ROAMING ENCODED INFORMATION READING TERMINAL
First Claim
1. A portable encoded information reading (EIR) terminal for incorporation in a data collection system having a plurality of peer EIR terminals and a plurality of interconnected networks including one or more wireless networks, said EIR terminal associated with a home network having an associated address range, said home network being one of said plurality of networks, said EIR terminal configured to provide IEEE 802.11-conformant wireless distribution system services, including association, disassociation, distribution, integration, and re-association, to said peer EIR terminals, said EIR terminal comprising:
- a central processing unit (CPU);
a memory;
an encoded information reading (EIR) device selected from the group consisting of;
a bar code reading device, an RFID reading device, and a card reading device, said EIR device configured to perform one of;
outputting raw message data containing an encoded message, outputting decoded message data corresponding to an encoded message;
at least one wireless communication interface;
wherein said EIR terminal is configured, when roaming from a first network of said plurality of networks to a second network of said plurality of networks, to maintain zero or more active communication sessions with at least one remote host computer using a home address belonging to said associated address range of said home network; and
wherein said EIR terminal is further configured to transmit an agent solicitation message when in communication with a foreign network other than said home network.

Abstract
A portable encoded information reading (EIR) terminal for incorporation in a data collection system having a host computer, a plurality of peer EIR terminals, and a plurality of interconnected networks including one or more wireless networks, can comprise a central processing unit (CPU), a memory, an encoded information reading (EIR) device, and at least one wireless communication interface. The EIR terminal can be associated with a home network and have a home address belonging to the address range associated with the home network. The EIR terminal can participate in one or more communication sessions and exchange messages, at least one of which can include decoded message data corresponding to an encoded message, with the host computer. The EIR terminal can maintain active communication sessions using its home address when roaming between the interconnected networks.
