Description

A system and method for realizing call transfer service linked with short message transfer service

technical field

The invention relates to the communication field, in particular to a system and method for realizing call transfer service linked with short message transfer service.

Background technique

Now the practical application of voice call forwarding service is extremely extensive. In many cases, temporary call forwarding is required, or users with multiple mobile phones need to transfer voice calls to other mobile numbers, especially when the mobile phone is not available. When the phone is turned on, it is necessary to transfer the voice call to the mobile phone users of colleagues or friends around.

Although voice call transfer can transfer calls to surrounding mobile phone users or landlines, it is also necessary to transfer short messages to other mobile phone users during this time period. However, due to various reasons, the short message transfer service has not yet been popularized One of the most important reasons for using it is that after setting voice call forwarding, it is necessary to send text messages or call the operator's customer phone number to register for short message forwarding, which is very inconvenient for users and has a poor experience.

Therefore, how to transfer the short message sent to the user to the mobile phone user whose voice call is transferred when the user activates the voice call transfer service has become a business that major operators are scrambling to promote.
