Description

Multi-channel access relay method and apparatus for supporting wireless data communication service and short message service

The present invention relates to a multi-channel access relay apparatus for supporting a wireless data communication service and a short message service.

Digital wireless communication network, which can be highlighted as a dominant communication network in the future, has a cell structure and provides voice communication and data communication, and dual data communication is a wireless data communication service and a short message service. Are divided into two forms. Wireless data communication services typically transmit and receive data over traffic channels, and SMS transmits and receives data using a paging channel (also called an access channel).

SMS can receive, view, produce, and send messages only through a wireless communication terminal. In a wireless data communication service, a wireless communication terminal usually serves only as a communication modem for transmitting and receiving data, and for reading, processing, storing, and producing data. This is performed by an information processor such as a computer connected to the wireless communication terminal. Recently, wireless communication terminals have also been commercialized to enable SMS communication even through an external information processor connected to the wireless communication terminal during SMS communication.

1 is a view for explaining a wireless data communication service and SMS using a wireless communication and wired communication in the prior art.

As shown in FIG. 1, the communication counterparts of the wired communication network (hereinafter, referred to as 'wired communication users') 91, 92 and 93 are the Internet network 5, the PSDN network 6, or the PSTN network 7. It is connected to the wireless communication network (2) through the user of the wireless communication network side (hereinafter referred to as 'wireless communication') (1) and wired communication (91, 92, 93) of the wireless data communication service or SMS Select one to perform data communication. The wireless data communication service between the wireless communication device 1 and the wired communication devices 91, 92, and 93 is performed through the wireless data communication service relay device 4, and the SMS communication is performed by the Short Message Service Center (SMS) (3). It is done through.

That is, when all the communication parties are connected to the wireless communication network, a symmetrical configuration diagram is established around the Internet network 5, the PSDN network 6, or the PSTN network 7.

The wireless communicator is capable of SMS communication using only the wireless communication terminal, and also uses a wireless communication terminal connected to an external information processor, or a combination of the wireless communication terminal and the information processor. When the information processor is connected, wireless data communication service or SMS communication may be selectively or simultaneously used.

In this way, a wireless communication network can be used to communicate using both a wireless data communication service and an SMS, which is referred to as multi-channel communication.

Communication service using a wireless communication network has the advantage that can communicate regardless of the place. However, in the case of SMS communication, although it is suitable for sending and receiving simple messages, it is impossible to send and receive a large amount of data such as a file, whereas in the case of a wireless data communication service, it is suitable for sending and receiving a large amount of data, but the charges are charged. There was an expensive issue.

SUMMARY OF THE INVENTION An object of the present invention is to solve the problems of the prior art as described above, which reduces the cost of using a wireless communication network on the user side of the wireless communication network and allows more users to communicate with the same communication capacity on the wireless network service provider side. The present invention provides a method and an apparatus capable of increasing communication efficiency.
