Samsung patents faster 6G network setup by streamlining control signals
Samsung has filed a patent for a method to reduce delay in 6G wireless networks by simplifying how control messages are routed. The system sends routing information directly to the user's device, allowing it to communicate with specific network functions without extra steps. This aims to make the connection between the phone and the network more efficient.
In the filing’s own words
The present disclosure relates to a 6G communication system for supporting a higher data transmission rate. According to various embodiments of the present disclosure, provided is a method for operating a radio access network (RAN) comprising a distributed unit (DU) and a centralized unit (CU), the DU comprising a radio link control (RLC) and the CU comprising a radio resource control (RRC), and the method comprises the steps of: establishing an RRC connection with a user equipment (UE); transmitting, to an access mobility function (AMF), a non-access stratum (NAS) connection establishment request message including information about the UE; receiving, from the AMF, initial configuration information including routing information about network functions (NFs) corresponding to the UE, the NFs comprising the AMF, a session management function (SMF), and a policy control function (PCF); transmitting, to the UE, RRC connection re-configuration information including the routing information about the NFs corresponding to the UE; receiving, through the DU, a control message including address information about one of the NFs from the UE; and transmitting the control message to the NF.
What exactly they claim (claim 1)
1. An operating method of a radio access network (RAN) comprising a distributed unit (DU) and a centralized unit (CU) in a wireless communication system, the DU comprising a radio link control (RLC) and the CU comprising a radio resource control (RRC), the method comprising: establishing an RRC connection with a user equipment (UE); transmitting a non-access stratum (NAS) connection establishment request message comprising information about the UE to an access mobility function (AMF); receiving initial configuration information comprising routing information about network functions (NFs) corresponding to the UE from the AMF, the NFs comprising the AMF, a session management function (SMF), and a policy control function (PCF); transmitting RRC connection reconfiguration information comprising the routing information about the NFs corresponding to the UE to the UE; receiving a control message comprising address information about one NF among the NFs from the UE through the DU; and transmitting the control message to the NF.
