Provision of services via an information technology network
First Claim
1. A method of communication between first and second information devices, at least one of which is portable, the method comprising:
- initiating communication between the devices using a first channel of communication having a first speed of data transmission;
using the first channel, passing at least one message between the devices containing data enabling interconnection of the first and second devices via a second channel of communication having a second speed of data transmission, faster than the first speed;
using the second channel to exchange data between the devices to establish ul least one parameter governing data exchange between the devices via the first channel, wherein the second channel of communication includes first and second intermediate entities which route communications from the first and second devices respectively, and the first and second intermediate entities act as proxies for the first and second devices; and
conducting communication between the devices using at least the first channel in accordance with the at least one parameter and relaying messages received by at least one of the devices via the first channel to the proxy of that device.

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.

14. A method of communicating between first and second devices, at least one of which is portable, the method comprising:
-
passing data from one device to another along a first communication link, the data enabling the devices to establish communication via a second link faster than the first link; using the second link to establish at least one parameter governing communication via the first link, wherein the second link of communication includes first and second intermediate entities which route communications from the first and second devices respectively, and the first and second intermediate entities act as proxies for the first and second devices; and communicating via the first link in accordance with the at least one parameter and relaying messages received by at least one of the devices via the first link to the proxy of that device. - View Dependent Claims (15, 16, 17, 18)

19. A method of communicating between first and second devices, at least one of which is portable, the method comprising:
-
passing data from one of the devices to another, along a first communication link, to enable the devices to communicate with each other via a second communication link which has a frequency bandwidth greater than the first link'"'"'s bandwidth; establishing communication between the devices via the second link to establish rules governing communication via the first link, wherein the second communication link of communication includes first and second intermediate entities which route communications from the first and second devices respectively, and the first and second intermediate entities act as proxies for the first and second devices; and communicating via the first link in accordance with the rules, to exchange data relating to content and relaying messages received by at least one of the devices via the first communication link to the proxy of that device. - View Dependent Claims (20, 21, 22, 23, 24)
