As a long-term partner Ericsson, Telia and Qualcomm Technologies have worked again to test a leading function in Telia's 5G commercial network, and push 5G innovation to new heights. This cooperation is a 5G Alliance, which cooperates with Telia and Ericsson, so that both sides provide better 5G networks for smartphone users and provide advanced and innovative 5G use cases for personal and enterprises. This new 5G independent network * function is called non-active state wireless system resource control (rrcinactive).

It can reduce the amount of signal written during the state conversion process, thereby significantly reduced delay and battery power consumption, meet many of the key requirements of many Internet of Things (IoT) and 5G, including remote device key control, enhanced mobile broadband and intelligent transmission. RRCINACTIVE is implemented by Ericsson's software and 5G independent network nodes and test equipment driven by the Snapdragon X60 modem and RF system. The two companies successfully demonstrate successful conversion between connection status and non-active states, rather than re-returning the device.

Convert to this innovative non-active state to reduce the signal written required during the state transition, greatly reduce the delay of end users. This test shows that the access delay is shortened to 1/3, which will bring huge changes to the user experience of the cloud game, etc. - In such applications, in order to achieve rapid multiplayer interaction, end-to-end delay must be controlled Within 20-30 milliseconds.

And the immersive VR game experience is more demanding for delay and reliability. Since this function is shortened, it is possible to reduce the non-active timer. This test also found that the battery power saving up to 30% is as high as 30% compared to the time when the function is not enabled.

While the screen and its related electronic devices are the most power-consuming components in mobile devices, it will be able to extend the battery life of 5G smartphone users after enabling this feature. Telia Chief Technology Stefanj?verBring said: "We are very happy to provide our customers with better quality new experience through close cooperation with Ericsson. We have achieved this industry through cooperation, and it is also the world's first function, and this technical achievement will use mobile network resources to more efficiently, provide effective solutions for some key needs.

Jennylindqvist, the person in charge of Ericsson Northern Europe and the China-European Market Region, said: "We are very happy to show this world's first innovative solution with Telia and Qualcomm, which will further improve the excellent mobile experience brought about by 5G. This is an important technical achievement of 5G technology to a new height. Wireless system resource control will continue to play a key role in the 5G network in the next few years.

"Qualcomm European Senior Vice President and Qualcomm Europe / Middle East President, ENRICOSALVATORI said:" We are proud to bring this key function to the market with Ericsson and Telia. For users, reduce delays, shorten content generation time, and extend battery life is equally important, and rrcinactive helps to meet these needs of users. "The development of non-active state functions is mainly driven by the continuous development of machine type communication (MTC) field, and this has become part of 3GPP standardization, and Ericsson has played a leading role in defining the functionality of this standard.

In most MTC scenarios, the amount of data exchange between wireless devices and network is generally very small, and its urgency is not worthwhile to consume a large amount of power to handle all signaling required for traditional idle to the connection conversion process. The current and future 5G uses will use a large number of equipment and this quantity is still increasing, so better connection, status, and mobile processing are key factors providing efficient support. * 5G Separate Network (5GSA) is the final architecture of 5G network, which can not only improve efficiency, but also help to develop new use cases.

Many 5G networks are deployed in a non-stand-alone network (NSA) mode, where the underlying 4G network layer supports the necessary signaling. 5GSA avoids this dependence on 4G. 5GSA can provide a better user experience by accelerating network connection time, simplifying mobile management and instant access, 5GSA.
