Abstract: Methods and apparatuses for fault detection in a component associated with an application programming interface platform are provided. In an embodiment, the component is determined to have been invoked to process a transaction. A forward progress counter is monitored to determine whether the component is processing the transaction, wherein the forward progress counter increments at determined intervals when the component is processing the transaction. A test transaction is executed for the component when a determination is made that the forward progress counter has not incremented for a threshold fault period. A fault alarm indicator is generated based on the determination that the forward progress counter has not incremented for the threshold fault period.

Abstract: Wireless communication systems and methods are described that provide location-based social networks to mobile communication devices. Mobile users of the wireless communication system define social networking profiles storing characteristics of the user. The wireless communication system determines a location of a user's mobile communication device and identifies a set of other mobile users that are geographically proximate to the user. The wireless communication system then filters the set of other mobile users based on characteristics of the social networking profiles of the other mobile users, and transmits identifiers of the filtered set of other mobile users to the user's mobile communication device. The mobile communication device then displays the identifiers of the filtered set of other mobile users to the user allowing the user to initiate contact with any of the other mobile users that are of interest.

Abstract: Systems and methods are provided for defining a plurality of services zones within a wireless network and providing common content to users located within a particular service zone. The method comprises defining a plurality of service zones within the wireless network. The service zones are defined for providing location-based services to users within the service zones. The method further comprises identifying common content for a service zone. The method further comprises transmitting the common content to communication devices of a plurality of users located within the service zone.
