Question
Direct Tunnel in Rel 7 is the connection between…
- a. GGSN - RNC
- b. SGSN - RNC
- c. MSC - SGSN
- d. MSC - GGSN
Solution
The Direct Tunnel in Rel 7 is the connection between SGSN - RNC. So, the correct answer is b. SGSN - RNC.
Here's a step-by-step explanation:
-
In the context of mobile communication, Rel 7 refers to Release 7, a set of specifications for 3G networks issued by the 3rd Generation Partnership Project (3GPP).
-
The Direct Tunnel is a feature introduced in Release 7 to improve data transfer efficiency.
-
The Direct Tunnel establishes a direct path between the Serving GPRS Support Node (SGSN) and the Radio Network Controller (RNC), bypassing the Gateway GPRS Support Node (GGSN).
-
This direct connection reduces latency and increases speed, as data no longer needs to pass through the GGSN.
-
Therefore, the Direct Tunnel in Rel 7 is the connection between the SGSN and
