Claims (7)

1. Способ осуществления выделения канала в базовой станции для системы подвижной связи, заключающийся в том, что формируют в системе приемопередатчика базовой станции (ПБС) сообщение об установлении связи после получения запроса на выделение канала для подвижной станции, причем сообщение об установлении связи содержит канальную информацию, указывающую тот код Уолша из 256 кодов Уолша, который должен использоваться для канала, выделяемого данной подвижной станции, и индекс квази-ортогональной функции (КОФ), передают сформированное сообщение об установлении связи в контроллер базовой станции (КБС), формируют в КБС сообщение подтверждения установления связи, подтверждающее относящуюся к выделению канала информацию, включенную в сообщение об установлении связи, передают сформированное сообщение подтверждения установления связи в ПБС и выделяют в ПБС данной подвижной станции канал, подтвержденный КБС, после приема сообщения подтверждения установления связи.1. A method for channel allocation in a base station for a mobile communication system, which method comprises: forming a communication message in a base station transceiver (BSS) system after receiving a channel allocation request for a mobile station, wherein the communication message contains channel information indicating the Walsh code of 256 Walsh codes that should be used for the channel allocated to this mobile station, and the index of the quasi-orthogonal function (COF), transmit the generated message On establishing communication in the base station controller (BSC), a communication confirmation message is generated in the BSC confirming the information related to channel allocation included in the communication establishment message, the generated communication confirmation message is transmitted to the BSS and the channel is allocated to the BSS of this mobile station confirmed by the BSC, after receiving the communication confirmation message. 2. Способ по п. 1, отличающийся тем, что обеспечивают четыре квази-ортогональные функции. 2. The method according to p. 1, characterized in that it provides four quasi-orthogonal functions. 3.

Способ по п. 1, отличающийся тем, что при формировании сообщения об установлении связи определяют, следует ли выполнять маскирование КОФ на канале, выделяемом подвижной станции, если определено, что маскирование КОФ не должно выполняться, определяют канальную информацию, указывающую тот код Уолша из 256 кодов Уолша, который должен использоваться для канала, выделяемого подвижной станции, и устанавливают индекс КОФ на "00", заполняют остальные информационные поля в сообщении об установлении связи и передают сообщение об установлении связи в КБС. 6. The method according to p. 1, characterized in that when generating a communication message, it is determined whether to mask the COF on the channel allocated to the mobile station, if it is determined that the masking of the COF should not be performed, channel information indicating that Walsh code is determined of 256 Walsh codes, which should be used for the channel allocated to the mobile station, and set the COF index to "00", fill in the remaining information fields in the communication message and transmit the communication message to KBS. 7. Способ по п. 1, отличающийся тем, что сообщение об установлении связи является сообщением интерфейса A3, передаваемым, когда получающая базовая станция инициирует или добавляет одно или несколько соединений для пользовательского графика интерфейса A3 в блоке выбора/распределения (БВР) отправляющей базовой станции. 7. The method according to claim 1, characterized in that the communication message is an A3 interface message transmitted when the receiving base station initiates or adds one or more connections for the A3 user interface schedule in the selection / distribution unit (BWR) of the sending base station .
