Abstract
The invention discloses a machine type communication (MTC) server address acquisition method. The method comprises that: MTC equipment carries an identifier for requesting an MTC server address in an attachment request; and a packet data network gateway (PGW) acquires the MTC server address corresponding to the MTC equipment according to the attachment request, and returns the MTC server address corresponding to the MTC equipment to the MTC equipment. Correspondingly, the invention discloses an MTC server address acquisition system. In the method and the system, the MTC equipment can acquire the corresponding MTC server address by a network request, and the MTC server address is not required to be configured in the MTC equipment in advance; therefore, normal interaction between an MTC server and the MTC equipment can be ensured, and simultaneously, the pre-configuration workload of the MTC equipment can be reduced.
Description
Technical field
(Machine Type Communication, MTC) device assess technology relate in particular to a kind of method and system of the MTC of obtaining server address to the present invention relates to Machine Type communication.
Background technology
Fig. 1 is grouping system (the Evolved Packet System of evolution, EPS) configuration diagram, as shown in Figure 1, third generation partner program (3rd Generation Partnership Project, EPS 3GPP) is by universal mobile telecommunications system land radio access web (the Evolved Universal TerrestrialRadio Access Network of evolution, E-UTRAN), mobile management unit (Mobility Management Entity, MME), gateway (Serving Gateway, S-GW), grouped data network gateway (Packet DataNetwork Gateway, P-GW/PDN GW), home subscriber server (Home Subscriber Server, HSS), "Policy and Charging Rules Function entity (Policy and Charging Rules Function, PCRF), support the GPRS service node (Serving GPRS Supporting Node, SGSN) and other support node form.Wherein, core net partly be called block core evolution (Evolved Packet Core, EPC).
Wherein, 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 that (Packet Data Network, borde gateway PDN) are responsible for the access of PDN and transmit function such as data between EPS and PDN for EPS and packet data network; PCRF is by receiving interface Rx and carrier network agreement (Internet Protocol, IP) business network such as IMS, PSS etc. link to each other, obtain business information, in addition, PCRF can also link to each other with gateway device in the network by the Gx interface, is responsible for initiating the foundation of IP carrying, service quality (the Quality of Service of assurance business datum, and the control of chargeing QoS).SGSN is a core network packet-domain equipment important component part in the UTMS/GSM system, mainly finishes the functions such as routing forwarding, mobile management, session management, Logical Link Management, authentication and encryption, ticket generation and output of packet data package.Whole world terrestrial radio access network (Universal TerrestrialRadio Access Network, UTRAN) and GSM (GPRS)/EDGE Radio Access Network (GSMEDGE Radio Access Network GERAN) can be linked among the EPS by the SGSN accessing gateway equipment.
Fig. 2 is the composition configuration diagram of universal mobile telecommunications system (UTMS), as shown in Figure 2, the UTMS network is made up of UTRAN, SGSN, GGSN (Gateway GPRS Support NodeGGSN), attaching position register (HLR), wherein, SGSN is used to the end packet packet of this SGSN coverage to carry out route and forwarding capability, and terminal is carried out mobile management etc.GGSN provides route and the encapsulation of packet between GPRS net and external data network.(PacketData Network PDN) provides professional for the user in Packet Data Network.HLR is used for storing user subscription data.Use Iu-PS interface to communicate by letter between SGSN and the UTRAN.By Iu-PS interface, SGSN finishes and UTRAN system, communication between terminals, to finish the function of grouped data transmission, mobile management and session management aspect.Finish the functions such as foundation, release and control of IP channel between SGSN and the GGSN by gn interface.SGSN obtains data about terminal by Gr interface from HLR, and HLR preserves GPRS user data and routing iinformation.The Gi interface is the interface between GPRS and the external packet data net.GPRS realizes interconnected by Gi interface and various public's Packet Based Network such as Internet or ISDN net, carry out operations such as the encapsulation/decapsulation, address transition (is publicly-owned net IP address as privately owned net IP address transition) of agreement, authentication when the user inserts and authentication in the Gi interfaces need.
From Fig. 1 and Fig. 2 as can be seen, for the EPS system, mobile management network element is MME, and customer data base is HSS; And concerning the UTMS system, mobile management network element is SGSN, and customer data base is HLR.
What M2M defined narrowly is the communication of machine to machine.Broadly definition is the application and the service of core, networking with the machine terminal intelligent interaction.M2M is based on the intelligence machine terminal, is the access means with multiple communication mode, is the informatization resolve scheme that the client provides, and is used to satisfy the information system requirement of client to aspects such as monitoring, command scheduling, data acquisition and measurements.Data communication between one or more machines is called Machine Type communication, and (Machine Type Communication MTC), lessly in this case needs human-computer interaction.Participate in the machine of MTC, be called MTC equipment.MTC equipment is MTC user's terminal, can communicate by PLMN network and MTC equipment, MTC server.
MTC equipment can be undertaken alternately by PLMN and MTC server, so MTC equipment need be known the address of MTC server in advance, but, because the MTC number of devices is huge, carry out pre-configured more loaded down with trivial details to whole MTC equipment in advance, therefore Virtual network operator do not need to be wished MTC equipment is carried out pre-configured, and MTC equipment can get access to the MTC server address by network.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of method and system of the MTC of obtaining server address, can make MTC equipment under the situation of not pre-configured MTC server address, obtain the MTC server address, guarantee the normal mutual of MTC server and MTC equipment, simplify the pre-configured workload of MTC equipment.
