Abstract

Un procedimiento de comunicación para un terminal de acceso (102), que comprende: determinar, mediante el terminal de acceso (102), un primer identificador para establecer comunicación con un primer punto de acceso (110); determinar, mediante el terminal de acceso (102), un tipo del primer identificador; determinar, mediante el terminal de acceso (102), en función del tipo del primer identificador, un segundo identificador para establecer comunicación con el primer punto de acceso (110) si se detecta confusión con respecto al primer identificador, donde el terminal de acceso (102) determina de manera autónoma cúando adquirir el segundo identificador sin instrucciones mediante un nodo externo, donde la determinación del segundo identificador está basada además en si un valor del primer identificador es uno de un conjunto de valores designados que están asociados a puntos de acceso que no están libres de confusión, un grupo cerrado de abonados y puntos de acceso de al menos un tipo designado; donde el primer y el segundo identificador se usan para identificar el primer punto de acceso; y donde el terminal de acceso (102) envía el segundo identificador a un segundo punto de acceso (104) que está dando servicio actualmente al terminal de acceso (102).

y transmitir el identificador seleccionado a un segundo punto de acceso cuando se establece comunicación con el segundo punto de acceso. Además, en algunos aspectos, al menos uno de lo siguiente también puede aplicarse al cuarto procedimiento de comunicación: la selección del identificador se basa en un tipo de nodo asociado al primer punto de acceso; el conjunto de identificadores comprende un primer identificador y un segundo identificador, y el identificador seleccionado comprende el segundo identificador; el primer identificador comprende un identificador de célula física asociado al primer punto de acceso, un desfase de número pseudoaleatorio asociado al primer punto de acceso o una señal piloto de adquisición asociada al primer punto de acceso, y el segundo identificador comprende un identificador de célula global asociado al primer punto de acceso, una dirección de Protocolo de Internet asociada al primer punto de acceso, o un identificador que identifica de forma exclusiva al primer punto de acceso dentro de una red; el segundo identificador se selecciona para evitar la confusión que de lo contrario puede ser causada por la utilización del primer identificador a la hora de establecer comunicación con el segundo punto de acceso; la selección del identificador se basa en si un valor del primer identificador es uno de un conjunto de valores designados; el conjunto de valores designados está asociado a al menos uno del grupo que consiste en: puntos de acceso que no están libres de confusión, un grupo cerrado de abonados y puntos de acceso de al menos un tipo designado; el al menos un tipo designado se refiere a al menos uno del grupo que consiste en: potencia de transmisión, área de cobertura y capacidades de retransmisión; el procedimiento comprende además recibir una lista del conjunto de valores designados desde el primer punto de acceso; el identificador seleccionado se transmite junto con una solicitud de conexión; la selección del identificador se inicia por una pérdida de comunicación con el primer punto de acceso; el identificador seleccionado es utilizado por el segundo punto de acceso para establecer comunicación con el primer punto de acceso y/o para obtener información de configuración a partir del primer punto de acceso; el primer punto de acceso comprende una femtocélula o una picocélula; el primer punto de acceso da servicio a un conjunto restringido de al menos un terminal de acceso.
En algunos aspectos, un aparato de comunicación comprende: un controlador de comunicación configurado para comunicarse con un primer punto de acceso; y un controlador de identificador configurado para seleccionar un identificador de un conjunto de identificadores asociado al primer punto de acceso; donde el controlador de comunicación está configurado además para transmitir el identificador seleccionado a un segundo punto de acceso cuando se establece comunicación con el segundo punto de acceso.
En algunos aspectos, un aparato de comunicación comprende: medios para establecer comunicación con un primer punto de acceso; medios para seleccionar un identificador de un conjunto de identificadores asociados al primer punto de acceso; y medios para transmitir el identificador seleccionado a un segundo punto de acceso cuando se establece comunicación con el segundo punto de acceso.
En algunos aspectos, un producto de programa informático comprende: un medio legible por ordenador que comprende códigos para hacer que un ordenador: se comunique con un primer punto de acceso; seleccione un identificador de un conjunto de identificadores asociados al primer punto de acceso; y transmita el identificador seleccionado a un segundo punto de acceso cuando se establece comunicación con el segundo punto de acceso.
En algunos aspectos, un quinto procedimiento de comunicación comprende: determinar si una pluralidad de células utilizan un identificador de célula idéntico de un primer tipo; y enviar una solicitud de un identificador de célula de un segundo tipo asociado al identificador de célula del primer tipo según la determinación. Además, en algunos aspectos, al menos uno de lo siguiente puede aplicarse también al quinto procedimiento de comunicación: el identificador de célula del primer tipo comprende un identificador de célula física, y el identificador de célula del segundo tipo comprende un identificador de célula global; el procedimiento comprende, además, recibir un informe de mediciones que indica que una de las células utiliza un identificador de célula que podría causar confusión; la determinación se basa en el descubrimiento de nodos vecinos que indica identificadores de célula utilizados por las células; la determinación se basa en un mensaje recibido que indica qué identificadores de célula son utilizados por las células; el procedimiento comprende además: recibir una respuesta a la solicitud, donde la respuesta comprende el identificador de célula del segundo tipo, e iniciar un traspaso utilizando el identificador de célula del segundo tipo; las células comprenden femtocélulas o picocélulas; el procedimiento se lleva a cabo mediante una estación base.
En algunos aspectos, un aparato de comunicación comprende: un detector de confusiones configurado para determinar si una primera célula y una segunda célula utilizan un identificador de célula idéntico de un primer tipo; y un controlador de identificador configurado para enviar una solicitud de un identificador de célula de un segundo tipo asociado al identificador de célula del primer tipo según la determinación.
En algunos aspectos, un aparato de comunicación comprende: medios para determinar si una primera célula y una segunda célula utilizan un identificador de célula idéntico de un primer tipo; y medios para enviar una solicitud de un identificador de célula de un segundo tipo asociado al identificador de célula del primer tipo según la determinación.
En algunos aspectos, un producto de programa informático comprende: un medio legible por ordenador que comprende códigos para hacer que un ordenador: determine si una primera célula y una segunda célula utilizan un identificador de célula idéntico de un primer tipo; y envíe una solicitud de un identificador de célula de un segundo tipo asociado al identificador de célula del primer tipo según la determinación.
