The method of DMTC information, applied to first base station, this method includes：
Step 101, the DMTC information for the first community that the second base station is sent by the neighboring BS information of the second base station is obtained.
Wherein, above-mentioned first community is the adjacent cell of the serving cell of the second base station, and the second base station can be first base station
Adjacent base station, may not be the adjacent base station of first base station, and first base station may each be MF base stations, LTE bases with the second base station

(GSM) base station.
And in the first embodiment of the present invention, it can obtain and (receive) according to X2 interface message or S1 interface messages
The DMTC information for the first community that second base station is sent.Wherein, the DMTC information records of first community in X2 interface message or
In the neighboring BS information of second base station of S1 interface messages.It should be noted that identify first community for ease of first base station, it is above-mentioned
X2 interface message should all include the network identity (NHN-ID) and Cell Global Identifier of first community with S1 interface messages
(ECGI)。
Step 102, the DMTC information of the first community got is stored in the neighboring BS information of the second base station.
Wherein, the DMTC information of the first community got includes the first DMTC information and/or the 2nd DMTC information.Its
In, the first DMTC information is this cell DMTC information of first community, and the 2nd DMTC information is the co-frequency neighbor cell of first community
DMTC information and/or iso-frequency adjacent community DMTC information.
Specifically, this cell DMTC information of first community includes the DMTC parameters of this cell of first community, first is small
The DMTC parameters of this cell in area specifically include：DMTC window durations (dmtc-duration), the cycle of DMTC windows
(dmtc-Periodicity) and sub-frame offset (dmtc-Offset).2nd DMTC information is first community in system information
The one or more iso-frequency adjacent communities broadcasted in the co-frequency neighbor cell DMTC information and/or system broadcasts SIB5 broadcasted in SIB3
DMTC information.Wherein, co-frequency neighbor cell or iso-frequency adjacent community DMTC information include sync id, refer to when sync id is asynchronous
Show that the co-frequency neighbor cell of first community or alien frequencies are adjacent comprising the cell asynchronous with first community in the co-frequency neighbor cell of first community
DMTC parameters and/or the neighbour asynchronous with first community that the adjacent cell synchronous with first community is further included in cell DMTC information are small
The DMTC parameters in area.The DMTC parameters of synchronous adjacent cell or the DMTC parameters of asynchronous adjacent cell include DMTC window durations
(dmtc-duration), one in the cycle (dmtc-Periodicity) and sub-frame offset (dmtc-Offset) of DMTC windows
Item is multinomial.
As can be seen that in the case of there is no direct communication interface between first base station and first community own base station, the
One base station can still obtain the DMTC information of first community from the neighboring BS information that the second base station is sent so that first base station energy
The co-frequency neighbor cell DMTC information of first base station cell and/or different is sent to terminal according to the DMTC information of the first community of preservation
Frequency adjacent district DMTC information, and then it is signal quality measured that terminal is enable to carry out DRS in adjacent cell DMTC windows, reduces eventually
The effect of the power consumption at end.
Further, in the first embodiment of the present invention, a kind of specific implementation of above-mentioned steps 102 includes as follows
Step：The DMTC information of first community got is detected whether comprising sub-frame offset, if wherein detection get it is first small
The DMTC information in area includes sub-frame offset, then the sub-frame offset of the DMTC information of the first community got is converted to DMTC windows
Sub-frame offset of the mouth under the subframe timing of first base station, obtains the DMTC of the first community after sub-frame offset conversion process
Information, and the DMTC information of the first community after sub-frame offset conversion process is stored in the neighboring BS information of the second base station
In；Wherein, in the concrete realization, first base station may obtain first community by monitoring the downlink synchronous signal of first community
Subframe timing, so as to be converted to the sub-frame offset of the DMTC information of the first community received under first base station subframe timing
Sub-frame offset, wherein, first community and first base station are either synchronously or asynchronously.
Another specific implementation of above-mentioned steps 102 includes：Determine whether first community is asynchronous with first base station；If
First community is asynchronous with first base station, then will not include the DMTC of the first community of sub-frame offset (i.e. in addition to sub-frame offset)
Information is stored in the neighboring BS information of the second base station.First base station determines that the whether asynchronous method of first community includes：If it receives
The DMTC information of the first community arrived does not include sub-frame offset, it is determined that first community is asynchronous with first base station；Alternatively, the first base
It stands and determines that first community is asynchronous with first base station according to the OAM synchronizing informations on first community configured；Alternatively, first base station
By determining that first community is asynchronous with first base station to first community own base station inquiry synchronizing information.For example, first base station
Forwarding (eNB Configuration Transfer) message can be configured by the base station of S1 interfaces to inquire belonging to first community
The synchronizing information of base station, wherein, first base station is by the SON Information of eNB Configuration Transfer
Request fields are set to time synchronization information (Time synchronisation Info) enumerated value；First community own base station
The S1 message eNB Configuration Transfer comprising synchronizing information are sent to indicate whether to first base station after receiving
It is asynchronous with first base station.Further, if first base station determines that first community is synchronous with first base station, first base station can will receive
To the sub-frame offset of DMTC information of first community to be converted to subframe of the DMTC windows under the subframe timing of first base station inclined
It moves, obtains the DMTC information of the first community after sub-frame offset conversion process, and will be after sub-frame offset conversion process
The DMTC information of first community be stored in the neighboring BS information of the second base station.
Wherein, it is necessary to illustrate, when the DMTC information of the first community received includes sub-frame offset, if docking
The sub-frame offset of the DMTC information of the first community received is converted, and depends primarily upon the DMTC letters of the first community received
Whether the sub-frame offset of breath has been subjected to conversion.If specifically, the second base station antithetical phrase when sending the DMTC information of first community
Vertical shift is converted, then first base station when receiving the DMTC information of first community just need not again to sub-frame offset into
The DMTC information of the first community received, is directly stored in the neighboring BS information of the second base station by row conversion；And if
Sub-frame offset is not converted when sending the DMTC information of first community two base stations, then first base station is receiving first
It just needs to convert sub-frame offset during the DMTC information of cell, and upon the transition, sub-frame offset conversion process will be passed through
The DMTC information of first community afterwards is stored in the neighboring BS information of the second base station.
Here, above-mentioned first base station is expanded on further to the DMTC information of first community that receives with a specific example
The process that sub-frame offset is converted.For example, the DMTC information for the first community that the second base station that first base station receives is sent
Sub-frame offset is 9, and it is 1 that first base station, which calculates sub-frame offset of the first community DMTC windows under first base station subframe timing, that
First base station preserves after the sub-frame offset of the DMTC information of first community being set to 1 at this time.
Wherein, in the first embodiment of the present invention, after above-mentioned steps 102 have been performed, the above method further include to
Terminal sends the step of co-frequency neighbor cell DMTC information of first base station serving cell and/or iso-frequency adjacent community DMTC information.And
The co-frequency neighbor cell DMTC information of first base station cell and/or specific the step of the DMTC information of iso-frequency adjacent community is sent to terminal
Realization method is：According to the DMTC information of the first community of preservation, pass through system broadcasts or special measurement allocation radio resource control
RRC cells processed send the co-frequency neighbor cell DMTC information of first base station cell and/or iso-frequency adjacent community DMTC information to terminal.When
So it is understood that first base station is sending the co-frequency neighbor cell DMTC information and/or alien frequencies of first base station cell to terminal
During adjacent cell DMTC information, first base station can be stored in the DMTC information of one or more first communities based on itself, to end
End sends the co-frequency neighbor cell DMTC information of first base station cell and/or iso-frequency adjacent community DMTC information.So that terminal can be
It is signal quality measured that DRS is carried out in adjacent cell DMTC windows, achievees the effect that reduce power consumption of terminal.
Wherein, in the first embodiment of the present invention, above-mentioned X2 interface message can be that X2 establishes request message, X2 is established
Response message, base station configuration updating information, base station configuration updating response message or DMTC response messages.It should be noted that
Either above-mentioned any X2 interface message, the DMTC information of above-mentioned first community are recorded in the adjacent area letter in X2 interface message
