A method and a method for controlling a call in a user network interface in an asynchronous transfer mode

摘要

The present invention relates to a call and connection control method at a user network interface in an asynchronous transfer mode, the method comprising: allocating (S1) a memory area for caller sub-address information; Setting an identifier of caller address information in the memory area (S2); Setting an extension, a coding standard, and an information element command field in the memory area (S3); (S4) setting an extension, a sub-address type, and an odd / even indicator in the memory area; Setting (S5) the sender sub-address information in the memory area; Setting (S6) the length of contents of the sender sub-address in the memory area; And outputting a value set in the memory area as a sender sub-address information value (S7), thereby generating sender sub-address information for identifying the sender sub-address.
