Description
Technical field
The present invention relates to the communications field, the method, apparatus of more particularly to a kind of change detection pattern in LTE system and it is
System.
Background technology
In mobile network's networking, because environment is changeable, and demand and requirement would also vary from, and it is special to have some
Scene.There can be the problem of some are special under special screne, these specific questions can directly affect actual network organizing
Energy.Need to propose different targetedly processing methods and Networking Solutions ＆ provisioned for these special screnes.
In current all 2G, 3G GSMs, the single frequency point bandwidth of base station system all immobilizes
, mobile terminal only exists the change of frequency in moving process, in the absence of the change of frequency bandwidth.
And in LTE system, the communication frequency bandwidth of system is in the presence of change（With current standard, including 4 kinds of feelings
Condition：1.25MHz, 5MHz, 10MHz, 20MHz）, terminal is in moving process, if this change information can not be obtained in time, with
Its original system bandwidth mode removes demodulating data, will result in call drop phenomenon.
In LTE（Long Term Evolution, Long Term Evolution）In system, the information of system bandwidth is by PBCH
（Physical Broadcast Channel, Physical Broadcast Channel）It is transmitted, wherein system bandwidth information 3bit, respectively generation
Table system bandwidth is 1.25MHz, 5MHz, 10MHz, 20MHz.There are System Frame Number information 8bit, PHICH in addition（Physical
Hybrid ARQ Indicator Channel, Physical HARQ Indicator Channel）Structural information 3bit, add up to 14bit, entered by PBCH
Row CRC（Cyclic Redundancy Check, CRC）Broadcasted after processing and channel coding.Terminal is being opened
PBCH information can be received after machine search synchronization, obtains relevant rudimentary information.Under normal Standby state, terminal is in order to save electricity
Can, resting state can be kept as far as possible and reduce waking state.Because system bandwidth will not change in general,
Terminal is not necessarily to every 10ms and all goes detecting system bandwidth information, is all no variation in the case of so big absolutely number, terminal is not
Disconnected will necessarily consume substantial amounts of electric energy and CPU from dormant state into state is received（Central Processing Unit, center
Processing unit）Process resource, the stand-by time to mobile phone bring larger challenge, and in current 3G communication systems, big portion
Wake cycle under the holding state divided is both greater than 1000ms, and to save mobile phone electric energy, and system can configure different paging weeks
Phase is further to save electric energy.

With a kind of means of frequency resource, but this set will necessarily bring problem.Fig. 1 is that the network of LTE system in the prior art shows
It is intended to.As shown in figure 1, in the first region, the frequency bandwidth of each base station is 10MHz, in the second area, the frequency of each base station
With a width of 5MHz.In the first region, for the 1st row base station, due to the frequency bandwidth of each base station and the frequency band of adjacent base station
It is wide identical, therefore the 1st row base station is referred to as time edge base station；And for the 2nd row base station, due to frequency bandwidth and the phase of each base station
The frequency bandwidth of adjacent base station is not fully identical, therefore the 2nd row base station is referred to as into edge base station.Equally, in the second area, will
3rd row base station is referred to as edge base station, and the 4th row base station is referred to as into time edge base station.
Due to the frequency bandwidth of edge base station and adjacent base station not fully, therefore, user terminal is in moving process
In, if this information change process can not be obtained timely and effectively, the loss of user data package is will result in, causes user to fall
The raising of words rate and the percent of call lost, or even the situation that user can not normally access occurs.
