Abstract: A system network and method improving handovers, particularly for reducing the amount of inter-cellular transfer information stored in base station controllers or radio network controllers, is disclosed. Instead of storing routing information for every possible inter-cellular handover at each control node, signaling network technology is employed to effectuate communication of all relevant inter-cellular handover information between all of the control nodes, thereby coordinating routing information transference across a distributed system.

Abstract: A data mechanism is described for assisting third generational mobile radio systems to handoff mobile radio connection to neighboring cells when the neighboring cells are of a foreign generational type. The data mechanism includes a container in the data map which is a generic structure, not particular to any generational system. The generic structure can be content-specific to any of many different generational communications protocols.

Abstract: A system for inhibiting the transmission of an access request message from a mobile station when either the system is incapable of granting access at the class of service desired by the mobile or access by the mobile at that class of service would increase the interference level of the target base station or a neighboring base station past its interference capacity. In one embodiment, each base station broadcasts a maximum data rate access parameter and any mobile receiving that parameter and seeking access at a greater data rate refrains from transmitting an access request message. In another embodiment, each mobile calculates from its path loss to the base station the power level it must transmit in order to gain access as well as the effect of that transmission on the interference level of both the target base station and neighboring base stations. If transmission at the required power level would increase the interference level of any base station past its maximum capacity, the transmission is inhibited. The system is most effective in CDMA mobile cellular radio systems.

Abstract: A telecommunications system employing WCDMA technology in a preferred embodiment, utilizes compressed mode techniques to allow a mobile station to take measurements on another frequency in preparation for inter-frequency transfer. The current assumption is that the compressed mode characteristics are controlled by the network, but such control leads to problems when one considers that the slot characteristics are very dependent upon the mobile station characteristics. In the present invention, the control of the slot specifications are dictated by the mobile station to the network and acknowledged by the network to the mobile station. Thereafter, the network informs the WCDMA base station of the slot specifications, which are then imposed from the CDMA base station to the mobile station. Once the mobile station receives the slot from the WCDMA base station, the mobile station is confident that the slot will conform with the characteristics that the mobile station needs in order to make the appropriate measurements.

Abstract: A radio access network portion of a telecommunications network (18) which serves a mobile station (MS) is connecting to a core network. The radio access network portion has plural base stations (BS) serving respective plural cells (C), as well as plural control nodes (RNCs). The control nodes include a first control node (RNC1) for controlling a first group of the plural base stations and a second control node (RNC2) for controlling a second group of the plural base stations. A multicell area (MCA) includes cells served by at least some of the first group of base stations and cells served by at least some of the second group of base stations. The radio access network portion of a telecommunications network further has a paging control node which stores information regarding the multicell area. To page the mobile station in the multicell area, the paging control node (1) sends paging messages to each of the base stations serving the multicell area controlled by the paging control node: and (2) sends a paging message to any other control nodes which control base stations serving cells in the multicell area. The paging control node determines to which base stations and other control node(s) it should send paging messages by consulting a paging table (100). Preferably the paging control node is one of the control nodes of the radio access network. The paging control node is connected to the other control node(s) by an inter-control node link (32) over which the paging message is sent.

Abstract: In connection with a diversity handling moveover procedure for a cellular system having soft handover, allocation of a replacement diversity handling unit in a target node occurs only after a moveover decision has been made by a source node. Initially, an original or source diversity handling unit at the source node performs connection combining and connection splitting functions for legs of a mobile connection routed through plural base stations serving a mobile station. In accordance with movement of the mobile station, the source node makes the movement decision. The moveover decision can be based on factors such as base station utilization and/or actual and/or predicted directional movement of the mobile station. In some embodiments, the diversity handling moveover procedure involves selection among plural nodes for situs of the replacement or target diversity handling unit.

Abstract: A DS-CDMA cellular system is provided that employs two forward link transmission modes in parallel. A conventional transmission mode broadcasts a pilot channel that can be used by a conventional mobile station to estimate and detect a dedicated traffic channel. The second transmission mode transmits (via a sectorized or narrow lobe antenna system) all information required by a new generation mobile station to estimate and detect a traffic channel dedicated to that mobile station. Consequently, DS-CDMA system operators can introduce the use of adaptive array antenna systems or distributed antenna systems with new generation mobile stations, without terminating the use of the conventional mobile stations.
