Method and system for distributed control in wireless cellular and personal communication systems

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