Description

technical field

[0001] The invention relates to the field of communication technology voice calls, in particular to a method for canceling a number set as a call forwarding number and core network equipment. Background technique

[0002] In order to make it convenient for users to answer incoming calls in some cases, but do not want to miss these incoming calls, users can generally register the call forwarding service on the network side. Call forwarding number.

[0003] The opening of the call forwarding service is unilaterally initiated by the user on the network side.
