Description

Mobile terminal and method for remotely activating call transfer thereof

The present invention relates to the field of communications technologies, and more particularly to a mobile terminal and method for remotely activating call forwarding. Background technique

With the rapid development of communication technologies, mobile terminals (such as mobile phones) have become an indispensable communication tool for people, and they have penetrated into all aspects of life and work, especially SMS and voice services, which are essential functions. widely used. The appearance of mobile phones has indeed brought convenience to people's lives, but it has also had some impacts. For example, when you forget to bring your mobile phone, you may miss important calls from important customers and may not be able to respond to text messages in time. Worried or misunderstood. According to a network survey, most netizens believe that life must not leave the mobile phone. Once the mobile phone is not around, it will unconsciously affect the emotions, for fear of missing important calls and text messages.

In the state of the art, the operator provides a call forwarding service to reduce the leakage of the telephone to a certain extent, but the call forwarding service requires the user to design the transfer mode and the number to be transferred in advance on the terminal, and once The service activation mobile terminal will continue to transfer processing unless the user sends a deactivation command on the terminal. Therefore, for the life scenario where the user temporarily forgets to bring the mobile phone, the call forwarding service provided by the operator is useless. Moreover, the existing transfer function does not apply to SMS services. Summary of the invention
