METHOD FOR RESTRICTING PUSH-TO SERVICE

摘要

A method for restricting a push-to (PT) service restricts a PT service with reference to network information. A PT client inviting to a PT session restricts an invited PT client by setting a network dependent outgoing session barring flag as 'ON'. A PT client invited to the PT session restricts the inviting PT client by setting a network dependent incoming session barring flag as 'ON'. The inviting PT client or the invited PT client can be selectively restricted by using information on operation conditions under which the flags are operated.
