`BACKGROUND OF THE INVENTION
`
`1. Field of Invention
`This invention relates generally to telecommunication, and
`more particularly to methods, systems, apparatuses, and com
`puter readable media for initiating or enabling a call with a
`mobile telephone to a callee.
`2. Description of Related Art
`Mobile telephone service providers often charge signifi
`cant fees for long distance telephone calls, particularly when
`the mobile telephone is roaming in another mobile telephone
`service provider's network.
`One known technique for avoiding the long distance
`charges of mobile telephone service providers is to use a
`“calling card'. A “calling card may permit the user of the
`mobile telephone to place a call to a local telephone number
`or to a less-expensive telephone number (such as a toll-free
`number, for example) instead of placing the call directly to the
`callee. The user may thus avoid the long distance charges of
`the mobile telephone service provider, which may be higher
`than the charges for using the “calling card. However, this
`technique can be cumbersome and undesirable, because it
`may require the user of the mobile telephone to follow a
`number of complicated or cumbersome steps in order to ini
`tiate a call to the callee, for example.

`
`SUMMARY OF THE INVENTION
`
`In accordance with one aspect of the invention there is
`provided a method of initiating a call to a callee using a
`mobile telephone. The method involves receiving, from a user
`of the mobile telephone, a callee identifier associated with the
`callee; transmitting an access code request message to an
`access server, the access code request message including the
`callee identifier; receiving an access code reply message from
`the access server in response to the access code request mes
`sage, the access code reply message including an access code
`different from the callee identifier and associated with the
`callee identifier; and initiating a call with the mobile tele
`phone using the access code to identify the callee.
`Transmitting may involve transmitting the access code
`request message to the access server on a non-voice network.
