Abstract

Claims (61)

1 . A method for transmitting Mobile Station International Subscriber Directory Number (MSISDN) changes associated with telecommunication accounts in a telecommunications network, the method comprising:

receiving at a contact update server of the telecommunications network, from a unified data management (UDM), an indication of a change in MSISDN for an account;

retrieving, by the contact update server, contact information associated with the account from an XML document management server (XDMS),

wherein the contact information includes multiple contacts of the account, and wherein each contact is associated with an identifier;

generating, by the contact update server, a set of short messaging service (SMS) messages to each of the multiple contacts based on the associated identifiers,

wherein the SMS messages include information related to the MSISDN change;

transferring, by the contact update server, the set of SMS messages to a short message service center (SMSC) of the telecommunications network; and

delivering the SMS messages to each of the multiple contacts of the account by the SMSC.

2 . The method of claim 1 , wherein the SMS messages include a link to automatically update a MSISDN for a user associated with the account.

3 . The method of claim 1 , wherein the associated identifiers include a flag indicating a contact is a trusted contact, and wherein delivering the SMS messages to the multiple contacts of the account comprises delivering the SMS messages to a selected contact responsive to determining the selected contact is a trusted contact.

4 . The method of claim 1 , wherein delivering the SMS messages to each of the multiple contacts further comprises:

checking, by the SMSC, E.164 Number Mapping (ENUM) of each of the multiple contacts;

determining whether each of the multiple contacts is a local contact or an offnet contact; and

delivering, by the SMSC, the SMS messages to local contacts of the multiple contacts.

5 . The method of claim 4 , wherein the SMS messages are delivered, by the SMSC, to an external telecommunications network for offnet contacts.

6 . The method of claim 1 , wherein delivering the SMS messages to each of the multiple contacts further comprises:

determining whether a contact of the multiple contacts is available to receive the SMS messages;

delivering, by the SMSC, the SMS messages to available contacts; and

storing, by the SMSC, the SMS messages for a predetermined time for unavailable contacts.

7 . The method of claim 1 , wherein the SMS messages are system messages with an unidentified sender.

8 . A non-transitory, computer-readable storage medium comprising instructions recorded thereon, wherein the instructions when executed by at least one processor of a system, cause the system to:

receive, at a contact update server of a telecommunications network, from a unified data management (UDM), an indication of a telephone number change associated with an account in the telecommunications network;

retrieve, by the contact update server, contact information associated with the account from a virtual storage space of the telecommunications network, wherein the contact information includes multiple contacts of the account, and wherein each contact is associated with an identifier;

generate, by the contact update server, a set of short messaging service (SMS) messages to each of the multiple contacts based on the associated identifiers,

wherein the SMS messages include information related to the telephone number change;

transfer, by the contact update server, the set of SMS messages to a short message service center (SMSC) of the telecommunications network; and

deliver the SMS messages to each of the multiple contacts of the account via the SMSC.

9 . The non-transitory, computer-readable storage medium of claim 8 , wherein the SMS messages include a link to automatically update a telephone number for a user associated with the account.

10 . The non-transitory, computer-readable storage medium of claim 8 , wherein the associated identifiers include a flag indicating a contact is a trusted contact, and wherein delivering the SMS messages to the multiple contacts of the account comprises delivering the SMS messages to a selected contact responsive to determining the selected contact is a trusted contact.

11 . The non-transitory, computer-readable storage medium of claim 8 , wherein delivering the SMS messages to each of the multiple contacts further comprises:

checking, by the SMSC, E.164 Number Mapping (ENUM) of each of the multiple contacts;

determining whether each of the multiple contacts is a local contact or an offnet contact; and

delivering, by the SMSC, the SMS messages to local contacts of the multiple contacts.

12 . The non-transitory, computer-readable storage medium of claim 11 , wherein the SMS messages are delivered, by the SMSC, to an external telecommunications network for offnet contacts.

13 . The non-transitory, computer-readable storage medium of claim 8 , wherein delivering the SMS messages to each of the multiple contact further comprises:

determining whether a contact of the multiple contacts is available to receive the SMS messages;

delivering, by the SMSC, the SMS messages to available contacts; and

storing, by the SMSC, the SMS messages for a predetermined time for unavailable contacts.

14 . The non-transitory, computer-readable storage medium of claim 8 , wherein the SMS messages are system messages with an unidentified sender.

15 . A system comprising:

at least one hardware processor; and

at least one non-transitory memory storing instructions, which, when executed by the at least one hardware processor, cause the system to:

receive, at a contact update server of a telecommunications network, from a unified data management (UDM), an indication of a telephone number change associated with an account in the telecommunications network;

retrieve, by the contact update server, contact information associated with the account from a virtual storage space of the telecommunications network,

wherein the contact information includes multiple contacts of the account, and

wherein each contact is associated with an identifier;

generate, by the contact update server, a set of short messaging service (SMS) messages to each of the multiple contacts based on the associated identifiers,

wherein the SMS messages include information related to the telephone number change;

transfer, by the contact update server, the set of SMS messages to a short message service center (SMSC) of the telecommunications network; and

deliver the SMS messages to each of the multiple contacts of the account via the SMSC.

16 . The system of claim 15 , wherein the SMS messages include a link to automatically update a telephone number for a user associated with the account.

17 . The system of claim 15 , wherein the associated identifiers include a flag indicating a contact is a trusted contact, and wherein delivering the SMS messages to the multiple contacts of the account comprises delivering the SMS messages to a selected contact responsive to determining the selected contact is a trusted contact.

18 . The system of claim 15 , wherein delivering the SMS messages to each of the multiple contacts further comprises:

checking, by the SMSC, E.164 Number Mapping (ENUM) of each of the multiple contacts;

determining whether each of the multiple contacts is a local contact or an offnet contact; and

delivering, by the SMSC, the SMS messages to local contacts of the multiple contacts.

19 . The system of claim 18 , wherein the SMS messages are delivered, by the SMSC, to an external telecommunications network for offnet contacts.

20 . The system of claim 15 , wherein delivering the SMS messages to each of the multiple contact further comprises:

determining whether a contact of the multiple contacts is available to receive the SMS messages;

delivering, by the SMSC, the SMS messages to available contacts; and

storing, by the SMSC, the SMS messages for a predetermined time for unavailable contacts.
