[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the China Patent Office on September 7, 2023, with application number 202311157305.9 and invention name “Network connection processing method, terminal and network side device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0003] 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

[0004] 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. In other words, the wireless signal has to go through multiple hops before reaching the terminal.

[0005] Wireless relay technology not only expands cell coverage and fills blind spots, but also increases cell capacity through spatial resource reuse. For indoor coverage, relay technology can also overcome penetration loss and improve indoor coverage quality.

[0006] 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 the opportunity to replace one poor-quality link with two high-quality links, thereby achieving higher link capacity and better coverage.

[0007] Currently, the relay supported in LTE is a UE-to-network relay, meaning 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 a remote UE.

[0008] In a relay scenario, the Remote UE can establish an indirect path or a direct path with the network-side device. An indirect path refers to a radio link in which the Remote UE establishes an RRC connection with the base station through the Relay UE and the Relay UE's Uu air interface. A direct path refers to a radio link in which the Remote UE establishes an RRC connection with the base station through its own Uu air interface.

[0009] 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 the indirect connection path in some scenarios.

[0052] Figure 1a shows a block diagram of a wireless communication system applicable to embodiments of the present application. The wireless communication system includes a relay terminal 11, a network-side device 12, and a remote terminal 13. In embodiments of the present application, the remote terminal 13 can establish an RRC-connected wireless link with the network-side device 12 via the relay terminal 11 and the Uu air interface of the relay terminal 11. Furthermore, the remote terminal 13 can also establish an RRC-connected wireless link with the network-side device 12 via the Uu air interface of the remote terminal 13.

[0053] The relay terminal 11 may also be referred to as a relay terminal device or a relay user equipment (UE), and the remote terminal 13 may also be referred to as a remote terminal device or a remote UE. The relay terminal 11 and the remote terminal 13 may be terminal-side devices such as a mobile phone, a tablet personal computer, a laptop computer or a notebook computer, a personal digital assistant (PDA), a handheld computer, a netbook, an ultra-mobile personal computer (UMPC), a mobile internet device (MID), a wearable device or a vehicle-mounted device (VUE), a pedestrian terminal (PUE), etc. Wearable devices include: 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 embodiments of the present application.

[0055] Figure 1b illustrates a typical UE-to-network scenario in related art. In this scenario, a remote UE needs to transmit data to the network. However, due to poor coverage, it uses a relay UE to relay the data. The Uu interface connects the relay UE to the base station, while the sidelink (PC5) interface connects the relay UE to the remote UE. Generally speaking, the relay UE is open and can serve any remote UE.

[0056] In addition, related technologies also involve multipath scenarios. For example, for a sidelink relay architecture, as shown in Figures 2a to 2c, multipath means that the Remote UE establishes both an indirect path and a direct path. For a non-sidelink relay architecture, that is, the connection between the two UEs is not a sidelink (PC5) interface, as shown in Figures 3a to 3c, the interface between the two UEs can be a wired connection or an ideal inter-UE connection. Multipath means that the Primary UE (equivalent to the remote UE role in Figures 2a to 2c) establishes both an indirect path and a direct path.

[0057] As can be seen from this, the indirect path in the related art refers to the radio link in which 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 radio link in which the Remote UE (or Primary UE) establishes an RRC connection with the base station through its own Uu air interface.

[0058] In the in-vehicle mobile scenario, as shown in Figure 4, a smartphone (remote UE) is connected to the car's smart cockpit (relay UE) via Wi-Fi or Bluetooth, and establishes a non-direct connection path with the network-side device (gNB) through the Uu air interface of the smart cockpit (relay UE), thereby enabling 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, the technical problem that needs to be solved in the relevant technology is under what circumstances the smartphone communicates with the network-side device through a non-direct connection path. To address this problem, the embodiments of the present application provide a network connection processing method, terminal, and network-side device.

[0059] 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.

[0060] It should be noted that the relay terminal in the embodiments of the present application may be a relay terminal that supports 3GPP access technology, a relay terminal that supports non-3GPP access technology, or a relay terminal that supports both 3GPP access technology and non-3GPP access technology. The subsequent embodiments will be described using only one or more types of terminals as examples, but relay terminals supporting different access technologies may be interchangeable in the embodiments.

[0061] FIG5 is a flow chart illustrating a method for processing a network connection according to an embodiment of the present application. 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. As shown in FIG5 , the method may include the following steps.

[0062] S510: The remote terminal determines that a condition for establishing an indirect path is met.

[0063] 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 the 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.

[0064] In an optional implementation of the embodiment of the present application, the indirect path establishment condition may include at least one of the following:

[0065] (1) The current mobility state of the Remote UE is a preset state, which may include at least one of the following: a high-mobility state and a medium-mobility state. The mobility state of the Remote UE can 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 can also be defined as non-normal-mobility states; the medium-mobility state and the low-mobility state can also be defined as non-high-mobility states.

[0066] Optionally, the remote terminal may determine the current mobility state of the remote terminal based on the number of cell reselections that occur within the duration. For example, if the number of cell reselections that occur within the duration for the remote terminal is greater than a first counting threshold, the remote terminal determines that the mobility state of the remote terminal is a high-speed mobility state; if the number of cell reselections that occur within the duration for 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 mobility state of the remote terminal is a medium-speed mobility state, wherein the first counting threshold is greater than the second counting threshold; if the number of cell reselections that occur within the duration for the remote terminal is less than the second counting threshold, the remote terminal determines that the mobility state of the remote terminal is a normal mobility state.

[0067] 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: T CRmax ,N CR_H ,N CR_M If the Remote UE determines that the CRmax The number of cell reselections that occur 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 a period 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.

[0068] (2) The Remote UE prefers to establish, restore, or reestablish a connection with the network-side device via 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 via an indirect path based on at least factors such as its own mobility speed, remaining battery power, and uplink wireless capability.

[0069] (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.

[0070] In the embodiment of the present application, the remote terminal can communicate with the relay terminal via non-3GPP wireless access technology (eg, Wi-Fi, infrared communication, or Bluetooth communication). In this case, the relay terminal is referred to as a non-3GPP Relay UE.

[0071] 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 (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 determined that the non-direct path establishment condition is met. In this case, the Remote UE regards the serving base station of the Relay UE as its own serving base station.

[0072] (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.

[0073] For example, the Remote UE obtains auxiliary information of a non-3GPP Relay UE, where the auxiliary information includes the Relay UE's Uu connection status and indication information indicating whether the Relay UE is acting as a relay UE. If the Relay UE's Uu connection status in the auxiliary information is available and the indication information indicates that the Relay UE is acting as a relay, it is determined that the indirect path establishment condition is met.

[0074] Among them, the above-mentioned Uu connection state of the 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.

[0075] 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. However, it does not support the interface between the UEs being a non-3GPP interface such as WiFi and Bluetooth. The above-mentioned solution provided in the embodiment of the present application can realize the establishment of a non-direct path based on the non-3GPP relay for the non-3GPP relay scenario.

[0076] In addition, for scenarios 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 serving cell falling below a certain threshold can be used as a trigger condition for establishing an indirect path. However, in some scenarios, such as the aforementioned vehicular communication scenario, determining whether to establish an indirect path solely based on the Uu RSRP of the remote terminal's serving cell may not meet actual needs. For example, if the remote terminal is in a high-speed mobile state, the Uu RSRP of its serving cell may be high. However, since the remote terminal is in a high-speed mobile state, establishing a direct path with the network-side device may cause the remote terminal to frequently switch between cells. For another example, the remote terminal may determine that it prefers to establish an indirect path with the network-side device based on factors such as its own mobile speed, remaining battery power, and uplink wireless capabilities. However, the Uu RSRP of the remote terminal's serving cell may not be below a preset threshold. If the Uu RSRP of the serving cell is still used to determine whether to establish an indirect path, this clearly cannot meet the needs of the remote terminal. Therefore, in the embodiment of the present application, in the cases (1) to (4) above, it is determined that the indirect path establishment condition is met.

[0077] S512: The remote terminal initiates a first target process through the relay terminal.

[0078] In this embodiment of the present application, the first target process includes any one of the following:

[0079] RRC connection establishment process;

[0080] RRC connection recovery process;

[0081] RRC connection reestablishment process.

[0082] For example, if the remote terminal is currently in a disconnected state, the remote terminal may 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. 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 may initiate an RRC connection reestablishment process through the relay terminal, and send an RRC connection reestablishment request message to the Relay UE. The RRC connection reestablishment request message is forwarded to the network-side device through the Relay UE.

[0083] 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 with the help of relay terminals to communicate with the network, it can be applicable to scenarios such as high-speed movement in vehicles.

[0084] 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.

[0085] 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 process of executing the first target process: RRC connection establishment completion message, RRC connection recovery completion message, and RRC connection reconstruction completion message.

[0086] 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 RRC message dedicated to sending the target information.

[0087] In an optional implementation, the method may further include: when it is determined that the indirect path establishment condition is not met, the remote terminal initiating a second target process through the Uu air interface, wherein the second target process includes any one of the following:

[0088] RRC connection establishment process;

[0089] RRC connection recovery process;

[0090] RRC connection reestablishment process.

[0091] 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.

[0092] 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 via 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 connected state via a non-direct connection path, the remote terminal can initiate an RRC connection re-establishment process via the Uu air interface and send an RRC connection re-establishment request message to the network-side device.

[0093] Optionally, in the above implementation, in order to enable the network side device to know the status or tendency of the remote terminal, after the remote terminal initiates the second target process through the Uu air interface, the remote terminal can 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 status of the remote terminal, and the tendency of the remote terminal to only maintain a non-direct connection path.

[0094] In one implementation, the remote terminal can send one of the following messages carrying the target information to the network side device through the Uu air interface during the execution of the second target process: RRC connection establishment completion message, RRC connection recovery completion message, and RRC connection reconstruction completion message.

[0095] 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.

[0096] 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 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 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.

[0097] Optionally, corresponding to the above-mentioned indirect path establishment condition being satisfied, the indirect path establishment condition not being satisfied includes at least one of the following:

[0098] (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;

[0099] For example, if the number of cell reselections by the remote terminal within the duration is less than the second counting threshold and the remote terminal is in a normal mobility state, it is determined that the indirect path establishment condition is not met.

[0100] (2) The remote terminal does not tend to establish, restore, or reestablish a connection with the network-side device via an indirect path;

[0101] For example, the Remote UE may determine that it is not inclined to establish, restore, or reestablish a connection with the 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.

[0102] (3) The remote terminal does not obtain the first indication information sent by the network side device;

[0103] 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 UE and the serving base station through the non-3GPP Relay, it is determined that the indirect path establishment condition is not met.

[0104] (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 an indirect connection path with the network-side device through the relay terminal;

[0105] For example, the SIB sent by the network side device carries first indication information indicating whether a non-direct path is supported or allowed to be established between the non-3GPP Relay UE and the serving base station, and the first indication information indicates that a non-direct path is not supported or allowed to be established between the non-3GPP Relay UE and the serving base station, then it is determined that the non-direct path establishment condition is not met.

[0106] (5) The remote terminal fails to obtain the auxiliary information of the relay terminal;

[0107] 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 indirect path establishment condition is not met.

[0108] (6) The remote terminal obtains auxiliary information of the relay terminal, and the obtained auxiliary information includes at least one of the following: a second indication that the Uu connection status of the relay terminal is unavailable and the relay terminal does not serve as a relay. For example, if the remote terminal obtains auxiliary information of the relay terminal through a connection interface such as Wi-Fi or Bluetooth with the relay terminal, but the obtained auxiliary information contains the second indication that the Uu connection status of the relay terminal is unavailable or the relay terminal does not serve as a relay, then the remote terminal determines that the indirect path establishment condition is not met.

[0109] 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 radio link failure occurs in its serving cell.

[0110] Through the above 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 know the mobility status or tendency of the remote terminal, and then instruct the remote terminal to switch to the non-direct connection path.

[0111] FIG6 is a flow chart showing a method for sending information in accordance with an embodiment of the present invention. 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. As shown in FIG6 , the method can include the following steps.

[0112] 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.

[0113] In an embodiment of the present application, the remote terminal may send the above-mentioned target information to the network-side device via a relay terminal (i.e., a non-direct path) to notify the remote terminal of its mobility status or the tendency to maintain only the non-direct path. Alternatively, the remote terminal may also send the above-mentioned target information to the network-side device via a Uu air interface (i.e., a direct path) to notify the remote terminal of its mobility status or the tendency to maintain only the non-direct path, thereby enabling the network-side device to learn of the remote terminal's mobility status or the tendency to maintain only the non-direct path.

[0114] In one implementation, the remote terminal may, during the execution of the third target process, send an RRC connection establishment completion message, an RRC connection recovery completion message, or an RRC connection re-establishment completion message carrying the target information to the network-side device through a relay terminal or a Uu air interface, 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 re-establishment process. For example, the remote terminal may initiate the third target process through a relay terminal, send an RRC connection establishment request message, an RRC connection recovery request message, or an RRC connection re-establishment request message to the network-side device, and after receiving a response from the network-side device, send an RRC connection establishment completion message, an RRC connection recovery completion message, or an RRC connection re-establishment 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 the response of 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.

[0115] In another implementation, the remote terminal may, after completing the third target process, send a target message carrying the target information to the network side device through the relay terminal or the Uu air interface, and the target message includes one of the following: a relay link terminal information message, a terminal auxiliary information message, or 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.

[0116] In an optional implementation, the remote terminal may send the target information of the remote terminal to the network side device through the relay terminal or the Uu air interface when determining that the indirect path establishment condition is not met.

[0117] Optionally, similar to the above method 500, not meeting the indirect path establishment condition includes at least one of the following:

[0118] (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;

[0119] For example, if the number of cell reselections by the remote terminal within the duration is less than the second counting threshold and the remote terminal is in a normal mobility state, it is determined that the indirect path establishment condition is not met.

[0120] (2) The remote terminal does not tend to establish, restore, or reestablish a connection with the network-side device via an indirect path;

[0121] For example, the Remote UE may determine that it is not inclined to establish, restore, or reestablish a connection with the 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.

[0122] (3) The remote terminal does not obtain the first indication information sent by the network side device;

[0123] 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 UE and the serving base station through the non-3GPP Relay, it is determined that the indirect path establishment condition is not met.

[0124] (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 an indirect connection path with the network-side device through the relay terminal;

[0125] For example, the SIB sent by the network side device carries first indication information indicating whether a non-direct path is supported or allowed to be established between the non-3GPP Relay UE and the serving base station, and the first indication information indicates that a non-direct path is not supported or allowed to be established between the non-3GPP Relay UE and the serving base station, then it is determined that the non-direct path establishment condition is not met.

[0126] (5) The remote terminal fails to obtain the auxiliary information of the relay terminal;

[0127] 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 indirect path establishment condition is not met.

[0128] (6) The remote terminal obtains auxiliary information of the relay terminal, and the obtained auxiliary information includes at least one of the following: a second indication that the Uu connection status of the relay terminal is unavailable and the relay terminal does not serve as a relay. For example, if the remote terminal obtains auxiliary information of the relay terminal through a connection interface such as Wi-Fi or Bluetooth with the relay terminal, but the obtained auxiliary information contains the second indication that the Uu connection status of the relay terminal is unavailable or the relay terminal does not serve as a relay, then the remote terminal determines that the indirect path establishment condition is not met.

[0129] 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 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.

[0130] Optionally, 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 remote terminal sends the target information of the remote terminal to the network side device through the relay terminal or the 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 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 the relay terminal, for example, communicate with the network side device through a non-3GPP Relay UE.

[0131] 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 know the mobility status or tendency of the remote terminal, and then determine whether to establish a direct connection path or an indirect connection 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.

[0132] FIG7 is a flow chart illustrating a method for acquiring information according to an embodiment of the present application. This 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. As shown in FIG7 , the method may include the following steps.

[0133] S710, 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, 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.

[0134] 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.

[0135] In an optional implementation, after receiving the target information of the remote terminal, if the remote terminal currently sends the target information through a relay terminal, the network device may instruct the remote terminal to maintain a non-direct path. If the remote terminal currently sends the target information through a Uu air interface, the network device may instruct the remote terminal to switch. Therefore, after the network device receives the target information of the remote terminal sent by the remote terminal through a relay terminal or a Uu air interface, the method may further include: the network device sending 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 device through a non-direct path. With this implementation, under the premise that a direct path already 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. Under the premise that a non-direct path already 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.

[0136] In an optional implementation, before S710, the method may further include: the network-side device sending detection parameters, where the detection parameters include: the duration, a first counting threshold, and a second counting threshold, where the first counting threshold is greater than the second counting threshold. The remote terminal may determine the mobility status of the remote terminal based on the detection parameters. For details, refer to the relevant description of method 500 above and are not repeated here.

[0137] The following describes the technical solution provided in the embodiment of the present application using a non-3GPP relay scenario through specific implementation methods.

[0138] FIG8 shows another flow chart of a method for processing a network connection according to an embodiment of the present application. As shown in FIG8 , the method may include the following steps:

[0139] 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.

[0140] This step is optional.

[0141] Step 802: The Remote UE determines whether an indirect path establishment condition is met.

[0142] 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. Therefore, 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. The Remote UE determines whether the indirect path establishment conditions are met.

[0143] Specifically, the Remote UE may determine whether the following conditions are met:

[0144] 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.

[0145] The remote UE can detect its current mobility state in the following ways:

[0146] The serving base station broadcasts a set of detection parameters to the Remote UE, which includes: T CRmax ,N CR_H ,N CR_M .

[0147] If the Remote UE determines that the CRmax The number of cell reselections that occur 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.

[0148] 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.

[0149] If the Remote UE determines that the CRmax The number of cell reselections within a period 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.

[0150] Condition 2: Whether the Remote UE prefers to establish or restore an RRC connection via an indirect path. If the Remote UE prefers to establish or restore an RRC connection via an indirect path, Condition 2 is determined to be met.

[0151] The tendency of the Remote UE may be a result of at least considering various factors such as its own moving speed, remaining power, uplink wireless capability, etc. The specific algorithm is not limited in the embodiment of this application.

[0152] Condition 3: The Remote UE obtains an SIB message from the serving base station, and the SIB message carries first indication information regarding whether establishment of an indirect path between the Remote UE and the serving base station via a non-3GPP Relay UE is supported or permitted. Condition 3 is determined to be satisfied when the first indication information indicates that establishment of an indirect path between the Remote UE and the serving base station via a non-3GPP Relay UE is supported or permitted.

[0153] Condition 4: The Remote UE obtains auxiliary information of a non-3GPP Relay UE, the auxiliary information including the Uu connection status of the Relay UE or the second indication information indicating 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 that it is acting as a relay UE, Condition 4 is determined to be met.

[0154] Step 803: On 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.

[0155] Step 804: The remote terminal receives the RRC connection establishment message or the RRC connection recovery message sent by the base station. The RRC connection establishment message or the RRC connection recovery message is forwarded to the Remote UE via the non-3GPP Relay UE.

[0156] 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.

[0157] The RRC connection establishment complete message or the RRC connection recovery complete 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 an indirect connection path.

[0158] Alternatively, the RRC connection establishment complete message or the RRC connection recovery complete message in step 805 may not carry the above-mentioned remote UE related information, and the method may further include step 806.

[0159] 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. The SidelinkUEInformation message or the UEAssitanceInformation message or the new RRC message is forwarded to the base station via the non-3GPP Relay UE. The SidelinkUEInformation message or the UEAssitanceInformation message or the new RRC message carries remote UE related information. 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 connection path.

[0160] FIG9 shows another flow chart of a method for processing a network connection according to an embodiment of the present application. As shown in FIG9 , the method may include the following steps:

[0161] Step 901 is the same as step 801.

[0162] Step 902: The Remote UE determines whether an indirect path establishment condition is met.

[0163] Specifically, the Remote UE may determine whether the following conditions are met:

[0164] Condition 1: Whether the current mobility state of the Remote UE meets the preset state. If 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.

[0165] 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 a direct path or not via an indirect path, it is determined that Condition 2 is not met.

[0166] The Remote UE tendency may be a result of at least considering various factors such as its own moving speed, remaining power, uplink wireless capability, etc. The specific algorithm is not limited in the embodiment of this application.

[0167] Condition 3: The Remote UE obtains an SIB message from the serving base station in step 901. If the SIB message does not carry the first indication information indicating whether establishment of a non-direct connection path between the serving base station and the remote UE through a non-3GPP Relay UE is supported or permitted, or if the SIB message carries the first indication information and the first indication information indicates that establishment of a non-direct connection path between the serving base station and the remote UE through a non-3GPP Relay UE is not supported or prohibited, then it is determined that Condition 3 is not met.

[0168] Condition 4: The Remote UE obtains the auxiliary information of the non-3GPP Relay UE in step 801. 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.

[0169] 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.

[0170] 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.

[0171] Step 905: The remote terminal directly sends an RRC connection establishment complete message or an RRC connection recovery complete message to the base station via the Uu air interface.

[0172] The RRC connection establishment complete message or the RRC connection recovery complete 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 an indirect connection path.

[0173] 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, step 907 is executed.

[0174] Step 906: Send a SidelinkUEInformation message or a UEAssitanceInformation message or a new RRC message directly through the Uu air interface, where the SidelinkUEInformation message or the UEAssitanceInformation message or the new RRC message carries information related to the remote UE. The information related to the remote UE includes at least one of the following: the current mobility status of the remote UE; and the tendency of the remote UE to maintain only an indirect connection path.

[0175] Step 907: The remote terminal directly receives the RRC reconfiguration message sent by the base station through the Uu air interface. The RRC reconfiguration message carries path switching configuration information instructing the remote UE to switch to an indirect path based on a non-3GPP relay.

[0176] 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 complete message to the non-3GPP Relay UE. The RRC reconfiguration complete message is forwarded to the base station via the non-3GPP Relay UE.

[0177] FIG10 shows another flow chart of a method for processing a network connection according to an embodiment of the present application. As shown in FIG10 , the method may include the following steps:

[0178] 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.

[0179] 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.

[0180] Step 1003: The remote terminal directly sends an RRC connection establishment complete message or an RRC connection recovery complete message to the base station via the Uu air interface.

[0181] The RRC connection establishment complete message or the RRC connection recovery complete 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 an indirect connection path.

[0182] 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, step 1005 is directly executed.

[0183] Step 1004: The remote terminal directly sends a SidelinkUEInformation message or a UEAssitanceInformation message or a new RRC message through the Uu air interface. The SidelinkUEInformation message or the UEAssitanceInformation message or the new RRC message carries remote UE related information. 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 connection path.

[0184] Step 1006: The remote terminal directly receives an RRC reconfiguration message sent by the base station through the Uu air interface. The RRC reconfiguration message carries path switching configuration information instructing the remote UE to switch to an indirect path based on a non-3GPP relay.

[0185] 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 complete message to the non-3GPP Relay UE. The RRC reconfiguration complete message is forwarded to the base station via the non-3GPP Relay UE.

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.
