Electronic apparatus and wireless network system
First Claim
1. An electronic apparatus connectable to a plurality of wireless networks, said electronic apparatus comprising:
- a radio section for directly communicating with a first electronic apparatus which belongs to a first wireless network or for communicating with said first electronic apparatus via a second electronic apparatus which belongs to a second wireless network, said second electronic apparatus performing data relay between said first wireless network and said second wireless network;
an error detector for detecting an error of first data received directly from said first electronic apparatus or for detecting an error of second data received from said first electronic apparatus via said second electronic apparatus; and
a selector for selecting data from said first data or said second data depending on a result detected by said error detector, wherein;
when an error rate detected by said error detector has reached or exceeded a predetermined value while communicating with an electronic apparatus which belongs to one of said first wireless network and said second wireless network, said radio section starts communications over a path which belongs to the other wireless network.

Abstract
Electronic apparatus such as a cordless phone, the electronic apparatus includes detection means for detecting the error of received data and at least two speech buffers as speech buffers for temporarily storing the received voice data. In case the electronic apparatus is in a position where it can communicate with a repeater and a base unit, the electronic apparatus stores the voice data transmitted from the base unit into one speech buffer and stores voice data transmitted from the repeater into the other speech buffer, and uses the voice data of a lower error rate. This maintains high speech quality. In case the electronic apparatus roams from a second wireless network formed around the repeater to a first wireless network formed around the base unit, smooth roaming is provided without degrading the speech quality by using the voice data of a lower error rate stored in either of the two speech buffers, even when the conversation state is gradually degraded and more errors are detected in the received data.

5. An electronic apparatus connectable to a plurality of wireless networks, said electronic apparatus comprising:
-
a communicator for communicating with another electronic apparatus directly or via a repeater; an error detector for detecting an error of first data received directly from said other electronic apparatus or for detecting an error of second data received from said other electronic apparatus via said repeater; a selector for selecting data from said first data or said second data depending on the result detected by said error detector; a controller, when said electronic apparatus is in a position where said electronic apparatus is communicable with said first electronic apparatus and said second electronic apparatus, for outputting a voice based on said selected data; and at least two buffers for temporarily storing the received data, wherein; said electronic apparatus stores the data directly received from said first electronic apparatus into one buffer and stores the data received via said second electronic apparatus into the other buffer respectively, and when the electronic apparatus is in a position where the electronic apparatus is communicable with said first electronic apparatus and said second electronic apparatus, said electronic apparatus reads and reproduces data from a buffer selected based on the error rate detected by said detection means. - View Dependent Claims (6, 7, 8)

9. A wireless network system comprising:
-
a first electronic apparatus connected to a first wireless network and connectable to a second wireless network; a second electronic apparatus connected to said second wireless network and connectable to said first wireless network, said second electronic apparatus performing data relay between said first wireless network and said second wireless network; and a third electronic apparatus connected to said first wireless network and said second wireless network, said third electronic apparatus comprising a calculator for calculating an error rate of data received from said first electronic apparatus and said second electronic apparatus;
wherein;said third electronic apparatus has a feature to transmit to said first electronic apparatus a release notice indicating that communications with said second electronic apparatus is unavailable in case said error rate of said data received from said electronic apparatus has reached or exceeded a predetermined value, and said first electronic apparatus has a feature to transmit a release notice to said second electronic apparatus in case a release notice is received from said third electronic apparatus.

10. An electronic apparatus connectable to a plurality of wireless networks, said electronic apparatus comprising:
-
a radio section (I) for directly communicating with a first electronic apparatus which belongs to a first wireless network, receiving first data from said first electric apparatus and outputting said first data, or (ii) for communicating with said first electronic apparatus via a second electronic apparatus which belongs to a second wireless network, receiving second data from said second electric apparatus and outputting said second data, said second electronic apparatus performing data relay between said first wireless network and said second wireless network; an error counter for counting the number of errors of first data outputted from said radio section; and a selector for selecting data from said first data or said second data, wherein when said number of errors has reached or exceeded a predetermined value while communicating with said first electronic apparatus, said selector selects said second data and said radio section starts communicating with said second apparatus. - View Dependent Claims (11)
