Network selection and data aggregation with LTE-WLAN aggregation
First Claim
1. A method comprising:
- receiving an LTE-WLAN aggregation (LWA) assistance configuration by a user equipment (UE) in a wireless network, wherein the UE is connected with a first radio access network (RAN);
selecting, by the UE, a second RAN based on the LWA assistance configuration; and
aggregating data traffic at least between the first RAN and the second RAN, by the UE, wherein the first RAN is LTE, the second RAN is WLAN, and wherein the LWA assistance configuration includes at least one information element comprising;
a list of LWA-enabled WLAN access points (APs), a list of LWA-enabled WLAN APs with the type of LWA access supported, a list of prioritized LWA-enabled WLAN APs.

Abstract
Apparatus and methods are provided for selection and data aggregation for the LWA. In one novel aspect, the UE connected with a first RAN receives a LWA assistance configuration and selects a second RAN based on the LWA assistance configuration. The UE aggregates data traffic from the first RAN and the selected second RAN. In one embodiment, the information request-and-response procedure is used, which allows the first RAN to query the UE about its second RAN association status. In another embodiment, the selection request-and-response procedure is used, which allows the first RAN to exercise some control over which base station of the second RAN is selected by the UE and for the UE to send relevant information about its second RAN connectivity to the first RAN. In another novel aspect, the UE selects a DRB based on the LWA DRB configuration through either a NAS procedure or an operator configuration.

10. A method, comprising:
-
obtaining, by a user equipment (UE), an LTE-WLAN aggregation (LWA) dedicated radio bearer (DRB) configuration by a user equipment (UE) in a wireless network wherein the UE is connected with a first radio access network (RAN); selecting, by the UE, a second RAN, wherein the UE aggregates data traffic between at least the first RAN and the second RAN; and informing, by the UE, the first RAN of a bearer-eligibility for a LWA access based on the LWA DRB configuration, wherein the LWA DRB configuration is obtained through an access stratum (AS) layer of the wireless network. - View Dependent Claims (11, 12, 13)
