Abstract

Aspects relate to a Remote NodeB Relay that appears similar to a NodeB, a Radio Network Controller (RNC), and served mobile devices. Also provided is a Super-Light Router Relay that can provide better performance and QoS to served mobile devices while mitigating modifications to mobile devices, NodeBs, or interfaces between RNC and intermediary NodeBs. Aspects also relate to an Internet Protocol (IP) Relay that requires few, if any, modifications to mobile devices, NodeBs, or interfaces between RNC and intermediary NodeBs. Further, changes to an RNC and/or a core network can be mitigated though utilization of a strategic Relay Gateway.

Claims

1. A method performed by a relay for conveying relayed data in a wireless communications network, comprising:

employing a processor executing computer executable instructions stored on a computer readable storage medium to implement;

utilizing base station protocols to communicate as a base station to a served mobile device and mobile device protocols to communicate with an intermediary base station as a mobile device; and

carrying data transparently across at least one intermediary network element, wherein the relay comprises a relay self-backhaul internet protocol to carry the data to or from the mobile device and to or from a relay gateway transparently across the at least one intermediary network element.

2. A wireless communications apparatus, comprising:

a memory that retains instructions related to utilizing base station protocols to communicate as a base station to a served mobile device and mobile device protocols to communicate with an intermediary base station as a mobile device and carrying data transparently across at least one intermediary network element; and

a processor, coupled to the memory, configured to execute the instructions retained in the memory.

3. The wireless communications apparatus of claim 2, wherein a relay gateway is connected to a first support node, wherein the data to or from the mobile device is communicated to or from the relay gateway though a relay self-backhaul internet protocol, wherein the relay self-backhaul internet protocol carries the data to or from the mobile device and to or from the relay gateway transparently across the at least one intermediary network element.

4. The wireless communications apparatus of claim 3, wherein the relay gateway is connected to a second support node, wherein the data to or from the mobile device is communicated to or from a destination through the second support node.

5. A wireless communications apparatus that supports radio access technology interworking, comprising:

means for communicating with base station protocols to communicate as a base station to a served mobile device and with mobile device protocols to communicate with an intermediary base station as a mobile device; and

means for carrying data transparently across at least one intermediary network element.

6. The wireless communications apparatus of claim 5, wherein the wireless communications apparatus comprises a relay self-backhaul internet protocol that carries data to or from the mobile device and to or from a relay gateway transparently across the at least one intermediary network element.

7. A computer program product, comprising:

a computer readable storage medium comprising;

a first set of codes for causing a computer to communicate, as a base station, with base station protocols and as a mobile device, with mobile device protocols; and

a second set of codes for causing the computer to relay data transparently across at least one intermediary network element.

8. At least one processor, comprising:

a first module that communicates with base station protocols to communicate as a base station to a served mobile device and with mobile device protocols to communicate with an intermediary base station as a mobile device; and

a second module that carries data transparently across at least one intermediary network element.
