  • Patent number: 7596379
    Abstract: The present invention concerns a method for maintaining transparent mode radio bearers in a Radio Access Network (RAN) of a third generation mobile telecommunications network. The method relates to managing the radio resources allocated to a user equipment (UE) in said radio access network (RAN). The method generally comprises communicating a message from a radio resource controller (RRC) of the RAN to the UE where said message is arranged to instruct the UE to transition from a dedicated channel connection state to a lower activity connection state and to store in its memory transparent mode (TM) radio bearer (RB) information associated with said dedicated channel connection state. By storing TM RB information associated with the dedicated channel connection state, the UE can be reconfigured to the dedicated channel connection state without the RAN having to perform a radio bearer setup procedure.

  • Patent number: 7574208
    Abstract: A seamless solution transparently addresses the characteristics of nomadic systems, and enables existing network applications to run reliably in mobile environments. A Mobility Management Server coupled to the mobile network maintains the state of each of any number of Mobile End Systems and handles the complex session management required to maintain persistent connections to the network and to other peer processes. If a Mobile End System becomes unreachable, suspends, or changes network address (e.g., due to roaming from one network interconnect to another), the Mobility Management Server maintains the connection to the associated peer task—allowing the Mobile End System to maintain a continuous connection even though it may temporarily lose contact with its network medium. An interface-based listener uses network point of attachment information supplied by a network interface to determine roaming conditions and to efficiently reestablish connection upon roaming.

  • Patent number: 7492754
    Abstract: A novel and improved method and apparatus, in a WCDMA communication system, for informing a mobile station of a downlink data frame time offset by determining the downlink data frame time offset, and transmitting the downlink data frame time offset via an Active Set Update message transmitted from a cell to mobile station. Once an Active Set Update message is received, the data frame time offset information is provided to a timing block which may determine data frame boundary of each downlink signal. Timing block may then adjust the PN sequence timing corresponding to the downlink signal associated with the data frame time offset such that corresponding data symbols in each data frame are correctly soft combined in a combiner.

  • Patent number: 7460834
    Abstract: A method and apparatus for utilizing a switched beam directional antenna in a wireless transmit/receive unit (WTRU) is disclosed. A wireless communication system includes a serving cell, a neighbor cell and a WTRU. The WTRU is configured to generate and steer a directional beam in a plurality of directions. Once the WTRU registers with the wireless communication system, the WTRU receives messages transmitted by the serving cell. The WTRU measures signal quality of messages received in each of a plurality of predetermined directions while steering the directional beam antenna. The WTRU selects a particular one of the directions having the best signal quality. As the WTRU constantly moves, the WTRU monitors signal quality in the selected direction, and switches to another direction when the signal quality in a current direction drops below a predetermined threshold.

  • Patent number: 7457304
    Abstract: A method for a hybrid service discovery adapting between push-based and pull-based schemes in a mobile ad-hoc network and a system thereof. The method includes periodically transmitting a first control packet for providing service information from a service provider that is capable of providing a service to nodes located in a specified advertisement zone, transmitting a second control packet requesting the service from a service demander to one or more nodes in a network, and transmitting a third control packet including path information of the service provider if at least one of the nodes located within the advertisement zone and the service provider receives the second control packet. The method and the system can reduce the amount of control packet transmission and minimize an end-to-end delay.

  • Patent number: 6914965
    Abstract: An apparatus and method of providing a reliable method of entering command mode and executing modem commands with a modem comprising a wireless communications channel. A wireless communications channel inserted into a standard modem configuration splits the functions of the modem between a mobile unit and a base station. When the system enters command mode, only the base station equipment changes state. The mobile unit continues to operate in the same manner as when the system is in data mode. Any command issued in command mode requiring action from the mobile unit is first sent to the base station. The base station recognizes that the command is intended for the mobile unit and sends a mobile unit-command over an independent private command channel to the mobile unit. The mobile unit constantly monitors the private channel regardless of the state of the system.

  • Patent number: 6389271
    Abstract: Selection of a program in a DAB receiver is facilitated. There are provided a data table 31 containing sets of a service ID and a time data indicating a broadcast time of that program in order of the time as well as a data table 32 containing the service ID in order of receiving frequency of that program. When an operation for selecting a program is performed, it is checked whether or not a data coincident with a service ID of a program of the latest broadcast time among data of the data table 31 is found in the data table 32. As a result of this check, if it is found, a program of that service ID is selected. As a result of the check, if it is not found, the same processing is thereafter repeated to select a program, with a service ID of a program of the next latest broadcast time among data of the data table 31.

  • Patent number: 6324404
    Abstract: A cellular telephone system has call management decisions made based on the exact geographic location of the mobile unit. These call management decisions include billing and taxing decisions, cell site selection, frequency selection and even cellular system selection. The decisions are continuously updated during a call whereby decisions can be made and changed regardless of where a call originated. Cell site location, and even cellular system selection, can be made in a specific manner to best serve the needs of the mobile user, the cellular system as well as the public. It is even possible for a cellular system to locate one or more of its cell sites in the geographic area served by another cellular system. In some cases, cellular systems might even share cell sites.

  • Patent number: 6314292
    Abstract: A method is illustrated for reducing the call setup time of high priority calls such as voice or high speed user generated data without unduly wasting RF frequency resources on non priority calls such as short message calls. This is accomplished by ascertaining the call priority at the base station controller (BSC) level in a GSM system soon after call initiation and immediately changing the channel assignment for use by the remaining signalling type messages to a different operational speed where appropriate. The concept is further extended by supplying the call priority data to a called party's BSC such that all signalling messages after initial contact can be at the operational speed appropriate to the priority of the call.

  • Patent number: 6292662
    Abstract: A method and system for processing telephone calls within a digital wireless telephone system is described. During the initiation of a telephone call from a wireless subscriber unit, it is determined whether the receiving subscriber unit is also part of a digital wireless telephone system that has compatible vocoding capability. If so, vocoded data from the digital wireless telephone system is converted into tones that are introduced into a wire based telephone system for routing to the appropriate receiving digital wireless telephone system. When these tones are received by the receiving digital wireless telephone system, the vocoded data is regenerated based on the tones and then transmitted to the receiving subscriber unit.
