Assignee:

Qualcomm, Incorporated - San Diego CA

International Classification:

H04B 700

US Classification:

455432

Abstract:

A subscriber unit that supports more than one voice service option and selects the appropriate voice service option when originating and receiving a call. The subscriber unit includes a memory to store parameter values, including a first voice service option parameter value and a second voice service option parameter value. The subscriber unit also includes a means for determining whether the subscriber unit is within a home system or is roaming, and a selecting means for selecting from among at least a first voice service option corresponding to the first voice service option parameter value and a second voice service option corresponding to the second voice service option parameter value. The selecting means selects the first voice service option if the subscriber unit is within the home system, and selects the second voice service option if the subscriber is roaming.

US Classification:

455434, 455436, 455515, 370335

Abstract:

A method and apparatus for generating an autonomous Pilot Strength Measurement Message (PSMM) by a mobile station traveling in a multi-carrier wireless communication system. In a multi-carrier system, the mobile station receives the pilot channel of a base station on multiple carrier frequencies simultaneously. Fading may vary from carrier frequency to carrier frequency. New pilot strength definitions are used by the mobile station in a set of rules transmitted by the base station. The set of rules determines autonomous generation and transmission of PSMMs by the mobile station upon detection of pilots.

Abstract:

A method and system for a handoff in a broadcast communication system is disclosed. A subscriber assisted handoff is impractical in a broadcast communication system due to e. g. , a high signaling load, a difficulty to synchronize the broadcast transmission. On the other hand, the small number of broadcast channels enables the subscriber station to perform the handoff autonomously. To streamline the autonomous handoff decision process, several distinct sets of pilot identifiers and rules for transitioning among the sets are defined. To fully integrate broadcast services with the services provided by the cellular telephone systems in a subscriber environment, a methods for various handoff scenarios are analyzed.

US Classification:

455574, 4553431, 455458, 455515

Abstract:

A method and system are provided that allow a mobile communications service provider to broadcast messages using more than one broadcast channel protocol, such that only the mobile stations designed to receive broadcast messages transmitted under each protocol are woken up to monitor their respective broadcast channel slots, thus saving battery life in mobile stations designed to receive broadcast messages transmitted using other broadcast channel protocols.

Abstract:

An apparatus and method for communications of scheduling information of reverse link transmissions are disclosed. A base station controller determines scheduling of a reverse link supplemental channel transmission for a mobile station in a communication system ( ). The base station controller groups the mobile station in a group of mobile stations and assigns a forward link channel assignment channel to the group of mobile stations. A transceiver ( ) incorporates information relating to the determined scheduling in the assigned forward link common assignment channel and transmits the assigned forward link common assignment channel to the mobile station for scheduling the reverse link supplemental channel transmission. The mobile station receives the assigned forward link common assignment channel. The mobile station schedules transmission of the reverse link supplemental channel transmission in accordance with the determined scheduling and transmits the reverse link supplemental channel in accordance with the determined scheduling.

Abstract:

Method and apparatus for pseudo-synchronized paging to a mobile station in a wireless communication system. A number of paging repetitions is assigned, wherein a quick page message is repeatedly sent to a target mobile station for the number of paging repetitions. The number of paging repetitions is part of a paging instruction from a base station controller to a base station. The pseudo-synchronized method is used when the target mobile station is soft handoff.
