Abstract: The present invention is a extended range concentric cell base station and a method for extending a cell size or access range without incurring ASIC correlator re-design. This is accomplished with a concentric cell base station design that incorporates multiple timing protocols. The concentric base station has associated a micro cell and a macro cell, wherein the micro and macro cells use a different timing protocol that will cause signals transmitted by mobiles within their respective cells to be received within the confines of search windows associated with the timing protocols.

Abstract: The present invention is a method for performing handoffs in wireless communications systems having extended range concentric cell base station, wherein the concentric cell base station has a micro cell and a macro cell that incorporates multiple timing protocols to extend the base station's access range. In one embodiment, the base station determines whether a handoff is to be performed using absolute path delay information, which will indicate the current and previous positions of a mobile-telephone. If the absolute path delay information indicates that the mobile-telephone is moving between the macro cell and the micro cell, or to a cell associated with another base station, the current base station will instruct the mobile-telephone to perform a handoff to the frequency band associated with the micro cell, macro cell or base station to which the mobile-telephone is traveling towards.

Abstract: A high priority and/or emergency overload access control system treats a wireless unit as a higher priority wireless unit when the wireless unit is attempting to access a wireless communications system with a high priority call, such as an emergency call. For example, the overload access control system can recognize if the wireless unit is attempting to initiate a call to an emergency number. If so, the wireless unit can perform a persistence test as an emergency class (e.g. overload class 10-15) wireless unit in attempting to access the wireless communications system. Thus, the wireless unit will experience an increased probability of passing the persistence test and thereby reducing the persistence delay in attempting to access the wireless communications system with the emergency call.

Abstract: A method for adjusting the power of a probe signal to be transmitted by user equipment to system equipment of a wireless communication system. The power of the probe signal is adjusted based on information received by the user equipment from the system equipment. The information is a local mean of RSSI at the system equipment. The adjusted probe signal is transmitted and thus has an increased likelihood of being detected by the system equipment. Also, the power available for transmitting the probe signal is used more efficiently when the probe signal is adjusted in accordance with the local mean information received by the user equipment from system equipment of the wireless communication system.

Abstract: A method for allocating traffic between multiple carriers in a wireless communications system measures loading on the communication system and selects an appropriate carrier from multiple carriers, based upon the loading measured. A first carrier is selected if the load on the first carrier is lower than or equal to the lowest loading of any supplemental carrier among the multiple carriers. If the load on the first carrier is not lower, then the subscriber may be assigned either to a supplemental carrier or the first carrier. The carrier assignment of the subscriber depends upon a predetermined threshold, which preferably considers actual or estimated differential interference between the first carrier and the supplemental carrier.

Abstract: PURPOSE: A method is provided to control a traffic load by for a user of an existing base station. CONSTITUTION: The control method of a cell traffic load of a base station comprises steps: that a subscriber station obtains an operating code from the base station by receiving a pilot signal from the base station; of defining a pilot signal boundary about the base station; that the subscriber station obtained the pilot signal obtains a traffic channel allocation from the base station by receiving a paging signal from the base station; of monitoring a traffic load state of the base station; of changing the boundary of the valid area of the paging signal inside the pilot signal boundary.

Abstract: A method for determining the reverse link data Rate Limit for mobile stations active on the reverse link of a High Data Rate system is disclosed. In the ideal case, the Rate Limit is based on only the number of mobile stations located in a common sector that are actually active on the reverse link. Currently, the Rate Limit is determined from the total number of mobile stations in a common sector where the total includes mobiles that are transmitting and receiving. Thus, the current method includes mobile stations that are active on the forward link and may not be active on the reverse link. In this invention, a more optimum method of estimating the reverse link loading is obtained from calculations which includes only the mobile stations which are active on the reverse link. An estimate of the reverse link loading of the mobile stations in a common cell is obtained by adding together the data rates of the data sent from each mobile in a common sector during a common frame. This aggregate rate of data during the frame is filtered to minimize irregularities by using the moving average of an infinite impulse response filter and then normalized. The normalized result is a percentage of the maximum achievable aggregate reverse link rate. The final result is compared with a set of threshold values to obtain the maximum Rate Limit that is then set for each mobile station.
