Abstract

Methods and systems provide integrated voice and data services utilizing wired cordless access with unlicensed/unregulated connectivity sources. A digital cordless telephone operates over unlicensed/unregulated spectrum in conjunction with one or more wireless access points (WAP) that are installed in homes, businesses, entertainment venues, and the like. The WAPs are connected to a communications service provider'"'"'s broadband packet data network. A user may use the device when they are in range of another wireless access point in a public or private building that also is connected to their communications service provider'"'"'s broadband packet data network.

Claims

1. A system, comprising:

a memory that stores computer-executable instructions; and

a processor, communicatively coupled to the memory, that facilitates execution of the computer-executable instructions to at least;

receive information of a call directed to a telephone number assigned to a digital cordless handset and a cellular telephone;

generate a termination attempt trigger based on the information;

initiate, based on the termination attempt trigger, the call to the cellular telephone before initiation of the call to the digital cordless handset based on a delay that is associated with a cellular network;

detect whether the call was answered via the digital cordless handset;

send, via a first wireless access point of a first wireless network that is associated with a voice over internet protocol and a first service provider, a data packet of the call directed to the digital cordless handset based on a determination that the call was answered via the digital cordless handset;

determine, based on a medium access control address received from the digital cordless handset via a second wireless access point of a second wireless network that is associated with the voice over internet protocol and a second service provider that is different from the first service provider, that the digital cordless handset moved from a first wireless coverage area of the first wireless network to a second wireless coverage area of the second wireless network; and

send, via the second wireless access point, another data packet of the call directed to the digital cordless handset based on a determination that the medium access control address is assigned an internet protocol address that corresponds to the second wireless access point.

2. The system of claim 1, wherein the call is an incoming call.

3. The system of claim 1, wherein the call is an outgoing call.

4. The system of claim 1, wherein the processor further facilitates the execution of the computer-executable instructions to:

query, based on the termination attempt trigger, whether a data store includes subscriber information associated with the call; and

initiate the call to the digital cordless handset and the cellular telephone based on the subscriber information.

5. The system of claim 1, wherein the processor further facilitates the execution of the computer-executable instructions to send, in response to the termination attempt trigger, a query to a service control point.

6. The system of claim 5, wherein the processor further facilitates the execution of the computer-executable instructions to:

interrogate a data store of a public switched telephone network based on the query; and

determine whether the call is associated with a dialup telephone service.

7. The system of claim 5, wherein the processor further facilitates the execution of the computer-executable instructions to format the query according to a signaling system 7 protocol.

8. The system of claim 1, wherein the first wireless network and the second wireless network are associated with different Bluetooth networks.

9. The system of claim 1, wherein the cellular network is associated with a global system for mobile communications network.

10. The system of claim 1, wherein the processor further facilitates the execution of the computer-executable instructions to:

communicatively couple a mobile switching center of a cellular network to the first wireless access point utilizing a signaling system 7 switching protocol.

11. The system of claim 1, wherein the processor further facilitates the execution of the computer-executable instructions to:

service the call utilizing a first wireless transmission area that is associated with a first voice over internet protocol session and a second wireless transmission area that is associated with a second voice over internet protocol session.

12. A method, comprising:

communicatively coupling, by a system including a processor, a signal transfer component of a network to;

a first wireless access point of a first wireless network associated with a voice over internet protocol and a first service provider via a first communication link, and

a mobile switching center of a cellular network via a second communication link;

generating, by the system, a termination attempt trigger in response to receiving a call directed to a telephone number of a digital cordless handset associated with the first wireless network and a cellular telephone associated with the cellular network;

routing, by the system, information of the call directed to the cellular telephone via the mobile switching center before routing the information directed to the digital cordless handset via the first wireless access point based on a delay that is associated with the cellular network;

sending, by the system, data of the call directed to the digital cordless handset utilizing the first wireless access point in response to determining that the call was answered via the digital cordless handset;

determining, by the system, a relocation of the digital cordless handset from a first wireless coverage area associated with the first wireless access point to a second wireless coverage area associated with a second wireless access point of a second wireless network associated with the voice over internet protocol and a second service provider distinct from the first service provider in response to a medium access control address being determined to have been received from the digital cordless handset by the second wireless access point; and

sending, by the system via the second wireless access point, other data of the call directed to the digital cordless handset in response to the medium access control address being determined to be assigned an internet protocol address corresponding to the second wireless access point.

13. The method of claim 12, further comprising:

obtaining, by the system, identification information from the digital cordless handset;

determining, by the system, a service based on the identification information; and

providing, by the system via the first wireless access point and the second wireless access point, respective portions of the service to the digital cordless handset during the call.

14. The method of claim 12, further comprising:

establishing, by the system, a voice over internet protocol session via the first wireless access point, the second wireless access point, and the digital cordless handset based on an internet protocol address.

15. The method of claim 12, further comprising:

servicing, by the system, an outgoing call via an Institute of Electrical and Electronics Engineers 802.11b wireless connection between the digital cordless handset and at least one of the first wireless access point or the second wireless access point.

17. The method of claim 12, further comprising:

querying, by the system via a service control point, subscriber information based on the termination attempt trigger;
