Abstract
A UMTS extension to the GSM/GPRS RIL is disclosed. The UTMS RIL provides an API set interface for the support of UMTS features such as 3G QoS, secondary PDP contexts call, priority service, voice group call and voice broadcast services, etc. The API set is based on the UMTS AT command interface as defined in 3GPP specification TS 27.007. The architecture of the UMTS RIL is designed as a standard interface with APIs and callback mechanisms that can be used across different platforms and multi-radio hardware such as GSM, GPRS, WCDMA, and HSDPA. The UTMS RIL may enable various applications running on mobile platforms in 2G, 2.5G, and 3G cellular radio stacks to issue commands without knowledge of underlying radio hardware structure.
