The embodiment of the application provides a solution to the problem of increased delay of the terminal entering the connected state. In order to facilitate a clearer understanding of the embodiments of the present application, some related technical knowledge will be described first.

1. RRC connection setup procedure

Fig. 2 is one of signaling interaction diagrams of an RRC connection setup procedure in the prior art, as shown in fig. 2, when an upper layer requests RRC connection setup, a terminal in an Idle state initiates an RRC connection setup procedure, and the terminal initiates the procedure to trigger a random access procedure, where an RRC setup request (RRCSetup request) message may be carried in message 3 (Msg 3), an RRC setup complete message may be carried in message 5 (Msg 5), and once the terminal receives the RRCSetup message, the terminal enters a connected state, and the RRCSetup message may be carried in Msg4 or may not be carried in Msg 4.

Before the terminal receives the RRCSetup message, the terminal needs to continue to perform measurement and evaluation of cell reselection related to cell reselection, if the criterion of cell reselection is met, the terminal performs cell reselection and indicates that the upper layer releases the RRC connection and the reason of release is "RRC connection failure".

2. RRC connection recovery procedure

Fig. 3 is a signaling interaction diagram of an RRC connection recovery procedure in the prior art, AS shown in fig. 3, when an upper layer requests RRC connection recovery or an Access Stratum (AS) layer triggers RRC connection recovery, a terminal in an INACTIVE state initiates an RRC connection recovery procedure, and once the terminal receives an RRC recovery (rrreport) message, the terminal enters a connected state. The terminal initiates the procedure to trigger the random access procedure, an RRC restore request (rrcresemerequest) message may be carried in Msg3, an RRC restore complete (rrcresemecomplete) message may be carried in Msg5, and an rrcreseme message may or may not be carried in Msg 4.

Before the terminal receives the RRCResume message, the terminal needs to continue to perform measurement and evaluation of cell reselection related to cell reselection, if the criterion of cell reselection is met, the terminal performs cell reselection, enters an Idle (Idle) state, and indicates that an upper layer releases RRC connection and the reason of release "RRC connection recovery fails".

3. RRC connection reestablishment procedure

Fig. 4 is a signaling interaction diagram of an RRC connection reestablishment procedure in the prior art, as shown in fig. 4, when a terminal initiates an RRC connection reestablishment procedure, a connection reestablishment request is initiated on a selected cell, for example, during the operation of a T301 timer, it may be understood that, during the period from when the terminal initiates the RRC connection reestablishment request to when the terminal receives an RRC connection reestablishment message, the terminal needs to measure the signal state of the selected cell all the time, and if the selected cell no longer meets the cell selection criterion, i.e., the selected cell is no longer a suitable cell (useable cell), the terminal enters the connected state and instructs the upper layer to release the RRC connection and the reason of release "RRC connection reestablishment failure".

4. Taking the terminal initiating the RRC connection establishment procedure and the network side being the radio access network (Radio Access Network, RAN) as an example, specific timing of the terminal monitoring the PDCCH is described.

Fig. 5 is a second signaling diagram of the RRC connection establishment procedure in the prior art, and as shown in fig. 5, includes steps 501 to 508.

Step 501, the terminal decides to initiate an RRC connection establishment procedure, and triggers the bottom layer to initiate random access;

step 502, the terminal sends Msg1 to the network side device.

Specifically, msg1 may include a random access preamble (preamble).

In step 503, the terminal listens to the PDCCH to receive Msg2.

Step 504, the terminal receives Msg2 from the network side device.

Specifically, msg2 may include a random access channel (Random Access Channel, RACH) response (response).

Step 505, the terminal sends Msg3 to the network side device.

Specifically, msg3 may comprise an rrcsetup request message.

Step 506, the terminal listens to the PDCCH to receive Msg4.

Step 507, the terminal receives Msg4 from the network side device.

Specifically, msg4 may include contention resolution (Contention Resolution).

Step 508, the terminal listens to the PDCCH to receive the RRCSetup message until the T300 timer expires.

The measurement method provided by the embodiment of the application can be applied to the terminal in the RRC connection establishment process, the RRC connection recovery process or the RRC connection reestablishment process.

FIG. 6 is a schematic flow chart of a measurement method according to an embodiment of the present application, as shown in FIG. 6, the method includes a step 601; wherein:

in step 601, under the condition that the first timer is running, the terminal preferentially executes measurement related to cell selection or reselection, or the terminal preferentially monitors the PDCCH.

Wherein the first timer comprises at least one of:

1. a timer for RRC connection establishment procedure;

2. a timer for RRC connection recovery procedure;

3. a timer for RRC connection re-establishment procedure.

Specifically, in the related art, during the period of monitoring the PDCCH, the terminal cannot perform inter-frequency or inter-system measurement simultaneously, which results in that the terminal cannot perform inter-frequency or inter-system cell reselection related measurement and cell reselection evaluation, during which, if the signal quality or signal strength of the serving cell is poor, the terminal may not reselect to a better inter-frequency or inter-system cell, the terminal cannot perform inter-frequency or inter-system measurement only after the RRC connection establishment fails, and selects a cell with better signal quality or signal strength to reinitiate the RRC connection establishment procedure, which results in an increase in the delay of the terminal entering the connected state.

In this embodiment of the present application, under the condition that the first timer is running, the terminal may preferentially perform measurement related to cell selection or reselection, or preferentially monitor the PDCCH; it may also be appreciated that the terminal may preferentially perform cell selection or reselection related measurements during RRC connection establishment, RRC connection recovery, and/or RRC connection reestablishment, or preferentially monitor the PDCCH. According to the embodiment of the invention, the terminal can preferentially execute the cell selection or reselection related measurement under the condition that the first timer is running, so that the terminal can timely reselect a better cell as a service cell, further, the time delay of the terminal entering a connection state can be effectively reduced, and the mobility of the terminal is ensured.

Alternatively, the determination of whether the terminal preferentially performs cell selection or reselection related measurements or preferentially listens to the PDCCH may be specifically implemented by protocol configuration, pre-configuration or based on the terminal.

In one embodiment, the timer used for the RRC connection setup procedure may be a T300 timer.

In one embodiment, the timer for the RRC connection recovery procedure may be a T319 timer.

In the embodiment of the invention, the terminal can preferentially execute the cell selection or reselection related measurement under the condition that the first timer is running, so that the terminal can timely reselect a better cell as a service cell, further the time delay of the terminal entering a connection state can be effectively reduced, and the mobility of the terminal is ensured.

Optionally, the cell selection or reselection related measurement may include at least one of:

1) Different frequency measurement;

specifically, the inter-frequency measurement is, for example, an inter-frequency measurement.

2) Different system measurement;

4) Serving cell measurements.

Optionally, the terminal preferably performs measurement related to cell selection or reselection, or an implementation manner that the terminal preferably listens to PDCCH may include:

and under the condition that the terminal does not support to simultaneously execute the cell selection or reselection related measurement and the PDCCH monitoring, the terminal preferentially executes the cell selection or reselection related measurement, or the terminal preferentially monitors the PDCCH.

Specifically, if the terminal cannot simultaneously perform the measurement related to cell selection or reselection and monitor the PDCCH, the terminal may preferentially perform the measurement related to cell selection or reselection, or preferentially monitor the PDCCH; it may also be understood that, only for the case where there is a conflict between the terminal performing the cell selection or reselection related measurement and listening to the PDCCH, the terminal may be set to preferentially perform the cell selection or reselection related measurement, or preferentially listen to the PDCCH.

in the target time, the terminal preferentially executes cell selection or reselection related measurement, or the terminal preferentially monitors PDCCH;

specifically, the terminal may preferentially perform cell selection or reselection-related measurement within the target time, or the terminal preferentially listens to the PDCCH.

Wherein the target time includes at least one of:

Taking the first threshold as a percentage as an example, if the first threshold is 50% and the length of T300 is 1s, the target time may be expressed as the time after the time when T300 runs to 1s×50% =0.5 s.

Alternatively, the target time may be a continuous period of time, or the target time may include at least two periods of time spaced apart.

Specifically, the target time may include one time period, or a plurality of time periods.

alternatively, if the target time is related to the transmission time of Msg1 or Msg3 or the reception time of Msg2 or Msg4, the target time may be determined by the MAC layer of the terminal and indicated to the RRC layer.

Optionally, another specific implementation manner of determining the target time by the terminal is provided in the embodiment of the present application.

The RRC layer of the terminal determines the target time;

the RRC layer of the terminal submits the target time to the second protocol layer of the terminal; the second protocol layer includes a MAC layer or a PHY layer.

Specifically, the RRC layer of the terminal may indicate the target time to the bottom layer (second protocol layer);

Alternatively, if the target time is expressed in absolute time, expressed in time pattern, or related to T300, T319, or T301, the target time may be decided by the RRC layer of the terminal and indicated to the MAC.

Optionally, the terminal may receive configuration information from a network side device;

wherein the configuration information is used to indicate any one of the following:

1. the terminal preferentially executes the cell selection or reselection related measurement in the target time, or the terminal preferentially monitors the PDCCH;

2. and the terminal does not preferentially execute cell selection or reselection related measurement in the target time, or does not preferentially monitor PDCCH.

Specifically, whether the terminal performs the following operations may be agreed by a protocol or configured by a network: in the target time, the terminal preferentially executes cell selection or reselection related measurement, or preferentially monitors PDCCH;

in one embodiment, if the terminal can execute the above operation by agreement, the terminal can always execute the above operation once the target time is obtained; if the network side configures the terminal to execute the operation, the terminal executes the operation only when the terminal obtains the target time and the network side configures the terminal to execute the operation.

The network side may use the Z bit indication field to configure the terminal to perform the above operation or not, and in one embodiment, the Z bit indication field may be a 1bit indication field.

For example, when the indication field exists and the value is true, the terminal executes the operation; when the indication field does not exist, the terminal does not execute the operation;

for another example, when the indication field is 1/true, the terminal performs the above operation, and when the indication field is 0/false, the terminal does not perform the above operation, or vice versa.

The terminal is a terminal with a correlation capability, for example, a capability of supporting acquisition of a target time.

The measurement method provided in the embodiment of the present application is exemplified below.

1. Measurement for a terminal to perform cell selection or reselection related preferentially

In case T300, T319 or T301 is running, i.e. during RRC connection setup, RRC connection recovery or RRC connection re-establishment, the terminal preferably performs cell selection or reselection related measurements.

The cell selection or reselection related measurements include at least one of:

1. different frequency or different system frequency measurement;

2. the same frequency measurement;

3. measurement of serving cells.

Optionally, the terminal performs cell selection or reselection related measurements preferentially in the target time.

2. The terminal monitors PDCCH preferentially

In case T300, T319 or T301 is running, i.e. during RRC connection establishment, RRC connection restoration or RRC connection reestablishment, the terminal prioritizes RRC connection establishment, RRC connection restoration or RRC connection reestablishment procedures, i.e. the terminal listens to the PDCCH.

Optionally, the implementation manner that the terminal monitors the PDCCH preferentially may include: if the terminal can simultaneously execute the cell selection or reselection related measurement and monitor the PDCCH, the terminal executes the cell selection or reselection related measurement, otherwise, the terminal does not execute the cell selection or reselection related measurement and only executes the monitoring PDCCH.

For example, if the terminal can perform the same-frequency measurement and monitor the PDCCH at the same time, and the triggering condition of the same-frequency measurement is satisfied, the terminal performs the same-frequency measurement; if the terminal cannot simultaneously perform measurement of different frequencies or different system frequencies and monitor the PDCCH, the terminal does not perform the different frequencies or the different system measurement even if the triggering condition of the different frequencies or the different system measurement is met. In other words, the terminal may perform cell selection or reselection related measurements.

The embodiment of the application can be applied to 2G to 5G and subsequent evolution communication systems.

According to the embodiment of the invention, the terminal can execute measurement required by different frequency reselection in the processes of RRC connection establishment, RRC connection recovery or RRC connection reestablishment, so that the terminal can reselect a better cell in time, and the mobility of the terminal is ensured.
