Description
Technical field
The present invention relates to the communications field, particularly relate to a kind of MTC (MachineTypeCommunication, machine type communication) acquisition methods of block terminal paging DRX (DiscontinuousReception, discontinuous reception) cycle parameter under the network architecture and device.
Background technology
M2M (MachinetoMachine, machine-to-machine communication) is the concept that last century, the nineties proposed, and is the important driving force of development communication technologies.Briefly, M2M is exactly the Internet of machine, it is achieved means include the technology of various networking.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 Machine To Machine or Human-to-Machine.Data communication between one or more machines is defined as MTC, in this case less need for human-computer interaction.Participate in the machine of MTC, be defined as MTC device (MTCdeivce).MTC device is the terminal of MTC user, can be communicated by public land mobile communication network (PLMN) and MTC device, MTC server.Fig. 1 is the MTC network structure under Long Term Evolution (LTE) framework, MTC device (MTCEquipment) is the terminal unit by carrier network and MTC server communication, MTC contractor is an entity providing business for MTC terminal, including multiple MTC users.MTC user is connected with PLMN network by MTC server, and MTC server provides service for MTC user.
In existing mobile communication technology, H2H (HumantoHuman, Human To Human communicates) mobile terminal may be at two states at Access Layer: RRC Idle state (RRC-IDLE) and RRC connected state (RRC-CONNECTED).The mobile terminal being in Idle state realizes the function of following two aspects: can monitor the beep-page message of its persistent district on the one hand, and carry out the renewal (namely re-reading cell system message) of cell system message according to the instruction of beep-page message, or initiate and the connection of network side is to proceed to RRC connected state；On the other hand, it is possible to periodically or triggered by event, mobile terminal is initiated and the location area updating process of network side, to indicate the band of position at its place of network equipment.After network side learns the band of position at terminal place, needs to this move equipment carry out paging time, community in the corresponding band of position sends beep-page message.
At LTE/UMTS (UniversalMobileTelecommunicationsSystem, UMTS) in the network architecture, when terminal is in Idle state, if there being downlink data to need terminal to receive, network side can send beep-page message to terminal, wakes terminal downlink data receiving up.As shown in Figure 2, paging is divided into what two steps carried out, first when gateway (SGW)/GPRS service node (SGSN) can not find, after receiving downlink data, the terminal that can receive data, being notified that core network element Mobility Management Entity (MME)/SGSN, core network element can pass through and the interface (S1/Iu) of Access Network side sends beep-page message.Base station parses the paging domain and paging DRX cycle information that carry in this interface paging message after receiving beep-page message, then pass through the beep-page message sending Uu interface and carry out call terminal.Single terminal is all carried out by these flow processs above-mentioned.The paging employing DRX reception technique in H2HUE paging flow process, in order to save terminal power consumption amount, to terminal in the prior art.Terminal receives beep-page message in certain paging occasion (referring to certain radio frames and wireless sub-frame), evolution UMTS Terrestrial radio access network (E-UTRAN) configure those radio frames and subframe for paging.The position of concrete paging frame and paging subframe can be calculated by paging DRX cycle parameter.Base station is at the paging DRX cycle of each its acquiescence of Cell Broadcast CB.Additionally, core net is likely to configure the specific paging cycle of UE with dedicated signaling.If both configured, UE adopts minima.UE is by calculating paging occasion.
MTC terminal is proposed packet (Group) concept by the MTC network architecture.Namely MTC terminal is grouped according to common trait or region.In some MTC application scenarios, some downlink datas are desirable in MTCGroup all MTC terminal and receive.Such as MTCSubscriber needs the unified configuration of the terminal in Group, it is desirable to all MTC terminal in " waking up " Group are to receive downstream arrangements data.If the MTC terminal in Group is all in idle condition, needs all terminals successively paging according to the method for prior art, be thus repeatedly send same signaling data in a network, the signaling redundancy in network can be caused, in fact it could happen that network congestion.On the other hand, in application scenes, same downlink data needs all terminals in Group to receive, and cannot wake all terminals in Group up according to prior art in a paging flow process, and therefore the terminal in same group receives all downlink datas and has very long time delay.It is thus desirable to consider for granularity, MTC block terminal to be carried out paging with Group in MTC framework.To in independent paging terminal process, paging DRX parameter is notified core net by terminal when being attached to core net, and this terminal of core net paging adopts existing paging DRX technology.But for Group for the process of granularity paging MTC terminal, multiple MTC terminal is had in one Group, the paging DRX cycle parameter of a Group so cannot be obtained according to prior art, therefore there is certain difficulty in realizing with Group for granularity paging MTC terminal method, Group terminal cannot calculate the unified paging occasion monitoring PDCCH (PhysicalDownloadControlChannel, Physical Downlink Control Channel) channel according to the paging DRX cycle of Group.Therefore prior art has very big weak point.
