Specific embodiment
In order that those skilled in the art more fully understand the scheme of the embodiment of the present invention, below in conjunction with the accompanying drawings and implement
The detailed description that mode is further described to the embodiment of the present invention.
It should be noted that it is existing to realize that the method for synchronizing information and base station can be used under single station pattern of present invention offer
Some digital clustering communication systems, such as：Terrestrial trunked radio (Terrestria l Trunked Radio,
TERTA), integrated digital enhanced network (Integrated Digita l Enhanced Network, I
DEN), mobile radio system (Digita l Mobile Radio, DMR), police digital cluster system (Pol
Ice Digita l Trunking, PDT) etc., as long as there is above-mentioned technical problem in system, can be using this
The method and base station for inventing offer solve the technical problem.
Refering to Fig. 1, the flow of the embodiment of the method 1 of synchronizing information is realized under the embodiment of the present invention list station pattern for showing
Figure, the method includes：
Step 101, the forwarding request that base station receiving terminal sends can be carried in the forwarding request comprising the terminal
Data volume.
In order to ensure the validity of base station and control centre's synchronizing information under single station pattern, terminal can will carry out it is small
When area switches, forwarding request is sent to its base station for being belonged to, the terminal possesses data forwarding function.What terminal was currently resident
Base station is likely to be at single station pattern, it is also possible to be not at single station pattern.
When between base station and control centre because of fault interrupting, the mode of operation of the base station is referred to as single station pattern, it is single
Base station under pattern of standing can not be with control centre's direct communication, can not be with other base station direct communications.
When base station is in single station pattern, terminal sends forwarding request to base station, and request base station sends needs and is synchronized to control
The information at center processed；When base station is not at single station pattern, terminal sends forwarding request to base station, and the base station needs to forward this
Request is transmitted to control centre, then by control centre the information for being synchronized to specified single station will be needed to be sent to the base station.Due to eventually
The data volume that end can carry itself is limited, therefore, terminal needs to be carried by carrying itself in request is forwarded
Data volume size, the size of the data volume that can be once forwarded with signals base.The data volume that terminal itself can be carried is big
The small local cache ability depending on terminal.
Step 102, when the base station is in single station pattern, the base station sends according to the data volume to the terminal
First synchronizing information, so that after the terminal switches to normal Base Station from the base station, will be described by the normal Base Station
First synchronizing information is transmitted to control centre.
The factor of other hardware such as physical link failure, net control device failure or software fault in communication system,
May result in base station to be interrupted with control centre, so as to cause base station to be in single station pattern.Base station is run under being in single station pattern,
Its service data cannot in time be synchronized to control centre, can trigger a series of problems.Therefore, this step can be forwarded by terminal
Mode realizes the synchronizing information between base station and control centre in single station pattern.Because the ability that terminal carries data has
Limit, therefore, base station sends according to the data volume size needs synchronous information, because control centre has monitored all bases in system
The information stood, therefore, base station also needs to inform the numbering of control centre itself, then the base station is included in the first synchronizing information
Numbering.
When base station of the terminal under single station pattern is switched to after normal Base Station, can be by normal Base Station by synchronizing information
Control centre is sent to, so-called normal Base Station is to refer to the base station with control centre's proper communication.Terminal may be from the base
Station is directly switch into a normal single station, it is also possible to just switch to a normal single station by repeatedly switching；By switching several times
The treatment of synchronizing information is had no effect on, as long as the terminal switches to a normal Base Station, first for just receiving before is same
Step information is sent to normal Base Station.
Because base station needs have the static data also to have a dynamic data to the synchronous data of control centre, and static data and dynamic
The method of synchronization of state data is also differed, therefore, synchronization process is performed for the ease of control centre, for the step present invention also
There is provided preferred scheme.
Preferably, when the base station is in single station pattern, the base station sends according to the data volume to the terminal
First synchronizing information, including：
The base station judges the type of data to be synchronized；
When the data to be synchronized are static data, the base station, will be comprising the static number according to the data volume
According to the first synchronizing information be sent to the terminal；
When the data to be synchronized are dynamic data, the base station, will be comprising the dynamic number according to the data volume
Terminal is sent to according to the first synchronizing information with timestamp.
Wherein, static data refer to once the data that would not be modified again after synchronization, such as call record, once exhale
After record is by synchronization, then the call record will not be modified again.Therefore for the synchronization of static data, directly preservation is
Can.
Dynamic data refers to the data that may be modified after synchronization, such as user right information.In order to ensure dynamic
The correctness of data syn-chronization, also needs to increase timestamp, to recognize the time that the dynamic data occurs, really for dynamic data
Protect the correctness of simultaneously operating.When performing synchronous, it is necessary to judge the dynamic data timestamp whether be later than it is locally modified
Timestamp, if be later than, just carries out data renewal；Otherwise, the data are ignored.
Certainly, if not differentiating between data type, base station can also be according to the data volume, will be comprising the data to be synchronized
The first synchronizing information with timestamp is sent to the terminal.Or, base station can also be according to the data volume, will be comprising described
First synchronizing information of data to be synchronized is sent to the terminal.
Step 103, when the base station is not at single station pattern, the base station forwards the forwarding to the control centre
Request, receives response and second synchronizing information for forwarding and asking that the control centre sends according to the data volume, to
The terminal forwards second synchronizing information, and second synchronizing information is the control centre to the synchronous letter for specifying single station
Breath, so as to after the terminal switches to specified single station from the base station, second synchronizing information is sent to described
Specify single station.
When the base station is not at single station pattern, illustrate to connect normal between the base station and control centre, therefore, by this
Base station will forward request to be sent to control centre, after control centre receives forwarding request, according to data volume size, to this
Base station sends the information that needs are synchronized to specified list station, i.e. the numbering that can be stood comprising specified list in the second synchronizing information,
So that terminal determines that synchronizing information is sent into which singly stands；Then, second synchronizing information is sent to end by the base station again
End, when terminal is switched to specifies under single station, is sent to specified single station, it is achieved thereby that control centre by the second synchronizing information
With the synchronizing information between single station.
Due to the possible more than one in base station in single pattern of standing in system, therefore, control centre needs to realize and multiple
Synchronizing information between single station, therefore, the information that control centre can simultaneously will assign to multiple single stations is sent to base station, so that
Corresponding synchronizing information is transmitted to specified single station by terminal when corresponding specified single station is switched to；Certainly, in order to protect
The efficiency of synchronizing information is demonstrate,proved, the information that control centre can also only will assign to a single station is sent to base station, so that terminal exists
When switching to specified single station, synchronizing information is forwarded into specified single station.
The terminal may be directly switch into from the base station specifies single station, it is also possible to just switch to finger by repeatedly switching
Order station, the treatment of synchronizing information is had no effect on by switching several times, as long as the terminal switches to specified single station, just by it
Before the second synchronizing information for receiving be sent to and specify single station.
Because terminal carries out cell switching relatively frequently, therefore, when base station of the terminal under single station pattern switches to normal base
Stand, or the base station under single station pattern is switched to from normal Base Station, single station pattern is ensure that using terminal forwarding synchronizing information
The promptness of lower synchronizing information between base station and control centre, this processing mode it also avoid caused by the low memory of base station
Information loses problem.In addition, the synchronizing process is without extra hardware device is increased, it is simple and easy to apply.
By the embodiments of the present invention it can be seen that：The method during terminal carries out cell switching, using end
The forwarding capability at end, control centre is transmitted to by the information to be synchronized of the base station under single station pattern by normal Base Station, or will
The information to be synchronized of control centre is transmitted to specifies single station, it becomes possible between the base station and control centre under the single station pattern of guarantee
The promptness of synchronizing information and the integrality of data.
Due to that may there are multiple base stations to be in single station pattern in system, therefore, realizing control centre-mono- station pattern
During synchronizing information between base station, it is to carry out letter with the base station (specifying single station) of which single station pattern that control centre needs to indicate
Breath is synchronous, therefore, for the promptness of synchronizing information being guaranteed between the base station of single station pattern and control centre, the present invention
Embodiment provides following preferred scheme, and specifically on the basis of the method for above-described embodiment 1, methods described can also include：
The base station receives the numbering to be switched single station that institute's terminal sends；

The synchronizing information that center is stood to specified list, so that after the terminal switches to specified single station from the base station, by described in
Second synchronizing information is sent to specified single station, including：
The base station to the control centre forwarding forwarding request, to the terminal forward the control centre according to
The second synchronizing information corresponding with to be switched list station that the data volume sends, so that the terminal switches to institute from the base station
State after to be switched single station, second synchronizing information is sent to list station.
During implementing, the terminal can the numbering at just to be switched single station carry in request is forwarded, institute
Stating forwarding request includes：Data volume and the numbering to be switched single station that terminal can be carried；Then the base station receives the forwarding
Request, and forwarding request is sent to control centre, then, control centre sends and to be switched single station according to data volume size
Corresponding second synchronizing information.
Be explicitly indicated control centre by above-mentioned steps carries out synchronizing information with base station under which single station pattern, in control
The heart will need the information for being synchronized to list station to be transmitted to terminal by base station, so that terminal is switched to list station (in Dan Zhanmo

The state of fixed corresponding synchronizing information.
The step introduces synchronized result feedback mechanism, i.e. base station and last synchronized result is fed back into control centre, with
Control centre is learnt last synchronizing information situation, the shape of corresponding synchronizing information is then determined according to last sync status
State, if last synchronized result is successfully, last synchronizing information is labeled as synchronous success by control centre, meanwhile,
Last synchronizing information is deleted from list to be synchronized, if last synchronized result is failure, control centre need by
Last synchronizing information re-synchronization gives the base station.Control centre and Dan Zhanmo are further ensured that by synchronized result feedback mechanism
The reliability of the synchronizing information between base station under formula.
Above-mentioned preferred scheme is to introduce synchronized result feedback mechanism in base station side, further, can also be in control
