Abstract: A Code Division Multiple Access cellular communication system comprises a base station (101) supporting a remote station (117) making uplink transmissions using an uplink scrambling code in a first cell. A controller (119) determines a first set of uplink scrambling codes from an identity of the first remote station (117) and selects the used code therefrom. The first set has a unique dependency upon the identity. An access point (111) comprises a group processor (203) which determines the group of remote stations registered at the access point (including the first remote station (117)). A measurement code processor (205) determines the uplink scrambling codes potentially used by the registered remote stations. A measurement unit (207, 209) then monitors for received signals using these codes and a handover detection processor (211) generates a potential handover detection for the first remote station (117) in response to a detection of a received signal using the uplink scrambling code of the first remote station (117).

Abstract: A cellular communication system comprises a media gateway (111) which interfaces with a packet switched network (113) and a circuit switched network (115). First and second Radio Network Controllers (RNCs) (105,109) are coupled to the media gateway via the packet switched data network (115) and support a real time communication from a remote station (101). The media gateway time aligns the received packet data in response to timestamps of these. Each of the first and second RNC comprise a Node B interface (201) which receives real time data being data of an air interface communication from the remote station (101) to a base station (103,107) supported by the RNC. A packet processor (203,205) then transmits the data packets to the media gateway via the packet switched network (113). A timestamp processor (207) determines timestamps for the data packets in response to a timing characteristic of the air interface communication.

Abstract: A network element (115) for a cellular communication system supports base stations (111,113) with a shared pilot signal scrambling code. The network element (115) receives a relocation request message for a remote station (117) supported by a base station (101). The relocation request comprises an identification of the shared scrambling code. A group processor (205) determines a group of potential target base stations (111, 113) for the relocation request in response to the identification of the shared pilot signal scrambling code. A request processor (207) transmits a request message to the target base stations (111, 113). The request message comprises a parameter indication for an uplink transmission from the remote station (117) to the base station (101) and requests the target base stations (111, 113) to measure the uplink transmission. A measurement processor (209) receives measurement reports for the uplink transmission from the target base stations and a selection processor (211) selects a handover target base station (111) from the target base stations (111, 113) based on the measurement reports.

Abstract: A cellular communication system is supported by first physical layer processes, second layer user plane control processes and third layer control plane control processes. The first layer process is executed in a base station (101). A distribution controller (113) allocates the layer processes such that the second layer process is executed in a different network element than the third layer process. The second and/or third layer process may furthermore be allocated to a different network element than the base station (101) executing the first layer process. The second and/or third layer process may be allocated to base stations (103, 105). This allows improved load balancing and/or may reduce RNC relocations in a system having base station RNC functionality.

Abstract: A cellular communication system supports a communication of a user equipment (111). The communication is supported by a first layer process comprising physical layer processes, a second layer process comprising user plane control processes and a third layer process comprising control plane control processes. The first layer process is executed in a base station (101) which communicates with the user equipment (111) over the air interface. A distribution controller (113) allocates the layer processes such that the second layer process is executed in a different network element than the third layer process. The second and/or third layer process may furthermore be allocated to a different network element than the base station (101) executing the first layer process. The second and/or third layer process may be allocated to base stations (103, 105). The invention may allow improved load balancing and/or may reduce RNC relocations in a system having RNC functionality located in the base stations.
