Method and apparatus for minimizing setup time for a mobile station
View Patent ↗A mobile station ( 10 ) is coupled to an external network ( 60 ) or to a media gateway ( 50 ). A network resource allocation manager ( 130 ) pre-establishes a communication network ( 100 ) connection of network nodes ( 20 - 50 ). This plurality of communication nodes is assigned ( 150 ) as a complete unit instead of piecemeal sequentially. Based upon communication network node resources and network operator input, a number of the communication nodes or speculative contexts are pre-established ( 148 ).
1. A method for coupling a plurality of mobile stations from a communication network to an external network comprising the steps of:
collecting aggregate data regarding prior connections between the communication network and the external network;
predicting future traffic loading between the communications network and the external network based upon the collected aggregate data;
pre-establishing a plurality of speculative context links between the communications network and the external network based upon the predicted future traffic loading; and
dynamically assigning the plurality of speculative context links as the requests for connections are received from the plurality of mobile stations to thereby establish a connection between the plurality of mobile stations and the external network.
2. The method for coupling a mobile station as claimed in claim 1 , wherein the step of dynamically assigning includes the step of:
setting up the plurality of communication links based upon a plurality of communication network nodes and a network operator input.
3. The method for coupling a mobile station as claimed in claim 2 , further comprising the step of reconstructing the number of pre-established communication links according to changes in the plurality of communication network nodes and to the network operator input.
4. The method for coupling a mobile station as claimed in claim 1 , wherein the step of collecting aggregate data comprises collecting at least one of:
a) subscriber service profiles and subscriber usage history;
b) current active sessions and contexts;
c) context destinations and sources; and
d) quality of service class usage, bandwidth usage and service usage.
5. The method for coupling a mobile station as claimed in claim 1 , wherein there is further included a step of developing statistics from the collected aggregate data, the statistics including at least one of:
a) a most probable quality of service class;
b) most probable data rate;
c) a near term request probability; and
d) a mean time to data request.
6. The method for coupling a mobile station as claimed in claim 1 , wherein the step of predicting future traffic loading comprises determining at least one of:
a) quality of service class;
b) service category;
c) bandwidth range;
d) network path hop;
e) time of day and day of week;
f) station and station classification and station group; and
g) radio access network and radio access network allocation group.
7. The method for coupling a mobile station as claimed in claim 1 , wherein there is further included the step of:
specifying a number of pre-established communication links in the plurality of communication links.
8. The method for coupling a mobile station as claimed in claim 1 , wherein the step of pre-establishing includes the step of coupling a radio access network to a serving GPRS support node.
9. The method for coupling a mobile station as claimed in claim 8 , wherein there is further included the step of coupling the serving GPRS support node to a gateway GPRS support node.
10. The method for coupling a mobile station as claimed in claim 9 , wherein there is further included the step of coupling the gateway GPRS support node to a border gateway for coupling to the external network.
11. The method for coupling a mobile station as claimed in claim 9 , wherein there is further included the step of after a session invite request, coupling the mobile station via a radio access network.
12. The method for coupling a mobile station as claimed in claim 9 , wherein there is further included the step of after a session invite request, coupling the gateway GPRS support node via a media server gateway for coupling to the external network.
13. An apparatus for coupling a plurality of mobile stations to an external network comprising:
a radio access network configured to receive requests for data services from the plurality of mobile stations;
a plurality of communication network nodes in communication with the radio access network and configured for coupling to the external network; and
a resource allocation manager coupled to at least some of the plurality of communication network nodes, wherein the resource allocation manager is configured to collect aggregate data regarding prior connection between the plurality of communications network nodes and the external network, to predict future traffic loading between the plurality of communications network nodes and the external network based upon the collected aggregate data, to pre-establish a plurality of speculative context links between the plurality of communications network nodes and the external network based upon the predicted future traffic loading, and to dynamically assign the plurality of speculative context links as requests for data services are received from the plurality of mobile stations to thereby establish connections between the plurality of mobile stations and the external network.
14. The apparatus for coupling a plurality of mobile stations as claimed in claim 13 , wherein the aggregate data comprises at least one of:
a) subscriber service profiles and subscriber usage history;
b) current active sessions and contexts;
c) context destinations and sources; and
d) quality of service class usage and bandwidth usage and service usage.
