Packet-based services in a push-to-talk system
Abstract
A mechanism and method for initiating a packet-based service session in a public mobile communication system, especially a service session for a group of users are disclosed. In order to accomplish a service initiation even if the terminals of the users are in a disconnected state with respect to the packet-switched domain of the mobile communication system, a triggering message is sent from one user terminal to the other terminals of the group. The triggering message includes information about a packet-based service session to be started, and it may be a message that can be sent via the mobile communication system to a mobile terminal that is in a disconnected state with respect to the packet-switched domain. In response to the reception of the triggering message, the other terminals are brought to a state allowing reception of packets belonging to the packet-based service session. When necessary, this feature involves establishing a connection from the other terminals to the packet-switched domain.
