Description
Technical field
The present invention relates to the communications field, in particular to a kind of method and system of accessing terminal to network.
Background technology
H2H (Human to Human, people is to people) communication refers to interpersonal communication, and people communicates by the operation to equipment, and existing wireless communications technology is that the Communication Development based on H2H is got up.And the sense stricto definition of M2M (Machine to Machine, machine is to machine) is the communication of machine to machine, application and the service that machine terminal intelligent interaction is core, networking take in sensu lato definition.It is based on intelligent machine terminal, take communication as access means, and the informatization resolve scheme providing for client, for meeting 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 space-time restriction and the region obstacle of traditional communication mode, make enterprise and the public break away from cable constraint, allow client more effectively control cost, reduce mounting cost and easy to use.In addition, growing demand driving M2M and is constantly advanced, yet constantly increase with information processing capability and the network bandwidth, be conflictingly, the means of acquisition of information lag far behind, and M2M has well met this demand of people, can Real-Time Monitoring external environment condition by its people, realize on a large scale, the information gathering of automation.Therefore, M2M can be applied to sector application, domestic. applications, individual application etc.Sector application is as traffic monitoring, warning system, rescue at sea, automatic vending machine, driving paying etc.Domestic. applications is as automatic data logging, temperature control etc.Individual application is as life detection, far-end diagnosis etc.
The communication object of M2M be machine to machine, Human-to-Machine.Data communication between one or more machines is defined as MTC (Machine Type Communication, machine type communication), lessly in this case needs human-computer interaction.Participate in the machine of MTC, be defined as MTC equipment (MTC Device, below also referred to as MTC terminal).MTC terminal can be passed through PLMN (Public Land Mobile-communication Network, public land mobile communication network network) network and other MTC terminals or MTC server and communicate.
Introduce after MTC application, can to existing system, carry out some according to its feature and optimize, to meet MTC application demand, and the common UE in existing network (User Equipment, subscriber equipment) is not exerted an influence.Some distinguishing features of M2M application have: MTC terminal quantity is a lot, and the data volume of each transmission is little, and transmission intercal is large, and position is relatively fixing.According to statistics, the MTC terminal of installing in the cell range of one, urban district, London will reach up to ten thousand, if so much more concentrated initiations of MTC terminal access at random, as same alarm in the situations such as fire, earthquake, will to network, bring very large impact.
After introducing MTC application, if a large amount of MTC are connecting system simultaneously, the congested probability of core network signalling improves greatly, once it is congested that core network entity occurs, by refusal user's request, if these users again initiate access within the shorter subsequently time, certainly will cause congestion state to continue can not get to solve.When congestion state starts, if core net access again after can controlling unaccepted user and waiting for the long period is alleviated congestion state and recovery is very helpful.
In current LTE system, at Access Layer, there is corresponding mechanism, when UE configuration UE turn-on time (stand-by period or rollback time) again appears refusing when congested in Access Network, be 16 seconds to the maximum.
Core network entity (MME) is if there is congested, can send overload and start signaling Overload Start to base station eNB, as shown in Figure 1, wherein comprise the actions such as Reject all RRC connection establishments for non-emergency MODT, Reject all RRC connection establishments for Signalling, Permit Emergency Sessionsand mobile terminated services only, require eNB no longer to transmit corresponding service type requests to MME; In these signalings, core net does not configure the applicable retry time (how long allowing afterwards service request), the continuous retry of user during that is to say, until core network entity recovers normally, (MME sends overload and finishes signaling Overload Stop message to eNB, represent that core net recovery is normal, as shown in Figure 2).
After introducing MTC application, if a large amount of MTC terminals are connecting system simultaneously, the congested probability of core network signalling improves greatly, once it is congested that core network entity occurs, by the request of the current all MTC terminals of refusal, if these MTC terminals are initiated access again subsequently simultaneously, certainly will cause congestion state to continue can not get to solve.
In current LTE system, at Access Layer, have corresponding mechanism, but the UE that can configure is 16 seconds again turn-on time to the maximum, under congested serious situation, is not enough to alleviate congestion.
For core network entity in correlation technique, occur congested, by the request of the current all MTC terminals of refusal, if these MTC terminals are initiated access again subsequently simultaneously, certainly will cause congestion state to continue can not get the problem of solution, effective solution is not yet proposed at present.
