Claims (11)

1. Способ выполнения мобильной станцией процедуры произвольного доступа в системе мобильной связи, заключающийся в том, что получают синхронизацию с требуемой базовой станцией, выбирают шаблон подписи из множества шаблонов подписей, используя шаблон подписи формируют кадр запроса доступа, расширяют кадр запроса доступа с использованием расширительного кода и передают на упомянутую требуемую базовую станцию кадр запроса доступа, расширенный на этапе расширения.1. A method for a mobile station to perform a random access procedure in a mobile communication system, which consists in obtaining synchronization with a desired base station, selecting a signature template from a plurality of signature templates, using the signature template, generating an access request frame, expanding the access request frame using an extension code and transmitting, to said desired base station, an access request frame extended in an extension step. 2. Способ по п. 1, отличающийся тем, что при выборе шаблона подписи этот выбор выполняют случайным образом из внутренней памяти мобильной станции. 2. The method according to p. 1, characterized in that when choosing a signature template, this selection is performed randomly from the internal memory of the mobile station. 3. Способ по п. 1, отличающийся тем, что при формировании кадра запроса доступа, используя шаблон подписи, шаблон подписи вводят в заголовок кадра запроса доступа. 3. The method according to claim 1, characterized in that when generating the access request frame using the signature template, the signature template is entered in the header of the access request frame. 4. Способ демодулирования базовой станцией множества запросов произвольного доступа, заключающийся в том, что принимают первый запрос произвольного доступа, причем этот первый запрос произвольного доступа содержит первый шаблон подписи, подают первый запрос произвольного доступа на по меньшей мере один согласованный фильтр для того, чтобы получить суженный результат, используя множество различных шаблонов подписей накапливают суженный результат для выработки множества результатов накопления и обнаруживают по меньшей мере один пиковый сигнал во множестве результатов накопления. 4. A method for a base station to demodulate a plurality of random access requests, comprising: receiving a first random access request, this first random access request containing a first signature template, submitting a first random access request to at least one matched filter in order to obtain narrowed result, using many different signature templates, accumulate narrowed result to produce many accumulation results and detect at least one picot first signal in a plurality of accumulation results. 5.

Способ по п. 8, отличающийся тем, что первый пиковый сигнал и второй пиковый сигнал обнаруживают во множестве результатов накопления по существу одновременно. 10. The method of claim 8, wherein the first peak signal and the second peak signal are detected in the plurality of accumulation results substantially simultaneously. 11. Способ по п. 8, отличающийся тем, что первый запрос произвольного доступа и второй запрос произвольного доступа разграничивают на основании, по меньшей мере частично, по меньшей мере первого пикового сигнала и второго пикового сигнала. 11. The method of claim 8, wherein the first random access request and the second random access request are delimited based at least in part on at least the first peak signal and the second peak signal.
