Abstract
A method and system for limiting redirections of a mobile station (MS) in an unlicensed radio access network having a plurality of unlicensed network controllers (UNCs). The MS includes a redirection counter set to zero within a registration request sent to one of the UNCs. Each time the MS receives a redirection response from a UNC, the MS increments the redirection counter and sends it in another registration request. Once the redirection counter has exceeded a defined value for the MS, the UNC rejects any registration request from that MS.

A method in a mobile station for limiting redirections of the mobile station between a plurality of unlicensed network controllers (UNCs) in an unlicensed radio access network, the method comprising the steps of:
- (a) setting a value of a redirection counter in the mobile station to zero;
- (b) sending a first registration request from the mobile station to a first UNC, the registration request including the redirection counter value set to zero;
- (c) receiving by the mobile station, a redirection response from the first UNC redirecting the registration request to a different UNC;
- and
- in response to receiving the redirection response:
- (d) incrementing the redirection counter value by the mobile station;
- and
- (e) sending an additional registration request from the mobile station to the different UNC, the additional registration request including the redirection counter value set to the incremented value.
A method in an unlicensed network controller (UNC) for limiting redirections of a mobile station between the UNC and other UNCs in an unlicensed radio access network, the method comprising the steps of:
- receiving a registration request from the mobile station, the registration request including a redirection counter value indicating a total number of times the mobile station has been instructed to redirect to a different UNC;
- determining by the UNC, whether the redirection counter value received in the registration request exceeds a threshold value;
- processing the registration request by the UNC when the redirection counter value does not exceed the threshold value;
- and
- sending a rejection response from the UNC to the mobile station when the redirection counter value exceeds the threshold value.
A computer program embodied on a non-transitory computer readable medium in a mobile station for limiting redirections of the mobile station between a plurality of unlicensed network controllers (UNCs) in an unlicensed radio access network, the computer program comprising:
- a first code segment for setting a value of a redirection counter in the mobile station to zero;
- a second code segment for sending a first registration request from the mobile station to a first UNC, the registration request including the redirection counter value set to zero;
- and
- a third code segment for:
- detecting that the mobile station has received a redirection response from the first UNC that redirects the registration request to a different UNC;
- incrementing the redirection counter value;
- and
- sending an additional registration request from the mobile station to the different UNC, the additional registration request including the redirection counter value set to the incremented value.
A computer program embodied on a non-transitory computer readable medium in an unlicensed network controller (UNC) for limiting redirections of a mobile station between the UNC and other UNCs in an unlicensed radio access network, the computer program comprising:
- a first code segment for receiving a registration request from the mobile station, the registration request including a redirection counter value indicating a total number of times the mobile station has been instructed to redirect to a different UNC;
- a second code segment for determining whether the redirection counter value received in the registration request exceeds a threshold value;
- a third code segment for processing the registration request when the redirection counter value does not exceed the threshold value;
- and
- a fourth code segment for sending a rejection response from the UNC to the mobile station when the redirection counter value exceeds the threshold value.
A mobile station configured to limit redirections of the mobile station between a plurality of unlicensed network controllers (UNCs) in an unlicensed radio access network, the mobile station comprising:
- a processor for controlling operations of the mobile station;
- and
- a non-transitory computer readable medium, accessible by the processor, for storing computer program instructions, wherein when the processor executes the computer program instructions, the processor causes the mobile station to perform the steps of:
- (a) setting a value of a redirection counter in the mobile station to zero;
- (b) sending a first registration request from the mobile station to a first UNC, the registration request including the redirection counter value set to zero;
- (c) receiving by the mobile station, a redirection response from the first UNC redirecting the registration request to a different UNC;
- and
- in response to receiving the redirection response:
- (d) incrementing the redirection counter value by the mobile station;
- and
- (e) sending an additional registration request from the mobile station to the different UNC, the additional registration request including the redirection counter value set to the incremented value.
An unlicensed network controller (UNC) for limiting redirections of a mobile station between the UNC and other UNCs in an unlicensed radio access network, the UNC comprising:
- a processor for controlling operations of the UNC;
- and
- a non-transitory computer readable medium, accessible by the processor, for storing computer program instructions, wherein when the processor executes the computer program instructions, the processor causes the UNC to perform the steps of:
- receiving a registration request from the mobile station, the registration request including a redirection counter value indicating a total number of times the mobile station has been instructed to redirect to a different UNC;
- determining whether the redirection counter value received in the registration request exceeds a threshold value;
- processing the registration request when the redirection counter value does not exceed the threshold value;
- and
- sending a rejection response to the mobile station when the redirection counter value exceeds the threshold value.
