US 10,568,005 B2 · Method and system for X2-messaging in cloud radio access network (C-RAN)

Abstract

This disclosure relates generally to cloud radio access network (C-RAN), and more particularly to X2-messaging in the C-RAN. The method may include receiving, by a control unit in the CRAN, in the C-RAN, a request from a first virtual eNodeB (eNB) associated with a source eNodeB (eNB) to establish a X2 interface with each virtual eNB associated with a set of neighbor eNBs. A second virtual eNB associated with a target eNB may be selected from the virtual eNBs associated with the set of neighbor eNBs. A check may be made to determine whether the first virtual eNB and the second virtual eNB associated with the target eNB are co-located on same datacenter in the C-RAN. At least one X2 message may be transmitted between the first virtual eNB and the second virtual eNB that are co-located on the datacenter based on eNB information accessed from a shared storage.

A method of X2-messaging in a Cloud Radio Access Network (C-RAN), the method comprising:

receiving, by a control unit in the C-RAN, a request from a first virtual eNodeB (eNB) associated with a source eNodeB (eNB) to establish a X2 interface with each virtual eNB associated with a set of neighbor eNBs;
selecting, by the control unit, a second virtual eNB associated with a target eNB from the virtual eNBs associated with the set of neighbor eNBs;
determining, by the control unit, whether the first virtual eNB associated with the source eNB and the second virtual eNB associated with the target eNB are co-located and/or running on same datacenter in the C-RAN;
transmitting, by the control unit, at least one X2 message between the first virtual eNB and the second virtual eNB based on eNB information accessed from a shared storage when the first virtual eNB and the second virtual eNB are co-located on the datacenter;
and
performing at least one X2 interface function on at least one of the source eNB or the target eNB based on the at least one X2 message transmitted between the first virtual eNB and the second virtual eNB.

A Cloud Radio Access Network (C-RAN) comprising:

a plurality of virtual eNodeBs;
and
a control unit communicatively connected to each virtual eNodeB, wherein the control unit is to:
receive a request from a first virtual eNB associated with a source eNodeB (eNB) to establish a X2 interface with each virtual eNB associated with a set of neighbor eNBs;
select a second virtual eNB associated with a target eNB from the virtual eNBs associated with the set of neighbor eNBs;
determine whether a first virtual eNB associated with the source eNB and a second virtual eNB associated with the target eNB are co-located and/or running on same datacenter in the C-RAN;
transmit at least one X2 message between the first virtual eNB and the second virtual eNB based on eNB information accessed from a shared storage when the first virtual eNB and the second virtual eNB are co-located on the datacenter;
and
perform at least one X2 interface function on at least one of the source eNB or the target eNB based on the at least one X2 message transmitted between the first virtual eNB and the second virtual eNB.
