Digital Technology Licensing (DTL) has licensed a key cellphone patent to Sony Ericsson Mobile Communications (Sony Ericsson), reports Trading Markets.
DTL owns US Patent number 5 051 799 titled "Digital Output Transducer", which is an essential patent for the Adaptive Multi-Rate (AMR) codec and other cellular communication standards. The patented technology is also used to assure backward compatibility of cellphone handsets and base stations. Other applications of this patented technology include Bluetooth headsets.
"We are very pleased to grant a licence to Sony Ericsson," said Paul Lerner, General Patent Corporation's senior VP and general counsel. "We will continue with our efforts to license this key patent and to vigorously enforce the intellectual property rights of our client," he concluded.
Cherple facilitates two-way chat
Globaltel Media, a provider of communications software, has pre-released a version of its new application, Cherple, writes CBR Online.
Cherple allows two-way text communication between online computers and mobile wireless cellular devices.
The company claims Cherple technology will eventually provide any of the 1.5 billion global online users with back-and-forth text-message conversations to any of the 3.3 billion wireless devices worldwide using standard SMS messaging.
G1 phones home unexpectedly
Just like ET, the T-Mobile G1 smartphones were desperately trying to phone home (using international SMS) to the original carrier T-mobile, but did not indicate they were doing so, says Australian Personal Computer.
One user on Whirlpool found that his T-Mobile G1 (HTC Dream) made 200 international SMS calls while another user was hit with 1 329 international SMS messages.
It seems the phones were dialling a pre-set T-mobile network number (453), which Virgin mobile treats as an international SMS number at 35c per message. Ironically, Virgin probably never delivered the SMSes but charged the user anyway.
