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 and a server. A cell-phone, capable of roaming between regions, is operable to establish a wireless link with the base stations and through the base stations, with the server. The network contains a communication policy determining from which other communication devices a subscriber device can receive voice calls. The communication policy is updated, by the server, based on requests from the subscriber devices. Once a request is received from a subscriber device, the determination whether to update the communication policy can be based on a record of rejections respective to the caller requested to be blocked. Alternatively, the communication policy can be updated according to a trust policy maintained on the server respective to the subscriber device making the request; the trust policy represents the procedure to follow when a request is received from that subscriber device.

Claims

1. A method of processing communications in a voice telephony network having a plurality of subscriber devices and a server;

said method comprising the steps of;

maintaining, at said server, a central common communication policy comprising at least one identifier representing whether reception of a first voice call having said at least one identifier is permissible at said subscriber devices in said network;

maintaining, at each said subscriber device, a local common communication policy;

said local common communication policy corresponding to said central common communication policy;

maintaining, at each said subscriber device, a local override policy for determining whether to permit said first voice call regardless of contents of said local common communication policy;

receiving a second voice call at one of said subscriber devices;

said second voice call having an originator identifier;

receiving a user-input at said one of said subscriber devices representing a marker of said originator identifier;

accessing said local common communication policy at said one of said subscriber devices;

updating said local common communication policy with said originator identifier associated with said marker, such that reception of a third voice call having said originator identifier is impermissible at said one of said subscriber devices; and

sending a request for an update to said server whereby to update said central common communication policy with said originator identifier associated with said marker, and sending updates to said plurality of subscriber devices such that reception of a fourth voice call having said originator identifier is impermissible at said plurality of said subscriber devices, unless said local override policy in said at least another one of said subscriber devices indicates that reception of said fourth voice call having said originator identifier is permissible regardless of said central common communication policy.

2. The method of claim 1 wherein said sending updates comprises the step of:

propagating said central common communication policy to said plurality of subscriber devices such that said local common communication policy at each said plurality of subscriber devices is synchronized with said central common communication policy.

3. The method of claim 2 wherein said propagating step is performed after said step of updating said central common communication policy.

4. The method of claim 2 wherein said propagating step is performed once over a given time period.

5. The method of claim 2 wherein said propagating step is performed after said steps of claim 1 are performed a predetermined number of times.

6. The method of claim 1 wherein said user-input is received prior to said second voice call being answered.

7. The method of claim 1 wherein said user-input is received after said second voice call is answered.

8. The method of claim 1 wherein said originator identifier is a Caller-ID string.

9. The method of claim 1 wherein said identifier in said central common communication policy comprises a Caller-ID string.

10. A computer-readable medium storing a plurality of programming instructions;

said programming instructions implementing a method of processing communications in a voice telephony network having a plurality of subscriber devices and a server;

said method comprising the steps of;

maintaining, at said server, a central common communication policy comprising at least one identifier representing whether reception of a first voice call having said at least one identifier is permissible at said subscriber devices in said network;

maintaining, at each said subscriber device, a local common communication policy;

said local common communication policy corresponding to said central common communication policy;

maintaining, at each said subscriber device, a local override policy for determining whether to permit said first voice call regardless of contents of said local common communication policy;

receiving a second voice call at one of said subscriber devices;

said second voice call having an originator identifier;

receiving a user-input at said one of said subscriber devices representing a marker of said originator identifier;

accessing said local common communication policy at said one of said subscriber devices;

updating said local common communication policy with said originator identifier associated with said marker, such that reception of a third voice call having said originator identifier is impermissible at said one of said subscriber devices; and

sending a request for an update to said server whereby to update said central common communication policy with said originator identifier associated with said marker, and sending updates to said plurality of subscriber devices such that reception of a fourth voice call having said originator identifier is impermissible at said plurality of said subscriber devices, unless said local override policy in said at least another one of said subscriber devices indicates that reception of said fourth voice call having said originator identifier is permissible regardless of said central common communication policy.

11. A subscriber device of a voice telephony network comprising:

a persistent storage device for maintaining, at said subscriber device, a local common communication policy;

said local common communication policy corresponding to a central common communication policy maintained b a server; and

for maintaining, at the said subscriber device, a local override policy for determining whether to permit a first voice call regardless of contents of said local common communication policy;

a radio device for receiving a second voice call at said subscriber device;

said second voice call having an originator identifier;

an input device for receiving a user-input at said subscriber device representing a marker of said originator identifier;

a processor coupled to said persistent storage device and said radio device for accessing said local common communication policy at said subscriber device;

said processor being configured to update said local common communication policy with said originator identifier associated with said marker, such that reception of a third voice call having said originator identifier is impermissible at said subscriber device;

said processor further being configured to send an update request to said server whereby to update said central common policy at said server with said originator identifier associated with said marker, such that reception of a fourth voice call having said originator identifier is impermissible at a plurality of subscriber devices associated with the server unless said local override policy in said at least another one of said subscriber devices indicates that reception of said fourth voice call having said originator identifier is permissible regardless of said central common communication policy; and

said processor further configurable to receive updates from said server whereby to synchronise the local common communication policy at the subscriber device with the central common communication policy at said server.

12. A communications system comprising at least one subscriber device according to claim 11 and at least one policy server.

13. A communications system as in claim 12, in which the policy server comprises:

a network interface for communicating with a plurality of subscriber devices via a voice telephony network interconnecting said devices and said interface;

at least one persistent storage device for maintaining a central common communication policy comprising at least one identifier representing whether reception of a first voice call having said at least one identifier is permissible at said subscriber devices in said network;

a processor interconnecting said interface and said at least one persistent storage device;

said processor for receiving a local common communication policy maintained at one of said plurality of subscriber devices;

said local common communication policy corresponding to said central common communication policy;

said local common communication policy updated at said one of said plurality of subscriber devices to comprise an originator identifier such that reception of a second voice call having said originator identifier is impermissible at said one of said plurality of subscriber devices; and

said processor operable to update said central common communication policy with said originator identifier, such that reception of a third voice call having said originator identifier is impermissible at said plurality of said subscriber devices.
