[0021] The following clearly and completely describes the technical concepts in the embodiments of this application, linking them to the drawings of the embodiments. Clearly, the embodiments described are only some, and not all, embodiments of this application. All other embodiments derived from the embodiments of this application without the creative effort of a person skilled in the art are all within the scope of protection of this application.

[0022] The terms "first," "second," etc., used in the specification and claims of this application are intended to distinguish similar subjects and not to describe a specific order or sequence. It should be understood that the data used in this manner are interchangeable where appropriate, so that the embodiments of this application can be carried out in an order other than those illustrated or described herein, and the subjects distinguished by "first," "second," etc., are generally of the same kind and do not limit the number of subjects; for example, the first subject may be one or more. Furthermore, "and / or" in the specification and claims refers to at least one of the related subjects, and the letter " / " generally indicates that the related subjects are in an "or" relationship.

[0023] It should be noted that the technologies described in the embodiments of this application are not limited to Long Term Evolution (LTE) / LTE-Advanced (LTE-A) systems, but are also applicable to other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA), and other systems. The terms "system" and "network" in the embodiments of this application are always used interchangeably, and the technologies described may be applied to the systems and radio technologies mentioned above, or to other systems and radio technologies. However, the following description uses the New Radio (NR) system for illustrative purposes, and uses NR terminology in most of the following descriptions, but these technologies have applications other than NR system applications, for example, sixth generation (6 th It may be applied to 6G (Generation 1) communication systems.

[0024] In the embodiments of this application, the terminal may also be called terminal equipment or user equipment (UE), and the terminal may be terminal-side equipment such as a mobile phone, tablet personal computer, laptop computer (or notebook computer), personal digital assistant (PDA), palmtop computer, netbook, ultra-mobile personal computer (UMPC), mobile internet device (MID), wearable device, or in-vehicle equipment (VUE), or pedestrian terminal (PUE), and wearable devices include bracelets, earphones, glasses, etc. It should be noted that the embodiments of this application do not limit the specific type of terminal.

The base station is not limited to any particular technical term, and for the purposes of this explanation, only a base station in an NR system is given as an example in the embodiments of this application, but this does not limit the specific type of base station.

[0025] To better understand the proposed solution in this application, the following points will be described first.

[0026] In LTE systems, multimedia multicast traffic (Multimedia Broadcast Multicast Service, MBMS) can be transmitted using two methods: MBMS single-frequency network and cell multicast (single cell-point to multi-point, SC-PTM).

[0027] MBSFN method: This method involves multiple cells within the same MBSFN area simultaneously transmitting the same multicast traffic. From the UE's perspective, this is equivalent to receiving the same data via multiple paths. Transmission occurs via a Physical Multicast Channel (PMCH) within MBSFN subframes. Both MBMS traffic control information (control channel parameters, traffic channel parameters, scheduling information, etc.) and data information are transmitted using multicast. This allows both idle and connected UEs to receive MBMS traffic, and MBMS data information is transmitted only within MBSFN subframes. Here, control information related to multicast traffic is transmitted via system information (e.g., SIB13) and the Multicast Control Channel (MCCH), while data is transmitted via the Multicast Traffic Channel (MTCH).

[0028] SC-PTM: Transmission is via a Physical Downlink Shared Channel (PDSCH) scheduled on a Physical Downlink Control Channel (PDCCH). Here, control information is transmitted via system information (e.g., SIB20) and a Single Cell Multicast Control Channel (SC-MCCH), and data is transmitted via a Single Cell Multicast Traffic Channel (SC-MTCH). Here, SC-MCCH is transmitted via a PDSCH scheduled on a Single Cell Radio Network Temporary Identifier (SC-RNTI) PDCCH, and SC-MTCH is transmitted via a PDSCH scheduled on a Group-Radio Network Temporary Identifier (G-RNTI) PDCCH.

[0029] In the following sections, we will explain in detail how to establish connections according to the embodiments of this application, using specific examples and their application scenarios, while linking them to the drawings.

[0030] Referring to Figure 1a, an embodiment of this application provides a method for establishing a connection used in a first terminal, and this method is The procedure includes step 101 of transmitting first information to a wireless access network device if no valid AS security parameters are available, which is used to obtain connection status operation instructions via the wireless access network device.

[0031] In the embodiments of this application, the absence of effective AS security parameters may refer to a scenario in which the first terminal requests the establishment of a Radio Resource Control (RRC) connection with a wireless access network device, the wireless access network device agrees to establish the RRC connection, the first terminal moves from an idle state to a connected state, but access layer AS security is not activated.

[0032] As an example, the terminal may carry the first information via the RRCSetupComplete message and transmit the first information to the wireless access network equipment.

[0033] In the embodiments of this application, after a terminal establishes a connection with a wireless access network device, the terminal transmits first information to the wireless access network device and obtains instructions for connection status operations via the wireless access network device. Thus, when a terminal establishes a connection only with a wireless access network device, it can obtain instructions for connection status operations via the wireless access network device and perform operations related to the connection status based on the instructions. This enables the terminal to establish a connection only with a wireless access network device without constantly establishing a connection with a core network device.

[0034] In some embodiments, the first information is NAS information, and in such a method, it is possible to avoid connecting to core network-side devices via a signaling process.

[0035] In some embodiments, the core network management state of the first terminal is idle, and in such a configuration, it is possible to achieve not connecting to the core network equipment via the local.

[0036] In some embodiments, the first information is generated based on the Non-Access Stratum (NAS) security parameters of the first terminal, and the wireless access network equipment transmits this first information to the core network equipment, which can then check the first terminal based on the first information.

[0037] Furthermore, in some embodiments, after transmitting first information to a wireless access network device, the method further includes receiving second information transmitted by the wireless access network device and performing an operation related to the connection status based on the second information.

[0038] In the embodiments of this application, performing operations related to the connection state based on second information is: (1) Entering a wireless disconnection state or disconnecting the wireless connection, for example, the wireless disconnection state may be an idle state. (2) Maintaining a wireless connection state, converting to a wireless connection state, or maintaining a wireless connection, (3) including at least one of converting to a core network connection state or performing a core network connection establishment process.

[0039] Selectively, in some embodiments, the first terminal performs a default operation if the second information is not received within the time agreed upon by the protocol or arranged by the network.

[0040] For example, the first terminal starts a first timer when it begins transmitting the first information to the wireless access network equipment, when it ends transmitting the first information to the wireless access network equipment, or after it has transmitted the first information to the wireless access network equipment, and the duration of the first timer may be determined by the protocol or set by the network.

[0041] If the second piece of information is received while the first timer is running, the first timer is stopped.

[0042] If the first timer times out, the default operation is performed.

[0043] In the embodiments of this application, the default operation is: Entering a wireless disconnection state or disconnecting the wireless connection, Maintaining a wireless connection state, converting to a wireless connection state, or maintaining a wireless connection, This includes one of the following: converting to a core network connection state, or performing a core network connection establishment process.

[0044] Selectively referring to Figure 1b, the figure shows a relay scenario in which the first terminal is a relay terminal for the second terminal, i.e., the first terminal is a relay UE (e.g., a Layer 2 relay terminal), and the second terminal is a remote UE.

[0045] For this scenario, this method is: (1) Receiving the fourth piece of information transmitted by the second terminal, (2) Further includes transmitting the first information to the wireless access network equipment.

[0046] In the embodiments of this application, the first information is the fourth information, or the first information is generated based on the NAS security parameters of the first terminal and the fourth information, and optionally, the fourth information is generated based on the NAS security parameters of the second terminal.

[0047] Furthermore, after transmitting the first information to the wireless access network equipment, this method (3) Receiving second information transmitted by wireless access network equipment, (4) Further including transmitting a sixth piece of information to the second terminal to instruct it to perform an operation related to the connection status based on the second piece of information, In the embodiments of this application, the first terminal receives fourth information from the second terminal and selectively transmits this fourth information as first information to the wireless access network equipment, or generates first information based on the NAS security parameters of the first terminal and the fourth information and transmits it to the wireless access network equipment, and then transmits sixth information to the second terminal to instruct it to perform an operation related to the connection status based on the second information returned from the wireless access network equipment. In this way, even in relay scenarios, the terminal (e.g., remote terminal) can establish a connection only with the wireless access network equipment.

[0048] Referring to Figure 2, an embodiment of this application provides a method for establishing a connection used in a second terminal, and this method is, Step 201 includes sending a fourth piece of information to a first terminal if no valid AS security parameters are present, which is used to obtain instructions for connection status operations via the first terminal.

[0049] In the embodiment of this application, for the scenario shown in Figure 1b, the first terminal is a relay terminal for the second terminal, i.e., the first terminal is a relay UE and the second terminal is a remote UE.

[0050] If the above-mentioned valid AS security parameters are not present, this may refer to a scenario in which the second terminal requests the establishment of an RRC connection with the wireless access network equipment via the first terminal, the wireless access network equipment agrees to establish the RRC connection, the second terminal moves from an idle state to a connected state, but AS security is not activated.

[0051] As an example, the first terminal may carry the fourth information via the RRCSetupComplete message and transmit the fourth information from the second terminal to the wireless access network equipment.

[0052] In some embodiments, the core network management state of the second terminal is idle, and such a method can be achieved by not connecting to the core network-side equipment via the local.

[0053] In some embodiments, the fourth information is generated based on the NAS security parameters of the second terminal, and the second terminal thus transmits the fourth information to the wireless access network equipment via the first terminal (as can be understood, in conjunction with the description of the first terminal-side method above, it can be determined that the first terminal transmits this fourth information to the wireless access network equipment as first information, or that it may generate first information based on the NAS security parameters of the first terminal and the fourth information and transmit it to the wireless access network equipment), and the wireless access network equipment transmits this fourth information to the core network equipment (for example, the wireless access network equipment transmits the fourth information to the core network equipment of the second terminal), and the core network equipment can check the second terminal based on the fourth information.

[0054] Furthermore, the first information may be generated based on the NAS security parameters of the first terminal and the fourth information. In such a case, after the wireless access network device receives the first information, for example, the wireless access device may transmit the fourth information included in the first information to the core network device of the second terminal, and the core network device of the second terminal may verify the second terminal based on the fourth information. Alternatively, the wireless access device may transmit information other than the fourth information included in the first information to the core network device of the first terminal, and the core network device of the first terminal may verify the first terminal based on the received information. Furthermore, the core network device of the second terminal and the core network device of the first terminal may be the same core network device or different core network devices.

[0055] Furthermore, after transmitting the fourth information to the first terminal, the method further includes receiving the sixth information transmitted by the first terminal and performing an operation related to the connection status based on the sixth information.

[0056] In the embodiments of this application, performing operations related to the connection state is, (1) Entering a state of wireless disconnection between devices, or disconnecting the wireless connection between devices, for example, the wireless disconnection state may be an idle state. (2) Maintaining the wireless connection state between devices, converting to a wireless connection state between devices, or maintaining the wireless connection between devices, (3) including at least one of converting to a core network connection state or performing a core network connection establishment process.

[0057] Selectively, in some embodiments, the second terminal performs a default operation if the sixth information is not received within the time agreed upon by the protocol or arranged by the network.

[0058] In the embodiments of this application, the default operation is: Entering a state of wireless disconnection between devices, or disconnecting the wireless connection between devices, Maintaining the wireless connection state between devices, converting to a wireless connection state between devices, or maintaining the wireless connection between devices, This involves either converting to a core network connection state or executing the core network connection establishment process.

[0059] For example, the connection between the devices mentioned above may refer to the PC5 connection. For instance, disconnecting the wireless connection between devices may be understood as disconnecting the PC5 connection between the devices, and maintaining the wireless connection between devices may be understood as maintaining the PC5 connection between the devices.

[0060] Referring to Figure 3, the embodiment of this application provides a method for establishing a connection used in wireless access network equipment, and this method is Step 301: Receiving first information from a first terminal, and transmitting or refusing to transmit the first information to a core network-side device, wherein the first information is used by the core network-side device to transmit or refuse to transmit a third information to a radio access network-side device based on the first information. The steps include receiving first information from a first terminal and transmitting or refusing to transmit the first information to a core network-side device, wherein the first information is used by the core network-side device to transmit or refuse to transmit fifth information to a radio access network-side device based on the first information.

[0061] It should be explained that, as can be seen by linking the descriptions of the first terminal-side method flow and the second terminal-side method flow above, the method of the embodiment of this application may also be applied to establishing a connection in a relay scenario. Step 301 above is applied to the execution flow of the wireless access network-side equipment in a non-relay scenario, and Step 302 above is applied to the execution flow of the wireless access network-side equipment in a relay scenario.

[0062] In the embodiments of this application, the wireless access network device may choose to transmit the first information to the core network device after receiving the first information from the first terminal, or it may refuse to transmit the first information, i.e., it may not transmit the first information to the core network device.

[0063] In some embodiments, the first information is NAS information, for example, AS layer information, and such a method can ensure that the first terminal does not connect to the core network equipment via a signaling process.

[0064] Furthermore, in some embodiments, this method is The system further includes receiving a third piece of information transmitted by a core network device, and / or receiving a fifth piece of information transmitted by a core network device, and transmitting a second piece of information to the terminal to instruct it to perform a connection status operation based on the third piece of information and / or the fifth piece of information.

[0065] In the embodiments of this application, the core network-side equipment includes the core network-side equipment of a first terminal and the core network-side equipment of a second terminal, both of which may be the same or different, and in the actual implementation process, the radio access network-side equipment may receive only the third piece of information from the core network-side equipment, or only the fifth piece of information from the core network-side equipment, or it may receive both the third piece of information and the fifth piece of information from the core network-side equipment. Based on the third piece of information and / or the fifth piece of information, the radio access network-side equipment transmits a second piece of information to the first terminal to instruct it to perform a connection status operation.

[0066] in particular, If a wireless access network device receives third information from a core network device, and this third information instructs the first terminal to enter a wireless disconnection state or to disconnect the wireless connection, the wireless access network device determines second information based on the third information and transmits this second information to the first terminal, and this second information instructs the first terminal to enter a wireless disconnection state or to disconnect the wireless connection. If a wireless access network device receives third information from a core network device, and this third information instructs the first terminal to maintain a wireless connection, convert to a wireless connection, or maintain a wireless connection, the wireless access network device determines second information based on the third information and transmits this second information to the first terminal, and this second information instructs the first terminal to maintain a wireless connection, convert to a wireless connection, or maintain a wireless connection. If a wireless access network device receives third information from a core network device, and this third information instructs the first terminal to convert to a core network connection state or to perform the core network connection establishment process, the wireless access network device determines second information based on the third information and transmits this second information to the first terminal, and this second information instructs the first terminal to convert to a core network connection state or to perform the core network connection establishment process. The process by which wireless access network equipment transmits the second information to the terminal based on the fifth information is the same as the process described above for transmitting the second information to the terminal based on the third information, and will not be explained further.

[0067] It should be explained that when a wireless access network device receives the third and fifth pieces of information, it must transmit the second piece of information based on the third and fifth pieces of information. For example, if the third piece of information instructs the first terminal to maintain or convert to a wireless connection state, and the fifth piece of information instructs the first terminal to enter a wireless disconnection state or to disconnect the wireless connection, the wireless access network device transmits the second piece of information, which instructs the first terminal to enter a wireless disconnection state or to disconnect the wireless connection. As another example, if the third piece of information instructs the first terminal to maintain or convert to a wireless connection state, and the fifth piece of information instructs the first terminal to maintain or convert to a wireless connection state, the wireless access network device transmits the second piece of information, which instructs the first terminal to maintain or convert to a wireless connection state or to maintain the wireless connection.

[0068] Selectively, in some embodiments, the wireless access network-side equipment performs a default operation if the third and / or fifth pieces of information have not been received within the time stipulated by the protocol or arranged by the network.

[0069] For example, a wireless access network device may start a second timer when it begins transmitting the first information to the core network device, when it ends transmitting the first information to the core network device, or after it has transmitted the first information to the core network device, and the duration of the second timer may be determined by the protocol or set by the network side.

[0070] If the third piece of information and / or the fifth piece of information is received while the second timer is running, the second timer is stopped.

[0071] If the second timer times out, the default operation is performed.

[0072] As another example, a wireless access network device may start a third timer when it begins transmitting the first information to the core network device, when it ends transmitting the first information to the core network device, or after it has transmitted the first information to the core network device, and the duration of the third timer may be determined by the protocol or set by the network side.

[0073] If the third timer is running and the third piece of information and / or the fifth piece of information is received, the third timer is stopped.

[0074] If the third timer has not timed out, the wireless access network device transmits the second information based on the received third and / or fifth information. If the third timer has timed out and the wireless access network device has not received the third and fifth information, it performs the default operation.

[0075] In some embodiments, this default operation is to either send or refuse to send second information to the terminal to instruct it on the connection status operation.

[0076] Selectively, in some embodiments, the method further includes receiving first information from a first terminal and, after either transmitting or refusing to transmit the first information to a core network-side device, transmitting second information to the first terminal for instructing a connection status operation.

[0077] In the embodiments of this application, the wireless access network device may, after transmitting the first information to the core network device, directly transmit the second information to the first terminal for instructing it to perform a connection status operation; that is, the wireless access network device does not need to receive the third and / or fifth information from the core network device.

[0078] In another example, the wireless access network device may refuse to transmit the first information to the core network device. In such a case, the wireless access network device may transmit the second information to the terminal device, or it may not transmit the second information to the terminal. If the wireless access network device transmits the second information to the terminal device, for example, if the terminal device does not support establishing only a wireless connection (e.g., an air interface wireless connection or an RRC connection), the wireless access network device may transmit the second information to instruct a disconnection operation, or the second information to instruct a core network connection operation (e.g., instructing the first terminal to perform a core network connection operation). In another example, if the terminal device supports establishing only a wireless connection (e.g., an air interface wireless connection or an RRC connection), the wireless access network device may transmit the second information to instruct a connection operation.

[0079] Furthermore, the second piece of information mentioned above specifically states: (1) Instructing a deactivation operation, for example, if the second piece of information instructs a deactivation operation, the terminal device enters or converts to a wireless disconnection state, or disconnects the wireless connection. (2) Instructing a connection operation, for example, if the second piece of information instructs a connection operation, the terminal device shall maintain the wireless connection state, convert to a wireless connection state, or maintain the wireless connection. (3) Instructing the first terminal to perform a core network connection operation, for example, if the second information instructs the first terminal to perform a core network connection operation, the terminal equipment converts to a core network connection state or performs a core network connection establishment process.
