Abstract
Abstract A method of maintaining directory data in a switching system network having plural switching systems and a centralized directory data management system in which local directory data is stored at each switching system, A copy of directory data of all the switching systems is stored at the management system. Directory data entries of the directory data stored at the management system are associated with groups of switching systems. Data entries associated within each group are downloaded to the switching systems designated in that group.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
115 words
A method of maintaining telephone directory data in a switching system network having plural switching systems and a centralized telephone directory data management system comprising the step of: (a) storing local telephone directory data in a memory contained in each of said switching systems, (b) storing a copy of said local telephone directory data of all of said switching systems in a memory contained in said management system, (c) associating telephone directory data entries of telephone directory data stored at said management system with designated groups of switching systems, and (d) downloading, from said management system, data entries associated with respective designated groups of switching systems to the switching systems in said respective designated groups.
Claim 2
Independent Claim
115 words
A method of maintaining telephone directory data in a switching system network having plural switching systems and a centralized telephone directory data management system comprising the step of: (a) storing local telephone directory data in a memory contained in each of said switching systems, (b) storing a copy of said local telephone directory data of all of said switching systems in a memory contained in said management system, (c) associating telephone directory data entries of telephone directory data stored at said management system with designated groups of switching systems, and (d) downloading, from said management system, data entries associated with respective designated groups of switching systems to the switching systems in said respective designated groups.
Claim 3
Dependent Claim
56 words
A method as defined in claim 1, wherein the downloading step further includes the step of determining whether a data entry has been associated with a group which contains a particular switching system, and refraining from downloading said data entry to the particular switching system if said data entry has previously been associated with said group.
Claim 4
Dependent Claim
42 words
A method as defined in claim 1, further comprising the step of over-writing each entry of telephone directory data stored at a particular switching system corresponding to downloaded data entries if the corresponding data entries already exist at the particular switching system.
Claim 5
Dependent Claim
93 words
A method as defined in claim 1, further comprising the steps of: (e) modifying a stored directory data entry at a switching system, (f) uploading the modified data entry to said management system, (g) modifying the copy of directory data at said management system, (h) determining which group is referenced by the modified data entry, (i) downloading, from said management system, the modified data entry to the switching systems in said referenced group, and (j) over-writing a corresponding data entry at each switching system in said referenced group with the modified data entry.
Claim 6
Dependent Claim
72 words
A method as defined in claim 1, further comprising the steps of: (e) modifying a stored directory data entry at said management system, (f) determining which group is referenced by the modified data entry, (g) downloading, from said management system, the modified data entry to the switching systems in said referenced group, and (h) over-writing a corresponding data entry at each switching system in said referenced group with the modified data entry.
Claim 7
Dependent Claim
133 words
A method as defined in claim 1, further comprising the steps of: (e) entering a directory data entry at a switching system, (f) uploading the directory data entry to said management system, (g) comparing the uploaded data entry with previously stored data entries, (h) if the event the data entry was not previously stored, associating it with an identity. Of a switching system from which it was uploaded, (i) if non-key data of a particular data entry is changed, downloading, from said management system, the particular data entry to the switching systems in a group with which the particular data entry is to be associated, and (j) over-writing a data entry at each switching system in which a corresponding data entry already exists, with the downloaded particular data entry and changed key data.
Claim 8
Dependent Claim
77 words
A method as defined in claim 1, further comprising the steps of: (e) deleting a directory data entry at the switching system, (f) uploading data entry delete data to the central management system, (g) determining which group the data entry to be deleted references, (h) deleting a corresponding directory data entry at the management system, and (i) if said corresponding directory data entry references a different group, reassigning the corresponding director data entry to said different group.
Claim 9
Dependent Claim
76 words
A method as defined in claim 1, further comprising the steps of: (e) receiving a directory data entry delete command at the management system, (f) determining which group the data entry to be deleted references, (g) downloading, from said management system, a delete directory data command to each of the switching systems in the group referenced by the entry to be deleted, and (h) deleting the directory data entry to be deleted at the management system.
Claim 10
Dependent Claim
151 words
A method as defined in claim 1, further comprising the steps of: (e) receiving a command at the management system to associate a directory data entry with a different group of switching systems than the group of switching systems with which the data entry had been associated, (f) comparing said different group of switching systems with the group with which the data entry had previously been associated, (g) modifying the group designation of the data entry at the management system to that of the different group, and (h) downloading, from said management system, a delete data entry command to the switching systems in the group to which the data entry previously belonged which are not included in said different group, and downloading, from said management system, the directory data entry to switching systems of said different group which were not included in the group to which the data entry previously belonged.
Claim 11
Dependent Claim
44 words
A method as defined in claim 1, further comprising the steps of: (e) adding an existing new switching system to a group of switching systems, and (f) downloading, from said management system, directory data entries that reference the group to the new switching system.
Claim 12
Dependent Claim
90 words
A method as defined in claim 1, further comprising the steps of: (e) creating identification of a new group of switching systems at the management system, (f) recording reference to the identification of the new group in a data entry at the management system, (g) determining whether any switching systems are referenced in the new group, and (h) downloading, from said management system, the data entry to any switching system which it has been determined was not referred to in any other group which contains reference to said data entry.
