Access retry method for shared channel wireless communications links

In a wireless network with remote stations that use a collision oriented multiple access scheme to access a base station, a system to enable the base station to adaptively provide additional channels to the remote stations during an interval of high usage, comprising:

• means for counting a number of retries attempted by a remote station to access the base station, as a count value;
• means for inserting said count value in a retry count field of an access request message;
• means for transmitting said access request message to the base station;
• and
• means for adaptively providing with the base station additional channels to the remote station, depending on said number of retries attempted by said remote station to access to said base station.

In a network with client stations that use a collision oriented multiple access scheme to access a server station, a method to enable the server station to adaptively provide additional channels to the client stations during an interval of high usage, comprising:

• counting a number of retries attempted by a client station to access the server station, as a count value;
• inserting said count value in a retry count field of an access request message;
• transmitting said access request message to the server station;
• and
• adaptively providing with the server station additional channels to the client station, depending on said number of retries attempted by said client station to access to said server station.

• counting a number of retries attempted by a remote station to access the base station, as a count value;
• inserting said count value in a retry count field of an access request message;
• transmitting said access request message to the base station;
• receiving an indication from the base station that additional channels are available to the remote station, in response to said count value;
• and
• transmitting messages from said remote station to said base station using said additional channels.

In a network including a plurality of remote stations that use a collision oriented multiple access scheme to gain access to a base station, a method at the base station comprising:

• receiving at the base station an access request message from a remote station after at least one retry attempt by the remote station, the message including a retry count field of the number of attempted retries;
• stripping off the retry count field from the access request message at the base station;
• running a channel allocation program at the base station that adaptively provides additional channels to the remote station, depending on the number of retries the remote station attempted to successfully transmit the access request message;
• maintaining an allocation table at the base station that relates the retry count value extracted from the retry field, to a corresponding channel capacity required for a given probability that an access request will be successful on a first try;
• and
• providing additional channels to the remote station by said base station, in response to the retry count value extracted from the retry field exceeding a given threshold;
• whereby the base station has accurate information about the reduced performance that the remote stations suffer during an interval of high usage, to enable the base station to adaptively provide additional channels to the remote stations.

In a network including a plurality of stations that use a multiple access scheme to gain access to another station, a method comprising:

• receiving at a first station an access request message from a second station after at least one retry attempt by the second station, the message including a retry count value of the number of attempted retries;
• relating the retry count value to a corresponding channel capacity required for a given probability that an access request will be successful on a first try;
• and
• adaptively providing additional channels to the second station, depending on the number of retries the second station attempted to successfully transmit the access request message, in response to the retry count value exceeding a given threshold.
