Abstract

An Internet Priority Service (IPS) provides to authorized users priority access to communication over the Internet during emergencies. Transmission of data packets from an authorized user that accesses the IPS are given priority for transmission over the Internet. The level of priority given to a data packet depends on the type of application associated with the data packet. Each user or group of users may also be given a respective IPS level of priority. Furthermore, for a particular authorized user, access to the IPS may be limited to a specific number of application types, which for example do not have high bandwidth requirements. Assigning different priority levels as a function of application type and user or group of users, and limiting IPS access to specific application types allows efficient methods of emergency communication to be implemented over the Internet during emergencies.

Claims

1. A network device for participating in providing an Internet priority service for transmission of data packets each associated with an application type of a plurality of application types, the network element comprising:

an IPS (Internet priority Service) function adapted to;

a) for each data packet;

i) determine which application type is associated with the data packet; and

ii) determine a priority level for transmission of the data packet, the priority level being a function of the application type associated with the data packet; and

b) transmit the data packets according to the priority levels of the data packets.

2. A network element according to claim 1 wherein for each data packet the IPS function is further adapted to:

determine a user or group associated with the data packet, the priority level for transmission of the data packet also being a function of the user or group associated with the data packet.

3. A network element according to claim 2 wherein for each of a plurality of users or groups of users, the user or group of users is assigned an IPS level of priority, and wherein for a first user or group of users of the plurality of users or groups of users the priority level for transmission of data packets associated with a first application type is higher than the priority level for transmission of data packets associated with a second application type assigned to a second user or group of users of the plurality of users and groups, the IPS level of priority of the second user or group of users being higher than the IPS level of priority of the first user or group of users.

4. A network element according to claim 1 wherein the IPS function is adapted to transmit the data packets in a hierachical manner by:

first transmitting the data packets having a higher priority level and then progressively transmitting the data packets having a lower priority level.

5. A network element according to claim 4 wherein to transmit the data packets according to the priority levels of the data packets for each data packet the IPS function is further adapted to:

mark the date packet with an indicator of the priority level for transmission of the data packet for allowing other network elements to transmit the data packet according to the priority level for transmission of the data packet.

6. A network element according to claim 3 wherein for each data packet, to determine the priority level for transmission of the data packet the IPS function is adapted to:

if the application type associated with the data packet is from a subset of application types of the plurality of application types, select a priority level that provides priority services for transmission of the data packet, the subset of application types being a respective subset of application types for the user or group; and

if the application type associated with the data packet is not from the respective subset of application types for the user or group, select a priority level that provides no priority services for transmission of the data packet.

7. A network element according to claim 1 wherein the IPS function is further adapted to:

responsive to invocation of an application by a user authorized to use the Internet priority service, confirm with the user whether associated data packets associated with the application require the Internet priority service; and

if the associated data packets require the Internet priority service, provide the Internet priority service for the associated data packets.

8. A network element according to claim 1 wherein the data packets comprise application fields each containing at least one indicator of an application type indicator and a priority indicator, and wherein for each data packet the IPS function is adapted to determine the priority level for transmission of the data packet using the at least one indicator.

9. A network element for participating in providing an Internet priority service, the network element comprising:

an IPS (Internet Priority Service) management function adapted to;

provide user access to the Internet priority service for at least one application type of a plurality of application types, each one of the plurality of application types having a respective associated priority level for transmission, the respective associated priority level of at least one of the plurality of application types being different than the priority level of at least one other application type of the plurality of application types.

10. A network element according to claim 9 wherein the IPS management function is further adapted to:

receive a request from a user requesting the Internet priority service; and

verify whether the user request is valid, the user access being provided to the user only if the request is valid.

11. A network element according to claim 9 wherein the at least one application type comprises fewer application types than the plurality of application types.

12. A network element according to claim 9 wherein to provide the user access to the Internet priority service the IPS management function is further adapted to send information to other network elements indicating that the access to the priority service is enabled.

13. A network element according to claim 9 comprising a proxy function adapted to serve as a proxy for applications invoked remotely.

14. A network element according to claim 13 wherein the proxy function is further adapted to provide a secure link for access by users invoking the Internet priority service.

15. A network element according to claim 14 wherein the proxy function is further adapted to provide the secure link using an SSL (Secure Socket Layer) protocol.

16. A network element according to claim 15 comprising an IPS function adapted to:

a) for each data packet of a plurality of data packets, the data packet being associated with an associated application type of the plurality of application types;

i) determine which associated application type is associated with the data packet; and

ii) determine the respective associated priority level for transmission from the associated application type associated with the data packet, the respective associated priority level for transmission being a function of the associated application apse associated with the data packet; and

b) transmit the data packets according to the priority levels of the data packets.

17. In a network element, a method of providing an Internet priority service for transmission of data packets each associated with an application type of a plurality of application types, the method comprising:

b) for each data packet;

i) determining which application type is associated with the data packet; and

ii) determining a priority level for transmission of the data packet, the priority level being a function of the application type associated with the data packet; and

b) transmitting the data packets according to the priority levels of the data packets.

18. In a network element, a method of participating in providing an Internet priority service, the method comprising:

providing user access to the Internet priority service for at least one application type of a plurality of application types, each one of the plurality of application types having a respective associated priority level for transmission, the respective associated priority level of at least one of the plurality of application types being different than the priority level of at least one other application type of the plurality of application types.
