In order to meet the demands of users for speed, delay, and high-speed mobility of services, a fifth generation (5 g,5th generation) mobile communication technology has emerged. In a 5G network environment, for the purposes of reducing air interface signaling and quickly recovering wireless connection, and quickly recovering data traffic, a radio resource service state is defined, where a radio resource service may include radio resource control (RadioResourceControl, RRC), which is also called Radio Resource Management (RRM) or Radio Resource Allocation (RRA), and means that radio resource management, control and scheduling is performed through a certain policy and means, so that under the condition of meeting the requirement of service quality, limited radio network resources are fully utilized as far as possible, to ensure reaching a planned coverage area, and service capacity and resource utilization rate are improved as far as possible. Taking RRC as an example, the radio resource service states include an RRC INACTIVE (rrc_inactive) state, an RRC IDLE (rrc_idle) state, and an RRC CONNECTED (rrc_connected) state. The purpose of RRC connection reestablishment (rrcconnectionre-establishment) in a 5G (NR) network is to recover the RRC connection that has been previously established. The reason for RRC reestablishment: reconfiguration failure, handover failure, other failures. The network element side message processing method provided by the embodiment of the application is used for solving the problem of the failure of the RRC reestablishment of the terminal.
The method for processing the message at the network element side in the embodiment of the application can be applied to network element side equipment, wherein the network element side equipment can comprise a core network element or a base station, and the core network element can be an access and mobile management function (AccessandMobilityManagementFunction, AMF), a mobile management entity (MobilityManagementEntity, MME) and the like. Referring to fig. 1, a schematic diagram of a communication system is provided in an embodiment of the present application, in the communication system, a network element side device is denoted by a base station 101, a terminal is denoted by a user equipment 102 (UserEquipment, UE), in fig. 1, N UEs are included, and the number of specific user equipments UE may be determined according to an actual application scenario.
The following describes a method for processing a network element side message according to an embodiment of the present application, referring to fig. 2, the method may include the following steps:
s201, receiving a connection restoration request message of the radio resource service sent by the first terminal.
S202, if the first terminal is detected to meet the target condition, a first message and a second message are respectively sent to the first terminal, so that the first terminal resumes connection of the radio resource service.
The first message is a connection recovery message of the radio resource service, and the second message is a terminal contention conflict resolution message. The target condition characterizes that the first terminal can not successfully analyze the condition of the first message when receiving the first message and the second message at the same time.
The Radio resource service may include Radio resource control, radio resource management, radio resource scheduling, radio resource allocation, etc., and is described by taking Radio resource control (Radio ResourceControl, RRC) as an example for convenience of description in the embodiment of the present application. The purpose of RRC connection reestablishment (RRC connection) in a 5G network is to recover the previously established RRC connection. The reason for RRC reestablishment: reconfiguration failure, handover failure, other failures. Therefore, when the terminal needs to recover the RRC connection that has been established before, a connection recovery request message of the radio resource service (e.g. RRC) is sent to the network element side device (e.g. base station).
When the network element side equipment (such as a base station) receives a connection recovery request message of a radio resource service (such as RRC) sent by the first terminal. The network element side device detects whether the first terminal meets the target condition, namely, determines that the connection recovery request of the radio resource service cannot be successfully resolved when the first terminal receives the connection recovery request of the radio resource service and the terminal contention conflict resolution message.
When the first terminal cannot successfully analyze the first disappearance when receiving the first message and the second message at the same time, the first terminal can respectively send the first message and the second message to the first terminal, namely, the first message and the second message are not sent at the same time, so that the first terminal can successfully analyze the first message, and the connection of the radio resource service is restored based on the first message. The first message may contain access information for the base station, indicating that the first terminal may resume the connection with the base station. Correspondingly, if the terminal does not meet the target condition, the first message and the second message can be sent to the terminal at the same time.
The embodiment of the application also provides a method for determining whether the first terminal meets the target condition, which comprises the following steps: based on the terminal characteristic data of the abnormal terminal, whether the first terminal meets the target condition is determined. The abnormal terminal is a terminal with disconnected wireless resource service connection and meets the target condition, the first terminal and the abnormal terminal are matched based on the terminal characteristic data of the first terminal and the terminal characteristic data of the abnormal terminal, and if the matching degree is higher, the condition that the first terminal meets the abnormal terminal is indicated, namely, the first terminal is determined to meet the target condition. Specifically, the terminal characteristic data of the abnormal terminal may include information such as a type of the terminal, a model of the terminal, a network characteristic of the terminal, and the like. In order to facilitate obtaining the terminal characteristic data of the abnormal terminal, after the abnormal terminal is detected in the actual application scene, the data of the abnormal terminal can be classified and summarized, and the abnormal terminal database is stored, so that whether the current terminal meets the target condition can be determined by obtaining the terminal characteristic data of the abnormal terminal recorded in the abnormal terminal database.
Correspondingly, in the embodiment of the application, a method for determining an abnormal terminal is also provided, and the method can comprise the following steps: responding to the received connection restoration request information of the wireless resource service of the terminal; triggering a processing flow for simultaneously transmitting a first message and a second message in a radio link control protocol layer, and simultaneously transmitting the first message and the second message to the terminal; if the terminal cannot normally analyze the first message, retransmitting the first message to the terminal; and if the terminal can analyze the retransmitted first message, marking the terminal as an abnormal terminal.
Specifically, when the base station receives the connection restoration request information of the radio resource service of the terminal, the base station retransmits the connection restoration request information through the base station side RLC (radio link control), that is, the first message indicating RRC reestablishment and the second message indicating resolving the contention conflict of the terminal are retransmitted at the RLC layer at the same time. When the base station does not receive the feedback information of the first message successfully analyzed by the terminal, the terminal can not analyze the first message normally when the first message and the second message are simultaneously sent to the terminal. Then, the base station may resend the first message to the terminal separately after a period of time, and if the terminal can parse the resent first message at this time, mark the terminal as an abnormal terminal.
Further, in response to the first terminal restoring the connection of the radio resource service, the tag information of the first terminal being the abnormal terminal is deleted. After the first terminal resumes the connection of the radio resource service, it indicates that the first terminal RRC reestablishes successfully, and does not belong to an abnormal terminal, and further the tag information characterizing that the first terminal is an abnormal terminal may be deleted, for example, specifically, the tag information that the radio resource service connection of the terminal is abnormal may be deleted.
Since there may be multiple terminals (e.g., user equipment) that are simultaneously initiating random access based on different reasons, such as establishing and/or reestablishing a radio control connection (RRC), or acquiring related information based on demand. And the same preamble (preamble of access channel) is sent in the message of requesting access to the base station, and after receiving the random access response of the network, the terminals all send the message carrying their own identification information. To resolve this conflict, the base station chooses to admit one of the terminals and returns the message as a contention resolution message, i.e. the second message in the embodiment of the application.
In one implementation of the embodiment of the present application, the method further includes: obtaining access characteristic information of each terminal in response to receiving random access request information sent by a plurality of terminals; and generating a second message corresponding to the first terminal based on the access characteristic information so that the first terminal can access network element side equipment based on the second message. The second message is used for assisting the first terminal to avoid collision with other terminal random access network element side equipment. The access characteristic information of the terminal may include an identity of the terminal, a random access preamble, an uplink message, and the like. The second message may carry a contention conflict resolution identification such that the terminal accesses the base station based on the second message.
Further, the generating, based on the access characteristic information, a second message corresponding to the first terminal includes: based on the access characteristic, obtaining a cell wireless network temporary identifier of the first terminal; and generating a second message according to the cell wireless network temporary identifier, wherein the second message is information comprising the cell wireless network temporary identifier in the media access control layer.
For example, the second message is a contention conflict resolution MACCE, where the MAC characterizes a medium access control layer (medium access control), including controlling who issues first and then issues when data is sent to the medium, i.e. preventing confusion. CE characterizes the control element (control element). The MACCE includes a cell radio network temporary identity. When a User Equipment (UE) performs contention-based random access, a preamble may be first selected from a resource pool and transmitted to a base station. Due to the randomness of the selection, different UEs may select the same preamble to send to the base station, so that the different UEs receive the same Random Access Response (RAR) sent by the base station. Different UEs can send a message III by using the uplink resource indicated by the uplink grant, which can cause random access conflict of different UEs. To resolve the collision, different UEs may send common control channel service data units (CCCHSDUs) carried in message three to the base station, and the CCCHSDUs may be used to distinguish between the different UEs. After receiving the message three sent by different UEs, the base station selects and responds to one of the messages three, carries the CCCH SDU of the message three as a control unit (MACCE) of a medium access control layer in a message four, and sends the message four to different UEs. After each UE in different UEs receives the message IV, the MACCE is compared with the CCCHSDU in the message III, if the MACCE is consistent with the CCCHSDU, the random access competition is determined to be successful, and if the MACCE is inconsistent with the CCCHSDU, the random access competition is determined to be failed.
In the embodiment of the application, in the RRC reestablishment process, the network element side equipment can identify the terminal incapable of normally analyzing the RRC reestablishment, and when the terminal initiates the RRC reestablishment process next time, the network element side equipment automatically dispatches and sends the 'competition conflict resolution MACCE' and the 'RRC reestablishment' message separately. The probability of failure of the RRC reestablishment process of the terminal can be reduced, and the reestablishment success rate and reestablishment delay indexes of the network element side equipment are improved. In addition, the scheme for processing the reestablishment problem is flexible, and when the 'contention conflict resolution MACCE' and the 'RRC reestablishment' messages are received simultaneously, the terminal which can normally analyze the 'RRC reestablishment' messages still adopts the 'contention conflict resolution MACCE' and the 'RRC reestablishment' messages to transmit simultaneously, so that the unnecessary base station load is avoided being increased.
The message processing method of the embodiment of the application is described below with specific application scenarios, where the network element side device is a base station. Referring to fig. 3, a message interaction diagram between a terminal and a base station according to an embodiment of the present application is shown. In fig. 3, the specific meaning of each message is as follows:
a message: the terminal sends an RRC reestablishment request message to the base station (RRCReestablishment Request).
And B, message: the base station sends an RRC reestablishment message (RRCReestablishment) to the terminal.
And C, message: the terminal sends an RRC reestablishment complete message to the base station (RRCReestablishment Complete).
And D, message: and the base station resolves the MACCE message for the competition conflict sent by the terminal.
Specifically, the message interaction flow is as follows:
s301, triggering a reestablishment flow by a terminal, and sending an A message to a base station;
s302, after receiving the A message, the base station triggers a flow of retransmitting the B message and the D message and starts an ACK timer in an RLC (radio Link control) layer.
Wherein ACK (Acknowledgecharacter) is an acknowledgement character, a transmission class control character that the receiving station sends to the sending station in data communication. Indicating that the transmitted data has been acknowledged with no errors. In the TCP/IP protocol, if the receiver successfully receives data, an ACK data is replied.
The TCP protocol typically includes 4 timers: retransmission timer, duration timer, keep-alive timer, and time waiting timer. Retransmission timer: the retransmission timer is used for the entire connection period for handling RTO (retransmission timeout). After a message is sent out of the send queue. The timer is started. If the ACK of the message is received in the RTO, stopping the retransmission timer; if t > =rto has not received ACK for the message, the message is retransmitted and the retransmission timer is reset. Note that: if the ACK message carries other information, a retransmission timer is not set for the message.
S303, the first type terminal normally analyzes a retransmission of the RLC layer and carries the data packet of the B message and the D message, returns retransmission ACK, and feeds back the C message to the base station, and the second type terminal cannot normally analyze the B message and the D message which are transmitted by the RLC layer and have no feedback.
S304, the base station side does not receive the ACK sent by the terminal RLC layer to the base station, the ACK timer is overtime, and secondary retransmission is started.
S305, the base station RLC layer sends secondary retransmission, retransmission data only carries B information, and an ACK timer is started.
S306, the second type terminal normally analyzes the B message carried by the retransmission data packet of the RLC layer, returns retransmission ACK, and feeds back the C message to the base station.
S307, the base station side receives the ACK sent by the terminal RLC layer to the base station before the ACK timer is overtime, and confirms the abnormal behavior of the second type terminal. If not, the continuous flow of S301 to S305 is triggered.
S308, triggering an adjustment scheme by the base station side, starting a timer, recording CRNTI of the access cell terminal before the timer is overtime, and storing the mark into an abnormal terminal database.
S309, when re-accessing is not initiated by the terminal marked with CRNTI, and re-establishing occurs again, the base station automatically dispatches and sends the 'MACCE' and the 'RRCReessablight' messages separately, and the processes of S301-S3033 are repeated.
The Cell-radio network temporary identifier (C-RNTI) is a dynamic identifier allocated to the UE by the base station. The C-RNTI uniquely identifies the UE under the air interface of one cell, and is valid only for the UE in the connected state.
S310, the terminal calibrated with CRNTI is accessed again, and the base station side deletes the original calibration data in the original 8 th step abnormal terminal database. After the terminal again takes place the flow of S301 to S306, the new flag is stored in the abnormal terminal database.
