Embodiment Construction

[0056] A key requirement for a multiple access system is to provide a mechanism for selecting the access (or accesses) that should be used (or not used, enabled or disabled) by the mobile node or user network. It should be possible to perform this access selection while maintaining or scanning for connectivity. Although primarily focused on the selection of accesses used by traffic flows, the selection of accesses for scanning (ie trying to discover the existence of accesses) is also an area of ​​application.

[0057] Thus, access selection mechanisms in the following areas should be supported:

[0058] - Access selection (for traffic flow)

[0059] - access discovery

[0060] In both cases, rules are the basis of the selection mechanism. In order to provide good performance of the selection method, it is important to resolve conflicts between rules or to combine multiple applicable rules based on .

[0061] In embodiments of the invention, the attributes of the rules gov...

Abstract

A method is provided for use in a communications network in which a plurality of accesses are available to a user entity for accessing a network resource, comprising: determining a set of active rules, each rule specifying respective preferences, at least relatively, for at least some of the plurality of accesses, with potential for conflict between the rules of the set concerning which access is most preferred; deriving from the set of active rules a new rule specifying respective preferences, at least relatively, for at least some of the plurality of accesses; and selecting an access for use by the user entity based on the new rule.

Description

technical field [0001] The present invention relates to methods and arrangements for use in communication networks. Background technique [0002] Different types of access technologies (especially wireless) are becoming increasingly ubiquitous, for example in the form of: GSM / GPRS / EDGE, WCDMA / HSPA, CDMA2000, WLAN, WiMAX and soon LTE (EDGE is "GSM Evolved Enhanced Data Rate"; GPRS is "General Packet Radio Service"; GSM is "Global System for Mobile Communications"; WCDMA is "Wideband Code Division Multiple Access"; HSPA is "High Speed ​​Packet Access" WLAN is an abbreviation for "Wireless Local Area Network"; WiMAX is an abbreviation for "Worldwide Interoperability for Microwave Access"; and LTE is an abbreviation for "Long Term Evolution." [third generation] standard). Mobile terminals match the diversity of access technologies by including more access interfaces to allow more free and flexible selection of the access used for each communication session. [0003] In order ...
