    摘要： The present invention is a user process that resides in network nodes to act as an agent for mobile terminals in, for example, PCS environments. The user process handles negotiation and complex signaling functions for the user, thus reducing the amount of signaling traffic that must travel over the valuable air interface. To achieve low call establishment times the user process is migrated as user move. Three embodiment is adapted to enable data sizes which are to be transferred to be optimized, leading to low overhead. This approach also provides flexibility when migrating across heterogeneous environments. A second alternative embodiment may be advantageously utilized when a program is compute intensive and asynchronous migration is essential. The third embodiment provides high reliability in the form of checkpointing, but incurs a high migration delay and has high memory requirement for network processors.

    摘要： A system for distributed control in wireless cellular and personal communication systems includes separate servers for performing call control and connection control functions, thereby obviating the need for a mobile switching or other switch to be anchored for the duration of a call. During a registration procedure, visiting location servers track only roaming mobiles, rather than tracking both roaming mobiles as well as mobiles located in their home network. Direct signalling links between servers and base stations, or other servers, located in different networks allow roaming mobiles to contact their home networks for service at all times, thereby obviating the need for passing signalling information for mobiles when they are not involved in a call. The use of multicast signalling with asynchronous transfer mode switches, permits specified channel control functions to take place concurrently in channel servers associated with base station and switches that form a segment of the route for a call. Similarly, specified call control functions are performed concurrently with mobile location functions, thereby decreasing the delays in setting up a call.

    摘要： A distributed, server-based communications network architecture delivers broadband and narrowband communications services. In the architecture, various traditional call processing functions, such as switching fabric or channel control, call control, and connection control are separated into distinct application processes with clearly defined interfaces for communications between these application processes. Those distinct application processes may be implemented in separate physical or logically partitioned nodes. The well-defined interfaces allow communications among: a) physical or logically partitioned nodes within a network and b) physical or logically partitioned nodes of other networks.
