KR970031560A - METHOD FOR CANCEL SESSION RELEASE IN DSM-CC PROTOCOL - Google Patents

Abstract

The present invention relates to a method for releasing a client initiated session, which enables a client to easily initiate a session release initiated by a client in the DSM-CC protocol. In the first step of authorizing to the network, if it is determined that the message received from the client is a "client release cancellation request" message, and if the client release cancellation request message, the first step of forwarding a "server release cancellation instruction" message from the network to the server; After step 2 and step 2, determining whether the message received from the network to the server is a "server release cancellation instruction" message, and if the server release cancellation instruction message, determining whether the server can "release session". If "cancel cancel session" is not possible by Step 3, the server is decommissioned. Sending a message notifying that the cancellation has not been made to the network, whereas, if the "cancel cancel session" is possible by the third step, canceling the session release of the server and sending a message notifying the cancellation to the network; After step 4, if it is determined in step 5 that the server release cancellation response message has been delivered from the server to the network, in step 5, the server release cancellation response message has been delivered, In the sixth and sixth steps of determining whether the "session release" of the server has been canceled, if it is determined that "session release" has not been canceled, a message informing the network that the "session cancellation cancellation" has not been made is received. Transmits to the client and, on the contrary, if the "cancel cancel session" is canceled, cancel the session cancel on the network, and then send a message informing the cancellation. By including a seventh step of transmitting to the client because there is no command for releasing the session by the client initiation, it was supplemented with the server network and disadvantages to break down significantly the use of time and resources between the client previously.

Claims (1)

In a communication method using a message from a client to a server through a network, the client may send a "client cancel cancellation request" message to the client in response to a session request to be canceled. A first step of applying to a network; Determining whether the message received from the client is a "client release cancellation request" message, and if a client release cancellation request message, transferring a "server release cancellation instruction" message from the network to a server; After the second step, determining whether the message transmitted from the network to the server is a "server release cancellation instruction" message, and if the server release cancellation instruction message, the third step of determining whether the server can cancel session release; Wow; If "cancellation cancel" is not possible by the third step, a message is sent to the network informing that the server is not canceled. On the other hand, if "cancellation cancel" is enabled by the third step, Canceling the session release and sending a message informing the cancellation to the network; After the fourth step, a fifth step of determining whether a "server release cancellation response" message has been received from the server; A sixth step of determining whether the "session release" of the server has been canceled if it is determined in the fifth step that the "server release cancellation response" message has been delivered; As a result of the determination in the sixth step, if it is determined that "session release" has not been canceled, a message informing that the "session cancellation cancellation" has not been sent is transmitted from the network to the client, and conversely, if the "session cancellation cancellation" And a seventh step of canceling the session release on the network, and then sending a message informing the cancellation to the client. ※ Note: The disclosure is based on the initial application.
