Distinguishing Subscriber Network Attributes According to Different Number Segments
The SMS system supports number heads for the GSM, CDMA, and TDMA networks.
If the subscriber belongs to the non-target network (Subscriber attributes can be
distinguished by number segment), the SMS system distinguishes the subscriber
network type according to the configured number head of the subscriber, and adopts
corresponding scheduling strategy and coding scheme for the successful delivery of
the SM. For detailed scheduling strategy, refer to section Multidimensional Intelligent Scheduling.”
NP Function
The SMS system supports the NP function. For subscribers in the target network, the
system cannot distinguish from GSM subscribers, CDMA subscribers, and TDMA
subscribers, as well as subscribers of the local operator from those of other operators Because the subscriber can transfer between operators without changing its
MSISDN). The SMS system provides registration function for subscribers. The
attributes of registered subscribers contain information on subscriber network type,
which helps the SMS system distinguish from the GSM subscribers, CDMA subscribers, and TDMA subscribers. For unregistered subscribers, the SMS system regards them as the subscribers of other operators. The SMS system adopts different scheduling strategies and scheming codes according to the network types of subscribers for the successful delivery of the SMs. For subscribers belong to other operators, the SMS system forcibly forwards the SMs to a certain account, which is usually connected with another interworking gateway (not an infoX-SMS GW). The gateway then forwards the SMs to SMS systems of other operators. Meanwhile, the SMS system provides realtime registration interface, which is used to refresh subscriber information in the database.
Note:
Being different from the NP function of the SMS system for the GSM network, the SMS system for the CDMA, GSM and TDMA networks is connected with the NP Server. Instead, it distinguishes the subscriber attributes according to subscriber information in the subscriber list, and forcibly forwards SMs which are sent to subscribers of other operators to the interworking gateway. This function is applied in the current SMS system.
