It is understood that the target RRC message may be selected from any other RRC message requiring activated AS security, in addition to the above three RRC messages, which is not limited.

The following describes in detail a message sending method and a message receiving method according to an embodiment of the present application with reference to the accompanying drawings.

Referring to fig. 2, fig. 2 is a flowchart of a message sending method according to an embodiment of the present invention, where the method is applied to a terminal, and as shown in fig. 2, the method includes the following steps:

step 201: and under the condition that the terminal is in a non-RRC connected state and needs to send a target RRC message to network side equipment, initiating a random access process.

In this embodiment, the target RRC message is an RRC message that requires activated AS security. The Random Access procedure may be selected as a conventional Random Access procedure, such as a 2-step (2-step) Random Access procedure, or a 4-step (4-step) Random Access procedure.

Step 202: and when the terminal enters an RRC connection state through the random access process, sending a target RRC message.

It should be noted that, when the terminal enters the RRC connected state from the non-RRC connected state, the terminal may be implemented through an RRC connection establishment (or RRC connection establishment, or RRCSetup) procedure, or may be implemented through an RRC connection resume (or RRC connection resume) procedure. This is explained below.

The first condition is as follows: the terminal enters an RRC connected state through an RRC connection establishment process and sends a target RRC message after entering the RRC connected state. The specific process is as follows:

1. preparation phase

Once the RRC layer of the terminal has a need to send an RRC message (target RRC message) requiring activated AS security, the terminal triggers an RRC connection setup (RRCSetup) procedure to generate an RRC setup request message, submits the RRC setup request message to the bottom layer, and triggers generation of the content of the target RRC message. It is understood that the RRC establishment request message and the target RRC message are generated in the RRC layer, and the bottom layer here is a Protocol layer below the RRC layer, such as a Packet Data Convergence Protocol (PDCP), a Radio Link Control (RLC), and a MAC layer.

1) In the RRCSetup process, the terminal may set an establishment cause establishmentause value, which is at least any one of the following:

multiplexing the existing EstableshmentCause values, such as mo-data, mo-signal and the like;

secondly, the newly set EstableshmentCause value is at least any one of the following values:

→ the newly set establishmentause value may be related to a target RRC message, such as "XX configuration request message", setting the establishmentause value to "XX configuration request message"; the association with the target RRC message may be with the message type or form of the target RRC message or with the content of the target RRC message.

2) In the rrc setup procedure, the terminal may further perform at least one of the following:

firstly, checking of Unified Access Control (UAC) is not carried out, and an Access attempt is directly allowed;

and secondly, checking the UAC by using the set existing Access category (Access category) and/or Access identification (Access identity). That is, multiplexing the existing Access category and/or Access identity (ies), for example, setting the Access category to 7, the Access identity to 0, etc.;

checking UAC by new access type and/or access label. Namely, the UAC is checked by using the newly set Access category and/or Access identity (ies), and the UAC is at least any one of the following:

→ the new Access category and/or Access identity (ies) is independent of the target RRC message, i.e. all the target RRC messages are unified to the same value, e.g. the Access category is uniformly set to 11, the Access identity is set to 6, etc. The independence from the target RRC message can be independent from the message type or form of the target RRC message or independent from the content of the target RRC message.

→ the new Access category and/or Access identity (ies) is related to the target RRC message, e.g. for the "XX configuration request message", set Access category to 11, Access identity to 6, etc. The association with the target RRC message may be with the message type or form of the target RRC message or with the content of the target RRC message.

3) The trigger point in time for the generation of the content of the target RRC message may be at least one of:

Further, the triggering of the generation of the target RRC message content in the RRC connection establishment procedure may include at least one of:

→ in the Initiation phase (Initiation) of the RRC connection initialization procedure, triggering the generation of the content of the target RRC message;

→ in the operation procedure (Actions related to transmission of RRC setup request message) related to RRC setup request message transmission, triggering generation of the content of the target RRC message;

→ after the terminal receives the RRC establishment message (Reception of the RRC establishment by the UE) and before the content of the RRC establishment complete (RRCSetupcomplete) message is generated, triggering the generation of the content of the target RRC message;

→ in the process of generating the content of the RRC setup complete message after the terminal receives the RRC setup message, trigger the generation of the content of the target RRC message;

→ after the terminal receives the RRC establishment message and submits the RRC establishment completion message to the bottom layer, the generation of the content of the target RRC message is immediately triggered;

→ after the terminal successfully sends the RRC setup complete message to the network side device, the generation of the content of the target RRC message is triggered.

4) After the content in the target RRC message is generated, the terminal may store the content in the target RRC message using the first mathematical expression, or may not store the content in the target RRC message.

Further, the first mathematical expression may include at least one of: variables, arrays, constructs, and the like. That is, after the content of the target RRC message is generated, the terminal may store it using any mathematical expression form, such as a variable, an array, and/or a structure.

Optionally, after the content in the target RRC message is generated, the terminal may further set the content in the target RRC message as a part of the content of the RRC setup complete message, or not set the content in the target RRC message as a part of the content of the RRC setup complete message.

5) The RRC layer of the terminal may generate an RRCsetupRequest message with the establishmencause as a corresponding value, and submit it to the bottom layer.

2. Random Access (RACH) phase

In this stage, the MAC layer of the terminal initiates a random access procedure, and submits the MAC PDU with the RRCSetupRequest message to the physical layer and sends it to the network side device. The terminal successfully completes RACH and receives RRC establishment (RRCSetup) message sent by the network side equipment, and triggers the submission of target RRC message to the bottom layer.

6) The triggering event of the random access procedure may be at least one of:

multiplexing the existing trigger events; such as Initial access from RRC _ IDLE;

the newly set trigger event is at least any one of the following events:

→ independent of the target RRC message, i.e. unify all target RRC messages, such as MO-RRCmessage. The independence from the target RRC message can be independent from the message type or form of the target RRC message or independent from the content of the target RRC message.

→ related to the target RRC message, such as transmission of a separate target RRC message as a trigger event, such as a PUR configuration request message, an MBSCountingResponse message, an mbsinterentindication message, etc. The association with the target RRC message may be with the message type or form of the target RRC message or with the content of the target RRC message.

7) For the point in time that triggers the submission of the target RRC message to the underlay, at least one of the following may be used:

after a terminal receives an RRC establishment message (of the RRC establishment by the UE) and before the content of an RRC establishment completion (RRCSetupcomplete) message is generated, triggering and submitting a target RRC message to a bottom layer;

Optionally, at least one of the following relationships may exist between the RRC establishment complete message and the target RRC message:

the content of the target RRC message is a part of the content of the RRC setup complete message, and the target RRC message is sent as a part of the RRC setup complete message. That is, in this case, the terminal only sends the RRC setup complete message, and only one RRC message is sent to the network side device. In addition to this, the content of the target RRC message may be in its corresponding RRC message, instead of being in the RRC setup complete message, that is, the terminal sends two RRC messages to the network side device.

Multiplexing a target RRC message and an RRC establishment completion message in the same MAC PDU for transmission; at least any one of the following:

the → RRC setup complete message precedes the target RRC message; in other words, it may be: the RRC establishment completion message is positioned in front of the MAC PDU, and the target RRC message is positioned behind the MAC PDU;

the → RRC setup complete message is located after the target RRC message; in other words, it may be: the target RRC message is located at the front within the MAC PDU and the RRC setup complete message is located at the back within the MAC PDU.

It is understood that the RRC recovery request or the RRC recovery request1 message and the target RRC message are generated in the RRC layer, where the bottom layer is a Protocol layer below the RRC layer, such as a Packet Data Convergence Protocol (PDCP), a Radio Link Control (RLC), and a MAC layer.
