Description

The acquisition methods of machine type communication terminal information and system

Technical field

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

Background technology

In traditional mobile network service, Human To Human (Human To Human, referred to as H2H) communication has occupied main position.In 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.Along with the development of mobile network service and automated control technology, at present, there is a kind of new mobile communication mode, i.e. the communication of machine to machine (Machine To Machine, M2M), in this communication modes, the both sides of communication are machinery equipment.

The M2M definition of narrow sense is the communication of machine to machine, but M2M comprises and take the application that be core, networking of machine terminal intelligent interaction and service in a broad sense.M2M based on intelligent machine terminal, take communication as access means, the informatization resolve scheme that can provide for client, for meeting 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 application (for example, life detection, far-end diagnosis etc.) etc.

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

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

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

In Fig. 1, bottom bearer network comprises: the universal mobile telecommunications system land radio access web of evolution (Evolved Universal Terrestrial Radio Access Network, referred to as E-UTRAN), mobile management unit (Mobility Management Entity, referred to as MME), gateway (Serving Gateway, referred to as S-GW, or SGW), grouped data network gateway (Packet Data Network Gateway, referred to as PDN GW, or P-GW, or PGW), home subscriber server (Home Subscriber Server, referred to as HSS), "Policy and Charging Rules Function entity (Policy and Charging RulesFunction, referred to as PCRF).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 the chain of command such as contextual management in the processing of mobile management, Non-Access Stratum signaling and user's mobile management; S-GW is the accessing gateway equipment being connected with E-UTRAN, forwarding data between E-UTRAN and P-GW, and be responsible for the pending datas such as paging to carry out buffer memory; P-GW is the borde gateway of EPS and packet data network (Packet Data Network, referred to as PDN), is responsible for the access of PDN and the function such as forwarding data between EPS and PDN; PCRF is "Policy and Charging Rules Function entity, it is by receiving interface Rx and carrier network agreement (InternetProtocol, referred to as IP) business network is connected, obtain business information, in addition, it can also be connected with the gateway device in network by Gx interface, be responsible for initiating the foundation of IP carrying, guarantee the service quality (Quality of Service, referred to as QoS) of business datum, and carry out charging control.HSS provides the management of user's subscription data, and user is linked into the management of the important contextual information in network.

In Fig. 1, MTC UE is linked in EPS network by E-UTRAN (eNodeB), after being assigned with IP address, between MTC UE and MTC Server, can set up IP tunnel, thus the upper-layer service communication between realization and MTC Server.The IP tunnel of setting up between MTC UE and 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 M2M communication is on the IP tunnel between MTC UE and MTC Server, to set up an operation layer interface protocol, by this operation layer interface protocol, MTC UE and MTC Server interactive service data, meanwhile, MTC Server also realizes the control to MTC UE by this operation layer agreement.

Fig. 2 describes the flow process that this kind of mode realizes M2M communication, and as shown in Figure 2, in which, MTC UE by PS network insertion, realizes and sets up communication with MTC Server and be connected mainly and comprise the following steps:

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

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

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

S204, if PGW need to be from PCC acquisition strategy data to set up accordingly suitable carrying, PGW and PCC are alternately to obtain PCC strategy;

S205, PGW is that MTC UE creates carrying, returns to load creating response;

S206, MME sends and adheres to response to MTC UE;

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

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

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

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

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

For example, in some high availability M2M communication, MTC server, for the object of intelligent management and real-time monitoring MTC terminal equipment, need to check the situation of MTC terminal equipment access network regularly, normal to confirm the running of MTC terminal equipment.On the other hand, if the abnormal behavior of MTC terminal equipment access network, MTC server needs to understand in time abnormal conditions, to notify in time M2M operation and maintenance personnel to carry out on-site maintenance.Or in the situation that equipment may exist pilferage, MTC server need to have the ability to survey in time possible equipment and be stolen the situation stolen with system, to react in time.

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