A network handover method when a user equipment, UE, is to be handed over from a macro cell to a micro cell performed by a base station gateway, the method comprising: a.) receiving a handover request message or a radio link establishment request message from a source cell radio network controller, RNC, of the macro cell, wherein the handover request message or the radio link establishment request message contains user equipment, UE, capability indication information indicating that the UE has no closed subscriber group, CSG, capability and further contains an UE identifier of the UE; b.) determining whether the handover request message or the radio link establishment request message contains an indication message indicating that an access control has already been completed; c.) if yes in step b.), not initiating an access control process and therefore not performing the following method step d.), but instead directly sending the handover request message or the radio link establishment request message to a target cell base station of the micro cell; d.) if no in step b.), ∘ determining that the UE capability indication information carried in the handover request message or the radio link establishment request message indicates that the UE has no CSG capability, and directly performing the access control to the micro cell according to the UE identifier in the handover request message or the radio link establishment request message (step 404); ∘ if the access control is successful, sending the handover request message or the radio link establishment request message to the target cell base station of the micro cell; ∘ if the access control fails, generating a handover failure message or a radio link establishment failure message and sending the handover failure message or the radio link establishment failure message to the source cell RNC (step 405). a.) receiving a handover request message or a radio link establishment request message from a source cell radio network controller, RNC, of the macro cell, wherein the handover request message or the radio link establishment request message contains user equipment, UE, capability indication information indicating that the UE has no closed subscriber group, CSG, capability and further contains an UE identifier of the UE; b.) determining whether the handover request message or the radio link establishment request message contains an indication message indicating that an access control has already been completed; c.) if yes in step b.), not initiating an access control process and therefore not performing the following method step d.), but instead directly sending the handover request message or the radio link establishment request message to a target cell base station of the micro cell; d.) if no in step b.), ∘ determining that the UE capability indication information carried in the handover request message or the radio link establishment request message indicates that the UE has no CSG capability, and directly performing the access control to the micro cell according to the UE identifier in the handover request message or the radio link establishment request message (step 404); ∘ if the access control is successful, sending the handover request message or the radio link establishment request message to the target cell base station of the micro cell; ∘ if the access control fails, generating a handover failure message or a radio link establishment failure message and sending the handover failure message or the radio link establishment failure message to the source cell RNC (step 405). ∘ determining that the UE capability indication information carried in the handover request message or the radio link establishment request message indicates that the UE has no CSG capability, and directly performing the access control to the micro cell according to the UE identifier in the handover request message or the radio link establishment request message (step 404); ∘ if the access control is successful, sending the handover request message or the radio link establishment request message to the target cell base station of the micro cell; ∘ if the access control fails, generating a handover failure message or a radio link establishment failure message and sending the handover failure message or the radio link establishment failure message to the source cell RNC (step 405).
