Delivery of broadcast teleservice messages over packet data networks
First Claim
1. A communications network comprising:
- a circuit-switched network providing communications services to mobile terminals having service with said circuit-switched network;
a broadcast teleservice message center connected to said circuit-switched network to generate broadcast teleservice messages formatted according to a first messaging protocol for delivery to mobile terminals having service with said circuit-switched network;
a packet-switched network providing communication services to mobile terminals having service with said packet-switched network; and
an interworking function connecting said broadcast teleservice message center to said packet-switched network, said interworking function including a formatter to format broadcast teleservice messages according to said second messaging protocol for delivery over said packet-switched network to mobile terminals having service with said packet-switched network.

Abstract
A communication network comprises a broadcast teleservice message center generating broadcast teleservice messages. The broadcast teleservice message center is connected to a circuit-switched network over an interface that uses a first messaging protocol. The broadcast teleservice message center includes an interworking function to connect the broadcast teleservice message center to a packet-switched network over an interface that uses a second messaging protocol. Broadcast teleservice messages transmitted over said first interface to mobile terminals having service with the said circuit-switched network are converted by the interworking function to a format specified by the second messaging protocol for delivery over the packet-switched network to mobile terminals having service with the packet-switched network.

14. A method for delivering subchannel data transmitted over a circuit-switched network to a mobile terminal having service with a packet-switched network, said method comprising:
-
assigning a group identification number to a service provider for said circuit-switched network;
assigning a group identification number to sub-channels used by said service provider to transmit said sub-channel data;
transmitting said group identification numbers assigned to said sub-channels to mobile terminals registered with said packet-switched network in a first broadcast teleservice message having a group identification field and a data field, said group identification numbers assigned to said sub-channels being contained in said data field, and said group identification number for said corresponding service provider being contained in said group identification field; and
transmitting sub-channel data to mobile terminals registered in said packet-switched network in a second broadcast teleservice message having a group identification field and a data field, said group identification field containing a group identification for a selected sub-channel to identify the sub-channel and said data field containing said sub-channel data.

16. An interworking function connecting a broadcast teleservice message center to a packet-switched network, said interworking comprising:
-
a first interface connecting said interworking function to said broadcast message center, wherein said interworking function receives broadcast teleservice messages formatted according to a first messaging protocol over said first interface;
a formatter to format said broadcast teleservice messages received over said first interface according to a second messaging protocol for delivery to mobile terminals having service with a packet-switched network; and
a second interface connecting said interworking function to said packet witched network, wherein said interworking function transmits said broadcast teleservice messages formatted according to said second messaging protocol to said packet switched network over said second interface.
