For so that principle of the present invention, characteristic and advantage are clearer, describe the present invention below in conjunction with specific embodiment.
Embodiment one
If paging server such as home subscriber server HSS or machine type communication MTC server need UE in the group is carried out paging, at first, the mobile management network element that HSS or MTC Server UE in the group is corresponding (or in the mobile management network element tabulation each mobile management network element) sends group's paging request; Mobile management network element carries out group paging by corresponding access network elements to UE in the group, and UE disperses access network in the group before group's page response timer expiry.In addition, network side can the interior UE of each group who does not respond of independent paging.
With reference to Fig. 3, the mobile communication paging method that the present embodiment provides, flow process is as follows:
UE sends registration request in S101, the group, carries UE sign (such as IMSI) in this message; And carry group identification (such as Group ID or IMSI), to offer mobile management network element; Described registration request refers to that crowd interior UE carries out the request of registration, comprise the location area updating request LAU Request that adheres in the attachment flow in request AttachRequest, tracking area request TAU Request, the location area updating flow process or the Routing Area Update request RAU Request in the Routing Area Update flow process, access network elements can carry the residing positional information of UE in the group in registration request.
S102, mobile management network element obtain subscription data from HSS or MTC Server, and described subscription data is the subscription data of UE in the described group.
Comprise group identification in the subscription data.When mobile management network element creates context, can comprise group identification and/or UE sign, described group identification can be carried to mobile management network element (as described in step S101) or by MTC Server or HSS by UE provides group identification to bring mobile management network element.
For obtaining subscription data, mobile management network element sends a request message to HSS or MTC Server, subscription data with group under the subscription data that obtains UE or the UE, described request message can be to upgrade the message such as position requests Update Location Request or subscription data request Subscriber Data Request as the case may be, this request message portability UE sign or group identification.HSS or MTC Server receive that the backward mobile management network element of this request message sends the subscription data response message, this response message carries the subscription data of UE or group's subscription data, described response message can upgrade the message such as response Update LocationResponse or subscription data response Subscriber Data Response in the position as the case may be, and this message is optionally carried group identification.Obtaining alternately request and the response message type of subscription data between server and the mobile management network element can select as the case may be.
Described user contracting data can also comprise positional information, and positional information refers to Location Area Identification (perhaps Location Area Identification tabulation), cell ID (perhaps cell identification list), access network elements sign (perhaps access network elements identification list), tracking area identification (perhaps tracking area identification list) or Routing Area Identifier (perhaps Routing Area Identifier tabulation) etc. among the present invention.
So mobile management network element is except obtaining by user contracting data the positional information of crowd interior UE, the positional information that Access Network reports in the time of also can accessing by the user is determined the positional information of crowd interior UE.
S103, mobile management network element are accepted the registration request of UE in the group, send registration and accept message to UE in the group; Described registration accepts to refer to the message of UE registration request in the mobile management network element acceptance group, comprises Attach Accept, TAU Accept, LAU Accept or RAU Accept.If mobile management network element obtains group identification from HSS or MTC Server, then the portability group identification is given UE in the group.
The mobile management network element that above-mentioned S101-S103 step is described obtains in the method for group identification and positional information, and UE can be the behavior of a plurality of UE in some UE or the group in the described group.What describe in the subsequent step is the process of UE in the network side paging group, and UE refers to all UE in crowd interior a part of UE or the group in the group.
When S104, MTC Server or HSS need send paging request to UE in the group, MTC Server or HSS obtained the mobility management network element information of crowd interior UE;
MTC Server can obtain the mobile management network element of crowd interior UE from HSS or mobile management network element is tabulated or MTC Server is universe name (FQDN according to the positional information of UE in the group, Fully Qualified Domain Name), then carry out the domain name system DNS inquiry, obtain mobile management network element or the mobile management network element tabulation of crowd interior UE; The perhaps mobility management network element information of UE in the static configuration group among the MTC Server, described mobility management network element information refers to mobile management network element or the mobile management network element of group interior UE and tabulates.
The mobile management network element of S105, MTC Server or HSS UE in the group (perhaps all mobile management network elements in the mobile management network element tabulation) sends group's paging request, and (this step can be that MTC Server sends group's paging request to HSS, sends group's paging request to group one or more mobile management network element of interior UE by HSS; Perhaps MTC Server sends group's paging request to one or more mobile management network element; Perhaps HSS sends group's paging request to one or more mobile management network element.)
Carry group identification in the described group paging request message, go back the portability paging range, the zone that described paging range is determined according to the positional information of UE in the group, such as lane place, residential quarter, tracking area, Route Area, perhaps corresponding access network elements.Also portability is for the indication information that identifies same group's paging request for group's paging request message, and the indication information of same group's paging request is identical.Described indication information is whether be used to indicate the described group of crowd interior UE paging request be same group's paging request, for example described indication information can be Transaction Identifier, after UE receives a plurality of groups of paging requests of same transaction sign in the follow-up group within a period of time, only respond one of them group paging request and get final product, abandon group's paging request of all the other same transaction signs.
Described group paging request is that to be used for the message of UE in the paging group or described group's paging request be that MTC Server or HSS are used for the message that in group UE sends data or signaling for MTC Server or HSS, such as Group Paging Request or Paging Request or signaling transmission request or data sending request, the present invention is not called any restriction to the message name of described message.
Alternatively, mobile management network element starts group's paging timer, and described timer is used for whether UE responds group paging request in definite within a certain period of time group.
After S106, mobile management network element are received group paging request, can send group's paging request to all access network elements in the described paging range, perhaps the positional information according to UE in the group sends group's paging request to corresponding access network elements;
Carry group identification in described group's paging request message, also can comprise be used to the indication information that identifies same group's paging request.By a paging request can the paging group in all UE or a part of UE, reduce the ICQ amount, alleviate network burden.
S107, each access network elements carry out paging according to group identification to UE in the group, and paging request carries group identification, go back portability and are used to indicate the indication information whether group paging request is same group's paging request;
After UE receives group paging request in S108, the group, the group identification of determining group's paging request whether with self under group identification consistent, in this way, then respond described group's paging request, otherwise abandon described group's paging request.Optionally, UE determine whether receive identical indication information in a period of time group's paging request (for example whether Transaction Identifier is identical) of (namely whether indication group's paging request is the indication information of same group's paging request) in the group, if receive group's paging request of group interior identical indication information in a period of time, UE can abandon described group's paging request in the group, otherwise the described group of UE response paging request in the group, optionally, UE also can disperse to initiate page response in the group in group's page response timer scope, for example UE initiates page response at random in the group within a period of time, be after a lot of UE receive group paging request, can not initiate immediately page response.
Described group's page response timer is the timer of UE dispersion response group paging request in the group, for example group's page response timer Group Paging Response Timer.
The concentrated page response that UE disperses the initiation page response can reduce UE in a large amount of groups in the group among the present invention impacts network side and bears.Usually before initiating paging, network side (comprising mobile management network element, access network elements, HSS, MTC Server or other servers) can send to crowd interior UE with group's page response timer by the form of chain of command or data surface, specifically comprises following several mode:
Mode one: mobile management network element can send to crowd interior UE with described group page response timer by NAS message, and described NAS message comprises that adhering to the Routing Area Update that the location area updating of accepting in Attach Accept message, the location area updating flow process accepts in TAU Accept message or the Routing Area Update flow process in the attachment flow accepts RAU Accept message etc.
Mode two: access network elements can send to crowd interior UE with described group's page response timer by RRC message, and described RRC message includes but not limited to that radio bearer is set up Radio Bearer Setup message or RRC Connection Reconfiguration message etc. is reshuffled in the RRC connection.
Mode three, HSS or MTC Server or other servers (can be referred to as server, described server is preserved the group's page response timer of UE in the group) can pass through OMA DM (OpenMobile Alliance Device Management, open mobile alliance device management), the mode of OTA (OverThe Air, the aerial download), broadcasting or multicast sends to crowd interior UE with described group's page response timer.
Mode four: HSS or MTC Server send to mobile management network element or access network elements with described group's page response timer, and described group's page response timer is sent to crowd interior UE to mobile management network element pass-through mode one or access network elements pass-through mode two sends to crowd interior UE with described group's page response timer.
Mode five, mobile management network element carry described group's page response timer in group's paging request message, UE receives described group's paging request message in the group, namely can obtain described group's page response timer.Mobile management network element can obtain described group page response timer or group's page response timer static configuration at mobile management network element from HSS or MTC Server.
S109, mobile management network element for UE in the group who does not respond group's paging request, are initiated each UE that does not respond of paging flow process paging behind group's paging timer expiry;
S110, mobile management network element send group's paging request of group's page-response message response HSS or MTC Server, can be group's page response Group Paging Response or page response Paging Response.
The method of UE response paging in the method for UE and the group in the network side paging group who provides by the present embodiment can greatly reduce the ICQ amount, reduces network resource loss, greatly lower the probability of network congestion and equipment paralysis simultaneously.
Embodiment two
With reference to Fig. 4, the flow process of the present embodiment and embodiment one is basic identical, difference is, replace mobile management network element by access network elements in the present embodiment, obtain alternately subscription data with paging server, directly group's paging request of paging receiving server initiation carries out paging to UE in the group of definite paging range, and idiographic flow comprises:
UE sends registration request in S201, the group, carries UE sign (such as IMSI) in this message.Also portability group identification (such as GroupID or IMSI) is to offer mobile management network element; Described registration request refers to that crowd interior UE carries out the request of registration, comprises Routing Area Update request RAU Request in the location area updating request LAU Request that adheres in the attachment flow in request Attach Request, tracking area request TAU Request, the location area updating flow process or the Routing Area Update flow process.
S202, access network elements obtain subscription data from HSS or MTC Server, and described subscription data can be the subscription data of UE or group's subscription data.Comprise group identification in the subscription data.When access network elements creates context, can comprise group identification and/or UE sign, described group identification can carry to offer access network elements (as described in step S201) or MTC Server or HSS by UE and bring access network elements with group identification.Subscription data request message access network elements is to the message of the subscription data of HSS or MTC Server request UE or group's subscription data, as upgrade position requests Update Location Request or subscription data request Subscriber DataRequest, this message is optionally carried UE sign or group identification.To be HSS or MTC Server send the message of the subscription data of UE or group's subscription data to access network elements to the subscription data response message, as upgrade position response Update Location Response or subscription data response Subscriber Data Response message, this message is optionally carried group identification.In addition, the subscription data response message can also comprise positional information, and described positional information refers to Location Area Identification (perhaps Location Area Identification tabulation), cell ID (perhaps cell identification list), access network elements sign (perhaps access network elements identification list), tracking area identification (perhaps tracking area identification list) or Routing Area Identifier (perhaps Routing Area Identifier tabulation) etc.Access network elements can also be determined the positional information of UE by the residential quarter of UE transmission message in the group, and sends to mobile management network element.So mobile management network element is except obtaining by the user contracting data response message positional information of crowd interior UE, the positional information that access network element obtains in the time of also can accessing by the user is determined the position of crowd interior UE.
