Need exist for explanation be：In existing system, the mobile management under idle condition includes that cell is selected and small
Area's gravity treatment.Cell selection operation is performed after M2M starting up of terminal, selects to be resident to a suitable cell to be taken by cell
Business.M2M terminals are by periodically measurement Serving cell and other same frequencies（Intra-frequency）, alien frequencies（Inter-
frequency）With different wireless access technology（Inter-RAT）The channel quality of cell, is resident the more preferable cell of channel quality
On, this process is cell reselection.
For the M2M terminals with Hypomobility characteristic, the channel measurement defined in existing standard is too frequent.Due to
M2M terminal mobilities are relatively low, and the change of channel large scale decline in a short time will not be very big, so need not carry out very frequently
Channel measurement.
In the prior art, the maximum measure the cycle to Serving cell is determined by two parameters, and first parameter is to be
The cell defaultPagingCycle included in system message SIB2, second parameter is the parameter of M2M terminals upper strata generation
DRX_Cycle, then the maximum measure the cycle to Serving cell is：TH1=min { defaultPagingCycle, DRX_
Cycle }, i.e. take the minimum value in two parameters.In existing standard, the span of defaultPagingCycle is
{ 0.32s, 0.64s, 1.28s, 2.56s }, that is to say, that the maximum measure the cycle to Serving cell is 2.56 seconds, and this is to M2M ends

SnonIntraSearchP, and the serving cell channel quality Squal for receiving is more than the second threshold value
When SnonIntraSearchQ, M2M terminals have the Inter-frequency/ of higher priority every TH3 time detectings
Inter-RAT cells.To the cell for detecting, one-shot measurement is carried out every the TH4 times.Increase detection cycle and measurement week
Phase, can respectively define and multiply sex factor P and Q more than 1 so that the Inter-frequency/ of M2M terminal-pair higher priority
The Inter-RAT cell detection cycles are increased to TM3=M*TH3 by TH3 so that the Inter- of M2M terminal-pair higher priority
The frequency/Inter-RAT cell measurement cycles are increased to TM4=N*TH4 by TH4.
In the prior art, it is being configured without discontinuous reception（DRX）In the case of, the terminal-pair in connection status
The measure the cycle of Intra-frequency cells is 200ms.In the case where DRX is configured, when DRX cycle is less than or equal to 0.04s
When, the measure the cycle of the terminal-pair Intra-frequency cells in connection status is 200ms；When DRX cycle is more than
0.04s and during less than or equal to 2.56s, the measure the cycle of the terminal-pair Intra-frequency cells in connection status is 5
Individual DRX cycle.Multiply sex factor V more than 1 by defining one in the above method so that M2M terminal-pairs Intra-frequency
The measure the cycle of cell is expanded to original V times.
In existing system, the measurement of the terminal-pair Inter-frequency cells under connection status is needed in measurement interval
（Measurement Gap）Interior completion.In measurement interval, the data transfer of terminal aborts and Serving cell.Measurement interval is
Network side is allocated to UE's, presently, there are two kinds of measurement interval configurations.The configuration of the first measurement interval is every 80ms measurements
6ms, second measurement interval configuration is to measure 6ms every 40ms.After measurement interval is configured with, terminal can be periodically right
Inter-frequency cells are measured.In order to save the power of measurement consumption, for the M2M with Hypomobility characteristic
Terminal, can increase measure the cycle.One can be defined and multiply sex factor W more than 1 so that M2M terminal-pairs Inter-
The measure the cycle of frequency cells is expanded to original W times.
It is preferred that described K, L, P and Q can be allocated to by network side by attaching process or by broadcast message in advance
The M2M terminals.The V and W can be allocated to the M2M terminals by network side by RRC reconfiguration messages in advance.
Further, in order to save the power consumption of channel measurement, M2M terminals can disable channel matter when suitable
Measurement mechanism, and be then turned on when thering are data to transmit.Specifically, this purpose can be realized using following methods：
When M2M terminals are in idle condition, if the Hypomobility of the M2M terminals belongs to not mobile type, the M2M terminals exist
After start completes cell selection and first cell reselection, stopping carries out the measurement of the cell channel quality, until there is data to arrive
During up to the M2M terminals；When M2M terminals are in connection status, if the Hypomobility of the M2M terminals belongs to is not moved class
Type, then the M2M terminals set up after RRC is connected with current service cell, stopping carries out the measurement of the cell channel quality, directly
When thering are data to reach the M2M terminals.
Further, the method for the above-mentioned measurement for carrying out cell channel quality in extended cycle manner can be with routine
Periodic channel measurement（The channel measuring method that i.e. H2H terminals are used in system）It is combined, to improve to M2M terminals
The flexibility of mobile management.This purpose specifically can be realized using following methods：
In M2M accessing terminal to network, and channel quality measurement mode according to the H2H terminals of system completes cell and believes
Before road mass measurement, M2M terminals know that itself has Hypomobility according to the notice of network side；
