Abstract
Abstract The present invention relates to communications systems comprising multiple access technologies, and more especially it relates to access technology allocation of communications in such communications systems. Particularly, it relates to allocation of a plurality of communication flows to one or more of a plurality of access technologies avail able in the communications system. Access selection based upon stored one or more preference values is disclosed.

Claims Analysis
Total Claims: 30
Claim 1
Independent Claim
74 words
A method of access selection in a multi-access communications system for allocating one or more communication flows to one or more of a plurality of access technologies, the method comprising, for one or more of the communication flows: determining one or more preference values of each of the plurality of access technologies, the preference values reflecting whether it is advantageous to allocate additional communication flows to the access technology; and storing the preference values.
Claim 2
Independent Claim
74 words
A method of access selection in a multi-access communications system for allocating one or more communication flows to one or more of a plurality of access technologies, the method comprising, for one or more of the communication flows: determining one or more preference values of each of the plurality of access technologies, the preference values reflecting whether it is advantageous to allocate additional communication flows to the access technology; and storing the preference values.
Claim 3
Dependent Claim
32 words
The method of claim 1 wherein storing the one or more preference values comprises storing a preference value linked to a bundle of one or more communication flows affecting the preference value.
Claim 4
Dependent Claim
28 words
The method of claim 2 further comprising including a communication flow allocated to an access technology in the bundle linked to a preference value of the access technology.
Claim 5
Dependent Claim
27 words
The method of claim 2 further comprising updating a preference value when a communication flow is allocated to the access technology to which the preference value refers.
Claim 6
Dependent Claim
27 words
The method of claim 2 further comprising updating a preference value when a communication flow in the bundle linked to the preference value is ended or terminated.
Claim 7
Dependent Claim
51 words
The method of claim 1 further comprising associating the one or more preference values with one or more information qualifiers indicating at least one of a condition, a requirement, a lack of corresponding conditions or a lack of corresponding requirements, associated with the communication flows for allocation to the access technology.
Claim 8
Dependent Claim
42 words
The method of claim 1 further comprising associating the one or more preference values with one or more information qualifiers indicating at least one of a particular condition and a particular requirement under which the one or more preference values are relevant.
Claim 9
Dependent Claim
16 words
The method of claim 1 further comprising executing a preliminary candidate allocation for all communication flows.
Claim 10
Dependent Claim
19 words
The method of claim 8 further comprising associating a preliminary candidate allocation with a preliminary candidate preference value update.
Claim 11
Dependent Claim
32 words
The method of claim 8 further comprising determining, over the available access technologies, a greatest preference value increase of preliminary candidate update for each communication flow or each pair of communication flows.
Claim 12
Dependent Claim
33 words
The method of claim 10 further comprising: ordering the communication flows according to their greatest preference value increase; and sequentially allocating the communication flows to the access technologies in sequence of the ordering.
Claim 13
Dependent Claim
29 words
The method of claim 1 further comprising selecting the access technology based on the preference values of communication flows associated with different user terminals or Personal Area Networks (PANs).
Claim 14
Dependent Claim
74 words
Access selection equipment for allocating one or more communication flows to one or more of a plurality of access technologies, the access selection equipment comprising: a processor configured to process one or more preference values determined for each of the plurality of access technologies; and memory configured to store the one or more determined preference values, wherein the preference values reflect whether it is advantageous to allocate additional communication flows to the access technology.
Claim 15
Dependent Claim
74 words
Access selection equipment for allocating one or more communication flows to one or more of a plurality of access technologies, the access selection equipment comprising: a processor configured to process one or more preference values determined for each of the plurality of access technologies; and memory configured to store the one or more determined preference values, wherein the preference values reflect whether it is advantageous to allocate additional communication flows to the access technology.
Claim 16
Dependent Claim
25 words
The access selection equipment of claim 13 further comprising an input configured to receive at least one of an allocation policy or a preference value.

Claim 18
Dependent Claim
32 words
