Abstract: A method for reducing interference in a wireless system, and a system for performing the method. The wireless system should include at least two, and preferably four, beam formers and a plurality of mobile units. The method includes the steps of transmitting beams B1, B2, B3 and B4 into first, second, third and fourth beam areas, respectively. At least two sub-areas are defined within each of the first, second, third and fourth beam areas based upon the degree of overlap with adjacent beam areas, whereby each of the beam areas includes at least one overlapping sub-area and at least one non-overlapping sub-area. The method further includes coding signals of the beams B1, B2, B3 and B4 for receipt by a particular mobile unit based upon which one of the sub-areas that the particular mobile unit is located within. If the invention is practiced with a TDM scheme, at least three time periods are utilized, wherein during the first time period (T1), simultaneous transmissions are made for receipt by mobile units located within sub-areas G11, G12, G13 and G14; during a second time period (T2), transmissions are made for receipt by mobile units located within sub-areas G21 and G24; and during a third time period (T3), transmissions are made for receipt by mobile units located within sub-areas G22 and G23. If the invention is practiced with an FDM scheme, the group of frequencies assigned to each cell is divided such that half of the frequencies serve mobile units located within sub-areas G11, G12, G13 and G14, and the other half of the frequencies serve mobile units located within sub-areas G21, G22, G23 and G24.

Abstract: In one embodiment, a service node will recognize an attempt to initiate a call from a first terminal to a second terminal, and automatically provide information to media clients associated with the first and second terminals such that a media session can be readily established between the media clients in association with the call. The service node may be configured to interact with telephony switches that support the first or second terminals, directly or indirectly via a signaling adaptor. In a second embodiment, the service node will recognize an attempt to initiate a call and will route the call to a gateway, which is controllable by the service node. Once the call is sent to the gateway, the service node may provide instructions to the gateway for routing or otherwise processing the call.

Abstract: The present invention relates to routing incoming calls to a single mobile terminal through either a wireless network or the PSTN via a terminal adapter, which is capable of wirelessly communicating with the mobile terminal. The mobile terminal may facilitate cellular calls via the wireless network, or PSTN calls via the terminal adapter. The terminal adapter monitors its ability to communicate with the mobile terminal, and provides such information to a service node, which controls whether incoming calls intended for the mobile terminal are routed through the wireless network or the PSTN. When the mobile terminal is within a communication zone of the terminal adapter, the service node routes incoming calls to the mobile terminal through the PSTN via the terminal adapter. When the mobile terminal is outside of the communication zone, the service node will route the incoming call to the mobile terminal through the wireless network.

Abstract: A telephone system supervises the redirection of an incoming telephone call to a subscriber who is not located at their expected location. Thus, when a calling party attempts to contact a subscriber who is not at their expected location, the system initially leaves the call unanswered (i.e., ringing) while initiating one or more outgoing calls to call forwarding numbers for the subscriber. If no outgoing telephone call is answered, the system directs the incoming telephone call to the subscriber's voice mail, or to another pre-determined location (e.g., an attendant). On the other hand, if the outgoing telephone call is answered, the system answers the incoming telephone call and bridges the incoming call to the answered outgoing call.

Abstract: The present invention allows communicating devices to control the amount of compression used in packet sessions for transmitting streaming media to and from each other. When a communicating device detects a decrease in performance or quality of service indicative of a limited bandwidth condition, the amount of compression for the current or subsequent sessions is temporarily increased to allow the currently available bandwidth to support the session or subsequent sessions. After a set period of time, or when the limited bandwidth condition is removed, communications associated with the sessions can revert back to transporting uncompressed data or reducing the amount of compression for the sessions, thus using more of the available bandwidth.

Abstract translation: 本发明允许通信设备控制在分组会话中使用的压缩量，用于彼此传送流媒体。 当通信设备检测到指示有限带宽条件的性能或质量降低时，临时增加当前或后续会话的压缩量，以允许当前可用带宽支持会话或随后的会话。 在一段时间之后，或者当有限带宽条件被去除时，与会话相关联的通信可以恢复到传输未压缩数据或减少会话的压缩量，从而使用更多的可用带宽。

Abstract: The present invention relates to facilitating instant messaging with an information service bureau, such as an operator or information service bureau or customer support center that has multiple information agents capable of responding to instant messages sent to a common address associated with the information service bureau. The incoming instant messages are received from users at a central location and routed to an appropriate information agent, preferably after being queued and upon an information agent becoming available. Any necessary address translation to forward the instant message to the appropriate information agent is provided at the central location. Responses to the instant message can be sent back through the central location or directly to the user; however, the instant message responses are either created or modified such that they appear to the user as coming from the central address, and not from the address of the particular servicing information agent.

Abstract: A method and apparatus for defining optical broadband services on an optical communication network enables broadband optical services to be built from basic service building blocks. According to an embodiment, a service definition software platform includes the ability to specify multiple aspects of optical broadband service to enable the optical broadband services to be defined according to optical service building blocks, gathered into service offering sets, and grouped into service groupings. Individual service offerings can then be built from the basic building blocks and from the service offering sets. By enabling the services to be broken down into building blocks that can then be used to define service sets and groups of services, service providers are more effectively able to market optical broadband services as network products. Additionally, the ability to group particular types of services together enables new types of optical broadband services to be created and offered.

Abstract: The present invention provides a service node capable of coordinating call processing for incoming calls intended for any one of multiple telephony devices of a given entity, such as a business or individual user. Switching devices, such as traditional telephony switches or internetworked gateways controlling call routing, are configured to interact with a service node to determine how to handle incoming calls to the telephony devices that they serve. As such, call processing rules, which are established by the entity, are applied to an incoming call to any of the entity's telephony devices to effectively route calls to other ones of the telephone devices, route the call to a desired voicemail system, provide call screening or blocking, and any other desired call control activity. Based on the call processing rules for the given entity, the service node will instruct the corresponding telephony switches to handle the incoming call.

Abstract: A circulating switch comprises switch modules of moderate capacities interconnected by a passive rotator. Data is sent from a one switch module to another switch module either directly, traversing the rotator once, or indirectly through at least one intermediate switch module where the rotator is traversed twice. A higher capacity extended circulating switch is constructed from higher-capacity switch modules, implemented as common memory switches and having multiple ports, interconnected through a multiplicity of rotators preferably arranged in complementary groups of rotators of opposite rotation directions. A polyphase circulating switch having a low switching delay is derived from a multi-rotator circulating switch by providing programmable rotators having adjustable relative rotator-cycle phases. A low delay high-capacity switch may also be constructed from prior-art medium-capacity rotator space switches with mutually phase-shifted rotation cycles.
