Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0045] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein.

[0046] To meet users' demands for service speed, latency, and high-speed mobility, fifth-generation (5G) mobile communication technology emerged. In a 5G network environment, to reduce air interface signaling and quickly restore wireless connections and data services, radio resource service states are defined. These radio resource services can include Radio Resource Control (RRC), also known as Radio Resource Management (RRM) or Radio Resource Allocation (RRA). This refers to the management, control, and scheduling of radio resources through specific strategies and methods to fully utilize limited wireless network resources while meeting quality of service requirements, ensuring coverage of planned areas, and maximizing service capacity and resource utilization. Taking RRC as an example, radio resource service states include RRC inactive (RRC_INACTIVE), RRC idle (RRC_IDLE), and RRC connected (RRC_CONNECTED). In 5G (NR) networks, the purpose of RRC connection re-establishment is to restore previously established RRC connections. Reasons for RRC re-establishment include: reconfiguration failure, handover failure, and other failures. The network element-side message processing method provided in this application embodiment is used to solve the problem of terminal RRC reconstruction failure.

[0047] In this embodiment, the network element-side message processing method can be applied to network element-side devices. These devices may include core network elements or base stations. Core network elements may include Access and Mobility Management Functions (AMF), Mobility Management Entities (MME), etc. See also... Figure 1 This is a schematic diagram of a communication system provided in an embodiment of this application. In this communication system, the network element-side equipment is represented by base station 101, and the terminal is represented by user equipment 102 (User Equipment, UE). Figure 1 The number of UEs is N, and the specific number of UEs can be determined based on the actual application scenario.

[0048] The following describes the network element-side message processing method provided in the embodiments of this application. See [link to relevant documentation]. Figure 2 The method may include the following steps:

[0049] S201. Receive the wireless resource service connection restoration request message sent by the first terminal.

[0050] S202. If the first terminal is detected to meet the target conditions, a first message and a second message are sent to the first terminal respectively, so that the first terminal can restore the connection of the wireless resource service.

[0051] The first message is a connection restoration message for radio resource services, and the second message is a terminal contention resolution message. The target condition characterizes the condition under which the first terminal cannot successfully parse the first message when it simultaneously receives the first message and the second message.

[0052] Radio resource services may include radio resource control, radio resource management, radio resource scheduling, or radio resource allocation. For ease of description, this embodiment uses Radio Resource Control (RRC) as an example. In a 5G network, the purpose of RRC connection re-establishment is to restore a previously established RRC connection. Reasons for RRC re-establishment include reconfiguration failure, handover failure, and other failures. Therefore, when a terminal needs to restore a previously established RRC connection, it sends a connection restoration request message for a radio resource service (such as RRC) to the network element-side device (such as a base station).

[0053] When a network element device (such as a base station) receives a connection restoration request message for a radio resource service (such as RRC) sent by a first terminal, the network element device will check whether the first terminal meets the target conditions. That is, if the first terminal receives both a connection restoration request message for the radio resource service and a terminal contention resolution message at the same time, it will determine that it cannot successfully parse the connection restoration request message for the radio resource service.

[0054] If the first terminal cannot successfully parse the first message when it receives both the first message and the second message simultaneously, it can send the first message and the second message separately, i.e., not simultaneously. This allows the first terminal to successfully parse the first message and restore the radio resource service connection based on it. The first message may contain base station access information, thereby instructing the first terminal to restore its connection with that base station. Conversely, if the terminal does not meet this target condition, it can send both the first message and the second message simultaneously.

[0055] This application also provides a method for determining whether a first terminal meets target conditions. The method includes: determining whether the first terminal meets target conditions based on terminal feature data of an abnormal terminal. An abnormal terminal refers to a terminal whose wireless resource service connection has been disconnected, but which meets the target conditions. The method involves matching the first terminal and the abnormal terminal based on their respective terminal feature data. If the matching degree is high, it indicates that the first terminal meets the condition of being an abnormal terminal, i.e., the first terminal meets the target conditions. Specifically, the terminal feature data of the abnormal terminal may include information such as the terminal type, terminal model, and network characteristics. To facilitate obtaining the terminal feature data of abnormal terminals, after detecting abnormal terminals in actual application scenarios, the data of abnormal terminals can be classified, summarized, and stored in an abnormal terminal database. This allows for subsequent determination of whether the current terminal meets the target conditions by retrieving the terminal feature data of abnormal terminals recorded in the database.

[0056] Correspondingly, this application embodiment also provides a method for determining an abnormal terminal, which may include: responding to receiving a connection recovery request information from the terminal's Radio Resource Service; triggering a process of simultaneously transmitting a first message and a second message at the Radio Link Control Protocol layer, and simultaneously sending the first message and the second message to the terminal; if the terminal cannot parse the first message normally, retransmitting the first message to the terminal; if the terminal can parse the retransmitted first message, marking the terminal as an abnormal terminal.

[0057] Specifically, when the base station receives a connection restoration request for Radio Resource Service (RRS) from a terminal, it retransmits the request via the base station's RadioLink Control (RLC). This involves simultaneously retransmitting a first message indicating RRC reconstruction and a second message indicating resolution of terminal contention. If the base station does not receive feedback indicating successful parsing of the first message from the terminal, it means that the terminal could not correctly parse the first message when both messages were sent simultaneously. The base station can then retransmit the first message separately to the terminal after a period of time. If the terminal can parse the retransmitted first message at this time, it is marked as an abnormal terminal.

[0058] Furthermore, in response to the first terminal resuming its connection to the radio resource service, the marking information indicating that the first terminal is an abnormal terminal is deleted. Once the first terminal resumes its connection to the radio resource service, it indicates that the first terminal's RRC reconstruction was successful and it is no longer an abnormal terminal. Therefore, the marking information indicating that it is an abnormal terminal can be deleted; specifically, the marking information indicating that the terminal's radio resource service connection is abnormal can be deleted.

[0059] Because multiple terminals (such as user equipment) may simultaneously initiate random access for different reasons, such as establishing and / or re-establishing a radio control connection (RRC) or obtaining relevant information as needed, and send the same preamble (access channel preamble) in their request to access the base station, these terminals will all send messages carrying their own identification information after receiving the network's random access response. To resolve this conflict, the base station selects to accept one of the terminals and returns a contention resolution message, i.e., returns the second message in the embodiments of this application.

[0060] In one embodiment of this application, the method further includes: in response to receiving random access request information sent by multiple terminals, obtaining access feature information for each terminal; and generating a second message corresponding to the first terminal based on the access feature information, so that the first terminal can access the network element-side device based on the second message. The second message is used to assist the first terminal in avoiding conflicts with other terminals accessing the network element-side device. The terminal's access feature information may include the terminal's identifier, random access preamble, and uplink messages, etc. The second message may carry a contention resolution identifier, so that the terminal can access the base station based on the second message.

[0061] Furthermore, the step of generating a second message corresponding to the first terminal based on access feature information includes: obtaining the cell radio network temporary identifier of the first terminal based on access features; and generating a second message based on the cell radio network temporary identifier, wherein the second message is information including the cell radio network temporary identifier in the media access control layer.

[0062] For example, the second message is a contention-based conflict resolution MACCE. MAC represents the Medium Access Control layer, which controls the order of data transmission on the media, preventing confusion. CE represents the Control Element. MACCE includes the cell radio network temporary identifier. When a user equipment (UE) performs contention-based random access, it can first select a preamble from the resource pool and send it to the base station. Due to the randomness of selection, different UEs may choose the same preamble and send it to the base station, resulting in different UEs receiving the same random access response (RAR) from the base station. Different UEs can use the uplink resources of this uplink grant indication to send message three, leading to random access conflicts between different UEs. To resolve the conflict, different UEs can include a common control channel service data unit (CCCHSDU) in message three and send it to the base station. The CCCHSDU can be used to distinguish between different UEs. After receiving message three from different UEs, the base station selects one of message three to respond to, carrying the CCCH SDU of message three as the medium access control control element (MACCE) in message four, and sends message four to the different UEs. Each UE, upon receiving message four, compares the MACCE with the CCCH SDU in message three. If they match, the random access contention is considered successful; otherwise, the random access contention is considered unsuccessful.

[0063] In this embodiment of the application, during the RRC reconstruction process, the network element-side equipment can identify terminals that cannot correctly parse the RRC reconstruction. When the terminal initiates the RRC reconstruction process again, the network element-side equipment automatically schedules and sends the "Content Contention Resolution MACCE" and "RRC Reconstruction" messages separately. This reduces the probability of the terminal's "RRC Reconstruction" process failing and improves the reconstruction success rate and reconstruction latency of the network element-side equipment. Furthermore, this embodiment of the application provides a flexible solution for handling reconstruction issues. When receiving both "Content Contention Resolution MACCE" and "RRC Reconstruction" messages simultaneously, terminals that can correctly parse the "RRC Reconstruction" message still send both messages simultaneously, avoiding unnecessary increase in base station load.

[0064] The message processing method of this application embodiment will be described below using a specific application scenario, where the network element-side device is a base station. See [link to relevant documentation]. Figure 3This illustration shows a message interaction diagram between a terminal and a base station provided in an embodiment of this application. Figure 3 The specific meanings of each message are as follows:

[0065] Message A: An RRC Reestablishment Request message sent by the terminal to the base station.

[0066] Message B: RRC Reestablishment message sent by the base station to the terminal.

[0067] C message: RRC Reestablishment Complete message sent by the terminal to the base station.

[0068] D message: Contention Conflict Resolution (MACCE) message sent by the base station to the terminal.

[0069] Specifically, the message interaction process is as follows:

[0070] S301, The terminal triggers the reconstruction process and sends an A message to the base station;

[0071] S302. After receiving message A, the base station triggers a retransmission process at the RLC (RadioLink Control) layer that carries both message B and message D, and starts the ACK timer.

[0072] ACK (Acknowledgement character) is a transmission control character sent by the receiving station to the sending station in data communication. It indicates that the received data has been acknowledged as successfully received. In the TCP / IP protocol, if the receiver successfully receives the data, it will reply with an ACK signal.

[0073] The TCP protocol typically includes four types of timers: retransmission timer, persistence timer, keep-alive timer, and time-wait timer. The retransmission timer (RetransmissionTimer) is used throughout the entire connection to handle the Retransmission Timeout (RTO). This timer starts when a packet is sent from the send queue. If an ACK for the packet is received within the RTO, the retransmission timer stops; if the ACK is not received within t >= RTO, the packet is retransmitted, and the retransmission timer is reset. Note: If the ACK packet piggybacks other information, a retransmission timer is not set for that packet.

[0074] S303. The first type of terminal normally parses a retransmission data packet carrying both B and D messages at the RLC layer, returns a retransmission ACK, and sends a C message back to the base station. The second type of terminal cannot normally parse the B and D messages sent simultaneously at the RLC layer and does not provide any feedback.

[0075] S304. The base station did not receive an ACK from the terminal's RLC layer, the ACK timer expired, and a second retransmission was initiated.

[0076] S305, the base station RLC layer sends a second retransmission, the retransmitted data only carries the B message, and the ACK timer is started.

[0077] S306. The second type of terminal normally parses the B message carried in the RLC layer retransmission data packet, returns the retransmission ACK, and sends a C message back to the base station.

[0078] S307. Before the ACK timer expires, the base station receives an ACK from the terminal's RLC layer, confirming the second type of abnormal terminal behavior. If it does not receive the ACK, it triggers the subsequent S301 to S305 procedures.

[0079] S308, Base station side triggers adjustment scheme, starts timer, records CRNTI of terminal accessing cell before timer expires, and marks and stores in abnormal terminal database.

[0080] S309. If a terminal with a marked CRNTI does not initiate a re-access and a re-establishment occurs again, the base station will automatically schedule and send the "Content Contention Resolution (MACCE)" and "RRCReestablishment" messages separately, repeating the process from S301 to S3033.

[0081] The C-RNTI (Cell-RadioNetwork Temporary Identifier) ​​is a dynamic identifier assigned to the UE by the base station. The C-RNTI uniquely identifies a UE under a cell's air interface, and is only valid for UEs in connected mode.

[0082] S310: When a terminal with a calibrated CRNTI reconnects, the base station will delete the original calibration data from the abnormal terminal database in step 8. When the terminal goes through the S301-S306 process again, it will be re-marked and stored in the abnormal terminal database.
