Abstract: Several mobile assisted handoff methods for use in the cellular communication system comprising a plurality of cells are disclosed. First, the quality level of a cell a mobile station is presently using is measured to determine whether the quality level is above or below a threshold. If the quality level is below the threshold, a primary list of cells is assigned to the mobile station, whereas if the quality level is above the threshold, a secondary list of cells is assigned to the mobile station. The quality level of each of the assigned cells is then measured by the mobile station and reported to the communication system.
Abstract translation: 公开了在包括多个小区的蜂窝通信系统中使用的几种移动辅助切换方法。 首先，测量移动台正在使用的小区的质量水平，以确定质量水平是否高于或低于阈值。 如果质量水平低于阈值，则将小区的主要列表分配给移动站，而如果质量水平高于阈值，则将小区的次要列表分配给移动站。 然后由移动台测量每个分配的小区的质量等级并向通信系统报告。

Abstract: A cellular mobile radiotelephone system listens for call accesses on a control channel of an umbrella cell and on a control channel of a microcell located within said umbrella cell and responds to the call access only on the control channel of the umbrella cell. More particularly, the microcells within a particular umbrella cell are provided with listen-only control channel at the same frequency as the uplink control channel of the umbrella cell. An umbrella cell and one or several of its microcells may therefore each receive the same call accesses. During call access, the umbrella cell and each of the microcells determines the strength of the received signal and forwards this information to the system. The system selects the most appropriate cell out of the umbrella cell and the microcells to handle the call and causes the umbrella cell to respond to the call access on its downlink control channel. Among the umbrella cell and its microcells, there are therefore a plurality of uplink control channels, one for each defined cell, and a single downlink control channel, namely that of the umbrella cell. Cell planning remains unchanged as does a directed retry mechanism. Because there is only a single downlink control channel within the coverage area of an umbrella cell, excessive rescanning is avoided. Furthermore, a call is established at the outset in the most appropriate cell, using resources more efficiently and avoiding congestion in the umbrella cell.

Abstract: CANAL DE CONTROL DE ESCUCHA EN UN SISTEMA CELULAR DE RADIOTELEFONO MOVIL. ESTE SISTEMA ESCUCHA ACCESOS DE LLAMADA EN CANALES DE CONTROL DE UNA CELULA PARAGUAS Y DE UNA MICROCELULA SITUADA DENTRO DE ELLA Y RESPONDE AL ACCESO DE LLAMADA SOLAMENTE EN EL CANAL DE CONTROL DE LA CELULA PARAGUAS. UNA CELULA PARAGUAS Y UNA O VARIAS DE SUS MICROCELULAS PUEDEN RECIBIR LOS MISMOS ACCESOS DE LLAMADA. DURANTE LOS ACCESOS DE LLAMADA, LA CELULA PARAGUAS Y CADA UNA DE LAS MICROCELULAS DETERMINAN LA INTENSIDAD DE LA SEÑAL RECIBIDA Y REMITEN ESTA INFORMACION AL SISTEMA. ESTE SELECCIONA UNA CELULA ADECUADA PARA MANEJAR LA LLAMADA Y HACE QUE LA CELULA PARAGUAS RESPONDE AL ACCESO DE LLAMADA EN SU CANAL DE CONTROL DE ENLACE DESCENDENTE. EL INVENTO PERMITE QUE SE ESTABLEZCA UNA LLAMADA EN LA CELULA MAS APROPIADA Y EVITA QUE SE CONGESTIONE LA CELULA PARAGUAS.
