5G: How session and service continuity for an UE would be different in 5G compare to the LTE ?
Answers
The explosive growth of data-driven service has been the main driver for 3GPP evolutions in recent years. 5G is expected to provide considerably more flexibility for customization compared to earlier generations. New deployments are expected to serve huge amounts of mobile data traffic, thus requiring very efficient user plane path management.
One of the key features of data service is session and service continuity. It ensures uninterrupted service experience to the user regardless whether there is any change of UE (User Equipment) IP address or change in the core network anchor point.
4G LTE evolved packet system provides continuity of IP session by maintaining P-GW and UE's PDU session IP address regardless of UE mobility events. However, not all applications require guaranteed IP session continuity even if service continuity is needed. The 5G network provides more flexibility with another evolution by offering different types of session continuity depending on UE or service type.
To addresses various continuity requirements of different applications/services, 5G System architecture provides three Session and Service Continuity (SSC) modes. Once an SSC mode is associated with a PDU Session then it does not change during the lifetime of the PDU Session. The 5G architecture allows applications to influence the selection of SSC modes as needed for required data service.
SSC mode determines how User Plan Function (UPF) of PDU session is allocated and managed during session lifetime. It anchors IP address similar to P-GW in LTE evolved packet core network.
5G technology
----------------------------------------------
Now, Currently we are using 4G technology from 2 years and now its time for 5G.
5G will come late in so many countries, But fact is that 5G will be faster than Imagination. 50X Faster than 4G.
----------------------------------------------------
What is G?
First time when there was a 2G then that G was meant by Giga Hertz, But when 3G came then from that time G means GENERATION. Currently, there is a 4th Generation of the internet and thats the reason we are currently having 4G internet connection.
---------------------------
Does 5G will support your phone?
This time not at all devices, But only some devices will be have compatability of 5G internet connection. It is because 5G has works on very diffrent waves and diffrent GHz and 5G technology works on only some processors.
------------------------
How 5G works?
5G internet will be totally based on wirelesly and 5G will directly come to specific device with the help of sattellite. Yes, Thats the reality that 5G will be come to your phone directly by sattelite. 5G will be having a 5Ghz to 12.5GHz.
---------------------------
Processors supporting 5G!!
Here are some processors which will support 5G internet connection:
1) Snapdragon 845
2) Snapdragon 855
3) Exynos 9820
4) Exynos 9810
5) A11/A12 Apple processor
6) Snapdragon 700 series
7) Snapdragon 675
8) Snapdragon 835
9) Snapdragon 660
10) Exynos 7000 series

India - 5G
In India it is expected to launch 5G in October 2019. Also so many Indian Internet providers are working on sharing 5G technology with India.
Jio is working on its 7.5GHz Internet connection to the world. And Airtel is working as a 5G partners with the mobile companies.
----------------------------------------
5G internet speed?
we know that, 4G speed is 5mb/ps in India and 20 to 30 mb/ps in other countries. But 5G will have greater speed than 4G.
=======================
1G = 250kb/ps
2G = 1.2mb/ps
3G = 2mb/ps
4G = 5mb/ps
5G = ? => 10gb/ps (343MB/ps)
=======================
Yes! That's reality that 5G will have 10 GB/ps speed and so many mobile companies are trying to make it faster than it! 5G will have higher system capacity than other generations.
------------------------------------
Is 5G Harmful?
This is one of the most viral question about 5G internet. And the answer of this question is YES and NO. Because while 5G if that internet speed went more than 200MB/ps(Megabyte) then it can be harmful. But if it is under 200MB/ps then it is just like 4G. Youtube uses only 8Mb/ps internet. As well as this site(Brainly) Uses your internet in kb/ps. That's very good thing!!
--------------------------------
Xiaomi Mi Mix and Samsung galaxy S10 are the first smartphones which are launched with 5G supported.
Xiaomi has also shown the demo of First 5G video call live in MWC 2019. And It is said that 1080p video (654MB Video) was downloaded in 8 seconds
