Abstract
Procedimiento para operar una red de gestión de una red de telecomunicaciones con un agente (NE), así como un primer gestor (NMC) y un segundo gestor (EM), realizándose una comunicación entre el agente (NE) y el primer gestor (NMC) a través una primera interfaz y entre el agente (NE) y el segundo gestor (EM) a través de una segunda interfaz, utilizándose para la comunicación a través de la primera interfaz un primer modelo de objetos (MODEL1) y para la comunicación a través de la segunda interfaz un segundo modelo de objetos (MODEL2) para la modelización de recursos de la red de telecomunicaciones, caracterizado porque en una comunicación entre el agente (NE) y el segundo gestor (EM), el segundo gestor (EM) recibe mensajes del agente (NE) utilizando el segundo modelo de objetos (MODEL2) y los retransmite al primer gestor (NMC) utilizando el primer modelo de objetos (MODEL1).
Description
Procedimiento y equipos para cambiar el modo de
funcionamiento de un agente de una red de gestión.
La invención se refiere a un procedimiento para
operar una red de gestión, con un agente, así como con un primer y
un segundo gestor, teniendo lugar entre el agente y el primer gestor
una comunicación a través de una primera interfaz y entre el agente
y el segundo gestor una comunicación a través de una segunda
interfaz. Además, se refiere la invención a un agente y un gestor
para ejecutar el procedimiento.
Según los principios de una red de gestión,
denominados también principios TMN (TMN: Telecommunications
Management Network, red de gestión de telecomunicaciones), existen
varias capas de gestión para la gestión de un sistema de
comunicaciones - como por ejemplo un sistema de comunicaciones de
telefonía móvil - teniendo cada capa, a excepción de la capa más
superior y la más inferior, una función doble, a saber, una función
de gestor y una función de agente. En el sistema de gestión
("managing system") ejerce cada capa, a excepción de la capa
más inferior, una función de gestor para la capa que se encuentra
debajo de ella. En el sistema gestionado ("managed system")
tiene cada capa, a excepción de la más superior, una función de
agente para la siguiente capa que se encuentra encima.
Los gestores arrancan operaciones para la
vigilancia y control de la red, enviando los llamados
"requests" (solicitudes), que son ejecutados por agentes, y
reciben los correspondientes avisos de retorno, los llamados
"responses" (respuestas) de los agentes. Los equipos o bien
elementos de la red de telecomunicaciones, también denominados
recursos de la red de telecomunicaciones, que en una jerarquía TMN
ejercen el papel de un agente, detectan sucesos relevantes, los
llamados "events", como por ejemplo alarmas, generan los
correspondientes avisos, los llamados "notifications", y los
transmiten en forma de avisos de sucesos, los llamados "event
reports" a los gestores, para posibilitar una gestión eficiente
de la red.
La gestión de la red puede incluir entre otros
la gestión de errores (Fault Management) y/o la gestión de la
configuración (Configuration Management) y/o la gestión de la
seguridad (Security Management) y/o la gestión de la facturación
(Accounting Management) y/o la gestión de las prestaciones
(Performance Management). Mediante la gestión de la red deben
ponerse a disposición mecanismos adecuados para la distribución y
gestión de la información, con lo que en caso necesario se dispone
de una imagen completa sobre el estado de la red y pueden vigilarse
y configurarse los distintos recursos de la red de
telecomunicaciones de manera eficiente.
La comunicación gestor-agente se
realiza a través de las llamadas interfaces de gestión o bien
interfaces gestor-agente, que se caracterizan en un
entorno orientado a objetos por un protocolo de comunicaciones, como
por ejemplo: CMIP (Common Management Information Protocol,
protocolo común de gestión de la información) según
ITU-T X.777 o CORBA (Common Object Request Broker
Architecture, arquitectura común de intermediarios en peticiones a
objetos) y mediante un modelo de objetos. Los modelos de objetos
sirven para la modelización de recursos de la red de
telecomunicaciones.
Tales interfaces existen por ejemplo entre por
un lado el nivel de gestión de elementos de red (Network Element
Management Level) y por otro lado el nivel de elementos de red
(Network Element Level). Un ejemplo de equipos de red de esta
interfaz gestor-agente, son los centros de operación
y mantenimiento (OMC: Operation and Maintenance Center) por el lado
del nivel de gestión de elementos de red, así como por el lado del
nivel de elementos de red, equipos como por ejemplo estaciones de
base del sistema de estaciones de base (BSS: Base Station System)
de una red de telefonía móvil GSM, o estaciones de base de otras
redes de comunicaciones, por ejemplo NodeBs de una red de telefonía
móvil UMTS (UMTS: Universal Mobile Telecommunication System) o
puntos de acceso a radio de un sistema WLAN (WLAN: Wireless Local
Area Network, red de área local inalámbrica), por ejemplo según uno
de los estándares IEEE 812. 11.
Las interfaces de gestión o bien interfaces
gestor-agente existen también entre por un lado el
nivel de gestión de la red (Network Management Level) y por otro
lado el nivel de gestión de elementos de la red. Un ejemplo de
equipos de red para esta interfaz gestor-agente son
los centros de gestión de la red (NMC: Network Management Center)
por el lado del nivel de gestión de la red y los centros de
operación y mantenimiento (OMC: Operation and Maintenance Center)
por el lado del nivel de gestión de la red, por ejemplo en el citado
GSM o en otra red de telefonía móvil o de telecomunicaciones.

describe un agente que apoya tanto
CMIP como también SNMP. El agente puede comunicar con aplicaciones
SNMP y CMIP. El mismo dispone de una MIB (Management Information
Base, base de información de gestión), que es independiente del
protocolo. A esta MIB pueden acceder tanto el procesador del
protocolo CMIP como también el del SNMP del
agente.

describe un proxy (intermediario
que almacena informaciones de consulta frecuente) que se encuentra

utilizando el GMIP, realiza una conversión entre mensajes CMIP y
mensajes SNMP y comunica con el agente utilizando
SNMP.
La invención tiene como tarea básica mostrar un
procedimiento eficiente para operar una red de gestión en donde
existan varias interfaces entre un agente y gestores. Además, deben
presentarse un gestor adecuado y un agente que también lo sea para
realizar el procedimiento.
Esta tarea se resuelve mediante un procedimiento
con las particularidades de la reivindicación 1, así como mediante
un gestor y un agente con las particularidades de las
reivindicaciones subordinadas.
Ventajosas mejoras y perfeccionamientos son
objeto de las reivindicaciones secundarias.
En el procedimiento correspondiente a la
invención para operar una red de gestión de una red de
telecomunicaciones con un agente, así como con un primer y un
segundo gestor, se realiza una comunicación entre el agente y el
primer gestor a través de una primera interfaz y entre el agente y
el segundo gestor a través de una segunda interfaz. En el marco de
la invención se utiliza para la comunicación a través de la primera
interfaz un primer modelo de objetos y para la comunicación a
través de la segunda interfaz un segundo modelo de objetos para la
modelización de recursos de la red de telecomunicaciones.
A través de interfaces, se comunica el agente
con gestores, caracterizándose la correspondiente interfaz, entre
otros, por un modelo de objetos. Con ayuda de un modelo de objetos
se modelizan recursos de red de la red de telecomunicaciones. Los
recursos se distribuyen según el modelo de objetos en clases de
objetos, pudiendo presentar cada clase de objetos diversos
atributos. Las clases de objetos pueden repartirse por ejemplo en
clases de objetos lógicas o bien funcionales y referidas a hardware,
la mayoría de las veces dependientes del fabricante. El agente está
según la invención en condiciones de comunicar con gestores
utilizando diversos modelos de objetos. Estas comunicaciones pueden
realizarse tanto simultáneamente como también sucesivamente. El
agente puede ser por ejemplo un elemento de red, el primer gestor un
centro de gestión de la red y el segundo gestor un gestor de
elementos de red de un sistema de comunicaciones de telefonía móvil.
Además del agente y del primer y segundo gestor, pueden ser objeto
de la gestión de red otros equipos. El procedimiento correspondiente
a la invención puede aplicarse sobre un conjunto de distintas
interfaces entre un agente y gestores.
Según un perfeccionamiento ventajoso de la
invención, se realiza una conmutación de una primera comunicación
entre el agente y el primer gestor utilizando el primer modelo de
objetos y una comunicación entre el agente y el segundo gestor
utilizando el segundo modelo de objetos y/o a la inversa. Esto
significa que el agente no puede comunicar simultánea, sino
sucesivamente, con el primer y el segundo gestor. La conmutación se
realiza ventajosamente durante el servicio del agente, es decir,
que en particular el agente no tiene que ser desconectado durante
la conmutación. Durante una desconexión no podría desempeñar el
agente su función como agente.
En un perfeccionamiento de la invención envía el
gestor que actualmente comunica con el agente al agente una
solicitud de cambio de la comunicación al otro agente, a
continuación de lo cual se realiza la conmutación. En particular
esta solicitud puede constar de una solicitud de desacoplar el
enlace existente con el gestor y de establecer un nuevo enlace con
el otro gestor. De manera ventajosa contiene la solicitud
informaciones de identificación del gestor al que debe realizarse
la conmutación.
Es ventajoso que el agente conmute a solicitud
del gestor con el que él comunica y con ello se realice la
conmutación. La solicitud la recibe el agente preferentemente de
aquel gestor con el que él comunica actualmente. El agente puede
provocar la conmutación finalizando el enlace con el gestor con el
que él comunica en ese momento y estableciendo un enlace
automáticamente con el correspondiente otro gestor, es decir, sin
que tenga lugar una solicitud por parte del nuevo gestor.
Según un perfeccionamiento de la invención, el
segundo gestor recibe del agente mensajes en una comunicación entre
el agente y el segundo gestor, utilizando el segundo modelo de
objetos, y retransmite los mismos utilizando el primer modelo de
objetos al primer gestor. En este caso pertenecen el primer y el
segundo gestor a distintos niveles de gestión y se encuentran entre
sí en una relación gestor-agente.
Es ventajoso que el agente convierta los
mensajes que recibe o genera del primer modelo de objetos en
mensajes del segundo modelo de objetos y/o a la inversa. Esto es
especialmente favorable cuando el agente puede generar todos los
mensajes para el primer y el segundo gestor exclusivamente
utilizando uno de los modelos de objetos y/o puede procesar todos
los mensajes del primer y del segundo gestor exclusivamente
utilizando uno de los modelos de objetos.
El gestor correspondiente a la invención para
una red de gestión que incluye al menos otro gestor y un agente de
una red de telecomunicaciones, dispone de elementos para la
comunicación con el agente utilizando un primer modelo de objetos
para modelizar recursos de la red de telecomunicaciones. Además, el
mismo presenta elementos para enviar una solicitud al agente
finalizar una comunicación utilizando el primer modelo de objetos
entre el gestor y el agente y para iniciar una comunicación
utilizando un segundo modelo de objetos entre el otro gestor y el
agente.
El agente correspondiente a la invención para
una red de gestión que incluye al menos un primer gestor y un
segundo gestor de una red de telecomunicaciones, dispone de
elementos para la comunicación con el primer gestor utilizando un
primer modelo de objetos para modelizar recursos de la gestión de
red. En el marco de la invención presenta el agente además
elementos para la comunicación con el segundo gestor utilizando un
segundo modelo de objetos, para modelizar recursos de la red de
telecomunicaciones.
En un perfeccionamiento de la invención,
presenta el agente además elementos para cambiar el gestor, con los
que él comunica en ese momento, del primer gestor al segundo gestor
y/o a la inversa y para el correspondiente cambio del modelo de
objetos utilizado para la comunicación.
Es ventajoso que el agente presente además
elementos para transformar los mensajes recibidos o generados por
él del primer modelo de objetos en mensajes del segundo modelo de
objetos y/o la inversa.
Ventajosamente presenta el agente además
elementos para recibir una solicitud del primer gestor para
finalizar una comunicación utilizando el primer modelo de objetos
entre el primer gestor y el agente y para iniciar una comunicación
utilizando el segundo modelo de objetos entre el segundo gestor y el
agente y/o una solicitud del segundo gestor de finalizar una
comunicación utilizando el segundo modelo de objetos entre el
segundo gestor y el agente y para el comienzo de una comunicación
utilizando el primer modelo de objetos entre el primer gestor y el
agente.
Tanto el gestor correspondiente a la invención
como también el agente correspondiente a la invención son
especialmente adecuados para realizar el procedimiento
correspondiente a la invención, siendo esto también así con
referencia a la mejora y perfeccionamiento. Para ello pueden
presentar los mismos otros elementos adecuados.
A continuación se describirá la invención más en
detalle en base a un ejemplo de ejecución. Al respecto muestran:
Figura 1a: una primera configuración de una red
de gestión,
figura 1b: una segunda configuración de una red
de gestión.
Se considera en las figuras 1a y 1b una red de
gestión de una red de telecomunicaciones, que presenta tres niveles
de jerarquía E1, E2 y E3. El nivel más alto E1 pertenece al centro
de gestión de red NMC, que funciona como gestor respecto a los
equipos de la gestión de red de los niveles de jerarquía más
inferiores E2 y E3. El nivel de jerarquía intermedio E2 pertenece a
un gestor de elementos de red EM, que puede ser por ejemplo un OMC
de un sistema de comunicaciones de telefonía móvil. El nivel de
jerarquía más inferior E3 pertenece a un elemento de red NE, que
puede ser por ejemplo una estación de base de un sistema de
comunicaciones de telefonía móvil.
Según la figura 1a es posible que el elemento de
red NE comunique con el gestor de elementos de red EM, mientras que
el gestor de elementos de red EM comunica con el centro de gestión
de red NMC. De esta manera pueden por ejemplo retransmitirse avisos
de error del elemento de red NE desde el gestor de elementos de red
EM al centro de gestión de red NMC. El gestor de elementos de red
EM funciona así respecto al elemento de red NE como gestor,
simbolizado mediante una primera parte EM-MANAGER
del gestor del elemento de red EM y respecto al centro de gestión
de red NMC como agente, simbolizado por una segunda parte
EM-AGENT del gestor de elementos de red EM. Según
la figura 1b es también posible no obstante que el elemento de red
NE comunique directamente con el centro de gestión de red NMC y
envíe a éste por ejemplo avisos de error. El elemento de red NE
puede así ser gestionado tanto por el centro de gestión de red NMC
como también por el gestor de elementos de red EM.
Las interfaces entre el centro de gestión de red
NMC y el gestor de elementos de red EM, así como entre el centro de
gestión de red NMC y el elemento de red NE y entre el gestor de
elementos de red EM y el elemento de red NE se caracterizan por la
utilización de respectivos modelos de objetos. Los modelos de
objetos se utilizan en la red de gestión para describir recursos de
la red de telecomunicaciones. El centro de gestión de red NMC
utiliza para la comunicación tanto con el gestor de elementos de red
EM como también con el elemento de red NE un primer modelo de
objetos MODEL1. Así existe desde el punto de vista del centro de
gestión de red NMC una interfaz de gestión unificada,
independientemente de qué equipo se encuentra en el otro extremo de
la interfaz. Entre el gestor del elemento de red EM y el elemento de
red NE tiene lugar la comunicación utilizando un segundo modelo de
objetos MODEL2, que se diferencia del primer modelo de objetos
MODEL1. El elemento de red NE presenta tanto elementos MEANS MODEL2
que le permiten comunicar utilizando el segundo modelo de objetos
MODEL2, como también elementos MEANS MODEL1, que le permiten
comunicar utilizando el primer modelo de objetos MODEL1.
En el marco de la invención apoya el elemento de
red NE dos modos de funcionamiento diferentes. La figura 1a
corresponde al funcionamiento del elemento de red NE en el modo EM,
en el que el elemento de red NE es gestionado o bien controlado por
el gestor de elementos de red EM, mientras que la figura 1b
representa el caso de que el elemento de red NE es gestionado o
bien controlado en el modo NM directamente por el centro de gestión
de red NMC. Cada modo de funcionamiento está ligado así, desde el
punto de vista del elemento de red NE, directamente a un modelo de
objetos MODEL1 o MODEL2. Se parte en lo que sigue de que en cada
momento sólo está activo un modo de funcionamiento del elemento de
red NE, con lo que se conecta entre los modos de funcionamiento de
uno a otro y viceversa. Pueden no obstante realizarse también
elementos de red NE que utilicen a la vez ambos modos de
funcionamiento descritos.
En la instalación inicial del elemento de red NE
es razonable arrancar éste por defecto en el modo EM, hasta que la
primera configuración se ha completado con ayuda del gestor de
elementos de red EM específico del fabricante. El elemento de red
NE comunica así al comienzo utilizando el segundo modelo de objetos
MODEL2. Según este modelo de objetos MODEL2, se envían alarmas al
gestor de elementos de red EM, mediante el cual se realiza una
conversión de los avisos de sucesos del elemento de red NE al primer
modelo de objetos MODEL1 (el llamado mapping o mapeado), a
continuación de lo cual se retransmite el aviso de sucesos
utilizando el primer modelo de objetos MODEL1 al centro de gestión
de red NMC.
Tras esta fase de inicialización puede ser
vigilado el elemento de red NE en el modo de funcionamiento NM por
el centro de gestión de red NMC. Para la conmutación al modo de
funcionamiento NM envía primeramente el gestor de elementos de red
EM, que gestiona en ese momento el elemento de red NE, una solicitud
al elemento de red NE, que da lugar a que el elemento de red NE
desconecte el enlace actual con el gestor de elementos de red EM.
Para desconectar el enlace pueden utilizarse procedimientos en sí
conocidos. A continuación establece el elemento de red NE en base a
la solicitud por parte del gestor de elementos de red EM un nuevo
enlace con el centro de gestión de red NMC. También pueden
utilizarse para establecer el enlace procedimientos en sí
conocidos. Según ello, regula el centro de gestión de red NMC con
ayuda de un mecanismo de filtrado existente en el elemento de red
NE la llamada función "event reporting" (informe de sucesos)
del elemento de red NE. Para ello pueden utilizarse por ejemplo en
una interfaz de gestión basada en CMIP los llamados comandos
"M-CREATE" para generar los llamados "Event
Forwarding Discriminator" (discriminador de reenvío de sucesos) o
bien en una interfaz de gestión basada en CORBA las llamadas
órdenes "subscribe" (abonarse), para generar los llamados
"subscription filters" (filtros de abonado). A continuación se
envían las alarmas generadas por el elemento de red NE desde el
mismo directamente utilizando el primer modelo de objetos MODEL1 al
centro de gestión de red NMC. Para una determinada causa de error
es así idéntica desde el punto de vista del centro de gestión de
red NMC la alarma recibida para ambas configuraciones según la
figura 1a y 1b.
Las optimizaciones o ampliaciones de redes de
telecomunicaciones existentes, exigen a menudo modificaciones de la
configuración de la red. Puesto que tales cambios de configuración
usualmente afectan también a parámetros específicos del fabricante,
cuya modificación sólo puede realizarla el gestor de elementos de
red EM, por ejemplo mediante un OMC, es necesaria una conmutación
del elemento de red NE al modo EM. Entonces se ejecutan los
siguientes pasos: primeramente envía el centro de gestión de red NMC
una solicitud al elemento de red NE de desconectar el enlace entre
el centro de gestión de red NMC y el elemento de red NE. Una vez
realizada la desconexión de este enlace, establece el elemento de
red NE, en base a la solicitud recibida del centro de gestión de
red NMC, un nuevo enlace con el gestor de elementos de red EM. El
gestor de elementos de red EM inicia a continuación, con ayuda de
un mecanismo de filtrado generado en el elemento de red NE, la
llamada función "Event Reporting" (informe de sucesos) y envía
a continuación órdenes de configuración al elemento de red NE. El
elemento de red NE ejecuta las órdenes recibidas del gestor de
elementos de red EM y retransmite los resultados y notificaciones
referidas a la configuración, como por ejemplo en CORBA
"objectCreation" (creación de objeto), "objectDeletion"
(borrado de objeto), "attributeValueChange" (cambio de valor de
atributo), al gestor de elementos de red. Para ello se utiliza el
segundo modelo de objetos MODEL2. En el gestor de elementos de red
EM se convierten las notificaciones recibidas del elemento de red NE
al primer modelo de objetos MODEL1 y se retransmiten al centro de
gestión de red NMC. Tras finalizar esta fase de configuración, puede
conmutarse el elemento de red NE, tal como antes se ha descrito, de
nuevo al modo NM.
Ambos procesos de conmutación, es decir, del
modo EM al modo NM y viceversa, son iniciados en cada caso por el
gestor con el que en ese momento está conectado el elemento de red
NE cuando éste envía una solicitud de conmutación al elemento de
red NE. La conmutación entre las formas de funcionamiento se realiza
durante el funcionamiento de la red de gestión. Para los procesos
de conmutación descritos es competente en el elemento de red el
equipo INTERFACE HANDLER (gestor de interfaz). Este recibe las
solicitudes descritas de cambio del modo de servicio del gestor de
elementos de red EM o del centro de gestión de red NMC y procesa las
mismas tal como antes se ha descrito, interrumpiendo o bien
estableciendo enlaces con gestores y originando la utilización del
modelo de objetos adecuado en cada caso. Para ello puede presentar o
bien establecer el equipo INTERFACE HANDLER (gestor de interfaz) un
enlace tanto con los elementos MEANS MODEL1 (modelo de medios 1)
como también con los elementos MEANS MODEL2 (modelo de medios 2) y
con ello controlar estos elementos.
Es ventajoso que en el elemento de red NE exista
un equipo que realice la reproducción de una notificación de uno de
los modelos de objetos en una notificación del respectivo otro
modelo de objeto. Así es posible por ejemplo que notificaciones
del elemento de red NE se generen básicamente según el modelo de
objetos MODEL2 de la interfaz entre el gestor de elementos de red
EM y el elemento de red NE. Si se encuentra el elemento de red NE
en el modo NM, entonces el equipo INTERFACE HANDLER detecta esto y
origina, cuando exista una notificación a enviar al centro de
gestión de red NMC, una conversión de esta notificación al primer
modelo de objetos MODEL1 de la interfaz con el centro de gestión de
red NMC. Además es posible que las órdenes recibidas en el elemento
de red NE puedan o deban ser procesadas exclusivamente en uno de
los modelos de objetos MODEL1 o MODEL2. Así puede por ejemplo
procesarse directamente una orden recibida por el gestor de
elementos de red EM del segundo modelo de objetos MODEL2, mientras
una orden recibida por el centro de gestión de red NMC según el
primer modelo de objetos MODEL1 se somete antes de seguir
procesándose primeramente a una conversión al segundo modelo de
objetos MODEL2. Un equipo como el indicado para la reproducción o
bien conversión entre ambos modelos de objetos MODEL1 y MODEL2
puede estar configurado como aquel equipo que realiza el mapeado o
bien la reproducción en el gestor de elementos de red EM en la
configuración según la figura 1a.
La utilización del procedimiento descrito es
especialmente ventajosa porque la vigilancia de alarmas de un
sistema de comunicaciones de telefonía móvil por razones de coste se
desplaza cada vez más de los gestores de elementos de red a los
centros de gestión de red. Especialmente por las noches o en el fin
de semana es deseable no tener que ocupar los gestores de elementos
de red con personal. Por otro lado, se siguen necesitando los
gestores de elementos de red para la gestión de los elementos de
red, ya que determinadas actividades específicas del fabricante,
como por ejemplo gestión de la configuración referida al hardware,
sólo pueden ser ejecutadas por el correspondiente OMC específico
del fabricante. Mediante el procedimiento correspondiente a la
invención pueden compaginarse ambas exigencias a la red de gestión.
El procedimiento correspondiente a la invención es independiente de
los protocolos de comunicaciones utilizados para las distintas
interfaces.
Aunque el procedimiento se ha descrito en base a
dos modelos de objetos MODEL1 y MODEL2 y correspondientemente a dos
modos del agente, puede aplicarse sobre una cantidad mayor de
interfaces distintas, entre las que ha de realizarse una
conmutación. La solicitud de un gestor que controle en ese momento
