Title:	Support of WAP telephony execution environment (WTA) in MEXE release 98

MExE thanks you for your last liaison statement. The MExE group is pleased to learn that WAP security will converge towards MExE security.

From the MEXE group’s point of view, it is very desirable to have a telephony execution environment in a WAP device (classmark 1), however WTA and WAP PKI specifications are not yet available.

The MExE group would like to have support for telephony related functions but in order to do so MExE security requirements must be fulfilled (e.g. several trusted domains, certification management etc.).  MExE may therefore apply restrictions to the use of WTA in MExE devices in order to respect MEXE security requirement (e.g. user permission request, limited access to public library …).

Therefore the MExE group would encourage the WAP Forum to complete the work on WTA and security as quickly as possible so that trusted WTA application can be supported by MExE.
