Embodiment Construction

[0065] "One card with multiple numbers" service refers to the user using a GSM Subscriber Identity Module (SIM) card or Universal Subscriber Identity Module (USIM) card to have two or more Mobile Subscriber Numbers (MSISDN) numbers, one It is called the main MSISDN number (referred to as the main number), and the others are called the secondary MSISDN number (referred to as the secondary number). The main number and the secondary number can independently carry out communication such as voice and SMS. In the present invention, the main number is defined as: the number assigned to the user by the operator to which the user belongs; the secondary number is defined as: the number provided by the operator of the user's roaming place.

[0066] The present invention provides a device and method for realizing one-card-multiple-number service, which mainly includes one or more of the following parts:

[0067] 1) Build a gateway register;

Abstract

The invention discloses a method for realizing a short message service of multi-numbers in a card and a device thereof. The method comprises the following steps: a gateway register is arranged in a mobile communication system; corresponding relationship between a major number and a plurality of minor numbers of a user of multi-numbers in a card is established in the gateway register; when the user of multi-numbers in a card roams in other cities, the user can register in a roaming city through the gateway register. A request message for location update is interacted between a mobile switchingcenter of the roaming city and a home location register by the transmission of the gateway register. The gateway register stores the location information of the user when roaming and automatically assigns a minor number of the roaming city to the user on the basis of the location information; furthermore, when the user of multi-numbers in a card receives and sends the message in the roaming city,the mobile switching center and a message center of the roaming city interact the routing message of the short messages by the transmission of the gateway register. After the routing of the short messages is inquired, the delivery or reception of the short message is completed.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and a short message system for realizing one-card multi-number short message service. Background technique [0002] In a traditional mobile communication network, a GSM Subscriber Identity Module (SIM, GSMSubscriber Identity Module) card or a Universal Subscriber Identity Module (USIM, Universal Subscriber Identity Module) card corresponds to only one mobile subscriber number, namely the MSISDN number ( Mobile Station International ISDN Number). When the user roams to a foreign country or a place at home and abroad, the user uses the same number to answer the call, so the user will generate high international long-distance call charges or domestic long-distance call charges. Correspondingly, if the user roams abroad, the fee for sending and receiving SMS is the international SMS fee. [0003] In order to reduce the user's international roaming call charges or domestic roaming...
