Abstract

Una red celular de telecomunicaciones (20), la sincronizacion se lleva a cabo entre una unidad de sincronizacion maestra (60) ubicada en el nodo de control(30) de la red y una unidad de sincronizacion subordinada (STU) ubicada en el nodo de control oen un nodo controlado, por ejemplo, la estacion base (22), dela red. Al llevar a cabo la sincronizacion, una entre la unidad de sincronizacion maestra o la unidad de sincronizacion subordinada funciona como una unidad desincronizacion de inicio paratransmitir un mensaje con comando de análisis de la sincronizacion que incluye un parámetro (t1) a la otra entre las unidades desincronizacion que funciona como una unidad de sincronizacion de respuesta. Como respuesta a ello, la unidad de sincronizacion de respuesta envía un mensaje derespuesta del análisis de la sincronizacion que incluye al menos un segundo parámetro (t2) y, preferentemente, un tercer parámetro (t3) la unidad desincronizacion de inicio. La unidad de inicio, utiliza por ejemplo, parámetros que se toman del mensaje de respuesta del análisis de la sincronizacion paradeterminar un valor de ajuste de la sincronizacion para la unidad de sincronizacion subordinada. En los casos en los que la unidad de sincronizacion maestra esla unidad de sincronizacion de inicio, la unidad de sincronizacion maestra transmite el valor de ajuste de la sincronizacion en un mensaje con comando deactualizacion de la sincronizacion a la unidad de sincronizacion subordinada.
