Abstract: In accordance with an improved call routing methodology, a call is routed within a communication network by reference to one or more databases. In response to receiving a local number portability request at a service control point (SCP), the SCP accesses one or more databases to determine whether or not to apply custom call routing to a call directed to a called telecommunications number.

The cipher information is decrypted back to the original information in response to the generated encryption key and the generated second initial vector. The receiving apparatus compares the received first initial vector and the generated first initial vector to check whether or not encryption/decryption-related synchronization between the sending apparatus and the receiving apparatus is normally maintained.
