Embodiment
For the object, technical solutions and advantages of the present invention are more clearly understood, below in conjunction with attached drawing to the present invention
Embodiment be described in detail.It should be noted that in the case where there is no conflict, in the embodiment and embodiment in the application
Feature can mutually be combined.
Fig. 2 is the method flow diagram of the acquisition adjacent base station configuration information of the present embodiment.
Radio Link is established in S201 base stations with it with frequency adjacent base station；
S202 base stations obtain the own configuration information of the same frequency adjacent base station broadcast by the Radio Link；
Own configuration information with the broadcast of frequency adjacent base station may include：With frequency adjacent base station mark, configuration information content and match somebody with somebody
Confidence ceases context number；
Whenever configuration information content changes, configuration information context number can add 1；When configuration information context number reaches
During the maximum of setting, it can be started counting up again from initial setting；
Base station itself can scan it with frequency adjacent base station, obtain the configuration information that same frequency adjacent base station is broadcasted；For avoid base station because
Scanning interrupts normal operation flow with frequency adjacent base station, and base station performs above-mentioned scan operation when can be electric on it；
In addition, base station can also notify its access terminal to scan the same frequency adjacent base station, its scanning that receiving terminal reports is arrived
The configuration information that sends of the same frequency adjacent base station；To avoid receiving identical configuration information content from terminal, base station can
Only judge terminal obtain same frequency adjacent base station broadcast configuration information content update after, receiving terminal report its sweep
The configuration information content that the same frequency adjacent base station retouched is sent.
The present embodiment provide at the same time a kind of easier base station judge terminal obtain same frequency adjacent base station broadcast match somebody with somebody confidence
The method whether updated occurs for breath content：
While base station notifies the scanning of its access terminal with frequency adjacent base station, it is described adjacent with frequency that notice terminal reports scanning to arrive
Base Station Identification and configuration information context number；
Base station is judged accordingly with frequency adjacent base station according to the same frequency adjacent base station mark and configuration information context number that receive
Whether the configuration information content of transmission updates：If identical with frequency adjacent base station mark, and corresponding with the mark match somebody with somebody confidence
Context number difference is ceased, then illustrates that this is updated with the configuration information content that frequency adjacent base station is sent；At this time, base station can notify
Terminal reports the configuration information content.
Specifically above-described embodiment is described further using example with one below.
There are three cells Cell1, Cell2, Cell3, Cell4 in LTE system.
Since LTE system is using ICIC progress Inter-Cell Interference Coordination, and the main thought of ICIC is by the bandwidth of cell
Resource is divided into two parts of inner and outer rings, and the bandwidth resources of center of housing estate are the bandwidth resources of inner ring resource, cell edge or secondary lobe
It is not overlapping by outer shroud frequency domain position between ensureing co-frequency neighbor cell for outer shroud resource, so as to avoid minizone from interfering with each other.Example
Such as：Under 20M bandwidth situations, Cell1, Cell2, wireless resource block (RB) position that Cell3 outer shrouds are allocated is as shown in table 1.
Table 1
For Cell4 from its co-frequency neighbor cell Cell1, the flow that Cell2, Cell3 obtain configuration information is as follows：
Step 1：Cell1, Cell2, Cell3 base station are each by the Base Station Identification of itself, RB positions and configuration information
Hold numbering to send by broadcast message, cycle；
Step 2：Cell4 initial power-ons, scanning homogeneous-frequency adjacent-domain Cell1, Cell2, Cell3, reception Cell1, Cell2,
The broadcast message of Cell3, obtains the configuration information of Cell1, Cell2, Cell3 from the broadcast message；Disturbed to reduce,
Cell4 can set the outer shroud RB positions of itself according to the signal strength of the broadcast message of reception；
In this application example, Cell2 is farthest from Cell4, and the signal of the broadcast message from Cell2 is most weak, and Cell4 will
The RB positions of this cell outer shroud set identical with the RB positions of Cell2 outer shrouds：34~66；
Step 3：Terminal A accesses Cell4, Cell4 notice terminal A intermittent scanning Cell1, Cell2, and reports scanning
Base Station Identification, the configuration information context number of Cell1, Cell2；
Step 4：Terminal A reports the Base Station Identification of Cell1, Cell2 of scanning, configuration information context number；
Step 5：Cell4 judge the Base Station Identification of Cell1, Cell2 that terminal A is reported, configuration information context number with
The content preserved is consistent, does not notify terminal A to continue to report；
Step 6：The configuration information of cell Cell1, Cell2 is changed, and is shown in Table 2；
Table 2
Step 7：Terminal A sweep Cell1, Cell2, report the Base Station Identification of Cell1, Cell2 of scanning, in configuration information
Hold numbering；
Step 8：Cell4 judge the Base Station Identification of Cell1, Cell2 that terminal A is reported, configuration information context number with
The content preserved is inconsistent；Cell4 notices terminal A reports the RB positions of Cell1, Cell2 outer shroud；
Step 9：Cell4 changes the RB positions of itself outer shroud according to the RB positions of the Cell2 outer shrouds after renewal.
Below to undefined interface between the base stations in the case of, realize base station configuration information interactively with each other system make into
One step explanation.
The system includes base station and its with frequency adjacent base station, wherein
Base station, for obtaining the configuration information of the same frequency adjacent base station broadcast by Radio Link；
The configuration information that above-mentioned base station obtains the same frequency adjacent base station broadcast by Radio Link may include：It is same by scanning
Frequency adjacent base station obtains the configuration information of the same frequency adjacent base station broadcast, or notifies its access terminal to scan the same frequency adjacent base station,
Receive the configuration information for the same frequency adjacent base station broadcast that its scanning that the terminal reports is arrived；
Notify its access terminal to scan it with frequency adjacent base station when base station uses, receive what its scanning that the terminal reports was arrived
During the configuration information of the same frequency adjacent base station broadcast, to avoid receiving identical configuration information content from terminal, base station can
The configuration information content updated is only received from terminal, as base station notifies the scanning of its access terminal with frequency adjacent base station；Receive institute
After stating the same frequency adjacent base station mark and configuration information context number that its scanning that terminal reports arrives, according to described adjacent with frequency
Whether the configuration information content that Base Station Identification and configuration information context number judge accordingly to send with frequency adjacent base station updates；
When the configuration information content that same frequency adjacent base station is sent updates, notice terminal reports the configuration information content
The same frequency adjacent base station of base station, for broadcasting own configuration information；
The configuration information of broadcast may include：With frequency adjacent base station mark, configuration information content and configuration information context number.
