Specific embodiment
In existing scheme, in business release flow, network side may be according to cell current loads for UE Situation, is matched somebody with somebody by wireless heterogeneous networks Connection Release (RRC Connection Release) message to UE Not busy (IDLE) state special priority information is empty, indicates UE to initiate the survey of cell on high priority frequency Amount and gravity treatment.UE confirms that network side has been issued specially after RRC Connection Release message is received With priority message, then can be performed according to the high priority frequency list for carrying and search net operation.For non- For MTC terminal, the most of cell for searching can be resident.
But, it is not that each cell for searching supports that MTC leads to for MTC terminal Letter.MTC terminal will read the master of the system message of each cell for searching after cell is searched Block of information (Master Information Block, MIB) or (the System Information of system information block 1 Block 1, SIB1) judge whether the cell supports MTC communication.MTC terminal is searching support Before the cell of MTC communication, continually may carry out looking for net to stay in the cell for not supporting MTC communication Stay, causing the power consumption of MTC terminal increases.
In embodiments of the present invention, when the RRC Connection Releases that MTC terminal receives network side transmission disappear During breath, the corresponding support MTC of each dedicated priority frequency is obtained from RRC connection release message and is led to The cell list of letter, and attempt accessing the cell in cell list.Because the cell in cell list is propped up MTC communication, therefore MTC terminal are held without blindly being carried out to all cells on each frequency Attempt resident, the net of looking for such that it is able to reduce MTC terminal is resident number of times, and then reduces MTC terminal Power consumption.
It is understandable to enable above-mentioned purpose of the invention, feature and beneficial effect to become apparent, with reference to Accompanying drawing is described in detail to specific embodiment of the invention.
The embodiment of the invention provides a kind of MTC terminal cell reselection control method, reference picture 1, below It is described in detail by specific steps.
Step S101, receives the RRC connection release message that network side sends.
In specific implementation, before step S101 is performed, can first judge MTC terminal it is current whether Currently whether communicated with network side in connected state, i.e. MTC terminal.Only when MTC ends When end is in connected state, network side is possible to send RRC connection release message, MTC to MTC terminal Terminal could now perform step S101.When MTC terminal is in other states, such as during Idle state, Network side will not send RRC connection release message to MTC terminal, without performing following processes.
In actual applications, network side can be according to Serving cell current load condition or MTC terminal The factor such as service priority come judge whether to by MTC terminal send RRC connection release message with Indicate special priority information to MTC terminal so that MTC terminal according to special priority information, from Current resident cell departs from, and is selected on the dedicated priority frequency carried in special priority information Corresponding cell is resident.
For example, when network side detect the current load value of Serving cell it is higher when, to ensure non-MTC ends The business at end is normally carried out, then RRC connection release message can be sent to MTC terminal, to indicate MTC Terminal is switched to other cells from Serving cell.
Special priority information refers to:The precedence information is just in specific some MTC end End, i.e. just for the MTC terminal, other MTC terminals will not receive the information to the information.It is special Dedicated priority frequency can be included in precedence information, the number of dedicated priority frequency can be one Or it is multiple, these dedicated priority frequencies are that network side is configured exclusively for a MTC terminal.
When MTC terminal receives the RRC Connection Release information of network side transmission, step S102 is performed.
Step S102, obtains on dedicated priority frequency from the RRC connection release message and supports MTC The cell list of communication.
In embodiments of the present invention, network side to MTC terminal send RRC connection release message when, Can also be carried in RRC connection release message and the one-to-one cell list of dedicated priority frequency, Can include that corresponding one or more of the dedicated priority frequency supports MTC in each cell list The cell of communication, namely:Each dedicated priority frequency one cell list of correspondence, each cell List includes being supported on the frequency cell of MTC communication.
MTC terminal is after the RRC connection release message for receiving network side transmission, you can therefrom obtain The cell list of MTC communication is supported on each dedicated priority frequency, and performs step S103.
Step S103, judges whether dedicated priority timer is overtime, if it is, performing step S104; If it is not, then terminating flow.
In embodiments of the present invention, when network side to MTC terminal when RRC connection release message is sent, The dedicated priority message for wherein carrying is not always can be for MTC terminal be used, dedicated priority There is certain limitation in the use time of message, the time range can generally be set by network side.Also It is to say, network side can set the time range of MTC terminal the use priority message.
In the RRC connection release message that the lateral MTC terminal of network sends, setting can be included MTC terminal can use the preset duration scope of dedicated priority message.MTC terminal may determine that currently Whether whether the moment is in the range of described preset duration to judge the expired failure of dedicated priority message.
In embodiments of the present invention, can judge that current time is by the timing of dedicated priority timer It is no in the range of described preset duration.When dedicated priority timer has not timed out, it is possible to determine that when The preceding moment still in described preset duration in the range of, dedicated priority message effectively, step can be performed S104;When dedicated priority timer expiry, then the expired failure of dedicated priority message is can be determined that, Can be with end operation flow.
Step S104, is resident, and perform cell reselection operation from the cell in the cell list.
In specific implementation, when dedicated priority message is effective, dedicated priority frequency pair can be selected Cell is selected to be resident in the cell list of the support MTC communication answered.
In embodiments of the present invention, when MTC terminal selects the cell to carry out resident in cell list, can be with First a cell for the highest priority that can be resident is selected to be resident from cell list.May in cell list Including multiple cells, each cell there may be each self-corresponding priority, and each cell correspondence Priority can be with difference.Under normal circumstances, MTC terminal is carried out in the cell of highest priority first Park operation.When attempting being successfully accessed in the cell of limit priority, then access need not be continued to attempt to small Other cells in area's list.When access failure is attempted in the cell of limit priority, then can be secondary The cell of low priority is attempted accessing.By that analogy, until MTC terminal is successfully accessed into cell list Some cell.
The priority of the cell in cell list can be set in advance by network side.Implement in the present invention In example, the current loads value of the cell that network side can be in cell list is corresponding to set each cell Priority.The corresponding priority of each cell can be with its current loads value inverse correlation, the implication of inverse correlation For:The current loads value of cell is bigger, then its priority level initializing is lower;Conversely, cell is current negative Charge values are smaller, then its priority level initializing is higher.
Native region priority is set according to cell load value to be advantageous in that:In cell list, it is understood that there may be when The larger cell of preload value, in this case, if the larger cell of current loads value is set into height The cell of priority, then when there is multiple MTC terminals accesses, it is understood that there may be again result in network congestion Situation occur, still suffer from being denied access possibility.Therefore, by by the excellent of the relatively low cell of load value First level is set to high priority, it is possible to reduce MTC terminal will not be refused to connect because cell load value is higher The possibility for entering.
Understand in actual applications, for MTC terminal, the corresponding cell of cell of highest priority Signal strength values not necessarily maximum.Therefore, in specific implementation, when MTC terminal is arranged in cell After selecting a cell to be successfully resident in table, the operation of cell measurement and cell reselection can be continued executing with, Until dedicated priority timer expiry.
In the special priority information term of validity, i.e., set in RRC connection release message in network side In the range of duration, MTC terminal can measure the corresponding signal intensity of all cells in all cell lists Value, and it is compared with the signal strength values of current resident cell.When being not detected by the presence of signal When intensity level is more than the signal strength values of current resident cell, MTC terminal can continue to reside in currently Cell;When detect the presence of signal strength values more than current resident cell signal strength values when, then may be used It is resident with reselecting to the maximum cell of signal strength values.
In embodiments of the present invention, in the cell in attempting accessing cell list, it is understood that there may be MTC ends The scene for holding any cell in attempting accessing all cell lists to fail, i.e. MTC terminal cannot connect Enter any cell in all cell lists.
For above-mentioned scene, can only be according to currently existing scheme, MTC terminal carries out full range and beats, in scanning To frequency on carry out the operation of network resident successively.However, due to MTC terminal scan it is many small Area may not support MTC communication, therefore, MTC terminal needs first to judge the cell after cell is found Whether MTC communication is supported.If supporting MTC communication, it tries resident;If not supporting, MTC leads to Letter, then select next frequency, and rejudge whether the frequency of selection supports MTC communication.
As can be seen here, using currently existing scheme, MTC terminal may multiple cells attempt it is resident after ability Find and support that the cell of MTC communication is resident, cause MTC terminal power consumption larger.
In embodiments of the present invention, when the RRC Connection Releases that MTC terminal receives network side transmission disappear During breath, the corresponding support MTC of each dedicated priority frequency is obtained from RRC connection release message and is led to The cell list of letter, and attempt accessing the cell in cell list.Because the cell in cell list is propped up MTC communication, therefore MTC terminal are held without blindly being carried out to all cells on each frequency Attempt resident, the net of looking for such that it is able to reduce MTC terminal is resident number of times, and then reduces MTC terminal Power consumption.
The embodiment of the invention provides another MTC terminal access control method, reference picture 2, with Illustrated by specific steps down.
Step S201, judges whether to need the RRC connection resources between release and the MTC terminal, If it is, performing step S202;If it is not, then end operation flow.
In specific implementation, before step S201 is performed, can also first judge that current Serving cell is The no cell to support MTC communication.Step is just performed when Serving cell is and supports the cell of MTC communication Rapid S201;Otherwise, when Serving cell is when not supporting the cell of MTC communication, it is impossible to perform the present invention Operating process in embodiment.
In embodiments of the present invention, network side can be according to the current load condition of Serving cell or MTC The factors such as the service priority of terminal come judge whether need release and MTC terminal between RRC connect Resource is connect, the MTC terminal for coming equalising network side accesses load.
For example, when network side detect the current load value of Serving cell it is higher when, to ensure non-MTC ends The business at end is normally carried out, then can be determined that the RRC connection resources that can be discharged and MTC terminal between.
When network side judges to need the RRC connection resources between release and MTC terminal, can perform Step S202;Otherwise, can be with end operation flow.
Step S202, generates cell list.
In specific implementation, each dedicated priority frequency there may be a corresponding cell list, Can include that one or more support MTC communication on the dedicated priority frequency in each cell list Cell.
In embodiments of the present invention, network side can first obtain dedicated priority when cell list is generated The load value of the cell of all support MTC communications on frequency, afterwards by the small of all support MTC communications Area's load value is compared with a preset value successively, is only added to load value less than the cell of preset value In cell list, so as to generate cell list.
In cell list, the corresponding precedence information of each cell can also be included.Network side can basis The current loads value of the cell in cell list sets the corresponding priority of each cell.Cell it is current Load value is bigger, then its priority level initializing is lower;Conversely, the current loads value of cell is smaller, then its Priority level initializing it is higher.
For example, the corresponding MTC terminal of each cell accesses number during network side can obtain cell list, The priority orders of balanced each cell, it is to avoid substantial amounts of MTC terminal is linked into same cell, causes network Congestion.
After cell list is generated, step S203 is performed.
Step S203, RRC connection release message is sent to the MTC terminal.
In specific implementation, after cell list is generated, RRC connections can be sent to MTC terminal and released Put message.In RRC connection release message, can be including dedicated priority frequency and preferential with special Level frequency supports the cell list of MTC communication correspondingly.When MTC terminal receives RRC connections After release message, dedicated priority frequency and corresponding cell list can be therefrom obtained, and trial connects Enter the cell in cell list.
