Abstract

A recyclable cellular telephone is disclosed having an inner rigid cellular electronics supporting frame member surrounded by a replaceable outer cover. The telephone is acquired having a limited period of use. The electronics of the telephone operate to disable the telephone following expiration of the period of use. Following expiration of the period of use, the telephone is returned for refurbishment where the outer cover is stripped and replaced and the electronics tested before being recycled with a new period of use for an another acquisition. The cellular network supporting telephone operation also monitors the period of use, disabling telephone access to the network following expiration. Directory numbers are selectively assigned to the recyclable telephones from a pool of available numbers, with assigned numbers returned to the pool after expiration of a predetermined period or telephone deactivation for re-use by another recyclable telephone. The recyclable telephones are activated and deactivated in a number of ways, including through the use of a separate activation and deactivation station which communicates with the telephones over a radio frequency communications link.

Claims

1. A telecommunications instrument, comprising:

means for engaging in wireless communications;

a memory storing information concerning a predetermined available period of use for the telecommunications instrument; and

a processing unit connected to the memory and the means for engaging, the processing unit monitoring telecommunications instrument use in view of the stored information on the predetermined available period of use and controlling operation of the telecommunications instrument to cause said telecommunications instrument to operate in a first mode during said predetermined available period of use, said first mode supporting both outgoing calls and incoming calls, and causing said telecommunications instrument to operate in a second mode when said predetermined available period of use expires, said second mode supporting only outgoing calls.

2. The telecommunications instrument as in claim 1 wherein the predetermined period of use comprises a maximum amount of communications talk time, and the processing unit monitors talk time expended during engaging in wireless communications.

3. The telecommunications instrument as in claim 1 wherein the predetermined period of use comprises a maximum number of calling events, and the processing unit monitors the occurrence of calling events during telecommunications instrument operation.
