Embodiment
Fig. 1 is the schematic diagram of star net forming mode of the prior art, in the mobile communcations system of as shown in the figure star net forming, is the center of star unit with base station controller 101, and each base station 102 to 104 is connected on the base station controller 101 in man-to-man mode.The mobile communication system of this structure is carried out the arbitration that transfer of data must be passed through base station controller (as 101) in (between as 102 and 103) between the different base stations; In addition, in the rural area, mountain area or traffic route etc. are local when laying mobile communcations system, are not very desirable with the investment cost and the actual service effectiveness of the mobile communcations system of this structure construction.
Fig. 2 is the schematic diagram of daisy chain networking mode of the prior art, and a base station controller 201 is provided among the figure, and one group is connected in series to base station 202 to 204 on the base station controller 201 by sharing trunk line.Transfer of data with the mobile communication system of this networking mode networking is a chain type, must be through base station 203 when carrying out transfer of data between base station 202 and 204.This networking mode can solve existing investment cost of star net forming mode and the unfavorable problem of service effectiveness shown in Figure 1 in specific zone (as the traffic route), but still there is following problem in it: 1. its data transfer controller of providing only provides two-way fixing trunk interface, thereby makes its networking seem more stiff; 2. the base station 202 to 204 because of it all is to be connected on the base station controller 201, when it goes up construction in some other more wide zone (as the rural area, the mountain area), and the problem that still exists star net forming mode shown in Figure 1 to be occurred; 3. the reliability of this networking mode is poor, and when its base station (as 202) or a root relay line (as 211) when breaking down, its low side base station (as 203,204) can't operate as normal.
Fig. 3 adopts the network with mixed topology mode schematic diagram that apparatus and method of the present invention realized.As shown in Figure 3, comprise a base station controller 301 and a plurality of base station 302,303,304,305 in this system.Each base station all provides the N road identical trunk interface, and in a concrete system, the trunk interface that the base station provided is counted N and determined according to the requirement of system.In actual networking, if some regional communication service is more frequent, a base station 302 can be provided in this zone, and provide many shared trunk lines 311 to link to each other with base station controller 301 with 312,311 and 312 are in the mode of load sharing, and the working method of this load sharing can improve the efficient and the reliability of communication widely.And provide a plurality of base stations 303,304,305 in the not really busy zone of communication traffic, high-end base station 303 links to each other with base station controller 301 by sharing trunk line 300, low side base station 304,305 links to each other with high-end base station 303 by sharing trunk line 313,314 respectively, also is connected to each other by sharing trunk line 315 between the low side base station 304,305 simultaneously.
The mobile communication system of employing apparatus of the present invention can also be finished the networking of star fashion and daisy chaining separately.As shown in Figure 3, the relative base station controller 301 with 303 in base station 302 is star fashion; And the relative base station controller 301 with 304 in base station 303 is daisy chainings.The networking of base station is many more flexibly just like this, and can improve the efficient and the reliability of communication greatly when reducing construction cost and maintenance cost.
Fig. 4 is the schematic diagram of device residing position in mobile communication system of proposing of the present invention, described device 403 is placed in base station controller and the base station: in one embodiment, it is 4 that the trunk interface that this device 403 is provided is counted N, 401A represents the base station among the figure, 401B represents base station controller, inside at base station 401A or base station controller 401B, described device 403 links to each other with other device plates 402 by internal bus 415, and base station 401A and being connected of base station controller 401B are that device 403 by separately is through four way word trunks 411,412,413,414 realizations.
Fig. 5 is the device that the present invention proposes.In the following description, it is 4 that the trunk interface of data route transmission control device is counted N, described device comprises: data link controller 511, the data that are used to receive four road trunk lines 501,502,503,504 are handled for receiver module 512 polls, receive the data of sending module 516 and by four road trunk lines 501,502,503,504 data are sent; Data-interface 514, the data that receive bus 505 are handled for receiver module 512 polls, receive the data of sending module 516 and by bus 505 data are sent; Receiver module 512 cushions the data of four road trunk lines and data/address bus 505 and carries out route by looking into 513 pairs of these five circuit-switched data of routing table; Twoport data storage 515 is used to store the data after the route; Sending module 516 carries out poll to twoport data storage 515 each storage area and handles, and sends the data that read out by data link controller 511 and data-interface 514 bufferings from twoport data storage 515.Because data link controller 511 provides the multichannel data LI(link interface), make it to link to each other with a plurality of base stations or base station controller simultaneously, and receiver module 512 can carry out route according to 513 pairs of multichannel datas of routing table, that is to say the data that can transmit according to routing table 513 other base stations of any route or base station controller, thereby make base station or base station controller can realize mixed networking easily with device of the present invention.
The method of carrying out the data route transmission according to device of the present invention generally comprises following steps:
At first, the twoport data storage is set.The twoport data storage is divided into five storage areas, respectively corresponding five circuit-switched data (i.e. four road trunk lines, one road this base station data).
Then, configuration routing table, the content in the routing table are the base address of the twoport data storage of correspondence.
Secondly, receiver module carries out the poll route to five circuit-switched data.During to any circuit-switched data poll wherein, at first judge whether data are arranged in its corresponding buffer region, if do not have, next road of poll then, if data are arranged, then the information searching routing table that provides according to these frame data writes the corresponding storage area of twoport data storage with these frame data, then next circuit-switched data of poll.
When receiver module carries out the poll route to five circuit-switched data, sending module carries out the poll processing to five storage areas of twoport data storage, when being polled to one of them storage area, at first judge whether data are arranged in this storage area, if do not have, next storage area of poll then is if any data, then directly this circuit-switched data is write the corresponding buffering area of this circuit-switched data and send, then the next storage area of poll.
According to the convenient, flexible realization network with mixed topology in mobile communication system of apparatus and method energy provided by the invention, can solve problems of the prior art and deficiency, can also be fit to the networking mode of various different situations demands simultaneously.After adopting apparatus and method of the present invention, construction cost and maintenance cost can not only be reduced, the efficient and the reliability of communication system can also be guaranteed.
