and receiving a report of one or more evaluated integrity-related metrics from the at least one RAN node. ### Claim 2 (depends on 1) The method according to claim 1, wherein the information relating to the at least one positioning integrity metric may include an alert limit (AL) of at least one client, application, or device that requires positioning information. ### Claim 3 (depends on 2) The method according to claim 2, wherein the alert limit (AL) comprises a maximum position estimation error that is tolerable by the at least one client, application, or device. ### Claim 4 (depends on 1) The method according to claim 1, further comprising transmitting a request for at least one integrity metric that the at least one RAN node should report. ### Claim 5 (depends on 1) The method according to claim 1, wherein the report comprises measurement and/or positioning estimate reporting. ### Claim 6 (depends on 1) The method according to claim 1, wherein the transmitting comprises transmitting a request for expiry time to the at least one RAN node and the receiving comprises receiving the expiry time from the at least one RAN node, wherein the expiry time indicates the time period during which the reported information can be considered trustable. ### Claim 7 (depends on 1) The method according to claim 1, wherein the transmitting comprises transmitting a request for a certain integrity metric and the receiving comprises receiving a protection level (PL) or an indication of whether there is an integrity risk with regards to a PL. ### Claim 8 (depends on 7) The method according to claim 7, wherein the protection level (PL) comprises an estimate of a maximum possible positioning error. ### Claim 9 (depends on 7) The method according to claim 7, further comprising evaluating if there is an integrity risk based on the received protection level (PL). ### Claim 10 (depends on 1) The method according to claim 1, wherein the receiving comprises receiving a request or recommendation, from the at least one RAN node, to apply or adjust the measurement and/or reporting periodicity. ### Claim 11 (depends on 1) The method according to claim 1, wherein the measurement periodicity comprises a transmission periodicity of at least one reference signal. ### Claim 12 (depends on 1) The method according to claim 1, wherein the receiving comprises receiving a location correction (LC) and/or measurement report from the at least one RAN node. ### Claim 13 (depends on 1) The method according to claim 1, wherein the at least one RAN node comprises at least one of a gNB, transmission-reception point (TRP), or user equipment. ### Claim 14 A method, comprising: receiving information relating to at least one positioning integrity requirement from a location server or location management function (LMF); evaluating the related integrity metrics based on the positioning integrity requirement provided by the location server or LMF and/or based on factors affecting the integrity of the positioning estimate; and providing a report of the one or more evaluated integrity-related metrics to the location server or LMF. ### Claim 15 (depends on 14) The method according to claim 14, wherein the information relating to the at least one positioning integrity metric comprises an alert limit (AL) of at least one client, application, or device that requires positioning information. ### Claim 16 (depends on 15) The method according to claim 15, wherein the alert limit (AL) comprises a maximum position estimation error that is tolerable by the at least one client, application, or device. ### Claim 17 (depends on 14) The method according to claim 14, further comprising receiving a request for at least one integrity metric that should be reported to the location server or LMF. ### Claim 18 (depends on 14) The method according to claim 14, wherein the factors affecting the integrity of the positioning estimate comprises at least one of mobility of the UE, properties of radio propagation, and/or perceived legitimacy of at least one RAN node. ### Claim 19 (depends on 18) The method according to claim 18, wherein the properties of radio propagation comprise presence or strength of line of sight (LoS) path. ### Claim 20 (depends on 14) The method according to claim 14, wherein the report further comprises measurement reporting in the case where the position estimation is performed at the location server or LMF. ### Claim 21 (depends on 14) The method according to claim 14, wherein: the receiving comprises receiving a request for expiry time; the evaluating comprises performing position measurement or estimation and deriving the expiry time; and the transmitting comprises providing the position measurement or estimation and the expiry time to the location server or LMF. ### Claim 22 (depends on 21) The method according to claim 21, wherein the expiry time is derived based on factors including at least one of UE mobility and properties of propagation environment, and/or the alert limit (AL) provided by the location server. ### Claim 23 (depends on 14) The method according to claim 14, wherein: the receiving comprises receiving a request for a certain integrity metric; the evaluating comprises performing position measurement or estimation and deriving the requested integrity metric including a protection level (PL); the transmitting comprises transmitting the PL or an indication of whether there is an integrity risk with regards to a PL to the location server or LMF. ### Claim 24 (depends on 14) The method according to claim 14, wherein: the evaluating comprises evaluating whether the measurement periodicity or reporting periodicity should be updated to ensure that the PL is below the AL; the transmitting comprises transmitting a request or recommendation, to the location server or LMF, to apply or adjust the measurement and/or reporting periodicity. ### Claim 25 (depends on 14) The method according to claim 14, wherein: the receiving comprises receiving a message containing at least the maximum error tolerance; the evaluating comprises using the error tolerance to compute a timing limit (TL) and to perform a check against the reporting periodicity; and when the reporting periodicity is larger than the TL, the evaluating further comprises computing a location correction (LC); and the transmitting comprises transmitting the LC and/or measurement report to the location server or LMF. ### Claim 26 (depends on 25) The method according to claim 25, wherein the location correction (LC) comprises at least one of a set of time-dependent time of arrival (TOA), reference signal time difference (RSTD) values, measured reference signal receive power (RSRP) values, or measured angle values correction terms. ### Claim 27 (depends on 1) An apparatus, comprising: at least one processor; and at least one memory comprising computer program code, the at least one memory and computer program code configured, with the at least one processor, to cause the apparatus at least to perform a method according to claim 1. ### Claim 28 (depends on 1) An apparatus, comprising: means for performing the method according to claim 1. ### Claim 29 (depends on 1) An apparatus, comprising: circuitry configured to perform the method according to claim 1. ### Claim 30 (depends on 1) A computer readable medium comprising program instructions stored thereon for performing at least the method according to claim 1.
