Detailed Description
So that the manner in which the features and techniques of the embodiments of the present application can be understood in more detail, a more particular description of the application, briefly summarized below, may be had by reference to the appended drawings, which are not intended to be limiting of the embodiments of the present application.
Before describing the cell switching processing method provided by the embodiment of the present application in detail, a brief description is given to a related art cell switching process.
The New Radio (NR) system supports a handover procedure of a connection state terminal device. When a terminal device using a network service moves from one cell to another cell, or due to adjustment of radio transmission traffic load, active operation maintenance, equipment failure, etc., the system transfers the communication link between the terminal device and the original cell to the new cell, i.e., performs a handover procedure, in order to ensure continuity of communication and quality of service.
The cell switching procedure applicable to NR systems, as shown in fig. 1, comprises the following three phases:
stage 1 (including steps 1 to 5), handover preparation: including measurement control and reporting, handover requests, and acknowledgements.
Stage 2 (comprising steps 6 to 8), the handover performs: the terminal device immediately executes the switching process after receiving the switching command, i.e. the terminal device disconnects the source cell and connects with the target cell (e.g. executes random access, sends an RRC switching completion message to the target network device, etc.); and (5) state transition and data forwarding of a Secondary Node (SN).
Stage 3 (comprising steps 9 to 12), the handover is completed: the target cell performs Path switching (Path Switch) with an access and mobility management function (Acess and Mobility Management Function, AMF) and a user plane function (User Port Function, UPF) releasing the terminal device context of the source network device.
Cell handover procedure applicable to long term evolution (Long Term Evolution, LTE) system, as shown in fig. 2, includes the following three phases:
stage 1 (including steps S1 to S6), handover preparation: the method comprises the steps that source network equipment configures terminal equipment to carry out measurement reporting, and the source network equipment sends a switching request to target network equipment based on a measurement result of the terminal equipment. After the target network device agrees to the handover request, the target network device configures an RRC message for the terminal device, where the RRC message carries mobile control information (Mobility Control Information), and the RRC message further includes resources for RACH, cell-Radio Network Temporary Identifier, C-RNTI, a target network device security algorithm, a system message of the target network device, and the like.
Stage 2 (including steps S7 to S11), the handover is performed: the source network device forwards Mobility Control Information to the terminal device through the switching command, and the terminal device initiates a random access flow to the target network device after receiving the switching command. Meanwhile, the source network device transmits a Sequence Number (SN) state transition (STATUS TRANSFER) to the target network device for co-sitting the receiving state of an uplink packet data convergence protocol (Packet Data Convergence Protocol, PDCP) SN and the transmitting state of a downlink PDCP SN of the target network device.
Stage 3 (including steps S12 to S18), the handover is completed: when the terminal device successfully accesses the target network device, the target network device sends a path switch REQUEST (PATH SWITCH REQUEST) message to REQUEST the mobility management entity (Mobility Management Entity, MME) to switch the downlink path. After the path switching is completed, the target network device instructs the source network device to release the context of the terminal device, and the cell switching is completed.
A brief description of conditional handover follows.
Aiming at the problems of frequent switching and easy failure of switching in a high-speed mobile scene and a high-frequency deployment scene, conditional handover is introduced for an LTE system and an NR system. As shown in fig. 3, the terminal device performs cell measurement, configuration and reporting with the source network device; the source network equipment and the target network equipment are subjected to switching preparation; and when the terminal equipment meets the triggering condition, switching to the target network equipment. Conditional Handover, by configuring a Handover (HO) command (command) for a terminal device in advance, the problem that the terminal device has passed late when it is to be handed over due to an excessively long Handover preparation time is avoided. And, for the high-speed rail scenario, the running track of the terminal device is specific, so the source network device may allocate the target network device to the terminal device in advance, and the HO command includes a condition for triggering the terminal device to perform handover, and when the allocated condition is satisfied, the terminal device initiates an access request to the target network device. However, in Conditional handover there may be the following problems:
since the source network device cannot explicitly predict when the terminal device triggers the CHO condition, the source network device cannot explicitly predict when the terminal device initiates the cell CHO. In case the source network device is not able to make sure that the terminal device has successfully performed the cell handover, it is still possible for the source network device to continue sending RRC messages to the terminal device. How the terminal device responds to the RRC message sent by the source network device during the conditional handover is not yet available.
Based on the above-mentioned problems, the present application provides a method for processing a radio resource control message, and the method for processing a radio resource control message according to the embodiment of the present application can be applied to various communication systems, for example: global system for mobile communications (Global System of Mobile communication, GSM), code division multiple access (Code Division Multiple Access, CDMA), wideband code division multiple access (Wideband Code Division Multiple Access, WCDMA) systems, general packet radio service (General Packet Radio Service, GPRS), LTE systems, LTE frequency division duplex (Frequency Division Duplex, FDD) systems, LTE time division duplex (Time Division Duplex, TDD), universal mobile telecommunications system (Universal Mobile Telecommunication System, UMTS), worldwide interoperability for microwave access (Worldwide Interoperability for Microwave Access, wiMAX) communication systems, or 5G systems, etc.

An optional processing flow of the processing method of the radio resource control message provided by the embodiment of the application is shown in fig. 5, and includes the following steps:
it should be noted that, the embodiment of the present application is applied to a process of performing conditional handover from a source cell to a target cell by a terminal device, that is, the terminal device is being handed over from the source cell to the target cell. The network equipment of the source cell is the source network equipment, and the network equipment of the target cell is the target network equipment.
In step S201, the terminal device receives the RRC message.
In some embodiments, the source network device is unable to explicitly predict when the terminal device initiates a cell condition handover. In case the source network device is not able to make sure that the terminal device has successfully performed the cell handover, it is still possible for the source network device to continue sending RRC messages to the terminal device.
If the terminal device supports downlink and simultaneously receives data, the terminal device continues to monitor downlink channels of the source network device, such as a physical downlink control channel (Physical Downlink Control Channel, PDCCH) and a physical downlink shared channel (Physical Downlink Shared Channel, PDSCH).
In some embodiments, the RRC message is an RRC reconfiguration message sent by the source network device. Of course, the RRC message may also be other RRC messages than the RRC reconfiguration message, which are sent by the source network device to the terminal device.
Step S202, the terminal equipment responds to the RRC message based on the content of the RRC message.
In the embodiment of the present application, the terminal device continues to execute the conditional handover based on the content of the RRC message; or executing corresponding operation based on the instruction carried by the RRC message.
In some embodiments, in the case where the RRC message includes a first handover command, the terminal device stops the conditional handover being performed, and performs cell handover based on the first handover command. In a specific implementation, the terminal device performs cell handover based on the configuration information in the first handover command. The first switching command is used for triggering the terminal equipment to immediately execute cell switching when receiving the first switching command; the cell switch triggered by the first switch command is the cell switch shown in fig. 1 or fig. 2 in the present application.
Or if the RRC message includes the first handover command, the terminal device continues to perform the current conditional handover being performed, and if the conditional handover is successful, that is, the target cell is successfully accessed, the first handover command is ignored. And if the conditional handover fails, executing cell handover based on the first handover command. In a specific implementation, the terminal device performs cell handover based on the configuration information in the first handover command.
In other embodiments, the terminal device stops the executing conditional handover in case the RRC message comprises a conditional handover de-configuration (CHO deconfiguration) command and the conditional handover de-configuration command comprises a first candidate cell for the executing conditional handover. For example, the terminal device is performing a conditional handover from a source cell to a target cell, and the terminal device receives an RRC message including the target cell, and the terminal device stops the currently performed conditional handover to the target cell. In a specific implementation, the terminal device may further delete the conditional handover configuration information of the first candidate cell.
After stopping the currently executed conditional switching, the terminal device executes conditional switching to the second candidate cell under the condition that the second candidate cell meets the condition of executing the conditional switching and the second conditional switching command corresponding to the second candidate cell is valid. That is, in the case where the configuration information of the second candidate cell exists in the second conditional handover command and the second conditional handover command is valid, the terminal device performs conditional handover to the second candidate cell. Wherein, in a case where a timer for the second conditional handover command is not configured and the CHO deconfiguration command does not include a second candidate cell, the second conditional handover command is considered valid; alternatively, the second conditional handover command is considered valid in case said CHO deconfiguration command does not comprise the second candidate cell and the configured timer for the second conditional handover command has not timed out. In specific implementation, the terminal device sends an RRC response message to the source network device, where the RRC response message is used to respond to the RRC message sent by the source network device; the RRC response message is used to notify the source network device that the terminal device has stopped the currently performed conditional handover, deleted the conditional configuration information of the first candidate cell, and performed the conditional handover to the second candidate cell.
The terminal device maintains connection with the source network device in the case that the third candidate cell satisfying the condition for performing the conditional handover is not present after stopping the conditional handover currently performed. Wherein the third candidate cell does not belong to a candidate cell for the conditional handover being performed. In specific implementation, the terminal device sends an RRC response message to the source network device, where the RRC response message is used to respond to the RRC message sent by the source network device; the RRC response message is used to inform the source network device that the terminal device has stopped the currently performed conditional handover and deletes the conditional configuration information of the first candidate cell.
In still other embodiments, in the event that the RRC message includes a CHO deconfiguration command and the conditional handover de-configuration command includes a fourth candidate cell, the conditional handover configuration information of the fourth candidate cell is deleted. Wherein the fourth candidate cell does not belong to the candidate cell of the conditional handover being performed, i.e. the fourth candidate cell is different from the first candidate cell. In the implementation, if the terminal device supports dual connection, that is, the terminal device supports uplink direction and simultaneously transmits data, the terminal device transmits an RRC response message to the source network device, where the RRC response message is used to respond to the RRC message transmitted by the source network device. After receiving the RRC response message sent by the terminal equipment, the source network equipment instructs the source network equipment corresponding to the fourth candidate cell to release the radio resource and the configuration reserved for the terminal equipment.
In the embodiment of the present application, if the RRC message is an RRC reconfiguration message, the corresponding RRC response message is an RRC reconfiguration complete message.
In still other embodiments, in the case that the RRC message does not include the first handover command and the conditional handover de-configuration command, the terminal device ignores the RRC message; the terminal device ignores the RRC message, which means that after the terminal device sends the RRC message to the source network device, the terminal device does not update the configuration information of the terminal device by using any configuration information in the RRC message, and does not send an RRC response message to the source network device.
Or if the RRC message does not include the first handover command and the conditional handover de-configuration command, if the terminal device supports uplink direction simultaneous data transmission, the terminal device transmits an RRC reject message to the source network device. In a specific implementation, if the RRC message is an RRC reconfiguration message, the RRC reject message is an RRC reconfiguration reject message. The RRC reject message may carry a reject cause, e.g. that the terminal device is performing a conditional handover. When the RRC reject message carries the reject reason, the cause value is increased in the RRC reject message. In the embodiment of the application, if the terminal equipment executes the conditional switching successfully, the terminal equipment is accessed to the target cell; if the terminal equipment fails to execute the conditional handover, the terminal equipment initiates an RRC connection reestablishment process to the source cell.
In still other embodiments, the terminal device stores configuration information in the RRC message in case the RRC message does not include a first handover command and a conditional handover de-configuration command. Here, after storing the configuration information in the RRC message, the terminal device continues to perform the current conditional handover, and does not immediately apply the configuration information in the RRC message. If the condition switching is successful, the terminal device deletes all configuration information related to the source network device; if the condition switch being executed fails, the terminal equipment applies the configuration information in the RRC message to update the configuration of the terminal equipment and initiates an RRC reconfiguration complete message to the source cell.
In the embodiment of the present application, the terminal device performs different processes according to different contents of the RRC message sent by the source network device, for example: continuing the condition switching of the current execution; or performing a cell handover based on the first handover command; or stopping the currently executed conditional switching and deleting the configuration information of the conditional switching candidate cell; or ignore RRC message; or after the configuration information in the RRC message is reserved, deleting the configuration information of the source cell or sending an RRC reconfiguration completion message to the source cell according to the result of the currently executed conditional handover. Therefore, the terminal equipment can be prevented from triggering an unnecessary RRC reestablishment process after receiving the RRC message; the interruption and loss of data in the cell switching process can be reduced. And the terminal equipment timely sends the deletion information of the candidate cell to the source network equipment, which is helpful for the source network equipment to instruct the candidate cell to release resources and reduce the waste of network resources.
