Description

Technical Field

[0001] The present application belongs to the field of wireless communication technology, and specifically relates to a network connection processing method, a terminal, and a network-side device. Background Art

[0002] Relay technology in wireless communication systems refers to adding one or more relay nodes between the base station and the terminal, which is responsible for forwarding the wireless signal once or multiple times, that is, the wireless signal has to go through multiple hops to reach the terminal.

[0003] Wireless relay technology can not only be used to expand cell coverage and fill in cell coverage blind spots, but also to increase cell capacity through spatial resource reuse. For indoor coverage, Relay technology can also overcome penetration loss and improve indoor coverage quality.

[0004] Taking a simpler two-hop relay as an example, a wireless relay can split a base station-terminal link into two links: base station-relay station and relay station-terminal. This provides an opportunity to replace a poor quality link with two good quality links to obtain higher link capacity and better coverage.

[0005] The relay currently supported in LTE is UE-to-Network relay, that is, one end of the relay is connected to the UE and the other end is connected to the network. The UE connected to the relay is called remote UE.

[0006] In the relay scenario, the Remote UE can establish an indirect path or a direct path with the network side device. The indirect path refers to the wireless link that the Remote UE establishes an RRC connection with the base station through the Relay UE and the Uu air interface of the Relay UE. The direct path refers to the wireless link that the Remote UE establishes an RRC connection with the base station through its own Uu air interface.

[0007] However, the related art does not provide a specific technical solution for the Remote UE to establish an indirect connection path, which may result in the remote UE being unable to effectively establish an indirect connection path in some scenarios. Summary of the invention

[0049] Figure 1a A block diagram of a wireless communication system applicable to an embodiment of the present application is shown. The wireless communication system includes a relay terminal 11, a network side device 12, and a remote terminal 13. In the embodiment of the present application, the remote terminal 13 can establish a wireless link of an RRC connection with the network side device 12 through the relay terminal 11 and the Uu air interface of the relay terminal 11, and the remote terminal 13 can also establish a wireless link of an RRC connection with the network side device 12 through the Uu air interface of the remote terminal 13.

[0050] Among them, the relay terminal 11 can also be called a relay terminal device or a relay user terminal (User Equipment, UE), the remote terminal 13 can also be called a remote terminal device or a remote UE, the relay terminal 11 and the remote terminal 13 can be a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (Laptop Computer) or a notebook computer, a personal digital assistant (Personal Digital Assistant, PDA), a handheld computer, a netbook, an ultra-mobile personal computer (ultra-mobile personal computer, UMPC), a mobile Internet device (Mobile Internet Device, MID), a wearable device (Wearable Device) or a vehicle-mounted device (VUE), a pedestrian terminal (PUE) and other terminal side devices, and the wearable device includes: a bracelet, a headset, glasses, etc. It should be noted that the specific types of the relay terminal 11 and the remote terminal 13 are not limited in the embodiment of the present application. The network side device 12 can be a base station or a core network, wherein the base station can be referred to as a node B, an evolved node B, an access point, a base transceiver station (Base TransceiverStation, BTS), a radio base station, a radio transceiver, a basic service set (Basic Service Set, BSS), an extended service set (Extended Service Set, ESS), a B node, an evolved B node (eNB), a home B node, a home evolved B node, a WLAN access point, a WiFi node, a transmitting and receiving point (Transmitting Receiving Point, TRP) or some other suitable term in the field. As long as the same technical effect is achieved, the base station is not limited to a specific technical vocabulary. It should be noted that in the embodiment of the present application, only the base station in the NR system is taken as an example, but the specific type of the base station is not limited.

[0051] The core network equipment may include but is not limited to at least one of the following: core network node, core network function, mobility management entity (Mobility Management Entity, MME), access mobility management function (Access and Mobility Management Function, AMF), session management function (Session Management Function, SMF), user plane function (User Plane Function, UPF), policy control function (Policy Control Function, PCF), policy and charging rules function unit (Policy and Charging Rules Function, PCRF), edge application service discovery function (Edge Application Server Discovery Function, EASDF), unified data management (Unified Data Management, UDM), unified data storage (Unified Data Repository, UDR), home user server (Home Subscriber Server, HSS), centralized network configuration (CNC), network storage function (Network Repository Function, NRF), network exposure function (Network Exposure Function, NEF), local NEF (Local NEF, or L-NEF), binding support function (Binding Support Function, BSF), application function (Application Function, AF), etc. It should be noted that in the embodiments of the present application, only the core network device in the NR system is introduced as an example, and the specific type of the core network device is not limited.

[0052] Figure 1b A typical UE-to-Network scenario in the related art is shown, such as Figure 1b As shown in the figure, in this scenario, the Remote UE needs to transmit data with the network side, but due to poor coverage, it finds the Relay UE to transfer the data. The interface between the Relay UE and the base station is the Uu interface, and the interface between the Relay UE and the Remote UE is the sidelink (PC5) interface. Generally speaking, the Relay UE is open and can serve any Remote UE.

[0053] In addition, in the related technology, multipath scenarios are also involved. For example, for the sidelink relay architecture, such as Figure 2a to Figure 2c As shown in Figure 1, multipath means that the Remote UE establishes both indirect path and direct path. For non-sidelink relay architecture, the connection between two UEs is not a sidelink (PC5) interface, such as Figure 3a to Figure 3c As shown, the interface between the two UEs can be a wired connection or an ideal inter-UE connection. The multipath refers to the Primary UE (with Figure 2a to Figure 2c The remote UE role in the UE is equivalent to that in the UE that establishes both the indirect path and the direct path.

[0054] It can be seen that the indirect path in the related technology refers to the wireless link that the Remote UE (or Primary UE) establishes an RRC connection with the base station through the Relay UE (or Secondary UE) and the Uu air interface of the Relay UE (or Secondary UE). The direct path refers to the wireless link that the Remote UE (or Primary UE) establishes an RRC connection with the base station through its own Uu air interface.

[0055] In the vehicle mobile scenario, Figure 4 As shown, the smartphone (remote UE) is connected to the smart cockpit (relay UE) of the car via wifi or Bluetooth, and a non-direct connection path is established with the network side device (gNB) through the Uu air interface of the smart cockpit (relay UE), thereby realizing the UL / DL data transmission of the smartphone. However, the smartphone itself can also establish a direct connection path with the network side device through its Uu air interface. Therefore, under what circumstances the smartphone communicates with the network side device through a non-direct connection path is a technical problem that needs to be solved in the relevant technology. To address this problem, the implementation embodiment of this application provides a network connection processing method, terminal and network side device.

[0056] The following, in conjunction with the accompanying drawings, describes in detail the network connection processing method, terminal and network side device provided in the embodiments of the present application through some embodiments and their application scenarios.

[0057] It should be noted that the relay terminal in the embodiment of the present application may be a relay terminal supporting 3GPP access technology, a relay terminal supporting non-3GPP access technology, or a relay terminal supporting 3GPP access technology and non-3GPP access technology. In the subsequent embodiments, only one or more types of terminals are used for exemplary description, but relay terminals supporting different access technologies can be replaced with each other in each embodiment.

[0058] Figure 5 A flowchart of a method for processing a network connection in an embodiment of the present application is shown. The method 500 can be executed by a remote terminal. In other words, the method can be executed by software or hardware installed on the remote terminal. Figure 5 As shown, the method may include the following steps.

[0059] S510: The remote terminal determines that a condition for establishing an indirect path is met.

[0060] In an embodiment of the present application, the remote terminal can determine whether the conditions for establishing a non-direct path are met when determining information to be transmitted when in a non-connected state, or the remote terminal can determine whether the conditions for establishing a non-direct path are met when in a connected state.

[0061] In an optional implementation of the embodiment of the present application, the indirect path establishment condition may include at least one of the following:

[0062] (1) The current mobility state of the Remote UE is a preset state, and the preset state may include at least one of the following: a high-mobility state and a medium-mobility state. The mobility state of the Remote UE may be divided into three categories: a high-mobility state, a medium-mobility state, and a normal-mobility state. Therefore, the high-mobility state and the medium-mobility state may also be defined as non-Normal-mobility states; the medium-mobility state and the low-mobility state may also be defined as non-High-mobility states.

[0063] Optionally, the remote terminal may determine the current mobile state of the remote terminal based on the number of times the cell reselection occurs within the duration. For example, when the number of times the cell reselection occurs within the duration of the remote terminal is greater than a first counting threshold, the remote terminal determines that the mobile state of the remote terminal is a high-speed mobile state; when the number of times the cell reselection occurs within the duration of the remote terminal is less than or equal to the first counting threshold, and greater than or equal to a second counting threshold, the remote terminal determines that the mobile state of the remote terminal is a medium-speed mobile state, wherein the first counting threshold is greater than the second counting threshold; when the number of times the cell reselection occurs within the duration of the remote terminal is less than the second counting threshold, the remote terminal determines that the mobile state of the remote terminal is a normal mobile state.

[0064] Optionally, the duration, the first counting threshold and the second counting threshold may be detection parameters sent by the serving base station of the remote terminal. For example, the serving base station broadcasts a set of detection parameters to the Remote UE, and the set of parameters includes: CRmax ,N CR_H ,N CR_M If the Remote UE determines that the CRmax The number of cell reselections within a period is greater than N CR_H , it is determined that the conditions for the high-mobility state are met and the high-mobility state is entered. CRmax The number of cell reselections within a period is less than or equal to N CR_H , and greater than or equal to N CR_M , then it is determined that the conditions for the medium-mobility state are met and the medium-mobility state is entered. CRmax The number of cell reselections within is less than N CR_M , it is determined that the conditions for the normal mobility state are met and the normal mobility state is entered.

[0065] (2) The Remote UE prefers to establish, restore or reestablish a connection with the network side device through an indirect path, such as an RRC connection. For example, the Remote UE may determine whether it prefers to establish, restore or reestablish a connection with the network side device through an indirect path based on at least its own moving speed, remaining battery power, uplink wireless capability, and other factors.

[0066] (3) The Remote UE obtains the first indication information sent by the network side device, and the first indication information indicates that the remote terminal is supported or allowed to establish a non-direct connection path with the network side device through the relay terminal.

[0067] In the embodiment of the present application, the remote terminal can communicate with the relay terminal through non-3GPP wireless access technology (for example, wifi, infrared communication or Bluetooth communication technology). In this case, the relay terminal is referred to as non-3GPP RelayUE.

[0068] In an embodiment of the present application, the first indication information sent by the above-mentioned network side device may be sent by the network side device through a system information block (System Information Block, SIB). For example, the Remote UE obtains the SIB message of its serving base station, and the SIB message carries the first indication information of whether to support or allow the establishment of a non-direct path between the non-3GPP Relay UE and the serving base station. When the first indication information indicates that the establishment of a non-direct path between the non-3GPP Relay UE and the serving base station is supported or allowed, it is judged that the condition for establishing the non-direct path is met. In this case, the Remote UE regards the serving base station of the Relay UE as its own serving base station.

[0069] (4) The remote terminal obtains auxiliary information of the relay terminal, and the auxiliary information includes at least one of the following: the Uu connection status of the relay terminal is available, and indication information that the relay terminal plays a relay role.

[0070] For example, the Remote UE obtains the auxiliary information of the non-3GPP Relay UE, and the auxiliary information includes the Uu connection status of the Relay UE and the indication information of whether the Relay UE acts as a relay UE. If the Uu connection status of the Relay UE in the auxiliary information is available and the indication information indicates that the Relay UE acts as a relay, it is determined that the non-direct path establishment condition is met.

[0071] Among them, the Uu connection state of the above-mentioned Relay UE is available, which may mean that the Relay UE is currently in the RRC connected state, or the Relay UE is currently in the RRC non-connected state, but the RSRP quality of the serving cell (PCell or Serving Cell) of the Relay UE is higher than the preset threshold, that is, the Uu channel condition of the Relay UE is good.

[0072] In the related art, the remote UE and the relay UE have a sidelink (Sidelink) / PC5 air interface, and can trigger a non-direct path establishment process based on the discovery (discovery) and relay selection or reselection (re)selection) functions of the Sidelink / PC5, but does not support non-3GPP interfaces such as WiFi and Bluetooth between UEs. The above-mentioned solution provided in the embodiment of the present application can realize the establishment of a non-direct path based on a non-3GPP relay for the scenario of non-3GPP relay.

[0073] In addition, for the scenario where the remote UE and relay UE have a sidelink / PC5 air interface, the Uu reference signal received power (RSRP) of the remote UE's service cell being lower than a certain threshold can be used as a trigger condition for establishing an indirect path. However, in some scenarios, such as the above-mentioned vehicle communication scenario, if only the Uu RSRP of the service cell of the remote terminal is used to determine whether to establish a non-direct path, it may not meet the actual needs. For example, if the remote terminal is in a high-speed mobile state, the Uu RSRP of its service cell may be high, but since the remote terminal is in a high-speed mobile state, if a direct path with the network-side device is established, it may cause the remote terminal to frequently switch between cells. For another example, the remote terminal may determine that it is inclined to establish a non-direct path with the network-side device based on factors such as its own moving speed, remaining power, and uplink wireless capability, but the Uu RSRP of the service cell of the remote terminal may not be lower than the preset threshold. If the Uu RSRP of the service cell is still used to determine whether to establish a non-direct path, it is obviously not able to meet the needs of the remote terminal. Therefore, in the embodiment of the present application, in the above cases (1) to (4), it is determined that the indirect path establishment condition is met.

[0074] S512, the remote terminal initiates a first target process through the relay terminal.

[0075] In an embodiment of the present application, the first target process includes any one of the following:

[0076] RRC connection establishment process;

[0077] RRC connection recovery process;

[0078] RRC connection reestablishment process.

[0079] For example, if the remote terminal is currently in a non-connected state, the remote terminal can initiate an RRC connection establishment process or an RRC connection recovery process through the relay terminal, and send an RRC connection establishment request message or an RRC connection recovery request message to the Relay UE, and the RRC connection establishment request message or the RRC connection recovery request message is forwarded to the network side device through the Relay UE. If the remote terminal is currently in an RRC connected state, the remote terminal can initiate an RRC connection reestablishment process through the relay terminal, and send an RRC connection reestablishment request message to the Relay UE, and the RRC connection reestablishment request message is forwarded to the network side device through the Relay UE.

[0080] The above-mentioned technical solution provided by the embodiment of the present application can support the scenario of remote terminal access with limited uplink capability, and can be applicable to scenarios such as high-speed movement in vehicles by means of relay terminals communicating with the network.

[0081] In an optional implementation, in order to enable the network side device to know the reason why the remote terminal communicates through a non-direct connection path, after S512, the method may also include the following steps: the remote terminal sends the target information of the remote terminal to the network side device through the relay terminal, wherein the target information includes at least one of the following: the mobile status of the remote terminal, and the remote terminal tends to maintain only a non-direct connection path.

[0082] In an optional implementation, the remote terminal can send one of the following messages carrying the target information to the network side device through the relay terminal during the execution of the first target process: RRC connection establishment completion message, RRC connection recovery completion message, and RRC connection reconstruction completion message.

[0083] Alternatively, in another optional implementation, after completing the first target process, the remote terminal may also send a target message carrying the target information to the network side device through the relay terminal, and the target message includes one of the following: relay link terminal information (SidelinkUEInformation) message, terminal assistance information (UEAssitanceInformation) message, and an RRC message dedicated to sending the target information.

[0084] In an optional implementation, the method may further include: when it is determined that the non-direct path establishment condition is not met, the remote terminal initiates a second target process through the Uu air interface, wherein the second target process includes any one of the following:

[0085] RRC connection establishment process;

[0086] RRC connection recovery process;

[0087] RRC connection reestablishment process.

[0088] In the above implementation, when the indirect path establishment condition is not met, the remote terminal may initiate the second target process through the Uu air interface to ensure communication between the remote terminal and the network side device.

[0089] For example, if the remote terminal is currently in a non-connected state, the remote terminal can initiate an RRC connection establishment process or an RRC connection recovery process through the Uu air interface, and send an RRC connection establishment request message or an RRC connection recovery request message to the network side device. If the remote terminal is currently in an RRC connection state through a non-direct connection path, the remote terminal can initiate an RRC connection reestablishment process through the Uu air interface, and send an RRC connection reestablishment request message to the network side device.

[0090] Optionally, in the above implementation, in order to enable the network side device to know the state or tendency of the remote terminal, after the remote terminal initiates the second target process through the Uu air interface, the remote terminal may send the target information of the remote terminal to the network side device through the Uu air interface, wherein the target information includes at least one of the following: the mobile state of the remote terminal, and the tendency of the remote terminal to only maintain a non-direct connection path.

[0091] In one implementation, the remote terminal may, during the process of executing the second target process, send one of the following messages carrying the target information to the network side device through the Uu air interface: an RRC connection establishment completion message, an RRC connection recovery completion message, or an RRC connection reconstruction completion message.

[0092] In another implementation, after completing the second target process, the remote terminal can send a target message carrying the target information to the network side device through the Uu air interface, and the target message includes one of the following: a relay link terminal information message, a terminal auxiliary information message, and an RRC message dedicated to sending the target information.

[0093] Optionally, after receiving the target information of the remote terminal, the network side device may instruct the remote terminal to switch. Therefore, after completing the second target process, the method may also include: the remote terminal receives a switching indication sent by the network side device, wherein the switching indication is used to instruct the remote terminal to communicate with the network side device through a non-direct path. Based on the switching indication, the remote terminal can switch to a non-direct path to communicate with the network side device, that is, communicate with the network side device through a relay terminal, for example, communicate with the network side device through a non-3GPP Relay UE.

[0094] Optionally, corresponding to the above-mentioned condition for satisfying the indirect path establishment condition, the condition for not satisfying the indirect path establishment condition includes at least one of the following:

[0095] (1) The movement state of the remote terminal is not a preset state, wherein the preset state includes at least one of the following: a high-speed movement state and a medium-speed movement state;

[0096] For example, if the number of times the remote terminal reselects a cell within the duration is less than the second counting threshold, and the remote terminal is in a normal moving state, it is determined that the indirect path establishment condition is not met.

[0097] (2) the remote terminal does not tend to establish, restore or reestablish a connection with the network-side device through an indirect path;

[0098] For example, the Remote UE may determine that it is not inclined to establish, restore or reestablish a connection with a network side device through an indirect path based at least on its own moving speed, remaining power, uplink wireless capability and other factors, and thus determine that the indirect path establishment condition is not met.

[0099] (3) the remote terminal fails to obtain the first indication information sent by the network side device;

[0100] For example, if the SIB sent by the network side device does not carry the first indication information indicating whether to support or allow the establishment of an indirect path between the non-3GPP RelayUE and the serving base station, it is determined that the indirect path establishment condition is not met.

[0101] (4) The remote terminal obtains first indication information sent by the network side device, and the first indication information sent by the network side device indicates that the remote terminal is not supported or is not allowed to establish a non-direct connection path with the network side device through the relay terminal;

[0102] For example, the SIB sent by the network side device carries first indication information indicating whether to support or allow the establishment of a non-direct path between the non-3GPP Relay UE and the service base station, and the first indication information indicates that the establishment of a non-direct path between the non-3GPP Relay UE and the service base station is not supported or allowed, then it is determined that the condition for establishing the non-direct path is not met.

[0103] (5) The remote terminal fails to obtain the auxiliary information of the relay terminal;

[0104] For example, if the remote terminal fails to obtain the auxiliary information of the relay terminal through a connection interface such as Wi-Fi or Bluetooth with the relay terminal, it is determined that the condition for establishing the indirect connection path is not met.

[0105] (6) The remote terminal obtains the auxiliary information of the relay terminal, and the obtained auxiliary information includes at least one of the following: the Uu connection status of the relay terminal is unavailable, and the second indication information that the relay terminal does not play the role of a relay. For example, the remote terminal obtains the auxiliary information of the relay terminal through a connection interface such as wifi or Bluetooth with the relay terminal, but the obtained auxiliary information contains the second indication information that the Uu connection status of the relay terminal is unavailable or the relay terminal does not play the role of a relay, then it is determined that the indirect path establishment condition is not met.

[0106] Among them, the Uu connection state of the relay terminal is unavailable, which may be that the Uu port of the relay terminal is in a non-RRC connected state, or the relay terminal is in an RRC non-connected state and the RSRP of its serving cell is lower than a preset threshold, that is, the Uu channel condition of the Relay UE is poor, or the relay terminal is in an RRC connected state and a wireless link failure occurs in its serving cell.

[0107] Through the above-mentioned implementation method, when the conditions for establishing a non-direct connection path are not met, the remote terminal can initiate the second target process through the Uu air interface, establish communication with the network side device, and notify the network side device of the mobility status of the remote terminal or the tendency to maintain only the non-direct connection path, so that the network side device can obtain the mobility status or tendency of the remote terminal, and then instruct the remote terminal to switch to the non-direct connection path.

[0108] Figure 6 A flow chart of the information sending method in the embodiment of the present application is shown, and the method 600 can be executed by a remote terminal. In other words, the method can be executed by software or hardware installed on the remote terminal. Figure 6 As shown, the method may include the following steps.

[0109] S610, the remote terminal sends the target information of the remote terminal to the network side device through the relay terminal or the Uu air interface, wherein the target information includes at least one of the following: the mobility status of the remote terminal, and the remote terminal's tendency to maintain only a non-direct connection path.

[0110] In the embodiment of the present application, the remote terminal may send the above target information to the network side device through the relay terminal (i.e., the non-direct path) to notify the mobile state of the remote terminal or the tendency to maintain only the non-direct path. Alternatively, the remote terminal may also send the above target information to the network side device through the Uu air interface (i.e., the direct path) to notify the mobile state of the remote terminal or the tendency to maintain only the non-direct path, so that the network side device can know the mobile state of the remote terminal or the tendency to maintain only the non-direct path.

[0111] In one implementation, the remote terminal may send an RRC connection establishment completion message or an RRC connection recovery completion message or an RRC connection reconstruction completion message carrying the target information to the network side device through a relay terminal or a Uu air interface during the process of executing the third target process, wherein the third target process includes any one of the following: an RRC connection establishment process, an RRC connection recovery process, and an RRC connection reconstruction process. For example, the remote terminal may initiate the third target process through a relay terminal, send an RRC connection establishment request message or an RRC connection recovery request message or an RRC connection reconstruction request message to the network side device, and after receiving a response from the network side device, send an RRC connection establishment completion message or an RRC connection recovery completion message or an RRC connection reconstruction completion message carrying the target information to the network side device. Alternatively, the remote terminal can initiate a third target process through the Uu air interface, send an RRC connection establishment request message or an RRC connection recovery request message or an RRC connection reconstruction request message to the network side device, and after receiving a response from the network side device, send an RRC connection establishment completion message or an RRC connection recovery completion message or an RRC connection reconstruction completion message carrying the target information to the network side device.

[0112] In another implementation, after completing the third target process, the remote terminal may send a target message carrying the target information to the network side device through a relay terminal or a Uu air interface, and the target message includes one of the following: a relay link terminal information message, a terminal auxiliary information message, and an RRC message dedicated to sending the target information, wherein the third target process includes any one of the following: an RRC connection establishment process, an RRC connection recovery process, and an RRC connection reconstruction process.

[0113] In an optional implementation, the remote terminal may send the target information of the remote terminal to the network side device through a relay terminal or a Uu air interface when determining that the condition for establishing a non-direct connection path is not met.

[0114] Optionally, similar to the above method 500, not satisfying the indirect path establishment condition includes at least one of the following:

[0115] (1) The movement state of the remote terminal is not a preset state, wherein the preset state includes at least one of the following: a high-speed movement state and a medium-speed movement state;

[0116] For example, if the number of times the remote terminal reselects a cell within the duration is less than the second counting threshold, and the remote terminal is in a normal moving state, it is determined that the indirect path establishment condition is not met.

[0117] (2) the remote terminal does not tend to establish, restore or reestablish a connection with the network-side device through an indirect path;

[0118] For example, the Remote UE may determine that it is not inclined to establish, restore or reestablish a connection with a network side device through an indirect path based at least on its own moving speed, remaining power, uplink wireless capability and other factors, and thus determine that the indirect path establishment condition is not met.

[0119] (3) the remote terminal fails to obtain the first indication information sent by the network side device;

[0120] For example, if the SIB sent by the network side device does not carry the first indication information indicating whether to support or allow the establishment of an indirect path between the non-3GPP RelayUE and the serving base station, it is determined that the indirect path establishment condition is not met.

[0121] (4) The remote terminal obtains first indication information sent by the network side device, and the first indication information sent by the network side device indicates that the remote terminal is not supported or is not allowed to establish a non-direct connection path with the network side device through the relay terminal;

[0122] For example, the SIB sent by the network side device carries first indication information indicating whether to support or allow the establishment of a non-direct path between the non-3GPP Relay UE and the service base station, and the first indication information indicates that the establishment of a non-direct path between the non-3GPP Relay UE and the service base station is not supported or allowed, then it is determined that the condition for establishing the non-direct path is not met.

[0123] (5) The remote terminal fails to obtain the auxiliary information of the relay terminal;

[0124] For example, if the remote terminal fails to obtain the auxiliary information of the relay terminal through a connection interface such as Wi-Fi or Bluetooth with the relay terminal, it is determined that the condition for establishing the indirect connection path is not met.

[0125] (6) The remote terminal obtains the auxiliary information of the relay terminal, and the obtained auxiliary information includes at least one of the following: the Uu connection status of the relay terminal is unavailable, and the second indication information that the relay terminal does not play the role of a relay. For example, the remote terminal obtains the auxiliary information of the relay terminal through a connection interface such as wifi or Bluetooth with the relay terminal, but the obtained auxiliary information contains the second indication information that the Uu connection status of the relay terminal is unavailable or the relay terminal does not play the role of a relay, then it is determined that the indirect path establishment condition is not met.

[0126] The unavailable Uu connection state of the relay terminal may be that the Uu port of the relay terminal is in a non-connected state, or that the Uu port of the relay terminal is in a non-connected state and the service quality of the serving cell is lower than a preset threshold, that is, the service quality is poor.

[0127] Optionally, after receiving the target information of the remote terminal, if the remote terminal currently sends the target information through a relay terminal, the network side device may instruct the remote terminal to maintain a non-direct connection path. If the remote terminal currently sends the target information through a Uu air interface, the network side device may instruct the remote terminal to switch. Therefore, after the remote terminal sends the target information of the remote terminal to the network side device through a relay terminal or a Uu air interface, the method may further include: the remote terminal receives a switching indication sent by the network side device, wherein the switching indication is used to instruct the remote terminal to communicate with the network side device through a non-direct connection path. Based on the switching indication, the remote terminal can switch to a non-direct connection path to communicate with the network side device, that is, communicate with the network side device through a relay terminal, for example, communicate with the network side device through a non-3GPP Relay UE.

[0128] Through the above method provided in the embodiment of the present application, the remote terminal can send the above target information to the network side device through the relay terminal or the Uu air interface, so that the network side device can learn the mobility status or tendency of the remote terminal, and then determine whether to establish a direct path or an indirect path with the remote terminal based on the mobility status or tendency of the remote terminal, and is not limited to being triggered by the RSRP of the Uu air interface of the remote terminal, thereby being able to adapt to the access scenario of the remote terminal with limited uplink capability.

[0129] Figure 7 A flow chart of a method for obtaining information in an embodiment of the present application is shown. The method 700 can be executed by a network-side device. In other words, the method can be executed by software or hardware installed on the network-side device. Figure 7 As shown, the method may include the following steps.

[0130] S710, a network side device receives target information of a remote terminal sent by the remote terminal through a relay terminal or a Uu air interface, wherein the target information includes at least one of the following: a mobile state of the remote terminal, and a tendency of the remote terminal to maintain only a non-direct connection path.

[0131] Method 700 is a network-side device execution method corresponding to method 600. The remote terminal can send the target information in the manner described in method 600. For details, please refer to the relevant description in the above method 600, which will not be repeated here.

[0132] In an optional implementation, after receiving the target information of the remote terminal, if the remote terminal currently sends the target information through the relay terminal, the network side device may instruct the remote terminal to maintain a non-direct path. If the remote terminal currently sends the target information through the Uu air interface, the network side device may instruct the remote terminal to switch. Therefore, after the network side device receives the target information of the remote terminal sent by the remote terminal through the relay terminal or the Uu air interface, the method may also include: the network side device sends a switching indication to the remote terminal through the relay terminal or the Uu air interface, wherein the switching indication is used to instruct the remote terminal to communicate with the network side device through a non-direct path. Through this implementation, under the premise that a direct path exists, by reporting the target information of the remote UE to the base station, it is possible to switch to a non-direct path based on the Relay UE, and under the premise that a non-direct path exists, by reporting the target information of the remote UE to the base station, it is possible to maintain a non-direct path based on the Relay UE.

[0133] In an optional implementation, before S710, the method may further include: the network side device sends a detection parameter, wherein the detection parameter includes: the duration, a first counting threshold and a second counting threshold, and the first counting threshold is greater than the second counting threshold. The remote terminal may determine the mobile state of the remote terminal based on the detection parameter, and the details may refer to the relevant description in the above method 500, which will not be repeated here.

[0134] The following describes the technical solution provided in the embodiment of the present application through a specific implementation method using a non-3GPP relay scenario.

[0135] Figure 8 Another flowchart of the method for processing a network connection provided by an embodiment of the present application is shown as follows: Figure 8 As shown, the method may include the following steps:

[0136] Step 801: The Remote UE receives a SIB message sent by a base station, or the Remote UE receives auxiliary information of a non-3GPP Relay UE sent by a relay terminal.

[0137] This step is optional.

[0138] Step 802: The Remote UE determines whether a condition for establishing an indirect path is met.

[0139] For example, the Remote UE is in the RRC idle state (RRC_IDLE) or the RRC inactive state (RRC_INACITVE). At this time, there is service data or signaling to be transmitted, so it is necessary to trigger the RRC connection establishment process or the RRC connection recovery process to establish or restore the connection with the base station, and the Remote UE determines whether the indirect path establishment condition is met.

[0140] Specifically, the Remote UE may determine whether the following conditions are met:

[0141] Condition 1: Whether the current mobility state of the Remote UE meets the preset state. When the Remote UE detects that its current mobility state is a high-mobility state or a medium-mobility state, it is determined that condition 1 is met.

[0142] Among them, the remote UE can detect its current mobility state in the following ways:

[0143] The serving base station broadcasts a set of detection parameters to the Remote UE, which includes: T CRmax ,N CR_H ,N CR_M .

[0144] If the Remote UE determines that the CRmax The number of cell reselections within a period is greater than N CR_H , it is determined that the conditions for the high-mobility state are met and the high-mobility state is entered.

[0145] If the Remote UE determines that the CRmax The number of cell reselections within a period is less than or equal to N CR_H , and greater than or equal to N CR_M , it is determined that the conditions for the medium-mobility state are met and the medium-mobility state is entered.

[0146] If the Remote UE determines that the CRmax The number of cell reselections within is less than N CR_M , it is determined that the conditions for the normal mobility state are met and the normal mobility state is entered.

[0147] Condition 2: Whether the Remote UE prefers to establish or restore the RRC connection via an indirect path. If the Remote UE prefers to establish or restore the RRC connection via an indirect path, it is determined that Condition 2 is met.

[0148] Among them, the tendency of the Remote UE may be the result of at least considering various factors such as its own moving speed, remaining power, uplink wireless capability, etc., and the specific algorithm is not limited in the embodiments of the present application.

[0149] Condition 3: The Remote UE obtains a SIB message from the serving base station, and the SIB message carries first indication information on whether to support or allow the establishment of a non-direct path between the serving base station and the non-3GPP Relay UE. When the first indication information indicates that the establishment of a non-direct path between the serving base station and the non-3GPP Relay UE is supported or allowed, it is determined that Condition 3 is met.

[0150] Condition 4: The Remote UE obtains auxiliary information of the non-3GPP Relay UE, and the auxiliary information includes the Uu connection status of the Relay UE or the second indication information of whether the Relay UE is acting as a relay UE. If the Uu connection status of the Relay UE in the auxiliary information is available or the second indication information indicates acting as a relay UE, it is determined that Condition 4 is met.

[0151] Step 803: Under the premise that at least one of the above conditions 1 to 4 is met, the remote terminal sends an RRC connection establishment request message or an RRC connection recovery request message to the non-3GPP Relay UE, and the RRC connection establishment request message or the RRC connection recovery request message is forwarded to the base station through the non-3GPP Relay UE.

[0152] Step 804: the remote terminal receives an RRC connection establishment message or an RRC connection recovery message sent by the base station, and the RRC connection establishment message or the RRC connection recovery message is forwarded to the Remote UE via the non-3GPP Relay UE.

[0153] Step 805: The remote terminal sends an RRC connection establishment complete message or an RRC connection recovery complete message to the non-3GPP Relay UE, and the RRC connection establishment complete message or the RRC connection recovery complete message is forwarded to the base station via the non-3GPP Relay UE.

[0154] The RRC connection establishment completion message or the RRC connection recovery completion message in step 805 may carry remote UE related information, and the remote UE related information includes at least one of the following: the current mobility state of the Remote UE; and the tendency of the Remote UE to maintain only a non-direct connection path.

[0155] Alternatively, the RRC connection establishment complete message or the RRC connection recovery complete message in step 805 may not carry the above remote UE related information, and the method may further include step 806.

[0156] Step 806: The remote terminal sends a SidelinkUEInformation (SUI) message or a UEAssitanceInformation (UAI) message or a new RRC message to the non-3GPP Relay UE, and the SidelinkUEInformation message or the UEAssitanceInformation message or the new RRC message is forwarded to the base station through the non-3GPP Relay UE, and the SidelinkUEInformation message or the UEAssitanceInformation message or the new RRC message carries remote UE related information, and the remote UE related information includes at least one of the following: the current mobility status of the Remote UE; the Remote UE's tendency to maintain only a non-direct path.

[0157] Fig. 9 Another flowchart of the method for processing a network connection provided by an embodiment of the present application is shown as follows: Fig. 9 As shown, the method may include the following steps:

[0158] Step 901 is the same as step 801.

[0159] Step 902: The Remote UE determines whether a condition for establishing an indirect path is met.

[0160] Specifically, the Remote UE may determine whether the following conditions are met:

[0161] Condition 1: Whether the current mobility state of the Remote UE meets the preset state. When the Remote UE detects that its current mobility state is a normal mobility state or a non-high-mobility state, it is determined that condition 1 is not met.

[0162] Condition 2: Whether the Remote UE prefers to establish or restore the RRC connection through an indirect path. When the Remote UE prefers to establish or restore the RRC connection through a direct path or not through an indirect path, it is determined that Condition 2 is not satisfied.

[0163] Among them, the Remote UE tendency may be the result of at least considering various factors such as its own moving speed, remaining power, uplink wireless capability, etc., and the specific algorithm is not limited in the embodiments of the present application.

[0164] Condition 3: The Remote UE obtains the SIB message of the serving base station in step 901. When the SIB message does not carry the first indication information of whether to support or allow the establishment of a non-direct path between the non-3GPP Relay UE and the serving base station, or carries the first indication information, and the first indication information indicates that the establishment of a non-direct path between the non-3GPP Relay UE and the serving base station is not supported or is prohibited, it is judged that condition 3 is not met.

[0165] Condition 4: The Remote UE obtains the auxiliary information of the non-3GPP Relay UE in step 801, and when the auxiliary information does not include the Uu connection status of the Relay UE or the second indication information of whether the Relay UE is acting as a relay UE, or includes the Uu connection status of the Relay UE or the second indication information but the Uu connection status of the Relay UE is unavailable or the second indication information indicates that the Relay UE is not acting as a relay UE, it is judged that Condition 4 is not met.

[0166] Step 903: When at least one of the above conditions 1 to 4 is not met, the remote terminal directly sends an RRC connection establishment request message or an RRC connection recovery request message to the base station through the Uu air interface.

[0167] Step 904: The remote terminal directly receives the RRC connection establishment message or the RRC connection recovery message sent by the base station through the Uu air interface.

[0168] Step 905: The remote terminal directly sends an RRC connection establishment completion message or an RRC connection recovery completion message to the base station through the Uu air interface.

[0169] The RRC connection establishment completion message or the RRC connection recovery completion message may carry remote UE related information, and the remote UE related information includes at least one of the following: the current mobility state of the Remote UE; and the tendency of the Remote UE to maintain only a non-direct connection path.

[0170] Alternatively, the RRC connection establishment complete message or the RRC connection recovery complete message may not carry remote UE related information, and the method may further include step 906, otherwise, execute step 907.

[0171] Step 906: Send a SidelinkUEInformation message or a UEAssitanceInformation message or a new RRC message directly through the Uu air interface, wherein the SidelinkUEInformation message or the UEAssitanceInformation message or the new RRC message carries remote UE related information, and the remote UE related information includes at least one of the following: the current mobility status of the Remote UE; the tendency of the Remote UE to maintain only a non-direct path.

[0172] Step 907: The remote terminal directly receives the RRC reconfiguration message sent by the base station through the Uu air interface, where the RRC reconfiguration message carries path switching configuration information instructing the remote UE to switch to a non-direct path based on a non-3GPP relay.

[0173] Step 908: The remote terminal performs a path switching operation according to the path switching configuration information in step 907, and sends an RRC reconfiguration completion message to the non-3GPP Relay UE, and the RRC reconfiguration completion message is forwarded to the base station via the non-3GPP Relay UE.

[0174] Fig.10 Another flowchart of the method for processing a network connection provided by an embodiment of the present application is shown as follows: Fig.10 As shown, the method may include the following steps:

[0175] Step 1001: The remote terminal performs cell selection and reselection according to the Uu mechanism, selects a suitable cell, and directly sends an RRC connection establishment request message or an RRC connection recovery request message to the base station through the Uu air interface.

[0176] Step 1002: The remote terminal directly receives an RRC connection establishment message or an RRC connection recovery message sent by the base station through the Uu air interface.

[0177] Step 1003: The remote terminal directly sends an RRC connection establishment completion message or an RRC connection recovery completion message to the base station through the Uu air interface.

[0178] The RRC connection establishment completion message or the RRC connection recovery completion message may carry remote UE related information, and the remote UE related information includes at least one of the following: the current mobility state of the Remote UE; and the tendency of the Remote UE to maintain only a non-direct connection path.

[0179] Alternatively, the RRC connection establishment complete message or the RRC connection recovery complete message may not carry remote UE related information, and the method may further include step 1004, otherwise, directly execute step 1005.

[0180] Step 1004: The remote terminal directly sends a SidelinkUEInformation message or a UEAssitanceInformation message or a new RRC message through the Uu air interface, wherein the SidelinkUEInformation message or the UEAssitanceInformation message or the new RRC message carries information related to the remote UE, and the information related to the remote UE includes at least one of the following: the current mobility status of the Remote UE; the tendency of the Remote UE to maintain only a non-direct path.

[0181] Step 1006: The remote terminal directly receives an RRC reconfiguration message sent by the base station through the Uu air interface, where the RRC reconfiguration message carries path switching configuration information instructing the remote UE to switch to a non-direct path based on a non-3GPP relay.

[0182] Step 1007: The remote terminal performs a path switching operation according to the path switching configuration information in step 1006, and sends an RRC reconfiguration completion message to the non-3GPP Relay UE, and the RRC reconfiguration completion message is forwarded to the base station via the non-3GPP Relay UE.

[0183] The technical solution provided in the embodiment of the present application can support scenarios where terminals with limited uplink capabilities access the network by means of non-3GPP relays, and is suitable for high-speed vehicle-mounted mobile scenarios.

In the embodiment of the present application, the network connection processing device provided in the embodiment of the present application is described by taking the network connection processing method executed by the network connection processing device as an example.
