Communication system and method for establishing a connection to a serving network element
First Claim
1. A method, comprising:
- obtaining in a user equipment information about a proxy available in a communication system;
receiving in the user equipment a list of parameters in response to intending to establish a session using the proxy in the communication system, the list of parameters comprising service-related information;
where the information is obtained from, and the list of parameters is received from, a network element, other than the proxy, of an access network of the communication system;
selecting at least one parameter from the list; and
establishing the session via the proxy using the selected parameter,wherein said receiving of the list of parameters comprises receiving the list using a communication channel of the access network of the communication system where the session is to be established, wherein the list is received in a packet data protocol context message, and wherein the list is extracted from at least one database of the network element of the access network of the communication system.

Abstract
The invention relates to a communication system and method wherein a user equipment contains, or is provided with, a list of items of service-related information. The list of service-related information represents a list of service provider names, services and/or service types or the like. When intending to establish or modify a session or connection or use a service, the user equipment selects, in one of the embodiments, an item from the list and performs a DNS query to resolve the name of the selected item to an IP address which then is used for set-up. The list may be provided by an DHCP server or in a PDP context message. The list may comprise one or more service provider default names, in particular for visited and home networks.

4. An apparatus, comprising:
-
at least one processor; and at least one memory including computer program code, where the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus to at least; obtain information about a proxy available in a communication system; receive a list of parameters, the list comprising service-related information; where the information is obtained from, and the list of parameters are received from, a network element, other than the proxy, of an access network of the communication system; select a parameter from the list; establish a session using the parameter, wherein the computer code is configured with the at least one processor to cause the apparatus to receive the list using a communication channel of the access network of the communication system where the session is to be established, wherein the list is received in a packet data protocol context message, and wherein the list is extracted from at least one database of the network element of the access network of the communication system. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11)

12. A computer program embodied on a non-transitory computer-readable medium, the computer program configured to control a processor to perform operations comprising:
-
obtaining in a user equipment information about a proxy available in a communication system; receiving in the user equipment a list of parameters in response to intending to establish a session using the proxy in the communication system, the list of parameters comprising service-related information; where the information is obtained from, and the list of parameters is received from, a network element, other than the proxy, of an access network of the communication system; selecting at least one parameter from the list; and establishing the session via the proxy using the at least one selected parameter, wherein said receiving of the list of parameters comprises receiving the list using a communication channel of the access network of the communication system where the session is to be established, wherein the list is received in a packet data protocol context message, and wherein the list is extracted from at least one database of the network element of the access network of the communication system. - View Dependent Claims (13)

14. A method, comprising:
-
in response to a need to establish a connection between a user terminal and a network element, sending a request message from the user terminal to a dynamic host configuration protocol server; receiving from the dynamic host configuration protocol server a service-related list, wherein the list is received in a packet data protocol context message; selecting a proxy name from the service-related list; sending the selected proxy name from the user terminal to a domain name server; receiving from the domain name server an interne protocol address associated with the selected proxy name; and using the interne protocol address, sending a request from the user terminal to the selected proxy to establish the connection with the network element. - View Dependent Claims (15, 16, 17)
