PCI Conflict Detection And Optimization Method, Apparatus, And System

A control network element comprising:

• at least one processor;
• one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to perform operations comprising:
• receiving a physical cell identifier (PCI) conflict detection notification message for triggering the control network element to perform PCI conflict detection;
• determining that a PCI conflict exists in at least two cells;
• determining whether the at least two cells are managed by the control network element;
• in response to determining that the at least two cells are cells managed by the control network element, performing PCI optimization on PCI conflicted cells managed by the control network element, wherein the PCI conflicted cells comprise the at least two cells;
• and
• in response to determining that at least one of the at least two cells is not a cell managed by the control network element, sending a PCI optimization request message to a first management network element, wherein the PCI optimization request message requests the first management network element to perform PCI optimization.

A non-transitory, computer-readable medium storing one or more instructions executable by at least one processor to perform operations comprising:

• receiving, by a first control network element, a physical cell identifier (PCI) conflict detection notification message for triggering the first control network element to perform PCI conflict detection;
• determining, by the first control network element, that a PCI conflict exists in at least two cells;
• determining whether the at least two cells are managed by the first control network element;
• in response to determining that the at least two cells are cells managed by the first control network element, performing, by the first control network element, PCI optimization on PCI conflicted cells managed by the first control network element, wherein the PCI conflicted cells comprise the at least two cells;
• and
• in response to determining that at least one of the at least two cells is not a cell managed by the first control network element, sending, by the first control network element, a PCI optimization request message to a first management network element, wherein the PCI optimization request message requests the first management network element to perform PCI optimization.
