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: An apparatus and method for adaptive broadcast transmission. A broadcast transmission can be received. Insufficiency of a broadcast channel quality can be determined. A negative acknowledgement signal can be sent on a common uplink channel in response to determining the broadcast channel quality is insufficient. The negative acknowledgement signal can be received on the common uplink channel at another location, the negative acknowledgement signal indicating broadcast channel quality is insufficient. The broadcast channel quality can be adjusted in response to receiving the negative acknowledgement signal.

Abstract: A method and apparatus for broadcast services transmission and reception. Reception of a broadcast multicast transmission is requested. Preliminary short time updated key information is transmitted or received prior to transmitting or receiving a broadcast subscription key for the requested broadcast services transmission. An encrypted broadcast services transmission is transmitted or received. The encrypted broadcast services transmission is encrypted or decrypted using the preliminary short time updated key information.

Abstract: Various embodiments are described herein to address the need for reducing call setup delays with respect to supplemental channels. Modifications to channel assignment messaging (104), such as an enhanced ECAM, and service connection messaging (108), such as an enhanced SCM, are described. These modifications enable the assignment of SCHs (110) earlier in the call setup sequence. In addition, embodiments for determining and anticipating when such modified messaging may effectively speed the transfer of data (including VOIP) between a BS (201) and an MS (210) are described.

Abstract: The need to reduce the cost associated with signaling mobiles (120) across multiple cells (101-108) is addressed by embodiments of the present invention. A targeted MS is initially paged only in those cells in which the paging channel loading level is below a particular paging threshold. Similarly for short messaging, the RAN transmits the short messaging to the MS only in those cells in which the paging channel loading level is below a short messaging threshold. Therefore, the MS can be signaled in under-loaded cells first, were the effect on system capacity and performance is negligible. When successful, the MS signaling is achieved at a lower cost to the system than when loaded cells are involved.

Abstract: In general, paging-related delays are reduced by empowering an idle mobile (120) to initiate a transition to semi-dormant, unslotted mode, and/or RSCI modes, based on triggers (304) known to the MS. This is an efficient manner (in terms of both RF and battery-life cost considerations) in which to use semi-dormant and RSCI modes (306). If the MS (120) is able to anticipate a paging channel (PCH) message (for example, after sending or receiving an SMS or presence update), then the MS can intelligently reduce its slot cycle index for a short period of time, sacrificing a small amount of battery life, when the R-SCI is most likely to deliver improved service. Moreover, if the MS is low mobility (i.e. low idle handoff rate), then the MS can transition to a semi-dormant mode with very little cost, since it will not need to send many radio environment reports.

Abstract: The need to decrease paging-related delays in wireless systems (100) is addressed by embodiments herein. A RAN (201) anticipates that an MS (120) is likely to be a target of communication not yet initiated. In one embodiment, a traffic channel is assigned to the MS, when a loading level of a serving cell of the MS is below an assignment threshold. This avoids paging-related delays for the MS should the MS become a target of communication. In another embodiment, the MS is signaled to transition to at least one operational mode in which paging-related delays for the MS are reduced. Such modes include a semi-dormant mode, an unslotted mode, a control hold mode, a speculative scanning mode, and a reduced slot cycle index (RSCI) mode. This allows the MS to begin participating in communication more quickly than it otherwise would, should communication targeting the MS be initiated.

Abstract: To address the need for a dispatch mobile (303, 305, 307) to more quickly make a call, in the preferred embodiment of the present invention those remote units operating in a dispatch mode (303, 305, 307) will receive a first slot cycle, while those remote units not operating in a dispatch mode (302, 304, 306, 308) will receive a second slot cycle. The second slot cycle is greater than the first slot cycle, so that those remote units operating in dispatch mode (303, 305, 307) will “wake up” during the slot cycle normally utilized for interconnect calls. Because shorter slot cycles are utilized for remote units operating in dispatch mode (303, 305, 307), the time it takes to make a dispatch call is greatly reduced. Additionally the minimum slot cycle duration typically used for standard calls remains unchanged, greatly conserving battery life.
