A method in a mobility management node of a wireless communications network, the method comprising: receiving (18-1, 19-1, 20-1), by the mobility management node, a first Non Access Stratum "NAS" message from a User Equipment "UE" that has, with a first network element, at least one of a Local IP Access "LIPA" packet data network "PDN" connection and a selected Internet Protocol traffic offload "SIPTO" PDN connection, an identifying characteristic associated with the at least one of the LIPA PDN connection and the SIPTO PDN connection being stored at the mobility management node, wherein the first network element is different from the mobility management node; detecting, by the mobility management node, that the UE (1802, 1902, 2002) is connected to a second network element that is different from the first network element and different from the mobility management node, wherein the detecting comprises determining that the first NAS message is received with an identifying characteristic different from the identifying characteristic associated with the at least one of the LIPA PDN connection and the SIPTO PDN connection; and in response to determining that the first NAS message is received with an identifying characteristic different from the identifying characteristic associated with the at least one of the LIPA PDN connection and the SIPTO PDN connection, deactivating (18-2, 19-2, 20-2), by the mobility management node, at least one of the LIPA PDN connection and the SIPTO PDN connection; and in response to a condition that no PDN connection remains as a result of the deactivating, sending, by the mobility management node, a second NAS message causing the UE to perform a new attach procedure, wherein the second NAS message includes an indication to force the UE to perform the new attach procedure, and a cause code with a value that represents at least one of "Implicitly Detached" and "No EPS Bearer Context Activated". receiving (18-1, 19-1, 20-1), by the mobility management node, a first Non Access Stratum "NAS" message from a User Equipment "UE" that has, with a first network element, at least one of a Local IP Access "LIPA" packet data network "PDN" connection and a selected Internet Protocol traffic offload "SIPTO" PDN connection, an identifying characteristic associated with the at least one of the LIPA PDN connection and the SIPTO PDN connection being stored at the mobility management node, wherein the first network element is different from the mobility management node; detecting, by the mobility management node, that the UE (1802, 1902, 2002) is connected to a second network element that is different from the first network element and different from the mobility management node, wherein the detecting comprises determining that the first NAS message is received with an identifying characteristic different from the identifying characteristic associated with the at least one of the LIPA PDN connection and the SIPTO PDN connection; and in response to determining that the first NAS message is received with an identifying characteristic different from the identifying characteristic associated with the at least one of the LIPA PDN connection and the SIPTO PDN connection, deactivating (18-2, 19-2, 20-2), by the mobility management node, at least one of the LIPA PDN connection and the SIPTO PDN connection; and in response to a condition that no PDN connection remains as a result of the deactivating, sending, by the mobility management node, a second NAS message causing the UE to perform a new attach procedure, wherein the second NAS message includes an indication to force the UE to perform the new attach procedure, and a cause code with a value that represents at least one of "Implicitly Detached" and "No EPS Bearer Context Activated".
