Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of connection control method and system of machine type communication terminal.
Background technology
M2M (Machine to Machine, machine is to machine) is the concept proposing nineteen nineties, is the important driving force of development communication technologies.Briefly, M2M is exactly the Internet of machine, and the means of realization comprise various networking technologies.The target of M2M technology makes all machinery equipments all possess networking and communication capacity exactly, and its core concept is exactly network all (NetworkEverything).The communication object of M2M is that machine is to machine or 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.The machine that participates in MTC, is defined as MTC terminal (MTC UE, ME).MTC terminal is MTC user's terminal, can communicate with other MTC terminals and MTC server by PLMN (public land mobile network).Fig. 1 is the MTC network configuration under LTE (Long Term Evolution) framework, as shown in Figure 1, MTC UE is by the terminal equipment of carrier network and the communication of MTC server, MTC contractor be one for MTC terminal provides the entity of business, comprise multiple MTC users.MTC user is connected with PLMN network by MTC server, and MTC server provides service for MTC user.
In some application scenarios, MTC terminal only needs to communicate with network within the certain predetermined time period, and the MTC terminal with such feature is called the MTC terminal with " time control " feature.Such as, the MTC terminal in power meter reading system, only in certain default set time section in every month, send data to network side.In the MTC network architecture, MTC terminal is proposed to Group (group) concept, namely MTC terminal has been divided into groups according to common trait or region.If the terminal in MTC grouping has temporal characteristics, so can be for signing same permission section turn-on time of MTC grouping, the terminal in MTC grouping has identical permission section turn-on time like this.
As shown in Figure 2, in the MTC network architecture, for the MTC terminal with " time control " feature, time period information exchange is crossed signing process and is determined, and be kept at as subscription data in the HSS (Home Subscriber Server, home subscriber server) of the home network under terminal.Signing time period information comprises two kinds: permission segment information turn-on time and the time period information of forbidding access.In permission section turn-on time, network side allows MTC terminal to be linked in network, and MTC terminal can be carried out normal business.Forbid access time period in, network side carries out access control to MTC terminal, do not allow MTC terminal to be linked in network, proposition forbids that the demand of the time period of access is because MTC server need to be safeguarded in certain time period, can not carry out normal business, therefore during this period of time network side does not allow the access of MTC terminal.
In the prior art, network side can be revised according to demand and allow segment information turn-on time, such as, the load of machinery systems of network side changes within the different time periods, or have the time difference in different areas, core network element MME (Mobility Manegement Entity, Mobility Management Entity) can allow segment information turn-on time according to the load of machinery systems or some local special circumstances amendments.But, forbid that the time period information of access, once signing, does not allow to modify, even MTC terminal in roam procedure, also will adopt the time period information of forbidding access signing in home network in visited network.
When MTC terminal is during by initial attachment flow access network, core network element MME can obtain from HSS the CAMEL-Subscription-Information of this MTC terminal.Time period information in CAMEL-Subscription-Information can be used as the access control parameter of the MTC terminal with " time control " feature, in the time that the MTC terminal with " time control " feature sends access request message to core net outside signing permission section turn-on time, the access request that core network element will refusal MTC terminal so.Signing time period information can be stored in UICC (Universal Integrated Circuit Card) and be kept in MTC terminal.When MTC terminal roaming is to visited network, the core network element of visited network can, according to permission segment information turn-on time local and on-site time difference of home network or network load situation amendment MTC terminal, can be grouped into granularity with independent MTC terminal or MTC and modify.But after permission segment information turn-on time of the core network element amendment MTC terminal of visited network, MTC terminal cannot know that initiating access request when just can be linked in visited network.
In prior art, MTC terminal cannot get amended permission segment information turn-on time in visited network, what in MTC terminal, retain remains permission segment information turn-on time signing in home network, when MTC terminal cannot get the time period information of this MTC terminal of permission access of visited network, also just cannot be informed in and when initiate access request to be linked in visited network, have significant limitation.
