Description

Data processing method and related equipment

Technical Field

The present disclosure relates to the field of communications, and in particular, to a data processing method and related device.

Background

In a communication system, a long term evolution (Long Term Evolution, LTE) network consists of an evolved universal terrestrial radio access network (Evolved Universal Terrestrial Radio Access Network, E-UTRAN), a bearer network, an evolved packet core network (Evolved Packet Core, EPC). Among other things, E-UTRAN is responsible for accessing user traffic, including a large number of evolved base stations (eNodeBs, eNBs). The carrier network is responsible for transmitting data, and may be optical fibers or optical fiber devices. The EPC is responsible for data processing and routing, including mobile management entity (Mobility Management Entity, MME), serving Gateway (S-GW), packet data network Gateway (Packet Data Network Gateway, P-GW), and the like. The UE connects to the eNB through an air interface, and the eNB connects to the EPC through an S1 interface, and the EPC connects to the internet.

When the UE moves between different enbs, the eNB to which the UE is connected may perform handover, specifically, the source eNB to which the UE is connected sends a handover request to the target eNB, and the target eNB may send a handover response message to the source eNB. If the data radio bearer (Data Radio Bearer, DRB) configuration of the target eNB is different from that of the source eNB, the handover response message carries different parameter configurations. After receiving the different parameter configurations sent by the target eNB, the source eNB sends a handover command carrying a full configuration (Full configuration, fullConfig) cell to the UE in order to ensure that the DRB configuration of the UE is consistent with the target eNB, and after receiving the FullConfig cell, the UE reconfigures the DRB configuration of the UE according to the DRB configuration of the target eNB.

However, after receiving the FullConfig cell, the UE directly discards the messages that are not successfully received by the source eNB, where the discarded messages are most likely to be transmission control protocol (Transmission Control Protocol, TCP) link establishment messages or session initiation protocol (Session initialization Protocol, SIP) messages, which affect normal service development of the user, so that the problems of inability to access the internet, voice call failure, large service delay and the like are caused, and the use experience of the user is seriously affected.

Disclosure of Invention

The application provides a data processing method and related equipment, when user equipment receives a switching instruction carrying a Fullconfig cell, the user equipment can retransmit a message which is not successfully received by first access network equipment to second access network equipment.

The first aspect of the present application provides a data processing method, which may be applied to a user equipment. The method comprises the following steps: the user equipment sends a target message to the first access network equipment; the user equipment receives a radio link control protocol (RLC) state report sent by the first access network equipment, wherein the RLC state report is used for indicating the receiving condition of the first access network equipment on a target message; the user equipment receives a target instruction sent by first access network equipment, wherein the target instruction is used for indicating the user equipment to establish connection with second access network equipment, and the target instruction carries full configuration Fullconfig cells; and under the condition that the first access network equipment does not receive the target message, the user equipment sends the target message to the second access network equipment.

The user equipment sends a target message to the first access network device, specifically, a user equipment packet data convergence protocol (Packet Data Convergence Protocol, PDCP) layer receives the target message from an application layer (Application layer), the user equipment PDCP layer processes the received target message and sends the processed target message to a user equipment radio link control protocol (Radio Link Control, RLC) layer, and the user equipment PDCP layer saves the target message after sending the target message. After receiving the target message, the user equipment RLC layer processes the target message and sends the target message to the first access network equipment RLC layer, and the first access network equipment RLC layer continues to send the target message to the upper layer. After receiving the target message sent by the user equipment RLC layer, the first access network equipment RLC layer replies an RLC status report to the user equipment RLC layer. The RLC status report carries information of a target message which is not received by the first access network device, and after the RLC layer of the user equipment parses the RLC status report, the RLC status report can identify the target message which is not received by the first access network device. The user equipment RLC layer transmits the parsing result of the RLC status report to the user equipment PDCP layer.

When the user equipment moves between the first access network equipment and the second access network equipment, the access network equipment connected with the user equipment is switched. Specifically, the first access network device may send a target instruction to the user device, and the user device may switch to the second access network device after receiving the target instruction. If the first access network device and the second access network device are different in configuration, the target command carries a Fullconfig cell, and after receiving the Fullconfig cell, the DRB configuration of the user device is reconfigured according to the DRB configuration of the second access network device. Based on the RLC status report sent by the first access network device, the user device may resend the target packet that is not successfully received by the first access network device to the second access network device.

In the first aspect of the present invention, after receiving a target instruction carrying a Fullconfig cell, the ue retransmits a message that is not successfully received by the first access network device to the second access network device, so as to ensure that a user service can be normally developed as much as possible, avoid the problems that a network cannot be successfully connected, a voice call is not enabled, a service delay is large, and improve the use experience of a user.

In a possible implementation manner of the first aspect, the steps are as follows: the user equipment sends a target message to first access network equipment, which comprises the following steps: the user equipment encrypts the target message; and the user equipment sends the encrypted target message to the first access network equipment. Specifically, the PDCP layer of the ue encrypts the received target message, and sends the target message to the first access network device after the encryption. In addition to the encryption process, the ue may perform an integrity protection process on the target message, which is not limited herein. In the possible implementation manner, the user equipment encrypts the target message, so that the security of the data is improved.

In a possible implementation manner of the first aspect, the steps are as follows: the user equipment sends a target message to the second access network equipment, which comprises the following steps: the user equipment encrypts the target message; and the user equipment sends the target message after encryption processing to the second access network equipment. Specifically, the PDCP layer of the ue may re-encrypt the target packet that is not received by the first access network device, and send the encrypted target packet to the second access network device. In addition to the encryption process, the ue may perform an integrity protection process on the target message, which is not limited herein. In the possible implementation manner, the user equipment encrypts the target message, so that the security of the data is improved.

In a possible implementation manner of the first aspect, the target message is a transmission control protocol TCP chaining message and/or a session initiation protocol SIP message. When the target message is a TCP link establishment message, if the first access network device does not successfully receive the target message and does not resend the target message to the second access network device, the TCP link establishment failure is caused, and therefore the problems of incapability of surfing the internet or large service delay and the like are caused. When the target message is a SIP message, if the first access network device does not successfully receive the target message and does not retransmit the target message to the second access network device, a Long Term Evolution Voice-over-terminal Evolution (VOLTE) cannot call. In the possible implementation manner, the target message is defined as the TCP link establishment message or the SIP message with great influence on the user service, so that the feasibility of the scheme is improved.

In a possible implementation manner of the first aspect, the first access network device and the second access network device are evolved base stations enbs. The eNB is a base station in the fourth Generation mobile communication technology (the 4th Generation mobile communication technology,4G) LTE network, and in addition, the first access network device and the second access network device may be base station nodes (NodeB, NB) in the third Generation mobile communication technology (the 3th Generation mobile communication technology,3G), or next Generation base stations (gNB) in the fifth Generation mobile communication technology (the 5th Generation mobile communication technology,5G). Namely, the data processing method provided by the application can be applied to a 4G network and can also be applied to a 3G network and a 5G network. The first access network equipment is a source base station, and the second access network equipment is a target base station. In the possible implementation manner, the first access network device and the second access network device are limited to be the eNB under the 4G network, so that the feasibility of the scheme is improved.

In a possible implementation manner of the second aspect, the sending unit is specifically configured to encrypt the target packet; and sending the encrypted target message to the first access network equipment.

In a possible implementation manner of the second aspect, the sending unit is specifically configured to encrypt the target packet; and sending the encrypted target message to the second access network equipment.

(1) LTE user plane protocol stack

The LTE user plane is mainly responsible for transmission and processing of service data, and the LTE user plane protocol stack includes a PDCP Layer, an RLC Layer, a media access control Layer (Media Access Control, MAC), and a Physical Layer (PHY) Layer. Among them, the PDCP layer mainly processes radio resource control (Radio Resource Control, RRC) messages from a control plane and internet protocol (Internet Protocol, IP) packets from a data plane, and header compression, decompression, ciphering and deciphering. The RLC layer is responsible for segmentation and concatenation of data, retransmission processing, and sequential transmission of higher layer data. The MAC layer is responsible for handling hybrid automatic repeat request (Hybrid Automatic Repeat reQuest, HARQ) and uplink and downlink scheduling. The physical layer is responsible for handling codec, modem, multi-antenna mapping, and other telecommunication physical layer functions.

(2) LTE control plane protocol stack

The LTE control plane is mainly responsible for coordination and transmission and processing of control signaling, and the LTE control plane protocol stack includes a non-access layer (Non Access Stratum, NAS), an RRC layer, a PDCP layer, an RLC layer, a MAC layer, and a PHY layer. The NAS layer is responsible for handling transmission of information between the ue and the MME, where the content of the transmission may be session management, user management, security management, etc. The NAS layer is transparent to the eNB, the eNB does not have this layer protocol, and in the process that the user equipment sends the NAS message to the MME, the NAS message is only passed to the eNB. The RRC layer is responsible for functions such as connection control, mobility management (handover), etc. The RRC message and the NAS message are control plane messages, transmitted over signaling radio bearers (Signaling Radio Bearer, SRBs). The PDCP layer provides ciphering and integrity protection functions, and RLC and MAC layer functions are identical to those in the user plane.

The protocol stack of LTE can also be divided into L1, L2 and L3 layers. The L1 layer is a physical layer, i.e., PHY layer. The L2 Layer is a Data Link Layer (DLL) Layer including a PDCP Layer, an RLC Layer, and a MAC Layer. The L3 Layer is a Network Layer (NL) including a NAS Layer and an RRC Layer. The L1 Layer, L2 Layer, and L3 Layer are 3 layers in the open system interconnection communication reference model (Open System Interconnection Reference Model, OSI), which are a total of 7 layers, including, in addition to this 3 layers, a Transport Layer (Transport Layer), a Session Layer (Session Layer), a presentation Layer (Presentation Layer), and an application Layer (Application Layer).

(3) Application layer

The application layer is the seventh layer of the seven-layer OSI model. The application layer interfaces directly with the application program and provides common web application services. The application layer is the highest layer of the open system and directly serves the application processes. The method has the function of completing a series of services required by business processing while realizing the mutual communication of a plurality of system application processes. The service elements thereof are divided into two categories, common application service element CASE and specific application service element CASE.

(4) Cell

A cell (cell), also called a cell, refers to an area covered by one of base stations or a part of a base station (sector antenna) in a cellular mobile communication system, in which a mobile station can reliably communicate with the base station through a radio channel.

Referring to fig. 1, fig. 1 is a schematic diagram of a communication network architecture in an embodiment of the present application.

As shown in fig. 1, the communication network includes a plurality of access network devices 101, a plurality of core network devices 102, and a user device 103. The access network device 101 is configured to implement functions such as radio resource scheduling, radio resource management, radio access control, and mobility management, and may be an evolved node b eNB. The core network device 102 is used to provide user connectivity, manage users, and perform bearer for traffic, and may be MME, S-GW, and P-GW. The user equipment 103 may also be called a terminal equipment, and is a device with a wireless transceiving function, and may be deployed on land, including indoor or outdoor, handheld or vehicle-mounted; can also be deployed on the water surface (such as ships, etc.); but may also be deployed in the air (e.g., on aircraft, balloon, satellite, etc.). The user equipment 103 may be an access terminal device, a subscriber unit, a subscriber station, a mobile station, a remote terminal device, a mobile device, a user terminal device, a wireless terminal device, a user agent, or a user equipment. The user device 103 may also be a cellular telephone, a cordless telephone, a session initiation protocol (Session Initiation Protocol, SIP) phone, a wireless local loop (wireless local loop, WLL) station, a personal digital processing (personal digital assistant, PDA) device, a computing device, other processing devices connected to a wireless modem, a wearable device (smart watch, smart bracelet, etc.). The user device 103 may also be a smart furniture (or appliance), a vehicle device in the internet of vehicles (vehicle toeverything, V2X), a customer premise equipment (customer premises equipment, CPE), etc.

The access network devices 101 are connected through an X2 interface, each access network device 101 is connected with a core network device 102 through an S1 interface, and the core network device 102 is connected with the internet. The user equipment 103 is connected to the access network equipment 101 through an air interface (Uu interface), so as to access the internet. The air interface includes a data plane protocol stack and a user plane protocol stack, through which the user equipment 103 may transmit data or signaling.

It will be appreciated that the number of devices in fig. 1 is merely illustrative, and that in practical applications the communication network may include a plurality of access network devices 101, core network devices 102, and user devices 103, and the number of devices is not limited herein.

It should be noted that, in addition to the above description, the communication network is a 4G LTE network, the data processing method provided in the embodiments of the present application may also be applied to a 3G network, for example, a code division multiple access (code divisionmultiple access, CDMA) network or a wideband code division multiple access (wideband code division multiple access, WCDMA) network, and may also be applied to a New Radio (NR) network in 5G. In the embodiment of the present application, a 4G LTE network is taken as an example, and the specific embodiment is not limited herein.

As the user equipment 103 moves between different access network devices, a handover of the access network device to which the user equipment 103 is connected may occur. Specifically, a first access network device connected with the user equipment sends a switching request to a second access network device, and the second access network device sends a switching response message to the first access network device. If the second access network device is different from the first access network device in RLC mode or DRB PDCP/RLC sequence number Size (Serial Number Size, SN Size) configuration, the handover response message will carry different parameter configurations. After receiving the different parameter configurations sent by the second access network, the first access network device sends a handover command carrying a FullConfig cell to the user device 103 in order to ensure that the DRB configuration of the user device 103 is consistent with the second access network device, and the user device processes the handover command according to a 36.300 10.1.2.1.2 protocol after receiving the FullConfig cell, that is, the DRB configuration of the user device reconfigures according to the DRB configuration of the second access network device, however, when the access network device is switched, if there are unsuccessfully sent messages in the messages sent by the user device 103 to the first access network device, the user device 103 directly discards the unsuccessfully sent messages, so that the problems that internet surfing is impossible or voice call is impossible may be caused.

In view of the above problems, embodiments of the present application provide a data processing method. After receiving the switching instruction carrying the FullConfig cell, the user equipment retransmits the message which is not successfully received by the first access network equipment to the second access network equipment. Described in detail below in conjunction with fig. 2.

As shown in fig. 2, an embodiment of a data processing method provided in an embodiment of the present application includes steps 201 to 204.

201. And the user equipment sends the target message to the first access network equipment.

And the user equipment sends a target message to the connected first access network equipment. Specifically, the PDCP layer of the ue receives a target packet from the application layer, processes the target packet, and sends the processed target packet to the RLC layer of the ue. After the PDCP layer of the ue sends the target packet, the target packet is stored. After receiving the target message, the user equipment RLC layer processes the target message and sends the processed target message to the first access network equipment RLC layer, and the first access network equipment RLC layer sends the received target message to the first access network equipment PDCP layer.

202. The first access network device sends an RLC status report to the user device.

After receiving the target message sent by the user equipment RLC layer, the first access network equipment RLC layer replies an RLC status report to the user equipment RLC layer. The RLC status report carries information of a target message which is not received by the first access network device, and after the RLC layer of the user equipment parses the RLC status report, the RLC status report can identify the target message which is not received by the first access network device. The user equipment RLC layer transmits the parsing result of the RLC status report to the user equipment PDCP layer.

203. The first access network equipment sends a target instruction to the user equipment.

The access network device to which the user equipment is connected may be handed over when the user equipment moves between different access network devices or cells. Specifically, the first access network device sends a switching request to the second access network device, the second access network device replies a switching response message, and the first access network device sends a target instruction to the user device, so that the user device switches connection to the second access network device. If the DRB configurations of the first access network device and the second access network device are different, the first access network device may send a target instruction carrying a Fullconfig cell to the user device, where the target instruction may be a handover instruction or a reestablishment instruction. After receiving the target instruction, the user equipment reconfigures the DRB configuration of the user equipment according to the DRB configuration of the second access network equipment, and establishes connection with the second access network equipment after the configuration.

204. And under the condition that the first access network equipment does not receive the target message, the user equipment sends the target message to the second access network equipment.

After receiving the target instruction carrying the Fullconfig cell, the user equipment sends the target message which is not successfully received by the first access network equipment to the second access network equipment again based on the RLC state report replied by the first access network equipment so as to ensure that the user service can be normally developed.

It can be understood that, when the ue receives a handover instruction or a reestablishment instruction that does not carry a Fullconfig cell, the ue will also resend a message that is not successfully received by the first access network device to the second access network device.

If the first access network device has successfully received all the messages sent by the user device, the user device will not send the messages successfully received by the first access network device to the second access network device.

In this embodiment, after receiving the target instruction carrying the Fullconfig cell, the ue resends the message that is not successfully received by the first access network device to the second access network device, so as to ensure that the user service can be normally developed as much as possible, avoid the problems that the network cannot be successfully connected, the voice call is not enabled, the service is not enabled, and the use experience of the user is improved.

Fig. 3 is another embodiment of a data processing method according to the application embodiment. In this embodiment, the user equipment encrypts the target message before sending the target message to the first access network device and the second access network device, which will be described in detail below with reference to fig. 3. As shown in fig. 3, this embodiment includes steps 301 to 307.

301. The PDCP layer of the ue receives the target message.

The user equipment PDCP layer receives an uplink target message from an application layer.

302. The PDCP layer of the ue encrypts the target message.

The PDCP layer of the ue performs ciphering on the received target message, and stores a corresponding plaintext (i.e., an unencrypted target message) after ciphering. In addition to the ciphering process, the user equipment PDCP layer may also perform integrity protection on the target message. Of course, the PDCP layer of the ue may not perform ciphering or integrity protection on the target message, but may directly transfer the target message to a lower layer, which is not limited herein.

303. The user equipment PDCP layer sends the encrypted target message to the user equipment RLC layer.

304. The user equipment RLC layer sends the encrypted target message to the first access network equipment.

The user equipment RLC layer firstly sends the encrypted target message to the first access network equipment RLC layer, and then the first access network equipment RLC layer sends the encrypted target message to the first access network equipment PDCP layer.

305. The first access network device sends an RLC status report to the user device.

After receiving the target message sent by the user equipment RLC layer, the first access network equipment RLC layer replies an RLC status report to the user equipment RLC layer. The RLC status report carries information of a target message which is not received by the first access network device, and after the RLC layer of the user equipment parses the RLC status report, the RLC status report can identify the target message which is not received by the first access network device. The user equipment RLC layer transmits the parsing result of the RLC status report to the user equipment PDCP layer.

After the user equipment obtains the receiving condition of the target message, for the target message which has been successfully received by the first access network equipment, the user equipment deletes the corresponding plaintext (namely deletes the original stored unencrypted target message), and for the target message which has not been received by the first access network equipment, the user equipment does not delete the corresponding plaintext.

306. The first access network device sends a target instruction carrying a Fullconfig cell to the user device.

When the user equipment moves between different access network equipment or cells, handover is triggered, and the first access network equipment sends a target instruction to the user equipment, wherein the target instruction can be a handover instruction or a reestablishment instruction. And the user equipment receives the target instruction sent by the first access network equipment and then switches connection to the second access network equipment. When the configuration of the first access network device is different from that of the second access network device, in order to ensure that the DRB configuration of the user device is the same as that of the second access network device, the target instruction sent by the first access network device to the user device carries a Fullconfig cell, and after the user device receives the Fullconfig cell, the user device reconfigures according to the DRB configuration of the second access network device. When the first access network device and the second access network device are configured identically, the switching instruction or the reestablishing instruction sent by the first access network device to the user device does not carry the Fullconfig cell.

It will be appreciated that, for simplicity and clarity of the drawing, step 306 only depicts that the first access network device sends the target instruction to the RLC layer of the user equipment in fig. 3, and in fact, the target instruction is sent by the L3 layer of the first access network device to the L3 layer of the user equipment, and the RLC layer of the user equipment continues to deliver the target instruction to the upper layer after receiving the target instruction.

307. And the user equipment sends the target message which is not successfully received by the first access network equipment to the second access network equipment.

After receiving the target instruction carrying the Fullconfig cell, the user equipment PDCP layer can re-encrypt the target messages which are stored originally or send the target messages to the second access network device after carrying out integrity protection processing, so as to ensure normal development of user service as much as possible.

It can be understood that, when the ue receives a handover instruction or a reestablishment instruction that does not carry a Fullconfig cell, the ue will also resend a message that is not successfully received by the first access network device to the second access network device.

If the first access network device has successfully received all the target messages sent by the user device, the user device will not send the target messages successfully received by the first access network device to the second access network device.

308. The user equipment PDCP layer sends the received application layer message to the second access network equipment.

And after the user equipment is switched to the second access network equipment, the received application layer message is sent to the second access network equipment.

In this embodiment, after receiving the target instruction carrying the Fullconfig cell, the ue resends the message that is not successfully received by the first access network device to the second access network device, so as to ensure that the user service can be normally developed as much as possible, avoid the problems that the network cannot be successfully connected, the voice call is not successful, the service delay is large, and improve the use experience of the user.
