Methods, systems, and products bridge wireless data transmissions with power-line communications. Should a failure occur in alternating current power, a backup battery maintains the power-line communications. Direct current battery power is used to power a wireless transceiver, thus maintaining both wireless data transmissions and communication during power failures.

Power-line communications

In at least one embodiment, a method includes receiving a first transmission from a device, the first transmission transmitted at a first frequency. In response to receiving the first transmission, a transceiver is disabled and a second transmission is transmitted to the device, the second transmission transmitted at a second frequency. The method further includes receiving a third transmission from the device, the third transmission transmitted at the second frequency.

Interference management using out-of-band signaling

Communication environment switchover may be provided. A received signal strength level may be determined corresponding to a signal sent from a first device and received at a second device. The received signal strength level may be measured at the second device. In addition, the first device may be re-provisioned. For example, the first device may be re-provisioned to communicate in a second environment if the first device is provisioned to communicate in a first environment and if the received signal strength level is greater than a first threshold value. Furthermore, the first device to be re-provisioned to communicate in the first environment if the first device is provisioned to communicate in the second environment and if the received signal strength level is less than a second threshold value. The second threshold value may be less than the first threshold value.

Communication environment switchover

A Service Control Point (SCP) has a call list associated with the main telephone number of a called party. When a calling party attempts to contact the called party by calling the main number, but cannot reach the main number, a Service Switching Point (SSP) fires a trigger. One trigger is a T_No_Answer trigger, which is fired in response to a call to the main number that is not answered within a predefined number of rings. Another trigger is a T_Busy trigger that is fired in response to a call to the main number that is made when the main number is busy. Each trigger causes the SCP to access the call list and to cause the SSP to ring an alternative telephone number associated with the main telephone number. If this attempt to reach the called party also fails, then the SSP again fires the trigger and an attempt is made to connect the calling party to the next number on the call list. If the call list is exhausted before the calling party is connected to a number on the called party's call list, then a message can be played to the calling party. Alternatively, the calling party may be connected to a voice mailbox associated with the called party or may receive a busy tone.

Automatically sequentially ringing alternative telephone numbers

The present invention relates to systems and methods for monitoring and intercepting messages to a voicemail system connected to an AIN or WIN network for screening calls incoming to a landline or wireless telephone. After a call is forwarded to voicemail system, the called party is provided an opportunity to monitor a message as it is spoken into a voicemail system. The called party may intercept the message at any time during delivery of the message to answer the telephone call.

Method and system for screening calls during voicemail messaging

An audio calling name and calling number delivery method is disclosed. When a call is made from a calling party telephone to a called party telephone, a message is sent from an originating service switching point (SSP) associated with the calling party telephone to a terminating mobile switching center (MSC) associated with the wireless called party telephone. Typically, the message comprises the directory number of the calling party telephone. A wireless trigger is tripped at the terminating MSC and, in response, a query is sent to a service control point (SCP). A home location register (HLR) associated with the wireless telephone is queried to determine whether the wireless telephone is available. If the wireless telephone is available, then a name and a number associated with the calling party telephone is forwarded to a service node. The service node places a call to the wireless telephone and an audio annunciation of the name and the number is played to the called party.

Audio calling name and number delivery

A Service Control Point (SCP) has a call list associated with the main telephone number of a called party. When a calling party attempts to contact the called party by calling the main number, a Service Switching Point (SSP) or a Mobile Switching Center (MSC) fires a trigger. The trigger causes the SCP to access the call list and to cause the SSP/MSC to simultaneously ring the main (called) telephone number and at least one alternative telephone number associated with the main telephone number. A simultaneous ring service subscriber can remotely access the SCP to modify a call list, to add or delete a call list and to select an active call list. When a subscriber has multiple call lists, the subscriber can set account parameters to automatically select the active call list, based on various call factors, such as call time and calling party.
