Abstract: A cellular communication system and method for determining cell relations between cells is disclosed. The cellular communication system transmits signals from one or more transmitters, for example, mobile stations or base stations, over a plurality of radio frequency channels that are assigned to the cells. The transmitted signals over the plurality of radio frequency channels are received at each one of the cells and their received signals strengths are measured at corresponding measurement times. The received sign al strength measurements and corresponding measurement times are processed to determine whether a measured received signal strength at a corresponding measurement time is based on a transmission from a single transmitter in a cell. The measurements corresponding to signals found originated from single transmitters are used for determining the cell relations in terms of such parameters as path gain values or C/I ratios.

Abstract: A system and method of ensuring that a called mobile station's expected service type matches a calling party's service type in a radio telecommunications network in which both voice service and data service are provided. A service code generator (51) in a serving mobile switching center (MSC)(22) generates a service code that indicates the calling party's service type. The service code is sent in a page (29) from the serving MSC to the mobile station (24), and includes the service code. An expected service code generator in the called mobile station generates an expected service code that indicates the called mobiles station's expected service type. The expected service code is sent in a page response (32) from the mobile station to a border MSC (26) that borders the serving MSC. The border MSC (26) extracts the expected service code and sends it to the serving MSC (22) where it is compared with the calling party's service code. If the service codes match, the call is connected to be mobile station. If the service codes do not match, the mobile station is denied access to the radio telecommunications network.

Abstract: A cellular communications network includes a plurality of cells (100) whos e base stations have both sector (104) and smart (110) antenna capabilities. While engaged in a call (200), mobile station (114) downlink signal strength measurements (202,204) are made on its own serving traffic channel and the control channe ls of neighboring cells. These measurements are then adjusted (210) by one or more factors which take into account the operational and physical differences between sector antenna and smart antenna. For example, the signal strength measurements may be appropriately adjusted by measured differences in gain between the smart antenna and sector antennna, output power backoff values associated with smart antenna a nd sector antenna support of the traffic channels in comparison to the control channel s, and power control attenuation applied to the traffic channels. The resulting adjusted downlink signal strength measurements may then be compared against each othe r (as off-set by any imposed hysteresis value) to more precisely locate the mobile station and uniformly, predictably and accurately identify when it is appropriate to authorize a hand-off
