Packet radio transmission over an unlicensed-radio access network
First Claim
1. An unlicensed-radio access network connected to a packet service node in a core network portion of a licensed mobile network, said unlicensed-radio access network comprising:
- an access controller connected to said core network portion and having a packet controller,a fixed broadband network connected to said access controller and having a plurality of access points,each said access point defining a mini-cell coverage area and supporting an unlicensed-radio interface permitting communication of packet data between mobile stations located within a respective mini-cell and said access controller,wherein said access controller comprises a database configured to store temporary identification information assigned to mobile stations for use in packet service messages in association with packet path information addressing said mobile station on said fixed broadband network, andwherein said access controller is configured to receive from said core network portion multiple packet data messages each containing said temporary identification information of a mobile station located in the associated location area, to retrieve the packet path address associated with said identified mobile station, and to transmit each said packet data message to said identified packet path address.

Abstract
An unlicensed-radio access network is connected to a packet service node in a core network portion of a licensed mobile network. The unlicensed-radio access network includes an access controller connected to the core network portion and having a packet controller, a fixed broadband network connected to the access controller and having a plurality of access points. Each of the access points defines a mini-cell coverage area and supports an unlicensed-radio interface permitting communication of packet data between mobile stations located within a respective mini-cell and the access controller. The access controller comprises a database for storing the identification of mobile stations in association with packet path information addressing said mobile station on the fixed broadband network.

10. A method in an unlicensed-radio access network comprising a plurality of access points adapted to communicate with mobile stations over an unlicensed-radio interface and an access controller connected to said access points and to a packet service node in a core network portion of a licensed-radio cellular network, said method including the steps of:
-
receiving from a mobile station a temporary logical link identifier (TLLI) for use in packet service messages specific to said mobile station, registering said temporary logical link identifier in said access controller in association with packet path information identifying at least one access point, receiving in said access controller a packet service message from said core network portion addressing a mobile station, retrieving said temporary logical link identifier from said packet service message; identifying a packet path address to at least one access point for said addressed mobile station, and forwarding said packet service message to the at least one access point identified in association with said registered temporary logical link identifier. - View Dependent Claims (11)

12. A method in an unlicensed-radio access network comprising a plurality of access points adapted to communicate with mobile stations over an Unlicensed-radio interface and an access controller connected to said access points and to a packet service node in a core network portion of a licensed-radio cellular network, said method including the steps of:
-
receiving from a mobile station a temporary logical link identifier (TLLI) for use in packet service messages specific to said mobile station, registering said temporary logical link identifier in said access controller in association with packet path information identifying at least one access point, setting a timer on receipt from a mobile station of a packet service message containing a stored temporary logical link identifier, resetting said timer if a further packet service message containing said stored temporary logical link identifier is received from said mobile station within a predetermined time delay, and deleting said temporary logical link identifier registered for said mobile station if no further packet service message containing said stored temporary logical link identifier is received from said mobile station within said predetermined time delay.

13. A method in an unlicensed-radio access network comprising a fixed broadband network with plurality of access points, and an access controller connected to said fixed broadband network and to a packet service node of a core network portion of a licensed-radio cellular network, the access controller configured to exchange packet service messages with mobile stations over an unlicensed-radio interface via said access points, said method including the steps of:
-
said access controller establishing communication with a mobile station using a network address on said fixed broadband network for said mobile station, receiving temporary identification information for use in packet service messages specific to a mobile station from said mobile station, registering said mobile station identification information in association with a network address on said fixed broadband network specific to said mobile station, retrieving said temporary identification information from a packet data message received from said core network, and directing said packet data message to said network address stored in association with said temporary identification information. - View Dependent Claims (14, 15)

16. An access controller for forming part of an unlicensed-radio access network and for controlling access to the core network portion of a licensed mobile network, said access controller being configured to connect to said core network portion and to a broadband network that has a plurality of access points, each said access point defining a mini-cell coverage area and supporting an unlicensed-radio interface permitting communication of packet data between mobile stations located within a respective mini-cell and said access controller, said access controller further including a packet controller,
wherein said access controller comprises a database for storing temporary identification information assigned to mobile stations for use in packet service messages in association with packet path information addressing said mobile station on said fixed broadband network, and wherein said access controller is further configured to: -
retrieve said temporary identification information from each of multiple packet data messages received from said core network, and direct each said packet data message to a mobile station at said network address stored in association with said temporary identification information. - View Dependent Claims (17, 18, 19, 20)
