Access network selection in a multi-access network environment
First Claim
1. A method of access network selection in a multi-access network environment with one or more 3rd Generation Partnership Projection (3GPP) access networks and one or more non-3GPP access networks to which user equipment directly connect in order to access another network, the method comprising the following steps implemented by an entity in the environment that has one or more processors:
- determining preferences with which a 3GPP access selection function selects a 3GPP access network from said one or more 3GPP access networks; and
as part of implementing at least a portion of an Access Network Discovery and Selection Function (ANDSF), selecting based on said preferences an access network from among said one or more 3GPP access networks and said one or more non-3GPP networks.

Abstract
Novel techniques of access network selection in multi-access network environment are provided, which allow for avoiding access selection loops for independent access selection processes. The multi-access network environment provides a first access selection function, e.g. a 3GPP access selection function, and a second access selection function, e.g. an ANDSF based access selection function. At least a portion of the first access selection function may be implemented by a network component. At least a portion of the second access selection function may be implemented by a user equipment, e.g. a mobile terminal. According to the proposed concepts, a selection priority information of the first access selection function is made available to the second access selection function.

13. An entity in a multi-access network environment with one or more 3rd Generation Partnership Projection (3GPP) access networks and one or more non-3GPP access networks to which user equipment directly connect in order to access another network, the entity comprising:
a processor and a memory, said memory containing instructions executable by said processor whereby said entity is configured to; determine preferences with which a 3GPP access selection function selects a 3GPP access network from said one or more 3GPP access networks; and as part of implementing at least a portion of an Access Network Discovery and Selection Function (ANDSF), select based on said preferences an access network from among said one or more 3GPP access networks and said one or more non-3GPP networks. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A computer program product stored on a non-transitory computer readable medium and comprising program code that when executed on a processor of an entity in a multi-access network environment controls the entity to perform access network selection, the multi-access networks having one or more 3rd Generation Partnership Projection (3GPP) access networks and one or more non-3GPP access networks to which user equipment directly connect in order to access another network, the program code causing the entity to:
-
determine preferences with which a 3GPP access selection function selects a 3GPP access network from said one or more 3GPP access networks; and as part of implementing at least a portion of an Access Network Discovery and Selection Function (ANDSF), select based on said preferences an access network from among said one or more 3GPP access networks and said one or more non-3GPP networks.
