METHODS AND APPARATUS FOR ENABLING LOAD STEERING IN HETEROGENEOUS RADIO ACCESS NETWORKS

摘要

According to a first aspect there is provided a method of enabling load steering between a 3rd Generation Partnership Project (3GPP) Radio Access Network (RAN) and a Wi-Fi RAN. The method comprises, at a server, generating overlap information associating one or more cells of the 3GPP RAN with one or more Access Points (AP) of the Wi-Fi RAN, wherein a cell of the 3GPP RAN is associated with an AP of the Wi-Fi RAN if it is determined that the cell overlaps with an area covered by the AP. The server then determines an off-load schedule for a cell of the 3GPP RAN, the off-load schedule indicating when an overlapping AP of the Wi-Fi RAN can reject an attempt by a user terminal to attach to the AP of the Wi-Fi RAN, and sends the off-load schedule to the Wi-Fi RAN.

1. A method of enabling load steering between a 3rd Generation Partnership Project (3GPP) Radio Access Network (RAN) and a Wi-Fi RAN, the method comprising, at a server:
generating overlap information associating one or more cells of the 3GPP RAN with one or more Access Points, (AP) of the Wi-Fi RAN, wherein a cell of the 3GPP RAN is associated with an AP of the Wi-Fi RAN if it is determined that the cell overlaps with an area covered by the AP; determining an off-load schedule for a cell of the 3GPP RAN, the off-load schedule indicating when an overlapping AP of the Wi-Fi RAN can reject an attempt by a user terminal to attach to the AP of the Wi-Fi RAN; and sending the off-load schedule to the Wi-Fi RAN.
