Service data transmission method, first communications node, and base station

A method comprising:

• sending, by a base station, a first message including transmission carrier frequency configuration information of a first service type to a first communications node,
• wherein the transmission carrier frequency configuration information of the first service type comprises at least one first transmission carrier frequency identifier in the first message, the first transmission carrier frequency identifier indicating to the first communications node to determine, based on first service data and a first identifier in a second message received by the first communications node and based on the first transmission carrier frequency identifier in the first message, a first transmission carrier frequency used to transmit the first service data, the first identifier indicating that the first service data belongs to the first service type,
• wherein the first identifier includes a priority identifier that uniquely identifies the first service type,
• wherein the first service data and the first identifier including the priority identifier are received together in the second message as a single message at a protocol layer above an access stratum sent by a second communications node,
• wherein the first message and the second message are separate messages,
• wherein the priority identifier is one of a set of priority identifiers,
• wherein the set of priority identifiers correspond to the first service type, and
• wherein, when the transmission carrier frequency configuration information of the first service type comprises at least two first transmission carrier frequency identifiers, the first communications node selects based on resource load statuses of transmission carrier frequencies corresponding to the at least two first transmission carrier frequency identifiers, the first transmission carrier frequency corresponding to one of the at least two first transmission carrier frequency identifiers to transmit service data.

A first communications node comprising:

• at least one processor;
• and
• a non-transitory computer readable storage medium storing programming for execution by the at least one processor, the programming including instructions to cause the first communications node to perform operations including:
• receiving a first message including transmission carrier frequency configuration information of a first service type, wherein the transmission carrier frequency configuration information of the first service type comprises at least one first transmission carrier frequency identifier, and
• receiving a second message including first service data and a first identifier, wherein the first identifier indicates that the first service data belongs to the first service type, wherein the first identifier includes a priority identifier that uniquely identifies the first service type, wherein the first service data and the first identifier including the priority identifier are received together in the second message as a single message, wherein the first message and the second message are separate messages, wherein the priority identifier is one of a set of priority identifiers, and wherein the set of priority identifiers correspond to the first service type, wherein the receiving the second message including the first service data and the first identifier comprises:
• receiving the first service data and the first identifier in the second message at a protocol layer above an access stratum sent by a second communications node;
• determining, based on the first identifier in the second message and the first transmission carrier frequency identifier in the first message, a first transmission carrier frequency corresponding to the first transmission carrier frequency identifier, wherein, when the transmission carrier frequency configuration information of the first service type comprises at least two first transmission carrier frequency identifiers, the determining comprises:
• selecting, based on resource load statuses of transmission carrier frequencies corresponding to the at least two first transmission carrier frequency identifiers, the first transmission carrier frequency corresponding to one of the at least two first transmission carrier frequency identifiers to transmit service data;
• and
• transmitting the first service data on the first transmission carrier frequency.

A base station comprising:

• at least one processor;
• and
• a non-transitory computer readable storage medium storing programming for execution by the at least one processor, the programming including instructions to cause the base station to perform operations including:
• sending a first message including transmission carrier frequency configuration information of a first service type to a first communications node,
• wherein the transmission carrier frequency configuration information of the first service type comprises at least one first transmission carrier frequency identifier in the first message, the first transmission carrier frequency identifier indicating to the first communications node to determine, based on first service data and a first identifier in a second message received by the first communications node and based on the first transmission carrier frequency identifier in the first message, a first transmission carrier frequency used to transmit the first service data, the first identifier indicating that the first service data belongs to the first service type,
• wherein the first identifier includes a priority identifier that uniquely identifies the first service type,
• wherein the first service data and the first identifier including the priority identifier are received together in the second message as a single message at a protocol layer above an access stratum sent by a second communications node,
• wherein the first message and the second message are separate messages,
• wherein the priority identifier is one of a set of priority identifiers,
• wherein the set of priority identifiers correspond to the first service type, and
• wherein, when the transmission carrier frequency configuration information of the first service type comprises at least two first transmission carrier frequency identifiers, the first communications node selects based on resource load statuses of transmission carrier frequencies corresponding to the at least two first transmission carrier frequency identifiers, the first transmission carrier frequency corresponding to one of the at least two first transmission carrier frequency identifiers to transmit service data.
