Abstract
Systems, methods, and processing nodes for communicating with a wireless device via at least two access nodes include receiving, at a gateway node, data addressed to a first network address of the wireless device, transmitting, via a donor access node, a first portion of the data within a first bearer addressed to a second network address of the wireless device, and transmitting, via a relay access node wirelessly coupled to the donor access node, a second portion of the data within a second bearer addressed to a third network address of the wireless device.
Claims18
A method for communicating with a wireless device via at least two access nodes, the method comprising:
- generating, at a controller node, a first network address and a second network address for the wireless device;
- generating, at the controller node, a mapping of the first network address and the second network address to a first and second bearer;
- forwarding the mapping and addresses to a gateway node;
- receiving, at the gateway node, the mapping and data addressed to the wireless device;
- splitting, at the gateway node, the data into a first data portion addressed to the first network address and a second data portion addressed to the second network address;
- transmitting, via the gateway node, the first data portion with the first bearer and the second data portion within the second bearer;
- receiving, at a donor access node, the first data portion via the first bearer addressed to the first network address of the wireless device;
- receiving, at a relay access node wirelessly coupled to the donor access node, the second data portion via the second bearer addressed to the second network address of the wireless device;
- and
- receiving, at the wireless device, the first and second data portions, wherein the wireless device is wirelessly coupled to both the donor access node and the relay access node.
A system for communicating with a wireless device via at least two access nodes, the system comprising:
- a donor access node configured to provide a first radio air interface to which a wireless device is attached;
- a relay access node configured to attach to the first radio air interface and to provide a second radio air interface to which the wireless device is further attached;
- a controller node communicably coupled to the donor access node, the controller node being configured to:
- determine that the wireless device is attached to both the donor access node and the relay access node;
- generate at least two addresses for the wireless device;
- generate a mapping of each of the at least two addresses to a corresponding bearer;
- and
- forward the mapping to one or more gateway nodes communicably coupled to the controller node;
- and
- a first gateway node communicably coupled to the controller node and being configured to:
- receive the mapping from the controller node;
- split a data packet addressed to the wireless device into a first data portion addressed to a first address of said at least two addresses and a second data portion addressed to a second address of said at least two addresses;
- transmit the first data portion to the donor access node using a first corresponding bearer mapped to the first address;
- and
- transmit the second data portion to the relay access node using a second corresponding bearer mapped to the second address;
- wherein each of the donor access node and the relay access node respectively forward the first and second data portions to the first and second addresses of the wireless device.
A processing node for communicating with a wireless device via at least two access nodes, comprising:
- a processor configured to:
- divide a data packet addressed to a wireless device into a first portion and a second portion;
- instruct, via a gateway node, a first access node to transmit the first portion to a first address associated with the wireless device;
- and
- instruct, via the gateway node, a second access node to transmit the second portion to a second address associated with the wireless device,
- wherein the second access node is in wireless communication with the first access node, and
- wherein the second access node receives the second portion from the first access node prior to forwarding the second portion to the wireless device.
