Description

A kind of implementation method of calling user device

Technical field

The present invention relates to moving communicating field, be specifically related to the implementation method of a kind of calling user device (UE).

Background technology

In present applied communication network, when Mobility Management Entity (MME) will be set up business for the UE that is in idle condition, (Tracking Area, TA) paging was carried out to UE in Nei all base stations to need its tracking area of managing of control.Described MME is the Mobility Management Entity that UE is related to signaling plane, is presented as service universal grouping wireless business supporting node (SGSN) etc. in the 3G communication network usually.Concrete paging principle as shown in Figure 1.

Among Fig. 1, include UE and base station among the TA of MME management, wherein, the black rectangle is represented UE, and the grey round dot is represented the base station.Be connected with switch 120 between MME 110 and switch 130, the switch 140, switch 130, switch 140 link to each other with part or all base station in the TA respectively.In actual applications, as switch 130, switch 140 the switch of close base station link to each other with the base station by radio network controller (RNC).Usually the switch of close base station can be called the base station side switch.

Certainly, also can remove one or two switch in the switch 120,130,140, as long as guarantee that MME 110 can be by the base station communication among remaining switch and the TA.

When MME 110 will set up business for the UE that is in idle condition, MME carried out the UE paging with the base station that mode of unicast is controlled in the whole TA.

Particularly, for each base station among the TA, MME sends a paging command that comprises this Base Station Identification, UE identify label at least; All paging command that send to all base stations at first can be received by switch 120, afterwards switch 120 according to self routing configuration and paging command in the Base Station Identification that comprises, the paging command of receiving is sent to the base station among the TA by switch 130, switch 140.The base station receives after the paging command by paging channel paging UE, UE receive its return page response to the base station during paging of resident base station, this base station and then transmit these page responses to MME 110; MME 110 receive from the base station at the page response of UE the time, determine UE in this signal of base station coverage, and then carry out follow-up business operations such as business foundation by this base station and UE.

By the above as seen, because MME carries out the UE paging with the base station that mode of unicast is controlled in the whole TA at present, the base station number of adding in the TA is general more considerable; Therefore MME can send a large amount of paging command to the base station side switch when paging UE, and so a large amount of signaling traffics must take a large amount of transfer resources such as link bandwidth, causes the power system capacity of communication network to be subjected to obvious influence; And communication qualities such as the communication delay that the taking of transfer resource also certainly will have influence on UE, transmission rate cause the communication quality of UE with the network side proper communication time to descend; Have, above-mentioned signaling traffic is big, transfer resource is occupied, the degradation problem also can make user satisfaction obviously reduce under the UE communication quality again.

Embodiment

Below in conjunction with drawings and the specific embodiments to the detailed description of the invention.

The implementation method of paging UE provided by the invention is determined the prediction paging zone at UE place, and the UE paging is carried out in all base stations in the control prediction paging zone.And, at all right paging method of further using multicast in the TA of the pairing UE of high-quality business; Whether have, can also be that senior contracted user carries out different paging operations according to UE further again.

Referring to Fig. 2, Fig. 2 is the paging UE flow chart of a preferred embodiment of the present invention, and this flow process may further comprise the steps:

Step 210 is determined professional for UE foundation to step 220:MME, and judges whether the business that will set up is high-quality business, if enter step 230; Otherwise, enter step 240.

Particularly, when MME receives at the service request of UE or business information, MME determines and will set up professional for UE, and use prior art and read (QoS) information that comprises in the service request received or the business information, judge according to the QoS information that reads whether the business that will set up for UE be high-quality business.

Described determination methods is generally: MME reads the qos parameter that comprises in the QoS information, whether the value with the qos parameter that reads is compared with the parameter threshold value that sets in advance, and be high-quality business according to service request or the pairing business of business information that comparative result determines to comprise this qos parameter.

Particularly, the qos parameter that is used to carry out described judgement normally embodies the messaging parameter of QoS, as: as described in participating in the qos parameter of judgement be comprise in the QoS information with the corresponding service priority of type of service, or the communication delay that comprises in the QoS information etc.

If as the qos parameter that participates in judging, the described parameter threshold value of She Zhiing then is a service priority parameter threshold value so with service priority; Concrete deterministic process is: MME reads the service priority that comprises in the QoS information, compare with the service priority threshold value that sets in advance with the service priority that reads, if the service priority that reads is higher than the service priority threshold value of setting, service request or the pairing business of business information that MME determines to comprise described service priority are high-quality business; Otherwise service request or the pairing business of business information that MME determines to comprise described service priority are not high-quality business.

If as the qos parameter that participates in judging, the described parameter threshold value of She Zhiing then is the communication delay threshold value so with communication delay; Concrete deterministic process is: MME reads the communication delay that comprises in the QoS information, compare with the communication delay threshold value that sets in advance with the communication delay that reads, if the communication delay that reads is less than the communication delay threshold value that is provided with, service request or the pairing business of business information that MME determines to comprise described communication delay are high-quality business; Otherwise service request or the pairing business of business information that MME determines to comprise described communication delay are not high-quality business.

In actual applications, the qos parameter that is used to carry out described judgement also can not be a messaging parameter, but a plurality of messaging parameter, as: as described in participating in the qos parameter of judgement be comprise in the QoS information as described in service priority and communication delay etc.In this case, MME then need participate in the qos parameter of described judgement at service priority, communication delay etc., carries out aforesaid corresponding decision operation respectively; Only when the service request of determining to comprise each messaging parameter respectively or the pairing business of business information are high-quality business, service request or the pairing business of business information that MME just determines to comprise each messaging parameter are high-quality business.

Paging is carried out to UE in all base stations that step 230:MME controls in its TA that manages, and process ends.

Particularly, MME can carry out paging with clean culture or multicast mode control base station.When MME controlled all base stations in the TA UE is carried out paging in the mode of clean culture, the concrete grammar that paging is carried out in the control base station was identical with corresponding paging method of the prior art.

When MME will control all base stations in the TA UE is carried out paging with multicast mode, need with TA in the base station side switch that links to each other of base station in set in advance corresponding relation between this base station side switch is connected the base station in TA sign and the TA multicast sign, exchange function with the assurance base station side and will send to the base station from the paging command of MME according to this corresponding relation of setting.Certainly, this corresponding relation also can be arranged in other communication equipment, as long as the base station side switch can obtain in the time of need knowing this corresponding relation smoothly.

After finishing correspondence setting, MME just can carry out paging to UE with all base stations that multicast mode is controlled in the TA, and the concrete grammar that paging is carried out in the control base station is:

For the base station side switch that links to each other with base station among the TA, MME only sends a paging command that comprises TA multicast sign, UE identify label at least to each base station side switch.When the base station side switch is received from the paging command of MME, read the TA multicast sign in this paging command; And according to the corresponding relation between sign that in TA, connects the base station and TA multicast sign that sets in advance, determine that the TA multicast that reads identifies pairing Base Station Identification, the described paging command that will receive again sends to the pairing base station of definite Base Station Identification.

Base station in the TA receives after the paging command of MME by paging channel paging UE, UE receive its return page response to the base station during paging of resident base station, this base station and then transmit this page response to MME; MME receive from the base station at the page response of UE the time, determine UE in this signal of base station coverage, and then carry out follow-up business operations such as business foundation by this base station and UE.

Step 240: determine the prediction paging zone at UE place in TA, concrete prediction paging zone determines that method will describe in detail in Fig. 5.

The UE paging is carried out in base station in the step 250:MME control prediction paging zone.

Particularly, MME can carry out paging with clean culture or multicast mode control base station.

When paging was carried out to UE in the base station when MME controls the prediction paging zone in the mode of clean culture in, for each base station in the prediction paging zone, MME sent a paging command that comprises this Base Station Identification, UE identify label at least; The switch that the paging command that sends to described base station can be connected between MME and the base station receives, and by this switch according to self routing configuration and paging command in the Base Station Identification that comprises, the paging command of receiving is sent to the pairing base station of described Base Station Identification.

Before MME will carry out paging to UE with the base station in the multicast mode control prediction paging zone, need with base station side switch that the base station of prediction in the paging zone links to each other in set in advance corresponding relation between sign that this base station side switch institute in the prediction paging zone is connected the base station and the paging zone multicast sign, exchange function with the assurance base station side and will send to the base station from the paging command of MME according to this corresponding relation of setting.Certainly, this corresponding relation also can be arranged in other communication equipment, as long as the base station side switch can obtain in the time of need knowing this corresponding relation smoothly.

After finishing correspondence setting, MME just can carry out paging to UE with the base station in the multicast mode control prediction paging zone, and the concrete grammar that paging is carried out in the control base station is:

For the base station side switch that links to each other with the base station of prediction in the paging zone, MME only sends one to each base station side switch and comprises at least that the paging zone multicast identifies, the paging command of UE identify label.When the base station side switch is received from the paging command of MME, read the paging zone multicast sign in this paging command; And according to the corresponding relation between sign that in predicting paging zone, connects the base station and paging zone multicast sign that sets in advance, determine that the paging zone multicast that reads identifies pairing Base Station Identification, the described paging command that will receive again sends to the pairing base station of definite Base Station Identification.

Under rare occasion, UE may not be in the prediction paging zone, predicts that therefore UE can't paging be arrived in the base station in the paging zone.In this case, just there is not the base station to send page response in the prediction paging zone to MME; Therefore MME determines UE not in the prediction paging zone, and the UE paging is carried out in the base station in the control prediction paging antithesis district.Have, when MME also can surpass the standby threshold value that sets in advance at the standby time of UE, the UE paging was carried out in the base station in the control prediction paging antithesis district again.Described prediction paging antithesis district is meant the zone except that the prediction paging zone in the UE Acceditation Area.

Certainly, when UE was not in the prediction paging zone, MME also can control in the whole TA or clean culture or multicast paging are carried out to UE in the base station in the UE Acceditation Area.Described UE Acceditation Area is meant that UE uses the communication zone that prior art is registered in communication entities such as MME, HSS, and UE does not need to carry out operations such as regional registration, position renewal when mobile usually in its Acceditation Area.The UE Acceditation Area is exactly TA usually; Certainly, the UE Acceditation Area also may be some zone in the TA scope, or also includes other zone except that TA.In actual applications, when UE is not in the prediction paging zone, whether in prediction paging antithesis district, whole TA or UE Acceditation Area, carry out the UE paging, need usually to determine according to operation logic that sets in advance or service attribute etc.

In fact, UE paging in whole TA or in the UE Acceditation Area and the UE paging that describes below are basic identical, and key difference only is: before the paging when sign corresponding relation of institute's foundation in advance and paging at the base station all relate to base station in whole TA or the UE Acceditation Area.Following paging is that example is described with the UE paging in the prediction paging antithesis district just.

Particularly, MME can carry out the UE paging with the base station in clean culture or the multicast mode control prediction paging antithesis district.

When the UE paging was carried out in the base station when MME controls prediction paging antithesis district in the mode of clean culture in, for each base station in the prediction paging antithesis district, MME sent a paging command that comprises this Base Station Identification, UE identify label at least; The switch that the paging command that sends to described base station can be connected between MME and the base station receives, and by this switch according to self routing configuration and paging command in the Base Station Identification that comprises, the paging command of receiving is sent to the pairing base station of described Base Station Identification.

Before MME will carry out the UE paging with the base station in the multicast mode control prediction paging antithesis district, need with prediction paging antithesis district in the base station side switch that links to each other of base station in set in advance corresponding relation between sign that this base station side switch institute in prediction paging antithesis district is connected the base station and the prediction paging antithesis district multicast sign, exchange function with the assurance base station side and will send to the base station from the paging command of MME according to this corresponding relation of setting.Certainly, this corresponding relation also can be arranged in other communication equipment, as long as the base station side switch can obtain in the time of need knowing this corresponding relation smoothly.

After finishing correspondence setting, MME just can carry out paging to UE with the base station in the multicast mode control prediction paging antithesis district, and the concrete grammar that paging is carried out in the control base station is:

For the base station side switch that links to each other with base station in the prediction paging antithesis district, MME only sends one to each base station side switch and comprises at least that prediction paging antithesis district multicast identifies, the paging command of UE identify label.When the base station side switch is received from the paging command of MME, read the prediction paging antithesis district multicast sign in this paging command; And connects the sign of base station and predict the corresponding relation of paging antithesis district multicast between identifying from institute in prediction paging antithesis district according to what set in advance, determine that the prediction paging antithesis district multicast that reads identifies pairing Base Station Identification, the described paging command that will receive again sends to the pairing base station of definite Base Station Identification.

No matter be to predict paging zone or paging UE in prediction paging antithesis district, no matter be also with clean culture or with multicast mode paging UE, the base station all can received after the paging command of MME by paging channel paging UE, UE receive its return page response to the base station during paging of resident base station, this base station and then transmit this page response to MME; MME receive from the base station at the page response of UE the time, determine UE in this signal of base station coverage, and then carry out follow-up business operations such as business foundation by this base station and UE.

As shown in Figure 2, when MME determined to be not high-quality business for the business that UE sets up, MME can be with the base station calling UE in clean culture or the multicast mode control prediction paging zone.In actual applications, can should under which kind of situation, carry out described paging so that MME is definite by decision logic is set, and under which kind of situation, carry out described paging in the multicast mode with mode of unicast.The paging UE flow process that has added decision logic as shown in Figure 3, this flow process may further comprise the steps:

Step 310 is determined professional for UE foundation to step 320:MME, and judges whether the business that will set up is high-quality business, if enter step 330; Otherwise, enter step 340.

Concrete definite method and determination methods are identical with correlation method among Fig. 2 respectively.

Paging is carried out to UE in all base stations that step 330:MME controls in its TA that manages, and process ends.The method of operation of this step is identical with the method for operation of step 230.

Step 340: in TA, determine the prediction paging zone at UE place, and judge whether UE is senior contracted user, if, enter step 350, and process ends; Otherwise, enter step 360.Concrete prediction paging zone determines that method will describe in detail in Fig. 5.

Described determination methods is generally: MME obtains or reads the UE CAMEL-Subscription-Information of self storing from HSS, and whether judge has senior contracted user's sign, if having, MME determines that UE is senior contracted user in the UE CAMEL-Subscription-Information; Otherwise MME determines that UE is not senior contracted user.

Certainly, also can send the signatory rank querying command of the user who comprises the UE identify label to HSS by MME; HSS receives from behind the signatory rank querying command of the user of MME, read the UE identify label that comprises in this order, and search the pairing UE CAMEL-Subscription-Information of the UE identify label of reading, judge again whether senior contracted user's sign is arranged in the UE CAMEL-Subscription-Information that finds, if have, HSS determines that UE is senior contracted user, and return the signatory rank inquiry response of the user who comprises UE identify label and successful inquiring sign to MME, MME receives the signatory rank inquiry response of this user and reads wherein successful inquiring sign, determines that the pairing UE of UE identify label that comprises in the signatory rank inquiry response of this user is senior contracted user; Otherwise, HSS determines that UE is not senior contracted user, and return the signatory rank inquiry response of the user who comprises UE identify label and inquiry failure sign to MME, MME receives the signatory rank inquiry response of this user and reads wherein inquiry failure sign, determines that the pairing UE of UE identify label that comprises in the signatory rank inquiry response of this user is not senior contracted user.

Step 350:MME carries out paging with the base station in the mode of unicast control prediction paging zone to UE.The paging method of this step is identical with corresponding clean culture paging method in the step 250.

Step 360:MME carries out paging with the base station that the multicast mode is controlled in the prediction paging zone to UE.The paging method of this step is identical with corresponding multicast paging method in the step 250.

Identical with principle described in Fig. 2, if applying step 350 and step 360 can't paging arrive UE, MME then determines UE not in the prediction paging zone, and the UE paging is carried out in the base station in the control prediction paging antithesis district; It is identical with corresponding paging method in the step 250 that the method for UE paging is carried out in base station in the MME control prediction paging antithesis district.

Be example with Fig. 4 below, be described in the flow process of paging UE in the prediction paging zone.Flow process shown in Figure 4 may further comprise the steps:

Step 401:HSS determines the paging zone at UE in TA.Determining that this operation of paging zone is the prerequisite that MME carries out the multicast paging, also is to be that UE determines the basis of prediction paging zone, and in fact the prediction paging zone of determining for UE is exactly some in all paging zones that TA comprised.

The concrete grammar of determining paging zone is: set in advance monitoring time length and delivery flow rate threshold value, HSS uses prior art and reads in each cell communication record in the TA that preserves in the monitoring time length in the past, and the communications flow at UE that comprises in the cell communication record is compared with the delivery flow rate threshold value of setting; When the delivery flow rate threshold value is low relatively, HSS determines that it is the relatively active sub-district of communicating by letter with UE that described cell communication writes down pairing sub-district, and will be the center with this sub-district, be that the zone of radius is as the paging zone at UE with the integral multiple of this sub-district useful signal distance.

Certainly, also can set in advance the delay threshold value, and the delay duration at UE that comprises in the cell communication record that reads be compared with the delay threshold value of setting by HSS; When being detained threshold value when low relatively, HSS determines that it is often resident sub-district of UE that described cell communication writes down pairing sub-district, and will be the center with this sub-district, be that the zone of radius is as the paging zone at UE with the integral multiple of this sub-district useful signal distance.

In actual applications, the described paging zone that HSS determines in TA has a plurality of usually, and therefore, HSS can also guarantee not exist between each paging zone superimposed coverage area as far as possible when determining paging zone, to guarantee the reasonability of determined paging zone.

Have again, after HSS application of aforementioned method has been determined paging zone, the zone that also exists not paged as yet district to cover usually among the TA, HSS can further totally be defined as these zones a paging zone; Like this, the Zone Full among the TA just has been divided into different paging zones.

Step 402: because in fact the prediction paging zone of determining for UE is exactly some in all paging zones that TA comprised, adding needs to set in advance Base Station Identification and the paging zone multicast corresponding relation between identifying before the paging UE in the prediction paging zone.So, know in the paging zone as HSS when paging area information such as adding, delete the base station changes, the paging area information after changing need be carried on the base station that sends in the paging area information updating message in the paging zone; The corresponding former paging area information of preserving is upgraded in the base station with the paging area information that comprises in the paging area information updating message of receiving.

HSS knows that the method for paging area information variation is a lot, as: the paging area information after operating personnel directly will change sends to HSS; Or during the paging area information of operating personnel's typing in operation maintenance center (OMC) after changing, OMC sends to HSS with the paging area information of receiving.

Described paging area information generally includes: the pairing paging zone multicast of paging zone sign, and the corresponding relation between the sign of base station identifies with the paging zone multicast in the paging zone, paging zone routing iinformation etc.

Step 403: the switch that the paging area information after the base station will be upgraded sends to MME and links to each other with self, MME and switch upgrade the corresponding former paging area information of self preserving with the paging area information of receiving when receiving from the paging area information after the renewal of base station.In this step, Internet Group Management Protocol is generally used in the base station, and (Internet Group Management Protocol IGMP) communicates with switch, MME alternately.

Step 404:MME determines professional for UE foundation, and sends the prediction paging area information request that comprises the UE identify label to HSS.

Step 405:HSS determines the prediction paging zone at UE place in TA, concrete prediction paging zone determines that method will describe in detail in Fig. 5.

Step 406:HSS will be carried on for the paging area information of the definite prediction paging zone of UE in the prediction paging zone communication information and send to MME.

When step 407:MME receives from the prediction paging zone communication information of HSS, read and preserve the paging area information that comprises in this message at UE.

Step 408:MME is according to the corresponding relation between the Base Station Identification that comprises in the paging area information at UE of preserving and the paging zone multicast sign, comprises at least to each one of base station side switch transmission that links to each other with base station in the described prediction paging zone that the paging zone multicast identifies, the paging command of UE identify label.When the base station side switch is received from the paging command of MME, read the paging zone multicast sign in this paging command; And according to the corresponding relation between sign that in predicting paging zone, connects the base station and paging zone multicast sign that sets in advance, determine that the paging zone multicast that reads identifies pairing Base Station Identification, the described paging command that will receive again sends to the pairing base station of definite Base Station Identification.

Step 409: receive after the paging command of MME by paging channel paging UE the base station.

Step 410:UE receive its return page response to the base station during paging of resident base station.

Step 411: this page response is transmitted to MME in the base station of receiving page response; MME receive from the base station at the page response of UE the time, determine UE in this signal of base station coverage, and can carry out subsequent business operation by this base station and UE.Concrete subsequent operation may for: UE sets up user's face with the base station and is connected, and connects with the base station by user's face of setting up and to carry out data communication.

In actual applications, also can before step 404, carry out the operation of step 405 to step 407, but since in this case HSS do not know to want which UE of paging as yet, so HSS need carry out the operation of step 405 to step 407 at all UE among the TA.Like this, MME just can choose the paging area information at this UE, and carry out follow-up paging operation when determining to set up business for certain UE among the TA from the numerous paging area information from HSS.

Have, HSS can periodically determine the prediction paging zone of UE again, if HSS is inequality at twice determined prediction paging zone before and after the same UE, HSS needs and will send to MME for the pairing paging area information of prediction paging zone that UE determines for the last time so; MME then uses the paging area information of upgrading original this UE that preserves from the UE paging area information of HSS.

Making a general survey of Fig. 2 to Fig. 4 is not difficult to find that the description among Fig. 2 to Fig. 4 is embodiment.In actual applications, carrying out the UE paging in the prediction paging zone of UE is most important operation, and judgement of carrying out before the paging that relates to quality of service and the judgement that relates to the contracted user are not most important operations, and the follow-up business operation after the paging is not most important operation equally.As seen, in actual applications, can directly in the prediction paging zone of UE, carry out the UE paging; Also can before paging, further relate to the operation that quality of service is judged and/or the contracted user judges; Can also after paging, carry out the follow-up business operation.And, when reality is carried out paging to UE, no matter be in the prediction paging zone, still in prediction paging antithesis district, still in whole TA or UE Acceditation Area; Can carry out the UE paging with clean culture or multicast mode.

Such as:

First kind of mode of operation: further whether the business that will set up for UE of judgement be high-quality business before UE is carried out paging, and paging is carried out to UE in all base stations in judged result is the TA that control UE Acceditation Area or MME are managed when being.

Second kind of mode of operation: before UE is carried out paging, further judge whether UE is senior contracted user, and whether be that senior contracted user's judged result is carried out different UE paging operations according to UE, as: when UE was senior contracted user, MME carried out the UE paging with all base stations in the mode of unicast control prediction paging zone; When UE was not senior contracted user, MME then carried out the UE paging with all base stations that the multicast mode is controlled in the prediction paging zone.

The third mode of operation: further whether the business that will set up for UE of judgement be high-quality business before UE is carried out paging, and paging is carried out to UE in all base stations in judged result is the TA that control UE Acceditation Area or MME are managed when being; And continue to judge whether UE is senior contracted user for not the time in judged result, and whether be that senior contracted user's judged result is carried out different UE paging operations according to UE, as: when UE was senior contracted user, MME carried out the UE paging with all base stations in the mode of unicast control prediction paging zone; When UE was not senior contracted user, MME then carried out the UE paging with all base stations that the multicast mode is controlled in the prediction paging zone.

All relate to this operation of prediction paging zone of determining the UE place among above-mentioned Fig. 2 to Fig. 4, concrete definite method as shown in Figure 5.Among Fig. 5, determining method based on the paging zone of describing among Fig. 4, is P1, P2 and three paging zones of P3 with the area dividing that TA comprised; Certainly, can further P1, P2 and P3 still unlapped zone in TA be defined as paging zone a: P4, the coverage of P4 is represented with ledgement.

When determining the prediction paging zone at UE place, HSS can use prior art by with UE last resident base station alternately to know the position of this base station; Or use prior art by UE last resident base station obtain the rearmost position of UE when once resident, and with the UE position informing HSS that obtains.What no matter HSS obtained is base station location or UE position, and HSS can obtain to be the center, to be the zone of radius with the product of the UE translational speed of UE position update cycle and network support with this position that obtains.Afterwards, the superimposed coverage area maximum among the described zone that HSS relatively obtains and P1, P2, P3, the P4 between which paging zone, and the paging zone that will comprise maximum superimposed coverage area is defined as the prediction paging zone at UE place.

The described UE position update cycle is that UE application prior art is carried out position renewal institute's interlude cycle, uses prior art among the HSS and has set in advance this cycle; The described UE translational speed of network support is to use prior art to set in advance messaging parameter in the base station, represents with the maximum translational speed of UE of base station can be with the UE proper communication time usually; Or with the translational speed scope classification of UE, and wherein the maximum translational speed of certain one-level such as UE one-level of living in is expressed as the described UE translational speed of network support; Certainly, in different communication systems, also the current translational speed of the UE that communication entities such as base station record might be expressed as the described UE translational speed of network support.

Particularly, a lot of in order to the method that records the current translational speed of UE, as: the quantity of the tracking areas such as sub-district that record UE was crossed in one period continuous time draws UE with this and crosses over the frequency of tracking areas such as sub-district as the current translational speed of UE.

In actual applications, also can substitute the described UE position update cycle with the standby time of UE.Described UE standby time is usually expressed as the time difference between the moment of current paging UE and nearest moment that UE is in active states such as state of activation, and this time difference is generally calculated and be notified to communication entities such as HSS by the base station.

Have again, also can use such prediction paging zone and determine method: HSS uses prior art and reads in each cell communication record in the TA that preserves in the monitoring time length in the past, determines that according to the cell communication record that reads professional sub-district once took place UE in monitoring time length; Relatively the superimposed coverage area maximum between which paging zone among professional sub-district and P1, P2, P3, the P4 once took place in UE again, and the paging zone that will comprise maximum superimposed coverage area is defined as the prediction paging zone at UE place.

As seen, no matter use which kind of above-mentioned prediction paging zone and determine method, HSS can determine the zone that will compare superimposed coverage area with P1, P2, P3 and P4, suppose that this zone is the circular shaded that includes UE 510 among Fig. 5, and HSS is by relatively determining the superimposed coverage area maximum between this circular shaded and the paging zone P3, and HSS just determines that paging zone P3 is the prediction paging zone at UE place so.

Also have a kind of practical prediction paging zone to determine method, this method will be based on the Acceditation Area of UE.With Fig. 5 is example, supposes that P1 and P3 are the Acceditation Areas of UE, obtain UE 510 last resident base station location, or by UE 510 last resident base station obtain the rearmost position of UE 510 when once resident; Reentry and be the center, be the zone of radius with UE 510 translational speeds of network support and the product of UE 510 position update cycle/standby times with base station location/UE 510 positions that obtain; Afterwards, relatively zone of Huo Deing and the equitant part of UE 510 Acceditation Areas, and lap is defined as the prediction paging zone at UE 510 places.That is: after having determined to compare the described zone (supposing that this zone is the circular shaded that includes UE 510 among Fig. 5) of superimposed coverage area with P1, P2, P3 and P4, compare UE Acceditation Area and the equitant part of described circular shaded, and this lap (representing with vertical moulding) is defined as the prediction paging zone at UE place.

In addition, the UE standby time can also be compared with described standby threshold value, and when the UE standby time has surpassed the standby threshold value, the Acceditation Area of UE is defined as the prediction paging zone at UE place.

The circular shaded that is comprised among the Fig. 5 that obtains can be called the UE motor area; And, usually the nearest moment and the once resident rearmost position of UE that UE are in active state are stored among the MME, the mode of preserving is generally: add two fields in the UE context of being preserved in communication entities such as MME (context), these two fields are respectively the moving positions (active position) of movable (the active time) constantly in the moment of expression UE when being in active state at last and the expression UE position when being in active state at last.Described active position can represent with the sign of base station.

In actual applications, MME also can obtain from HSS and determine the required above-mentioned communication information of prediction paging zone, and uses the prediction paging zone that said method is determined the UE place.

In order to help to understand, below application drawing 6 to Fig. 8 principle when UE carried out paging is briefly described under the different situations, the black rectangle among each figure is represented UE, the grey round dot is represented the base station.Wherein, Figure 6 shows that the schematic diagram of paging UE when MME will set up high-quality business for UE; Figure 7 shows that when MME will set up non-high-quality business for UE schematic diagram with mode of unicast paging UE; Figure 8 shows that when MME will set up non-high-quality business for UE schematic diagram with multicast mode paging UE.

Among Fig. 6, MME 610 determines that the business that will set up for UE is a high-quality business, thereby MME610 only sends a paging command that comprises TA multicast sign, UE identify label at least to base station side switch 630,640 respectively by switch 620.When base station side switch 630,640 is received from the paging command of MME610, read the TA multicast sign in this paging command; And respectively according to the corresponding relation between sign that in TA, connects the base station and TA multicast sign that sets in advance, determine that the TA multicast that reads identifies pairing Base Station Identification, the described paging command that will receive again sends to the pairing base station of definite Base Station Identification.

Among Fig. 7, MME 710 determines that the business that will set up for UE is not a high-quality business, and definite UE is senior contracted user; Thereby determine the prediction paging zone P3 at UE places by HSS 700, and MME 710 sends a paging command that comprises this Base Station Identification, UE identify label at least in each base station in prediction paging zone P3 respectively by switch 720; The paging command that sends to described base station can be received by switch 730,740, and by switch 730,740 according to self routing configuration and paging command in the Base Station Identification that comprises, the paging command of receiving is sent to the pairing base station of described Base Station Identification.

Among Fig. 8, MME 810 determines that the business that will set up for UE is not a high-quality business, and definite UE is not senior contracted user; Thereby determine the prediction paging zone P3 at UE places by

HSS

800, and 810 of MME send paging command that comprise paging zone multicast sign, UE identify label at least to base station side switch 830,840 respectively by switch 820.When base station side switch 830,840 is received from the paging command of MME 810, read the paging zone multicast sign in this paging command; And according to the corresponding relation between sign that in predicting paging zone P3, connects the base station and paging zone multicast sign that sets in advance, determine that the paging zone multicast that reads identifies pairing Base Station Identification, the described paging command that will receive again sends to the pairing base station of definite Base Station Identification.

Fig. 6 to Fig. 8 is just in order simply to introduce the principle of the invention, and connected mode between involved switch quantity, each communication equipment in the practical application, definite prediction paging zone etc. may be different.

Described paging zone multicast sign is normally used commonplace multicast address at present.

In sum, can briefly describe the critical workflow of paging UE with Fig. 9, Fig. 9 is a paging UE general flow chart of the present invention, and this flow process mainly may further comprise the steps:

Step 910: the prediction paging zone of determining the UE place.

The UE paging is carried out in base station in the step 920:MME control prediction paging zone.

By the above as can be seen, the implementation method of paging UE provided by the present invention is determined the prediction paging zone at UE place, carries out the UE paging by all base stations in the MME control prediction paging zone; Signaling traffic in the time of can obviously reducing paging UE, required transfer resources such as Radio Resource when saving paging UE improve user satisfaction.And, at all right paging method of further using multicast in the TA of the pairing UE of high-quality business, the signaling traffic when obviously having reduced paging UE.Have again, can also be further predict clean culture paging in the paging zone, predict multicast paging in the paging zone at the UE that is not senior contracted user at the UE that is senior contracted user; This paging mode has considered that most of UE are not senior contracted user's situations, therefore the signaling traffic in the time of can further obviously reducing paging UE, required Radio Resource and the cable resource between MME and the base station side switch when obviously having saved paging UE.The minimizing of signaling traffic also helps the power system capacity that expands communication network, and helps improving the communication quality of UE, and user satisfaction is obviously improved.

And, can effectively save cable resource between MME and the base station side switch with multicast mode paging UE.Have, the reduction of signaling traffic also helps the power system capacity that expands communication network again; And saving wired, Radio Resource will reduce the communication delay of UE, improve the transmission rate of UE etc., all helps improving the communication quality of UE; Also have, above-mentioned signaling traffic reduces, saves advantages such as the communication resource, the raising of UE communication quality also can make user satisfaction obviously improve.
