Reducing user equipment capability messaging received by extraterrestrial base
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 and requesting that carrier aggregation information not be included. The UE then sends a UE capability information message without carrier aggregation information, thereby reducing the UE capability information transmitted between the UE and the EBS.
1 . A method for reducing user equipment (UE) capability messaging received by an extraterrestrial base station comprising:
transmitting one or more reference signals from the extraterrestrial base station;
receiving an attachment request from the UE as a result of the UE failing to connect to a terrestrial base station;
transmitting a capability enquiry message to the UE comprising signaling instructional elements that instruct the UE to send capability information without including carrier aggregation information, wherein the capability enquiry message includes a plurality of questions related to capabilities supported by the extraterrestrial base station, including whether the UE supports a specific band identified in the capability enquiry message; and
receiving a reduced UE capability information message without the carrier aggregation information from the UE, wherein the UE capability information message comprises information related to the specific a single RF band supported by the extraterrestrial base station, and wherein the UE capability information message includes a response either confirming or denying that the UE supports the specific band identified in the capability enquiry message.
2 . The method of claim 1 , wherein prior to sending the attachment request to the extraterrestrial base station, the UE attempts to locate the terrestrial base station for attachment.
3 . The method of claim 2 , wherein the UE utilizes mobile network code (MNC) that provides a ranking of base stations for attachment.
4 . The method of claim 1 , further comprising transmitting a message to the UE indicating it is approved to attach to the extraterrestrial base station and confirming that the UE has attached to the extraterrestrial base station.
5 . The method of claim 4 , wherein extraterrestrial base station communicates with the UE using eNodeB.
6 . A system for reducing user equipment (UE) capability messaging received by an extraterrestrial base station comprising:
the extraterrestrial base station configured to broadcast signals on a single RF band for a single carrier and including one or more computer processing components configured to perform operations comprising:
transmitting one or more reference signals from the extraterrestrial base station;
in response to a UE detecting at least one reference signal from the extraterrestrial base station and as a result of the UE failing to connect to a terrestrial base station, receiving an attachment request from the UE;
transmitting a capability enquiry message to the UE comprising signaling instructional elements that instruct the UE to send capability information without including carrier aggregation information, wherein the signaling instructional elements include a plurality of questions related to capabilities supported by the extraterrestrial base station, including whether the UE supports the single RF band identified in the capability enquiry message; and
receiving a UE capability information message without carrier aggregation information from the UE, wherein the UE capability information message comprises information related to the single RF band supported by the extraterrestrial base station, and wherein the UE capability information message includes a response either confirming or denying that the UE supports the single RF band identified in the capability enquiry message.
7 . The system of claim 6 , wherein the UE is configured to support multiple RF bands and carrier aggregation combinations.
8 . The system of claim 6 , wherein the extraterrestrial base station communicates with the UE using LTE.
9 . The system of claim 6 , wherein the extraterrestrial base station authenticates the UE prior to transmitting the capability enquiry message.
10 . The system of claim 6 , wherein the extraterrestrial base station does not support carrier aggregation.
11 . The system of claim 6 , wherein the UE attaches to the extraterrestrial base station after the extraterrestrial base receives the UE capability information message.
