Wireless gateway, and associated method, for a packet radio communication system
First Claim
1. In a packet radio communication system having a first part operable pursuant to a first packet radio communication scheme having a first protocol and a second part operable pursuant to a second packet radio common scheme, an improvement of apparatus for facilitating communication of packet-formatted data with a mobile node operable pursuant to the second packet radio scheme while utilizing the first protocol, said apparatus comprising:
- a gateway coupled to both the first part and to the second part to receive messages generated selectably at the first part and selectably at the second part, said gateway selectably for initiating a data-related procedure as part of the handoff procedure defined pursuant to the first protocol responsive to selected messages received thereat, the data-related procedure, once completed, permitting routing of packet-formatted data formatted pursuant to the first protocol with the mobile station.

Abstract
Apparatus, and an associated method, for a 3G, cellular communication system having an access network and a core network. The access network is operable pursuant to the cdma2000 the operational specification, and the core network is operable pursuant to the 3GPP architecture using GPRS. A wireless gateway that provides an interworking functionality is provided to permit to the access network to utilize GPRS as a transport layer through which to transport packet-formatted data, thereby to effectuate, for example, multimedia applications over IP.

15. A method for initiating a data related procedure in a packet radio communication system having a first part operable pursuant to a cdma2000 operating protocol and a second part operable pursuant to a GSM/GPRS operating protocol, and a mobile station operable pursuant to the cdma operating protocol, said method comprising:
-
generating an IOS A1 message at the mobile station for communication to the first part of the packet radio communication system;
providing indications of the IOS A1 message to an interworking function, functionally interconnecting the first and second parts, respectively, of the packet radio communication system; and
utilizing the GSM/GPRS operating protocol as a transport layer to perform the GPRS data related procedure.

16. In a method of communicating in a packet radio communication system having a first part operable pursuant to a first packet radio communication scheme having a first protocol and a second part operable pursuant to a second packet radio communication scheme, an improvement of a method for facilitating communication of packet-formatted data with a mobile node operable pursuant to the second packet radio scheme while utilizing the first protocol, said method comprising:
-
detecting, at a gateway coupled to both the first part and the second part, messages selectably generated at the first part and selectably generated at the second part; and
selectably initiating a data-related attach procedure defined pursuant to the first protocol responsive to selected messages received thereat, the data-related procedure, once completed, permitting routing of packet-formatted data, formatted pursuant to the first protocol with the mobile station. - View Dependent Claims (17, 18, 19, 20)
