Abstract
In order to indicate a numbering plan to be used, an indicator is defined, by which a subscriber can indicate whether the subscriber's home numbering plan (203) or a serving network numbering plan (206) is used when routing a call. The indicator preferably indicates the use of the home numbering plan, in which case a telephone number without an indicator uses the serving network numbering plan.
Claims21
A method of selecting a numbering plan to be used in routing a call of a subscriber in a telecommunication system, in which at least a home numbering plan defined in the subscriber's home network and a serving network numbering plan are used;
- characterized by the method comprising the following steps:
- defining a first indicator, by which it is indicated that the home numbering plan defined in the subscriber's home network is used in the call;
- receiving from the subscriber a telephone number associated with a call establishment request;
- in response to a telephone number with the first indicator, using the home numbering plan to route the call;
- and
- in response to a telephone number without an indicator, using the numbering plan of the network serving the subscriber to route the call.

- characterized by the method comprising the following steps:
- defining a first indicator, by which it is indicated that the numbering plan of the network serving the subscriber is used in the call;
- receiving from the subscriber a telephone number associated with a call establishment request;
- in response to a telephone number with the first indicator, using the serving network numbering plan to route the call;
- and
- in response to a telephone number without an indicator, using the home numbering plan defined in the subscriber's home network to route the call.

- in which telecommunication system (1) at least a home numbering plan defined in the subscriber's home network and a serving network numbering plan are used,
- characterized in that the system (1) is arranged to
- check whether a telephone number received by the user equipment from the subscriber contains an indicator;
- identify a first indicator, by which it is indicated that the home numbering plan defined in the subscriber's home network is used when routing a call;
- in response to the first indicator, use the home numbering plan defined in the subscriber's home network to route the call;
- and
- in response to a telephone number without an indicator, use the numbering plan of the network serving the subscriber to route the call.
A telecommunication system (1) comprising:
- at least one unit of user equipment (UE) of a subscriber,
- the subscriber's home network (HN) comprising at least one network node (CSCF_H) arranged to route calls, and
- at least one visited network (VN) serving the subscriber, comprising at least one network node (CSCF_V) arranged to route calls,
- in which telecommunication system (1) at least a home numbering plan defined in the subscriber's home network and a serving network numbering plan are used,
- characterized in that the system (1) is arranged to
- check whether a telephone number received by the user equipment (UE) from the subscriber contains an indicator;
- identify a first indicator, by which it is indicated that the numbering plan of the network serving the subscriber is used when routing a call;
- in response to the first indicator, route the call by using the numbering plan of the network serving the subscriber;
- and
- in response to a telephone number without an indicator, route the call by using the home numbering plan defined in the subscriber's home network.
A network node which is arranged to route a call of a subscriber in a telecommunication system, in which at least a home numbering plan defined in the subscriber's home network and a serving network numbering plan are used and in which telecommunication system a telephone number to be transmitted to the network contains an indicator, by which the type of a telephone number is indicated, characterized in that the network node (CSCF_V, CSCF_H) is arranged to
- identify a first indicator, by which it is indicated that the home numbering plan defined in the subscriber's home network is used in the call;
- and
- in response to the first indicator, route the call by using the home numbering plan defined in the subscriber's home network.
A network node which is arranged to route a call of a subscriber in a telecommunication system, in which at least a home numbering plan defined in the subscriber's home network and a serving network numbering plan are used, characterized in that the network node (CSCF_V, CSCF_H) is arranged to
- check whether a telephone number associated with a call establishment request contains an indicator;
- identify a first indicator, by which it is indicated that the home numbering plan defined in the subscriber's home network is used in the call;
- in response to the first indicator, route the call by using the home numbering plan defined in the subscriber's home network;
- and
- in response to a telephone number without an indicator, route the call by using the numbering plan of the network serving the subscriber.
A network node which is arranged to route a call of a subscriber in a telecommunication system, in which at least a home numbering plan defined in the subscriber's home network and a serving network numbering plan are used, characterized in that the network node (CSCF_V, CSCF_H) is arranged to
- check whether a telephone number associated with a call establishment request contains an indicator;
- identify a first indicator, by which it is indicated that the numbering plan of the network serving the subscriber is used in the call;
- in response to the first indicator, route the call by using the numbering plan of the network serving the subscriber;
- and
- in response to a telephone number without an indicator, route the call by using the home numbering plan defined in the subscriber's home network.
User equipment (UE), which is arranged to forward a telephone number associated with a call establishment request of a subscriber using the user equipment in a telecommunication system, in which at least a home numbering plan defined in the subscriber's home network and a serving network numbering plan are used, which telephone number to be transmitted to the network contains a type indicator, by which the type of the telephone number is indicated,
- characterized in that the user equipment (UE) is arranged to
- check whether the telephone number associated with the call establishment request contains an indicator;
- identify a first indicator, by which it is indicated that the home numbering plan defined in the subscriber's home network is used when routing a call;
- in response to the first indicator, associate the telephone number to be transmitted to the network with a first type indicator which indicates to the network that the call is routed by using the home numbering plan defined in the subscriber's home network;
