The present invention relates to communication technology, more precisely to a method and system attenuation between base stations and improve the quality of the connection in failover mode. Background of invention In an emergency, when there is a failure of the communication channel between the base transceiver station and base station controller or a communication channel between the base station controller and the network side, or in the absence of a configured channel, the base station goes into failover mode. For example, multiple access code division multiplexing (CDMA, English - Code Division Multiple Access) is a system with its own interference, in which one person causes harm to the other party, and each cell also may cause harmful interference to other cells, especially for neighboring cells using the same carrier. The failure of the communication channel between running in failover mode the base station and the network side does not support transfer service. Because in the overlap zone, operating in failover mode base station and other base stations use the same carrier frequency channel between the frames easily distorted. the moreover, as for the whole communication system, the frequent transfer of the terminal connection state eventually leads to rupture of the connection, whereas the transfer of the terminal in the idle state of the base station in failover mode causes the terminal receives the signal, but not able to make the connection. The prior art is not known to effectively address the problems of interference between base stations in failover mode and ensure a quality connection for a subscriber in noise conditions. Summary of the invention To overcome these shortcomings in the invention proposed a method and system for attenuating interference between base stations in failover mode, which is able to reduce interference from running in failover mode the base station to the neighboring base stations and to improve the quality of the connection for the subscriber. To achieve the stated purpose in the invention proposed the following technical solution. In the invention proposed a method of mitigating interference between base stations in failover mode, in which the subsystem of the base station changes the carrier frequency of the channel, if it is determined that the used communication channel is in failover mode. Subsystem base station may set the e l e C what used communication channel is in failover mode, one or more of the following ways: the transceiver base station periodically determines the state of the communication channel between the base transceiver station and base station controller, the transceiver base station determines the state of the communication channel between the base transceiver station and base station controller in case of unsuccessful attempts to send the message to the base station controller, the transceiver base station determines the state of the communication channel between the base transceiver station and base station controller in the case of waiting for message transmission to the base station controller over a set time, and the controller of the base station informs the base transceiver station about the failure of the communication channel in the event of a failure of the communication channel between the base station controller and the network side. The carrier frequency of the channel is pre-set in accordance with the state of the network planning, and at the phase change of the carrier frequency of the channel subsystem, the base station may be, in particular, stipulate the following: subsystem base station automatically changes the carrier frequency of the channel used by all cells of the base station.

The method may additionally include the following: subsystem base station on the direct channel personal call sends the mobile station a message containing information about the new carrier frequency channel, the mobile station moves to a new carrier frequency of the channel. Phase transition of a mobile station to a new carrier frequency channel can, in particular, to include the following: mobile station by comparing the sequence numbers of configuration messages contained in the message, and the sequence number of the message with the list of channels stored in the mobile station, determines that the service message updated the mobile station updates the stored communicated to the e list sequence number in accordance with the configuration sequence number of the message, contained in the message, if the subsystem base station supports the transmission of messages with an expanded list of the neighboring base stations and messages with an expanded list of channels, the mobile station updates the relevant information, the mobile station determines the carrier frequency of the channel to channel personal call to the mobile station using the hash algorithm, and the mobile station compares the carrier frequency of the channel, calculated using a hash algorithm and a previously captured the carrier frequency of the channel and moves to a new carrier frequency channel, if the change occurred. System attenuation between base stations in failover mode includes a base station subsystem, which is configured to change the carrier frequency of the channel, if it is determined that the used communication channel is in failover mode. The stage at which the subsystem base station establishes that the communication channel is in failover mode, may include one or more of the following: the transceiver base station periodically determines the state of the communication channel between the base transceiver station and base station controller, the transceiver base station determines the state of the communication channel between the base transceiver station and base station controller in case of unsuccessful attempts to send the message to the base station controller, in the case of waiting for the message transmission controller base station over the selected time, the transceiver of the base station determines the state of the communication channel between the base transceiver station and base station controller, and in the event of a failure of the communication channel between the base station controller and the network side of the controller, the base station informs the base transceiver station about the failure of the communication channel.

In the invention, a method for improving the quality of connection in failover mode, allow us to reduce interference to neighboring base stations without compromising the quality of the connection of the neighboring base station due to the fact that the base station automatically ISM which consists of the carrier frequency channel when moving in failover mode, in the zone of overlap is running in failover mode base station and another base station uses different carrier frequencies of the channel. If you take the CDMA system, the method includes the following stages, which are: first, the base station subsystem goes into failover mode, if it is determined that the communication channel is in failover mode, after migrating to a failover mode subsystem base station automatically changes the carrier frequency of the channel and uses the new carrier frequency channel, thereby attenuated resulting in a total frequency interference to a neighboring base station, after changing the carrier frequency of the channel base station updates and transmits the service message, the CDMA message with the list of channels contains a new carrier frequency channel, and mobile station recalculates captured the carrier frequency of the channel and captures a new carrier frequency channel, if it is determined that the service message is updated. Through the above steps as a subsystem running in failover mode base station and the mobile station use the new carrier frequency channel, thereby attenuated resulting in a total frequency interference from running in failover mode baseballstyle for the neighboring base station, and thereby can effectively increase the quality of the connection for the subscriber.
