Technical scheme of the present invention is described in detail below in conjunction with Fig. 5 and Fig. 6.
The Managed Solution of the MTC terminal group that the present invention proposes mainly realizes by means of RAN side technology, specifically can be divided into following two schemes:
Scheme one:
Based on the RAN side MTC terminal management and group mechanism that system information broadcast strengthens.As shown in Figure 5, this mechanism does not need to increase new physical layer channel and logic channel, but needs to introduce new SIB in the system information SI of broadcast channel.This system information block is for the MTC terminal group transmission management information under some or cluster base station coverage.
Information index that can be corresponding with MTC group is directly or indirectly included in the new SIB introduced.Wherein, direct information index comprises the mark of group, collateral information index can make any dominant or recessive parameter corresponding with this MTC terminal group that can be obtained after calculation by some or all MTC terminal of MTC group, as specific time/frequency source block etc.
The program is introduced in network side if MME place is to the information of management and group, processes in conjunction with network topology structure.Such as, MME, by relevant group's management entity, judges that the terminal in these groups is under the covering of which community at present, thus determines which community needs to receive these information.
The program introduces the signaling message of the new handling process of MME and S1-MME.Such as, these information is realized this object by S1-MME message (can be add new information element or define new S1-MME message in the defined message of 3GPP 36.413) by MME.According to the confidentiality of information with understand the need of eNB (base station), can select to be transmitted by S1-MME after NAS infill layer, or do not encrypt and directly transmit with S1AP control message, allow eNB solve information element or further revise.
Particularly, as shown in Figure 5, core network entity (Core Network Entity), as MME collects MTC clustered control information, by after group processing, be assigned to eNB/cell (community), and as system information transmissions to the terminal in MTC terminal group (Group x).Core network entity can be EPC (Evolved Packet Core, 4G core network) entity.
Scheme two:
Based on the RAN side MTC management and group mechanism of D2D/MTC gateway relay.As shown in Figure 6, in this mechanism, network node is as MME or eNB, if the equipment in precognition MTC terminal group has D2D ability/MTC gateway ability, part MTC terminal in group then can be selected as first communication object of group control and data message, the mark of MTC terminal group is informed selected terminal, so that control information can arrive all MTC terminal needed in the MTC terminal group arrived.
Because this mechanism may need distributed distribution of information, whether received information is the information received to need MTC terminal to identify.Therefore, the time limit parameter comprising such as life cycle and so in the block of information issued is needed.Meanwhile, this mechanism needs the faith mechanism depended in group, namely supposes that MTC terminal is trusted mutually.For the MTC terminal not supporting D2D technology, by the some gateway nodes in MTC terminal, information can be forwarded this MTC terminal.
The program introduces network side to the judgement of terminal behavior and matching mechanisms.Such as, MME (also can be through the eNB of enhancing), according to the D2D ability in MTC group and/or MTC gateway ability, selects the MTC terminal of unicast transmission control information.Select the criterion of this MTC terminal also can include but not limited to the electricity-saving characteristic facility, mobility statistical information, group's stability (whether having the frequent statistical information changing management and group) etc. of terminal.
The program introduces the selection mechanism of D2D via node.The standard selected can based on wireless coverage situation, such as, from the information forward node that the terminal prioritizing selection that macro base station is closer is first, or the node being in group center (no matter distance macro base station far or nearer) also can as first information forward node.The program is also applicable to not supporting D2D relay, but carries out the MTC group of distribution of information by MTC gateway equipment.Selected terminal also can be not limited to the D2D ability/MTC gateway ability of MTC group or terminal, for the selection of this Terminal Type, may be based on utilizing application layer technology or other technologies to obtain corresponding information from MTC ISP.
Particularly, as shown in Figure 6, core network entity (Core Network Entity), as MME collects MTC clustered control information, by after group processing, select specific MTC terminal, and then directly or by eNB, control information is forwarded to specific MTC terminal, forwarded as relaying by MTC terminal.
Above-mentioned two schemes can introduce the priority mechanism that EPS (Evolved Packet System, evolved packet system) carries rank.Particularly, as the business relating to the outbalance such as public safety, personal health, network side such as MME can use Internet resources with higher priority.Specific implementation needs MME, HSS (Home Subscriber Server), P-GW, S-GW configure accordingly on strategy, and the link such as business authentication and mandate all supports this priority.When control information is distributed in RAN side, base station equipment can be implemented according to the use priority of the Radio Resource of network side configuration, specifically as transmission frequency, SRB (the SignalingRadio Bearer of system information, Signaling Radio Bearer), DRB (Data Radio Bearer, Data Radio Bearer) level etc. uses the priority etc. of Radio Resource.
Technique scheme of the present invention makes it possible to the management realizing the MTC terminal based on group by means of RAN side technology, and reaches high efficiency management and control.Meanwhile, the efficiency of management of the business of MTC group service and extensive dense deployment, reliability and throughput can also be improved, wearable Internet of Things application scheme and scene also be had and supports value accordingly.
More than be described with reference to the accompanying drawings technical scheme of the present invention, the present invention proposes a kind of Managed Solution of new MTC terminal group, achieve and from network side, the management of MTC terminal group is controlled, improve the efficiency of management to MTC terminal group, do not need to change in a large number MTC terminal simultaneously, meet the requirement reducing MTC device cost.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
