In order to realize the conversion of these two bearer forms, in The 3rd Generation Partnership Project (3GPP), the reconfiguration of PDCP is realized through radio resource control (RRC) connection reconfiguration (Connection reconfiguration) signaling. Specifically, the base station sends RRCconnectionreconfiguration, indicating that it is used for PDCP version conversion; at the same time, after the base station sends the signaling, it converts the versions of its own PDCP sending entity (DL) and PDCP receiving entity (UL); the user equipment After (UserEquipment, UE) receives the RRCconnectionreconfiguration, it converts the versions of its own PDCP sending entity (UL) and PDCP receiving entity (DL); the user equipment replies to the RRC connection reconfiguration complete signaling (RRCconnectionreconfigurationComplete), which uses the conversion The later PDCP version is sent, and the base station can receive because the PDCP version has been converted at this time.

Detailed ways

FIG. 1 is a schematic diagram of an application scenario of an embodiment of the present invention.

As shown in FIG. 1 , an application scenario of the embodiment of the present invention may include a terminal device 110 and a network device 120 . The network device 120 may communicate with the terminal device 110 through the air interface. Multi-service transmission is supported between the terminal device 110 and the network device 120 .

The radio bearer on the network device 120 has a Packet Data Convergence Protocol (PDCP) entity, and the PDCP entity may have multiple versions. For example, the lower layer of the PDCP entity of the LTE version is the Radio Link Layer Control (Radio Link Control, RLC) and the Media Access Control (Media Access Control, MAC) layer of the LTE version. For another example, in the PDCP entity of the New Radio (NR) version, the lower layer thereof is the RLC and MAC of the LTE version.

It should be understood that the PDCP entity of the LTE version and the PDCP entity of the NR version described above are only exemplary descriptions of the PDCP entity version. The embodiments of the present invention are not limited to this. For example, the versions of PDCP entities on network device 120 may include PDCP entity versions used by various communication systems. It should also be understood that the embodiments of the present invention are only exemplified by a 5G system, but the embodiments of the present invention are not limited thereto. That is, the technical solutions of the embodiments of the present invention can be applied to various communication systems.

For example, the communication systems involved in the embodiments of the present invention include, but are not limited to: a Global System of Mobile communication (GSM) system, a Code Division Multiple Access (Code Division Multiple Access, CDMA) system, and a Wideband Code Division Multiple Access (Wideband Code) system. Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (Long Term Evolution, LTE) system, LTE Time Division Duplex (TDD), Universal Mobile Communication System (Universal Mobile Telecommunication System, UMTS), etc.

Therefore, in order to realize the handover of the PDCP entity among multiple versions, 3GPP proposes to reconfigure the PDCP through radio resource control connection reconfiguration (RRCConnectionreconfiguration) signaling.

More specifically, referring to FIG. 1, the network device 120 sends the RRCconnectionreconfiguration to the terminal device 110, indicating that the terminal device 110 performs PDCP version conversion; at the same time, after the network device 120 sends the signaling, it sends its own PDCP sending entity. (DL) and PDCP receiving entity (UL) versions are converted. In other words, after the terminal device 110 receives the RRCconnectionreconfiguration, it converts the versions of its own PDCP sending entity (UL) and PDCP receiving entity (DL). The converted PDCP version is sent, and the network device 120 can receive it because the PDCP version conversion has been performed at this time.

It can be found that in the above process, after the network device 120 issues the RRCconnectionreconfiguration, before the terminal device 110 replies with RRCconnectionreconfigurationComplete, the terminal device 110 may also send the uplink signaling to the network device 120 with the PDCP version before conversion.

However, since the network device 120 has already converted the versions of its own PDCP sending entity (DL) and PDCP receiving entity (UL) after sending the signaling, in the face of the uplink signaling sent with the PDCP version before the conversion, the network Device 120 cannot receive normally.

Therefore, in view of the above technical problems, the present invention proposes a method for controlling terminal equipment to generate uplink signaling, so that the terminal equipment stops the generated uplink signaling before the network equipment 120 performs PDCP version switching, thereby improving the success rate of data transmission .

Therefore, the network device 120 can confirm that the terminal device 110 has no uplink data in the buffer (buffer) of the signaling radio bearers (SRB), thereby preventing the terminal device 110 from replying to RRCconnectionreconfigurationComplete after receiving the RRCconnectionreconfiguration. The uplink signaling sent by the PDCP version before the conversion is sent to the network device. This increases the success rate of data transmission.

It should be understood that applying the method for controlling a terminal device to generate uplink signaling provided in the embodiment of the present invention to the scenario of PDCP version switching is only an exemplary description, and is not specifically limited in the embodiment of the present invention. That is to say, the method in the embodiment of the present invention can be applied to any scenario where it is necessary to control a terminal device to generate uplink signaling.

Furthermore, the present invention describes various embodiments in conjunction with network equipment and terminal equipment.

The network device 120 may refer to any entity on the network side that is used to send or receive signals. For example, it can be a user equipment of machine type communication (MTC), a base station (Base Transceiver Station, BTS) in GSM or CDMA, a base station (NodeB) in WCDMA, an evolved base station (Evolutional Node B, eNB or eNodeB) in LTE ), network equipment in 5G networks, etc.

The terminal device 110 may be any terminal device. Specifically, the terminal device 110 may communicate with one or more core networks (Core Network) via a radio access network (Radio Access Network, RAN), and may also be referred to as an access terminal, user equipment (User Equipment, UE), Subscriber unit, subscriber station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent or user equipment. For example, it may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a wireless communication capability handheld devices, computing devices or other processing devices connected to wireless modems, in-vehicle devices, wearable devices, and end devices in 5G networks.

FIG. 2 is a schematic flowchart of a method 200 for controlling a terminal device to generate uplink signaling according to an embodiment of the present invention.

As shown in Figure 2, the method 200 includes:

210. The terminal device is in a state of generating the first uplink signaling.

220. Under the first condition, the terminal equipment stops generating the first uplink signaling; wherein, the first condition refers to a condition that needs to be satisfied when the terminal equipment stops generating the first uplink signaling. That is, the terminal device is in a state of stopping generating the first uplink signaling.

In other words, the terminal equipment in the state of generating the first uplink signaling stops generating the first uplink signaling when the first condition is satisfied. Therefore, when the terminal device or the network device needs the terminal device to stop generating uplink signaling, the terminal device can be effectively controlled to stop generating the first uplink signaling (for example, when the network device needs to switch the version of the PDCP entity).

It should be understood that the first uplink signaling in this embodiment of the present invention may be at least one kind of uplink signaling that is preconfigured, or at least one kind of uplink signaling determined through negotiation between the terminal device and the network device. The embodiments of the present invention are not specifically limited.

For example, the first uplink signaling may include all uplink signaling that can be generated by the terminal device.

For another example, the first uplink signaling may include: among all the uplink signaling that the terminal device can generate, the uplink signaling except the second uplink signaling, the first uplink signaling and the second uplink signaling Let be different uplink signaling. Further, the second uplink signaling may include radio resource control RRC connection request signaling (RRCConnectionSetupRequest) and/or RRC connection setup completion signaling (RRCConnectionSetupComplete), and the RRC connection request signaling is used to request the network device to establish an RRC connection. , the RRC connection establishment complete signaling is used to instruct the network device to establish a connection between the network device and the core network device according to the RRC connection establishment complete signaling. In other words, the first uplink signaling may include uplink signaling other than RRC connection request signaling and RRC connection establishment completion signaling.

For another example, the first uplink signaling may include specific uplink signaling among all uplink signaling that the terminal device can generate. Further, the specific uplink signaling may include sidelink (Sidelink UEInformation) information, where the sidelink information is used to indicate sidelink related information of the terminal device.

The first condition of the embodiment of the present invention is exemplarily described below.

As an optional embodiment, before the terminal device establishes the signaling radio bearer SRB2 or the data radio bearer, it stops generating the first uplink signaling.

As an optional embodiment, the terminal device stops generating the first uplink signaling after receiving the first indication information sent by the network device, and the first indication information is used to instruct the terminal device to stop generating the first uplink signaling signaling.

As an optional embodiment, after the terminal device sends second indication information to the network device, it stops generating the first uplink signaling, and the second indication information is used to indicate that the terminal device is in a state of stopping generating the first uplink signaling. order status.

It should be noted that, in this embodiment of the present invention, in a scenario where a terminal device or a network device requires the terminal device to stop generating the first uplink signaling, the terminal device may stop generating the first uplink signaling under the first condition signaling. Therefore, the above-mentioned scenario in which the terminal device stops generating the first uplink signaling is only an exemplary description, and the embodiment of the present invention is not limited thereto.

Further, when the terminal device or the network device needs the terminal device to switch to a state where the first uplink signaling can continue to be generated, the terminal device can switch back to a state where the first uplink signaling can continue to be generated.

Therefore, in the embodiment of the present invention, a method for controlling the terminal equipment to continue to generate the first uplink signaling is also provided.

Optionally, the terminal device can continue to generate the first uplink signaling under a second condition; wherein the second condition refers to a condition that needs to be satisfied when the terminal device can continue to generate the first uplink signaling.

For example, after the terminal device establishes the signaling radio bearer SRB2 or the data radio bearer, it may continue to generate the first uplink signaling.

For another example, after the terminal device receives the sending third indication information sent by the network device, it can continue to generate the first uplink signaling, and the third indication information is used to indicate that the terminal device can continue to generate the first uplink signaling . In other words, after the network device sends the third indication information to the terminal device, it is used to indicate that the terminal device can continue to generate the first uplink signaling.

For another example, after the terminal device sends the fourth indication information to the network device, it can continue to generate the first uplink signaling, and the fourth indication information is used to indicate that the terminal device is in a state where it can continue to generate the first uplink signaling .

It should be understood that the above situation is only an exemplary description of the first uplink signaling in the embodiment of the present invention, which is not specifically limited in the embodiment of the present invention. It should also be understood that the terms first indication information and second indication information may be used in the embodiments of the present invention, but these indication information should not be limited to these terms. These terms are only used to distinguish indication information from one another.

In addition, it should be noted that the method for controlling a terminal device to generate uplink signaling in this embodiment of the present invention can be applied to any scenario where it is necessary to control a terminal device to stop or continue to generate uplink signaling.

The method for controlling and controlling a terminal device to generate uplink signaling according to an embodiment of the present invention is exemplarily described below by taking an application scenario where the network device needs to switch the version of the PDCP entity as an example. Specifically, in the process of the version of the PDCP entity by the network device, in order to improve the success rate of data transmission, the network device needs to determine that the terminal device has no uplink data in the buffer of the signaling radio bearer (SRB).

In this embodiment of the present invention, it is assumed that a first SRB exists between a network device and a terminal device, the first SRB has a first PDCP entity, and versions of the first PDCP entity include a first version and a second version, the first version and The second versions are versions of PDCP entities used by different communication systems respectively, the first version is different from the second version, and the version currently used by the first PDCP entity is the first version. The network device may switch the version of the first PDCP entity from the first version to the second version when the terminal device determines that there is at least no first uplink signaling in the buffer of the first SRB.

For example, the terminal device stops generating the first uplink signaling before establishing the second SRB, and the first SRB is different from the second SRB; then the network device may The version is switched from the first version to the second version.

For another example, the terminal device stops generating the first uplink signaling before establishing the data radio bearer DRB; then the network device may switch the version of the first PDCP entity from the first version to the second version before establishing the DRB Version.

For another example, before the version of the first PDCP entity is switched from the first version to the second version, the network device may send first indication information to the terminal device, where the first indication information is used to instruct the terminal device to stop The first uplink signaling is generated; after receiving the response message of the first indication information sent by the terminal device, the network device can switch the version of the first PDCP entity from the first version to the second version.

For another example, the network device may switch the version of the first PDCP entity from the first version to the second version after receiving the second indication information sent by the terminal device, where the second indication information is used to indicate the The terminal device is in a state of stopping generating the first uplink signaling.

Further, after the version of the first PDCP entity is switched from the first version to the second version, the network device or the terminal device can control the terminal device to switch from the state of stopping generating the first uplink signaling to the second version. The state of the first uplink signaling may continue to be generated.

For example, the network device can send third indication information to the terminal device, where the third indication information is used to indicate that the terminal device can continue to generate the first uplink signaling; further, the network device can pass the first PDCP entity's The second version receives the first uplink signaling sent by the terminal device.

For another example, the network device may receive fourth indication information sent by the terminal device, where the fourth indication information is used to indicate that the terminal device is in a state where the first uplink signaling can be generated; The second version of a PDCP entity receives the first uplink signaling sent by the terminal device.
