METHOD AND APPARATUS FOR MULTI-RAT TRANSMISSION
First Claim
1. A method for mobility management in a mobile network having a first radio access technology node and a second radio access technology node, the first radio access technology node and the second radio access technology node communicating over a backhaul interface, the method comprising:
- detecting, by the first radio access technology node, that a handover for a user equipment to a new node is required;
providing, by the first radio access technology node, handover information to the second radio access technology node over the backhaul interface; and
performing, by the first radio access technology node, the handover of the user equipment to the new node.

Abstract
A method and apparatus for mobility management, load management, sharing management and configuration update and setup in a mobile network having a first radio access technology node and a second radio access technology node, the first radio access technology node and the second radio access technology node communicating over a backhaul interface. In one aspect the method detects, at the first radio access technology node, that a handover for a user equipment to a new node is required; provides, from the first radio access technology node, handover information to the second radio access technology node over the backhaul interface; and performs the handover of the user equipment from the first radio access technology node to the new node.

8. A method at a network node targeted for a handover of a user equipment from a first radio access technology node, the user equipment communicating with both the first radio access technology node and with a second radio access technology node, the method comprising:
-
receiving, from the first radio access technology node, a handover request message including context information for the user equipment; and establishing a backhaul interface with the second radio access technology node; and connecting to the user equipment. - View Dependent Claims (9, 10, 11, 12, 13)

14. A method for mobility management in a mobile network having a first radio access technology node and a second radio access technology node each communicating with a user equipment, the first radio access technology node and the second radio access technology node communicating over a backhaul interface, the method comprising:
-
receiving, at the second radio access technology node, handover information indicating the user equipment is being handed over to a new network node; and establishing, from the second radio access technology node, a backhaul interface to the new network node. - View Dependent Claims (15)

16. A method for mobility management in a mobile network having a first radio access technology node and a second radio access technology node, the first radio access technology node and the second radio access technology node communicating over a backhaul interface, the method comprising:
-
detecting, by the first radio access technology node, that a handover for a user equipment is required; providing, by the first radio access technology node, a handover request to the second radio access technology node over the backhaul interface; and sending, by the first radio access technology node, a handover command to the user equipment. - View Dependent Claims (17, 18)

19. A method at a first node of a first radio access technology for communicating data received from a second node having a second radio access technology to a user equipment, the method comprising:
-
receiving the data, the data being a protocol layer packet of the second radio access technology; adding a sequence number to the protocol layer packet; adding a multi-radio access technology header to the protocol layer packet; and forwarding the packet to the user equipment. - View Dependent Claims (20, 21, 22, 23)
