METHOD FOR NETWORK CONTROLLED ACCESS SELECTION
First Claim
1. An Access Selection Server (ASS) (201, 301, 404, 409, 603, 706, 802, 902) comprising storing means and software, the ASS being adapted for location in a communication network comprising at least one User Equipment (UE) (212, 302, 701, 801, 901) and communication nodes (204, 401, 406, 206, 407, 601, 602, 704, 705, 211, 202) characterized by the ASS being arranged to allow each UE to have multiple accesses to at least one Packet Data Network Gateway (PDN GW) (211) being part of the communication network, each access comprising one IP-session (502, 503), the ASS (201, 301, 404, 409, 603, 706, 802, 902) further being arranged to store information of all accesses for each UE (212, 302, 701, 801, 901) in the communication network and information of overall load status of the communication network in the storing means by means of collecting information through interactions with the communication nodes (204, 401, 406, 206, 407, 601, 602, 704, 705, 211, 202), the UE and an Access Selection Server subscriber Data Base (ASS DB) (203), and that the ASS is arranged to communicate control messages, based on the stored information, from the ASS to the UE, thereby enabling control of multiple UE-accesses from the ASS.

Abstract
The invention provides an Access Selection Server (ASS) and a method for the same. The invention also provides a User Equipment (UE). The Access Selection Server (ASS) comprises storing means and software and is adapted for location in a communication network comprising at least one User Equipment (UE) and communication nodes. The ASS is also arranged to store information of all accesses for each UE in the communication network and information of overall load status of the communication network in the storing means by means of collecting information through interactions with the communication nodes, the UE and an Access Selection Server subscriber Data Base (ASS DB). The ASS is further arranged to communicate control messages, based on the stored information, from the ASS to the UE, thereby enabling control of multiple UE-accesses from the ASS.

- 1. An Access Selection Server (ASS) (201, 301, 404, 409, 603, 706, 802, 902) comprising storing means and software, the ASS being adapted for location in a communication network comprising at least one User Equipment (UE) (212, 302, 701, 801, 901) and communication nodes (204, 401, 406, 206, 407, 601, 602, 704, 705, 211, 202) characterized by the ASS being arranged to allow each UE to have multiple accesses to at least one Packet Data Network Gateway (PDN GW) (211) being part of the communication network, each access comprising one IP-session (502, 503), the ASS (201, 301, 404, 409, 603, 706, 802, 902) further being arranged to store information of all accesses for each UE (212, 302, 701, 801, 901) in the communication network and information of overall load status of the communication network in the storing means by means of collecting information through interactions with the communication nodes (204, 401, 406, 206, 407, 601, 602, 704, 705, 211, 202), the UE and an Access Selection Server subscriber Data Base (ASS DB) (203), and that the ASS is arranged to communicate control messages, based on the stored information, from the ASS to the UE, thereby enabling control of multiple UE-accesses from the ASS.
- 19. A method for an Access Selection Server (ASS) (201, 301, 404, 409, 603, 706, 802, 902) comprising storing means and software, the ASS being located in a communication network, the communication network comprising at least one User Equipment (UE) (212, 302, 701, 801, 901) and communication nodes (204, 401, 406, 206, 407, 601, 602, 704, 705, 211, 202) characterized by the ASS allowing each UE to have multiple accesses to at least one Packet Data Network Gateway (PDN GW) (211) being part of the communication network, each access comprising one IP-session (502, 503), the ASS (201, 301, 404, 409, 603, 706, 802, 902) further storing information (1002) of all accesses for each UE (212, 302, 701, 801, 901) in the communication network and information of overall load status of the communication network in the storing means by collecting information (1001) through interactions (1001) with the communication nodes (204, 401, 406, 206, 407, 601, 602, 704, 705, 211, 202), the UE and an Access Selection Server subscriber Data Base (ASS DB) (203) and that the ASS communicates control messages (1003), based on the stored information, from the ASS to the UE, thereby enabling control (1003) of multiple UE-accesses from the ASS.
- 37. A User Equipment (UE) (212, 302, 701, 801, 901) arranged to interact with a communication network, characterized in that the UE comprises an ASS-function wherein the UE further is arranged to communicate through an IP-based interface (214, 305) with an ASS (201, 301, 404, 409, 603, 706, 802, 902), the ASS function in the UE being arranged to handle requests from the ASS to perform activation of new accesses and/or modification or deactivation of existing accesses.
