Problems solved by technology

Although the SIM-ME interface specification 51.011 (V4.1.0) and USIM application specification 31.102 (V4.0.0) after 3GPP R4 have added the file EF used to save the user's call transfer status CFIS (Elementary File of Call Forwarding IndicationStatus, which contains the basic file of call forwarding indication status), but because this file is an optional file, some SIM cards and USIM cards produced according to these specifications may still fail to support EF CFIS file instead of recording the user's unconditional call forwarding status
[0017] In addition, when the mobile terminal detects that the current subscriber identity card is different from the previous subscriber identity card or the current subscriber identity card is the first subscriber identity car

Embodiment Construction

[0049] Now, the present invention will be described in detail in conjunction with specific embodiments and related drawings.

[0050] Fig. 2 is a flowchart of the first embodiment of the present invention. As shown in FIG. 2, in step S201, the terminal reads attribute information in the current user identification card. Wherein, the terminal has an internal memory for storing attribute information of at least one user identification card, the internal memory may be NVRAM, the user identification card may be a SIM card or a USIM card, and the attribute information of each user identification card may include user identification, The security parameters of the user identification card when it was last applied to the terminal, the location information of the user identification card when it was last applied to the terminal, and the service status corresponding to the user identification card, and the attribute information will not be deleted when the terminal is turned off clear...

Abstract

This invention provides a method for indicating service state to terminals including: a terminal reads the attribute information in a current user ID card and judges if the attribute information of the current ID card of the user is the same with that of one user ID card in all user ID cards kept in an internal storage of said terminal to determine if the current user ID card carries out service process or signaling process in the network system by other access mode or other terminals in the time when it is used in said terminal last time and the terminal this time to decide to indicate the service state in the stored attribute information to users, or decides to enquire the service state corresponding to the current user ID card from the network system to indicate the service state to the user.

Description

technical field [0001] The present invention relates to the communication technology, in particular to the technology for the terminal to indicate the service state. Background technique [0002] In existing communication services such as unconditional call forwarding, after a mobile terminal user activates the unconditional call forwarding service, all circuit service calls with the mobile terminal as the called party will directly reach the target terminal set by the unconditional call forwarding service, The mobile terminal cannot receive these calls and has no way of knowing that these calls have occurred. If the mobile terminal cannot remind the user of the current unconditional call forwarding state in some way when the user activates the unconditional call forwarding service, the user may not cancel the unconditional call forwarding service in time because he has not been reminded, resulting in the failure to receive calls. The circuit service call to the mobile term...
