Description
Technical field
The present invention relates to moving communicating field, relate in particular to a kind of Machine Type communication (MTC, Machine Type Communication) server triggers MTC equipment and initiate communication and obtain the method and system of the IP address of MTC equipment.
Background technology
Along with global microwave access intercommunication (WiMax; World Interoperability for Microwave Access) sudden emergence of technology; 3-G (Generation Three mobile communication system) will keep its competitiveness at moving communicating field; Its network performance be must improve, and networking and operation cost reduced.Therefore at present; Third generation partner program (3GPP; 3rd Generation Partnership Project) standardization effort group just is being devoted to research to packet switched core network (PS Core; Packet Switched Core) and global system for mobile communications wireless access network (UTRAN; Universal Mobile Telecommunication System Radio Access Network) evolution; Purpose is the PS Core that makes evolution; Also can be described as the UTRAN (E-UTRAN that EPC can provide higher transmission rate, shorter transmission delay and support evolution; Evolved UTRAN), the mobile management between the access network of global system for mobile communications enhanced data rates global system for mobile communications evolution technology wireless access network (GERAN, Global System for Mobile communications Enhanced Data Rate for GSM Evolution radio access network), UTRAN, WLAN (WLAN, Wireless Local Area Network) and other non-3GPP.The GSM of this evolution just is called as the grouping domain system (EPS, Evolved Packet System) of evolution.Fig. 1 is the framework map of above-mentioned EPS system, only shows the part entity relevant with the present invention among Fig. 1.Following to each entity declaration among Fig. 1:
Travelling carriage (MS, Mobile Station)/subscriber equipment (UE, User Equipment) 101 has the ability of ability access of radio network.Wherein, MS also can be called portable terminal.
GERAN/UTRAN 102, the wireless access network of traditional GSM/UMTS network.
GPRS serving GPRS support node (SGSN; Serving GPRS Support Node) 103; Be the control network element of GPRS (GPRS, General Packet Radio Service) network, main effect is the positional information of record UE; And between UE and GGSN (GGSN, Gateway GPRS Supporting Node), accomplish the transmission and the reception of mobile packet data.
Gateway (S-GW, Serving Gateway) 104 is user entities, is responsible for the user face data route and handles, and termination is in the downlink data of the UE of free time (ECM_IDLE) state.The SAE of management and storage UE carries (bearer) context, such as IP bearer service parameter and network internal routing iinformation etc.S-GW is the anchor point of 3GPP internal system user plane, and a user can only have a S-GW a moment.
Packet data network gateway (P-GW or PDN GW; Packet Data Network Gateway) 105, be to be responsible for the gateway that UE inserts PDN, distributing user IP address; Also be the mobility anchor point of 3GPP and non-3GPP connecting system, the function of P-GW comprises that also strategy is implemented, charging is supported.The user can insert a plurality of P-GW at synchronization.Strategy also is arranged in P-GW with the enforcement functional entity (PCEF, Policy and Charging Enforcement Function) that charges.
P-GW and S-GW can be located in the physical entity, and be as shown in Figure 1, also can be respectively in different physical entities.
GGSN106, the edge routing function of support GPRS network, promptly GGSN is responsible for the data of GPRS network are carried out routing forwarding, and protects the integrality of GPRS network data through fire compartment wall and filtering function.GGSN also has billing function.
P-GW has comprised the repertoire of GGSN, can think that GGSN as the sub-function of P-GW, is embedded in the P-GW.Therefore SGSN can directly be connected with P-GW, uses the Gn/Gp interface.Home subscriber server (HSS)/attaching position register (HLR) 107 is to support to call/the main users database of session.
UE needs network when the use of communicating by letter with network foundation is professional be its distributing IP address, and network can be UE distributing IP v4 address, also can be UE distributing IP v6 prefix.EPS network for R8 and later release; Packet data protocol (PDP) context or an EPS carry and support to use IPv4 address and IPv6 address simultaneously; So for the UE that supports two stacks (dual stack), can be to network application distributing IP v4 address, IPv6 prefix or IPv4 address and IPv6 prefix.
When UE inserts the EPC network through E-UTRAN; The default bearing that the IP address assignment of UE can connect flow process through the PDN of attachment flow or UE request carries out when activating: ownership Public Land Mobile Network (HPLMN) can be that UE distributes static IP address; Serve (Radius like configuration on HSS or in that agreement (Dynamic Host Configuration Protocol)/far-end authentication dial-in customer is set based on the external dynamic main frame; Remote Authentication Dial In User Service)/upgraded version (Diameter) server of Radius agreement on based on user and APN granularity (per-user per-APN) configuration; Or HPLMN can distribute dynamic IP address for UE, as on P-GW, distributing; The Public Land Mobile Network (VPLMN) of being interviewed can distribute dynamic IP address for UE, disposes like the P-GW at VPLMN; PDN operator or administrator can also be that UE distributes dynamic or static IP address through other address servers such as outside DHCP Server or AAA Server.After if above-mentioned flow process finishes, UE is unallocated to the IP address, and then follow-up UE can pass through the IP address assignment mechanism of the Internet engineering duty group (IETF, Internet Engineering Task Force) definition and carry out address assignment.
When UE inserted 3G network through GERAN/UTRAN, the IP address assignment mechanism of UE and EPS network class seemingly just repeated no more here.
The sense stricto definition of M2M is the communication of machine to machine.Sensu lato definition is the application and the service of core, networking with the machine terminal intelligent interaction.It 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.
The development of wireless technology is the key factor of M2M market development; It has broken through the space-time restriction and the region obstacle of traditional communication mode; Make the enterprise and the public break away from the cable constraint, let the client more effectively control cost, reduce mounting cost and easy to use.In addition, growing demand is promoting M2M and constantly advancing: constantly increasing conflicting with the information processing capability and the network bandwidth is that the means that information is obtained lag far behind.And fine this demand that has satisfied people of M2M can be monitored external environment condition in real time through its people, realizes on a large scale, the information gathering of automation.Therefore, M2M can be applied to sector application, domestic. applications, individual's application etc.Sector application is like traffic monitoring, warning system, rescue at sea, automatic vending machine, driving paying etc.Domestic. applications is like automatic data logging, temperature control etc.The individual use as: life detection, far-end diagnosis etc.
The communication object of M2M is a machine, the Human-to-Machine.Data communication between one or more machines is defined as MTC, lessly in this case needs human-computer interaction.Participate in the machine of MTC, be defined as MTC equipment.MTC equipment is MTC user's terminal, can communicate through PLMN network and MTC equipment, MTC server.MTC server (MTC Server) is managed and is monitored MTC equipment.Fig. 2 is that MTC UE is through the sketch map of E-UTRAN access EPS system in the prior art, and Fig. 3 is the sketch map that MTC UE inserts the 3G system in the prior art through UTRAN/GERAN.
In addition; The requirement of access control flexibly when the MTC terminal being linked into network in order to satisfy; Be reduced to caused complicacy transformation to core net when supporting this type access limit service simultaneously, it is also conceivable that following two kinds of network architectures: a framework is as shown in Figure 4 as far as possible, and operator can be used as the service provider provides MTC professional; Therefore MTC Server can be that operator disposes and management; Perhaps provide the professional third party of MTC believable, in this case, can consider to set up between MTC Server and the HLR interface for operator; Another framework is as shown in Figure 5; MTC Server possibly not be the network entity of operator's management; And might be deployed in outside the core net; Therefore, the access security when relating to MTC Server and being linked into core net, can consider increases MTC gateway (MTC GW) in core-network side; Make the access of all MTCServer all through this MTC gateway, this MTC gateway can hide through the internal network topological structure, MTC Server is inserted means such as carrying out authentication realizes that MTC Server is linked into the safety assurance of core net.And; In above-mentioned two kinds of frameworks; All increase MTC Server or newly-increased MTC gateway and the interface between the mobile management network element SGSN; Pass through the information that mobile management network element SGSN obtains the bottom Access Layer at this MTC terminal by operation layer (MTC Server or newly-increased MTC gateway), and then the access at this MTC terminal is controlled according to the MTC terminal information of obtaining.
In MTC uses; Having some scenes to need MTC Server to trigger MTC equipment initiates to carry out the transmission of data with communicating by letter of MTCServer; As: in some supervision and reporting classes are used; Except being set, MTC equipment regularly reports the monitoring report to MTC Server; MTC Server also can ask MTC equipment to carry out reporting of measurement data aperiodically, in this case, just needs MTC Server to send to indicate triggering MTC equipment to be connected to network or set up the data connection to MTC equipment and communicates with MTC Server.In these were used, MTC equipment can be in off-line state for network, also can be in line states, comprising: idle condition and connection status.Wherein, for connection status, no matter be at the EPS network or in 3G network, the user plane passage of UE is that foundation is got well and UE has been assigned with the IP address, and the IP packet of UE can transmit in the user plane passage; For idle condition, in the EPS network, the UE of Idle state has been assigned with the IP address.And in 3G network, the UE of Idle state is not assigned with the IP address.Be in the situation of line states for MTC equipment,, then can the trigger data bag be sent to network, find and triggered MTC equipment by the corresponding mechanism of network using if MTC Server knows the IP address of MTC Device.
When UE inserts the EPC network through E-UTRAN, when UE initially is attached to network, will set up default bearing and in this process, be assigned to the IP address, before the UE attachment removal, all supply this UE to use.In this case; If require MTC Server can trigger MTC equipment; Then can be telling Server to MTC for the dynamic IP addressing of MTC devices allocation, concrete grammar can be: after MTC equipment obtains the IP address, give MTC Server with this IP address notification alternately through application layer.
And when UE inserted 3G network through GERAN/UTRAN, UE can't be assigned with the IP address when adhering to, but obtained the IP address through subsequent P DP context active flow.Be attached to network but when not having the UE of PDP Context, network need be initiated the PDP context activation flow process of network requests and need seek when network.According to prior art; The PDP context activation flow process of network requests is only supported the static ip address situation of UE; That is: the IP address of UE is a static configuration in advance; And GGSN need know the international mobile subscriber identity (IMSI, International Mobile Subscriber Identification Number) of UE and the pair relationhip of static ip address.As shown in Figure 6, may further comprise the steps:
Step 601:GGSN receives PDP PDU packet and confirms to need to initiate the PDP context activation flow process of network requests.
Step 602:GGSN sends " sending the GPRS routing iinformation " message according to the pair relationhip of the IMSI of static ip address inquiry itself and this UE of the UE that carries among the PDP PDU to HLR, wherein carries the IMSI of UE.
Step 603:HLR inquires the IP address of the SGSN that UE registers according to the IMSI of UE, and returns " sending the response of GPRS routing iinformation " message, the IP address of wherein carrying the SGSN that IMSI and UE registered of UE.
Step 604:GGSN sends " Packet Data Unit notice request " message to SGSN, carries IMSI and the APN (APN, Access Point Name) of UE, and request SGSN initiates the PDP context activation flow process of network requests.
Step 605:SGSN returns " Packet Data Unit push-notification-answer " message to GGSN.
" the PDP context activation request information is wherein carried APN to step 606:SGSN, requires UE to initiate the PDP context activation flow process according to the APN of appointment to the UE transmission.
Step 607:UE initiates the PDP Context process and is UE distributing IP address by network.
In sum; MTC Server triggers the scene that the initiation of MTC equipment is communicated by letter with MTC Server; Prerequisite is to know that the IP address of MTC equipment is just feasible, and to the MTC equipment that inserts 3G network through GERAN/UTRAN, is to obtain the IP address through subsequent P DP context active flow; And according to present prior art, the PDP context activation flow process is only supported the static ip address of UE.The IPv6 address is not widely used because the IPv4 address resource is very limited, therefore considers that to address resources effective utilization dynamic assignment IP address can be bigger than static configuration IP address advantage in practical application.And static ip address needs extra configuration for network, and is restricted bigger, also few in practical application.Yet; Scene in that MT reconnaissance C Server triggering MTC equipment initiates to communicate by letter with MTC Server takes dynamic assignment IP address also infeasible at present, that is to say, in the prior art; When MTC equipment is not assigned with dynamic IP addressing through GERAN/UTRAN access 3G network; MTC Server is the IP address that can't know MTC equipment, therefore also can't find MTC equipment through network, initiates and the communicating by letter of MTC Server thereby MTCServer can't trigger MTC equipment.
In addition; Consider mobile subscriber's international number (MSISDN; Mobile Subscriber International ISDN/PSTN Number) be mainly used in voice communication and short message communication, therefore, for the MTC equipment that is in line states; If MTC equipment has been assigned with Mobile Subscriber International ISDN Number, then can also triggers MTC equipment through the mode of short message and initiate and the communicating by letter of MTC server.But because the MTC amount of equipment is huge, if each MTC devices allocation Mobile Subscriber International ISDN Number certainly will cause the shortage of Mobile Subscriber International ISDN Number resource.And it be that data are used and non-voice service that most from now on MTC uses, and therefore maybe not can be assigned with Mobile Subscriber International ISDN Number, therefore also can't use mode through short message to trigger MTC equipment and initiate and the communicating by letter of MTC Server.
