Abstract: A non-transitory computer-readable recording medium having stored therein a communication control program for causing a computer to execute a process includes: receiving, from each of a plurality of base stations, communication result between the respective base stations and a communication terminal; storing, when the received communication result indicates that transmission of a message from a first base station to a specific communication terminal is failed, the message in a storage in association with identification information on the specific communication terminal; and referring, when the received communication results indicates that communication is established between a second base station and the specific communication terminal, to the storage, transmitting the message stored in association with the identification information on the specific communication terminal to the second base station, and requesting the second base station to transmit the message to the specific communication terminal.

Abstract: A non-transitory computer-readable recording medium having stored therein a base station determination program for causing a computer to execute a process includes: acquiring position information on a communication terminal; assigning, based on position information on each of a plurality of base stations stored in advance in a storage and the acquired position information on the communication terminal, one or more base stations other than a base station that includes a point at which a radio wave characteristic based on longitude information changes in a time slot during which communication is to be performed, and which is provided between a position of the base station and a position of the communication terminal, as one or more base station candidates from among the plurality of base stations; and determining a base station that is to communicate with the communication terminal from among the one or more base station candidates.

Abstract: A non-transitory computer-readable recording medium having stored therein a message information acquisition program for causing a computer to execute a process includes: receiving, from each of a plurality of base stations that receive a first message which is transmitted by a communication terminal, a second message in which information indicated by the first message is divided into parts each in an error checkable format; performing an error check for each of the parts; extracting, in each of a plurality of second messages indicating the same information, a divided piece of information from one or more parts without an error of the parts; joining the divided pieces of information; and acquiring the information indicated by the first message.
