Description
Technical field
The present invention relates to the ICQ technical field, relate in particular to paging method, Apparatus and system under the common coverage condition of a kind of many networks.
Background technology
Along with the development of the network communications technology, the various communication networks that lay particular emphasis on different services arise at the historic moment, and can not stagger fully in the overlay area of these communication networks, have overlapped part.From the another one angle, be that some zone may be covered simultaneously by polytype network, for example, the overlay area of public network may comprise the overlay area of limited network fully, perhaps overlap with the overlay area of limited network, limited network can be a private network, and the access control node of limited network can be family expenses AP (ACCESSPOINT, access point) or family expenses enodeB (enhancement mode Node B) etc.
See also Fig. 1, there is a kind of situation schematic diagram of lap in its overlay area for two kinds of communication networks in the prior art.Elliptic region maximum among the figure is sub-district 1, and it is in the overlay area of public network; Less elliptic region is sub-district 2, and it not only had been in the overlay area of public network but also had been in the overlay area of limited network, and in other words, sub-district 2 is covered simultaneously by public network and limited network.
To different communication networks, generally can distribute different lane place TA (TrackArea, track zone), such as, the lane place of distributing to sub-district 1 is TA1, the lane place of distributing to sub-district 2 is TA2.Usually, each sub-district all can issue the TA of oneself, and then UE (subscriber equipment) adopts substitute mode to preserve the TA that it receives by the TA table.For example, when UE enters into sub-district 1 with regional beyond interior, the sub-district 2, can receive the TA1 that sub-district 1 issues, and be kept at during own TA shows; When moving to sub-district 2, UE when regional, can receive the TA2 that sub-district 2 issues again, so UE just uses the TA2 that newly receives and replaces the TA1 that preserves in the former TA table with interior; When UE again beyond the mobile cell 2, when regional, it receives the TA1 that sub-district 1 issues again, and then replaces TA2 with TA1 again with interior in sub-district 1.
This shows, if UE frequently sub-district 2 with interior zone and sub-district 2 beyond, sub-district 1 moves between with interior zone, be that the border of UE between public network and limited network is when moving around, UE can frequently revise the TA table information of oneself, and UE will report to CN (core net) by eating dishes without rice or wine when the TA information of preservation takes place to upgrade at every turn, so that make CN can know the UE location area information, this phenomenon is called as TAU (Tracking Area Update, track region area update).Because the existence of TAU makes UE frequently report the lastest imformation of TA to CN, and then causes Internet resources to be taken in a large number, adopt two kinds of solutions that reduce TAU at present.
Scheme one does not adopt substitute mode to carry out the TA information stores in the TA table that UE preserves, but stores a plurality of simultaneously.For example, when the border of UE between public network and limited network moves around, its a plurality of TA information that receive (TA2 that TA1 that issues as sub-district 1 and sub-district 2 issue) all are kept in the TA table of oneself, and then, when the border of UE between these two networks moves around, the TA information that UE preserves all comprises TA1 and TA2 all the time, does not upgrade.Therefore UE also just need not to report the TA lastest imformation to network side, has promptly reduced the generation of TAU.But, because UE preserves and the zone of location area information (TA1+TA2) representative that reports is wider---not only represented sub-district 1 that public network covers but also the sub-district 2 of representing limited network to cover, therefore, network side both can paging in the sub-district 1 (TA1) that public network covers when the UE position district information of knowing according to it is carried out paging, also can paging in the sub-district 2 (TA2) of limited network covering.
Scheme two, for distributing identical TA3 with sub-district 2 in sub-district 1, the lane place of TA3 representative not only comprises the sub-district 1 that public network covers but also comprise the sub-district 2 that limited network covers, and then, when the border of UE between public network and limited network moves around, the concrete TA information that UE is kept in the own TA table can't change, and all is TA3 all the time, so just TAU can not take place.With last scheme in like manner, because UE preserves and the zone of the location area information TA3 representative that reports is wider---not only represented sub-district 1 that public network covers but also the sub-district 2 of representing limited network to cover, therefore, network side both can paging in the sub-district 1 (TA1) that public network covers when the UE position district information of knowing according to it is carried out paging, also can paging in the sub-district 2 (TA2) of limited network covering.
The inventor of present patent application finds above-mentioned these two kinds of solutions at work, though can avoid the TAU phenomenon, but, network side is when carrying out paging to UE, all must paging in the Zone Full of location area information (as the TA3 in TA1+TA2 in the scheme 1 or the scheme 2) representative that UE reports (being the sub-district 2 that the sub-district 1 that covers of public network and limited network cover), so the paging load of network side is very big.

Embodiment
Below in conjunction with accompanying drawing a plurality of specific embodiments of the present invention are elaborated.
Among the paging method embodiment under the common coverage condition of the many networks of the present invention, network side preservation has the UE location area information of knowing in advance that is allowed to access limited network and public network, and the zone of described location area information representative comprises the zone of first network (as the limited network) covering with overlapping region and the zone that second network (as public network) covers at least; Then, network side by multiple specific implementation (as UE come in and go out the up-to-date UE location area information of the current discrepancy information of first network or network side record or both in conjunction with) determine as described in the concrete network of UE present located; At last, network side is determined result described UE of priority paging in described location area information is represented subregion in the zone based on this, priority paging may be the zone of first network coverage, also may be the zone of second network coverage.Need to prove, in embodiments of the present invention, the concrete execution entity of described network side is understood differences to some extent according to the specific implementation difference, for example, it may be the first network insertion Control Node, also may be CN, also may be described both combinations, can introduce respectively in conjunction with a plurality of specific embodiments hereinafter.
In addition, need to prove, following each embodiment of the present invention has on the UE location area information basis of knowing in advance that is allowed to access limited network and public network in network side preservation, the improvement of carrying out at prior art, described location area information can adopt the solution one of the existing minimizing TAU that mentions in the background technology or the relevant concrete technology in the solution two to be achieved, so that reach the purpose that reduces TAU, for example to report the location area information at own place can be (TA1+TA2) to UE, the sub-district 2 that on behalf of sub-district 1 that limited network covers and public network, it cover; Also can be TA3, sub-district 1 and public network coverage cell 2 that on behalf of limited network, TA3 in fact also cover.Therefore, repeat no more concrete disclosing in a plurality of paging embodiment idiographic flow of the present invention.Described network side preservation has the UE location area information of knowing in advance that is allowed to access limited network and public network mainly to comprise two layers of meaning:
One, adopt the UE of embodiment of the invention technical scheme to be allowed to access limited network and public network, because if this UE is not allowed to access this two networks, with regard to not relating to frequent TAU and causing the problem of network resources waste, just there is no need the technical scheme that adopts the embodiment of the invention to provide naturally.How to determine UE as for network side and whether be allowed to access these two networks multiple implementation can be arranged, for example according to the CAMEL-Subscription-Information of UE or the attribute of UE, or the location area information that reports of UE etc.
Its two, network side preservation has the UE location area information of knowing in advance, on behalf of the zone, described location area information comprise limited network overlay area and public network overlay area at least, the zone of these two network coverages has the overlapping region.
No longer above-mentioned steps is given unnecessary details in follow-up specific embodiment, the default network side has been known the positional information at the UE place that is allowed to access limited network and public network, only highlights the paging processing procedure after network side is known the UE lane place.
See also Fig. 2, it is that the many networks of the present invention are total to the paging method first embodiment schematic flow sheet under the coverage condition.Limited network in the present embodiment is corresponding to first network, and public network is corresponding to second network.UE has represented the zone of public network covering and the zone that limited network covers to the location area information that network side reports.
Step 210: limited network is known the discrepancy information of UE discrepancy limited network.The specific implementation of this step has multiple, for example, when entering limited network, UE can send a piece of news to limited network, this message can be cell update (cell update) or RRC (Radio Resource Control, Radio Resource control) connect and set up message etc., and UE can be that idle condition also can be a connection status when sending this message.Generally speaking, as long as UE can both tell that limited network access control node is just passable when it enters limited network and leaves limited network at every turn, promptly report the current discrepancy information of the limited network of oneself coming in and going out.Limited network access control node can be preserved UE by multiple modes such as record sheets and have a situation in this limited network.
Step 220:CN changes step 230 over to then to the beep-page message of this UE of limited network access control node distributing paging.In the basic step of preamble, mention as each embodiment, the UE that mentions in the embodiment of the invention not only is allowed to access limited network but also be allowed to access public network, in other words, network side has been determined this UE according to the CAMEL-Subscription-Information of UE, the attribute of UE or the location area information that UE reports etc. and has been allowed to access this two networks.Consider generally, for UE, more favourable based on the limited network access based on the public network access, so CN pays the utmost attention to paging in the limited network for the UE that allows the access limited network, promptly preferential beep-page message to this UE of limited network access control node distributing paging.
Step 230: limited network access control node determines that based on the current discrepancy information of the UE of knowing in the step 210 this UE is current whether in the Home Network coverage.If change step 240 over to; If not, change step 250 over to.
Step 240: limited network access control node is the beep-page message by (claiming the Radio Resource interface again) this UE of distributing paging that eats dishes without rice or wine directly.In other words, CN is by limited network access control node this UE of paging in the UE location area information that it is known is represented limited network overlay area in the zone, if corresponding to concrete condition shown in Figure 1, be this UE of paging in the sub-district 2 that limited network covers.
Step 250: limited network access control node by the beep-page message of this UE of distributing paging that eats dishes without rice or wine, does not change step 260 over to then to the failure of CN answer page.
Step 260:CN is by public network access control node this UE of paging in the UE location area information that it is known is represented public network overlay area (corresponding to the sub-district among Fig. 1 1) in the zone.Need to prove, in order to make CN easier when specific implementation is operated, this step also can change to: CN is this UE of paging in described UE location area information is represented regional Zone Full, and described Zone Full comprises the zone of public network covering and the zone that limited network covers at least.
By the process shown in the above-mentioned steps 210 to 260 as can be seen, though on behalf of the zone, the location area information that UE reports to network side comprised the zone of public network covering and the zone that limited network covers, but, as long as network side is determined its current limited network that is in based on the current discrepancy information of UE, just preferentially paging in the zone that limited network covers of network side so; Have only when determining its current limited network that left based on the current discrepancy information of UE, perhaps under the network side situation that preferentially this UE of paging fails in the zone that limited network covers, network side just need carry out paging in the zone that public network covers, therefore, need for paging in the UE location area information is represented regional Zone Full (zone that zone that public network covers and limited network cover), significantly reduce paging load with respect to the existing network side.
Whether in addition, what need supplementary notes is, limited network access control node also can report CN again after receiving the current discrepancy information that UE reports, and then determine in view of the above by CN that UE is current and be in the limited network, and then decides the scope of paging again.For example, if CN determines that based on the current discrepancy information of UE UE is current in limited network, CN just preferentially sends beep-page message to the limited network Control Node so, and then by limited network Control Node this UE of paging in the limited network scope; If CN determines that based on the current discrepancy information of UE UE is current not in limited network, CN just preferentially sends beep-page message to the public network Control Node so, and then by public network Control Node this UE of paging in the public network scope.Generally speaking, can know the current discrepancy information of UE as long as guarantee network side, determine in view of the above then just can to guarantee preferentially in its location area information is represented subregion in the zone, to carry out paging, as for network side is which concrete entity to finish not restriction by, it for example can be limited network access control node, also can be CN, or both combinations, even all right other service-specific entities etc.
See also Fig. 3, it is that the many networks of the present invention are total to the paging method second embodiment schematic flow sheet under the coverage condition.The main distinction part of present embodiment and first embodiment shown in Figure 2 is: though UE not only is allowed to access limited network but also be allowed to access public network, but the CN in the present embodiment is simultaneously to limited network Control Node and public network Control Node issuing page message, if determine according to current discrepancy information under the current not situation in limited network of UE in the limited network Control Node, limited network does not just send beep-page message to eating dishes without rice or wine so, and then has saved interface-free resources and paging load.Request in person the detailed process of seeing present embodiment down, repeat no more for the step identical with first embodiment.
Step 310: limited network is known the current discrepancy information of UE discrepancy limited network.
Step 320:CN is the limited network access control node in the UE position district information of knowing is represented limited network overlay area in the zone and the public network access control node issuing page message in the public network overlay area respectively, changes step 330 and step 360 then respectively over to.
Step 330: limited network access control node determines that based on the current discrepancy information of the UE of knowing in the step 310 this UE is current whether in the Home Network coverage.If change step 340 over to; If not, change step 350 over to.
Step 340: limited network access control node is the beep-page message by this UE of distributing paging that eats dishes without rice or wine directly.
Step 350: limited network access control node abandons this beep-page message that it receives from CN not by the beep-page message of this UE of distributing paging that eats dishes without rice or wine.
Step 360:CN is by public network access control node this UE of paging in the UE location area information that it is known is represented public network coverage in the zone.
By above-mentioned steps 310 to 360 as can be seen, though determine based on the current discrepancy information of UE of record that at limited network access control node it is currently located under the situation in the limited network, network side can all carry out paging in the UE location area information that it is known is represented limited network overlay area in the zone and public network overlay area; But, if limited network access control node is determined under its current situation of having left limited network based on the current discrepancy information of UE of record, the limited network Control Node is just by sending beep-page message to eating dishes without rice or wine, and then saved interface-free resources and paging load.
See also Fig. 4, it is that the many networks of the present invention are total to paging method the 3rd embodiment schematic flow sheet under the coverage condition.The main distinction part of present embodiment and first, second embodiment is: whether comprise special identifier in the up-to-date UE location area information that present embodiment is mainly known according to CN, determine in the current coverage that whether is in limited network of UE.
A kind of concrete condition that present embodiment is suitable for is: network side is that same position district (as TA3) is distributed in the sub-district 2 of limited network covering and the sub-district 1 of public network covering, and then the border of UE between limited network and public network is when moving around, the TA information (TA3) of its preservation is constant, and then the TAU phenomenon can not take place; In addition, network side also increases a special identifier for limited network.UE reports the location area information at own place to mainly contain two kinds of situations, first location area information reports when upgrading, it two is periodic reports, if UE enters periodic report at a time when the limited network, so, though its TA remains TA3, this moment can thereafter additional one show the special identifier that lays oneself open in the limited network, this special identifier is that network side is the mark that limited network distributes, and described special marking can be informed UE by system broadcast message or other message.And then, the location area information of the UE periodic report that CN receives has two kinds of situations, the first comprises lane place data TA3, it two is to comprise lane place data TA3 and special identifier, the former is in outside the limited network when UE periodic report location area information is described, the latter is in the limited network when UE periodic report location area information is described.Whether CN generally can write down and upgrade after receiving the location area information that UE reports, and therefore, whether CN just can according to comprising above-mentioned special identifier in the last location area information of the UE of its record, determine that UE is current to be in the limited network.Request in person the detailed process of seeing present embodiment down:
Whether comprise special identifier in the up-to-date UE location area information of step 410:CN according to its preservation and determine that UE is current whether in limited network.If CN determines that UE is current and is in the limited network, then change step 420 over to; Otherwise, change step 430 over to.
Step 420:CN is by limited network access control node this UE of paging in limited network.If this step paging failure changes step 430 again over to; If the paging success does not just need this UE of paging in the public network zone more naturally, thereby reached the purpose that reduces paging load.
Step 430:CN is by public network access control node this UE of paging in public network.Certainly, for specific implementation is easy, this step also can be: CN is this UE of paging in the UE location area information that it is known is represented regional Zone Full simultaneously.
See also Fig. 5, it is that the many networks of the present invention are total to paging method the 4th embodiment schematic flow sheet under the coverage condition.Present embodiment comes down to combine aforementioned several embodiment, promptly working as UE is allowed to access under the situation of limited network and public network, on the one hand by CN based on whether comprising in the up-to-date UE location area information of knowing in advance of being preserved that special identifier determines that UE is current and whether be in the limited network, determine based on the current discrepancy information of its UE of knowing that UE is current by limited network access control node on the other hand and whether be in the limited network that the paging under the coverage condition is more accurate altogether to make many networks.
Whether comprise special identifier in the up-to-date UE location area information of step 510:CN according to its preservation and determine that UE is current whether in limited network.If CN determines that UE is current and is in the limited network, then change step 520 over to; Otherwise, change step 560 over to.
Step 520:CN changes step 530 over to then to the beep-page message of this UE of limited network access control node distributing paging.
Step 530: limited network access control node is based on the come in and go out current discrepancy information of limited network of the UE known, determines that this UE is current whether in the limited network scope.If then change step 540 over to; If not, then change step 550 over to.
Step 540: limited network access control node is the beep-page message by this UE of distributing paging that eats dishes without rice or wine directly, i.e. this UE of paging in the limited network overlay area.
Step 550: limited network access control node by the beep-page message of this UE of distributing paging that eats dishes without rice or wine, does not change step 560 over to then to the failure of CN answer page.
Step 560:CN is by public network access control node this UE of paging in the public network coverage.Certainly, for specific implementation is easy, this step also can be: CN is this UE of paging in the UE location area information that it is known is represented regional Zone Full by public network access control node and limited network access control node simultaneously.
See also Fig. 6, it is total to the network side paging device example structure schematic diagram under the coverage condition for the present invention realizes many networks.Described device in the present embodiment mainly comprises location area information memory cell 61, network determining unit 62 of living in, priority paging unit 63 and additional paging unit 64.Wherein, network determining unit 62 of living in can have multiple implementation, for example, it knows that by discrepancy information subelement 621 and first definite subelement 622 constitute, perhaps only determine that by second subelement 623 constitutes, perhaps know that by discrepancy information subelement 621, first definite subelement 622 and second definite subelement 623 constitute jointly.Also can there be multiple implementation priority paging unit 63, for example can be the first network priority paging unit, also can be the second network priority paging unit.Further describe the multiple implementation of its internal structure below in conjunction with the operation principle of network side paging device shown in this embodiment.
The network side paging device is preserved the UE location area information of knowing in advance by location area information memory cell 61, and on behalf of the zone, described location area information comprise first network's coverage area and second network's coverage area with overlapping region at least.Because preamble had been done in detail the UE position district information of knowing and had been introduced, thereby repeated no more herein.
When this UE of needs paging, this device is determined the concrete network of described UE present located by network determining unit 62 of living in then.The specific implementation of network determining unit 62 of living in comprises three kinds of situations at least:
One, network determining unit 62 of living in knows that by discrepancy information subelement 621 and first definite subelement 622 constitute jointly.Wherein, discrepancy information knows that subelement 621 is in order to know the come in and go out current discrepancy information of described first network of UE, and notify first to determine subelement 622 the described current discrepancy information, and then, determine that by first subelement 622 determines in the current coverage that whether is in first network of UE based on described current discrepancy information.
Its two, 62 of network determining units of living in determine that by one second subelement 623 constitutes.The suitable prerequisite of this situation is that first network adds a special identifier, be in the scope of first network coverage when reporting location area information if promptly UE is up-to-date, then comprise lane place data and special identifier in the up-to-date UE position district information that location area information memory cell 61 is preserved, described special identifier is in order to show in the current scope that is in first network coverage of this UE.So second determines whether subelement 623 comprises special identifier in just can the up-to-date UE location area information of position-based district information memory cell 61 preservations and determine in the current coverage that whether is in first network of described UE.
Its three, network determining unit 62 of living in knows that by discrepancy information subelement 621, first determines that subelement 622 and second determines that subelement 623 constitutes jointly.On the one hand, first determines that subelement 622 knows that based on discrepancy information the come in and go out current discrepancy information of first network of UE that subelement 621 provides determines that this UE is current and whether be in first network; On the other hand, second determines whether to comprise in the up-to-date UE location area information that subelement 623 position-based district information memory cells 61 preserve special identifier and determines in the current coverage that whether is in first network of described UE.
One, when comprising discrepancy information, 62 of network determining units of living in know subelement 621 and first definite subelement 622, or only comprise under the situation of second definite subelement 623, priority paging unit 63 can be the first network priority paging unit, when being in the coverage of first network for UE in order to the definite result who draws in network determining unit 62 of living in, preferential this UE of paging in described UE location area information is represented first network's coverage area in the zone.When definite result that network determining unit 62 of living in draws is in the coverage of first network for UE outside or during the priority paging failure of described priority paging unit 63, represent second network's coverage area or described location area information in the zone to represent this UE of paging in the regional Zone Full in this UE location area information by replenishing paging unit 64.
