Abstract
Embodiments of the present invention disclose a method for implementing a radio resource control protocol function, a macro base station, and a micro cell node. In the method, a macro base station configures control information and sends the control information to a micro cell node, so that the micro cell node forwards the control information to a user equipment. Therefore, the macro base station assists a micro cell node having no RRC function in completing generation and parsing of dedicated control information of the UE and cell common control information, so that a the user equipment can camp on or be handed over to the micro cell node.
Claims20
A method comprising:
- configuring, by a macro base station, first control information for a user equipment (UE), the first control information comprising at least a portion of total control information that is required by the UE to access a micro cell node, wherein the micro cell node has no radio resource control (RRC) functionality or has only a portion of simplified RRC functionality, and the micro cell node lacks an ability to provide access to UEs using an RRC function, and wherein the first control information is configured based on whether the micro cell node has no RRC functionality or has only the portion of simplified RRC functionality;
- and
- sending, by the macro base station, the first control information to the micro cell node, so that the first control information enables the UE to access the micro cell node.
A method comprising:
- receiving, by a micro cell node, first control information sent by a macro base station, the micro cell node having no radio resource control (RRC) functionality or has only a portion of simplified RRC functionality, and lacking capability of providing access to user equipments (UEs) using a RRC function, wherein the first control information comprises at least a portion of total control information that is required by a UE to access the micro cell node, and wherein the first control information comprises different information based on whether the micro cell node has no RRC functionality or has only the portion of simplified RRC functionality;
- and
- forwarding the first control information to the UE, the first control information enabling the UE to access the micro cell node.
A macro base station, wherein the macro base station comprises:
- a processor, configured to configure first control information, the first control information comprising at least a portion of total control information that is required by a user equipment (UE) to access a micro cell node, wherein the micro cell node has no radio resource control (RRC) functionality or has only a portion of simplified RRC functionality, and the micro cell node lacks an ability to provide access to UEs using a RRC function, and wherein the first control information is configured based on whether the micro cell node has no RRC functionality or has only the portion of simplified RRC functionality;
- and
- a transmitter, configured to send the first control information to the micro cell node, the first control information enabling the UE to access the micro cell node.
A micro cell node, wherein the micro cell node comprises:
- a receiver, configured to receive first control information sent by a macro base station, the micro cell node having no radio resource control (RRC) functionality or has only a portion of simplified RRC functionality, and lacking capability of providing access to user equipments (UEs) using a RRC function, wherein the first control information comprises at least a portion of total control information that is required by a UE to access the micro cell node, and wherein the first control information comprises different information based on whether the micro cell node has no RRC functionality or has only the portion of simplified RRC functions;
- and
- a processor, configured to forward the first control information to a UE, the first control information enabling the UE to access the micro cell node.
