Abstract

Embodiments of the present disclosure are directed to systems and methods for limiting user equipment (UE) capability information messaging received by an extraterrestrial base station (EBS). One or more broadcast signals are transmitted from the EBS and detected by a UE. Upon detecting the broadcast signals, the UE requests to attach to the EBS. In aspects, the EBS will first authenticate the UE's identity. Then, a capability enquiry message is transmitted to the UE specifying what information the EBS would like (e.g. information limited to the one frequency band supported by the EBS). The UE then sends a UE capability information message comprising only the information requested from the EBS, thereby reducing the UE capability information transmitted between the UE and the EBS.

First claim

What is claimed is:

1 . A system for requesting explicit user equipment (UE) capability information comprising:
an extraterrestrial base station configured to support one frequency band; and one or more computer processing components configured to perform operations comprising: transmitting one or more signals from the extraterrestrial base station to a UE; receiving an attachment request from the UE in response to the UE detecting the one or more signals; transmitting a UE capability enquiry message to the UE instructing the UE to send reduced capability information limited to the one frequency band supported by the extraterrestrial base station; and receiving a reduced UE capability information message comprising capability information related only to the at least one frequency band supported by the extraterrestrial base station.

2 . The system of claim 1 , wherein the one or more computer processing components are further configured to grant permission to the UE to attach to the extraterrestrial base station.

3 . The system of claim 1 , wherein receiving the reduced UE capability information message saves bandwidth resources.

4 . The system of claim 1 , wherein the UE requests to attach to the extraterrestrial base station after determining it cannot attach to a terrestrial base station.

5 . The system of claim 1 , wherein prior to transmitting the enquiry capability message, the identity of the UE is authenticated by the extraterrestrial base station.

6 . The system of claim 5 , wherein authentication of the UE comprises an exchange of information between the UE and the extraterrestrial base station.

7 . The system of claim 1 , wherein the reduced UE capability information message improves the system's capacity.

8 . The system of claim 1 , wherein the reduced UE capability information message decreases the risk of transmitting incorrect information to the extraterrestrial base station.

9 . The system of claim 1 , wherein the extraterrestrial base station supports LTE.

10 . A method for requesting explicit user equipment (UE) capability information comprising:
transmitting one or more signals from an extraterrestrial base station to a UE; receiving an attachment request from the UE; transmitting a UE capability enquiry message to the UE instructing the UE to send reduced capability information limited to a single frequency band supported by the extraterrestrial base station; and receiving a reduced UE capability information message comprising capability information related only to the single frequency band supported by the extraterrestrial base station.

11 . The method of claim 10 , wherein prior to sending the attachment request to the extraterrestrial base station, the UE attempts to locate a terrestrial base station for attachment.

12 . The method of claim 10 , further comprising authenticating the identity of the UE prior to transmitting the UE capability enquiry message.

13 . The method of claim 12 , further comprising transmitting a signal to the UE indicating it is approved to attach to the extraterrestrial base station.

14 . The method of claim 13 , further comprising confirming that the UE has attached to the extraterrestrial base station.

15 . The method of claim 11 , wherein the UE capability enquiry message comprises a plurality of questions related to the UE's capabilities.

16 . The method of claim 14 , wherein the UE responds with either a yes or no to the plurality of questions included in the UE capability enquiry message.

17 . A system for requesting explicit user equipment (UE) capability information comprising:
an extraterrestrial base station supporting a single RF band; and one or more computer processing components configured to perform operations comprising: transmitting one or more reference signals from the extraterrestrial base station to a UE; in response to a UE detecting at least one reference signal from the extraterrestrial base station, receiving an attachment request from the UE; authenticating the identity of the UE; transmitting a capability enquiry message to the UE comprising signaling instructional elements that instruct the UE to respond to a plurality of questions comprising whether the UE supports a specific band identified, whether the UE supports 64QAM, and whether the UE supports Power Class 2; receiving a UE capability information message solely comprising responses to the plurality of questions; and in response to determining that the UE supports the capabilities related to the single RF band supported by the extraterrestrial base station, transmitting a message to the UE allowing the UE to attach to the extraterrestrial base station.

18 . The system of claim 17 , wherein the extraterrestrial base station communicates with the UE using LTE.

19 . The system of claim 17 , wherein the system inquires whether the UE supports the same band as the extraterrestrial base station in the capability enquiry message.

20 . The system of claim 19 , wherein the UE responds either confirming or denying that it supports the same band as the extraterrestrial base station in the UE capability information message.
