Problems solved by technology

[0004] However, in practical applications, the user often receives the roaming greeting text message sent by the network side after entering the roaming area for a long time, and sometimes even does not receive the roaming greeting text message before leaving the roaming area
Therefore, the roaming greeting system in the prior art cannot notify the user of the roaming location in time, resulting in the phenomenon of delayed notification

Embodiment 1

[0037] The flow chart of the method for prompting the user of the current roaming location provided by Embodiment 1 of the present invention is as follows figure 1 shown, including the following specific steps:

[0038] S101. The smart card acquires LAI (Location Area Id, location area identifier) ​​information in the broadcast information of the base station.

[0039] The broadcast information of the base station carries the LAI. If the location of the mobile terminal changes after roaming, it will receive information broadcast by the base station that has newly arrived in the location area. The mobile terminal submits broadcast information to a smart card through an interface, such as a SIM (Subscriber Identity Module, Subscriber Identity Module) card or a UIM (User Identity Model, Subscriber Identity Module) card. Smart cards usually get LAI information and save it in a 6F7E (EFloci) file.

[0040] S102. The smart card searches for the pre-stored corresponding relationsh...

Embodiment 2

[0064] The process of judging the roaming position on the terminal side can also be realized through the mobile terminal. The specific process is as follows: image 3 shown, including the following steps:

[0065] S301. When starting up, the mobile terminal reads the corresponding relationship between each LAI and the location and the information of the location of the user from the smart card, and stores them.

[0066] S302. After receiving the broadcast information sent by the base station, the mobile terminal acquires the LAI in the broadcast information.

[0067] S303. The mobile terminal compares the currently acquired LAI with the previously acquired LAI; if they are different, perform step S304; if they are the same, perform step S308, and end.

[0068] S304. The mobile terminal searches for the corresponding relationship between each LAI and the attribution, and determines the attribution corresponding to the currently acquired LAI.

[0069] S305. The mobile terminal...

Embodiment 3

[0086] The process of judging the roaming position on the terminal side can also be realized by setting a roaming judging server. The specific process is as follows: Figure 5 shown, including the following steps:

[0087] S501. After receiving the broadcast information sent by the base station, the terminal acquires the LAI in the broadcast information.

[0088] The terminal side may specifically be a mobile terminal on the terminal side or a smart card on the terminal side. For example, the smart card on the terminal side may acquire the LAI in the broadcast information, or the mobile terminal on the terminal side may acquire the LAI in the broadcast information.

[0089] S502. The terminal side sends the acquired LAI to the roaming judging server.

[0090] Specifically, the mobile terminal may send the LAI through the smart card, or the mobile terminal may send the obtained LAI to the roaming judging server.

[0091] S503. The roaming judging server compares the LAI curr...

Abstract

The invention relates to the mobile communication field, and in particular relates to a technology for carrying out roaming greeting on a user and informing the user of roaming positions in time. The invention provides a method for prompting the user of the current roaming position and a mobile terminal and an intelligent card. The method comprises the following steps of: acquiring LAI carried in broadcast messages of a base station by a terminal; searching corresponding relation of all pre-stored LAIs and attaching locations and determining the acquired attaching locations corresponding to the LAIs; prompting the user of the current roaming position when judging that the determined attaching location are different from the pre-stored attaching location of the user, and updating the attaching location of the user as determined attaching location. As the terminal judges that the attaching location of the user changes according to the broadcast of the base station, the user is prompted of the current roaming position, thus avoiding the dependence on a network side for realizing judgment on the roaming situation of the user, being capable of informing the user of roaming positions in time and saving the occupation to the network side resources.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to the technology of roaming greeting and notifying the roaming position to the user in time. Background technique [0002] With the continuous development of communication technology, mobile communication has been widely used. When the user travels to other regions, the mobile terminal of the user can often receive the roaming greeting short message sent by the network side. For example, a common roaming greeting text message is "Welcome to Sanya...". The roaming greeting text message carries the name of the region the user is currently entering, thereby notifying the user of the current roaming location. [0003] In the prior art roaming greeting system, signaling monitoring technology is mainly used: the mobile terminal actively initiates a signaling monitoring request to the network side, and the network side monitors the user location information of the mobile terminal acco...
