Three deals by mobile infrastructure vendors this week demonstrate the growing acceptance of IMS by the industry as a whole:

*Lucent's [NYSE:LU, http://www.lucent.com/] agreement to resell Westell's [NASDAQ:WSTL, http://www.westell.com] TriLink IMS gateway.

*Lucent's acquisition of privately held Mobilitec, provider of content-management software for wireless service providers.

*Sybase's [NYSE:SY, http://www.sybase.com/] acquisition of privately held Mobile 365, a mobile enterprise software and services provider.

Cellular companies plan to use IMS to provide VOIP over their data service, permitting concurrent access to the Internet, effectively making cell carriers ISPs.
