Description

Radio resource control RRC connection method, device and terminal

Technical field

The present invention relates to the field of communications, and in particular to a method, an apparatus, and a terminal for connecting a radio resource control RRC.

Background technique

Machine to Machine (M2M) communication is an important subject of the fifth generation of mobile communication technology (5G), and an important application field for wireless communication in the future. In the M2M project, for the characteristics of low-cost low-throughput type terminals, a sub-topic of the NarowBand-Internet of Things (NB-IoT) is proposed: that is, NB-IoT in the 200khz band. A low-cost wireless communication service is provided by a low-cost terminal (User Equipment, UE for short).

One feature of NB-IoT devices is low mobility, low throughput and low power consumption, so the current 3rd Generation Partnership Project (3GPP) standard has reached an agreement: NB-IoT device connection The mode does not support mobility processing. If the UE changes the serving cell in the connected mode, it needs to go to the idle mode to trigger the camped cell update. However, in the radio resource control (RRC) connection establishment process (including four RRC messages in the RRC connection establishment process), before receiving the fourth RRC message (RRC connection establishment or RRC connection recovery), the UE receives the fourth RRC message. Also in idle mode. According to current standards, UEs in idle state need to perform radio quality measurement and cell selection and reselection decisions. There are two problems: due to the low mobility of NB-IoT, it is unlikely that the UE will change the serving cell in the short time of the RRC connection establishment process, so the wireless quality measurement in this process will only waste the UE. The power consumption, which is inconsistent with the low power consumption requirement of the NB-IoT system; in addition, if the cell reselection occurs in the RRC connection establishment process of the NB-IoT UE, the message sent by the network side in the original cell is not received by the UE. Moreover, the radio quality of the new cell is not much better than the original cell in a short time, so reselection in the RRC connection establishment process may result in unnecessary call loss.

For the UE in the idle state of the related art, the problem of radio quality measurement and cell selection and reselection decision is required, and there is no effective solution at present.

The UE receives the base station to send an RRC connection setup or an RRC connection recovery.
The method according to claim 2, wherein the UE stops the radio quality measurement operation and the cell selection and reselection operation in the process of the UE transmitting the random access preamble to the base station, or in the UE direction The base station sends an RRC connection request or an RRC connection recovery request procedure.
The method of claim 3, wherein

And the sending, by the UE, the random access preamble to the base station, where the UE sends a random access preamble to the base station before the UE sends a random access preamble to the base station, where the UE sends a random access preamble to the base station. After the UE sends a random access preamble to the base station;

The process of the UE sending an RRC connection request or an RRC connection recovery request includes The next one: the UE sends an RRC connection to the base station when the UE sends an RRC connection request or an RRC connection recovery request to the base station before the UE sends an RRC connection request or an RRC connection recovery request to the base station. After request or RRC connection recovery request.
The method according to claim 4, wherein the UE random access failure condition comprises at least one of the following: after the UE sends the random access preamble to the base station, the UE does not receive the predetermined time a random access response fed back by the base station; after the UE sends the RRC connection request or the RRC connection recovery request to the base station, the RRC connection establishment or RRC connection recovery fed back by the base station is not received within the predetermined time.
A radio resource control RRC connection device is applied to the user equipment UE side, and includes:

Stopping the module, and setting the UE in the idle state to stop the radio quality measurement operation and the cell selection and reselection operation in the process of initiating random access to the base station;

Determining a module, setting to determine whether random access is successful;

The connection module is set to enter the connection mode when the random access is successful;

The recovery module is configured to resume the radio quality measurement operation and the cell selection and reselection operations when the random access fails.
The apparatus of claim 6 wherein said apparatus further comprises:

The initiating module is configured to initiate a process of random access to the base station, where the initiating module includes: a first sending unit, configured to send a random access preamble to the base station; and a first receiving unit, configured to receive the base station Sending a random access response; the second sending unit is configured to send an RRC connection request or an RRC connection recovery request to the base station; and the second receiving unit is configured to receive, by the base station, an RRC connection establishment or an RRC connection recovery.
The apparatus of claim 7, wherein said stopping module stops a radio quality measurement operation and a cell selection and reselection operation at said first transmitting unit to said base The station sends the random access preamble, or the second sending unit sends an RRC connection request or an RRC connection recovery request to the base station.
The device according to claim 8, wherein

The first sending unit sends the random access preamble process to the base station, where the first sending unit sends the first sending unit to the base station before sending the random access preamble to the base station. When the random access preamble is sent, the first sending unit sends a random access preamble to the base station;

And the sending, by the second sending unit, the RRC connection request or the RRC connection recovery request process to the base station, where the second sending unit sends an RRC connection request or an RRC connection recovery request to the base station, and the second When the transmitting unit sends an RRC connection request or an RRC connection recovery request to the base station, the second sending unit sends an RRC connection request or an RRC connection recovery request to the base station.
The apparatus according to claim 9, wherein the case of random access failure comprises at least one of the following: the first sending unit, after transmitting the random access preamble to the base station, the second receiving within a predetermined time The unit does not receive the random access response fed back by the base station; after the second sending unit sends the RRC connection request or the RRC connection recovery request to the base station, the second receiving unit does not receive the preset time The RRC connection establishment or RRC connection recovery reported by the base station.
A terminal comprising:

processor;
