Cell Broadcast Service or Public warning system is part of 5G cell broadcast mechanism. Cell Broadcast Centre Function(CBCF), is generic broadcast centre responsible for all kind of broadcast messages including paid advertisement. Public Warning System(PWS) is specific to public warning related broadcast messages like Earthquake, Tsunami etc. Both the entities can Write/Replace/Cancel broadcast messages to ..read more

The concept of QoS in 5G is flow based. Packets are classified and marked using QFI (QoS Flow Identifier). The 5G QoS flows are mapped in the AN (Access Network) to DRBs (Data Radio Bearers) unlike 4G LTE where mapping is one to one between EPC and radio bearers. It supports following QoS flow types.  ..read more

Introduction In 5G in order to protect UE permanent Identity (SUPI- Subscription Permanent Identifier )  UE never transmit SUPI as it is. UE conceal(encrypt) SUPI using encryption scheme to create SUCI(Subscription Concealed Identifier), before sending it to core network. Concealing can be done in USIM or ME(Mobile Equipment) depending on the indication configured in USIM ..read more

Introduction In 5G network communication infrastructure is not just confined to mobile voice/text communication, it is now segregated and very diversified to different services like Industrial IoT, Smart home domestic IoT, Low latency Medical communication, high bandwidth mobile broadband etc. And each of these services require different data behavior and QoS from network infrastructure. In ..read more

1.1     Emergency Services FallBack ES-FB 1.1.1     Introduction Service Request for emergency: This solution is new in 5GS, i.e., there is no equivalent in 4G. The UE uses service-request for emergency towards AMF if support for this feature has been indicated by the AMF. If receiving the service request for emergency, the AMF interacts with gNB … The post Emergency Services(E911) FallBack procedures in 5G appeared first on 5G Resource Center Blogs ..read more

1.1     Introduction Voice over NR with EPS Fallback includes an additional mobility trigger by which the UE falls back from NG-RAN to LTE during call establishment. This may be needed, e.g., in case not all feature for voice over NR are implemented in the UE or in case of temporary lack of radio resources in … The post EPS Fallback Voice in 5G appeared first on 5G Resource Center Blogs ..read more

The 5G QoS flows are mapped in the AN (Access Network) to DRBs (Data Radio Bearers) unlike 4G LTE where mapping is one to one between EPC and radio bearers. It supports following QoS flow types.  GBR QoS flow, requires guaranteed flow bit rate. Non-GBR QoS flow, does not require guaranteed flow bit rate. Delay Critical  QoS flow, For Mission Critical  guaranteed flow bit rate. The 5G QoS flows are mapped in the AN (Access Network) to DRBs (Data Radio Bearers) unlike 4G LTE where m ..read more
