Abstract

The present invention provides a system and method of modifying policy settings in a network having a plurality of subscriber devices. An embodiment includes a plurality of base stations, each capable of wirelessly transmitting across a geographic region. A cell-phone, capable of roaming between regions is operable to establish a wireless link with the base stations. The network contains a communication policy determining from which other communication devices a subscriber device can receive voice calls. A copy of this policy is stored on each subscriber device as a database and periodically updated as the devices make contact with the base stations or other subscriber devices. When receiving a voice call, the device first determines who the originator of the call is and then determines whether it is allowed to receive the call from that originator according to its policy database. The policy database can be updated either by subscriber devices or by base stations.

Claims

1. A method of processing communications in a network having a plurality of subscriber devices;

said method comprising the steps of;

maintaining, in each subscriber device, a common policy common to all subscriber devices, said policy comprising at least one identifier representing whether reception of a voice call having at least one originator identifier is permissible, said policy being updatable by any of said plurality of subscriber devices;

maintaining, in at least one of said subscriber devices, a local override policy that is unique to said at least one of said subscriber devices;

receiving a voice call at said at least one of said subscriber devices, said voice call having an originator identifier;

accessing said common policy as maintained in said at least one of said subscriber devices;

accessing said local override policy as maintained in said at least one of said subscriber devices;

determining a permissibility, on the said at least one of said subscriber devices, as to whether said voice call is permissible according to said common policy and said local override policy and additionally based on said originator identifier, wherein said local override policy takes precedence over said common policy in said determination; and

accepting or rejecting said call according to said permissibility.

2. The method of claim 1 wherein said determining step comprises the steps of:

determining whether it is permissible to accept said voice call based on said common policy and said originator identifier; and

altering said permissibility according to said override policy.

3. The method of claim 2 wherein said override policy is an opt-out policy, and said altering step is performed such that said permissibility is altered if said override policy for said identifier is to ignore said common policy.

4. The method of claim 2 wherein said override policy is an opt-in policy for those calls deemed impermissible according to said common policy, and said altering step is performed such that said permissibility is altered if said override policy for said identifier is not to follow said common policy.

5. The method of claim 1 wherein said network has at least one server, and said maintaining step is performed at said at least one server.

6. The method of claim 1 wherein said voice call is received over a peer-to-peer connection.

7. The method of claim 1 wherein said network is based on one or more of CDMA, OFDM, AMPS, GSM, GPRS, Bluetooth, infrared, 802.11, and PSTN.

8. A non-transitory computer readable storage medium for storing computer readable instructions for execution by a processor to perform the method of claim 1.

9. A method of updating an override policy maintained in a subscriber device for overriding a common policy for a network having a plurality of subscriber devices;

said method comprising the steps of;

accessing said common policy at one of said subscriber devices;

said common policy having at least one identifier such that reception by said plurality of subscriber devices of a voice call having one of said at least one identifier is impermissible;

marking at least one of said at least one identifiers from said common policy; and

updating said override policy associated with said one subscriber device according to said marked at least one identifier.

10. The method of claim 9 wherein said override policy is an opt-out policy, and said updating step is performed such that reception of a voice call having said at least one identifier is permissible at said one subscriber device.

11. The method of claim 9 wherein said override policy is an opt-in policy, and said updating step is performed such that reception of a voice call having said originator identifier is impermissible at said one subscriber device.

12. A wireless subscriber device for a communications network having a plurality of subscriber devices;

said device comprising;

an interface operable to receive communications;

storage for maintaining a policy;

said policy common to said plurality of subscriber devices;

said policy defining at least one originating identifier from which said computer can determine whether it is permissible for said subscriber device to accept communications;

said storage for further maintaining a local override policy;

said local override policy for overriding at least a portion of said policy, wherein said local override policy takes precedence over said common policy in said determination; and

a microcomputer connected to said interface and said storage, said microcomputer configured to access said common policy and said local override policy and to receive an originating identifier of a communication from said interface, said microcomputer permitting said interface to communicate in accordance with said common policy and said local override policy.
