摘要： Network connections that are used in routing VoIP session to their end destination are monitored to determine when a call fails to reach its destination. When a network failure is detected, the call is automatically routed to another device that is not dependent on the failed network connection. The call may be automatically rerouted to one or more secondary numbers, such as a mobile telephone number and/or a PSTN number.

摘要： Providing mobile station time-based services in a cellular wireless communication network. A servicing entity initiates time-based services for the mobile station by querying a Home Location Register (HLR) serving the mobile station to return current mobile station time and time zone (TTZ) information including at least one of the mobile station's local time, local date, a time difference between Greenwich Mean Time (GMT) and the local time. The HLR queries a mobile station serving VLR for the TTZ information. Upon receipt of a TTZ response message, the HLR transmits the TTZ information to the servicing entity. The TTZ information is filtered based on at least one mobile station defined rule to derive a mobile station time-based selective presence or availability. The servicing entity provides the time-based service based on the mobile station TTZ information and the mobile station time-based selective presence.
