Apparatus, and associated method, for integrating operation of packet radio communication systems
First Claim
1. In a method for communicating packet data in a radio communication system having a network infrastructure including a first fixed-site transceiver and at least a second fixed-site transceiver with which a mobile station is selectably connectable by way of a radio link, an improvement of a method for integrating operation of a first packet data system having at least a first packet-data-system element with operation of a second packet data system having at least a second packet-data-system element, thereby to form an integrated system of the packet radio communication system, said method comprising:
- mapping identities of the first and at least second fixed-site transceivers defined in the first packet data system to corresponding identities defined in the second packet data system;
relaying packet data between the first packet-data-system element and a selected one of the first and at least second fixed-site transceivers, the packet data of any selected information-element type of a plurality of element types defined in either of the first packet data system and the second packet data system.

Abstract
Apparatus, and an associated method, forms an integrated packet radio communication system. An integrated system is formed of portions of a GPRS system as well as portions of a WLAN system, such as that defined in the IEEE 802.11 standard. A WIP (WLAN Integrated Protocol) layer is defined, functionally positioned between upper-level, GPRS layers and lower-level, WLAN layers. Advantages of a GPRS system as well as advantages of the WLAN system are maintained in the integrated system.
