    Abstract: Novel traffic management schemes of a telecommunications network using the concept of virtual links is disclosed. As an example, if a switch connects via a high bandwidth link to an access mux that drives lower bandwidth links, the mux is a potential congestion point in the downstream direction (from high to low bandwidth links) because traffic can arrive at a greater rate over the high bandwidth link than it can exit through the lower bandwidth link. If all of the traffic destined for a particular low bandwidth link can be organized into a unique virtual link, this virtual link can be scheduled at a maximum rate not exceeding the bandwidth of the low bandwidth link, thus preventing the mux from ever becoming a congestion point. Therefore, the amount of mux buffering can be reduced to a very small amount (for jitter absorption). One advantage of this scheme in this example is potentially large cost reductions in the high volume access mux at the lesser expense of a more complex low volume switch.

    Abstract: An architectural model is proposed which enables the breaking of the dedicated bond between voice-oriented peripheral equipment (PE) based resources and the voice call processing services that classically reside in PBXs, Central Offices, and Key Systems. In addition to being able to physically remote voice PE across data networks, this model enables the voice PE to become a shareable, network-owned resource (as per a Distributed Client/Server model) rather than the dedicated, non-shareable resource of a single voice host attached to the network. This places the voice PE in the same league that data resources (eg bridges, routers, ...) and server-based applications have always been. Disjoint voice products based upon this proposed architectural model would likewise be able to simultaneously share voice PE resources, thereby enabling equipment concentration and it's corresponding cost reductions at network level, as well as PE-based sparing/redundancy. In addition, a new, more powerful usage paradigm is described for the telephone that resembles that of the PC. Of course, nothing prevents the network from being configured with only a singleton voice client utilizing the various servers. This degenerate case then corresponds to a distributed, but still logically unbundled PBX complete with traditional telephones.

    Abstract: A phase-locked loop (PLL) frequency synthesizer includes a reference divider (RD) and PLL which has a phase/frequency divider (PFD), a charge pump (CP), a voltage control oscillator (VCO) and a feedback divider (FD). The RD's and FD's ratios R and N are varied. In a normal mode, the PFD and the CP cause the VCO frequency to be varied to be locked with a reference frequency. In a speed-up mode, both R and N are divided by the same factor M and the frequency of current generated by the CP is high, resulting in large average CP current and high speed lock acquisition. The R and N return to the original values (the normal mode). The frequency division ratio remains the same.

    Abstract: Methods for switching a mobile between operation in an mobile satellite system mode and a terrestrial wireless mode. When operating in the terrestrial wireless mode, the mobile terminal will initiate an attempt to switch into the MSS mode when it nears the boundary of the coverage area for a terrestrial wireless system to which it is registered. Conversely, a mobile terminal operating in the MSS mode will regularly attempt to switch into the terrestrial wireless mode. For both, a switch between modes is contingent on the mobile terminal identifying a suitable system for registration therewith upon completing the switch between modes. The criteria for identifying a suitable system for selection purposes include the following (1) the selected system is available, i.e., the mobile terminal is physically located within a coverage area for the selected system; (2) the mobile terminal is compatible with the selected system; and (3) the selected system is willing to accept the mobile terminal. If multiple systems meet these criteria, the mobile terminal will utilize a stored list of preferred systems to select therefrom. When switching into the terrestrial wireless mode, the MSS system provides the mobile terminal with switch-over information for the underlying terrestrial wireless systems and, when switching into the MSS mode, the terrestrial wireless system provides the mobile terminal with switch-over information for the overlying MSS systems.

    Abstract: A management base of a communications network manager is constructed using object oriented techniques. A network comprises a plurality of physical resources in the form of components and assemblies of components, which are distributed across the network. A management system for the network is constructed in an evolutionary manner by representing an overall functionality of the network by an application model (1402) in which each function of the network is modeled independently of its implementation, decomposing the application model into an implementation model (1404) in which every function represented in the application model is represented in the implementation model, representing the application model as a plurality of objects (1408), representing the implementation model as another plurality of objects (1411), connecting the objects of the application model and implementation model together to obtain a combined object model, and constructing a management base according to the combined object model.

    Abstract: A mobile communications system incorporates a plurality of home location registers on which subscriber data is stored such that each subscriber is allocated to a selected one of the registers for voice and/or data calls. Request messages for subscriber data can be routed to any home location register which responds to that request when the data for the respective subscriber is stored on that home location register. If the data for the respective subscriber is not stored on that home location register, the message is provided with an indicator component and is rerouted to another home location register for a further processing attempt. the number of times a message is rerouted is limited to prevent perpetual circulation of messages relating to unknown subscribers.
