Abstract
When location registration is requested from a mobile terminal to a second subscriber profile management means of a switch, the second subscriber profile management means carries out a location registration procedure with respect to a first subscriber profile management means of a home location register. A subscriber profile of the mobile terminal is not transmitted from the first subscriber profile management means to the second subscriber profile management means. Accordingly, the amount of transmission of subscriber profiles from the home location register to the switch is reduced, which prevents the traffic from increasing.

A mobile management method for a mobile communications system that comprises a home location register having a first subscriber profile management means for managing location information of a mobile terminal and a subscriber profile of this mobile terminal, and a switch having a second subscriber profile management means for managing the location information and the subscriber profile of the mobile terminal located in an area controlled by the switch, the mobile management method comprising the steps of:
- carrying out location registration in the first subscriber profile management means, without transmitting the subscriber profile from the first subscriber profile management means to the second subscriber profile management means across the system, upon occurrence of a location registration request from the mobile terminal;
- and
- transmitting the subscriber profile of the mobile terminal from the first subscriber profile management means to the second subscriber profile management means upon occurrence of service activation by the mobile terminal or a network as a trigger.
A subscriber profile transmission method for transmitting a subscriber profile of a mobile terminal from a home location register to a switch, comprising the steps of:
- in response to a location registration request from the mobile terminal, transmitting an instruction from the switch to the home location register not to transmit the subscriber profile to the switch;
- and
- upon receiving a service request from the mobile terminal or a network at the switch, causing the home location register to transmit the subscriber profile of the mobile terminal to the switch.
A switch used in a mobile communications system, the mobile communications system including the switch and a home location register having a first subscriber profile management means for managing location information of a mobile terminal and a subscriber profile of the mobile terminal, the switch comprising:
- a second subscriber profile management means for managing the location information and the subscriber profile of the mobile terminal located in an area controlled by the switch;
- and
- an instruction means for instructing the first subscriber profile management means not to transmit a subscriber profile of the mobile terminal to the switch when receiving a location registration request from the mobile terminal and to carry out location registration at the first subscriber profile management means, while instructing the first subscriber profile management means to transmit the subscriber profile of the mobile terminal to the switch upon receiving a service recluest from the mobile terminal or a network.
A home location register used in a mobile communications system that comprises the home location register and a switch having a second subscriber profile management means for managing location information of a mobile terminal located in an area controlled by the switch and a subscriber profile of the mobile terminal, the home location register comprising:
- a first subscriber profile management means for managing the location information and the subscriber profile of the mobile terminal;
- and
- a determination means for determining not to transmit the subscriber profile to the second subscriber profile management means across system until there is a trigger of service activation from the mobile terminal or a network, when location registration is carried out by the second subscriber profile management means with respect to the first subscriber profile management means.
A switch used in a mobile communications system and managing a subscriber profile of a mobile terminal, comprising:
- a service processing unit configured to receive a service request from the mobile terminal;
- a subscriber profile management means for managing the subscriber profile that is transmitted from a home location register to the switch based on the service request;
- and
- an instruction unit configured to, in response to a location registration reciuest from the mobile terminal, to transmit an instruction to the home location register not to transmit the subscriber profile to the switch.
