Abstract (en)
[origin: WO2022048785A1] The present disclosure relates to a method performed by a MME (113) for handling mobility of a UE (101). The MME (113) detects a move of the UE (101) from a 5GS (103) to an EPS (105). When the move to the EPS (105) is detected, the MME (113) obtains UE related data from an AMF (110). The UE related data does not comprise a parameter. Since the data does not comprise the parameter, the MME (113) indicates that a PDN connection of the UE (101) in the EPS (105) as originating from the 5GS (103). When the move to the EPS (105) is completed, the MME (113) detects a move of the UE (101) from the EPS (105) to a 2G or a 3G communication network (108). When the move to the 2G or the 3G communication network (108) has been detected, the MME (113) removes the PDN connection.
