The AMF provides, to a user equipment (UE), information about permissible sensors supporting a sensor-based network access from among sensors possessed by the UE. The performance management module stores the permissible sensor information. Upon receiving a list of the sensors possessed by the UE from the UE, the AMF extracts, from the performance management module, the permissible sensor information including a list of the permissible sensors and a permissible condition for permitting network access through the permissible sensors. ## Claims ### Claim 1 An apparatus for controlling network access, comprising: an access and mobility management function module (AMF) providing, to a user equipment (UE), information about permissible sensors supporting a sensor-based network access from among sensors possessed by the UE; and a performance management module storing the permissible sensor information, wherein the AMF is configured to: upon receiving a list of the sensors possessed by the UE from the UE, extract, from the performance management module, the permissible sensor information including a list of the permissible sensors and a permissible condition for permitting network access through the permissible sensors. ### Claim 2 (depends on 1) The apparatus of claim 1, wherein the AMF is further configured to: upon receiving a sensor value and identification information of at least one sensor through a request message from the UE, determine whether the sensor value and the identification information of the sensor satisfy the permissible condition, and permit an access of the UE when determining that the permissible condition is satisfied. ### Claim 3 (depends on 1) The apparatus of claim 1, wherein the permissible condition includes a sensor value in which the network access through permissible sensor is permitted. ### Claim 4 (depends on 1) The apparatus of claim 1, wherein the permissible condition includes a measurement scheme in which the permissible sensor measures a sensor value. ### Claim 5 (depends on 1) The apparatus of claim 1, wherein the AMF transmits, to the UE, an indicator that enables the UE to operate in an idle mode in accordance with the permissible sensor information. ### Claim 6 (depends on 1) The apparatus of claim 1, further comprising: an application function module (AF) that performs provisioning of the permissible sensor information to the performance management module directly or through a network exposure function module (NEF). ### Claim 7 A method for controlling network access, comprising: at an access and mobility management function module (AMF), receiving a list of sensors possessed by a user equipment (UE) from the UE; at the AMF, extracting, from a performance management module, permissible sensor information that includes a list of permissible sensors supporting a sensor-based network access from among the sensors possessed by the UE and a permissible condition for permitting network access through the permissible sensors; and at the AMF, transmitting the permissible sensor information to the UE so that the sensors possessed by the UE are set in accordance with the permissible sensor information. ### Claim 8 (depends on 7) The method of claim 7, further comprising: after transmitting the permissible sensor information to the UE, receiving a sensor value and identification information of at least one sensor through a request message from the UE; determining whether the sensor value and the identification information of the sensor satisfy the permissible condition; and at the AMF, permitting an access of the UE when determining that the permissible condition is satisfied. ### Claim 9 (depends on 7) The method of claim 7, wherein the permissible condition includes a sensor value in which the network access through permissible sensor is permitted. ### Claim 10 (depends on 7) The method of claim 7, wherein the permissible condition includes a measurement scheme in which the permissible sensor measures a sensor value. ### Claim 11 (depends on 7) The method of claim 7, wherein transmitting the permissible sensor information to the UE includes transmitting an indicator that enables the UE to operate in an idle mode in accordance with the permissible sensor information. ### Claim 12 (depends on 7) The method of claim 7, further comprising: before receiving the list of sensors possessed by the UE, at an application function module (AF), performing provisioning of the permissible sensor information to the performance management module directly or through a network exposure function module (NEF).
