Group message based carrier aggregation control
First Claim
1. A method, by a node in a mobile communication network, of controlling aggregation of component carriers from a first spectrum that is assigned to the mobile communication network and a second spectrum that is not assigned to the mobile communication network, the method comprising:
- allocating at least one component carrier from the second spectrum to a group of mobile terminals that are using component carriers from the first spectrum and that are allowed to use component carriers from the second spectrum; and
in response to detecting that a primary user of the second spectrum requires usage of the at least one component carrier from the second spectrum, transmitting a group message on at least one component carrier from the first spectrum to the group of mobile terminals that are allowed to use the component carriers from the second spectrum, wherein the at least one component carrier from the second spectrum is already allocated to the group of mobile terminals that are using the component carriers from the first spectrum and that are allowed to use the component carriers from the second spectrum, andwherein said group message controls operation of the mobile terminals of the group of mobile terminals that are allowed to use the component carriers from the second spectrum to deactivate the usage of the at least one component carrier from the second spectrum.

Abstract
A mobile communication system includes a network based aggregation controller for controlling aggregation of component carriers from a first spectrum and a second spectrum. In addition, the mobile communication system includes a group of mobile terminals. The network based aggregation controller is configured to send a group message on at least one component carrier of the first spectrum to the group of mobile terminals. The mobile terminals receive the group message. A terminal based aggregation controller in each of the mobile terminals is configured to control operation of the respective mobile terminal with respect to the at least one component carrier of the second spectrum. This control is accomplished in response to the received group message.

14. A method of controlling aggregation of component carriers from a first spectrum and a second spectrum, the method comprising:
-
transmitting a group message on at least one component carrier from the first spectrum to a group of mobile terminals, wherein said group message controls operation of the mobile terminals of the group of mobile terminals with respect to at least one component carrier from the second spectrum; determining if a mobile terminal, not yet assigned to the group of mobile terminals, is at an edge of a coverage region of the second spectrum and further determining one or more of; if the mobile terminal is moving at a velocity above a threshold and if the mobile terminal is moving in a direction towards outside the edge of the coverage region of the second spectrum; and not assigning the mobile terminal to the group of mobile terminals in response to; determining that the mobile terminal is at the edge of the coverage region of the second spectrum, and further determining one or more of; that the mobile terminal is moving at the velocity above the threshold and that the mobile terminal is moving in the direction towards outside the edge of the coverage region of the second spectrum.
