WILLCOM core module forum and the call demonstration which is W - SIM in Android

Android exhibited a demonstration of a call by W - SIM to a WILLCOM core module forum (WCM) by a reference board for PHS terminal development which moves.

I make it clear that a WILLCOM core module forum made Android where Open Handset Alliance (OHA) opens and offers it on November 27th move on the reference board for PHS development. This was the stage which tried movement of Android on the hardware first as technical inspection, but the demonstration which can do a sound call via W - SIM newly was opened on the 6th.

Something by which demonstration has technical test and inspection for its object. The state which can do sending and arrival control was shown this time, and an arrival during application use was also achieved. A sound call control part in GSM included in SDK in Android is to put software of middle control between W - SIM in the condition, and a sound call is achieved. Therefore UI for GSM included in Android is used for an user interface on the screen. Further I say the state that Android isn't making big alterations in itself by this demonstration but screen control was adjusted for reference boards. Trusting development can continue in order to do packet communication in W - SIM from now on.

The Fujitsu software technologies which are a member of a built-in Linux working group of a WILLCOM core module forum and a free scale semiconductor are dealing with development of the demonstration environment. A reference board with i.MX31 of a free scale semiconductor (ARM11) (Skuld/SUKURUDO) was used for the environment that I moved like last demonstration. Movement of CPU is 532MHz.

Sound call demonstration chose a GSM control part and W - SIM as the software it bridges, and was achieved, but it was said that they might need joining to OHA to need RIL (Radio Interface Layer) software and receive a way to RIL according to the person in charge to make sure that W - SIM can be controlled directly on the Android side. A WILLCOM core module forum doesn't participate in itself in OHA, and I say that it'll be considered from now on whether you participate while being based on will of a member enterprise.

* What kind of imagination can you have by demonstration?

Mr. Junji Kondo, the Fujitsu software specific engineering group built-in project project section chief of technologies who has developed the demonstration environment actually, "What kind of imagination can a member of a WILLCOM core module forum have by this demonstration?", the significance of the demonstration was told, but also I also pointed out "When RIL was not, the further down (in-depth development of sound call control) was difficult."

A stance of the meaning of the demonstration opening to the public and a WILLCOM core module forum was done clearly from Mr. Kasanami 潤 and Mr. Hiroshi Yamada of a WILLCOM core module forum secretariat. Mr. Kasanami is also combined with improvement of celebrity of a WILLCOM core module forum about opening to the public of a series of demonstration ". Celebrity will be also the merit to rise in a member enterprise,", and, they keep making the gentle opinion clear, ", the one a main point of a WILLCOM core module forum is providing with a development environment of the product able to use W - SIM. It's built-in Linux in it and is this Android. When saying when there was an opinion of a member enterprise, did you say that I kept, and the former activity be stopped, that showed that this demonstration is experimental to the end as different talk".

Mr. Yamada, ", a WILLCOM core module forum isn't always connected with a policy in will com. Whether it was the merit for a member enterprise and the user made the stance as a gauge" clear. A member enterprise gave the form to a technical try the said group by which this demonstration is also non profit organization, and it wasn't a consensus of a WILLCOM core module forum, I preceded and made it development and exhibited one experimentally.

An exhibited contest of the application for which SDK was used is held extensively about Android, but also I also help with the point which is an open platform about a development perspective of hardware which corresponds, and there are a lot of unclear points in the present. But, even the country is that the state which moves on the reference board was published, and it's expected that development of each company gains momentum.


The state at which I arrived during Google map use. The telephone number is indicated and a reply can be chosen. It's possible to call using a loudspeaker and a microphone.


Reference board for PHS terminal development by which Android moves. W - SIM is loaded on the lower left.


A Google map is being used in Android. Packet communication was performed by the right wired cable by this demonstration.


Attachment and removal of W which has started- SIM is also supported. When W - SIM was removed, "x" was shown to the screen upper part.
