Abstract
Systems and methods for managing the secure transmission of positioning integrity KPIs and associated information are provided. A network node provides a key configured to decode positioning integrity assistance information. A wireless device can receive encrypted positioning integrity assistance information and use the key to decrypt the information and perform positioning method(s) in accordance with the decrypted positioning integrity assistance information.
Claims22
A method performed by a wireless device, the method comprising:
- receiving, from a network node, a first key configured to decode positioning integrity assistance information;
- receiving encrypted positioning integrity assistance information, wherein the positioning integrity assistance information includes at least one integrity key performance indicator (KPI) for estimating an integrity level associated with an estimated position of the wireless device;
- decrypting the encrypted positioning integrity assistance information using the first key received from the network node;
- and
- performing positioning measurements using the decrypted positioning integrity assistance information, wherein performing positioning measurements includes:
- determining the estimated position of the wireless device;
- and
- estimating the integrity level associated with the estimated position in accordance with the decrypted positioning integrity assistance information.
A wireless device comprising a radio interface and processing circuitry configured to:
- receive, from a network node, a first key configured to decode positioning integrity assistance information;
- receive encrypted positioning integrity assistance information, wherein the positioning integrity assistance information includes at least one integrity key performance indicator (KPI) for estimating an integrity level associated with an estimated position of the wireless device;
- decrypt the encrypted positioning integrity assistance information using the first key received from the network node;
- and
- perform positioning measurements using the decrypted positioning integrity assistance information, wherein performing positioning measurement includes:
- determining the estimated position of the wireless device;
- and
- estimating the integrity level associated with the estimated position in accordance with the decrypted positioning integrity assistance information.
