Portable radio apparatus having function for compressing and transmitting data

A portable radio apparatus comprising:

• a memory for storing, while said portable radio apparatus is located outside a communication service area, data to be transmitted and destination information indicating the destination to which said data is to be transmitted when said portable radio apparatus is located within a communication service area;
• data compression section for compressing said data to be transmitted;
• data decompression section for decompressing said data compressed by said data compression section;
• determination section for determining whether or not said destination to which said data is to be sent has said data decompression section;
• and
• transmission section for automatically transmitting said data to be transmitted and stored in said memory to said destination based on the result of said determination made by said determination section when said portable radio apparatus is located within said communication service area.

A portable radio apparatus comprising:

• a memory for storing data to be transmitted and information concerning the destination to which such data is to be transmitted once said radio apparatus is located inside a communication service area;
• and
• transmission section for automatically transmitting a plurality of said transmitted data stored in said memory in a batch to a common destination based on said destination information which said radio apparatus is located within said communication service area;
• determination section which determines whether or not said destination information is already stored in said memory;
• and
• adding section for adding only said data to be transmitted to said destination information stored in said memory when said destination information is determined by said determination section to already be stored in said memory.

A portable radio apparatus comprising:

• a memory for storing data to be transmitted and destination information indicating the destination to which said data should be transmitted when said radio apparatus is located in a communication service area;
• a transmission operation management section for determining whether or not said destination information is already stored in said memory, and for adding only said data to be transmitted to said destination information stored in said memory when said destination information is determined to already be stored in said memory;
• a compression section for compressing said data to be transmitted;
• a decompression section for decompressing said data to be transmitted which was compressed by said compression section;
• and
• a transmission section for automatically transmitting a plurality of said data to be transmitted which are stored in said memory in a batch based on said destination information when said radio apparatus is located within said communication service area.

A method for operating a portable radio apparatus, said method comprising the steps of:

• determining whether or not destination information and data to be transmitted are inputted;
• storing said destination information and said data to be transmitted;
• determining whether or not an operation is performed for transmitting said data;
• determining whether or not said portable radio apparatus is located within a communication service area;
• detecting whether or not said destination information for said data is already stored when said portable radio apparatus is determined not be located within the communication service area;
• adding only said data to said destination information already stored when said destination information is already stored;
• and
• transmitting said data to a location indicated by said destination information in a batch when said portable radio apparatus is determined to be located within the communication service area.

A method for operating a portable radio apparatus comprising the steps of:

• determining whether or not data to be transmitted is inputted;
• determining whether or not an operation is performed for transmitting said data;
• compressing said data;
• determining whether or not said portable radio apparatus is located within a communication service area;
• determining whether or not a radio apparatus to which said data is to be transmitted has data decompression means capable of decompressing said compressed data;
• and
• transmitting said compressed data when said radio apparatus to which said data is to be transmitted has said data decompression means.

A portable radio apparatus comprising:

• memory for storing data to be transmitted and destination information to which said data is to be transmitted when said portable radio apparatus is located within a communication service area;
• a determination section for determining whether or not said destination information is already stored in said memory;
• an adding section for adding only said data to said destination information stored in said memory when said destination information is determined by said determination section to already be stored in said memory;
• and
• a transmission section for transmitting a plurality of said data store in said memory in a batch based on said destination information when said portable radio apparatus is located within said communication service area.
