Provision of services via an information technology network
First Claim
1. A method of communication between first and second information devices, comprising the steps of:
- initiating communication between the devices by alerting one of the devices to the presence of another;
passing at least one message between the devices to provide to the first device the address within an information technology network of a second proxy entity for the second device;
connecting the first device to a first proxy entity for the first device, and passing to the first proxy the address within the network of the second proxy;
passing messages between the first and second proxies to establish at least one parameter governing data exchange between the first and second devices; and
conducting communication between the first and second devices in accordance with the at least one parameter by passing messages at least directly between the devices.

Abstract
Information services may be provided to a user of a personal digital assistant (PDA) via an infra red wireless communication port. The PDA recruits communication with a peer, such as a beacon, via this link, and the PDA and peer exchange messages containing the URLs of their proxies within the Internet. The proxies contact each other and negotiate, via the exchange of XML documents, parameters governing exchange of messages via the infra red link, such parameters being related inter alia to technical aspects of communication (e.g. file size, software compatibility etc.), encryption (e.g. public key information), and policy, which determines what the IR wireless link may be employed for, such as what content is sought. Negotiation between proxies is relatively rapid due to the higher bandwidth of the link between them in comparison to the IR link.

24. A method of wireless communication between first and second information devices comprising the steps of:
-
passing at least a message between the devices via a wireless communication link, the message indicating an address within a network of a first proxy entity for the first device;
exchanging messages between the first proxy and a second proxy entity for the second device to determine at least one parameter governing communication between the devices using the wireless link; and
conducting communication between the devices via the wireless link in accordance with the at least one parameter.

33. A method of providing a proxy service to an information device in an information technology network comprising the steps of:
-
registering with a first proxy at least a first information device, including storing at least one parameter related to operative capability of the first information device;
negotiating with a second proxy acting on behalf of a second information device to establish at least one parameter governing interaction between the first and second information devices; and
sending to the first information device from the first proxy the at least one parameter established during the negotiation. - View Dependent Claims (34, 35, 36, 37)
