CDMA MAP Server

The CDMA MAP Server is a part of the SMSC. It converts the signaling between layers TCAP and CDMA MAP, and converts CDMA MAP signaling into messages of the internal format and forwards them to the SMCAPP. The CDMA MAP Server, as a client, connects with the CTI Server directly; or as the server, connects with the USAU directly; and as the superior level of the signaling access gateway, processes the CDMA MAP signaling. At the same time, the CDMA MAP Server, as the server, is connected with the SMCAPP, implementing the conversion between the CDMA MAP signaling and messages of the internal format.

Features of the CDMA MAP Server:

Serial No                   Function                                                                                                     

1	The SM signaling in the CDMA network
2	The signaling flow of CDMA MSs submitting SMs to the MAP Server, and forwarding the submitted SMs to the SMCAPP
3	The signaling flow of the SMCAPP delivering SMs in the CDMA network  to the MAP Server, and returning delivery results to the SMCAPP
4	The signaling flow the HLR sending the Alert_SC message to the SMCAPP,  and supporting sending the message to the SMCAPP
5	The message forwarding flow among SMCs for the CDMA network
6	The delivery of multiple SMs in batches to increase the network efficiency
7	The monitoring of the running status of the system
8	The monitoring of the resources of the CDMA MAP Server
9	The query of the MS location
10	The monitoring of the message exchange between the MAP Server and  the SMCAPP, and between the MTI Server and the MAP Server
11	The E1/T1 signaling link
12	The SIGTRAN signaling
13	Multiple signaling points (SPs)
14	Supporting the interconnection of equipment for the GSM, CDMA, and TDMA networks at the headquarters of the China Unicom
15	MSC-located time zones
16	The sending of Alert_SC messages to several specified SMCs at the same time
