Mobile CMPP protocol

CMPP (China Mobile Peer to Peer)

Chinese name: China Mobile Communication Internet Short Message Gateway Interface Protocol

Note: This is the enterprise specification of China Mobile Communications Corporation. The specifications describe the types and definitions of messages between different network elements (including ismg, GNS, and SP) in China Mobile Short Message Service.

Range:

The Specification defines the following three aspects:

(1) interface protocol between the information resource station entity and the Internet SMS gateway;

(2) interface protocols between Internet SMS gateways;

(3) interface protocol between the Internet SMS gateway and the gateway.

Applicable to various SP and ismg development vendors.

China Unicom SGIP Protocol

SGIP is the short message gateway system interface protocol of CEN.

Protocol description

This protocol is an interface protocol between SMG and SP, between SMG and GNS, and between SMG and SMG, referred to as SGIP.

By applying the SGIP protocol, the SP can be connected to SMG to achieve one-point access and full-network services for the SP application. The SMG can implement routing and forwarding of messages between different SMG through the SGIP protocol. SMG can also communicate with GNS through this Protocol to synchronize route tables between SMG and gns.

Applicability

This agreement applies to SP vendors and SMG developers.

Numbers can be expanded at will

Support China Unicom upstream and downstream

Supports text messages with a length of 300 characters

Provides secondary development interfaces.

China Telecom smgp Protocol

Smgp Protocol

Smgp (Short Message Gateway Protocol)

Definition

The smgp protocol is an interface protocol for short message transmission between smgw and other network elements (except SMC.

Non-SMC meta-devices send messages to or receive short messages from smgw. These non-SMC meta-devices are called

Esme.

Communication Method

Smgw and Esme have two Connection Methods: persistent connection and short connection. The so-called persistent connection refers

Multiple data packets can be sent continuously over TCP connections. If no data packet is sent during TCP connection persistence

Both parties send a link detection package to maintain this connection. A short connection is a TCP connection established when both parties have data interaction.

After the data is sent, the TCP connection is closed, that is, only one smgp message is sent each time.
