`
`J. U.S. Patent 8,630,234, Claim 1
`1. A method of roaming with a mobile telephone, the method
`comprising:
`
`[n/a]
`
`[n/a]
`
`and the destination node can be conducted, the access code being
`distinct from the destination node identifier; and
`
`means for causing the wireless apparatus to establish
`communications with the destination node through the
`communications channel identified by the access code in the
`access code reply message, the access code being based on the
`location identifier transmitted in the access code request
`message.
`
`
`J. U.S. Patent 10,880,721, Claim 38
`38. A wireless apparatus comprising:
`
`a processor circuit comprising at least one processor;
`
`a network interface in communication with the processor circuit;
`and

`
`receiving, from a user of the mobile telephone, a callee identifier
`associated with the callee;
`
`
`transmitting an access code request message to an access server
`to seek an access code from a pool of access codes wherein each
`access code in said pool of access codes identifies a respective
`telephone number or Internet Protocol (IP) network address that
`enables a local call to be made to call the callee identified by the
`callee identifier, said access code request message including said
`callee identifier and a location identifier separate and distinctive
`from said callee identifier, said location identifier identifying a
`location of the mobile telephone;
`
`receiving an access code reply message from the access server in
`response to said access code request message, said access code
`reply message including an access code different from said
`callee identifier and associated with said location identifier
`
`a non-transitory computer readable medium having computer
`executable codes stored thereon for directing the processor
`circuit to:
`
`receive from a user of the wireless apparatus a destination node
`identifier associated with a destination node with which the user
`wishes to communicate;
`
`transmit an access code request message to an access server, the
`access code request message including the destination node
`identifier and a location identifier identifying a geographical
`location of the wireless apparatus;
`
`receive an access code reply message from the access server in
`response to the access code request message, the access code
`reply message including an access code based on the location
`identifier in the access code request message, the access code

`K. U.S. Patent 8,630,234, Claim 1
`1. A method of roaming with a mobile telephone, the method
`comprising:
`
`
`receiving, from a user of the mobile telephone, a callee identifier
`associated with the callee;
`
`
`identifying a communications channel on a gateway through
`which communications between the wireless apparatus and the
`destination node can be conducted, the access code being
`distinct from the destination node identifier; and
`
`initiate communications from the wireless apparatus, via the
`network interface, using the access code based on the location
`identifier, to establish communications between the wireless
`apparatus and the destination node through the communications
`channel identified by the access code.
`
`
`K. U.S. Patent 10,880,721, Claim 50
`50. A non-transitory computer readable medium having stored
`thereon computer executable codes for directing a processor
`circuit of a wireless device to establish communications with a
`destination node on a network, the codes comprising codes for
`directing the processor circuit to:
`
`cause the wireless device to receive from a user of the wireless
`device a destination node identifier associated with the
`destination node;
