How to connect to a mobile device and a communication network

Abstract

According to one embodiment, the described mobile terminal comprises: a receiver configured to receive one or more messages containing propagation environment element information specifying one or more propagation environment elements that are permitted to be used for communication between the mobile terminal and the selected base station for at least one of a plurality of base stations of a radio access network; a controller configured to select one of the base stations depending on the propagation environment element information; and a transmitter configured to send a connection request to the selected base station.

Claims

1. It is a mobile device: A receiver configured to receive one or more messages containing propagation environment element information specifying one or more propagation environment elements, which are one or more objects that affect the propagation of radio waves, for at least one of a plurality of base stations of a radio access network, which is permitted to be used for communication between the mobile terminal and the selected base station; A controller configured to select one of the base stations depending on the propagation environment element information; A transmitter configured to send connection requests to a selected base station, Mobile terminal.

2. The mobile terminal according to claim 1, wherein the controller is configured to select one or more propagation environment elements from a set of propagation environment elements which are permitted to be used for communication between the mobile terminal and a selected base station, and the transmitter is configured to include instructions for the selected one or more propagation environment elements in the connection request.

3. The mobile terminal according to claim 1, wherein the receiver is configured to receive a response to the connection request indicating one or more of the propagation environment elements used for communication between the mobile terminal and a selected base station, and the mobile terminal is configured to use the indicated one or more propagation environment elements for communication with the selected base station.

4. The mobile terminal according to claim 3, wherein the response is a wireless resource control setting message or a wireless resource control restart message.

5. The mobile terminal according to claim 1, wherein the receiver is configured to receive a radio resource control reconfiguration message indicating one or more of the propagation environment elements used for communication between the mobile terminal and a selected base station, and the mobile terminal is configured to use the indicated one or more propagation environment elements for communication with the selected base station.

6. The mobile terminal according to claim 1, wherein the connection request is a wireless resource control setting request message or a wireless resource control restart request message.

7. The mobile terminal according to claim 1, configured to receive messages from each of a plurality of base stations, each containing propagation environment element information that specifies one or more propagation environment elements available for communication between the mobile terminal and the selected base station, or that there are no propagation environment elements available for communication between the mobile terminal and the selected base station.

8. The mobile terminal according to claim 1, wherein the one or more messages indicate the location, type, identification information, dimensions and / or capabilities and / or configuration of the one or more propagation environment elements that are permitted to be used for communication between the mobile terminal and a selected base station.

9. The mobile terminal according to claim 1, wherein the connection request is a wireless resource control request.

10. The mobile terminal according to claim 1, wherein the one or more messages are system information blocks.

11. The mobile terminal according to claim 1, wherein the one or more messages are dedicated system information blocks for providing propagation environment elements to the mobile terminal.

12. The mobile terminal according to claim 1, wherein the one or more propagation environment elements include one or more network-controlled repeaters and / or one or more passive and / or actively programmable metasurface units.

13. A communication system comprising a mobile terminal according to any one of claims 1 to 12, further comprising a plurality of base stations, wherein at least one base station comprises a transmitter configured to transmit one or more of the messages comprising the propagation environment element information.

14. The communication system according to claim 13, wherein each of the plurality of base stations is configured to transmit each of the one or more messages, each containing propagation environment element information, which specifies one or more propagation environment elements that are permitted to be used for communication between the mobile terminal and the selected base station, or which specifies that there are no propagation environment elements that are permitted to be used for communication between the mobile terminal and the selected base station.

15. A method of connecting to a communication network: The steps include receiving one or more messages from at least one base station among a plurality of base stations of a radio access network, which include propagation environment element information specifying one or more propagation environment elements that are one or more objects affecting radio wave propagation and which are permitted to be used for communication between a mobile terminal and the selected base station; The step of selecting one of the base stations depending on the propagation environment element information; The step of sending a connection request to the selected base station and Methods that include...
