Abstract
A method and an apparatus provide for controlling a remote unit's requests to access network resources in a wireless communication network. The method and apparatus scale back the frequency with which the remote unit attempts to establish a connection with a base unit, which connection would provide dial tone to a communication device associated with a remote unit. In accordance with the method, with each unsuccessful attempt to establish a connection with the base unit a retry timing interval is extended, thereby throttling back the number of establishment attempts by the remote unit.
Claims7
A method for controlling requests from a wireless communications device to access a wireless network, the method comprising:
- periodically transmitting an access request to a base station wherein the period between transmissions is determined in accordance with a first time interval;
- after n transmissions of the access request, periodically transmitting an access request to the base station wherein the period between transmissions is determined in accordance with a second time interval;
- after m transmissions of access requests, where m>n, systematically increasing a time interval between transmissions of access requests until either a response is received, or the period reaches a maximum value.
In a wireless communication system, a method for emulating requests for dial tone in wireline networks, the method comprising:
- detecting that a wireless communication device goes off-hook;
- transmitting an establishment attempt to a base unit;
- determining whether said establishment attempt is successful during a first time interval and if it is not then transmitting another establishment attempt to the base unit;
- determining whether said another establishment attempt is successful during a second time interval greater than said first time interval;
- if said another establishment attempt is not successful, transmitting yet another establishment attempt to the base unit;
- determining whether said yet another establishment attempt is successful during a third time interval greater than said second time interval;
- and
- if said yet another establishment attempt is unsuccessful, periodically transmitting an establishment attempt to the base unit wherein a period of time between successive attempts is systematically increased until either establishment is successful or the period reaches a maximum value.
A method for conserving bandwidth in a fixed wireless environment that includes a plurality of remote wireless communication devices and a base unit, the method comprising:
- detecting that a wireless communication device goes off-hook;
- transmitting an establishment attempt to a base unit;
- determining whether said establishment attempt is successful during a first time interval and if it is not then transmitting another establishment attempt to the base unit;
- determining whether said another establishment attempt is successful during a second time interval greater than said first time interval;
- if said another establishment attempt is not successful, transmitting yet another establishment to the base unit;
- determining whether said yet another establishment attempt is successful during a third time interval equal to said second time interval;
- and
- if said yet another establishment attempt is unsuccessful periodically transmitting an establishment attempt to the base unit wherein a period of time between successive attempts is systematically increased until either establishment is successful or the period reaches a maximum value.
