Description
Technical field
The present invention relates to the mobile communication technology field, relate in particular to a kind of position method for updating, network equipment, a kind of request position method for updating, subscriber equipment, and a kind of method and network side access device that inserts for subscriber equipment.
Background technology
At present, GSM (Global System for Mobile communications, global system for mobile communications) and WCDMA (Wideband Code Division Multiple Access, Wideband Code Division Multiple Access (WCDMA)) 2G/3G (2rd Generation/3rd Generation such as, second generation mobile communication technology/3G (Third Generation) Moblie technology) network is through for many years deployment, can be regarded as a kind of network of comprehensive covering to a certain extent, and SAE (SAE:System Architecture Evolution, System Architecture Evolution), LTE (LongTerm Evolution, Long Term Evolution), HSPA (High-Speed Packet Access, high-speed packet inserts), HSPA+ and WiMAX (Worldwide Interoperability for Microwave Access, general inserting of microwave globalizes) etc. pure PS territory network only cover part city and traffic hot zones, therefore cause the subregion simultaneously by the 2G/3G network and the pure PS territory network coverage, and the subregion is only by the 2G/3G network coverage.
Based on above-mentioned network coverage present situation, UE (subscriber equipment, User Equipment) might cross over two kinds of different networks in the call process.Heterogeneous networks has different carrying mechanisms, and for example, for pure PS territory network, speech business can only be carried on PS (Packet Switching) territory to be transmitted; And for the 2G/3G network, speech business generally all is to be carried on CS (CS, the Circuit Switched) territory to transmit.And then, if UE only from being shifted out, enter by the zone of the pure PS territory network coverage by the 2G/3G network cover separately regional the time, speech business need be switched to the CS territory from the PS territory, therefore just the interruption of speech business might occur, thereby influence the continuity of user speech business.
For the situation of avoiding above-mentioned speech business to be interrupted occurs as far as possible, present a solution is that all speech businesses are all carried out in the CS territory of 2G/3G network.Be that example describes the existing technical scheme that solves the speech business discontinuous problem in detail with 2G/3G network and LTE network below, in this area, LA (LocationArea, lane place) sub-district refers to the sub-district in the 2G/3G network, TA (Tracking Area, tracking area) sub-district refers to the sub-district in the LTE network.Particularly, the MSC of 2G/3G network (Mobile SwitchingCenter, mobile switching centre) receive the voice paging message that calling UE sends after, issue this voice paging message to the LA sub-district that this calling UE is registered, simultaneously also to this voice paging message of LTE forwarded, and then the MME in the LTE network (Mobility Management Entity, mobile management entity) issues voice paging message to the TA sub-district that called UE is registered.After called UE in quartering at the LTE network (promptly having registered and be linked into the UE of LTE network) receives this voice paging message, called UE is linked into the CS territory of 2G/3G network immediately again, and then calling and called UE is follow-up can carry out the audio call process in the CS territory in the 2G/3G network.This shows that technique scheme is all carried out all speech businesses in the CS territory of 2G/3G network, therefore can not occur because UE moves the situation appearance that causes speech business to be interrupted.
Adopt technique scheme, when requiring UE to be linked into 2G/3G CS territory, LAI (the Location Area Identifier of the LA sub-district that UE inserts, Location Area Identification) LAI with user's registration will try one's best consistent, need carry out the LA renewal process to reduce when the user is linked into the 2G/3G network, avoid causing the time-delay of call setup.Consistent as far as possible with the LAI of user's registration for the LAI that guarantees UE access sub-district, the technical scheme that adopts is in time to carry out the co-location renewal of TA/LA at present.The co-location of so-called TA/LA is upgraded and is specifically comprised: in the zone that LTE network and 2G/3G network cover simultaneously, when UE is registered in the LTE network, also register at the 2G/3G network simultaneously; When UE finds that TA or LA change in moving process, need carry out the renewal of TA and LA.
In order to reach the purpose that the TA/LA co-location is upgraded, need dispose mapping between TA and the LA in cell-level, specifically please referring to Fig. 1, it is existing a kind of TA and LA mapping relations schematic diagram.In Fig. 1, comprise a plurality of TA sub-district in the zone of TA1 representative, wherein the TAI of each TA sub-district is TA1.Comprise a plurality of LA sub-district in the zone of LA1 representative, wherein the LAI of each LA sub-district is LA1; In like manner, the LAI of each the LA sub-district in the zone of LA2 representative is LA2; The LAI of each the LA sub-district in the zone of LA3 representative is LA3.System is corresponding with it for each TA sub-district all disposes a unique LAI.The zone (for example overlapping dash area of LA1 and LA3 among Fig. 1) that covers simultaneously as for a plurality of LA, system can be corresponding with it for the LAI of a TA cell configuration that is in this zone in according to certain principle (such as optimization principles), and is corresponding with TA1 or to dispose LA3 corresponding with TA1 such as configuration LA1.
The configuration of the corresponding relation eNodeB of each in LTE (Envolved NodeB normally between above-mentioned TA sub-district and the LAI, the Node B of evolution) finishes, when the UE of enodeb in quartering at the LTE network issues broadcast or dedicated signaling, carry this enodeb and administer the TAI of TA sub-district and the LAI of this TA sub-district correspondence.UE registers in PS territory and CS territory respectively according to the TAI and the LAI that receive.If UE is in mobile status, along with the variation of UE sub-district of living in, the broadcast that receives of UE or the TAI in the dedicated signaling and LAI just might change so.And then the LAI that finds the broadcast receive or the LAI in the dedicated signaling and own registration as UE will send the TA/LA update request to eNodeB, not simultaneously so network side can TA upgrades and the LA renewal for this user carry out.
Particularly, eNodeB is transmitted to MME with this update request after receiving the TA/LA update request of UE, and on the one hand, MME will take certain resource and finish this UE in the TA in PS territory renewal; On the other hand, MME informs MSC by the registration passage between itself and the MSC with new LAI, and then MSC also will take certain resource and finishes the LA of this UE in the CS territory and upgrade.The inventor finds in realizing process of the present invention, and whenever UE receives LAI that network side issues when changing, the CS territory of network side and PS territory all will be carried out the position respectively and upgraded, and have therefore taken a large amount of network side resources.
In addition, the front to be mentioned in order avoid as far as possible and to be interrupted owing to UE moves the speech business that causes, and all speech businesses all will be carried out in the CS territory of 2G/3G network.If the sub-district gravity treatment took place in the called subscriber before being linked into the CS territory, and when the residing zone of IE is covered (for example overlapping dash area of LA1 and LA3 among Fig. 1) simultaneously by the sub-district of Different L AI, network side is that the LAI of the new LA sub-district of selecting of UE might not be the LAI of this UE registration according to the optimization principles of sub-district gravity treatment, therefore also need to take certain resource and carry out the LA renewal, also caused the time-delay of call setup to a certain extent.

Embodiment
See also Fig. 2, it is for the first embodiment flow chart of location updating method of the present invention.
Step 210: receive the location update request message that UE reports, this location update request message comprises the indication information that only carries out the LAI renewal and do not carry out the TAI renewal.
In background technology, carried, be in the message (as broadcast or dedicated signaling) that the UE of mobile status issues according to network side, can know the TAI of the current TA of living in of UE sub-district and the LAI of the current TA of living in of UE sub-district correspondence.
For example, the eNodeB of LTE network side issues broadcast or dedicated signaling to the UE that quarters at wherein, comprises the TAI (as TA1) of TA sub-district of this eNodeB administration and the LAI (as LA1) of this TA sub-district correspondence in described broadcast or the dedicated signaling.Corresponding relation between LA1 and this TA sub-district is pre-configured on the eNodeB, when the eNodeB of this TA sub-district of administration issues broadcast or dedicated signaling, just can carry the TA1 and the corresponding LA1 of this TA sub-district therein, if UE this moment quarters at the TA sub-district of this eNodeB administration, just can receive broadcast or dedicated signaling that eNodeB issues, and then the TAI of knowing current TA of living in sub-district is TA1, and corresponding LAI is LA1.
In addition, in UE, preserve oneself registration TAI and registration LAI (being that UE carries out CS territory, registration back, PS territory, is kept at TAI and LAI in the log-on message) information, therefore, UE can judge whether the TAI of current TA of living in sub-district is consistent with the registration TAI of oneself, and whether the LAI of current TA of living in sub-district correspondence is consistent with the registration LAI of oneself.If the result who judges is the TAI unanimity, and LAI is inconsistent, will send location update request message to eNodeB so, and in this location update request message, comprise the indication information that only carries out the LAI renewal and do not carry out the TAI renewal.
The registration TAI that supposes UE is TA1, and registration LAI is LA2, and the TAI of the current TA of living in of the UE that UE receives sub-district is TA1, and the LAI of the current TA of living in of UE sub-district correspondence is LA1, and then UE just can judge that TAI does not change, and is that variation has taken place LAI.So UE sends location update request message to eNodeB, the log-on message of LAI is upgraded in request.
From the angle of network side, eNodeB can receive the location update request message that UE reports, and wherein comprises the indication information that only carries out the LAI renewal and do not carry out the TAI renewal.UE has shown that to network side the TAI of the current TA of living in of UE sub-district is identical with the registration TAI of UE by this indication information, and the LAI of the current TA of living in of UE sub-district correspondence is different with the registration LAI of UE.Generally speaking, except comprising above-mentioned indication information, also comprise registration LAI (being old TAI), the TAI of the current TA of living in of UE sub-district of LAI (being new LAI), UE of the current TA of living in of UE sub-district correspondence and the registration TAI of UE in the location update request message.Because the TAI of the current TA of living in of UE sub-district is identical with the registration TAI of UE, therefore, also can not carry the information of TAI in the location update request message.ENodeB receives and is transmitted to MME after the location update request message of UE and handles.
Step 220: according to described location update request message is that described UE carries out the renewal of LAI and do not carry out the renewal of TAI.
The indication information of MME from location update request message, know the TAI and registration TAI identical (being that TAI does not change) of the current TA of living in of UE sub-district, and the LAI of the current TA of living in of UE sub-district correspondence and registration LAI different (being that variation has taken place LAI), so by (the Mobile Switching Center of the MSC in MME and the 2G/3G network, mobile switching centre) the registration passage between sends to MSC with the LAI (LA1) of the current TA of living in of UE sub-district correspondence, and then finishes the renewal (the registration LAI that be about to UE by LA2 upgrade LA1) of UE at the LAI in 2G/3G network C S territory by MSC.Because MME knows the TAI of UE and do not change, so MME does not take resource and carries out UE and upgrade at the TAI of LTE network PS field.Even TAI does not change in the prior art relatively, also need the TAI that carries out the PS territory to upgrade, first embodiment of the invention has been saved a large amount of TAI of network side and has been upgraded signal resource.
See also Fig. 3, it is for the second embodiment flow chart of location updating method of the present invention.Present embodiment and the difference part of aforementioned first embodiment are that the particular content of the location update request message that receives is different.
Step 310: receive the location update request message that UE reports, include only the information of LAI in this location update request message and do not comprise the information of TAI.
The message that UE issues according to network side can know that the TAI of own current TA of living in sub-district is TA1, corresponding LAI is LA1, and the registration TAI and the registration LAI that preserve oneself among the UE (suppose that registration TAI is TA1, registration LAI is LA2), and then, UE just can judge that the TAI of current TA of living in sub-district is consistent with the registration TAI of oneself, and the LAI of current TA of living in sub-district correspondence is inconsistent with the registration LAI of oneself.So, UE sends location update request message to eNodeB, in order to show to network side only is that LAI has taken place to change and TAI does not change, can in this location update request message, only comprise the information (LA1) of LAI and do not comprise the information (network side can identify this implication) of TAI, in other words, by in location update request message, not carrying the implicit mode of TAI information, show that to network side TAI does not change.
Step 320: according to described location update request message is that described UE carries out the renewal of LAI and do not carry out the renewal of TAI.
MME does not comprise TAI information according to only comprising LAI information in the location update request message, can know that TAI does not change, and only need carry out the renewal of LAI.Concrete update mode is identical with step 220 among first embodiment, so repeat no more.In like manner, do not change, therefore do not take resource and carry out UE in the TAI of LTE network PS field renewal because MME knows the TAI of UE.Even TAI does not change in the prior art relatively, also need the TAI that carries out the PS territory to upgrade, second embodiment of the invention has been saved a large amount of TAI of network side equally and has been upgraded signal resource.
See also Fig. 4, it realizes the example structure schematic diagram of the network equipment that the position is upgraded for the present invention.Network equipment in the present embodiment comprises update request receiving element 421 and upgrades processing unit 422, introduces its internal structure and annexation in detail below in conjunction with the operation principle of this equipment.
Wherein, update request receiving element 421 is used to receive the location update request message that UE reports, described location update request message shows that the TAI of the current TA of living in of UE sub-district is identical with the registration TAI of UE, and the LAI of the current TA of living in of described UE sub-district correspondence is different with the registration LAI of UE.For example, the TAI of the current TA of living in of UE sub-district is TA1, and the LAI of the current TA of living in of UE sub-district is LA1, and the registration TAI of UE is TA1, and registration LAI is LA2.
Location update request message shows that the TAI of the current TA of living in of UE sub-district is identical with the registration TAI of UE, the LAI of the current TA of living in of UE sub-district correspondence is different with the registration LAI of UE can multiple specific implementation, for example comprises the indication information that only carries out the LAI renewal and do not carry out the TAI renewal in location update request message; The implicit mode that does not perhaps comprise TAI information by the information that includes only LAI in location update request message shows that to network side TAI does not change just LAI change.
The network equipment embodiment of the embodiment of location updating method and the renewal of realization position as can be seen in sum, if the TAI of the current TA of living in of described UE sub-district is identical with the registration TAI of UE, and the LAI of the current TA of living in of UE sub-district correspondence is different with the registration LAI of UE, then the renewal of TAI is not carried out in the renewal of only carrying out LAI for described UE, and therefore prior art has been saved a large amount of signal resource of network side relatively.
See also Fig. 5, it is a kind of request of the present invention position method for updating first embodiment flow chart.Described flow process comprises:
Step 510: receive the current TA of living in of the UE sub-district that network side issues TAI (as TA1) and as described in the LAI (as LA1) of the current TA of living in of UE sub-district correspondence.
Step 520: if the TAI of the current TA of living in of UE sub-district is identical with the registration TAI of described UE, and the LAI of the current TA of living in of UE sub-district correspondence is different with the registration LAI of described UE, then send location update request message to network side, described location update request message shows that the TAI of the current TA of living in of described UE sub-district is identical with the registration TAI of described UE, and the LAI of the current TA of living in of described UE sub-district correspondence is different with the registration LAI of described UE.
Particularly, suppose that the registration TAI of UE is TA1, registration LAI is LA2, and the TAI of the TA current of living in sub-district that UE receives is TA1, and the LAI of current TA of living in sub-district correspondence is LA1, and so, UE just can judge that TAI does not change, and variation has taken place LAI.So, sending location update request message to network side, described location update request message shows that the TAI of the current TA of living in of described UE sub-district is identical with the registration TAI of described UE, and the LAI of the current TA of living in of described UE sub-district correspondence is different with the registration LAI of described UE.The mode that shows of location update request message has multiple implementation, for example comprises the indication information that only carries out the LAI renewal and do not carry out the TAI renewal in location update request message; The implicit mode that does not perhaps comprise TAI information by the information that includes only LAI in location update request message shows that to network side it is that LAI has changed that TAI does not change.
See also Fig. 6, it realizes the structural representation of the subscriber equipment embodiment of position updating request for the present invention.Subscriber equipment in the present embodiment comprises receiving element 610 and update request transmitting element 620, introduces its internal structure and annexation in detail below in conjunction with the operation principle of this subscriber equipment.
Receive the TAI of the current TA of living in of the UE sub-district that network sides issue and the LAI of the current TA of living in of UE sub-district correspondence by receiving element 610.Because UE self preserves registration LAI and registration TAI information, therefore, when the TAI of the current TA of living in of UE sub-district identical with the registration TAI of UE, and the registration LAI of the LAI of the current TA of living in of UE sub-district correspondence and described UE is not simultaneously, send location update request message by the update request transmitting element to network side, described location update request message shows that the TAI of the current TA of living in of UE sub-district is identical with the registration TAI of described UE, and the LAI of the current TA of living in of described UE sub-district correspondence is different with the registration LAI of described UE.
The mode that shows of location update request message has multiple specific implementation, for example comprises the indication information that only carries out the LAI renewal and do not carry out the TAI renewal in location update request message; The implicit mode that does not perhaps comprise TAI information by the information that includes only LAI in location update request message shows that to network side it is that LAI has changed that TAI does not change.
By above-mentioned request position method for updating embodiment and subscriber equipment embodiment as can be seen, if the TAI of the current TA of living in of UE sub-district is identical with the registration TAI of UE, and the LAI of the current TA of living in of UE sub-district correspondence is different with the registration LAI of UE, then subscriber equipment can show that when network side sends position updating request TAI does not change just LAI variation, and then the renewal that network side just can be in view of the above only carries out LAI for UE do not carry out the renewal of TAI, and therefore prior art can be saved a large amount of signal resource of network side relatively.
See also Fig. 7, the method embodiment flow chart that it inserts for subscriber equipment for the present invention.Described flow process comprises:
Step 710: receive the access request of UE.
For example, occur for fear of move the interruption situation that causes speech business owing to UE, carry out in the CS territory that all speech businesses can be based upon in the 2G/3G network.Therefore, after the called UE in quartering at the LTE network (promptly having registered and be linked into the UE of LTE network) received this voice paging message, in the time of need being linked into the CS territory of 2G/3G network again, i.e. transmission to network side inserted request.
Step 720: for described UE carries out the sub-district gravity treatment, the preferential LA sub-district of selecting to be designated described UE registration LAI in satisfying the LA sub-district object of sub-district reselection conditions.
Because network side need be linked into the UE that was linked into the LTE network PS field originally the CS territory of 2G/3G network, therefore the sub-district gravity treatment can take place, be this UE and select a LA sub-district to provide the access service in CS territory for it.Please in conjunction with referring to Fig. 1, if the sub-district gravity treatment takes place, UE has moved to that on behalf of zone and LA3, LA1 represent the dash area of region overlapping among the figure, promptly in the adjacent cell list of UE, include a plurality of LA sub-districts that belong to Different L AI, so, select which LA sub-district to provide the problem of access service for it with regard to existing for this UE.Upgrade the preferential identical sub-district of LAI of selecting LAI and LTE sub-district to be disposed in satisfying the LA sub-district object of sub-district reselection conditions in order to avoid that as far as possible LA takes place.
Particularly, select at least two LA sub-district objects that satisfy the sub-district reselection conditions according to predetermined sub-district reselection conditions.For example, described predetermined sub-district reselection conditions is a demand on signal quality, the optional object in LA sub-district that satisfies this demand on signal quality in adjacent cell list is respectively Cell (sub-district) 1, Cell 2, Cell 3 and Cell 4, wherein, the LAI of Cell 1 is LA1, the LAI of Cell 2 is LA1, and the LAI of Cell 3 is LA3, and the LAI of Cell 4 is LA3.The registration LAI that supposes UE is LA1, and so just selecting LAI in above-mentioned four optional objects is that the LA sub-district of LA1 provides access service for this UE, and then does not need to have carried out the renewal of LAI again.With regard to the foregoing description,, therefore can therefrom select one to provide access service according to certain principle (as the signal optimizing principle) for UE because the LAI of Cell 1 and Cell 2 all is LA1.
See also Fig. 8, it is for the access device example structure schematic diagram of network side of the present invention.Access device in the present embodiment comprises receiving element 810, gravity treatment unit 820, sub-district and access unit 830.Operation principle below in conjunction with this access device is introduced its internal structure and annexation in detail.
At first, receive the access request of UE by receiving element 810.For example, the UE request inserts the access request in the CS territory of 2G/3G network.Then, carry out the sub-district gravity treatment for described UE, the preferential LA sub-district of selecting to be designated this UE registration LAI in satisfying the LA sub-district object of sub-district reselection conditions by gravity treatment unit, sub-district 820.Particularly, gravity treatment unit, sub-district 820 comprises initial option unit 821 and final selected cell 822, and wherein, initial option unit 821 is used for selecting at least two LA sub-district objects that satisfy the sub-district reselection conditions according to predetermined sub-district reselection conditions; Final selected cell 822 is used for comprising under the LA cell conditions that is designated described UE registration LAI at the described LA sub-district object that satisfies the sub-district reselection conditions, selects the described LA sub-district that is designated UE registration LAI.
And then access unit 830 adopts 820 selected LA sub-districts, gravity treatment unit, sub-district to provide access service for this UE.
From the above-mentioned method embodiment that inserts for subscriber equipment and access device embodiment as can be seen, when the sub-district gravity treatment takes place, and when having a plurality of LA sub-district object that satisfies the predetermined cell reselection conditions again, the preferential LA sub-district of therefrom selecting to be designated UE registration LAI provides service for UE, thereby reduced the possibility that LA upgrades to a certain extent, and then avoided the time-delay of call setup to a certain extent.
