Processing method and device for reducing IMS end-to-end association difficulty, equipment and storage medium

The invention relates to a processing method and device for reducing IMS end-to-end association difficulty, equipment and a storage medium. The method comprises the following steps: establishing a data structure comprising a corresponding relationship between a first associated KEY and a second associated KEY carried in an interface and a calling long number and a called long number; maintaining a corresponding relation table of the associated KEY and the long number according to the received SIP call record; when receiving SIP data and judging that a calling number and a called number are short numbers, sequentially extracting a first associated KEY and a second associated KEY corresponding to the short numbers in an IMS network calling service process, and obtaining a long number corresponding to the short numbers from the relation table to complete the short numbers; and carrying out IMS end-to-end association through the complemented long number. The problem of non-uniform distribution caused by non-unifo
