For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally represents that the objects associated with each other are in an "or" relationship.

[0052] It is worth noting that the technology described in the embodiments of the present application is not limited to the Long Term Evolution (LTE) / LTE-Advanced (LTE-A) system, but can also be used in 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 the present application are often used interchangeably, and the described technology can be used for the systems and radio technologies mentioned above as well as for other systems and radio technologies. However, the following description describes a New Radio (NR) system for illustrative purposes, and the NR terminology is used in most of the following descriptions, although these technologies can also be applied to applications other than NR system applications, such as the 6th generation (6 th Generation, 6G) communication system.

[0053] In the embodiments of the present application, the terminal may also be referred to as a terminal device or a user terminal (User Equipment, UE), and the terminal may 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 type of the terminal is not limited in the embodiments of the present application.

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.

[0054] In order to better understand the solution provided by this application, the following contents are first described:

[0055] In the LTE system, the Multimedia Broadcast Multicast Service (MBMS) can be sent in two ways: MBMS Single Frequency Network (Multimedia Broadcast multicast service Single Frequency Network) and single cell-point to multi-point (SC-PTM).

[0056] MBSFN mode: Multiple cells in the same MBSFN area send the same multicast service at the same time. From the UE side, it is equivalent to receiving the same data through multiple paths. It is sent through the Physical Multicast Channel (PMCH) in the MBSFN subframe. The control information (control channel parameters and service channel parameters, scheduling information, etc.) and data information of the MBMS service are sent in a broadcast manner, so that both idle UEs and connected UEs can receive MBMS services, and the MBMS data information is only sent in MBSFN subframes. Among them, the control information related to the multicast service is sent through the system information (such as SIB13) and the broadcast control channel (Multicast Control Channel,) MCCH, and the data is sent through the broadcast traffic channel (Multicast Traffic Channel, MTCH).

[0057] SC-PTM: Sent through the Physical Downlink Shared Channel (PDSCH) scheduled by the Physical Downlink Control Channel (PDCCH). Control information is sent through system information (such as SIB20) and the Single Cell Multicast Control Channel (SC-MCCH), and data is sent through the Single Cell Multicast Traffic Channel (SC-MTCH). SC-MCCH is sent through the PDSCH scheduled by the Single Cell Radio Network Temporary Identity (SC-RNTI) PDCCH, and SC-MTCH is sent through the PDSCH scheduled by the Group Radio Network Temporary Identity (G-RNTI) PDCCH.

[0058] The following describes in detail the method for establishing a connection provided by the embodiment of the present application through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0059] See also Figure 1a , an embodiment of the present application provides a method for establishing a connection, applied to a first terminal, the method comprising:

[0060] Step 101: In the absence of valid AS security parameters, first information is sent to a wireless access network side device, where the first information is used to obtain an indication of a connection state operation through the wireless access network side device.

[0061] In an embodiment of the present application, the situation where there are no valid AS security parameters may refer to: the first terminal requests to establish a radio resource control (Radio Resource Control, RRC) connection with the wireless access network side device, and the wireless access network side device agrees to establish the RRC connection, and the first terminal enters the connected state from the idle state but the access layer AS security has not yet been activated.

[0062] As an example, the terminal may carry the first information through an RRCSetupComplete message and send the first information to the radio access network device.

[0063] In an embodiment of the present application, after the terminal establishes a connection with the wireless access network side device, the terminal sends first information to the wireless access network side device, and obtains an indication of a connection state operation through the wireless access network side device. In this way, when the terminal only establishes a connection with the wireless access network side device, the terminal can obtain an indication of a connection state operation through the wireless access network side device, and perform connection state-related operations based on the indication, thereby enabling the terminal to only establish a connection with the wireless access network side device without always establishing a connection with the core network side device.

[0064] In some implementations, the first information is non-NAS information, which can be achieved through a signaling process without connecting to a core network side device.

[0065] In some implementations, the core network management state of the first terminal is an idle state, which can be achieved locally without connecting to the core network side device.

[0066] In some embodiments, the first information is generated based on the non-access stratum (NAS) security parameters of the above-mentioned first terminal, so that the first information can be sent by the wireless access network side device to the core network side device, and the core network side device verifies the first terminal based on the first information.

[0067] Furthermore, in some implementations, after sending the first information to the wireless access network side device, the method further includes: receiving second information sent by the wireless access network side device; and performing connection status related operations according to the second information.

[0068] In the embodiment of the present application, performing connection state related operations according to the second information includes at least one of the following:

[0069] (1) Entering a wireless non-connection state, or releasing a wireless connection; as an example, the wireless non-connection state may be an idle state.

[0070] (2) Maintain or switch to a wireless connection state, or maintain a wireless connection;

[0071] (3) Convert to core network connection state, or execute core network connection establishment process.

[0072] Optionally, in some implementations, if the first terminal does not receive the second information within a time specified by the protocol or configured by the network, a default operation is performed.

[0073] As an example, the first terminal starts a first timer when it starts sending the first information to the wireless access network device or when it finishes sending the first information to the wireless access network device or after sending the first information to the wireless access network device. The duration of the first timer may be agreed upon by the protocol or configured on the network side.

[0074] If second information is received while the first timer is running, the first timer is stopped.

[0075] If the first timer times out, a default operation is performed.

[0076] In the embodiment of the present application, the default operation includes one of the following:

[0077] Enter wireless non-connection state, or release wireless connection;

[0078] Maintain or switch to wireless connection state, or maintain wireless connection;

[0079] Convert to core network connection state, or execute core network connection establishment process.

[0080] Alternatively, see Figure 1b , the figure shows a relay scenario, in which the first terminal is a relay terminal of the second terminal, that is, the first terminal is a relay UE (for example, a layer 2 relay terminal, layer 2 relay UE), and the second terminal is a remote UE.

[0081] For this scenario, the method further includes:

[0082] (1) receiving fourth information sent by the second terminal;

[0083] (2) Sending first information to the wireless access network side device.

[0084] In an embodiment of the present application, the first information is the fourth information, or the first information is generated based on the NAS security parameter of the first terminal and the fourth information. Optionally, the fourth information is generated based on the NAS security parameter of the second terminal.

[0085] Further, after sending the first information to the wireless access network side device, the method further includes:

[0086] (3) receiving second information sent by the wireless access network side device;

[0087] (4) sending sixth information to the second terminal according to the second information, where the sixth information is used to instruct the second terminal to perform a connection state-related operation;

[0088] In the embodiment of the present application, the first terminal receives the fourth information from the second terminal, and optionally sends the fourth information as the first information to the wireless access network side device, or generates the first information based on the NAS security parameter of the first terminal and the fourth information and sends it to the wireless access network side device, and then sends the sixth information for instructing the second terminal to perform connection state related operations to the second terminal according to the second information returned by the wireless access network side device. In this way, for the relay scenario, it is also possible to achieve that the terminal (such as a remote terminal) only establishes a connection with the wireless access network side device.

[0089] See also Figure 2 , an embodiment of the present application provides a method for establishing a connection, which is applied to a second terminal, and the method includes:

[0090] Step 201: In the absence of valid AS security parameters, fourth information is sent to a first terminal, where the fourth information is used to obtain an indication of a connection state operation through the first terminal.

[0091] In the embodiments of the present application, Figure 1b In the scenario shown, the first terminal is a relay terminal of the second terminal, that is, the first terminal is a relay UE and the second terminal is a remote UE.

[0092] The above-mentioned situation without valid AS security parameters may refer to: the second terminal requests to establish an RRC connection with the wireless access network side device through the first terminal, and the wireless access network side device agrees to establish the RRC connection, and the second terminal enters the connected state from the idle state, but the AS security scenario is not activated.

[0093] As an example, the first terminal may carry the fourth information through an RRCSetupComplete message and send the fourth information from the second terminal to the radio access network device.

[0094] In some implementations, the core network management state of the second terminal is an idle state, and this method can be implemented locally without connecting to the core network side device.

[0095] In some embodiments, the fourth information is generated based on the NAS security parameters of the above-mentioned second terminal, so that the second terminal can send the fourth information to the wireless access network side device through the first terminal (it can be understood that, in combination with the description of the aforementioned first terminal side method, it can be determined that the first terminal can send the fourth information as the first information to the wireless access network side device or generate the first information based on the NAS security parameters of the first terminal and the fourth information and send it to the wireless access network side device), and then the wireless access network side device sends the fourth information to the core network side device (for example, the wireless access network device sends the fourth information to the core network device of the second terminal), and the core network side device verifies the second terminal based on the fourth information.

[0096] It is further explained that the first information can be generated based on the NAS security parameters of the first terminal and the fourth information. In this case, when the wireless access network device receives the first information, as an example, the wireless access device can send 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 verifies the second terminal based on the fourth information; the wireless access device can send the information in the first information except the fourth information to the core network device of the first terminal, and the core network device of the first terminal verifies the first terminal based on the received information. It should be noted that the core network device of the second terminal and the core network device of the first terminal can be the same core network device or different core network devices.

[0097] Furthermore, after sending the fourth information to the first terminal, the method further includes: receiving sixth information sent by the first terminal; and performing connection status related operations according to the sixth information.

[0098] In the embodiment of the present application, performing connection state related operations includes at least one of the following:

[0099] (1) Entering a wireless non-connected state between devices, or releasing a wireless connection between devices; as an example, the wireless non-connected state may be an idle state.

[0100] (2) Maintain or convert to a wireless connection state between devices, or maintain a wireless connection between devices;

[0101] (3) Transition to core network connection state, or execute core network connection establishment process

[0102] Optionally, in some implementations, if the second terminal does not receive the sixth information within a time specified by the protocol or configured by the network, a default operation is performed.

[0103] In the embodiment of the present application, the default operation is any one of the following:

[0104] Enter the wireless non-connected state between devices, or release the wireless connection between devices;

[0105] Maintain or switch to a wireless connection state between devices, or maintain a wireless connection between devices;

[0106] Convert to core network connection state, or execute core network connection establishment process.

[0107] As an example, the inter-device connection may refer to a PC5 connection. For example, releasing the inter-device wireless connection may be understood as releasing the inter-device PC5 connection; maintaining the inter-device wireless connection may be understood as maintaining the inter-device PC5 connection.

[0108] See also Figure 3 The embodiment of the present application provides a method for establishing a connection, which is applied to a wireless access network side device, and the method includes at least one of the following:

[0109] Step 301: receiving first information from a first terminal, and sending or refusing to send the first information to a core network side device, where the first information is used by the core network side device to send or refuse to send third information to a wireless access network side device based on the first information;

[0110] Step 302: Receive first information from the first terminal, and send or refuse to send the first information to the core network side device, where the first information is used by the core network side device to send fifth information to the wireless access network side device or refuse to send the fifth information based on the first information.

[0111] It should be noted that, in combination with the description of the first terminal side method flow and the second terminal side method flow, it can be seen that the method of the embodiment of the present application can also be used to establish a connection in a relay scenario. The above step 301 is for the execution process of the wireless access network side device in a non-relay scenario, and the above step 302 is for the execution process of the wireless access network side device in a relay scenario.

[0112] In an embodiment of the present application, after receiving the first information from the first terminal, the wireless access network side device can choose to send the first information to the core network side device, or can refuse to send the first information, that is, not send the first information to the core network side device.

[0113] In some implementations, the first information is non-NAS information, for example, the first information is AS layer information. This method can achieve that the first terminal is not connected to the core network side device through a signaling process.

[0114] Furthermore, in some embodiments, the method further comprises:

[0115] Receive the third information sent by the core network side device, and / or receive the fifth information sent by the core network side device, and send the second information to the terminal based on the third information and / or the fifth information, where the second information is used to indicate the connection status operation.

[0116] In the embodiment of the present application, the core network side device includes a core network side device of the first terminal and a core network side device of the second terminal, and the core network side devices of the two may be the same or different. In the actual implementation process, the wireless access network side device may only receive the third information from the core network side device, or may only receive the fifth information from the core network side device, or may receive the third information and the fifth information from the core network side device. The wireless access network side device sends the second information for indicating the connection state operation to the first terminal according to the third information and / or the fifth information.

[0117] Specifically:

[0118] If the wireless access network side device receives third information from the core network side device, and the third information indicates that the first terminal enters a wireless non-connected state or releases a wireless connection, the wireless access network side device determines second information according to the third information, and sends the second information to the first terminal, and the second information indicates that the first terminal enters a wireless non-connected state or releases the wireless connection;

[0119] If the wireless access network side device receives third information from the core network side device, and the third information indicates that the first terminal maintains or switches to a wireless connection state, or maintains a wireless connection, the wireless access network side device determines second information according to the third information, and sends the second information to the first terminal, and the second information indicates that the first terminal maintains or switches to a wireless connection state, or maintains a wireless connection;

[0120] If the wireless access network side device receives third information from the core network side device, and the third information indicates that the first terminal is switched to the core network connection state or performs the core network connection establishment process, the wireless access network side device determines second information according to the third information, and sends the second information to the first terminal, and the second information indicates that the first terminal is switched to the core network connection state or performs the core network connection establishment process;

[0121] The process of the wireless access network side device sending the second information to the terminal according to the fifth information is the same as the above-mentioned process of sending the second information to the terminal according to the third information, and will not be repeated herein.

[0122] It should be noted that if the wireless access network device receives the third information and the fifth information, it is necessary to send the second information according to the third information and the fifth information. As an example, the third information indicates that the first terminal maintains or switches to a wireless connection state, and the fifth information indicates that the first terminal enters a wireless non-connection state, or releases the wireless connection, then the wireless access network device sends the second information, and the second information indicates that the first terminal enters a wireless non-connection state, or releases the wireless connection. As another example, the third information indicates that the first terminal maintains or switches to a wireless connection state, and the fifth information indicates that the first terminal maintains or switches to a wireless connection state, then the wireless access network device sends the second information, and the second information indicates that the first terminal maintains or switches to a wireless connection state, or maintains a wireless connection.

[0123] Optionally, in some implementations, if the wireless access network side device does not receive the third information and / or the fifth information within a time agreed upon in the protocol or configured in the network, a default operation is performed.

[0124] As an example, the wireless access network device starts a second timer when it starts sending the first information to the core network device or when it finishes sending the first information to the core network device or after sending the first information to the core network device. The duration of the second timer may be agreed upon by the protocol or configured on the network side.

[0125] During the running of the second timer, if the third information and / or the fifth information is received, the second timer is stopped.

[0126] If the second timer times out, a default operation is performed.

[0127] As another example, the wireless access network device starts a third timer when it starts sending the first information to the core network device or when it finishes sending the first information to the core network device or after sending the first information to the core network device. The duration of the second timer may be agreed upon by the protocol or configured on the network side.

[0128] During the running of the third timer, if the third information or / and the fifth information is received, the third timer is not stopped.

[0129] If the third timer times out, the wireless access network device sends the second information according to the received third information and / or fifth information. If the third timer times out and the wireless access network device does not receive the third information and the fifth information, a default operation is performed.

[0130] In some implementations, the default operation is: sending or refusing to send second information to the terminal, where the second information indicates a connection status operation.

[0131] Optionally, in some embodiments, after receiving the first information from the first terminal and sending or refusing to send the first information to the core network side device, the method further includes: sending second information to the first terminal, where the second information is used to indicate a connection status operation.

[0132] In an embodiment of the present application, the wireless access network side device can directly send second information for indicating the connection status operation to the first terminal after sending the first information to the core network side device, that is, the wireless access network side device does not need to receive the third information and / or the fifth information from the core network side device.

[0133] In another example, the wireless access network device may refuse to send the first information to the core network device. In this case, the wireless access network device may send the second information to the terminal device, or may not send the second information to the terminal. For the case where the wireless access network device sends the second information to the terminal device, as an example, if the wireless access network device does not support the terminal device to only establish a wireless connection (for example, an air interface wireless connection or an RRC connection), the second information may be sent, and the second information indicates a release operation, or the second information may be sent, and the second information indicates a core network connection operation (such as indicating a core network connection operation of the first terminal). As another example, if the wireless access network device supports the terminal device to only establish a wireless connection (for example, an air interface wireless connection or an RRC connection), the second information may be sent, and the second information indicates a connection operation.

[0134] Furthermore, the second information may specifically include at least one of the following:

[0135] (1) indicating a release operation; illustratively, when the second information indicates a release operation, the terminal device enters or switches to a wireless non-connected state, or releases the wireless connection;

[0136] (2) Indicating a connection operation; illustratively, when the second information indicates a connection operation, the terminal device maintains or switches to a wireless connection state, or maintains a wireless connection.

[0137] (3) Indicating a core network connection operation of the first terminal; illustratively, when the second information indicates a core network connection operation of the first terminal, the terminal device switches to a core network connection state, or performs a core network connection establishment process.

[0138] (4) Indicating a release operation of a connection between devices; illustratively, when the second information indicates a release operation of a connection between devices, the terminal (such as the second terminal) enters a wireless non-connected state between devices, or releases the wireless connection between devices.

[0139] (5) Indicating a connection operation of a connection between devices; illustratively, when the second information indicates a connection operation of a connection between devices, the terminal (such as the second terminal) maintains or switches to a wireless connection state between devices, or maintains the wireless connection between devices.

[0140] (6) Instructing the second terminal to perform a core network connection operation. Exemplarily, when instructing the second terminal to perform a core network connection operation, the terminal (such as the second terminal) switches to a core network connection state or performs a core network connection establishment process.

[0141] Optionally, the wireless access network side device may provide the terminal with radio bearer configuration information. The radio bearer configuration information may be used to receive multicast service data. Exemplarily, if the terminal (such as the first terminal) and the base station maintain a connection state, the base station provides the terminal with radio bearer configuration information, such as data radio bearer (such as Data Radio Bearer, DRB) configuration, and the configuration information may be used to receive multicast service data.

[0152] If the core network side device fails to verify the first terminal, sending third information to the wireless access network side device, the third information instructing the first terminal to enter a wireless non-connected state or release the wireless connection;

[0153] If the core network side device successfully verifies the first terminal, third information is sent to the wireless access network side device, where the third information instructs the first terminal to maintain or switch to a wireless connection state, or maintain a wireless connection;

[0154] If the core network side device successfully verifies the first terminal, third information is sent to the wireless access network side device, where the third information instructs the first terminal to switch to a core network connection state or to perform a core network connection establishment process;
