Radio base station, edge server, and methods therein
A RAN node ( 2 ) receives, from a core network node ( 6, 7, 8 ), a first identifier that is used by a service, an application, or an edge server ( 5 ) to identify a radio terminal ( 1 ) connected to the RAN node ( 2 ), and associates the first identifier with a second identifier that is used by the RAN node ( 2 ) to identify the radio terminal ( 1 ). Further, the RAN node ( 2 ) communicates with the edge server ( 5 ) using the first identifier. It is thus, for example, possible to allow an MEC server (or an MEC application hosted on the MEC server) and a radio access network (RAN) node to directly exchange therebetween a control message regarding a specific radio terminal.
1. A method performed by a radio base station, the method comprising:
receiving a Tunnel Endpoint Identifier (TEID) of a User Equipment (UE) from a core network node;
associating an Internet Protocol (IP) address of the UE with the TEID of the UE; and
in response to receiving a request message containing the IP address of the UE from a Mobile Edge Computing (MEC) server different from the core network node, transmitting to the MEC_server a response message containing radio access bearer information of the UE,
wherein the radio access bearer information comprises information on a Quality of Service Class Identifier (QCI) of the UE.
2. The method of claim 1 , wherein the radio access bearer information further comprises information on a Quality of Service (QoS) of the UE.
3. The method of claim 1 , wherein the radio base station is arranged in a radio access network.
4. A method performed by a Mobile Edge Computing (MEC) server, the method comprising:
sending a request message containing an Internet Protocol (IP) address of a User Equipment (UE) to a radio base station; and
receiving from the radio base station a response message containing radio access bearer information of the UE, wherein
the IP address of the UE is associated with a Tunnel Endpoint Identifier (TEID) of the UE by the radio base station, and
the radio access bearer information comprises information on a Quality of Service Class Identifier (QCI) of the UE, and wherein the TED of the UE is received by the radio base station from a core network node different from the MEC server.
5. The method of claim 4 , wherein the radio access bearer information further comprises information on a Quality of Service (QoS) of the UE.
6. The method of claim 4 , wherein the radio base station is arranged in a radio access network.
7. A radio base station comprising:
a controller configured to receive a Tunnel Endpoint Identifier (TED) of a User Equipment (UE) from a core network node and associate an Internet Protocol (IP) address of the UE with the TED of the UE; and
a transceiver configured to, in response to receiving a request message containing the IP address of the UE from a Mobile Edge Computing (MEC) server different from the core network node, transmit to the MEC server a response message containing a radio access bearer information of the UE,
wherein the radio access bearer information comprises information on a Quality of Service Class Identifier (QCI) of the UE.
8. The radio base station of claim 7 , wherein the radio access bearer information further comprises information on a Quality of Service (QoS) of the UE.
9. The radio base station of claim 7 , wherein the radio base station is arranged in a radio access network.
