Method and apparatus for configuring radio bearer

A method for configuring a radio bearer applied to a target distributed unit, wherein the target distributed unit is one of at least two distributed units connecting to a central unit, and the method comprises:

• receiving protocol partitioning information for the radio bearer to be configured, wherein the protocol partitioning information is sent by the central unit and indicates an assignment of each protocol layer of a radio-side protocol stack between the central unit and the target distributed unit, and the radio-side protocol stack is a radio network protocol stack corresponding to the radio bearer on a radio access network side;
• configuring a first protocol stack according to the protocol partitioning information, wherein the first protocol stack comprises first protocol layers assigned to the target distributed unit in the radio-side protocol stack;
• and
• sending configuration information of the first protocol stack to the central unit, such that the central unit configures a second protocol stack according to the configuration information of the first protocol stack, wherein the second protocol stack comprises second protocol layers assigned to the central unit in the radio-side protocol stack.

An apparatus for configuring a radio bearer applied to a central unit connecting to at least two distributed units, comprising:

• a processor;
• a memory configured to store an instruction executable by the processor;
• wherein the processor is configured to:
• send protocol partitioning information for the radio bearer to be configured to a target distributed unit, wherein the protocol partitioning information indicates an assignment of each protocol layer of a radio-side protocol stack between the central unit and the target distributed unit, the radio-side protocol stack is a radio network protocol stack corresponding to the radio bearer on a radio access network side, and the target distributed unit is one of the at least two distributed units;
• receive configuration information of a first protocol stack sent by the target distributed unit, wherein the first protocol stack is configured by the target distributed unit according to the protocol partitioning information, and the first protocol stack comprises first protocol layers assigned to the target distributed unit in the radio-side protocol stack;
• and
• configure a second protocol stack according to the configuration information of the first protocol stack, wherein the second protocol stack comprises second protocol layers assigned to the central unit in the radio-side protocol stack.
