[0035] The following explains the concepts, nouns or coined words involved in the embodiments of the present application.

[0036] 1. Multi-SIM terminal

[0037] Currently, there are not only single-SIM terminals but also dual-SIM or multi-SIM terminals in the market. Dual-SIM and multi-SIM terminals can be collectively referred to as multi-SIM terminals. A multi-SIM terminal refers to a terminal that supports the use of multiple Subscriber Identity Modules (SIMs).

[0038] The capabilities of a multi-SIM terminal can be single transmit and single receive, single transmit and dual receive, and dual transmit and dual receive (Dual-Rx / Dual-Tx), etc.

[0039] One feature of a multi-SIM terminal is that it can camp on multiple networks simultaneously, but the implementation methods of multi-SIM terminals vary. For example, some terminals supporting dual transmit and dual receive can transmit and receive simultaneously on multiple networks without interference, some can transmit and receive simultaneously on multiple networks without interference in specific frequency bands, while in some other frequency bands, there may be band conflicts between multiple SIM cards of a multi-SIM terminal. For example, when the frequency bands on which two SIM cards operate are the same or adjacent, or there are harmonic interference or intermodulation interference, the transmission of one SIM card may interfere with the simultaneous reception of the other SIM card. Therefore, a multi-SIM terminal may adopt a time-division method to transmit and receive data on two networks.

[0040] 2. Multi-Universal Subscriber Identity Module (MUSIM) User Equipment (UE)

[0041] In a multi-SIM terminal, each subscriber identity module can be regarded as a UE, and these UEs can be called MUSIM UEs. For example, the first UE can be a UE in a multi-SIM terminal.

[0042] It should be noted that multiple subscribed entities can be configured on a terminal device. The subscribed entity can be represented by a Subscriber Identity Module (SIM) card. One SIM card corresponds to the subscribed entity of one network. It can be understood that each subscribed entity can correspond to a UE. The SIM card stores the identifier of the subscribed entity, that is, the identifier of the UE, such as the Subscription Permanent Identifier (SUPI), or the International Mobile Subscription Identity (IMSI), etc. Therefore, when multiple SIM cards are inserted or multiple eSIM card information is configured on a terminal, the terminal and different subscribed entities can form different UEs.

[0043] The information transmission method provided in the embodiments of this application can be applied to the scenario where multiple SIMs (MUSIM UEs) in a multi-SIM terminal perform data transmission.

[0044] With the development of communication technology, many terminal devices have the function of supporting multiple SIM cards. One SIM card corresponds to a contracting entity of the network, such as a UE. When one UE of the terminal device is transmitting data, another UE may need to access the network because it needs to transmit signaling or small data. In the related technology, the terminal device will maintain the existing connection and establish a connection with another UE. In this way, the terminal device needs to send and receive data from two UEs at the same time. On the one hand, when the two UEs operate in the same or adjacent frequency bands, the data transmission and reception of one UE may interfere with the data transmission and reception of another UE. On the other hand, since the terminal device needs to transmit and receive data from two UEs, the power consumption of the terminal device is increased. On the other hand, the simultaneous transmission and reception of multiple UEs may cause a large network signaling load, thereby resulting in a large transmission delay.

[0045] The information transmission method provided in the present application is that when a UE (for example, UE 1) of a terminal device is transmitting data, if another UE (UE 2) also needs to transmit signaling or small data, then UE 1 can act as an agent for UE 2 to transmit the signaling or small data of UE 2, that is, UE 1 can act as an agent for UE 2 to transmit the signaling or small data of UE 2, so that UE 2 does not need to transmit the signaling or data by itself. On the one hand, it avoids UE 1 and UE 2 from transmitting information at the same time, thereby avoiding interference between the transmission and reception of one UE and the transmission and reception of another UE. On the other hand, since the terminal device only needs to transmit and receive data on one UE, the power consumption problem of the terminal device is improved. On the other hand, it avoids multiple UEs from transmitting information at the same time, reduces the network signaling load, and thus improves the communication performance.

[0046] The information transmission method provided in the embodiment of the present application is described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

[0047] Figure 2 A flow chart of the information transmission method provided in the embodiment of the present application is as follows: Figure 2 As shown, the information transmission method may include the following steps S201 and S202:

[0048] Step S201: The first UE obtains first configuration information.

[0049] Among them, the above first configuration information includes the relevant configuration for sending or receiving a first message, and this relevant configuration is used to configure the first UE to send or receive the first message at the Radio Resource Control (RRC) layer, Non-Access Stratum (NAS) layer, Radio Link Control (RLC) layer, or Media Access Control (MAC) layer.

[0050] Among them, the above first configuration information includes the relevant configuration for sending or receiving a first message, and the above relevant configuration is used to configure the first UE to send or receive the first message at the RRC layer or NAS layer.

[0051] In some embodiments of the present application, the above first configuration information is pre-configured information, or the above first configuration information is configuration information received from a network-side device.

[0052] Exemplarily, the network-side device may send the first configuration information to the first UE, and the first UE may transmit (i.e., send or receive) the first message according to this first configuration information.

[0053] It should be noted that the transmission in the embodiments of the present application includes at least one of uplink transmission and downlink transmission, that is, the transmission may be at least one of sending and receiving.

[0054] In some embodiments of the present application, the first UE may obtain the first configuration information and transmit the first message according to this first configuration information.

[0055] In some embodiments of the present application, the above first configuration information includes at least one of the following:

[0067] In the embodiments of the present application, the network-side device may send indication information to the first UE to indicate that the first UE is allowed to send or receive a first message to perform the sending or receiving of information of the target UE, so that the first UE can send or receive the information of the target UE when the network-side device allows the first UE to send or receive information on behalf of the target UE, thereby improving the reliability of information transmission.

[0068] In some embodiments of the present application, the identification information of each second UE is used to indicate the UE that is allowed to transmit information through the first message. For example, the identification information of at least one second UE is the C-RNTI identification or 5G-TMSI of at least one second UE.

[0069] In the embodiments of the present application, the network-side device may configure the identification information of the second UE that is allowed to transmit information through the first UE for the first UE, so that the first UE can send or receive information on behalf of the UE according to the identification information of the UE that is allowed to proxy the transmission of information configured by the network-side device, thereby improving the reliability of information transmission.

[0070] In some embodiments of the present application, the second indication information may indicate whether the first UE is allowed to transmit the signaling of the second UE on behalf of the second UE, that is, it indicates whether the first UE is allowed to transmit the signaling of the second UE on behalf of the second UE.

[0071] Exemplarily, the second indication information may indicate that the first UE is allowed to proxy the transmission of the RRC signaling of the second UE.

[0072] In some embodiments of the present application, the above third indication information may indicate whether the first UE is allowed to transmit the data of the second UE on behalf of the second UE, that is, it indicates whether the first UE is allowed to transmit the data of the second UE on behalf of the second UE.

[0073] Exemplarily, the third indication information may indicate that the first UE is allowed to proxy the transmission of the data of the second UE.

[0074] In the embodiments of the present application, the network-side device may send indication information to the first UE to indicate whether the first UE is allowed to send the signaling of the second UE, or indicate whether the first UE is allowed to send the data of the second UE, so that the first UE can, according to the indication of the network-side device, perform the sending or receiving of the signaling of the second UE, or perform the sending or receiving of the data of the second UE, thereby improving the reliability of the transmission.

[0075] In some embodiments of the present application, the above fourth indication information may be used to indicate that the first UE is allowed to send a first message through a target SRB in the RRC connected state.

[0076] In some embodiments of the present application, the above target SRB is a newly defined SRB, and the target SRB may be dedicated to performing proxy transmission, that is, performing the transmission of the data or signaling of other UEs (such as the target UE). Exemplarily, the target SRB may be SRB x, where x may be a natural number greater than 4. For example, the target SRB may be SRB5.

[0077] In some embodiments of the present application, the configuration of the target SRB may include the Packet Data Convergence Protocol (PDCP) configuration of the target SRB, the PDCP re-establishment indication of the target SRB, the PDCP ignore indication of the target SRB, etc.

[0078] It can be understood that each SRB will have a PDCP entity associated with it. At the same time, according to the characteristics of the SRB bearer, one PDCP entity can be associated with one or two Radio Link Control (RLC) entities.

[0079] In some embodiments of the present application, the channel access priority level of the target SRB may characterize the priority of transmitting the target SRB through the DCCH logical channel. Exemplarily, the priority of the target SRB may be represented by a natural number, and the channel access priority level of the target SRB may be lower than any one of SRB0, SRB1, SRB2, SRB3, and SRB4.

[0080] In an embodiment of the present application, the network-side device may configure a target SRB for the first UE to transmit the signaling or data of the target UE, and when the first UE is allowed to use the target SRB to transmit information (such as sending or receiving the data or signaling of the target UE), send indication information to the first UE to indicate that the first UE is allowed to use the target SRB to transmit information, thereby improving the reliability of transmission.

[0081] In some embodiments of the present application, the target logical channel may be a logical channel dedicated to carrying the signaling or data of the target UE.

[0082] In some embodiments of the present application, the priority of the target logical channel may be understood as the priority for the target logical channel to perform the sending or receiving of information. In some embodiments, the priority of the target logical channel may be lower than the priorities of other logical channels.

[0083] In some embodiments of the present application, the target transport channel may be a transport channel dedicated to carrying the signaling or data of the target UE.

[0084] In an embodiment of the present application, the network-side device may configure at least one of a logical channel or a transport channel for the first UE to transmit the signaling or data of the target UE, so that the information of the first UE itself and the information of the target UE can be transmitted through different channels, realizing the isolation of information transmission. Further, when the network-side device allows the first UE to use the logical channel or the transport channel to transmit information (such as sending or receiving the data or signaling of the target UE), it may send indication information to the first UE to indicate that the first UE is allowed to use the logical channel or the transport channel to transmit information, thereby improving the reliability of transmission.

[0085] In some embodiments of the present application, the target MAC control element (CE) may be a MAC CE dedicated to carrying the signaling or data of the target UE.

[0086] In an embodiment of the present application, the network-side device may configure the first UE to transmit the target MAC CE, and when the first UE is allowed to use the target MAC CE to send or receive the data or signaling of the target UE, send indication information to the first UE to indicate that the first UE is allowed to use the target MAC CE to carry the data or signaling of the target UE, thereby improving the reliability of transmission.

[0088] Wherein, the above first message is any one of the following: RRC message, NAS message, RLC data packet, MAC data packet, and the first message includes the signaling or data of the target UE.

[0089] It can be understood that the RRC message is a radio resource control signaling message between the UE and the base station. The NAS message is a signaling message between the UE and the core network device (such as the AMF).

[0092] In some embodiments of the present application, the above step S202 may include the following step S202a or step S202b:

[0093] Step S202a: The first UE sends a first message to the network-side device.

[0094] Step S202b: The first UE receives a first message from the network-side device.

[0095] In some embodiments of the present application, the above network-side device may be a base station or a core network device.

[0096] In some embodiments of the present application, the first message sent by the first UE to the network-side device may be a first uplink message, and the first uplink message carries the uplink signaling or data of the target UE.

[0097] In some embodiments of the present application, the first message sent by the network-side device to the first UE may be a first downlink message, and the first downlink message carries the downlink signaling or data of the target UE.

[0098] In some embodiments of the present application, when the target UE has signaling or data that needs to be sent to the network-side device, the first UE may obtain the signaling or data that the target UE needs to send and send the signaling or data to the network-side device.

[0099] Exemplarily, in the case where the target UE has signaling that needs to be sent to the base station, the first UE may send an RRC message to the base station, and the RRC message carries the signaling of the target UE.

[0100] Exemplarily, in the case where the target UE has NAS data that needs to be sent to the core network device, the first UE may send an NAS message to the base station, and the NAS message carries the NAS data of the target UE.

[0101] In some embodiments of the present application, when there is signaling or data received by the target UE from a network-side device, the first UE may intercept the signaling or data of the target UE from the network-side device, and then send the signaling or data received from the network-side device to the target UE.

[0102] Exemplarily, in the case where the target UE has RRC signaling that needs to be received from the base station, the first UE may receive the RRC signaling from the base station.

[0103] Exemplarily, in the case where the target UE has NAS data that needs to be received from the core network device, the first UE may receive the NAS data from the core network device.

[0104] In the embodiments of the present application, when there is signaling or data that the target UE needs to send or receive, the first UE may proxy the target UE to perform the sending or receiving of the signaling or data, avoiding the simultaneous sending and receiving of data by the target UE and the first UE, thereby reducing the signaling load of the network and improving the communication performance.

[0105] In some embodiments of the present application, the first UE may be a multi-SIM UE, or the first UE may be a UE in a multi-SIM terminal. A multi-SIM terminal can be understood as a terminal with multiple subscriptions, and the first UE is the UE corresponding to the first subscription, where the first subscription is one of the multiple subscriptions.

[0106] In some embodiments of the present application, the first UE and the target UE may be referred to as MUSIM UEs.

[0107] In some embodiments of the present application, the target UE may include at least one of the following: a UE associated with the first UE, a UE in the same multi-SIM terminal as the first UE, a UE to be proxied, a UE in the same cell as the first UE, and a UE in a different cell from the first UE. It can be understood that the target UE is the UE corresponding to other subscriptions except the first subscription among the multiple subscriptions of the terminal (which can also be referred to as a multi-SIM terminal), where the other subscriptions except the first subscription can be one or more subscriptions.

[0108] In some embodiments of the present application, the target UE may include one or more UEs. For example, the target UE may be two MUSIM UEs in a multi-SIM terminal.

[0109] In some embodiments of the present application, the UE associated with the first UE refers to a UE that has established an association relationship with the first UE.

[0110] Exemplarily, after an association relationship is established between two MUSIM UEs in a multi-card UE, one MUSIM UE can transmit signaling or data through the connection of the other MUSIM UE. In this way, multiple MUSIM UEs can be prevented from simultaneously transmitting and receiving, thereby reducing the transmission delay.

[0111] In some embodiments of the present application, the above first message includes at least one of the following pieces of information:

[0112] A first container, which is used to hold the signaling or data of the target UE, and the first container is an RRC container, a NAS container, or a Data container;

[0113] Identification information of the target UE;

[0114] Cell identification information of the cell where the target UE is located.

[0115] In some embodiments of the present application, the above first container is an RRC Container, and the RRC Container contains the RRC signaling of the target UE, or the above first container is a NAS Container, and the NAS Container contains the NAS signaling of the target UE, or the first container is a Data Container, and the Data Container contains the data of the target UE.

[0116] In some embodiments of the present application, the above first container is transparent to the first UE. That the first container is transparent to the first UE can be understood as that the first UE will not parse the data or signaling in the first container, or the data or signaling in the first container is invisible to the first UE.

[0117] In some embodiments of the present application, the RRC signaling, NAS signaling, data, etc. of the target UE contained in the above first container are subject to security operations, such as integrity protection, encryption and decryption, using the security parameters of the target UE.

[0118] In some embodiments of the present application, the RLC data packets, MAC data packets, etc. of the target UE contained in the above first container are subject to security operations, such as integrity protection, encryption and decryption, using the security parameters of the first UE.

[0119] In some embodiments of the present application, if the above first message is an RRC message, the signaling or data of the target UE is contained in the RRC container; or, if the above first message is a NAS message, the signaling or data of the target UE is contained in the NAS container.

[0120] In some embodiments of the present application, the identification information of the target UE includes any one of a Cell-Radio Network Temporary Identifier (C-RNTI), a Full Inactive RNTI (Full I-RNTI), a Short Inactive RNTI (Short I-RNTI), a 5G-Temporary Mobile Subscriber Identity (5G-TMSI), a 5G-S-Temporary Mobile Subscriber Identity (5G-S-TMSI), an International Mobile Subscriber Identification Number (IMSI), a 5G Globally Unique Temporary Identifier (5G-GUTI), and an associated identifier.

[0121] Among them, C-RNTI refers to the identifier of the target UE in the cell. For example, when the target UE and the first UE are in the same cell, the C-RNTI of the target UE can be recognized by the cell. By carrying the C-RNTI in the first message, it is convenient to use this identifier to transmit the information of the target UE through the connection of the first UE when the target UE is in the IDLE state or the RRC-INACTIVE state.

[0122] Full I-RNTI or Short I-RNTI refers to the identifier (ID) of the target UE in the RRC-INACTIVE state. By carrying Full I-RNTI or Short I-RNTI in the first message, it is convenient to use the Full I-RNTI or Short I-RNTI of the target UE to transmit the information of the target UE through the connection of the first UE when the target UE is in the RRC-INACTIVE state.

[0123] 5G-S-TMSI refers to the identifier of the UE in the core network. By carrying 5G-S-TMSI in the first message, it is convenient to use the 5G-S-TMSI of the target UE to transmit the information of the target UE through the connection of the first UE when the target UE is in the IDLE state.

[0124] The IMSI is a sign to distinguish mobile users, stored in the SIM card, and can be used to distinguish the valid information of mobile users. By carrying the IMSI in the first message, it is convenient to use this IMSI to identify and transmit the information of the target UE through the connection of the first UE.

[0125] The association identifier is used to identify the associated UEs. In other words, the association identifier can identify the association relationship between the target UE and the first UE. For example, if UE2 (i.e., the target UE) is associated with UE1 (i.e., the first UE), and UE3 (i.e., the target UE) is associated with UE1, then UE2 and UE3 can be configured with the association identifier. By carrying the association identifier of the target UE in the first message, it is convenient to use this association identifier to transmit the information of the target UE through the connection of the first UE when the target UE is in the IDLE state or the RRC - INACTIVE state.

[0126] In some embodiments of the present application, the first message may include the identifier of the target UE and the cell identifier of the cell where the target UE is located. In this way, combining the cell identifier where the target UE is located with the target UE identifier facilitates the transmission of the information of the target UE, and at the same time, it can also be applicable to the scenario where the target UE and the first UE are in different cells.

[0127] In some embodiments of the present application, the first UE can, in different states, transmit the signaling or data of the target UE in different states through the connection with the network - side device.

[0128] Exemplarily, the above - mentioned first UE may be in the RRC connected state, and the above - mentioned target UE may be in the RRC connected state;

[0129] Or, the first UE may be in the RRC connected state, and the target UE may be in the RRC deactivated state;

[0130] Or, the first UE may be in the RRC connected state, and the target UE may be in the idle state;

[0131] Or, the first UE may be in the RRC deactivated state, and the target UE may be in the RRC deactivated state;

[0132] Or, the first UE may be in the RRC deactivated state, and the target UE may be in the idle state;

[0133] Or, the first UE may be in the idle state, and the target UE may be in the idle state.

[0134] In an embodiment of the present application, when the target UE is in the RRC connected state, the first UE can proxy the transmission of data or signaling of the target UE in the RRC connected state, RRC deactivated state, or idle state, so that the target UE does not need to perform the transmission and reception of data or signaling by itself, thereby avoiding multiple UEs from simultaneously performing data transmission and reception and reducing the signaling load of the network.

[0135] Alternatively, when the target UE is in the RRC deactivated state, the first UE can proxy the transmission of data or signaling of the target UE, so that the target UE does not need to execute the RRC activation process and perform the transmission and reception of data or signaling after RRC activation, but can continue to remain in the deactivated state, thereby reducing the signaling load of the network.

[0136] Alternatively, when the target UE is in the idle state, the first UE can proxy the transmission of data or signaling of the target UE, so that the target UE does not need to establish an RRC connection and perform the transmission and reception of data or signaling after the RRC connection is established, but can continue to remain in the idle state, thereby reducing the signaling load of the network.

[0137] In some embodiments of the present application, if the above target UE is in the RRC connected state, the identification information of the target UE is C-RNTI or 5G-S-TMSI; or, if the target UE is in the deactivated state, the identification information of the target UE is Full I-RNTI or Short I-RNTI or 5G-S-TMSI; or, if the first message is an NAS message, the identification information of the target UE is 5G-S-TMSI.

[0138] In an embodiment of the present application, when the target UE is in the RRC connected state, RRC deactivated state, or idle state, the first UE can carry the identification information of the target UE in different states in the first message, so as to proxy the execution of data or signaling transmission of the target UE when the target RRC is in any state.

[0139] It can be understood that proxying the execution of data or signaling transmission of the target UE means that the first UE transmits the signaling or data of the target UE on behalf of the target UE.

[0140] In some embodiments of the present application, under the condition of meeting the target conditions, the network side device can indicate to allow the transmission of the first message, and the above target conditions include at least one of the following:

[0141] The first UE is configured with a target SRB;

[0142] The first UE supports the transmission of the first message, that is, the first UE has the ability to transmit the first message;

[0143] The first UE is used as a proxy UE;

[0144] The first UE establishes an association with the target UE;

[0145] The first UE is configured with a C-RNTI, a Full I-RNTI, or an association ID;

[0146] The first UE activates AS security;

[0147] The target UE is in the connected state or the RRC deactivated state;

[0148] The target UE is configured with a C-RNTI, a Full I-RNTI, or an association ID;

[0149] The target UE activates AS security.

[0150] Exemplarily, the network side device may send first indication information to the first UE, and the first indication information indicates that the first UE is allowed to send a first message.

[0151] In the embodiments of the present application, when the above target conditions are met, the network side device may indicate that the first UE is allowed to proxy the signaling or data transmission of other UEs, that is, the first UE is allowed to send a first message, so that the first UE can be configured to perform the transmission of the first message when the conditions for proxy transmission are met, improving the reliability of communication.

[0152] In some embodiments of the present application, if the first message is an RLC data packet, the first message is carried on a target logical channel, and the target logical channel is used to carry the signaling or data of the target UE.

[0153] In some embodiments of the present application, the RLC data packet is encrypted and decrypted using the security key of the first UE, so as to facilitate the identification of the sequence number of the RLC data packet.

[0154] In the embodiments of the present application, when the first UE transmits an RLC data packet containing the information of the target UE, the first message may be carried according to the configured target logical channel for transmitting the signaling or data of the target UE, so that the first UE can transmit the RLC layer information of the target UE through a specific logical channel, thereby ensuring the transmission efficiency of the information.

[0155] In some embodiments of the present application, if the first message is a MAC data packet, the first message is carried on a target transport channel or a target MAC control unit, and the target transport channel is used to carry the signaling or data of the target UE.

[0156] In some embodiments of the present application, the target MAC CE may contain the identification information of the target UE, so as to facilitate the first UE to identify the MAC data packet and send it to the target UE.

[0157] In an embodiment of the present application, when the first UE transmits a MAC data packet containing information of the target UE, the MAC data packet can be carried on a target transport channel or a MAC CE configured for transmitting signaling or data of the target UE, so that the first UE can transmit the information of the target UE through a specific transport channel or a specific MAC CE, thereby ensuring the transmission efficiency of the information.

[0158] In some embodiments of the present application, the above-mentioned first message can be carried on a target SRB.

[0159] It should be noted that the explanation of the target SRB can be referred to the description of the above embodiments, and will not be elaborated here.

[0160] In some embodiments of the present application, when the first condition is satisfied, the above-mentioned first message is carried on a target SRB. Among them, the above-mentioned first condition includes at least one of the following:

[0161] The first UE activates access stratum (AS) security.

[0162] The network side device configures a target SRB;

[0163] The network side device configures a target logical channel;

[0164] The network side device configures a target transport channel.

[0165] Exemplarily, after the AS security is activated, the first UE can transmit the first message through the target SRB, thereby ensuring the security of the first message.

[0166] Exemplarily, when the first UE is configured with a target SRB, the first message is transmitted through the target SRB, thereby ensuring the reliability of the transmission.

[0167] Exemplarily, when the first UE is configured with a target logical channel, an RLC data packet containing data or signaling of the target UE is transmitted through the target logical channel.

[0168] Exemplarily, when the first UE is configured with a target transport channel or a target MAC CE, the MAC layer data or signaling of the target UE is carried on the target logical channel or the target MAC CE.

[0169] In some embodiments of the present application, the above-mentioned target SRB satisfies at least one of the following:

[0170] The target SRB is transmitted through a dedicated control channel (DCCH).

[0171] The channel access priority of the target SRB is lower than that of SRB0, SRB1, SRB2, or SRB3.

[0172] Exemplarily, the first UE may bear the signaling and data that the target UE needs to send through the target SRB, and transmit the target SRB through the DCCH, so as to ensure the transmission rate of the signaling or data.

[0173] Exemplarily, the first UE may transmit the signaling or data that the target UE needs to send through the target SRB with a lower channel access priority, so as to ensure that the signaling or data of the first UE can be transmitted preferentially.

[0174] In some embodiments of the present application, the transmission channel or channel access priority of the above target SRB is configured by the network-side device through an RRC reconfiguration message.

[0175] In an embodiment of the present application, the first UE may obtain first configuration information, which is related to the configuration of sending or receiving a first message, and is used to configure the first UE to send or receive the first message at the RRC layer, NAS layer, RLC layer, or MAC layer. Based on the first configuration information, the first UE sends or receives the first message. Through this method, the first UE may transmit the signaling or data of the target UE through an RRC message, NAS message, RLC data packet, or MAC data packet based on the related configuration of sending or receiving the first message, so that the target UE does not need to perform signaling or data transmission by itself, avoiding multiple UEs from transmitting information simultaneously, reducing the signaling load of the network, and thus improving communication performance.

[0176] In some embodiments of the present application, the above step S202 may include the following step S202c or step S202d:

[0177] Step S202c: When the target SRB has been established, the first UE sends or receives the first message through the target SRB.

[0178] Step S202d: When the target SRB has not been established, the first UE sends the first message through another established SRB.

[0179] In some embodiments of the present application, the above-mentioned other established SRB may be any one of SRB0, SRB1, SRB2, SRB3, and SRB4 established by the first UE.

[0180] Exemplarily, if the target SRB (such as SRB x) has been established, the first UE sends the first uplink message through the target SRB; if the network-side device has not established the target SRB, the first UE sends the first uplink message through another established SRB such as SBR1 or SRB2.

[0181] In an embodiment of the present application, when the target SRB has been established, the UE may preferentially use the target SRB to send an uplink message. Alternatively, when the target SRB has not been established, the UE may send an uplink message through another established SRB, thereby ensuring the efficiency of proxy transmission.

[0182] In some embodiments of the present application, the above information transmission method may include the following step S203:

[0183] Step S203: When the target SRB has not been established, the first UE does not send or receive the first message.

[0184] In some embodiments of the present application, before the above step S201, the information transmission method provided by the embodiment of the present application may include the following step S204:

[0185] Step S204: The first UE sends a second message to the network side device.

[0186] Wherein, the above second message includes at least one of the following:

[0187] Transmission request information, which is used to request to send or receive the first message;

[0188] Message transmission preference information, which is used to indicate the transmission preference of the first UE for transmitting the first message;

[0189] Establishment request information, which is used to request to establish the target SRB.

[0190] In some embodiments of the present application, the above transmission request information may be used to request to transmit the signaling or data of the target UE through the first message, and the identification information of the target UE may be included in the above transmission request information. Further, after receiving the transmission request information from the first UE, the network side device may send a transmission request response to indicate that the first UE is allowed to transmit the first message.

[0191] In some embodiments of the present application, the above message transmission preference information may be sent through UE assistance information. Further, after receiving the message transmission preference information from the first UE, the network side device may send indication information to indicate that the first UE is allowed to transmit the first message.

[0192] In some embodiments of the present application, the above transmission preference information indicates that the first UE prefers to transmit the first message, that is, prefers to transmit the signaling or data of the target UE.

[0193] In some embodiments of the present application, the above-mentioned establishment request information may be sent through an RRC message. Further, after receiving the establishment request information from the first UE, the network-side device may establish a target SRB for the first UE to perform proxy transmission.

[0194] In some embodiments of the present application, after the first UE sends a second message to the network-side device, the network-side device may send the above-mentioned first configuration information to the first UE to configure the first UE to transmit the first message.

[0195] It should be noted that the above step S204 may be executed before the above step S201.

[0196] In the embodiments of the present application, the first UE may send transmission request information or message transmission preference information to the network-side device to request to perform signaling or data transmission on behalf of the target UE. The network-side device may, according to the request of the first UE, indicate to allow the first UE to transmit the signaling or data of the target UE. Alternatively, the first UE may send a target SRB establishment request to the network-side device, and the network-side device establishes a target SRB or provides a transmission channel for transmitting the first message according to the request of the first UE, avoiding configuring UEs without such a requirement, thereby saving network resources.

[0290] Embodiment 1: Both the first UE and the target UE are in the RRC connected state. Exemplarily, the above - mentioned information transmission method may include the following steps S11 and S12:

[0291] Step S11: When the target UE has signaling or data to be transmitted, the first UE sends a first uplink message to the network - side device.

[0292] Among them, the first uplink message carries the uplink signaling or data of the target UE.

[0293] In some examples, the above - mentioned first uplink message includes at least one of the following:

[0307] Step S21: When the target UE has signaling or data to transmit, the first UE sends a first uplink message to the network.

[0308] Wherein, the first uplink message carries the uplink signaling or data of the target UE.

[0309] In some examples, the first uplink message includes at least one of the following:

[0310] The Full I-RNTI or Short I-RNTI of the target UE;

[0319] Embodiment 3: The first UE is in the RRC connected state or the RRC deactivated state, and the target UE is in the RRC connected state, the RRC deactivated state or the idle state. Exemplarily, the above information transmission method may include the following steps S31 and step S32:

[0333] In some examples, the first UE and the target UE are UEs in the same multi-SIM terminal, and the first UE and the target UE are in the same cell.

[0334] In the embodiments of the present application, by borrowing the connection of the first UE to transmit the signaling and data of the target UE, it is possible to avoid the simultaneous transmission of the first UE and the target UE, reduce the cost of the multi-SIM terminal, and contribute to the energy saving of the terminal. On the other hand, using NAS messages for signaling or data transmission facilitates the selection of an appropriate transmission channel based on the service. For example, only signaling or small data selects the above first uplink and downlink messages for transmission.

[0339] In some examples, the first UE may send the first uplink message according to the first configuration information.

[0340] In some examples, if the target SRB has been established, the first UE sends the first uplink message through the target SRB.

[0341] In some examples, if the network has not established the target SRB, the UE sends the first uplink message through other established SRBs such as SBR1, SRB2, etc., or if the network has not established the target SRB, the first UE is not allowed to send the first uplink message.

[0342] It should be noted that the above steps S41 and step S42 may be executed before the above steps S11, step S21 or step S31.

[0350] Step S52: The first UE receives first configuration information from the network device.
