Abstract: PROBLEM TO BE SOLVED: To enhance the efficiency of inter-site communication between a base station controller and a mobile exchange center in a wireless system in order to reduce the cost for a communication channel and provide a reliable service to subscribers. SOLUTION: The system and the method that enhance the inter-site traffic capability as to soft hand-off can reduce a required communication capacity on a forward path between the mobile exchange center and the base station controller. The base station controller receives an original data packet for forward path transmission to a mobile station on the forward path between the mobile exchange center and the base station controller. When the mobile station performs soft hand-off, the base station controller copies the original data packet to generate a distributed data packet. The distribution data packet is sent to a corresponding base station taking part in the soft hand-off.

Abstract: PROBLEM TO BE SOLVED: To provide a system and a method for enhancing reverse traffic capacity between sites for soft hand-off in order to improve the efficiency of site-to- site communication between a base station controller and a mobile switch center. SOLUTION: The system and method for soft hand-off of this invention uses a data packet to reduce the communication capacity requested between a mobile switch center and a base station controller. The base station controller decides the best frame or data packet among duplicate frames or data packets in the reverse link from a mobile station executing the soft hand-off. Thus, the base station conducting the soft hand-off transmits not all of a plurality of data packets but only the best data packet on the reverse link between the base station controller and the mobile switch center.

Abstract: PROBLEM TO BE SOLVED: To switch an ATM connection of an ATM adaptive layer AAL-2 packet to other ATM connection in a sub ATM cell level such as logic link connection(LLC) by bundling again the ATM adaptive layer AAL-2 packet in the case that a plurality of sources and a destination are included in connection among a plurality of termination nodes. SOLUTION: An LLC server 200 bundles again two LLC packets according to two transfer tables each denoting each direction of communication and the packets are divided into two, which arrives at an adaptor TAB205 and outputs from an adaptor TAS215. Each column of the transfer tables maps a specific virtual channel connector(VCC) and a CID through a specific port to a channel IDCID in VCC, then the LLC server 200 bundles again a payload of the LLC packet arrived in the TAS205 into a new LLC packet with a new CID and gives the new LLC packet to a proper port on a designated VCC to switch the packets.

Abstract: A system and method for enhancing inter-site traffic capacity for a soft hand-off reduces the requisite communications capacity on a forward path between the mobile switching center and the base station controller. A base station controller receives an original data packet for a forward path transmission to a mobile station over the forward path between the mobile switching center and the base station controller. The base station controller copies the original data packets to generate distributional data packets if the mobile station is in a soft hand-off. The distributional data packets are sent to corresponding base stations participating in the soft hand-off.

Abstract: A digital cellular/personal communications service (PCS) application incorporate s a logical link connection (LLC) server. In this approach, there are two ATM conn ections in the path of an AAL-2 connection: one between a base station and the LLC Serve r and the other between the LLC Server and a vocoder group. All LLCs from, or to, a gi ven base station use a common ATM connection irrespective of the vocoder used at the other end. Similarly, all LLCs from, or to, a given vocoder group use a common ATM connection irrespective of the destination base station at the other end. At the LLC Server, LLC packets from many base stations destined for the same vocoder group are extracted and bundled into the ATM connection between the LLC Server and the destination vocoder group. Similar treatment is given to the packets originating at vocoders and destined for base stations. Thus, each ATM connection between a particular base station and the LLC server and each ATM connection between the L LC Server and a particular vocoder group are used to maximum capacity notwithstandi ng each ATM connection conveys LLCs to different LLC endpoints.

Abstract: A system and method for a soft-handoff uses data packets and reduces the requisite communications capacity between the mobile switching center and the base station controller. For the reverse link, the base station controller determines the best frame or data packets from a mobile station in a soft-handoff. Accordingly, only the best data packet, as opposed to data packets from all of the base stations participating in the handoff, is transmitted on the reverse link between the base station controller and mobile switching center.
