摘要

A network function is configured to maintain a copy of a session state for an access terminal. The network function is further configured to query a session master to determine whether the session state has changed. The session master is configured to generate a response to the query that enables the network function to update the copy of the session state if the session state has changed. The access terminal may be configured to change the session state at a first network function and send a message to a second network function to indicate that the session state has been changed.
