The Interworking MSC of the SMSC, on receipt of the MAP mo-ForwardSM message, passes the SMS-PP [2] Application Protocol Data Unit (APDU) containing the text message to the actual Service Centre (SC) of the SMSC for storing, and subsequent "forwarding" (delivery) to the destination address and the SC returns an acknowledgement indicating ...
It is defined by the ETSI's GSM committee and 3GPP and is part of the 2G, 3G, 4G and 5G standards. [1] It is also known as Short Message Service-Cell Broadcast (SMS-CB or CB SMS). [2] [3] Unlike Short Message Service-Point to Point (SMS-PP), Cell Broadcast is a one-to-many geo-targeted and geo-fenced messaging service.
The connection remains open, allowing a two-way exchange of a sequence of data. This makes USSD faster than services that use SMS. [1] While GSM is being phased out in the 2020s with 2G and 3G technologies, USSD services can be supported over LTE, 5G, and IMS.
In 3G, the most prevalent technology was UMTS with CDMA-2000 in close contention. All radio access technologies have to solve the same problems: to divide the finite RF spectrum among multiple users as efficiently as possible. GSM uses TDMA and FDMA for user and cell separation. UMTS, IS-95 and CDMA-2000 use CDMA. WiMAX and LTE use OFDM.
An SMS center (SMSC) is responsible for handling the SMS operations of a wireless network. When an SMS message is sent from a mobile phone, it will first reach an SMS center. The SMS center then forwards the SMS message towards the destination. The main duty of an SMSC is to route SMS messages and regulate the process.

Instead of forwarding call traffic through to an operator's mobile switching center, OpenBTS delivers calls via SIP to a VOIP soft switch (such as FreeSWITCH or yate) or PBX (such as Asterisk). This VOIP switch or PBX software can be installed on the same computer used to run OpenBTS itself, forming a self-contained cellular network in a single ...
