    摘要： Methods for performing various operations via unlicensed mobile access (UMA) radio link control (URLC) messages in an unlicensed mobile access network (UMAN). The UMAN comprises a first radio access network that may be employed for accessing data services provided by a core network comprising a second radio access network. URLC messages are exchanged between mobile stations (MSs) and UMA network controllers (UNCs) to perform various operations associated with the UMAN. An MS may access the UMAN via a wireless access point (AP) that is communicatively coupled to a UNC via an IP network. The URLC messages are sent between MSs and UNCs using an Up interface comprising a set of layered protocols over an underlying IP transport.

    摘要： Various embodiments for maintaining a reliable time clock on a mobile computing device are described. In one embodiment, a mobile computing device may optionally enable and disable acquisition of time data from multiple sources including a mobile network and a global positioning system (GPS) satellite. The mobile computing device may comprise a time clock to display local time information derived from stored time data and may prioritize the multiple sources for writing and overwriting the stored time data to converge to the most reliable time data available. Other embodiments are described and claimed.
