Network-requested activation of packet data protocol context
View Patent ↗A method for activating a packet data protocol context in a wireless telecommunication system comprising at least one terminal and at least one network element. The network element is arranged to deliver packets between the wireless telecommunication system and other packet data networks. Direction-specific service conditions are stored in the telecommunication system for packets received by the network element and designated to at least one terminal. The stored direction-specific service conditions determine what kind of service is provided for packets received from different directions. The direction of a received packet is determined and the direction-specific service conditions relating to the determined direction of the packet are checked. The packet data protocol context is activated according to the direction-specific service conditions.
1. A method for processing data packets, the method comprising:
receiving a data packet, wherein the data packet is directed toward a mobile terminal;
identifying a characteristic of the received data packet;
determining whether the identified characteristic of the data packet satisfies a condition associated with the mobile terminal; and
activating a packet data protocol context if the identified characteristic satisfies the condition.
2. The method of claim 1 , further comprising denying activation of the packet data protocol context if the identified characteristic does not satisfy the condition.
3. The method of claim 1 , wherein the identified characteristic comprises a source node of the data packet, and further wherein the condition comprises a source node-related service condition.
4. The method of claim 1 , wherein the identified characteristic comprises a route used by the data packet, and further wherein the condition comprises a route-related service condition.
5. The method of claim 1 , further comprising receiving the condition from a subscriber associated with the mobile terminal.
6. The method of claim 1 , wherein the identified characteristic comprises a source address of the data packet, and further wherein the condition comprises a source address-related service condition.
7. The method of claim 6 , wherein the source address-related service condition is based at least in part on an address space with one or more acceptable source addresses.
8. The method of claim 1 , wherein the identified characteristic comprises an application associated with the data packet, and further wherein the condition comprises an application-related service condition.
9. The method of claim 1 , further comprising determining one or more of a type of quality of service (QoS), a type of packet data protocol, and a charge based at least in part on the identified characteristic.
10. The method of claim 9 , wherein the one or more of the type of quality of service, the type of packet data protocol, and the charge are determined based at least in part on the condition.
11. The method of claim 1 , wherein the identified characteristic comprises a node from which the data packet is received, and further wherein the condition comprises a node-related service condition.
12. The method of claim 1 , further comprising transmitting the data packet to the mobile terminal using the packet data protocol context if the packet data protocol context is activated.
13. A network element comprising:
a receiver configured to receive a data packet, wherein the data packet is directed toward a mobile terminal; and
a computing device operatively coupled to the receiver, wherein the computing device is configured to execute instructions to cause the computing device to perform operations comprising:
identifying a characteristic of the received data packet;
determining whether the identified characteristic of the received data packet satisfies a condition; and
activating a packet data protocol context if the identified characteristic satisfies the condition.
14. The network element of claim 13 , further comprising a memory operatively coupled to the computing device, wherein the memory is configured to store the condition.
15. The network element of claim 13 , wherein the identified characteristic comprises a source node of the data packet, a route used by the data packet, a source address of the data packet, an application associated with the data packet, or a node from which the data packet is received.
16. The network element of claim 13 , wherein the condition relates to one or more of a source node of the data packet, a route used by the data packet, a source address of the data packet, an application associated with the data packet, and a node from which the data packet is received.
17. The network element of claim 13 , wherein the operations further comprise ignoring the data packet if the identified characteristic does not satisfy the condition.
18. The network element of claim 13 , wherein the condition is specific to the mobile terminal.
19. The network element of claim 13 , further comprising a transmitter configured to transmit the data packet to the mobile terminal if the packet data protocol context is activated.
20. An article of manufacture including a computer-readable medium having instructions stored thereon that, if executed by a computing device, cause the computing device to perform operations comprising:
identifying a characteristic of a received data packet, wherein the data packet is directed toward a mobile terminal;
determining whether the identified characteristic of the data packet satisfies a condition associated with the mobile terminal; and
activating a packet data protocol context if the identified characteristic satisfies the condition.
21. The article of manufacture of claim 20 , wherein the condition comprises one of a direction-specific service condition or a service-type service condition.
22. The article of manufacture of claim 20 , wherein the identified characteristic comprises a direction.
23. The article of manufacture of claim 20 , wherein the identified characteristic comprises a port number associated with the data packet.
24. The article of manufacture of claim 20 , wherein the operations further comprise ignoring the data packet if the identified characteristic fails to satisfy the condition.
