Description
Technical field
The present invention relates to communication technical field, refer to especially a kind of method, Apparatus and system of offline inspection.
Background technology
Machinery compartment (Machine-to-machine, M2M) communication is as a kind of novel communication theory, its objective is that the communication technology with number of different types organically combines, as: machine is to machine communication, apparatus control communication, man-machine interaction communication, mobile interconnected communication, thus the development of promotion social production and life style.The business of future Human To Human communication may only account for 1/3 of whole terminal market, and the communication of larger quantity is machinery compartment (M2M) communication service.
Current mobile communications network designs for interpersonal communication, as determining etc. of: network capacity.If wish to utilize characteristics that mobile communications network supports that M2M communication just need to communicate by letter according to M2M that the mechanism of mobile communication system is optimized, in order to can not be subjected to or be subjected to less the impact in the situation that traditional person to person is communicated by letter, realize better M2M communication.
The machine type communication of a reality (Machine Type Communications, MTC) terminal can have following one or more characteristic: the MTC terminal has Hypomobility; The time that MTC terminal and network side carry out transfer of data is controlled; Be that the MTC terminal can only access within the time period of network appointment; The transfer of data that MTC network and network side carry out is not high to requirement of real-time to transfer of data, has the time tolerance that is:; MTC terminal energy constraint requires extremely low power consumption; Only carry out the communication of small data quantity between MTC terminal and network side; The MTC terminal can manage take group as unit; Need to monitor the state of MTC terminal, if find that certain MTC terminal is in off-line state, needs to notify corresponding network element device.
For top need to detecting and the characteristic of off-line notice the MTC SOT state of termination of addressing, main application scenarios is: communicate by letter with H2H different, because MTC equipment may be under long unmanned monitoring situation, in the time can't continuing to communicate by letter between equipment and network (may due to link-quality variation, also may be due to unexpected or artificial equipment damage etc.), network needs the state of this equipment of detection that system can be initiatively and reports relevant network element entity, so that can be taked corresponding counter-measure.This characteristic has defined that " maximum off-line indication detection time is " (namely from actual generation disconnecting to time that this disconnecting is detected, the back is called MAX_T_Detect), the requirement system can (based on the MTC CAMEL-Subscription-Information) detect MTC equipment off-line event within this time period, the length of this time may be 1 minute to 1 hour.
In present UMTS system, for the strategy of state-detection and the notice of terminal equipment, roughly situation is as follows:
For the terminal that is in idle pulley, terminal monitoring paging channel (PICH) also reads the system broadcast information of residential quarter, periodically carries out simultaneously the position and upgrades.When the position of terminal being arranged to off-line indication detection time update time, network side can be initiated periodic location update by terminal, obtains terminal and whether is in off-line state.
For the terminal that is in connection mode, there are following several situations:
1) terminal is in the CELL_DCH state
Under this state, what require that terminal and network must keep eating dishes without rice or wine is synchronous, therefore existing corresponding mechanism makes network can detect the quality of uplink quality, DPCH) or up non-scheduling resource (non-scheduling resource) such as in the situation that configured and follow DPCH (DedicatedPhysical Channel:, base station equipment can directly judge link-quality based on the reception condition of upstream data; Follow DPCH or up non-scheduled in the situation that do not exist, the base station need to go maintenance link synchronous by periodic scheduling.Therefore, under the CELL_DCH state, network can in time be understood the state information of terminal, uses existing technology can guarantee " to the state-detection of terminal equipment ".
2) terminal is in the CELL_FACH state
Under this state, terminal equipment is not assigned with special-purpose physical resource, in the situation that there is no transfer of data, terminal need not to keep uplink synchronous, terminal need to be monitored descending FACH channel or need to monitor the HS-SCCH channel in HSPA+, sets up in order in time trigger uplink synchronous the transmitting-receiving that process is carried out data.Under this state, periodic cell update mechanism is arranged, network can know whether terminal is in off-line state by the periodic cell update that terminal is initiated.
3) terminal is in CELL_PCH or URA_PCH state
Under this state, terminal equipment is not assigned with special-purpose physical resource, and terminal only need to be monitored the PICH channel, does not need to keep uplink synchronous, has in the situation of data transmission, need to first transfer to the CELL_FACH state.Under this state, periodic cell update mechanism is arranged, network can know whether terminal is in off-line state by the periodic cell update that terminal is initiated.
Can find out from above-mentioned analysis, at present for the terminal that is in CELL_FACH, CELL_PCH/URA_PCH state, although network can judge according to the periodic cell update of terminal whether terminal is in off-line state, but because cell updating course ends at RNC, therefore for the terminal that is in CELL_FACH, CELL_PCH/URA_PCH state, core net is not also known whether off-line of this terminal; The time of the periodic cell update of network side configuration is simultaneously informed terminal by system message 1, namely this time is the parameter of a cell level, for terminal equipments all under this residential quarter, do not distinguish the MTC equipment of needs " off-line indication " and common terminal.For the terminal that does not need to support " off-line indication ", do not need to carry out periodic cell update according to the offline inspection time, especially when the offline inspection time during in minute level, do not carry out frequently periodic cell update if do not need to support the terminal of " off-line indication ", increase greatly the signaling traffic load of eating dishes without rice or wine, caused Radio Resource congested.In addition, the time that the MTC equipment off-line under same residential quarter detects also may be different, therefore need to be set the periodic cell update time based on each MTC equipment.
Based on above-mentioned situation, for the MTC characteristic of " offline inspection and notice ", need to carry out certain improvement to existing mechanism, this characteristic of support that can be more excellent.
