1. An information communication processing device, comprising: at least one information processing device having a plurality of function environments each of which includes functions, operating system and middle ware; a switching control unit for switching said function environment; a communication unit which corresponds to each content of communication with the outside to independently receive each said communication content, and to correlate each said communication content received and each said function environment; a communication interpretation unit for interpreting said communication content received by said communication unit to notify said switching control unit of the content; and a resource separation unit which refers to the information of the function environment being currently executed from said switching control unit, and prevents said function environment being currently executed from accessing resources allocated for other function environments on a shared memory such that different function environments may not access a same memory region in the shared resource; where said switching control unit determines a function environment to be switched based on contents of communication with the outside, and sets context of said function environment to be switched at context of a function environment being executed to execute switching to said function environment to be switched, wherein said switching control unit comprising: a switching determination unit for determining a function environment to be switched based on contents of communication with the outside of said information communication processing device; and a context control unit for preserving context of a function environment being executed upon reception of a notification from said switching determination unit to set context of said function environment to be switched, wherein said switching control unit is configured to execute switching of said function environment so that a telephone call may be accepted at a time of switching of said function environment.
