When a page message containing a caller ID is received from a caller, a call back message containing one of prepared response messages is transmitted to a call number associated with the caller ID. For this, the system displays the prepared response messages and prompts the user to select one of them. A call back message is compiled from a call back number associated with a caller ID contained in the page message and the selected response message. The call back message is transmitted to the call back number. The compilation of call back message is performed such that the format of call back message is adapted to the type of the caller's communication device associated with the caller ID.

Mobile paging telephone with an automatic call back function

A system with a mobile phone capable of receiving a paging message. A method and apparatus automatically transmits a callback message to a callback number associated with the caller in response to a page message. The user of the system prepares a data structure in which a caller ID of each of the prospective callers in associated with information on the caller as well as the caller's communication device. In response to the reception of a page message, the user can display a response message used for calling back the caller when the user is busy. When the user selects the response message, the call back message is compiled using a call back number associated with a caller ID contained in the page message. The callback message can then be sent to the caller.

A pair of bands are each secured at one end to one side of a case wherein a radio receiver is housed, and a monopole antenna having a length of 0.005.lambda. has one end connected to the feeding point of the radio receiver and its other end exposed to the outside of the case to form a contact portion for contact with the human body. A first helical antenna is supported to the one of the bands lengthwise thereof and is connected at one end to the feeding point. A second helical antenna is supported to the other band lengthwise thereof and is connected at one end to the common potential point of the radio receiver. The first and second helical antennas resonate, as one antenna, with the wavelength .lambda. used by the radio receiver, and their pitch P and helix area A are selected so that P&lt;500A/.lambda. and P&gt;150A/.lambda.. In an alternative embodiment first and second zigzag antennas are supported on said pair of bands respectively, and similarly connected to said feeding and common potential points instead of said helical antennas.
