Abstract:
1. A communication control method comprising: recording identification information of a first terminal apparatus at a relay apparatus acting as an access point of wireless LAN, wherein the identification information to be recorded is included in a request packet for establishing a streaming communication between the first terminal apparatus and a second terminal apparatus among packets to be relayed by the relay apparatus; determining whether a number of terminal apparatuses whose identification information is recorded at the relay apparatus exceeds a preset upper value; disconnecting a connection between the relay apparatus and the first terminal apparatus if it is determined that the number of terminal apparatuses whose identification information is recorded at the relay apparatus exceeds the preset upper limit value; beginning a timer process at the relay apparatus for measuring a predetermined period of time when recording the identification information of the first terminal apparatus; determining whether the identification information of the first terminal apparatus is previously recorded at the relay apparatus; resetting the predetermined period of time if it is determined that the identification information of the first terminal apparatus is previously recorded at the relay apparatus; and deleting the identification information of the first terminal apparatus from identification information recorded at the relay apparatus if the predetermined period of time expires, wherein when the relay apparatus records the identification information of the first terminal apparatus, the relay apparatus relates a preset weight value to the identification information to be recorded according to the number of packets per unit time and the data length of a streaming communication carried out by the first terminal apparatus, and wherein the relay apparatus periodically determines whether a number of packets per unit time of a streaming communication carried out at the time exceeds a preset upper limit value, and when the number of packets per unit time exceeds the upper limit value, the relay apparatus disconnects a connection between the relay apparatus and a terminal apparatus.
