Method and system for subnet-based transmission of mobile station location
View Patent ↗A method and system for reporting mobile subscriber location is disclosed. Upon receipt of a request to report the location of a given mobile subscriber, a server may identify the subscriber's “buddies” and then determine, for each buddy, whether the buddy is located in the same zone as the given subscriber. The zone may be, for example, a subnet of a network. Additionally, the server may determine whether a rule is set to block reporting of the given subscriber's location to the buddy. Provided that the buddy is located in the same zone as the given subscriber and provided that reporting is allowed, the server may then send a location-reporting message to the buddy, indicating the given subscriber's location, preferably in terms of proximity to the buddy. The server may further receive a reply from the buddy and then send a location-reporting reply message to the given subscriber, indicating the location of the buddy.
1. A location-reporting method comprising: receiving a location-reporting request from a first mobile subscriber; responsive to the request, making a determination that a second mobile subscriber is on a subnet in common with the first mobile subscriber; and
responsive to the determination, sending a location-reporting message to the second mobile subscriber, the location-reporting message indicating a location of the first mobile subscriber that is proximate to a location of the second mobile subscriber.
2. The location-reporting method of claim 1 , wherein making a determination that the second mobile subscriber is on a subnet in common with the first mobile subscriber comprises:
identifying a Mobile IP address of the second mobile subscriber; and
running a software utility to determine the subnet on which the second mobile subscriber is located.
3. The location-reporting method of claim 2 , wherein identifying the Mobile IP address of the second mobile subscriber comprises querying a location system.
4. The location-reporting method of claim 3 , wherein the location system includes presence technology.
5. The location-reporting method of claim 2 , wherein the software utility is Traceroute.
6. The location-reporting method of claim 1 , further comprising:
in response to the request, querying a group data store to identify the second mobile subscriber.
7. The location-reporting method of claim 6 , wherein querying a group data store to identify the second mobile subscriber comprises identifying one or more mobile subscribers defining a group associated with the first mobile subscriber, the second mobile subscriber being a member of the group.
8. The location-reporting method of claim 7 , wherein the group is an instant messaging buddy list established for the first subscriber.
9. The location-reporting method of claim 7 , wherein the group is an address book established for the first subscriber.
10. The location-reporting method of claim 1 , further comprising:
receiving a reply from the second mobile subscriber, after sending the location-reporting message to the second mobile subscriber; and
in response to the reply, sending a location-reporting reply message to the first mobile subscriber, the location-reporting reply message indicating a location of the second mobile subscriber.
11. The location-reporting method of claim 10 , wherein the location-reporting reply message indicates a proximity of the second mobile subscriber to the first mobile subscriber.
12. The location-reporting method of claim 1 , wherein sending the location-reporting message to the second mobile subscriber comprises:
sending the location-reporting message as text in an SMS message to the second mobile subscriber.
13. The location-reporting method of claim 1 , wherein sending the location-reporting message to the second mobile subscriber comprises:
sending a NetAlert message to the second mobile subscriber, the NetAlert message providing the second mobile subscriber with a link to a web site bearing the location-reporting message.
14. The location-reporting method of claim 1 , wherein sending the location-reporting message to the second mobile subscriber comprises:
sending the location-reporting message to the second mobile subscriber in an XML card.
15. The method of claim 14 , wherein the XML card is a choice card that includes a choice item selectable by a user to reply to the location-reporting message.
16. A location-reporting method comprising: receiving a location-reporting request from a first mobile subscriber, the location-reporting request reflecting a request to report a location of the first mobile subscriber to at least a second mobile subscriber; making a determination of whether reporting of the first mobile subscriber's location to the second mobile subscriber is blocked; and if the determination is that reporting of the first mobile subscriber's location to the second mobile subscriber is not blocked, then reporting the first mobile subscriber's location that is proximate to a location of the second mobile subscriber to the second mobile subscriber provided that the second mobile subscriber is on a subnet in common with the first mobile subscriber.
17. The location-reporting method of claim 16 , wherein making a determination of whether reporting of the first mobile subscriber's location to the second mobile subscriber is blocked comprises determining whether a rule is set for the second mobile subscriber indicating that reporting of the first mobile subscriber's location to the second mobile subscriber's location is blocked.
18. The location-reporting method of claim 16 , wherein making a determination of whether reporting of the first mobile subscriber's location to the second mobile subscriber is blocked comprises determining whether the first mobile subscriber is included in a buddy list established for the second mobile subscriber,
wherein reporting of the first mobile subscriber's location to the second mobile subscriber's location is blocked if the first mobile subscriber is not included in the buddy list established for the second mobile subscriber.
19. A location-reporting method comprising: receiving from a first mobile subscriber a request to report the first mobile subscriber's location; responsive to the request, identifying a group of mobile subscribers associated with the first mobile subscriber; with respect to each mobile subscriber in the group, determining whether the mobile subscriber is on a subnet in common with the first mobile subscriber and, if so, sending a location-reporting message to the mobile subscriber, the location-reporting message indicating a location of the first mobile subscriber that is proximate to a location of the second mobile subscriber; receiving from at least a given mobile subscriber in the group a reply to the location-reporting message; and responsive to the reply, sending to first mobile subscriber a location-reporting reply message indicating a location of the given mobile subscriber.
20. The location-reporting method of claim 19 , wherein identifying a group of mobile subscribers associated with the first mobile subscriber comprises:
querying a data store to identify the group of mobile subscribers; and
excluding from the group any mobile subscriber to which reporting of the first mobile subscriber's location is blocked.
21. A system comprising: a processor; data storage; and instructions stored in the data storage and executable by the processor in response to a location-reporting request from a first mobile subscriber, to: make a determination that a second mobile subscriber is on a subnet in common with the first mobile subscriber; and responsive to the determination, send a location-reporting message to the second mobile subscriber, the location-reporting message indicating a location of the first mobile subscriber that is proximate to a location of the second mobile subscriber.
