A method performed by a user plane, UP, apparatus, wherein the UP apparatus is represented by a Serving Gateway-User plane, SGW-U, a Packet Data Network Gateway-User plane, PGW-U, or a Traffic Detection Function-User plane, TDF-U, the method comprising: determining whether a redirect message should be sent to a user equipment, UE, that has transmitted a first request message intended for a first server, wherein the determining comprises: i) receiving a response message transmitted by the first server and determining, based on the response message, whether a redirect message should be sent to the UE or ii) detecting a timeout with respect to the first server; determining whether the redirect message should be sent to the UE comprises receiving the response message transmitted by the first server and determining whether the response message includes a redirection parameter that matches any redirection parameter included in a set of one or more locally configured redirection parameters, wherein the redirection parameter is the response code or a specific timeout value; if the response message includes the redirection parameter that matches any redirection parameter included in the set of one or more locally configured redirection parameters, then it is determined that the redirection should be sent to the UE; as a result of determining that redirect message should be sent to the UE, sending (405, 508, 704) to the UE the redirect message, wherein the redirect message is configured to cause the UE to send a second message to a second server; and the method further comprising receiving a redirection rule transmitted by a control plane, CP, wherein receiving the redirection rule comprises receiving a message comprising the redirection rule, wherein the redirection rule indicates at least one redirection parameter to be locally configured in the UP apparatus, wherein the message is: an Sx Session Establishment Request message, or an Sx Session Establishment Response message, or an Sx Session Modification Request message, or an Sx Session Modification Response message. determining whether a redirect message should be sent to a user equipment, UE, that has transmitted a first request message intended for a first server, wherein the determining comprises: i) receiving a response message transmitted by the first server and determining, based on the response message, whether a redirect message should be sent to the UE or ii) detecting a timeout with respect to the first server; determining whether the redirect message should be sent to the UE comprises receiving the response message transmitted by the first server and determining whether the response message includes a redirection parameter that matches any redirection parameter included in a set of one or more locally configured redirection parameters, wherein the redirection parameter is the response code or a specific timeout value; if the response message includes the redirection parameter that matches any redirection parameter included in the set of one or more locally configured redirection parameters, then it is determined that the redirection should be sent to the UE; as a result of determining that redirect message should be sent to the UE, sending (405, 508, 704) to the UE the redirect message, wherein the redirect message is configured to cause the UE to send a second message to a second server; and the method further comprising receiving a redirection rule transmitted by a control plane, CP, wherein receiving the redirection rule comprises receiving a message comprising the redirection rule, wherein the redirection rule indicates at least one redirection parameter to be locally configured in the UP apparatus, wherein the message is: an Sx Session Establishment Request message, or an Sx Session Establishment Response message, or an Sx Session Modification Request message, or an Sx Session Modification Response message. an Sx Session Establishment Request message, or an Sx Session Establishment Response message, or an Sx Session Modification Request message, or an Sx Session Modification Response message.
