Currently, frequency vibrations are used to sig- nal an incoming call to the user. Users may require, or desire, more information about the incoming call in order to decide how they wish to proceed. A method for a radio user to distinguish the priority, the type of incoming call, and/or the sender of a call by the frequency of vibrations used to alert the mobile user of the call would provide a greater range of information to the user.

be able to quickly distinguish the identity of the caller, without having to remove the radio fmm his belt.
The use of variable frequency of the vibration to indicate call priority may be used in combination, or independently from the pulse train pattern to indi- cate the caller identity.
Furthermore, the user can select between differ- ent vibration modes of output. For example, the user may choose to use intensity of vibration as opposed to the frequency of the vibration to indicate priority, or use frequency of vibration to indicate something other than priority, as he chooses.
Alternatively, a user may be alerted of an incoming call by means of a flashing light on the message display. In this case, the frequency of flashing may indicate the priority of the call. A par- ticular flashing pattern would be used to indicate the identity of the caller.
The user may choose to change these associa- tions, or make further associations he deems impor- tant. For example, light intensity, or color of light could be substituted for either frequency of flashing pattern as described above. Additionally, the user could make new associations with other information chosen by the user. For example, a user could fur- ther differentiate a group call on Talk Group A by a red flashing light versus a green light for Talk Group B
This method of information discrimination via frequency manipulation could be incorporated into mobile radios, mobile phones, pagers, and other communication devices which would allow for dif- ferent types of information to be transmitted to the user via frequency manipulatio...
