Apparatus and method for supporting operator-specific service in wireless access network
A method in an apparatus configured to use an interface between a radio access network intelligent controller (RIC) and a node including a base station operates in a radio access network; comprises: generating first information associated with an RIC service; generating second information indicating a type of message to be used for transmitting the first information; and transmitting a message including the first information and the second information.
1 . A method for an apparatus configured to use an interface between a radio access network intelligent controller (RIC) and a E2 node including a base station in a radio access network, the method comprising:
generating information related with an RIC service;
generating value indicating a type of a message to be used for transmitting the information; and
transmitting an E2 message comprising the information and the value,
wherein,
in case that the value indicates a first type, the E2 message includes a predetermined information element fields included in a predefined message format,
in case that the value indicates a second type, the E2 message includes at least a part of the predetermined information element fields included in the predefined message format and at least one additional field in a message format defined by an operator,
wherein the value belongs to either a first ran e or a se d range and
wherein a value indicating the first type belongs to a first range comprising values indicating the predefined message format, and a value indicating the second type belongs to a second range comprising values indicating the message format defined by the operator.
2 . The method of claim 1 , wherein the type of the message is determined based on the RIC service related to the first information.
3 . The method of claim 1 , wherein the type of the message corresponds to a format of the first information.
4 . The method of claim 1 , wherein the predefined message format is defined in the standard.
5 . The method of claim 1 , wherein the E2 node including the base station is one of a digital unit (DU), a central unit (CU)-control plane (CP), and a CU-user plane (UP).
6 . A method for an apparatus configured to use an interface between a radio access network intelligent controller (RIC) and a E2 node including a base station in a radio access network, the method comprising:
receiving a message comprising information related to an RIC service;
identifying a type of the message, based on a value indicating the type of the message included in the message; and
acquiring the first information, based on the values
wherein,
in case that the value indicates a first type, the E2 message includes predetermined information element fields included in a predefined message format,
in case that the value indicates a second type, the E2 message includes at least a part of the predetermined information element fields included in the predefined message format and at least one additional field in a message format defined by an operator,
wherein the value belongs to either a first range or a second range, and
wherein a value indicating the first type belongs to a first range comprising values indicating the predefined message format, and a value indicating the second type belongs to a second range comprising values indicating the message format defined by the operator.
7 . The method of claim 6 , wherein the type of the message is determined based on the RIC service related to the first information.
8 . The method of claim 6 , wherein the type of the message corresponds to a format of the first information.
9 . The method of claim 6 , wherein the predefined message format is defined in the standard.
10 . The method of claim 6 , wherein the node including the base station is one of a digital unit (DU), a central unit (CU)-control plane (CP), and a CU-user plane (UP).
11 . An apparatus configured to use an interface between a radio access network intelligent controller (RIC) and a node including a base station in a radio access network, the apparatus comprising:
a transceiver; and
at least one processor, comprising processor circuitry, connected to the transceiver,
wherein the at least one processor is configured, individually and/or collectively, to control the apparatus to:
generate information related with an RIC service;
generate a value indicating a type of a message to be used for transmitting the first-information; and
transmit an E2 message comprising the first-information and the value,
wherein,
in case that the value indicates a first type, the E2 message includes a-predetermined information element fields included in a predefined message format,
in case that the value indicates a second type, the E2 message includes at least a part of the predetermined information element fields included in the predefined message format and at least one additional field in a message format defined by an operator,
wherein the value belongs to either a first range or a second range, and
wherein a value indicating the first type belongs to a first range comprising values indicating the predefined message format, and a value indicating the second type belongs to a second range comprising values indicating the message format defined by the operator.
12 . The apparatus of claim 11 , wherein the type of the message is determined based on the RIC service related to the first information.
13 . The apparatus of claim 11 , wherein the type of the message corresponds to a format of the first information.
14 . The apparatus of claim 11 , wherein the predefined message format is defined in the standard.
15 . The apparatus of claim 11 , wherein the node including the base station is one of a digital unit (DU), a central unit (CU)-control plane (CP), and a CU-user plane (UP).
16 . The method of claim 1 , wherein for the second type message the at least one additional field is defined by or configured specifically for an operator.
17 . The method of claim 6 , wherein for the second type message the at least one additional field is defined by or configured specifically for an operator.
18 . The apparatus of claim 11 , wherein for the second type message the at least one additional field is defined by or configured specifically for an operator.
