 the first server transfers the received data to the second server selected by the control apparatus, and   the second server selected by the control apparatus transfers, to another server configured to perform processing in one of a network layer and an application layer for data, the data transferred from the first server.   
     
     
         9 . The control apparatus according to  claim 1 , wherein
 the first server receives data from the user apparatus via an L2 tunnel, and   the first server transfers the data, via an L2 tunnel different from the L2 tunnel, to the second server selected by the control apparatus.   
     
     
         10 . The control apparatus according to  claim 1 , wherein
 the gateway includes a plurality of first servers,   the first server receives data from the user apparatus via an L2 tunnel, and   the control apparatus selects the second server serving as a transfer destination of data received from the user apparatus by the first server so as not to overlap identifiers of the L2 tunnels in the second servers.   
     
     
         11 . The control apparatus according to  claim 1 , wherein
 the gateway includes one or more first servers,   the one or more first servers are virtual machines on a cloud,   the control apparatus further performs   an operation of changing performance of the one or more second servers, and   an operation of monitoring a processing status of the one or more second servers, and   the control apparatus performs a change in performance of the one or more first servers and the change in performance of the one or more second servers based on different criteria.   
     
     
         12 . The control apparatus according to  claim 11 , wherein the control apparatus performs the change in the performance of the one or more first servers based on network performance, and the change in the performance of the one or more second servers based on calculation performance. 
     
     
         13 . A control apparatus for a gateway in a mobile communication system, wherein
 the gateway includes a first server configured to receive data from a user apparatus and one or more second servers configured to transfer the data received by the first server to an external network,   the one or more second servers are divided into a plurality of groups, each of the plurality of groups connecting to a respective external network, and   the control apparatus selects, from a group corresponding to identification information of the user apparatus, the second server serving as a transfer destination of the data received from the user apparatus by the first server.
