A method for processing a quality of service, QoS, parameter in a subscription service combination scenario, comprising: determining, multiple subscribed access point names, APNs, according to an alias APN which is obtained by a mobility management network element, MMNE, according to an APN carried in an access request of a user equipment, UE, and a mapping relation between the alias APN and the APN carried in the access request, wherein the alias APN is an APN to which the multiple subscribed APNs are mapped and the APN carried in the access request is one of the multiple subscribed APNs; and determining, a QoS parameter of the alias APN according to QoS parameters of the multiple subscribed APNs; wherein the determining, the QoS parameter of the alias APN according to the QoS parameters of the multiple subscribed APNs comprises: determining, the QoS parameter of the alias APN is an accumulated value of a QoS parameter of a subscribed APN being activated currently of the multiple subscribed APNs and a QoS parameter of an already activated subscribed APN of the multiple subscribed APNs; or determining, the QoS parameter of the alias APN is a maximum value of a QoS parameter of a subscribed APN being activated currently of the multiple subscribed APNs and a QoS parameter of an already activated subscribed APN of the multiple subscribed APNs; or determining, the QoS parameter of the alias APN is an accumulated value of QoS parameters of the multiple subscribed APNs; or determining, the QoS parameter of the alias APN is a maximum value of OoS parameters of the multiple subscribed APNs. determining, multiple subscribed access point names, APNs, according to an alias APN which is obtained by a mobility management network element, MMNE, according to an APN carried in an access request of a user equipment, UE, and a mapping relation between the alias APN and the APN carried in the access request, wherein the alias APN is an APN to which the multiple subscribed APNs are mapped and the APN carried in the access request is one of the multiple subscribed APNs; and determining, a QoS parameter of the alias APN according to QoS parameters of the multiple subscribed APNs; wherein the determining, the QoS parameter of the alias APN according to the QoS parameters of the multiple subscribed APNs comprises: determining, the QoS parameter of the alias APN is an accumulated value of a QoS parameter of a subscribed APN being activated currently of the multiple subscribed APNs and a QoS parameter of an already activated subscribed APN of the multiple subscribed APNs; or determining, the QoS parameter of the alias APN is a maximum value of a QoS parameter of a subscribed APN being activated currently of the multiple subscribed APNs and a QoS parameter of an already activated subscribed APN of the multiple subscribed APNs; or determining, the QoS parameter of the alias APN is an accumulated value of QoS parameters of the multiple subscribed APNs; or determining, the QoS parameter of the alias APN is a maximum value of OoS parameters of the multiple subscribed APNs. determining, the QoS parameter of the alias APN is an accumulated value of a QoS parameter of a subscribed APN being activated currently of the multiple subscribed APNs and a QoS parameter of an already activated subscribed APN of the multiple subscribed APNs; or determining, the QoS parameter of the alias APN is a maximum value of a QoS parameter of a subscribed APN being activated currently of the multiple subscribed APNs and a QoS parameter of an already activated subscribed APN of the multiple subscribed APNs; or determining, the QoS parameter of the alias APN is an accumulated value of QoS parameters of the multiple subscribed APNs; or determining, the QoS parameter of the alias APN is a maximum value of OoS parameters of the multiple subscribed APNs.
