeing also shown in Figure 12ly, is that MME replaces UE to initiate a kind of schematic flow sheet that periodic position is upgraded among the present invention;
