  • receiving, by the first entity, a REFER message including dialog information from the second entity;

    sending, by the first entity, a response message to the received REFER message to the second entity;

    generating, by the first entity, a Re-INVITE message when header information included in the received REFER message indicates an INVITE message and the dialog information is related to the first entity;

    sending, by the first entity, the generated Re-INVITE message to an address of a target which is subject to session integration, wherein the address is included in the header information and corresponds to the third entity; and
