Further, the embodiment of the present invention also provides a kind of communication means, and method flow as shown in figure 10.

The application scenarios of this data transmission method can be: the transmission link of the first base station and affiliated the first base station controller interrupts, and the first base station enters fault mode; The second community, place, base station and the first adjacent area each other, community, place, base station, the transmission link between the second base station and affiliated the second base station controller is intact, can provide communication service for subscriber equipment in managed community, claims the second base station in service mode.The method that adopts the present embodiment to provide, can make the subscriber equipment in cell coverage area under the first base station in fault mode normally communicate business.

1001: data transmission set connects with the first base station, the second base station respectively.

Concrete, described data transmission set being arranged in the overlapping region of two adjacent areas, described equipment can search the network information of the first base station and the transmission of the second base station simultaneously, can be linked in described two adjacent areas.

For the reliability of transfer of data, described data transmission set can in the time that the transmission link of the first base station and the first base station controller does not damage, setting completed, and described data transmission set can keep operating state always, once transmission link damages, can carry out in real time transfer of data, avoid causing of short duration transmission to stagnate, affect telecommunication service quality.In actual applications, also can after described transmission link damages, arrange again and open described data transmission device, can accurately locate the position of fault cells, save cost and the energy consumption of setting device.

Data transmission set is determined respectively the position of the first base station and the second base station by receiving the cell information of the first base station and the second base station broadcast, and initiate random access request to described two base stations respectively, receive after the accidental access response message of base station feedback, described data transmission set accesses the first base station and the second base station and can carry out transfer of data, comprises transmission PS business.The first base station and the second base station also can obtain the identifying information of described data transmission set, such as geographical location information, identification number, IP address etc., described the first base station or the second base station can be identified the up PS business or the descending PS business that receive and sent by described data transmission set.

Concrete, before the first base station enters fault mode, although described data transmission set can search out the signal sending the first base station and access the first base station, but now, because the transmission link between the first base station and the first base station controller is intact, can normally carry out data interaction, the first base station sends to described equipment without configuration data or business datum etc. being converted to special PS business, therefore before entering fault mode in the first base station, described equipment can only complete the preparation of access the first base station and the second base station, in wait state.

After the first base station enters fault mode, although the disconnecting of the first base station and the first base station controller, but in order to make the first Xia community, base station keep not moving back clothes, the first base station still keeps carrier frequency power and cell information (for example cell ID, community frequency range etc.) broadcast, the signal that assurance data transmission set still can search the first base station is connected with its maintenance, and then first base station can convert the configuration data of self and practical communication business datum to PS business datum and send to described data transmission set, completed the forwarding of described PS business datum by described equipment.The second base station controller, by receiving the configuration data of the first base station, can manage community under the first base station, comprises the management of wireless network resource, management, base station transmitting power control, cell localization and the switching etc. of cell configuration data.

For realizing the management of the second base station controller to the first base station, first the second base station controller will obtain the configuration data of the first base station, and makes adjustment according to network actual conditions.Concrete steps comprise 1002-1008.

1002: the first base stations, by the configuration data of self, convert to after up PS business, send to data transmission set by air interface.

Above-mentioned configuration data can comprise the carrier resource information of cell information, neighboring BS relationship and community handoff parameter, base station, all base station configuration datas that the base station controllers such as resource information are required.Above-mentioned configuration data can be pre-stored in base station, meanwhile, in the time that the configuration data of base station changes to some extent, the configuration data of synchronously storing in updating device, real-time, accuracy and the consistency of assurance configuration data, insure telecommunication service quality.

1003: after the up PS business being converted to by the configuration data of the first base station described in data transmission set identification, be forwarded to the second base station by air interface.

Within 1004: the second, base station is according to the identifying information of described data transmission set, determine that described up PS business is sent by described data transmission set, and be reduced into the configuration data of the first base station, described configuration data is sent to the second base station controller by Operation and maintenance link (OML, operation and maintenance link) by the second base station.

1005: the second base station controllers preserve and the fault mode that comes into force under the configuration data of the first base station, the described configuration data that comes into force the first base station refers to, can make corresponding adjustment to described configuration data according to the actual state of the second base station controller and network actual demand.And the configuration data after adjusting is handed down to described the second base station.

Comprise: the transfer resource to the first base station is adjusted, due to before transmission link fault, the transfer resource of the first base station is distributed by the first base station controller, corresponding transfer resource may be taken by other base stations on the second base station controller, therefore needs described transfer resource adjustment.For example, the transfer resource that the first base station controller is distributed to the first base station is 0 port 2 time slots of E1 circuit, send to after the second base station controller in these transfer resource data, the second base station controller can take situation according to current time slots, whether 0 port 2 time slots that judge E1 circuit have distributed to the base station that other are managed by the second base station controller, and then the transfer resource of distributing to the first base station can be adjusted into other free timeslots.

The second base station controller also can be adjusted the signaling node information of the first base station.The community that described signaling node information is the first base station is before the transmission link fault of the first base station and the first base station controller, the nodal information of using while carrying out data interaction by the first base station controller and core net, described nodal information is corresponding with the first controller.Therefore, managed behind the first base station by the second base station controller, BSC2 need to be adjusted into the signaling node information corresponding with BSC2 by described signaling node information.For example, before fault, the signaling node of the community of the first base station on the first base station controller is 200, is in charge of under the first base station and the first base station behind community by the second base station controller, needs to be converted to the upper corresponding nodal value of BSC2.

The second base station controller can also be adjusted the carrier resource configuration of the first base station.The power that the first base station is used before fault, the information such as frequency are determined by the first base station controller, after the first base station is by the second base station controller management, power or frequency that the first base station is used may be used by other base stations under the second base station controller, therefore, the second base station controller can be adjusted this, avoids conflicting with other base stations.

The configuration data of described the first base station through adjustment comprises, is transfer resource data and the carrier resource data etc. that the first base station is redistributed.Described carrier resource data comprise after adjusting, the information such as the carrier frequency, transmitting power, signaling node that can be used by the first base station.

One of major function of base station controller is the management to wireless transmission resources, is each cell configuration business and control channel under managed base station.Therefore be, that to redistribute suitable transfer resource be important work of the second base station controller in the first base station.In order to carry out accurately reconfiguring of transfer resource, the second base station controller can be collected the various statisticss about the first base station.Such as the quantity that in the community of the first base station, subscriber equipment loss is called out, the success rate that switch community, the traffic carrying capacity of community, wireless network environment etc.Described statistics can add up and be converted to after PS business datum by the first base station, through described data transfer equipment and the second base station, is transmitted to the second base station controller, for the second base station controller.

The second base station controller is according to above-mentioned configuration data, completes the resource distribution of the first base station is upgraded, and forms a new base station sub-system with the first base station by the data transmission channel of eating dishes without rice or wine, and provides normal communication service to subscriber equipment in community under the first base station.

Within 1006: the second, receive after configuration data base station, preserves the second base station controller and distribute to the resource information of the first base station, and the configuration data that sends to the first base station is converted to descending PS service concurrence delivers to data transmission set.

1007: the descending PS business that data transmission set is converted to the configuration data after above-mentioned adjustment is forwarded to the first base station by air interface.

Described in 1008: the first identification of base stations, descending PS business, parses the configuration data wherein comprising, and the configuration that comes into force ensures that cell transmit power is normal.

Utilize the air interface of data transmission set to forward the configuration data of the first base station, the second base station controller can replace the first base station controller, community under the first base station is managed, between the first base station and the second base station controller, set up the data transmission channel of eating dishes without rice or wine, the subscriber equipment of the first community under base station can be proceeded communication service, carries out the mutual of all kinds of business datums on the described data transmission channel of eating dishes without rice or wine.

The configuration data upgrading comes into force in the first base station, realize the second base station controller to after the management of the first base station, described method can also comprise the call signalling flow that the subscriber equipment in the first community, place, base station is initiated, and concrete steps are as shown in 1011-1017.

It is to be noted, the configuration data of above-mentioned the first base station is via the second base station controller adjustment or modification and after returning to the first base station and coming into force, all communication services after the first base station are had to impact, the first base station can be used described adjustment or amended configuration data always, without repeatedly reporting configuration data to the second base station controller.But in actual applications, if at the first base station run duration, described configuration data need to be made adaptability revision according to network practical operation situation, the second base station controller also can be handed down to the first base station again by amended configuration data, used the configuration data upgrading by the first base station, promote traffic handing capacity.

The signaling data transmission of up direction comprises step 1009-1011.

1009: up direction, the subscriber equipment in the community in the first base station is initiated voice call request, and signaling data required audio call is sent to the first base station.

Within 1010: the first, described signaling data is converted to up PS business by base station, sends to data transmission set by air interface, and data transmission set is forwarded to the second base station by air interface by described up PS business.

Up PS business described in 1011: the second identification of base stations, and parse the signaling data wherein comprising, according to the transfer resource of distributing to the first base station, signaling data is sent to the second base station controller.

The signaling data transmission of down direction comprises step 1012-1015.

1012: down direction, the signaling data that is handed down to the first base station is sent to the second base station by the second base station controller.

Within 1013: the second, base station is given data transmission set by air interface by being converted to descending PS service concurrence after the signaling data of down direction.

1014: the descending PS business that data transmission set is converted to above-mentioned signaling data by air interface is forwarded to the first base station.

Because the second base station controller is managed the first base station and the second base station simultaneously, the business datum that is therefore handed down to the second base station not only comprises the data that send to the first base station, also comprises the data that only send to the second base station to use.The second base station sends to self or sends to the first base station can judge described business datum time, and the described signaling data that sends to described the first base station is packaged into descending PS business.

Concrete, the second base station can be according to the resource information in the configuration data of first base station of preserving, the transfer resource that the business datum issuing with the second base station controller takies compares, and judges whether described business datum mails to the first base station, or distributes to the second base station itself and use.

The signaling data that base station was down direction by the descending PS Service recovery of receiving in 1015: the first, sends to subscriber equipment, completes the Signalling exchange of call flow.

In the active call flow process of initiating take the subscriber equipment in community under the first base station, the Signalling exchange of access phase is as example.Up direction, first subscriber equipment needs to send channel request (channel request) signaling to the first base station by Random Access Channel, requires network to provide a SDCCH channel for signaling transmission.Receive after the described channel request signaling of subscriber equipment the first base station, generate a channel request (channel required) signaling, and this signaling data is changed into up PS business, send to data transmission set by eating dishes without rice or wine, be forwarded to the second base station by data transmission set, this up PS business agent's of the second identification of base stations signaling content, parses after described signaling data, sends to the second base station controller.Down direction, the second base station controller is received after this channel request signaling, according to the judgement to existing system Radio Resource, such as, for whether this request is selected a corresponding idle channel and inquires about corresponding ground resource (transmission circuit etc.) to channel activation (channel active) signaling of the first base station transmission and can use, described channel activates signaling and is first issued to the second base station, the second base station by this signaling with mail to other signalings of self or after business datum distinguishes mutually, convert this signaling to descending PS business, send to data transmission set by eating dishes without rice or wine, be forwarded to the first base station by data transmission set, the first base station reduction obtains this channel and activates signaling, and this is responded, return to a channel and activate confirmation (channel active ACK) signaling to the second base station controller, transmitting procedure and channel request signaling are similar, exceed and repeat at this.In access procedure, also comprise assignment immediately (immediate assignment), the refusal of assignment immediately (immediate assignment reject), the signalings such as CM service access request (CM service request), transmitting procedure is distinguished by up-downgoing, similar with above-mentioned transmitting procedure, do not repeat at this.

Further, after Signalling exchange completes, subscriber equipment can carry out voice communication service, and concrete steps can comprise 1016-1022.

The voice data transmission of up direction comprises step 1016-1018.

1016: up direction, subscriber equipment sends speech data to the first base station.
