A communication control device selection method performed by a Serving Gateway, SGW, Selecting Device, which performs the function of a MME, and selecting a serving gateway, SGW, to be connected to a terminal, UE, in a communications system including the terminal that is able to utilize a first communication service and a second communication service other than the first communication service and communication control devices being serving gateways, SGW, that transmit and receive data for utilizing the first communication service or the second communication service, the communication control device selection method comprising: a selection step of specifying one communication service which is utilized by the terminal from among the first communication service and the second communication service, selecting a first communication control device being a first SGW when the specified communication service is the first communication service with reference to information in which the specified communication service and a communication control device being one of the SGWs that transmits and receives the data for utilizing the communication service are correlated with each other, and selecting a second communication control device being a second SGW other than the first communication control device being the first SGW when the specified communication service is the second communication service with reference to the information, wherein: in response to an attachment request sent by the terminal, issuing (S42, S52), by an eNodeB, a mobility management entity, MME, retrieval request message to a SGW selecting device, in response to receiving the MME retrieval request message, issuing (S43, S55), by the SGW selecting device, a DNS query request including a service type and a user equipment, UE, usage type of the terminal to a DNS, in response to receiving the DNS query request, acquiring, by the DNS, an address of the SGW corresponding to the service type of the terminal and acquiring an address of the MME corresponding to the service type or the UE usage type, and transmitting (S44, S56) the addresses of the selected MME and the selected SGW to the SGW selecting device in a DNS query response, and a transmitting step (S45, S57) of transmitting a MME Selection Response message, by the SGW selecting device, indicating the address of the selected MME and the address of the selected SGW to the eNodeB. a selection step of specifying one communication service which is utilized by the terminal from among the first communication service and the second communication service, selecting a first communication control device being a first SGW when the specified communication service is the first communication service with reference to information in which the specified communication service and a communication control device being one of the SGWs that transmits and receives the data for utilizing the communication service are correlated with each other, and selecting a second communication control device being a second SGW other than the first communication control device being the first SGW when the specified communication service is the second communication service with reference to the information, wherein: in response to an attachment request sent by the terminal, issuing (S42, S52), by an eNodeB, a mobility management entity, MME, retrieval request message to a SGW selecting device, in response to receiving the MME retrieval request message, issuing (S43, S55), by the SGW selecting device, a DNS query request including a service type and a user equipment, UE, usage type of the terminal to a DNS, in response to receiving the DNS query request, acquiring, by the DNS, an address of the SGW corresponding to the service type of the terminal and acquiring an address of the MME corresponding to the service type or the UE usage type, and transmitting (S44, S56) the addresses of the selected MME and the selected SGW to the SGW selecting device in a DNS query response, and in response to an attachment request sent by the terminal, issuing (S42, S52), by an eNodeB, a mobility management entity, MME, retrieval request message to a SGW selecting device, in response to receiving the MME retrieval request message, issuing (S43, S55), by the SGW selecting device, a DNS query request including a service type and a user equipment, UE, usage type of the terminal to a DNS, in response to receiving the DNS query request, acquiring, by the DNS, an address of the SGW corresponding to the service type of the terminal and acquiring an address of the MME corresponding to the service type or the UE usage type, and transmitting (S44, S56) the addresses of the selected MME and the selected SGW to the SGW selecting device in a DNS query response, and a transmitting step (S45, S57) of transmitting a MME Selection Response message, by the SGW selecting device, indicating the address of the selected MME and the address of the selected SGW to the eNodeB.
