Automated addition and deletion of frequency relations in wireless communication networks

A system for automatically adding and deleting frequency relations in cells of a wireless communication network comprising:

• the wireless communication network including a radio access network (RAN);
• a self-optimizing network (SON) operated by a computer system in communication with the RAN, the computer system including a processor, a memory, and an input-output circuit, the processor being configured according to computer-executable instructions for adding and deleting frequency relations of the cells in the wireless communication network by:
• providing a first database storing a first list of frequencies broadcasted from a cell, wherein the first list further comprises neighboring co-site cells of the cell, and neighboring cells surrounding the cell;
• providing a second database storing defined frequency relations for the cell;
• providing frequencies corresponding to the defined frequency relations to provide a second list of frequencies, wherein the frequencies of the second list being frequencies available for handover to a user equipment in the cell;
• determining if the second list is missing any of the frequencies of the first list;
• if the determining is positive, processing a request to add frequency relations corresponding to the missing frequencies to the defined frequency relations of the cell in the second database in a same frequency relation updating session;
• determining if the second list includes extra frequencies;
• and
• if the determining is positive, processing a request to delete frequency relations corresponding to the extra frequencies from the defined frequency relations of the cell in the second database in the same frequency relation updating session.

A computer-implemented method for automatically adding or deleting frequency relations in cells of a wireless communication network comprising:

• providing a first database storing a first list of frequencies broadcasted from a cell, wherein the first list further comprises neighboring co-site cells of the cell, and neighboring cells surrounding the cell;
• providing a second database storing defined frequency relations for the cell;
• providing frequencies corresponding to the defined frequency relations to provide a second list of frequencies, wherein the frequencies of the second list being frequencies available for handover to a user equipment in the cell;
• determining if the second list is missing any of the frequencies of the first list;
• if the determining is positive, further determining if any of the missing frequencies are restricted from being added to the defined frequency relations of the cell;
• adding frequency relations corresponding to the missing frequencies to the defined frequency relations of the cell for each of the missing frequencies that are not restricted from being added to the defined frequency relations of the cell;
• determining if the second list includes extra frequencies, wherein the extra frequencies are protected from being deleted from the defined frequency relations of the cell;
• and
• if the determining is positive, deleting frequency relations corresponding to the extra frequencies from the defined frequency relations of the cell for each of the extra frequencies that are not protected from being deleted from the defined frequency relations of the cell.
