The invention provides a network connection method and an apparatus thereof. The network connection method comprises the following steps that a network side device receives a network connection request sent by user equipment to an evolution packet data gateway; bandwidth resources are reserved at the network side device and the evolution packet data gateway; and the network side device sends the connection request to the evolution packet data gateway; and whether to establish network connection between the user equipment and the evolution packet data gateway is determined based on whether the bandwidth resources are successfully reserved at the network-side device and the evolution packet data gateway. By using the network connection method, under the condition of high speed downloading of a user, VoWiFi service quality can be guaranteed.
