DYNAMICALLY SWITCHING BETWEEN CALL PATHS FOR OUTGOING CALLS COMPRISING PBX-PATH FOR ENTERPRISE CALLS AND CELLULAR-PATH FOR PERSONAL CALLS

摘要

The application relates to mobile phones which are used for both enterprise and personal calls. A conventional phone may be used for both type of calls, referred to as "operating modes". However, currently, the mode to be used must be performed manually prior to a call being placed or be configured in a predetermined manner based upon known conditions that generally indicate which operating mode should be used. In the first case, the user is always required to place the communications device in the proper operating mode prior to each call being placed using the communications device. In the second case, a current configuration to set the communications device may be a time of day in which when a call is made from the communications device between a certain time (e.g., 8:30am - 5:00pm), the enterprise mode is used. Outside the time window, the communications device may be set with the personal mode. Thus, the user may always be forced to utilize a particular operating mode such as always using the enterprise mode despite being a personal call during the predetermined time window. The application proposes to determine the operating mode in a dynamic manner by a so-called Wireless Services Manager Arrangement WSMA. Therefore, the calling phone transmits to the WSMA e.g. the phone number of the party to be called (215). The WSMA consults a database comprising the phone numbers of all parties directly or indirectly related to the enterprise. When the phone number is found in the database, the phone call is considered to be an enterprise call, otherwise it will be considered to be a personal call. The WSMA transmits a corresponding reply to the calling phone (230) which subsequently either dials over the cellular network (245) in case of a personal call or dials via a PBX (240) in case of an enterprise call.
