Method and device for load balance

A method for load balancing, comprising:

• in response to a network edge node of an access network receiving a message including information indicating that a user equipment intends to access a network, causing the network edge node to enter a waiting state;
• and
• in response to the network edge node receiving during the waiting state, from a device, a message indicating that the network edge node is requested to serve the user equipment, transmitting a message to the user equipment, through the network edge node, indicating that the user equipment is served by the network edge node.

A device for load balancing, comprising:

• a selecting module, configured to select, when a message including information indicating that a user equipment intends to access a network is received, a network edge node from the network edge node pool, the selected network edge node having a capacity of bearing a load to serve the user equipment, wherein the selecting is based on one or more of a load state and a fault state of each network edge node in a network edge node pool of an access network;
• and
• a sending module, configured to send a message for indicating the selected network edge node to serve the user equipment to the selected network edge node.

A device for load balancing, comprising:

• an indicating module, configured to indicate to a network edge node, when the network edge node of an access network receives a message including information indicating that a user equipment intends to access a network, to enter a waiting state;
• and
• an informing module, configured to inform the user equipment, in response to the network edge node receiving during the waiting state, from a device, a message indicating that the network edge node is requested to serve the user equipment, through the network edge node, that the user equipment is served by the network edge node.
