摘要： An exemplary method for selecting one of a plurality of systems on a multi-mode device capable of communicating on a first air interface technology and a second air interface technology is disclosed. Initially, a carrier input associated with one of the first and second air interface technologies is received. The carrier input typically defines at least one system selection event. Next, a first network acquisition attempt of the other one of the first and second air interface technologies is triggered responsive to the system selection event. The results of the first network acquisition attempt are determined and stored, and subsequently used for subsequent system selection determinations between the first and second air interface technologies.

摘要： To improve WWAN coverage, an access node broadcasts overhead messages on a first channel covering a first channel environment and a second channel covering a second channel environment within a coverage region. The overhead messages carry network overhead parameters for allowing wireless mobile devices to acquire and maintain traffic channels within the cellular system. The overhead message channels are configured so that a user perceives uninterrupted wireless services while moving through different channel environments in the coverage region. In one embodiment, the overhead message channels are separate physical channels configured with different broadcast parameters to provide coverage in different environments. In another embodiment, the overhead parameter information is segregated into base and extended components that are encoded and layer modulated onto separate logical channels. Using layered modulation, wireless mobile devices can receive base components in poor coverage regions. The base components include overhead parameters for acquiring a WWAN channel.

摘要： A system and method for paging wireless mobile devices selectively varies the effective modulation order of a paging channel to achieve improved coverage in a wireless wide area network (WWAN) cell. In one embodiment, the paging channel modulation order is selected based on a measured signal strength and/or common channel error rate. The selected modulation order is directly related to the quality of the channel environment. In another embodiment, a page message is segregated into base and extended components that are layer modulated. With layered modulation, wireless mobile devices in good coverage regions can successfully demodulate both the base and extended components to recover the entire page message. Wireless mobile devices in poor coverage regions can successfully demodulate the base component of the page message, and then request that the extended component of the page message be re-broadcast as a base component to thereby recover the entire page message.

摘要： In response to detecting a call attempt for a priority call on the originating wireless network by an initiating access terminal, at least one active call having a priority level less than the priority call is transferred to an alternate technology wireless network. If a call attempt is placed when a transfer threshold has been exceeded, candidate transferring terminals are identified based on multi-mode capabilities and network conditions. One or more of the candidate transferring terminals engaged in calls that have a priority level less than the priority call are transferred from the originating wireless network to the alternate technology wireless network when the transfer threshold is exceeded.

摘要： A common group cell identifier is transmitted by adjacent base stations. Handover processing is minimized for mobile relays traveling along a predetermined path that traverses the adjacent base stations. A first base station along the path transmits a group cell identifier and a first single cell identifier within a first service area. An adjacent base station transmits the group cell identifier and a second single cell identifier within a second service area that at least partially overlaps the first service area. The mobile relay monitors the group cell identifier in certain situations and only performs a handover when the group cell identifier changes. As a result, no handovers are initiated as the mobile relay travels down the path since the group cell identifier transmitted by the base stations along the path are the same.

摘要： An apparatus, system, and method for managing geographical location information of a portable communication device by determining and storing the geographic location information while registered on a cellular communication system in response to detecting an available wireless local area network (WLAN) system. When the portable communication device is communicating on the cellular communication system and a WLAN access point is detected, a location determination procedure is performed and the resulting geographical location information is stored at the portable communication device. When the portable communication device is communicating with a wireless access point of a WLAN system, and a second access point is detected, the portable communication device registers to the cellular communication network, if not already registered, and performs the geographical location determination procedure. Geographical location information is transmitted to a public safety answering point (PSAP) or network entity when an emergency call is executed.

摘要： In a wireless communication system, data is encoded by packet indifferent (PI) coding and some packets are transmitted omnidirectionally while supplemental packets are transmitted directionally to a user with a poor air link. PI encoding is defined herein as encoding in which the source data can be recovered from any K of the encoded packets, regardless of which of the encoded packets are received, where K=N+A. N is equal to the number of packets in the source data and A is the number of additional packets required due to the PI encoding. A subset of M data packets can be sent to one or many users from an omnidirectional antenna, where M is greater than or equal to K. If less than K data packets are received by at least one user, then the data block is not successfully received by that user. A number R of supplemental packets can be sent to users that did not receive K data packets successfully. The supplemental packets can be sent by a directional antenna to the specific user or users that did not receive K data packets.

摘要： A multi-mode receiver and methods are provided, which use blind source separation (BSS) analysis to distinguish the various wireless communication signals from each other. Specifically, different signal types can be identified by BSS. The different signal types can be in overlapping frequencies or they can be in completely different frequencies. The BSS analysis may use center or carrier frequency, bandwidth, modulation scheme, access scheme, or wireless communication resources as an input to assist in the BSS.
