A server access method and a network system

The invention is applicable to the field of communication technology, and provides a server access method and a network system. The server access method comprises the following steps: an external network server receives a user request sent by a mobile end, and forms a user request queue; Wherein the external network server is connected with a plurality of access servers through a load balancing device; The load balancing device polls and distributes the user request in the user request queue to the access server with the lowest load; The access server allocates the received user request basedon the load balancing algorithm to the application server in a polling manner, and the application server receives and feeds back the user request, wherein each of the access servers is connected to aplurality of application servers. The invention improves the stability of the network and the load capacity of the server through multi-server operation. 本发明适用于通信技术领域，提供了种服务器接入方法及网络系统，其中，服务器接入方法包括：外网服务器接收到移动端发送的用户请求，形成用户请求队列；
