Method and apparatus for coordination of self-optimization functions in a wireless network
First Claim
1. A network management device, comprising:
- an interface to communicate with a plurality of enhanced node Bs (eNodeBs), the interface being arranged to receive a request tochange a coverage or a capacity of an enhanced node B (eNodeB) of the plurality of eNodeBs;
one or more processors arranged todetermine whether to grant or deny the request based on a coordination policy and a self-optimizing network (SON) coordination state of the eNodeB of the plurality of eNodeBs, the SON coordination state being a state of SON functions, wherein the SON coordination state is one of;
an energy saving management (ESM) compensating state, wherein the ESM compensating state indicates that a respective eNodeB of the plurality of eNodeBs is already providing coverage for other eNodeBs of the plurality of eNodeBs that are switched off for energy-saving purposes by an ESM SON function,a cell outage compensation (COC) compensating state which indicates that a respective eNodeB of the plurality of eNodeBs is already providing coverage of a neighboring eNodeB that is in outage,a Coverage and Capacity Optimization (CCO) updating state that indicates that a respective eNodeB of the plurality of eNodeBs is updating the configuration parameters in a respective cell, anda SON None state that indicates that a respective eNodeB of the plurality of eNodeBs is not impacted by SON functions.

Abstract
A network management device and method for coordination of self-optimization functions in a wireless network. A network management device for coordination of self-optimization functions includes one or more processors and an interface. The interface communicates with a plurality of enhanced node Bs (eNodeBs). The interface is arranged to receive a request to change a coverage or a capacity of an enhanced node B (eNodeB). The interface is further arranged to transmit a query to the eNodeB to obtain a self-optimizing network (SON) coordination state of the eNodeB. The one or more processors are arranged to determine whether to grant or deny the request based on a coordination policy and the SON coordination state.

17. An enhanced node B (eNodeB) comprising:
-
an interface to communicate with a network management device, the interface arranged to, transmit a request to change a coverage or a capacity state, and receive a permission notification indicating whether the request to change the coverage or the capacity state has been granted or denied, and one or more processors arranged to, store a self-optimizing network (SON) coordination state in an associated memory, the SON coordination state being a state of SON functions, wherein the SON coordination state is one of; an energy saving management (ESM) compensating state, wherein the ESM compensating state indicates that a respective eNodeB of the plurality of eNodeBs is already providing coverage for other eNodeBs of the plurality of eNodeBs that are switched off for energy-saving purposes by an ESM SON function, a cell outage compensation (COC) compensating state which indicates that a respective eNodeB of the plurality of eNodeBs is already providing coverage of a neighboring eNodeB that is in outage, a Coverage and Capacity Optimization (CCO) updating state that indicates that a respective eNodeB of the plurality of eNodeBs is updating the configuration parameters in a respective cell, and a SON None state that indicates that a respective eNodeB of the plurality of eNodeBs is not impacted by SON functions, and change the coverage or capacity state based on the permission notification. - View Dependent Claims (18, 19)
