Session Initiation Protocol (SIP) and 3GPP TS24 series protocols both stipulate session businesses. The 3GPP TS24 series protocol and a RFC 535 protocol in SIP stipulate that after the blind transfer, terminals that dialogue with each other before the blind transfer will still communicate. Therefore, after receiving a BYE message, session resources before the blind transfer will not be released. However, according to a RFC 3261 protocol, the session resources will be released after receiving the BYE message, which requires special handling of the blind transfer. There are several problems with this:
