Abstract:
Modulation codes for code division multiple access (CDMA) cellular communications systems that are mutually orthogonal may be generated as a sequence of Walsh codes. A method of assigning Walsh codes includes the steps of ( 404 ) receiving as input a status vector ( 200 ) for a Walsh code system of length 2 n and a selected Walsh code length j=2 n-k ; ( 406 )-( 418 ) creating a new status vector for a selected Walsh code length of j from the status vector; ( 416 ) creating a search mask for the selected Walsh code length j; ( 418 ) creating a search sequence for the selected Walsh code length j; and ( 434 )-( 442 ) searching the search sequence for the next available Walsh code. The status vector is updated ( 500 ) to track the assignment and release of each Walsh code of each Walsh code length in the Walsh code system.

Abstract:
The present invention relates to a method and a system for handling one or more soft handoff (SHO) requests from one or more mobile stations (105) in a wireless communication system (101). The method comprises determining a set of parameters corresponding to each SHO request corresponding to each mobile station. The method further comprises processing each SHO request corresponding to each mobile station based on the set of parameters corresponding to each SHO request.
Abstract:
Channel assignment is performed by utilizing a base station controller (BSC) or a base station depending upon a mobile unit's RF environment and/or the type of call being made. By performing call setup in this manner, mobiles that access with no soft handoff requirement (approximately 50% of mobile in IS-2000 systems) will have faster setup times.
Abstract:
A method is provided for transferring user identities between one CDMA wireless communication device (120) and another in a wireless CDMA communication system (100) having a network system controller (140). The network controller (140) receives an activation command from a wireless communication device (120), the activation command including identification information identifying the activating wireless communication device (404). Next, the network controller determines whether the activating wireless communication device is a transferred identity wireless communication device in response to the identification information (424). The network controller then activates the activating wireless communication device with a transferred identity (436) if the activating wireless communication device is determined to be a transferred identity wireless communication device (424).
Abstract:
The need for reducing the time required for call setup in a wireless communication system (100) is addressed herein. A base station (BS 104) sends a channel assignment message to a mobile station (MS 102) and performs traffic channel initialization procedures with the MS. After completing the traffic channel initialization procedures, the BS sends a base station acknowledgment message to the MS and proceeds to transmit signaling to the MS without waiting to receive an MS acknowledgment in response to the base station acknowledgment message. Thus, the time normally taken to receive the MS acknowledgment is saved and call setup time reduced.
Abstract:
A technique for focusing a digital camera is described that includes pre-storing 200 at least one specific image object, such as a known face or landmark, activating 202 the camera to obtain an image, analyzing 204 objects in the image, comparing 206 the objects in the image against the at least one specific image object, and determining 208 if there is a match between at least one object in the image and at least one specific image object. If a match is found, the camera is focused 212, 214, 216, 218 on the matched object and the image is captured 220.
Abstract:
A method (400) and corresponding data processing system (209) of detecting cloned or duplicated communication units based on received signals is described. The method comprise receiving a signal (403) comprising a sequence of data symbols; and determining (405) whether the signal originated from a plurality of communication units based on a parameter, such as power or quality level of a group of the data symbols.
