4. The method of claim 1 , wherein the first message server querying a subscriber database to determine a voicemail system (VMS) to serve a subscriber identified by the MSISDN comprises, the first message server submitting a lightweight directory access protocol (LDAP) query to the subscriber database to acquire a hostname for the VMS.
5. The method of claim 1 , wherein the first message server querying the subscriber database to determine the VMS to serve the subscriber identified by the MSISDN comprises: the first message server querying the subscriber database to obtain a VM identification (VM_ID); and, wherein the first message server receiving from the subscriber database the IP address for the VMS is in response to the first message server directing a domain name server (DNS) query to a DNS to resolve the VM_ID to the IP address and the DNS sending the IP address to the first message server.
6. The method of claim 1 , wherein the first message server querying the subscriber database to determine the VMS to serve the subscriber identified by the MSISDN comprises: the first message server querying the subscriber database to obtain a VM identification (VM_ID); and, wherein the first message server receiving from the subscriber database the IP address for the VMS is in response to the first message server directing a query to a data table of the subscriber database to resolve the VM_ID to the IP address.
7. A system for provisioning a mobile device for visual voicemail (VVM) service in a wireless communications network, the system comprising:
a first message server comprising a memory and a processor, wherein the memory is configured to store instructions that, when executed by the processor, cause the processor to perform the steps of:
receiving a first message, the first message comprising a mobile subscriber integrated service digital network (MSISDN) number, wherein: the first message is generated by the mobile device automatically in response to a new subscriber identity module (SIM) being detected upon insertion into a SIM interface of the mobile device; and the first message is sent by the mobile device to a location register whereat the MSISDN number is appended to the first message prior to the location register forwarding the first message to the first message server;
querying a subscriber database to determine a voicemail system (VMS) to serve a subscriber identified by the MSISDN;
receiving from the subscriber database an Internet protocol (IP) address for the VMS;
directing a subscriber voicemail class of service (VM COS) query to the IP address to retrieve a VM COS for the subscriber from the VMS; and
in response to receiving the VM COS for the subscriber from the VMS, delivering the VM COS to a second message server for delivery to the mobile device.
8. The system of claim 7 , wherein the first message server is an unstructured supplementary service data (USSD) server and the first message is a USSD message.
9. The system of claim 7 , wherein in response to receiving the VM COS for the subscriber from the VMS, delivering the VM COS to a second message server for delivery to the mobile device comprises, delivering the VM COS to a short message service center (SMSC) for delivery to the mobile device via SMS.
10. The system of claim 7 , wherein querying the subscriber database to determine the VMS to serve the subscriber identified by the MSISDN comprises, submitting a lightweight directory access protocol (LDAP) query to the subscriber database to acquire a hostname for the VMS.
11. The system of claim 7 , wherein querying the subscriber database to determine the VMS to serve the subscriber identified by the MSISDN comprises: the first message server querying the subscriber database to obtain a VM identification (VM_ID); and, wherein receiving from the subscriber database the IP address for the VMS is in response to the first message server directing a domain name server (DNS) query to a DNS to resolve the VM_ID to the IP address and the DNS sending the IP address to the first message server.
12. The system of claim 7 , wherein querying the subscriber database to determine the VMS to serve the subscriber identified by the MSISDN comprises: querying the subscriber database to obtain a VM identification (VM_ID); and, wherein receiving from the subscriber database the IP address for the VMS is in response to the first message server directing a query to a data table of the subscriber database to resolve the VM_ID to the IP address.
13. A non-transitory computer-readable medium comprising computer-executable instructions that, when executed, perform the steps of:
receiving a first message, the first message comprising a mobile subscriber integrated service digital network (MSISDN) number, wherein: the first message is generated by the mobile device automatically in response to a new subscriber identity module (SIM) being detected upon insertion into a SIM interface of the mobile device; and the first message is sent by the mobile device to a location register whereat the MSISDN number is appended to the first message prior to the location register forwarding the first message to the first message server;
querying a subscriber database to determine a voicemail system (VMS) to serve a subscriber identified by the MSISDN;
receiving from the subscriber database an Internet protocol (IP) address for the VMS;
