Problems solved by technology

[0004] In order to avoid inconsistent RRC connection configurations between the eNB and the UE, the eNB starts a timer after sending the RRC connection reconfiguration message to the UE. If the timer expires and does not receive a response message from the UE (RRC connection reconfiguration complete message or RRC connection re-establishment request message), the eNB will release the RRC connection of the UE, make the UE enter the RRC_IDLE (RRC idle) state, and then cause a call drop, which will not only increase the call drop rate but also affect the user experience

Embodiment 1

[0027] refer to figure 1 , which shows a flow chart of Embodiment 1 of a control method of the present invention, which may specifically include:

[0028] Step 101, sending a radio resource control RRC connection reconfiguration message to the user equipment, and starting a timer;

[0029] Step 102, when the timer expires, if it is determined that the RRC connection reconfiguration message is not valid for the user equipment, cancel the execution of the reconfiguration operation corresponding to the RRC connection reconfiguration message, and keep the The RRC connection state of the user equipment.

[0030] The embodiment of the present invention can be applied to a base station in an LTE system, and the base station may include: a base station provided with a large-scale antenna array, a sub-base station, and the like. The embodiment of the present invention is described by taking the LTE system as an example. It can be understood that the embodiment of the present inventio...

Embodiment 2

[0061] This embodiment explains in detail the specific execution process of each protocol layer of the base station when the RRC connection reconfiguration message is not sent successfully. refer to figure 2 , which shows a flow chart of Embodiment 2 of a control method of the present invention, which may specifically include:

[0062] Step 201, the RRC layer sends an RRC connection reconfiguration message to the packet data convergence protocol PDCP layer, and starts a timer;

[0063] Step 202, the PDCP layer encapsulates the RRC connection reconfiguration message into a PDCP PDU, and sends the PDCP PDU to the RLC layer;

[0064] Specifically, the PDCP layer adds a PDCP header and MACI to the SDU corresponding to the RRC connection reconfiguration message to obtain a PDCP PDU;

[0065] Step 203, the RLC layer encapsulates the RRC connection reconfiguration message into an RLC PDU, and sends the RLC PDU to the MAC layer;

[0066] Specifically, the RLC layer adds an RLC hea...

Embodiment 3

[0074] This embodiment details the specific execution process of each protocol layer of the base station when the RRC connection reconfiguration message is sent successfully. refer to image 3 , which shows a flow chart of Embodiment 3 of a control method of the present invention, which may specifically include:

[0075] Step 301, the downlink scheduling of the MAC layer is successful, and the HARQ ACK fed back by the user equipment is received;

[0076] Step 302, judging whether the SR of the user equipment is received within N SR periods; if not received, execute step 303; if received, execute step 304;

[0077] Step 303, enabling pre-scheduling for the user equipment;

[0078] Step 304, MAC scheduling;

[0079] Specifically, pre-scheduling may be enabled for the user equipment, to force uplink scheduling for the user equipment, and to allocate uplink grant resources for the user equipment.

[0080]Step 305, acquiring the content carried by the TB on the uplink authoriza...

Abstract

An embodiment of the present invention provides a control method and a control device, wherein the method includes: sending a radio resource control RRC connection reconfiguration message to user equipment, and starting a timer; when the timer expires, if it is determined that the If the RRC connection reconfiguration message is not effective for the user equipment, cancel the execution of the reconfiguration operation corresponding to the RRC connection reconfiguration message, and maintain the RRC connection state of the user equipment; the determining the RRC connection reconfiguration The message does not take effect for the user equipment, including: judging whether the RRC connection reconfiguration message is sent successfully; if the RRC connection reconfiguration message is not sent successfully, then determining that the RRC connection reconfiguration message is not valid for the user equipment take effect. The embodiment of the present invention can reduce the call drop rate of the LTE system.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a control method and a control device. Background technique [0002] In the LTE (Long Term Evolution, long-term evolution) system, the purpose of RRC (Radio Resource Control, unlimited resource control) connection reconfiguration is to modify the RRC connection, for example, to establish, modify, and release RB (Radio Bearer, radio bearer), in the eNB Handover between (Evolved Node B, evolved base station) or within eNB, and preparation, modification, release measurement, etc. [0003] Specifically, the eNB may send an RRC connection reconfiguration message to the UE (User Equipment, user equipment). After receiving the RRC connection reconfiguration message sent by the eNB, the UE may configure the current RRC connection according to the configuration items in the RRC connection reconfiguration message. Perform a reconfiguration operation. If the reconfiguration...
