Abstract
A method, network node and UE device (115) for wireless access control and load balancing among various access nodes (105, 110) in a radio access network that contains both base stations (105) and relay notes (110). A wireless UE device (115) receives a message containing at least one of the respective loads for a group of access nodes and weighting factors for possible connections. The device determines a preferred access node (325, 425, 525) using at least one of the respective loads and weighting factors and attaches to the preferred access node.
Claims20
A wireless user equipment (UE) device comprising:
- a processor operably connected to a communication subsystem and to a memory containing instructions that when executed by the processor, perform the actions of:
- receiving a message from a base station in a wide area cellular network (WACN), the message comprising weighting factors for a plurality of possible connections to a plurality of access nodes, the plurality of access nodes comprising the base station and at least one relay node, the weighting factors supporting load balancing between the base station and the at least one relay node;
- determining a preferred access node using the weighting factors in order to maximize a number of UE devices the network is able to serve;
- and
- attaching to the preferred access node such that wireless communication via the WACN is facilitated.
A method operable on a wireless user equipment (UE) device, the method comprising:
- receiving a message from a base station in a wide area cellular network (WACN), the message comprising weighting factors for a plurality of possible connections to a plurality of access nodes, the plurality of access nodes comprising the base station and at least one relay node, the weighting factors supporting load balancing between the base station and the at least one relay node;
- determining a preferred access node using the weighting factors in order to maximize a number of UE devices the network is able to serve;
- and
- attaching to the preferred access node such that wireless communication via the WACN is facilitated.
A computer program product stored on a non-transitory computer-readable media and operable for execution on a wireless user equipment (UE) device, the computer program product comprising:
- instructions for receiving a message from a base station in a wide area cellular network (WACN), the message comprising weighting factors for a plurality of possible connections to a plurality of access nodes, the plurality of access nodes comprising the base station and at least one relay node, the weighting factors supporting load balancing between the base station and the at least one relay node;
- instructions for determining a preferred access node using the weighting factors in order to maximize a number of UE devices the network is able to serve;
- and
- instructions for attaching to the preferred access node such that wireless communication via the WACN is facilitated.
