Description

The acquisition methods and the system of machine class communicating terminal information

Technical field

The present invention relates to the communications field, in particular to the acquisition methods and the system of a kind of machine class communication (Machine Type Communication abbreviates MTC as) end message.

Background technology

In traditional mobile network's service, Human To Human's (Human To Human abbreviates H2H as) communication has occupied main position.In the H2H communication, because the both sides that participate in are the people with behavior control ability, so in fact session is controlled by people's behavior.Development along with mobile network's service and automated control technology at present, a kind of new mobile communication mode occurred, and promptly (in this communication modes, the both sides of communication are machinery equipment to machine for Machine To Machine, communication M2M) to machine.

The M2M definition of narrow sense is the communication of machine to machine, but M2M comprises that with the machine terminal intelligent interaction be application and service core, networking in a broad sense.M2M is the access means based on the intelligence machine terminal, with multiple communication mode, and the informatization resolve scheme that can provide for the client is used to satisfy the information system requirement of client to aspects such as monitoring, command scheduling, data acquisition and measurements.M2M (for example can be applied to sector application, traffic monitoring, warning system, rescue at sea, automatic vending machine, driving paying etc.), domestic. applications (for example, automatic data logging, temperature control etc.) and individual's application (for example, life detection, far-end diagnosis etc.) etc.

With the most basic different being of Human To Human's communication, the communication object of M2M is a machine, and the communication behavior is automation control, i.e. some accesses in the initiation of communication, the termination of communication, the communication process and the control of restriction all are behaviors of automation.This behavior depends in the M2M communication machine (being the terminal in the M2M communication) covenant of works bundle and control, and the behavior of the terminal in the M2M communication is subjected to the service contracting data constraint, and network based service contracting data manage the terminal in the M2M communication.

The M2M communication, be also referred to as machine class communication (Machine Type Communication, abbreviate MTC as), most typical is communication between terminal and the application server, this terminal is called as MTC terminal (MTC User Equipment, abbreviate MTC UE as), application server is called as MTC server (MTC Server).

Under 2G/3G/LTE inserts, the M2M communication mainly with grouping (Packet Service abbreviates PS as) network as the bottom bearer network, realize the operation layer communication between MTC terminal and the MTC server.Fig. 1 is the configuration diagram of the M2M communication entity grouping system (Evolved Packet System abbreviates EPS as) that is linked into evolution.

In Fig. 1, the bottom bearer network comprises: the universal mobile telecommunications system land radio access web of evolution (Evolved Universal Terrestrial Radio Access Network, abbreviate E-UTRAN as), mobile management unit (Mobility Management Entity, abbreviate MME as), gateway (Serving Gateway, abbreviate S-GW as, or SGW), grouped data network gateway (Packet Data Network Gateway, abbreviate PDN GW as, or P-GW, or PGW), home subscriber server (Home Subscriber Server, abbreviate HSS as), "Policy and Charging Rules Function entity (Policy and Charging Rules Function abbreviates PCRF as).Wherein, the main network element of E-UTRAN is eNodeB (Evolved NodeB base station).

In Fig. 1, MME is responsible for the related work of chain of command such as contextual management in the processing of mobile management, Non-Access Stratum signaling and the user's mobile management; S-GW is the accessing gateway equipment that links to each other with E-UTRAN, transmits data between E-UTRAN and P-GW, and is responsible for pending datas such as paging are carried out buffer memory; P-GW then is the borde gateway of EPS and packet data network (Packet Data Network abbreviates PDN as), and the access of being responsible for PDN reaches functions such as transmitting data between EPS and PDN; PCRF is the "Policy and Charging Rules Function entity, it is by receiving interface Rx and carrier network agreement (Internet Protocol, abbreviating IP as) business network links to each other, obtain business information, in addition, it can also link to each other with gateway device in the network by the Gx interface, be responsible for initiating the foundation of IP carrying, guarantee the service quality (Quality of Service abbreviates QoS as) of business datum, and the control of chargeing.HSS provides user's management of subscription data and the management that the user is linked into the important contextual information in the network.

In Fig. 1, MTC UE is linked in the EPS network by E-UTRAN (eNodeB), after being assigned with the IP address, can set up IP tunnel between MTC UE and the MTC Server, thus the upper-layer service communication between realization and the MTC Server.The IP tunnel of being set up between MTC UE and the MTC Server is an IP tunnel in logic, its physical pathway process: eNodeB, S-GW, P-GW.

At present, a kind of mode that realizes the M2M communication is to set up an operation layer interface protocol on the IP tunnel between MTC UE and the MTC Server, by this operation layer interface protocol, MTC UE and MTC Server interactive service data, simultaneously, MTC Server is also by the control of this operation layer agreement realization to MTC UE.

Fig. 2 describes the flow process that this kind mode realizes the M2M communication, and as shown in Figure 2, MTC UE realizes that setting up communication with MTC Server is connected mainly and may further comprise the steps by the PS network insertion in this mode:

S201, MTC UE initiates to adhere to request to MME;

S202, MME receive the above-mentioned request of adhering to, and send position updating request to HSS, and in this step, HSS wherein comprises the subscription data part that is used for the M2M access control to the subscription data that MME downloads MTC UE;

S203, MME sends the load creating request to SGW/PGW, and request SGW/PGW creates suitable carrying for MTC UE;

S204, if PGW need be from PCC acquisition strategy data to set up suitable carrying in view of the above, PGW and PCC are alternately to obtain the PCC strategy;

S205, PGW return the load creating response for MTC UE creates carrying;

S206, MME send to MTC UE and adhere to response;

Behind the step S026, MTC UE has been attached to the PS network, has been assigned with the IP address, and foundation and suitable carrying, thereby can initiate the registration of operation layer to MTC Server.

S207, MTC UE initiate the registration of operation layer to MTC Server;

S208, MTC Server accepts the registration of MTC UE, returns the registration response;

S209 passes through operation layer protocol interaction data between follow-up MTC UE and the MTC Server.

By flow process shown in Figure 2, MTC UE is linked into the PS network, set up and MTC Server between IP connect, thereby can realize operation layer communication between follow-up and the MTC Server.In this flow process, since between MTC Server and the bottom Access Layer (referring to network elements such as MME/SGW/PGW) without any contact, therefore, MTC Server can't obtain the event of bottom Access Layer, thereby can't judge whether the behavior of MTC UE is normal according to these incidents, need operation layer to possess the M2M business (as high availability M2M communication, have the M2M communication of intelligent management ability etc.) of higher control for some, adopt above-mentioned access way to realize.

For example, in some high availability M2M communication, the MTC server needs check the situation of MTC terminal equipment access network, to confirm the running of MTC terminal equipment normally for the purpose of intelligent management and real-time monitoring MTC terminal equipment regularly.On the other hand, if the abnormal behavior of MTC terminal equipment access network, then the MTC server needs in time to understand abnormal conditions, carries out on-site maintenance with timely notice M2M operation maintenance personnel.Perhaps, may exist at equipment under the situation of pilferage, the MTC server needs the possible equipment of the timely detection of ability and is stolen the situation stolen with system, so that react in time.

Especially intelligent management and in real time monitoring requirement than higher M2M communication in, for the MTC server, in order to satisfy higher management expectancy, the MTC server may need to know in time the situation of MTC terminal equipment access network, typically, the MTC server may need to obtain the following information with the MTC terminal:

(A) regularly insert monitoring: to some business, need the time that is linked into network of restriction MTC terminal equipment, if non-permission time access network takes place, then the MTC server needs in time to obtain this situation;

(B) restriction is inserted in the zone: to some business, need restriction MTC terminal equipment from where the zone is linked into network, if take place to be linked into network from the unallowed band of position, then the MTC server needs in time to obtain this situation;

(C) mobility restriction: to some business, only allow the MTC interrupting device to move surely in predefined zone, perhaps do not allow the MTC terminal equipment to be moved continually, if above-mentioned these unallowed mobility behaviors take place, then the MTC server needs in time to obtain this situation;

(D) SIM usurps inspection: because the rate of M2M communication may be lower than common mobile communication rate, if the SIM card of MTC terminal equipment is stolen, will bring loss to service provider.In order to take precautions against the generation of this class situation, service provider may require international member identification code (the International Mobile SubscriberIdentification Number in the SIM card, abbreviate IMSI as) and international mobile equipment identification number (the International Mobile Equipment Identity of MTC terminal equipment, abbreviate IMEI as) bind, promptly an IMSI can only be used by some MTC terminal equipments with specific IMEI.In this case, the MTC server need be verified the IMSI and the IMEI binding of MTC terminal.

To above-mentioned these business demands, the relevant information of MTC terminal all has only the Access Layer/bearing bed of bottom to obtain, and has only MME can obtain necessary information under E-UTRAN inserts and is also judged.From having the framework that M2M communication (referring to the communication between MTC UE and the MTC Server herein) is linked into EPS now, the MTC server can't be known above-mentioned these information, thereby has influenced intelligent management, the realization of monitoring service in real time.

According to the embodiment of the invention, a kind of acquisition methods of MTC UE information also is provided, this method can realize by the said system that provides according to the embodiment of the invention.

Acquisition methods according to the MTC UE information of the embodiment of the invention comprises: the MTC server by and mobile management network element between interface, the request of obtaining is attached to network or has been attached to the MTC terminal information of network.

Particularly, as shown in Figure 6, MTC Server obtains the information spinner that current request is attached to network or has been attached to the MTC UE of network will may further comprise the steps (step S601-step S603):

Step S601: mobile management network element reports the MTC terminal information to the MTC server;

Step S603:MTC server obtains the MTC terminal information that mobile management network element reports.

In specific implementation process, mobile management network element reports the MTC terminal information to include but not limited to following three kinds of methods to the MTC server:

(1) mobile management network element initiatively reports to MTC Server

Particularly, when mobile management network element can take place in Access Layer/bearing bed incident of certain MTC UE, proactive notification MTC Server, perhaps, mobile management network element initiatively reports the information of certain MTC UE to MTC Server.

(2) MTC Server inquires about to mobile management network element

MTC Server after mobile management network element receives the query requests of MTC Server, reports the information of pairing MTC UE to the information of mobile management network element inquiry MTC UE to MTC Server.

(3) MTC Server subscribes to the dependent event notice of MTC UE to mobile management network element

MTC Server subscribes to the Access Layer/bearing bed incident relevant with a certain MTC UE to mobile management network element, when mobile management network element takes place in the Access Layer of subscribing to/bearing bed incident, proactive notification MTC Server includes the information of corresponding MTC UE in the notice.

Respectively the above-mentioned three kinds methods of obtaining MTC UE information are described below.Need to prove that above-mentioned three kinds of methods can separately be used, also can be in twos or triplicity use.

(1) mobile management network element initiatively reports to MTC Server

Particularly, initiatively when MTC Server reported the information of MTC UE, mobile management network element was according to the indication of carrying from this MTC UE that the user contracting data memory obtains to mobile management network element, initiatively reported the information of MTC UE to MTC Server.Particularly, the mobile management network element subscription data that obtains this MTC UE from the user contracting data memory comprises: the indication mobile management network element to MTC Server report MTC UE indication information (specifically can indicate information such as comprising the opportunity that reports, the parameter that reports), be the information of the MTC Server of this MTC UE service.Mobile management network element can be resolved the address that obtains to the MTC Server of this MTC UE service from the information of the MTC Server that obtains, thereby the information of this MTC UE is reported MTC Server.

In specific implementation process, mobile management network element can initiatively report the information of this MTC UE to MTC Server when MTC UE initiates to adhere to request, also can be after MTC UE be attached to network, when the Access Layer relevant with this MTC UE/bearing bed incident takes place, initiatively, in event notice, carry the current information of MTC UE to MTC Server reported event notice.

Be that MME is an example below with the mobile management network element, report describe opportunity at these two kinds to the flow process that MTC Server reports to MME.

(1) when MTC UE initiates to adhere to request, MME initiatively reports the information of MTC UE to MTC Server

Fig. 7 is in this case, and MME initiatively reports the flow chart of the information of MTC UE to MTC Server, and as shown in Figure 7, when MTC UE initiated to adhere to request, MME initiatively reported the information spinner of MTC UE may further comprise the steps to MTC Server:

S701, MTC UE initiates to adhere to request to MME;

S702, MME sends position updating request to HSS;

S703, HSS upgrades response to the MME home position, upgrade the subscription data that response carries MTC UE in this position, comprise in this subscription data: indication MME to MTC Server report the information of this MTC UE indication information, for the information of the MTC Server of this MTC UE service (particularly, this information can be the address of MTC Server, also can be the information such as sign of MTC Server);

S704, MME go out the address of this MTC Server according to the information analysis of the MTC Server that serves for this MTC UE;

The address of the MTC Server that S705, MME obtain according to parsing reports the information of MT reconnaissance C UE to this MTC Server.

(2) after MTC UE is attached to network, MME initiatively reports the information of MTC UE to MTC Server

Fig. 8 is in this case, and MME initiatively reports the flow chart of the information of MTC UE to MTC Server, and as shown in Figure 8, after MTC UE was attached to network, MME initiatively reported the information spinner of MTC UE may further comprise the steps to MTC Server:

S801, MTC UE is attached to the PS network;

Be attached in the process of PS network at MTC UE, MME has obtained the subscription data of MTC UE from HSS, comprising the subscription data that is used for the M2M service part.In these M2M service contracting data, be included as the address of the MTC Server of this MTC UE service, request MME initiatively reports indication from the scheduled event relevant with this MTC UE to MTC Server, promptly ask MME when scheduled event takes place this MTC UE, send event notice to MTC Server;

Wherein, above-mentioned scheduled event is the Access Layer/bearing bed incident relevant with this MTC UE, and particularly, above-mentioned scheduled event includes but not limited to one of following or its combination in any:

(1) subscription data of MTC UE changes; Behind the subscription data of HSS change MTC UE, HSS need issue new subscription data again to MME, after MME receives new subscription data, can notify this subscription data of MTC Server to change or directly new subscription data is sent to MTC Server;

(2) state variation of MTC UE; For example, MTC UE be attached to network, MTC UE from network attachment removal, MTC UE by connected state change to Idle state, MTC UE changes to connected state by Idle state;

(3) variation of the band of position of MTC UE; For example, MTC UE has taken place that the position is moved etc., and when MTC UE occurrence positions moved, MTC UE can send location update message to MME, the position has taken place moves thereby make MME can capture MTC UE;

(4) network change of MTC UE; For example, the switching of base station, network has taken place in MTC UE, and in this case, MTC UE can send to MME and switch message, thereby makes MME can capture the network change incident that MTC takes place.

S802, above-mentioned scheduled event, promptly relevant with MTC UE Access Layer/bearing bed incident takes place;

S803, MME initiatively notify the generation of this scheduled event to MTC Server, particularly, MME includes the current information of MTC UE in the event notice that MTC Server sends.

It is pointed out that in flow process shown in Figure 8 the Access Layer of S802/bearing bed incident may occur among the step S801, for example, this incident is one and adheres to incident that then MME should send event notice to MTC Server when MTC UE is attached to network.

Particularly, in the flow process of above-mentioned Fig. 7 and Fig. 8, the information of the MTC UE that MME reports to MTC Server includes but not limited to one of following or its combination in any:

A) MME is from the MTC UE current business subscription data of HSS acquisition;

B) the employed IMSI of MTC UE, IMEI; Wherein, the employed IMSI of MTC carries adhering in the message of sending when being attached to network of MTC UE, IMEI then may be MTC UE when adhering to by offering network, also may be obtaining of network based needs to MTC UE inquiry;

C) contextual information of MTC UE on MME, for example, the current location zone of MTC UE, the current state of MTC UE;

Wherein, the current location zone of MTC UE can be: the tracing area of MTC UE (Tracking Area, abbreviate TA as), the current Cell sub-district of MTC UE, and the current state of MTC UE may be a kind of in attachment state, attachment removal state, connection status, the idle condition etc.

D) the current mobility event that takes place of this MTC UE, for example, MTC UE is attached to network, MTC UE from network attachment removal, the renewal of MTC UE position, MTC UE base station switching, the switching of MTC UE generation network etc. takes place.

(2) MTC Server inquires about to mobile management network element

Particularly, after MTC UE was attached to network, MTC Server sent query requests to mobile management network element, the information of this MTC UE of request inquiry, and mobile management network element reports the information of this MTC UE to MTC Server after receiving this query requests.

In specific implementation process, at MTC Server before mobile management network element sends query requests, MTC Server at first needs to be retrieved as the address of the mobile management network element that MTC UE distributes, according to this address, send above-mentioned query requests then to the mobile management network element that distributes for this MTC UE.

In specific implementation process, the address that MTC Server is retrieved as the mobile management network element of MTC UE distribution includes but not limited to following three kinds of methods:

(1) MTC Server obtains the identification information that carries the mobile management network element that promising this MTC UE distributes in the registration message that MTC UE sends;

For example, in the EPS network, MTC UE can carry global unique temporary identity (the Global Unique Temporary Identity of network for this MTC UE in the registration message that sends to MTC Server, abbreviate GUTI as), and comprise the id information of the MME that promising MTC UE distributes among the GUTI, by resolving GUTI, MTC Server can be retrieved as the address of the mobile management network element of this MTC UE distribution;

(2) mobile management network element that distributes for MTC UE is initiatively notified its address to MTC Server;

(3) MTC Server by its with the user contracting data memory between interface, be retrieved as the address of the mobile management network element of MTC UE distribution from the user contracting data memory.

Be example with the E-UTRAN network below, the acquisition methods of the address of above-mentioned three kinds of mobile management network elements is described.

(1) from the registration message that MTC UE sends, resolves and obtain

Fig. 9 is the flow chart of the address of the MME that MTC Server is retrieved as this MTC UE distribution in concrete the application by the GUTI that resolves MTC UE, as shown in Figure 9, MTC Server mainly may further comprise the steps by the address that the GUTI that resolves MTC UE is retrieved as the MME of this MTC UE distribution:

S901, MTC UE is attached to the PS network, and network has distributed a GUTI for MTC UE in attaching process, and this GUTI is carried to adhere to and sends to MTC UE in the response;

Formation by resolving GUTI comprises the id information of the MME that promising MTC UE distributes as can be known among the GUTI, according to this MME ID, MTC Server can be addressed to the MME that distributes into this MTC UE.

S902, MTC UE are after being linked into the PS network, and the registration message to MTC Server initiates the application layer registration wherein, carries above-mentioned GUTI information in this registration message;

S903, MTC Server be according to the GUTI information of carrying in the registration message, resolve the address of the MME that distributes for MTC UE, the address of the MME that obtains according to parsing, MTC Server can send query requests to this MME, to inquire about the information of this MTC UE under the situation of needs;

S904, if having interface between MTC Server and the HSS, then MTC Server is to the subscription data of HSS inquiry MTC UE.

S905 allows MTC UE registration if MTC Server judges according to business datum, then returns the registration response.In this registration response, may carry some operation layer parameters and give MTC UE.

(2) MME that distributes for MTC UE initiatively notifies its address to MTC Server
