Abstract: In one embodiment, a network node is operable, responsive to receiving a request from an enterprise user to initiate origination of an outgoing cellular call to a called party, for establishing a first call leg to the enterprise user by sending a circuit-switched call that identifies an enterprise address of the enterprise user as a calling line identity. The network node includes functionality for establishing a second call leg to the called party upon receiving an indication from the enterprise user that the first call leg has been established. The first and second call legs are then patched to establish an end-to-end communications path between the enterprise user and the called party, wherein the enterprise address instead of the non-enterprise address is presented to the called party as a calling line identity with respect to the outgoing cellular call from the enterprise user.

Abstract: In one embodiment, an IMS network node is operable, responsive to receiving a SIP INVITE request from an enterprise user to initiate origination of an outgoing cellular call to a called party, for establishing a first call leg to the enterprise user by sending a SIP INVITE message back to the enterprise user. The IMS network node includes functionality for establishing a second call leg to the called party. The first and second call legs are patched to establish an end-to-end communications path between the enterprise user and the called party, wherein an enterprise address instead of a non-enterprise address of the enterprise user is presented to the called party as a calling line identity with respect to the outgoing cellular call from the enterprise user.

Abstract: Systems of methods for performing queued and moderated communication groups in a system featuring network provided half duplex communications communication group sessions are provided. According to one aspect, a first mobile terminal provides the network with an identification of a second mobile terminal so that the network may automatically grant the transmit capability to the second mobile terminal after a transmitting mobile has finished transmitting communications.

According to another aspect, priority information is pre-assigned during creation of the communication group or dynamically assigned by another mobile user during the talk group session. Granting of the transmit capability and the time duration of the transmit capability is dependent upon the priority information.
