The technology downloads and upgrades terminal software of a communications device over-the-air in a efficient and fail-safe manner. The communication device is provided with radio software from a server via a wireless network including a number of access networks. A download is initiated of radio software designed for a first of two different radio access technologies of the communication device. One of the two radio access technologies of the communication device is selected for downloading the software. The radio software is downloaded via the selected available radio access technology. The radio software designed for the first radio access technology is stored in memory.

Downloading and upgrading terminal software over the air of a wireless device

An enhanced radio network controller (RNC) node of a radio access network stores context information for a user equipment unit which is in a Connected Mode, and initiates a cell update-prompting message which is transmitted the user equipment unit. The stored context information is used by the context-enhanced radio network controller (RNC) node for addressing the cell update-prompting message to the user equipment unit. After the user equipment unit (which is in its Connected Mode) performs the prompted cell update procedure, such user equipment unit (UE) can be paged with a conventional paging message. The invention with its context-enhanced radio network controller (RNC) node is particularly suitable to user equipment units which are in a critical state of the Connected Mode, such as (for example) either a CELL_PCH state or a URA_PCH state of the Connected Mode.
