Description
Technical field
The present invention relates to communication technical field, particularly a kind of paging method, mobile management network element and communication system.
Background technology
In mobile communication system, in order to save Radio Resource and subscriber equipment power saving, after a period of time do not have signaling and transfer of data, subscriber equipment can forward idle condition to.Under idle condition, the location of user equipment known to network is a larger wireless coverage area be comprised of several communities, is called registration area.When network need to send signaling or data to subscriber equipment, network side is by paging technique all cell paging subscriber equipment under idle condition in the registration area of subscriber equipment, subscriber equipment responds paging after receiving the beep-page message of issuing oneself, the communication of foundation and network side, forward connection status to.The registration area of a subscriber equipment often is comprised of tens of up to a hundred communities, because subscriber equipment at a time only can reside in the definite position (community) in registration area, therefore, if all cell paging subscriber equipment in the user equipment registration zone, although can guarantee that Quick Paging, to subscriber equipment, can produce very high paging load.
The method of existing layering paging, suppose most of subscriber equipmenies in the time of majority all in basic inactive state.The registration area of subscriber equipment is carried out to layering according to the granularity of distinct coverage region size, and granularity is less, and the subregion quantity of dividing in registration area is more, and single subregion area coverage is less; Otherwise granularity is larger, the subregion quantity of dividing in registration area is fewer, and single subregion area coverage is larger.Take the EPS system as example, the layering granularity can be from small to large community-<the eNodeB area of coverage-<tracking area TA-<tracking area list TA List.We claim that granularity and the less subregion of area coverage divided are lower region, and granularity of division and larger subregion are top area, and for example relatively, the area of community more little ，Ze community is lower region for community and tracking area, and tracking area is top area.
Therefore, adopt existing layering paging method, when paging is initiated, at first select a less lower region to carry out paging, if paging failure (not receiving page response), expanded scope, select a larger top area to continue paging, until paging success, or finally expand paging in the whole registration area of subscriber equipment to.
On each hierarchy of layer, can select a sub regions to carry out paging by certain algorithm.Usually the subscriber equipment that can select network to record is last resident subregion when nearest connection status, for example: on the layering granularity of community, select the community of subscriber equipment last access under the last connected state; On the layering granularity of the eNodeB area of coverage, select the subscriber equipment area of coverage of the eNodeB of access recently; On the layering granularity of tracking area, select the tracking area of subscriber equipment last access under the last connected state; In the superiors, i.e. the registration area of subscriber equipment itself, do not need the process selected and directly paging in whole registration area scope.
Move and do not need informing network in whole registration area owing to transfer Idle (free time) state to when subscriber equipment after, therefore in existing layering paging method, if the user is in mobile status, may leave current resident subregion and move to other subregions in registration area, thereby cause calling user device in resident subregion scope of the last time can't receive page response, now enlarge paging domain and carry out paging in top area, can waste the paging resource, and the time delay of increase business foundation.

While occurring according to paging, this subscriber equipment is set up for the first time signaling at described first layer upper strata subregion and is connected, and the time interval of this subscriber equipment between the last release signaling in described first layer upper strata connects obtained this residence time correlation measured value; Within this time interval, subscriber equipment is not set up signaling and is connected in other subregion of first layer upper strata.
In another one embodiment of the present invention, obtain the residence time correlation measured value of subscriber equipment in this first layer subregion, comprising:
Set up the number of times that signaling is connected according to mobile management network element with described subscriber equipment and obtain described residence time correlation measured value in described first layer subregion; During the described subscriber equipment of statistics is set up the number of times of signaling connection in described first layer subregion, subscriber equipment is not set up signaling and is connected in other subregion of described first layer.

Wherein, subscriber equipment is not set up signaling and is connected in other subregion of described first layer, be also that subscriber equipment is not set up the signaling connection in other first layer subregions outside affiliated first layer subregion, the subregion of this first layer is the subregion that obtains this subscriber equipment residence time correlation measured value, for example first layer is the TA layer, the subregion of first layer can be TA1 so, TA2......TAn, if obtaining residence time correlation measured value is in the TA1 zone, so described other subregions of first layer comprise: TA2......TAn.
In the present embodiment, the executive agent of above step is the mobile management network element of management paging flow process, this mobile management network element is the different network entity of correspondence in different networks, for example: global system for mobile communications (Global System for Mobile communications; GSM)/enhanced data rates for gsm evolution technology (Enhanced Data Rate for GSM Evolution; EDGE) wireless access network (GSM/EDGE Radio Access Network; GERAN)/at land radio access web (UMTS Territorial Radio Access Network; UTRAN), in, this mobile management network element is serving GPRS support node (Serving GPRS Support Node; SGSN) or (the Mobile Switching Center of mobile switching centre; MSC); In the UMTS Terrestrial radio access network (E-UTRAN) of evolution, this mobile management network element is Mobility Management Entity (Mobility Management Entity; MME), at worldwide interoperability for microwave access (Worldwide Interoperability for Microwave Access; WiMax) in network be access service node gateway (Access Service Network Gateway; ASN-GW), for the Mobility Management Entity in other networks, do not enumerate.
In the GPRS/UMTS system, registration area is Route Area (Routing Area), and in the grouping system EPS of evolution, registration area is tracking area list (Tracking Area List).
In various types of networks, the registration area of subscriber equipment has multiple division methods, for example: in the EPS network, can by the registration area of subscriber equipment by lower floor to upper strata can division of cells, the eNodeB area of coverage, four levels of tracking area and tracking area list.Wherein, the registration area that the superiors are subscriber equipment, that is to say, when in the failure of lower region calling user device, and finally can paging in the whole registration area of subscriber equipment.
It should be noted that, usually the scope that top area comprises lower region, for example: " the eNodeB area of coverage of user's recent visit " comprises " community of user's recent visit ", " tracking area of user's recent visit " comprises " community of user's recent visit " etc., but the coverage of a tracking area is usually large than the coverage of an eNodeB, so claim that interior " tracking area of user's recent visit " of registration area of subscriber equipment is top area, " the eNodeB coverage of user's recent visit " is lower region, but the tracking area of user's recent visit might not comprise the eNodeB overlay area of user's recent visit fully, both may be the relations of occuring simultaneously, in the layering paging scheme, what term lower floor and upper strata meaned is from small to large, progressively enlarge the process of paging range, do not mean that the top area of the last access of subscriber equipment necessarily comprises the lower region of the last access of subscriber equipment.
It should be noted that equally, according to the difference configuration of operator, the scope in the zone of tracking area likely is less than the scope that base station covers, and the scope of tracking area list area also likely is less than the scope that base station covers.
In embodiments of the present invention, the scope of Jin Yi community is less than the scope that base station covers, the scope that base station covers is less than the regional extent of tracking area, the scope that the regional extent of tracking area is less than the tracking area list area is that example describes, if first layer is cell coverage area, the first layer upper strata is base station coverage area, tracing area or tracking zone list zone;
Perhaps, if first layer be base station coverage area, the first layer upper strata is tracing area or tracking zone list zone;
If perhaps first layer is tracing area, the upper strata of first layer is the tracking zone list zone.
In all embodiment provided by the invention, residence time correlation measured value refers to the measured value of network to subscriber equipment residence time in selected subregion.In the mobile network, in order to save Internet resources and power saving, terminal is not after a period of time has signaling and transfer of data, can forward idle condition to, under idle condition, subscriber equipment does not need informing network while moving in the registration area scope, it is the accurate location that network side can't be known subscriber equipment, therefore network side in fact can't be definite knows the duration of subscriber equipment in certain sub regions scope, even as the user during in idle condition, whether network side can't know that subscriber equipment is current in this subregion scope, therefore, network side can only according to self the duration length of perceived information measurement subscriber equipment in this subregion, the judgement subscriber equipment is in the possibility size of this subregion, thereby whether determine calling user device in this subregion.
Concrete, mobile management network element can use the method for measurement of different residence time correlations and corresponding decision gate limit value to subscriber equipment the resident duration correlation in the subregion of particular hierarchical level measured.For example, when mobile management network element perceives subscriber equipment and enters the new subregion of of a certain hierarchy of layer (entering a Ge Xin community), mobile management network element can be designated this subregion the recent visit subregion of this hierarchy of layer, be reset at the residence time correlation measured value of this hierarchy of layer, then can be according to different method of measurement, cumulative this measured value.When the needs calling user device, mobile management network element can be by current residence time correlation measured value and corresponding threshold value relatively, whether to determine calling user device in the recent visit subregion of this hierarchy of layer.The decision gate limit value of different hierarchies of layer may be different.
As a kind of feasible execution mode, the registration area of a plurality of hierarchies of layer divide at to(for) subscriber equipment, can carry out respectively the measurement of residence time correlation at each hierarchy of layer, when the needs calling user device, can be from lower floor to upper strata, whether the residence time correlation measured value that judges respectively each hierarchy of layer is more than or equal to the threshold value that hierarchy of layer is set separately, if be more than or equal to the setting threshold value, the recent visit subregion at this hierarchy of layer carries out paging, otherwise skip this hierarchy of layer, further in top area, carry out calling user device.If a certain hierarchy of layer paging failure (not receiving the page response of subscriber equipment), in the subregion on this layering upper strata, carry out paging, until paging success (receiving the page response of subscriber equipment), or until expand in the whole registration area of subscriber equipment and carry out paging.
In the process by lower floor to upper strata calling user device, except from lower floor to upper strata step by step the mode of paging, consider that the business setup delay that calling user device unsuccessfully causes in lower region increases, the problems such as waste paging resource, can also carry out across the level paging from lower floor to upper strata.For example: can a paging community and two levels of tracking area list: at first in the community of subscriber equipment recent visit, carry out paging, if paging failure directly carries out paging in the scope of whole tracking area list; Perhaps can a paging eNodeB area of coverage, tracking area and three levels of tracking area list.Because an eNodeB serves a plurality of communities usually, these communities might not all belong to the current tracking area list scope of subscriber equipment, therefore at this level of the eNodeB area of coverage, can only at the area of coverage of eNodeB and the tracking area list common factor part of subscriber equipment, carry out paging.
The paging method that the embodiment of the present invention provides and mobile management network element, by mobile management network element obtain subscriber equipment the resident duration correlation measured value than in zonule judge whether this than zonule in the calling party, if measured value is less than the setting thresholding, skip this than zonule, enlarged area scope calling user.Abandon the calling user device at the low subregion of paging success rate by introducing the temporal correlation measurement, thereby realize the Quick Paging subscriber equipment, reduce the subscriber equipment access network and set up the time delay of communication with network side, save the paging resource.
The flow chart that Fig. 2 is paging method the second embodiment provided by the invention, as shown in Figure 2, the present embodiment describes with an object lesson in the EPS system: suppose to adopt the layering paging method by the registration area of subscriber equipment, be that tracking area list (Tracking Area List) is divided into 3 levels, be respectively eNodeB overlay area, tracking area and tracking area list from lower floor to upper strata.In the present embodiment, the residence time correlation adopts the method for measurement of resident duration.The mobile management network element that duty pager is controlled is MME.
Except the hierarchy of layer (being the tracking area list) of top layer does not need to measure the residence time correlation, MM E safeguards 3 variablees to each hierarchy of layer (being two hierarchies of layer of the eNodeB area of coverage and tracking area) in customer equipment context: 1) recent visit subregion sign; 2) enter the subregion timestamp; 3) rearmost position acknowledging time stamp.
The method specifically comprises:
S201, MME receive the subscriber equipment related signaling message from eNodeB, carry the recent visit subregion sign of subscriber equipment in this subscriber equipment related signaling message;
From the subscriber equipment related signaling message of eNodeB be divided into two classes, a kind of is that subscriber equipment sends to MME by the wireless connections with eNodeB foundation, for example: Attach Request message (Attach Request), tracing section updating request message (Tracking Area Update Request), service request information (Service Request) etc., eNodeB receives these subscriber equipment related signaling message, 7 send to MME after some extra information of affix in this subscriber equipment related signaling message, the recent visit subregion sign that may comprise subscriber equipment in these extra information, for example: cell ID, tracking area identification etc.Another kind is the signaling message that eNodeB itself produced and sent to MME, for example: the path handover request message in the Handover flow process (Path Switch Request), handoff notification message (Handover Notify), position message message in the report stream journey of position (Location Report) etc., eNodeB also can carry the recent visit subregion sign of subscriber equipment in these message.
Because eNodeB can set up fixing signaling transmission channel with MME, therefore in the process of setting up in signaling transmission channel, eNodeB can pass to MME by the eNodeB of oneself sign, MME preserves the corresponding relation of signaling transmission channel and eNodeB sign, and no longer need to be in every message all the eNodeB of affix oneself identify.
S202, MM E obtain the recent visit subregion sign of subscriber equipment from the message from eNodeB.
The service request information (Service Request) of take is example, MME obtains the current recent visit subregion sign of subscriber equipment from message, this recent visit subregion sign can be divided into different levels, comprise: cell ID, eNodeB sign and tracking area identification etc., because layering paging scheme is in the present embodiment only used eNodeB overlay area and tracking area two sub regions hierarchies of layer, do not use the community level, so MM E only safeguards the residence time correlation measured value of the eNodeB area of coverage and two hierarchies of layer of tracking area.
At each hierarchy of layer, MME compares the recent visit subregion sign of preserving in the recent visit subregion of the subscriber equipment of acquisition sign and customer equipment context, if both are not identical, the recent visit subregion of perhaps preserving in customer equipment context is designated sky (invalid), the recent visit subregion sign of the subscriber equipment that will obtain from message is kept in user's context, and will enter subregion timestamp field and be revised as the current time, the recent visit subregion sign that is the MME subscriber equipment that will obtain from message is kept at the time in user's context.If both are identical, now MME is not operated residence time correlation measurement relevant field in customer equipment context.
In the present embodiment, suppose that change has occurred the current up-to-date eNodeB sign of the subscriber equipment obtained from service request information, but tracking area identification is identical with the recent visit tracking area identification of preserving in customer equipment context, the eNodeB sign of the current up-to-date access of subscriber equipment that MME will obtain from service request information is kept in " recent visit eNodeB sign " field of customer equipment context, and upgrading " entering recent visit eNodeB timestamp " is the current time; Do not revise " recent visit tracking area identification " in customer equipment context " entering recent visit tracking area timestamp " field.
If the message of receiving is Attach Request message (Attach Request), MME thinks that subscriber equipment is from new position accesses network, therefore MME always the latest position area identification using the positional information of carrying in Attach Request message as subscriber equipment be kept in customer equipment context, and arrange that to enter subregion timestamp field be the current time, restart timing.
In the network environment coexisted at some multi-access technologies, user terminal may be switched to another kind of inserting technology networks from a kind of inserting technology networks, when the situation that another kind of inserting technology networks occurs to be switched to from current inserting technology networks, network side can keep its measured value of residence time correlation at each layering paging zone of current access technology, also can, by the zero clearing of correlation measured value, when switching back current inserting technology networks, next subscriber equipment restart statistics.
S203, subscriber equipment do not have data or signalling in a period of time, eNodeB initiates signaling Connection Release flow process, and subscriber equipment transfers idle condition to.MME is set to the current time by the rearmost position acknowledging time stamp of each hierarchy of layer in customer equipment context.Can see, on each hierarchy of layer, its rearmost position acknowledging time stamp always is later than and enters the subregion timestamp.
S204, under idle condition, network has signaling or data to send to subscriber equipment, MME needs at first calling user device.The paging method provided according to the embodiment of the present invention,, judged the residence time correlation measured value of each hierarchy of layer to upper strata by lower floor.
It should be noted that, S204 may be triggered during in idle condition at subscriber equipment, but subscriber equipment always can not trigger paging when idle condition, and therefore S203 can perform step S204 afterwards at every turn.
In the present embodiment, at first eNodeB area of coverage level is carried out to the judgement of residence time correlation, the setting threshold value of supposing the residence time correlation measured value (being resident duration) at eNodeB area of coverage hierarchy of layer is 3 minutes, 180 seconds, if it is 500 seconds that the eNodeB area of coverage hierarchy of layer of preserving in the upper customer equipment context of MME " rearmost position acknowledging time stamp " deducts the time interval that " entering the subregion timestamp " obtain, be more than or equal to the setting threshold value, the eNodeB area of coverage that " recent visit eNodeB sign " field that at first MME preserves in customer equipment context is preserved carries out paging, as previously described, only can further optimize and carry out paging at the area of coverage of this eNodeB and the tracking area list common factor part of subscriber equipment.If the paging success, paging flow process finishes; If subscriber equipment is response not, possible subscriber equipment has shifted out the area of coverage of the eNodeB of " the recent visit eNodeB sign " correspondence of preserving in the customer equipment context under idle condition.MME can enlarge paging domain, in higher level's hierarchy of layer continuation paging of eNodeB overlay area level, carries out S205.
If it is 110 seconds that two timestamps subtract each other the time interval obtained, be less than the setting threshold value, think that the probability of paging success is less under eNodeB area of coverage corresponding to " the recent visit eNodeB sign " of preserving in user's context, at this eNodeB area of coverage, do not carry out paging.MME enlarges paging domain, in higher level's hierarchy of layer continuation paging of eNodeB overlay area level, carries out S205.
S205, layering paging enter the tracking area hierarchy of layer.Suppose that the setting threshold value at " resident duration " measured value of tracking area hierarchy of layer is 8 minutes, 480 seconds, if it is 500 seconds that the tracking area hierarchy of layer of preserving in the upper customer equipment context of MME " rearmost position acknowledging time stamp " deducts the time interval that " entering the subregion timestamp " obtain, be more than or equal to the setting threshold value, the tracking area of " recent visit tracking area identification " Related fields of at first preserving in customer equipment context carries out paging.If the paging success, paging flow process finishes; If subscriber equipment is response not, possible subscriber equipment has shifted out the tracking area scope corresponding to " recent visit tracking area identification " of preserving in the customer equipment context under idle condition.MME continues to enlarge paging domain, in higher level's hierarchy of layer continuation paging of tracking area level, carries out S206.
If it is 400 seconds that two timestamps subtract each other the time interval obtained, be less than the setting threshold value, think that the probability of the following range paging success that " the recent visit tracking area identification " preserved is corresponding is less in user's context, at this tracking area, do not carry out paging.MME continues to enlarge paging domain, in higher level's hierarchy of layer continuation paging of tracking area level, carries out S206.
It should be noted that: if continue paging owing at lower region paging failure (without response), enlarging paging domain to upper strata paging domain, also can no longer judge whether terminal is greater than the setting threshold value at the resident correlation measured value of upper strata paging domain.
S206, layering paging enter the superiors zone, at the registration area of subscriber equipment, and paging in the whole tracking area list scope that MME is user equipment allocation.In the superiors zone, without measurement and the judgement of carrying out the residence time correlation, MME is calling user device in whole tracking area list scope directly again.If the user device responsive paging, calling user device success, if subscriber equipment without response, whole paging flow process failure.
The flow chart that Fig. 3 is paging method provided by the invention the 3rd embodiment, as shown in Figure 3, the present embodiment provides the another kind of method that subscriber equipment is measured in the residence time correlation of a certain hierarchy of layer subregion, set up number of times that signaling is connected as measured value by subscriber equipment and Mobility Management Entity, subscriber equipment may be by adhering to (Attach), service request (Service Request), tracing section updating (Tracking Area Update), switching flow processs such as (Handover) is set up signaling with MME and is connected, after setting up the signaling connection, if a period of time does not have signaling and transfer of data, eNodeB can trigger Mobility Management Entity and transfers subscriber equipment to idle condition, this is called " once " signaling and connects.
Similar with last embodiment, in the present embodiment, Mobility Management Entity, when each connection is set up, obtains the latest position subregion sign of subscriber equipment, and is recorded in customer equipment context from the message from eNodeB.With the difference of last embodiment, be: each subscriber equipment is connected with Mobility Management Entity while setting up, if the recent visit subregion of the subscriber equipment that Mobility Management Entity obtains from the message of eNodeB transmission sign is compared with the value of preserving in customer equipment context, do not change, the signaling connection that subregion of corresponding hierarchy of layer identifies is set up number of times and is added 1; If change, preserve the recent visit subregion identify and restart the counting.When paging occurs, if setting up the number of times accumulated value, the signaling connection that the corresponding hierarchy of layer subregion recorded in user's context is initiated is more than or equal to the setting thresholding, in this subregion, carry out paging; If be less than the setting threshold value, think that the probability of success of calling user device is less in this subregion, at this subregion, do not carry out paging, expanded scope is carried out paging in the higher level zone of this subregion, until the paging success, or carry out paging until expand the whole registration area of subscriber equipment to.
Subscriber equipment is set up after signaling connects and may be continued mobile and shift out the band of position that connects place while setting up, in the present embodiment, connect the unchanged measured value as estimating the probability of subscriber equipment in this subregion scope when paging occurs of the location of user equipment subregion obtained while setting up by continuous several times, the threshold value of the measured value of this number of times and setting is relatively determined whether to carry out paging in this subregion, the threshold value of setting is larger, relative, think that the probability of paging success in this subregion is just larger.
In the present embodiment, suppose that the layering paging scheme is by the registration area of subscriber equipment, i.e. 2 levels have only been divided in tracking area list, i.e. the tracking area list level of the community level of lower floor, and the superiors.The residence time correlation adopts signaling to connect the method for measurement of setting up number of times.Equally, the mobile management network element that duty pager is controlled is MME.
In the present embodiment, because the registration area of subscriber equipment has only been divided two levels, top layer tracking area list does not need to measure the residence time correlation, therefore MME safeguards 2 variablees to the unique layering subregion ，Ji of lower floor community in customer equipment context: 1) recent visit subregion sign; 2) connect and set up number of times in recent visit subregion signaling.
The method specifically comprises:
S301, subscriber equipment are set up signaling with MME and are connected.
Subscriber equipment and MME set up signaling and are connected to occur in and adhere to, the periodicity tracing section updating, under idle condition across the tracing section updating of tracking area list, service request, in the flow processs such as switching (Handover) across MME, subscriber equipment is set up Radio Resource with eNodeB and is connected, and sets up with MME and keep signaling to be connected by eNodeB.
Same, after eNodeB receives the signaling message from subscriber equipment, can in message, after some extra information of affix, send to MME, may comprise the recent visit subregion sign of subscriber equipment in these extra information, such as: cell ID, tracking area identification etc.
S302, MME obtain the recent visit subregion sign of subscriber equipment from the message from eNodeB.
In the present embodiment, in the layering paging method, only divided two-layer, therefore the signaling that MME only adds up the community layering of lower floor connects sets up number of times, MME obtains the cell ID while setting up the signaling connection from message, with " recent visit cell ID " field of preserving in customer equipment context, compare, if it is not identical, " the recent visit cell ID " perhaps preserved in customer equipment context is empty (invalid), the current up-to-date cell ID of the subscriber equipment that MME will obtain from message is kept in " recent visit cell ID " field of customer equipment context, and the value that " number of times is set up in signaling connection in recent visit community " is set is 1, if both are identical, MME adds 1 by the value that " in recent visit community signaling, connects and set up number of times " field in customer equipment context.
