CA 2395983

Methods and apparatuses are provided for CDMA (code division multiple access) access availability to a large cell area, and for traffic channel establishment. A group of cell site modems are configured to lock for access attempts generated in respective complete and/or sectorized circular or annular shaped areas centred at the centre of the cell area, the areas collectively covering the cell area. To achieve this, each cell site modem has a local clock and the local clock within the first of the cell site modems is synchronized with a standard network time, and the local clock of each of the subsequent cell site modems is offset by a respective delay with respect to the standard network time causes the cell site modem to search within its respective annular shaped area. A cell site modem is also made available as a traffic cell site modem and is operable to have its traffic acquisition search window centred at a location of an access attempt.

L'invention concerne des procédés et des dispositifs permettant un accès AMRC (accès multiple par répartition de code) à une zone cellulaire de grande dimension, et la mise en oeuvre de canaux de trafic. Un ensemble de modems rattachés au site cellulaire comprend des modems conçus pour détecter les tentatives d'accès générées dans les zones circulaires ou annulaires respectives, complètes et/ou sectorisées, centrées sur le centre de la zone cellulaire, et couvrant ensemble la superficie de la cellule. A cette fin, chaque modem de site cellulaire comprend une horloge locale. L'horloge locale du premier modem de site cellulaire est synchronisée avec un temps normal de réseau, et l'horloge locale de chaque modem de site cellulaire suivant est décalée avec un retard respectif par rapport au temps normal de réseau, de sorte que les explorations de chaque modem de site cellulaire sont localisées à l'intérieur d'une zone annulaire respective. Un modem de site cellulaire est également exploité en tant que modem de trafic, et fonctionne par centrage de sa fenêtre de recherche pour acquisition de trafic sur l'emplacement d'une tentative d'accès.
