In one embodiment, a wireless communication device receives an authentication reject message from a wireless communication node as part of a procedure. In response to receiving the authentication reject message, the wireless communication device deletes a network list to which the wireless communication node belongs. The network list may include a Public Land Mobile Network (PLMN) list or an equivalent Standalone Non-Public Network (SNPN) list. Additionally, the wireless communication device may reset various counters, including a registration attempt counter, an attach attempt counter, a service attempt counter, and a Tracking Area Update (TAU) attempt counter. The procedure may be a registration procedure, an attach procedure, or a Tracking Area Update (TAU) procedure. The system and method may also be implemented in an apparatus comprising a transceiver and a processor configured to perform the described operations. ## Claims ### Claim 1 A wireless communication method, comprising: receiving, by a wireless communication device from a wireless communication node, a authentication reject message initiated as a part of a procedure; and in response to receiving the authentication reject message, deleting, by the wireless communication device, a network list to which the wireless communication node belongs. ### Claim 2 (depends on 1) The wireless communication method of claim 1, wherein the procedure is a registration procedure, an attach procedure, or a Tracking Are Update (TAU) procedure. ### Claim 3 (depends on 1) The wireless communication method of claim 1, wherein the network list includes a Public Land Mobile Network (PLMN) list or an equivalent Standalone Non-Public Network (SNPN) list. ### Claim 4 (depends on 1) The wireless communication method of claim 1, in response to receiving the authentication reject message, further comprising: resetting, by the wireless communication device, a registration attempt counter. ### Claim 5 (depends on 1) The wireless communication method of claim 1, in response to receiving the authentication reject message, further comprising: resetting, by the wireless communication device, an attach attempt counter. ### Claim 6 (depends on 1) The wireless communication method of claim 1, in response to receiving the authentication reject message, further comprising: resetting, by the wireless communication device, a service attempt counter. ### Claim 7 (depends on 1) The wireless communication method of claim 1, in response to receiving the authentication reject message, further comprising: resetting, by the wireless communication device, a Tracking Area Update (TAU) attempt counter. ### Claim 8 An apparatus, comprising: a transceiver configured to wirelessly communicate with a network; and a processor coupled to the transceiver and configured to operations comprising: receiving, from the network, an authentication reject message initiated as part of a procedure; and in response to receiving the authentication reject message, deleting a network list to which the network belongs. ### Claim 9 (depends on 8) The apparatus of claim 8, wherein the procedure is a registration procedure, an attach procedure, or a Tracking Are Update (TAU) procedure. ### Claim 10 (depends on 8) The apparatus of claim 8, wherein the network list includes a Public Land Mobile Network (PLMN) list or an equivalent Standalone Non-Public Network (SNPN) list. ### Claim 11 (depends on 8) The apparatus of claim 8, wherein the operations further comprise: resetting a registration attempt counter. ### Claim 12 (depends on 8) The apparatus of claim 8, wherein the operations further comprise: resetting an attach attempt counter. ### Claim 13 (depends on 8) The apparatus of claim 8, wherein the operations further comprise: resetting a service attempt counter. ### Claim 14 (depends on 8) The apparatus of claim 8, wherein the operations further comprise: resetting a Tracking Area Update (TAU) attempt counter. ### Claim 15 A wireless communication method, comprising: transmitting, by a wireless communication node to a wireless communication device, an authentication reject message initiated as part of a procedure; wherein a network list to which the wireless communication node belongs is configured to be deleted by the wireless communication device, in response to the wireless communication device receiving the authentication reject message. ### Claim 16 (depends on 15) The wireless communication method of claim 15, wherein the procedure is a registration procedure, an attach procedure, or a Tracking Are Update (TAU) procedure. ### Claim 17 (depends on 15) The wireless communication method of claim 15, wherein the network list includes a Public Land Mobile Network (PLMN) list or an equivalent Standalone Non-Public Network (SNPN) list. ### Claim 18 (depends on 15) The wireless communication method of claim 15, wherein, in response to receiving the authentication reject message, the wireless communication device is configured to reset at least one of: a registration attempt counter, an attach attempt counter, a service attempt counter, or a Tracking Area Update (TAU) attempt counter. ### Claim 19 An apparatus, comprising: a transceiver configured to wirelessly communicate with a network; and a processor coupled to the transceiver and configured to operations comprising: transmitting, to a wireless communication device, an authentication reject message initiated as part of a procedure, wherein a network list to which the apparatus belongs is configured to be deleted by the wireless communication device, in response to the wireless communication device receiving the authentication reject message. ### Claim 20 (depends on 19) The apparatus of claim 19, wherein the network list includes a Public Land Mobile Network (PLMN) or an equivalent Standalone Non-Public Network (SNPN) list. ### Claim 21 (depends on 19) The apparatus of claim 19, wherein the procedure is a registration procedure, an attach procedure, or a Tracking Are Update (TAU) procedure.
