Negotiation of control over a PTT call between an OMA PoC network and a P25 network
First Claim
1. A communication network, comprising:
- an Open Mobile Alliance (OMA) Push-to-Talk over cellular (PoC) network having a first Push-to-Talk (PTT) server adapted to serve a calling party;
a Project 25 (P25) network having a second PTT server adapted to serve a called party;
the first PTT server adapted to receive a request for a PTT call from the calling party to the called party, to generate a call initiation message for the PTT call that includes an offer for control over the PTT call to the second PTT server, and to transmit the call initiation message to the second PTT server; and
the second PTT server adapted to receive the call initiation message for the PTT call, to process the call initiation message to identify the offer for control over the PTT call, to determine whether the calling party or the called party has the floor for initial transmission for the PTT call responsive to identifying the offer, to generate a response message that includes an indication as to which one of the calling party or the called party has the floor for initial transmission, and to transmit the response message to the first PTT server.

Abstract
Communication networks and methods are disclosed for negotiating control over a PTT call between an OMA PoC network and a P25 network. If an OMA PoC PTT server receives a request for the PTT call from a calling party, then the PTT server transmits a call initiation message for the PTT call to the P25 network offering control over the PTT call to a PTT server in the P25 network. The P25 PTT server processes the call initiation message to identify the offer for control, assumes control over the PTT call, and determines whether the calling or called party has the floor for initial transmission for the PTT call. The P25 PTT server then transmits a response message to the OMA PoC PTT server indicating which one of the calling or called party has the floor. The party granted the floor may then initiate voice communications for the PTT call.

7. A method of operating an Open Mobile Alliance (OMA) Push-to-Talk over cellular (PoC) network having a first Push-to-Talk (PTT) server adapted to serve a calling party and a Project 25 (P25) network having a second PTT server adapted to serve a called party, the method comprising:
-
receiving a request for a PTT call from the calling party to the called party in the first PTT server; generating a call initiation message for the PTT call in the first PTT server that includes an offer for control over the PTT call to the second PTT server; transmitting the call initiation message from the first PTT server to the second PTT server; processing, in the second PTT server, the call initiation message to identify the offer for control over the PTT call; determining whether the calling party or the called party has the floor for initial transmission for the PTT call responsive to identifying the offer; generating a response message that includes an indication as to which one of the calling party or the called party has the floor for initial transmission; and transmitting the response message from the second PTT server to the first PTT server. - View Dependent Claims (8, 9, 10, 11, 12)

13. A communication network, comprising:
-
a first Push-to-Talk (PTT) network and a second PTT network having different rules for assigning control over PTT calls; the first PTT network adapted to receive a request for a PTT call from a calling party to a called party, and to transmit a call initiation message for the PTT call to the second PTT network that includes an offer for control over the PTT call to the second PTT network; and the second PTT network adapted to receive the call initiation message for the PTT call, to process the call initiation message to identify the offer for control over the PTT call, to determine whether the calling party or the called party has the floor for initial transmission for the PTT call responsive to identifying the offer, and to transmit a response message to the first PTT network that includes an indication as to which one of the calling party or the called party has the floor for initial transmission. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
