What are the interfaces used in GSM?
GSM Interfaces
| Interface | Network location |
|---|---|
| H interface | Between the MSC and the SMS Gateway. Used for transmitting SMS over the circuit switched network |
| I interface | Between the MSC and handsets in the network. Messages exchanged over the I interface are relayed transparently through the BSS |
Which interface is used from mobile to base station in GSM?
Um interface The “air” or radio interface standard that is used for exchanges between a mobile (ME) and a base station (BTS / BSC).
What are the different interfaces used in GSM with their required data rate and capability?
Um Interface Interface between Mobile Station (MS) and Base Station (BS) Two types of channels Physical Channel TDMA (Time Division Multiple Access) frame Logical Channel: These are transmitted on time slots of the physical channels. Payload transport Signalling Synchronization Channel assignment etc.
What is interface between MSC and HLR?
The C interface is a 3G interface between the MSC and HLR.
What does CDMA stand for?
Code Division Multiple Access
CDMA VS. GSM. CDMA stands for “Code Division Multiple Access.” GSM stands for “Global System for Mobiles.” They are 2 radio networks used by wireless carriers.
What is difference between GSM and CDMA?
GSM stands for Global System for Mobile communication, while CDMA stands for Code Division Multiple Access GSM uses FDMA (Frequency division multiple access) and TDMA (Time division multiple access). GSM supports transmitting data and voice both at once, but CDMA have not this feature.
What is Ater interface in GSM?
Ater is the physical connection between the BSC and the Transcoder.
What is GSM protocol?
The Global System for Mobile Communications (GSM) is a standard developed by the European Telecommunications Standards Institute (ETSI) to describe the protocols for second-generation (2G) digital cellular networks used by mobile devices such as mobile phones and tablets.
What are the protocols of GSM?
GSM – Protocol Stack
- MS Protocols. Based on the interface, the GSM signaling protocol is assembled into three general layers −
- MS to BTS Protocols. The RR layer is the lower layer that manages a link, both radio and fixed, between the MS and the MSC.
- BSC Protocols.
- MSC Protocols.
What is GSM interface C?
• C – The C interface is between the HLR and a GMSC or a SMS-G. MAP/C protocol over the C interface is used to. obtain the routing information required to complete the call.
What is interface between BSC and MSC?
In certain situations TRAU is located between the base station controller (BSC) and the mobile switching center (MSC) to gain an advantage of a more-compressed transmission between the BTS and the TRAU. Interface between the BTS and BSC is Abis.
