What is cell barred in 5G?

What is cell barred in 5G?

cellBarred (1-bit): Carried within MIB. This field indicates whether or not UEs in the cell are allowed to access the cell; ‘barred’ indicates, the UEs are not allowed to access the cell.

What is SMF and UPF in 5G?

The 5G Session Management Function (SMF) is a fundamental element of the 5G Service-Based Architecture (SBA). The SMF is primarily responsible for interacting with the decoupled data plane, creating updating and removing Protocol Data Unit (PDU) sessions and managing session context with the User Plane Function (UPF).

What is SGW and PGW in 5G?

SGW (Serving Gateway) – is the boundary between E-UTRAN and EPC. SGW transfers data from the eNodeB to the PGW using the S1-U (in communication with the eNodeB) and S5 / S8 (in communication with the PGW) interfaces.

What is N26 in 5G?

N26 is an inter-CN interface between AMF and MME in order to enable interworking between the 5G core and EPC. Support of N26 interface in the network is optional. Interworking procedures using N26 interface enable the exchange of MM and SM states between the source and target networks.

What is Nef in 5G?

Network Exposure Function is one of the capabilities that is natively built into the 5G network, Applications can subscribe to certain changes in the network and command the network to exploit its programmable capabilities providing new innovative services for the end-users.

What is a Access class?

Access class (AC) information for a UE is stored in the USIM(your UE SIM card). Even among those 15 categories there are ordinary and Special Categories defined. These access classes help the UE to delay or allow services such as mobile originating signaling, mobile originating data , voice service etc.

What is Access Class Barring?

Access Class Barring (ACB) is a congestion control scheme designed for limiting the number of simultaneous access attempts from certain UEs. The main purpose of ACB is to redistribute the access requests of UEs through time to reduce the number of access requests per RAO.

What is GGSN and PGW?

P-GW—In 2G and 3G networks, the node that handled all user packets to and from the user equipment is called the GGSN. In the LTE architecture, this is the Packet Gateway (P-GW) or sometimes seen as the Packet Data Network Gateway (PDN-GW).

What is the use of SGW?

SGW (Serving Gateway):The main function of the Serving Gateway is routing and forwarding of user data packets. It is also responsible for inter-eNB handovers in the U-plane and provides mobility between LTE and other types of networks, such as between 2G/3G and P-GW.

What is S1 and N1 mode in 5G?

N1 Mode and S1 Mode Defination N1 mode: In N1 mode UE is allowed to access to 5G core network via the 5G access network. S1 mode: with S1 Mode, there is a single UE’s usage setting at the UE which applies to both 5GS and EPS.

What is N2 handover in 5G?

N2 Handover can be Intra Frequency HO and Inter Frequency HO. Source and Target gNB can be connected two different UPFs. Re-Registration is required after Successful Handover if the Source gNB and Target gNB belong to different Tracking Area (TAC)

What is 3GPP NEF?

The Network Exposure Function (NEF) is a functional element that supports the following functionalities: Securely exposes network capabilities and events provided by 3GPP Network Functions to AF.

What is PCF in 5G?

5G Cloud Native Core, Policy Control Function Oracle Communications Cloud Native Core, Policy Control Function (PCF) helps operators to easily create and seamlessly deploy policies in a 5G network.

What is Access class in LTE?

What is the difference between access class and access group?

Access-group applies an ACL to an interface and the access-class applies the ACL to your vty access in this case. access-group is assigned on an interface and will filter data packets as they enter the interface or as they leave the interface (depending on whether the access-group is applied inbound or outbound).
