Embodiment 1

[0059] figure 1 A schematic flow diagram of a method for establishing a Bluetooth remote access connection between a mobile phone and a car phone according to Embodiment 1 of the present invention, including:

[0060] Step S11: the user turns on the remote access function of the mobile phone. The remote access function of the mobile phone is generally not set to be automatically turned on. When using it, the user needs to turn it on manually. The user can find the corresponding setting menu in the function menu and choose to turn it on.

[0061] Step S12: After the mobile phone receives the remote access start request, it searches for the remote access service, if found, adds the remote access service to the current service record, and activates the remote access server function of the mobile phone. After the user chooses to enable the remote access function of the mobile phone in step S11, the mobile phone will receive a remote access activation request, and then the mobile ...

Embodiment 2

[0068] Figure 4 A schematic flow diagram of a method for establishing a Bluetooth remote access connection between a mobile phone and a car phone according to Embodiment 2 of the present invention, including:

[0069] Step S21: Obtain the information of each SIM card during the power-on process of the SIM card. Wherein, the information of the SIM card includes at least one of the user number corresponding to each SIM card and the network to which each SIM card belongs.

[0070] Step S22: Determine whether the user has turned on the remote access function of the mobile phone. The specific implementation is the same as step S11 in the first embodiment. If the judgment result is yes, execute step S23, otherwise return to step S22.

[0071]Step S23: After the mobile phone receives the remote access activation request, it searches for the remote access service, if found, adds the remote access service to the current service record, activates the remote access server function of...

Embodiment 3

[0077] Figure 6 It is a schematic flow diagram of the method for switching the Bluetooth remote access connection between the mobile phone and the car phone in Embodiment 3 of the present invention, including:

[0078] Step S31: Establishing a Bluetooth remote access connection between the mobile phone and the car phone. The specific implementation of this step can refer to Embodiment 1 or Embodiment 2.

[0079] Step S32: Judging whether the signal quality of the accessed SIM card is lower than the signal threshold and its duration exceeds a preset value. The signal threshold is a threshold value for judging whether to switch the remote access connection between the vehicle phone and the visited SIM card to another SIM card. Specifically, if the received signal quality of the cell where the visited SIM card is located When it is lower than the signal threshold, it means that the accessed SIM card cannot guarantee the service quality of the user even through the external ant...

Abstract

The invention discloses a communication terminal and a method and device for having access to a user identification module of the communication terminal remotely. The communication terminal comprises two or more user identification modules. The method for having access to the user identification module of the communication terminal remotely comprises the steps that when the communication terminal receives a remote access starting request and a remote access service is found, the remote access service is added to current service records, and the remote access server function of the communication terminal is activated; the user identification module to which a client side has access to among all the user identification modules of the communication terminal is determined wherein the user identification module to which the client side has access to is the user identification module which is in communication with the client side having access to the user identification module remotely; remote access connection between the client side and the user identification module to which the client side has access to is established so that the client side can have access to the user identification module remotely. By the adoption of the communication terminal and the method and device for having access to the user identification module of the communication terminal remotely, remote Bluetooth access of the client side to the multi-card communication terminal can be achieved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a communication terminal and a method and device for remotely accessing its user identification module. Background technique [0002] With the rapid development of communication technology, portable communication terminals (such as mobile phones) have become the most widely used communication tools due to their convenience and portability. However, in some application scenarios, the call effect of the communication terminal will be affected by the environment. The power consumption of the communication terminal with poor signal will also increase greatly. When a communication device with an external antenna is installed in the user's place, since the signal of the external antenna will not be attenuated in the user's place, the remote access function of the Subscriber Identification Module of the communication terminal can be turned on at this time, and through the commun...
