Abstract:
1. A method for accessing a reverse common channel in a wireless network comprising: according to burst data to be sent, a terminal sending a burst data request to a base station in said reverse common channel; according to captured said burst data request, said base station allocating resources to the burst data to be sent in said reverse common channel, and notifying allocated resources to said terminal through a forward common channel; and said terminal using said resources allocated by said base station to send said burst data to said base station in said reverse common channel according to a Hybrid Automatic Repeat Request (HARQ), wherein: said reverse common channel comprises: a first common subchannel and a second common subchannel; said first common subchannel is used for said terminal sending said burst data request to said base station, and said second common subchannel is used for said terminal sending said burst data to said base station by using said resources allocated by said base station in said reverse common channel according to the HARQ; and said burst data request comprises: address information of said terminal, a length of the burst data which is requested to be sent and delay requirement parameters of the burst data which is requested to be sent, and wherein: the step of according to captured said burst data request, said base station allocating resources to the burst data to be sent in said reverse common channel, and notifying allocated resources to said terminal through the forward common channel comprises: a cell busy and idle detecting unit in an allocator in said base station detecting a cell reverse load value in real time, and according to obtained said cell reverse load value, comparing with an overload threshold to obtain a ratio of power of an access channel data part to power of a reverse pilot part in a slot in said second common subchannel, and according to this ratio, obtaining a transmission rate used in said second common subchannel; and then according to this transmission rate and the length of the burst data which is requested to be sent included in said burst data request, calculating the number of access channel data frames required by said burst data; and then according to the number of said access channel data frames and a deadline of the delay requirement parameters of the burst data which is requested to be sent in said burst data request, obtaining a slot resource arrangement format in each said access channel data frame carrying said burst data; at the same time, said allocator in said base station obtaining a power adjusting value between slots in said access channel data frame by a working frequency band of said base station and said delay requirement parameters of the burst data which is requested to be sent included in said burst data request; said allocator in said base station arranging obtained “transmission rate used in said second common subchannel”, “slot resource arrangement format in each said access channel data frame carrying said burst data” and “power adjusting value between slots in said access channel data frame” into a confirmation message of said burst data request, and sending the confirmation message of the burst data request to said terminal through said forward common channel according to the “address information of said terminal” included in said burst data request.
