Abstract: A method of wireless communication. The method includes the step of broadcasting a message, such as channel list message, for example. The broadcasting message lists each available carrier for each available frequency band in the wireless communication spectrum—e.g., 400 MHz and about 2100 MHz. Each available carrier listed within the message may correspond with at least one cell of a coverage area. Moreover, each broadcast message comprises at least one occurrence for each available carrier. Each available carrier may also be repeated within the message a number of times corresponding to a carrier weighting. This carrier weighting in turn corresponds with a traffic load. Alternatively, the method may also include the step of repeating the broadcast of the message a number of times, wherein the number corresponds to a carrier weighting associated with the traffic load.

Abstract: Multiple carriers are used to provide access to a wireless communication system. A first carrier transmits synchronization messages in accordance with the IS-95B standard (communication protocol revision 5). The synchronization message directs mobiles attempting to access the network to a paging channel on the first carrier. The paging channel enables mobiles conforming to a standard of IS-2000 revision 0 or older to access the wireless network. The paging channel also includes an extended global service redirection message (EGSRM) that instructs mobiles conforming to the IS-2000 revision A standard (communication protocol revision 7) to use a synchronization channel on a second carrier for reception of an IS-2000 revision A synchronization message. The IS-2000 revision A (communication protocol revision 7) synchronization message instructs the mobile to access the wireless communication network using a BCCH and/or FCCCH on the second carrier, or using a BCCH and/or FCCCH on the first carrier.

Abstract: A flexible synchronization message format permits older mobiles as well as newer mobiles to access a wireless communication network. Three types of synchronization messages are time division multiplexed unto the synchronization channel. A first message is interpreted by the newer mobiles and some older mobiles. A second message is interpreted by a second set of older mobiles and a third message is interpreted by a final set of older mobiles. The second and third type of messages are formatted so that they will be ignored by the newer mobiles so that the newer mobiles will not follow instructions associated with older standards and, thereby, not take advantage of options offered under the newer standards. In another embodiment, the frequency with which each of the three messages is transmitted is varied to provide preferential treatment to a particular message type.

Abstract: The present invention, in illustrative embodiments, implements systems and methods for adjusting the timing of access requests in mobile communications systems, such as IS-95-A mobile telephone systems, to reduce the likelihood of request collisions—especially during periods of very high calling rates. These embodiments employ measurements of access channel occupancy, as well as system operator inputs, to develop thresholds and parameter translations at a base station. Execution of control algorithms at a base station advantageously yields modified persistence test parameters sent to mobile stations. When overload conditions are present, these modified parameters cause the mobile stations to experience variable delays through judicious control of persistence testing at the mobile stations.

Abstract: A method of allocating CDMA codes from a set of the same is provided for use in connection with a wireless network. The method includes, after identifying a desired size of the code to be allocated, determining if there exists a code of the desired size whose sibling is unavailable. If such a code is found, then it is allocated. Otherwise, it is determined if there exists a code of smaller than the desired size whose sibling is unavailable. When such a code (i.e., a code of smaller than the desired size whose sibling is unavailable) is found, a descendant thereof which has the desired size is allocated.

Abstract: A method and apparatus for transmitting a burst of data over a supplemental channel on just one leg of a handoff by changing at least one of the parameters of the data to be transmitted over the supplemental channel as a function of the future and/or current characteristics of the communication link of the leg(s) of the handoff. This controlled parameters of the data can include the maximum allowed burst duration, and the type and/or amount of error coding of the data. The data is then transmitted over just one leg of handoff using the parameter. By changing the parameters of the data, the data may still be acceptably received at the mobile terminal over just one leg of the soft handoff even when the strength of the pilot signal used for the supplemental channel changes significantly. The invention thus, advantageously, delays or possibly obviates the need to establish a supplemental channel over additional legs of the soft handoff.

Abstract: Disclosed is a method for utilizing SCH resources more efficiently for supplemental channels (SCH) by minimizing gaps between data bursts due to overhead delays. Such gaps are minimized using a supplemental channel sharing algorithm to prospectively assign SCH resources supporting existing SCHs and to schedule future issuance of DNRs such that currently unavailable SCH resources may be prospectively assigned based on states of the SCH resources, wherein an existing SCH is a SCH over which a data burst is currently being transmitted.
