To provide a communication system and a communication equipment suppressing resources of the communication system and communication cost from being uselessly wasted.
Cellular phones 10, 20 perform communication with each other via a base station B. The cellular phone 10 judges whether the cellular phone (e.g., the cellular phone 20) with which the communication is performed is located in its surroundings and when it is judged that the cellular phone is located in its surroundings, regulates the communication with the cellular phone 20. The cellular phone 10 judges whether the cellular phone 20 is located in the surroundings by whether the cellular phone 20 is located in an ID information receivable area R in which ID information about the cellular phone 20 can be received using, for example, an RFID (Radio Frequency-IDentification: radio system authentication) function. The restriction of communication is performed when the cellular phone 20 is called or there is an incoming call from the cellular phone 20.
