Detailed ways

The technical solutions in the embodiments of the present application will be described below in conjunction with the accompanying drawings.

The main application scenarios of 5G are: enhanced mobile broadband (eMBB), ultra-reliable and low latency communications (URLLC), and massive machine type communications (mMTC) .

eMBB aims at users to obtain multimedia content, services and data, and its demand is growing rapidly. eMBB may be deployed in different scenarios, such as indoors, urban areas, rural areas, etc., and its capabilities and requirements vary greatly. Typical applications of URLLC include: industrial automation, power automation, telemedicine operations (surgery), traffic safety protection, etc. The characteristics of mMTC include: high connection density, small data volume, delay-insensitive services, low cost and long service life of the module.

In the early deployment of NR, complete NR coverage is difficult to obtain, so the typical network coverage is a wide-area long term evolution (LTE) coverage mode and an NR island coverage mode. A large amount of LTE is deployed below 6GHz, and there is very little spectrum below 6GHz that can be used for 5G. Therefore, NR requires spectrum applications above 6GHz, and high-frequency band coverage is limited and signal fading is fast. In order to protect mobile operators' early investment in LTE, a close interconnection working mode between LTE and NR is proposed.

In the NR system, the size of the DL RRC is very large due to configurations such as BWP and CSI-RS. The constraint size of NR PDC P for the input PDCP SDU is 9000 bytes. In order to support the support of RRC PDUs greater than 9000 bytes, R16 supports segmented transmission of DL messages. The supported DL message segmented messages include, for example, RRC reconfiguration (Reconfiguration) messages and RRC recovery (Resume) messages. When a user equipment (user equipment, UE) receives a complete message and receives multiple segmented messages of a message, the air interface delay is different, which may increase the decoding failure rate after the user equipment receives multiple segmented messages.

In response to the foregoing problems, an embodiment of the application proposes a method for processing RRC messages, which is applied to a communication system. Please refer to FIG. 1. FIG. 1 is a schematic diagram of a communication system architecture provided by an embodiment of the application. The communication system includes network equipment. And terminal equipment. As shown in Figure 1, network devices can communicate with terminal devices. The communication system can be the global system for mobile communication (CSM), code division multiple access (CDMA) system, wideband code division multiple access (WCDMA) system, global Worldwide interoperability for microwave access (WiMAX) systems, LTE systems, 5G communication systems (such as NR), communication systems that integrate multiple communication technologies (such as communication systems that integrate LTE and NR technologies), or subsequent evolution Communication Systems. The form and quantity of the network equipment and terminal equipment shown in FIG. 1 are only for example, and do not constitute a limitation to the embodiment of the present application. In addition, the user equipment described in the embodiments of the present application may include various handheld devices with wireless communication functions, vehicle-mounted devices, wearable devices (such as smart watches, smart bracelets, pedometers, etc.), computing devices or connected to wireless Other processing equipment of the modem, etc. For ease of description, the devices mentioned above are collectively referred to as user equipment. The network equipment described in the embodiment of the present application includes a base station or a core network equipment.

Please refer to FIG. 2A. FIG. 2A is a schematic flowchart of an RRC message processing method provided by an embodiment of the present application, and the method includes:

Step 201: The network device sends a segmented message of the RRC message to the user equipment.

Wherein, the RRC message includes an RRC recovery message or an RRC reconfiguration message, and the segmented message of the RRC message carries first indication information, and the first indication information is used to indicate the message name or transaction of the RRC message Identifier or message type.

Optionally, in the LTE system, the above-mentioned RRC message may also include an RRC connection recovery message or an RRC connection reconfiguration message.

In the specific implementation, considering that there is an RRC PDU larger than 9000 bytes, the network device can divide the RRC message into multiple segmented messages and perform segmented transmission to the user equipment.

Step 202: Receive a segmented message of an RRC message from a network device, and start a first timer.

In this embodiment, the user equipment may receive the segmented message of the RRC message transmitted by the network device.

The first timer can be used to time multiple segment messages of the RRC message sent by the network device, and control the user equipment to receive all segment messages of the RRC message within the duration of the first timer. If the user equipment is in the first timer If all segment messages of the RRC message are not received within the duration of a timer, it indicates that the user equipment has failed to receive the RRC message.

Step 203: If the segment message of the RRC message is the last segment message of the RRC message, the user equipment decodes the RRC message according to all segment messages of the received RRC message.

In specific implementation, the first indication information carried in the segmentation message of the RRC message may indicate that the segmentation message is the last segmentation message of the RRC message, and if the segmentation message of the RRC message is the last segmentation message of the RRC message The segmented message indicates that the user equipment has received all the segmented messages of the RRC message, and further, the RRC message can be decoded according to all the segmented messages of the received RRC message.

In a possible example, the method may further include the following steps:

If the segment message of the RRC message is the first segment message of the RRC message, or the segment message of the RRC message is the first received segment message of the RRC message, then The user equipment executes the operation of starting the first timer.

Among them, in this embodiment, the RRC message may be an RRC reconfiguration message or an RRC recovery message.

In the embodiment of the present application, the network device divides the RRC message into multiple segment messages, and the multiple segment messages are arranged in order, so that the user equipment can start the first segment message after receiving the first segment message of the RRC message. A timer.

Or, if the network device sends other segment messages of the RRC message after sending the first segment message of the RRC message, if the other segment messages arrive at the user equipment earlier than the first segment message of the RRC message, then The user equipment can determine the segment message of the RRC message that is received first among the multiple segment messages of the RRC message, so that the user equipment can start the first segment message after receiving the segment message of the RRC message first. A timer.

In this possible example, when the first timer expires, if the user equipment does not receive all the segment messages of the RRC message, or if the user equipment receives all the segments of the RRC message Segment message, but the RRC message is not successfully decoded, the user equipment discards all segment messages of the RRC message.

If the user equipment receives all the segment messages of the RRC message, but fails to decode the RRC message successfully, the user equipment may discard all the segment messages of the RRC message.

In a possible example, if the segment message of the RRC message is the segment message of the RRC reconfiguration message in the current serving cell, the user equipment searches for the target cell, and if the target cell is found, initiates an RRC reconfiguration. During the connection process, if the target cell is not found, the user equipment is switched to an idle state.

Specifically, in the case where the user equipment has not received all the segment messages of the RRC message, or in the case where the user equipment has received all the segment messages of the RRC message, but has not successfully decoded the RRC message, if The segmented message of the RRC message is the segmented message of the RRC reconfiguration (reconfiguration) message in the current serving cell. The user equipment can search for a suitable target cell. If it finds a suitable target cell, it initiates the RRC reconnection process. To the target cell, switch the user equipment to an idle state.

In a possible example, if the segmented message of the RRC message is the segmented message of the RRC recovery message in the current serving cell, the user equipment re-initiates the RRC connection recovery process.

Specifically, in the case where the user equipment has not received all the segment messages of the RRC message, or in the case where the user equipment has received all the segment messages of the RRC message, but has not successfully decoded the RRC message, if The segmented message of the RRC message is the segmented message of the RRC resume (resume) message in the current serving cell, and the user equipment re-initiates the RRC connection recovery process.

Among them, the user equipment is in the RRC connected state, and the user equipment receives a segmented message of the RRC reconfiguration message sent by the network device, such as a DL segmented message, the segmented message carries the first indication information, and the RRC reconfiguration is received on the user equipment When the first segment message of the message, the user equipment starts the first timer, and the user equipment continues to wait to receive the segment message of the RRC reconfiguration message until the first indication information carried in the segment message indicates that the segment message is the RRC For the last segment message of the reconfiguration message, the user equipment decodes the RRC reconfiguration message according to all segment messages of the received RRC reconfiguration message. When the first timer expires and the user equipment does not receive all the segment messages of the RRC reconfiguration message, or the user equipment receives all the segment messages of the RRC reconfiguration message, but fails to decode the RRC reconfiguration message, the user equipment It is determined that the RRC reconfiguration fails, and further, the user equipment searches for the target cell, and if the target cell is found, initiates an RRC reconnection process, and if the target cell is not found, the user equipment switches to an idle state.

In a possible example, before the receiving the segmented message of the RRC message from the network device, the method may further include the following steps:

The user equipment receives the segmented message of the RRC recovery message sent by the network device, and if the identification information carried in the segmented message of the RRC recovery message is the same as the identification information carried in the RRC recovery request message, the user equipment stops the second timer. The user equipment continues to wait to receive the segment message of the RRC recovery message until the indication information carried in the segment message of the RRC recovery message indicates that the segment message is the last segment message of the RRC recovery message. The segmented message decodes the RRC recovery message.
