Abstract: A direct sequence code-division multiple access (DS CDMA) communication system schedules conveyance of blocks (400) of information such that the blocks arrive at a base-site (130) just-in-time for transmission during a discrete frame (301-305) of an air-interface. The DS CDMA communication system implements both circuit switching and packet switching approaches to provide trunking efficiencies while balancing between system loading constraints and time delay of blocks (400) during conveyance.

Abstract: Dans un réseau cellulaire AMRT, un mécanisme qui permet de sauter entre des fréquences porteuses partagées comprend l'attribution bloc par bloc dans un diamètre de réutilisation d'au moins une porteuse parmi un ensemble de porteuses à blocs réparties par multiplexage dans le temps à une zone de couverture (AI) pendant certaines tranches temporelles et l'attribution bloc par bloc dans le diamètre de réutilisation de ladite porteuse de la porteuse à blocs répartis à une autre zone de couverture (AI) pendant d'autres tranches temporelles qui ne chevauchent pas les premières, en synchronisme, de manière à ne pas provoquer des interférences avec la même porteuse réutilisée à proximité de ladite zone de couverture, ce qui permet d'obtenir les avantages des sauts entres les fréquences. En d'autres termes, le mécanisme comprend l'attribution à un certain moment, dans un diamètre de réutilisation d'au moins une porteuse parmi une pluralité de porteuses à sauts entre fréquences à une zone de couverture (AI), alors qu'au même moment, dans ce même diamètre de réutilisation de la porteuse, une autre porteuse parmi une pluralité de porteuses à sauts entre fréquences est attribuée à une autre zone de couverture (AI), en synchronisme avec toute autre réutilisation de la porteuse à proximité de la zone de couverture. Les porteuses de commande et d'accès peuvent également être incluses dans le groupe de fréquences à sauts entre fréquences, de sorte que certaines tranches temporelles sont sautées dans une séquence différente des autres. L'ensemble d porteuses à sauts entre fréquences est en outre réparti parmi des sites rapprochés en groupes de porteuses à sauts entre fréquences, réduisant la synchronisation requise dans le système. Afin de résoudre le problème de proximité/éloignement, les tranches temporelles de multiplexage temporel à la limite des sauts entre fréquences sont de préférence attribuées à des utilisateurs mobiles moins éloignés.

Abstract: A method (400) for establishing a first communication link between a communications network (105) and a network node (115) in accordance with a first wireless communications protocol. The method also can include evaluating a signal parameter for a signal transmitted between a station (110) and the network node. In response to the channel quality exceeding a threshold, the station can be signaled to establish a second communication link with the network node in accordance with a second wireless communications protocol. The network node can bridge communications between the station and the communications network.

Abstract: A wireless mobile terminal (10) and method for utilizing digital broadcast content records (204) selected digital broadcast content as received, for example, by a digital broadcast receiver (16) and provides editing of the selected digital broadcast content based on digital rights management data to generate customized clips of information. The selected digital broadcast content is edited (206) to produce mobile terminal edited digital broadcast content that may be, for example, distributed (208) by the mobile terminal to a plurality of peer devices. A broadcast content editor (24) allows for the editing of clips of content wherein the edited clips are then stored in memory as recorded clips for distribution by the mobile terminal. In another embodiment, a network element is remotely controlled by the mobile terminal to effect editing through the mobile terminal at the network element.

Abstract: A method and apparatus for mitigating the impact of lost data due to cell reselection for mobile stations operating in packet data transfer mode is described. A mobile station may perform cell reselection 2 to 4 times per minute when located in an urban area, even if the mobile station remains stationary. A mobile station moving through a communications network (100) may cross over various cell and routing area boundaries. Further, a mobile station operating in push-to-talk mode may lose up to 8 seconds of data when reselecting a cell in a new routing area. A serving cell transmits an information element (301, 303, 305) in which the mobile station is informed whether cells in its neighbor list are in the same routing area as its serving cell. If the radio link to the serving cell is acceptable then the mobile station avoids reselection to cells outside its serving cell routing area.

Abstract: Audio degradation is minimized in scenarios where tandem coding occurs. One such scenario is in the environment of voice mail service. Characteristics of an audio information signal are determined, and the signal is classified (303) as to whether further coding (306) should be performed and, if so, which rate/type of coding should be performed. Characteristics of the audio signal which are determined are, inter alia, quality characteristics, rate of previous coding, type of previous coding and the source of previous coding of the audio information signal. The source of previous coding determined may further include, inter alia, an analog network, a digital network, a PSTN or a wireless communication system. Based on this information, the voice mail service will either choose not to further code the audio information signal or code the audio information signal with the best coding algorithm available.

Abstract: Different orthogonal codes (Wx, Wy) are used to spread common pilot channels (PilotA) intended for transmission to a particular mobile station (106) within a coverage area (sector A) to implement forward link transmit diversity. By implementing separate, different orthogonal codes (Wx, Wy) for each pilot channel (PilotA), the pilot signals transmitted via antennas (218, 222) to a common coverage area (sector A) are orthogonal to one another and thus do not degrade system performance. Additionally, the use of different orthogonal codes (Wx, Wy) for each pilot channel (PilotA) allows the mobile station (106) to discern which pilot channel spread with a different orthogonal code includes corresponding traffic channel (TCH) information. This allows forward link transmit diversity to be enabled/disabled based on conditions associated with the environment, the communications channel, etc. without a complete loss of information as seen by the mobile station (106).

Abstract: Orthogonal transmit diversity is implemented by employing a data splitter (803) to subdivide channel information (801) into at least a first portion of bits (802) and a second portion of bits (804). Each portion is spread with its own Walsh code for eventual transmission to a mobile station via a predetermined carrier frequency. When the number of bits in the first and second portion (802, 804) are small, separate Walsh codes are used to maintain orthogonality. When the number of bits in the first and second portion (802, 804) are relatively large, a time-division multiplex transmission is used to maintain orthogonality. A controller (809) controls the subdivision of the channel information and also an interleaver (308) to further enhance the effects of the diversity transmission. Control information related to the subdivision is transmitted to the mobile station so the channel information can be accurately reconstructed prior to decoding.

Abstract: A subscriber's signal (117) is removed from a composite signal (120) received in a serving base station (100), where the subscriber (113) is not in communication with the serving base station (100). The subscriber's signal (117) is removed from the composite signal (120) by receiving information regarding potential interferers in communication with the non-serving base stations (403). Next, a most reliable signal is determined from the potential interferers in communication with non-serving base stations (405). The most reliable signal is then removed from the composite signal (407).
