Method and apparatus for controlling de-subscription of a master device at a base station
First Claim
Patent Images
1. A method of controlling de-subscription in a local wireless telephony system, comprising:
- receiving, at a base station of the local wireless telephony system over a link of a local wireless telephony interface of the base station, a request to operate as a master device from a remote telephony device that is subscribed to the base station;
transmitting a grant to operate as a master device to the remote telephony device from the base station over the local wireless telephony interface and recording an indication at the base station that the remote telephony device is a master device;
receiving a command from the master device at the base station;
determining that the command includes a de-subscription command and includes a de-subscription target device identifier that is the same as a master device identifier of the master device;
resolving a conflict handling process at the base station responsive to determining the de-subscription target device identifier and the master device identifier are the same, wherein the conflict handling process prevents de-subscription of the master device until the conflict handling process is resolved; and
de-subscribing the master device from the base station subsequent to resolving the conflict handling process, performed by the base station.

Abstract
A master device transmits a de-subscription command to a base station with which it is subscribed. The de-subscription command indicates the master device intends to de-subscribe itself, which requires resolution of a conflict handling process. Upon resolution of the conflict handling process, the base station de-subscribes the master device.

11. A base station of a local wireless telephony system, comprising:
-
a controller operable to execute instructions contained in firmware of the base station; a transceiver operably connected to the controller that establishes a local wireless telephony interface; a registry operable to record identifiers of remote telephony device that are subscribed to the base station; wherein the firmware contains instruction code for a conflict handling process that is invoked by the base station upon the base station receiving a de-subscription command from a master device indicating the master device is attempting to de-subscribe itself, and wherein upon successful resolution of the conflict handling process, the base station de-subscribes the master device from the base station. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A method of de-subscribing a remote telephony device operating as a master device from a base station, comprising:
-
receiving a command sequence at the base station from the master device; determining at the base station that the command sequence includes a de-subscription command; determining at the base station that a target identifier of the de-subscription command is the same as an identifier of the master device; resolving a conflict handling process responsive to determining the target identifier of the de-subscription command is the same as the identifier of the master device; and deleting the identifier of the master device from a subscription registry of the base station. - View Dependent Claims (19, 20)

21. A remote telephony device, comprising:
-
a controller; a transceiver operably coupled to the controller and operable to communicate with a base station over a local wireless telephony interface; firmware operably coupled to the controller and containing instruction code for operating the remote telephony device in a master mode; wherein the remote telephony device is configured to, while operating in the master mode, issue a de-subscription command to the base station, the de-subscription command targeting the remote telephony device, upon an indication that the de-subscription command has been granted the remote telephony device is configured to delete an identifier corresponding to the base station from a subscribed base station identifier memory location in the remote telephony device. - View Dependent Claims (22, 23, 24)
