Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

In the MUCC (Multiple UEs Cooperative Communication) technology, when an eNB (evolved NodeB, base station) communicates with a certain UE (User Equipment, user equipment), it can directly communicate with the UE in the traditional way, or It is possible to communicate with another UE in the vicinity of the UE to cause the other UE to forward the data of the UE. The two UEs may communicate through an SRC (Short Range Communication, short-range communication) manner, such as Bluetooth, WiFi (Wireless Fidelity, wireless fidelity), and the like. In this way, the UE with the best channel condition can be selected from some UEs to transmit uplink and downlink data, so as to achieve the effect of multi-user diversity. The UE that plays a forwarding role in the middle is an S-UE (Supporting UE, supporting user equipment), and the destination UE is called a B-UE (Benefitted UE, beneficiary user equipment). One S-UE may have multiple B-UEs, and conversely, one B-UE may also have multiple S-UEs. A UE can act as either a B-UE or an S-UE.

An embodiment of the present invention provides a method for connection initial signaling, as shown in FIG. 1 , including:

101. The beneficiary device receives a broadcast message sent by the support device, and accesses the support device according to the broadcast message to obtain an IP address allocated by the support device.

Exemplarily, the benefited device B-UE and the supporting device S-UE may be user equipment such as a mobile phone. Before the B-UE receives the broadcast message sent by the S-UE, the S-UE attaches to the MME (Mobility Management Entity) corresponding to the S-UE, which is represented by the S-MME, and the S-MME is the S-UE The bearer and context information on the core network side are established. Then, the S-UE sends a broadcast message to the B-UE, and the broadcast message includes the SRC id (identity) of the S-UE for short-range communication, so that when the B-UE receives the SRC id, the SRC id is used to pass the SRC method. After accessing the S-UE, the S-UE allocates an internal IP (Internet Protocol, Internet Protocol) address to the accessed B-UE, so that the B-UE communicates with the S-UE through the IP address.

102. The beneficiary device sends a radio resource control RRC message to the support device through the IP address, so that the support device sends an uplink RRC message to the base station, so that the base station and the mobility management entity corresponding to the beneficiary device establish a core network side bearer and context information for the beneficiary device , the uplink RRC message includes an RRC message.

Specifically, after obtaining the IP address, the B-UE can use the IP address to send an RRC message to the S-UE through the SRC method. The RRC message may include the GUTI (Globally Unique Temporary UE Identity) of the B-UE. temporary UE identifier), so that the MME corresponding to the B-UE can identify the B-UE through the identifier. When the S-UE receives the RRC (Radio Resource Control, radio resource control) message, the S-UE sends an uplink RRC message to the eNB, where the uplink RRC message includes the RRC message sent by the B-UE to the SUE. The RRC message includes a NAS (Non AccessStratum, non-access stratum) message of the B-UE.

After receiving the uplink RRC message sent by the S-UE, the eNB obtains the RRC message sent by the B-UE to the S-UE from the uplink RRC message, and extracts the NAS message of the B-UE in the RRC message. The NAS message is sent to the MME corresponding to the B-UE, and is represented by B-MME. The B-MME establishes a core network side bearer for the B-UE, and establishes context information for the B-UE on the eNB.

Among them, when the S-UE receives the RRC message sent by the B-UE, the S-UE may be in an idle state or in a connected state. Considering this situation, the B-UE sends the RRC message to the S-UE through the IP address. Before the message, the B-UE learns that the S-UE is in a connected state, or learns that the S-UE is not connected to the eNB and is in an idle state.

Specifically, the B-UE sends a request message to the S-UE, and when the S-UE is connected to the eNB and is in the connected state, the B-UE receives the response message returned by the S-UE; When in the idle state, the B-UE receives the response message returned by the S-UE. The response message is when the S-UE sends an RRC connection request message to the eNB and triggers the eNB to send an initial message to the mobility management entity corresponding to the S-UE. It is sent after the mobility management entity corresponding to the S-UE establishes the bearer and context information for the S-UE.

Alternatively, the B-UE receives the response message returned by the S-UE, and the RRC connection request message includes the request message, and the response message is included in the RRC connection response message. The response message is after the S-UE sends an RRC connection request message to the eNB, the eNB sends an initial message to the mobility management entity corresponding to the S-UE, and the mobility management entity corresponding to the S-UE establishes the bearer and context information for the S-UE. sent.

The request message or response message can be an RRC message, or can be a message in other special format, which can be preset on the S-UE and B-UE, for example, a bit "1" is set on the B-UE " is the format of the request message, and the response message is three bits. "111" is the response message.

Alternatively, after the S-UE receives the RRC message sent by the B-UE through the IP address, the S-UE establishes a connection with the eNB.

Specifically, when the S-UE is connected to the eNB and is in a connected state, the S-UE sends an uplink RRC message to the eNB; or, when the S-UE is not connected to the eNB and is in an idle state, the S-UE sends an RRC connection to the eNB The request message triggers the eNB to send an initial message to the MME corresponding to the S-UE, that is, the S-MME, so that the S-MME establishes bearer and context information for the S-UE. The RRC connection request message includes the S-TMSI (SAE (System Architecture Evolution)-Temporary MobileSubscriber Identity, System Architecture Evolution-Temporary Mobile Subscriber Identity) of the S-UE, and the initial message also includes the S-UE of the S-UE -TMSI, in this way, after receiving the S-TMSI initial message including the S-UE sent by the eNB, the S-MME can establish the core network side bearer and context information for the S-UE. In this way, when the S-UE is connected to the eNB in a connected state, the S-UE sends an uplink RRC message to the eNB. The uplink RRC message includes the RRC message received by the S-UE from the B-UE.

103. The beneficiary device receives the RRC connection reconfiguration message sent by the support device, and the RRC connection reconfiguration message is sent after the support device configures and synthesizes a protocol stack carried on the support device side for the beneficiary device and receives the downlink RRC message sent by the base station. Yes, the downlink RRC message includes an RRC connection reconfiguration message, so that single-link multi-user equipment composite communication is performed between the beneficiary device and the supporting device.

Specifically, after the B-MME completes the establishment of the core network side bearer and context information for the B-UE, the eNB configures the single-link MUCC for the S-UE and the B-UE, that is, configures the S-UE and the B-UE respectively The protocol stack on the eNB side. Then, the eNB sends an RRC connection reconfiguration message to the S-UE, so that the S-UE configures the B-UE to synthesize the protocol stack carried on the S-UE side. The eNB wraps the RRC connection reconfiguration message for the B-UE in the downlink RRC message from the eNB to the S-UE, and the eNB sends the downlink RRC message to the S-UE. reconfiguration message, the S-UE sends the RRC connection reconfiguration message to the B-UE through SRC. In this way, after the S-UE receives the RRC connection reconfiguration message from the B-UE, the establishment of the single-link MUCC between the S-UE and the B-UE is completed, and the B-UE can send data to the eNB through the single-link MUCC , that is, the B-UE can communicate with the eNB through the S-UE forwarding data.

An embodiment of the present invention provides a method for connecting initial signaling, receiving a broadcast message sent by a support device through a beneficiary device, and accessing the support device according to the broadcast message to obtain an IP address allocated by the support device, and the beneficiary device sends the support device through the IP address to the support device. The device sends a radio resource control RRC message, so that the support device sends an uplink RRC message to the base station, so that the base station and the mobility management entity corresponding to the beneficiary device establish a core network side bearer and context information for the beneficiary device. The uplink RRC message includes the RRC message. The base station configures the protocol stack on the base station side for the beneficiary device and the support device respectively, and after the support device configures the beneficiary device with a protocol stack carried on the support device side, when the support device receives the downlink RRC message sent by the base station, the beneficiary device receives the The RRC connection reconfiguration message sent by the support device, the downlink RRC message includes the RRC connection reconfiguration message, the single-link multi-user equipment composite communication is successfully established between the beneficiary device and the support device, which enables the B-UE to connect to the eNB without , a single-link MUCC can be established.

In this way, when the S-UE is connected to the eNB in a connected state, the S-UE sends an uplink RRC message to the eNB. The uplink RRC message includes the RRC message received by the S-UE from the B-UE.

Or, for the case that the S-UE may be in the idle state or the connected state, before the S-UE receives the first RRC message sent by the B-UE through the IP address, the S-UE informs the B-UE that the S-UE is in the connected state .

Specifically, the S-UE receives the request message sent by the B-UE, and when the S-UE is connected to the eNB and is in a connected state, the S-UE sends a response message to the B-UE, so that the B-UE can know that the S-UE is connected state.

Or when the S-UE is not connected to the eNB and is in an idle state, the S-UE returns a response message to the B-UE. The mobility management entity sends the initial message, so that the mobility management entity corresponding to the S-UE sends it after establishing the bearer and context information for the S-UE; or, the S-UE returns a response message to the B-UE, and the RRC connection request message includes the request message, the response message is included in the RRC connection response message, the response message is when the S-UE sends the RRC connection request message to the eNB, and the eNB sends the initial message to the MME corresponding to the S-UE, and the MME corresponding to the S-UE is Sent after the S-UE establishes bearer and context information.

Alternatively, before the B-UE sends a radio resource control RRC message to the S-UE, the eNB establishes a connection with the S-UE.

Specifically, when the B-UE sends a request message to the S-UE, and the S-UE has no connection with the eNB and is in an idle state, the eNB receives the RRC connection request message sent by the S-UE, and the eNB receives the RRC connection request message sent by the S-UE. After the connection request message, an initial message is sent to the mobility management entity corresponding to the S-UE, so that after the mobility management entity corresponding to the S-UE establishes bearer and context information for the S-UE, the S-UE returns a response message to the B-UE .

Or, when the B-UE sends a radio resource control RRC message to the S-UE, and the S-UE has no connection with the eNB and is in an idle state, the eNB receives the RRC connection request message sent by the S-UE, and the RRC connection request message includes a request message, The eNB sends an initial message to the mobility management entity of the S-UE, so that the mobility management entity corresponding to the S-UE establishes bearer and context information for the S-UE, and then the eNB returns an RRC connection response message to the S-UE, so that the S-UE The UE returns a response message to the B-UE, and the response message is included in the RRC connection response message.

The request message sent by the B-UE to the S-UE or the response message sent by the S-UE to the B-UE may be an RRC message or a special agreement between the UEs. It is pre-set on the UE, for example, one bit "1" is set on the B-UE as the format of the request message, and the response message is three bits "111" as the response message, which is not limited here.

302. The base station establishes a core network side bearer and context information for the beneficiary device through the mobility management entity corresponding to the beneficiary device according to the second RRC message.

Specifically, since the first RRC message sent by the B-UE to the S-UE includes the NAS message of the B-UE, and the second RRC message sent by the S-UE to the eNB includes the NAS message of the B-UE, the eNB will The NAS message of the B-UE is extracted from the received second RRC message, and the NAS message is sent to the B-MME, and the B-MME establishes a core network side bearer for the B-UE according to the NAS message, and is on the eNB The B-UE establishes context information.

303. The base station configures a protocol stack on the base station side for the support device and the benefited device respectively.

304. The base station sends a first RRC connection reconfiguration message to the support device, so that the support device configures and synthesizes a protocol stack carried on the support device side for the beneficiary device.

Specifically, after the B-MME establishes the core network side bearer and context information for the B-UE, the eNB configures the single-link MUCC for the S-UE and the B-UE, that is, configures the S-UE and the B-UE respectively The protocol stack on the base station side, and then the eNB sends the first RRC connection reconfiguration message to the S-UE, so that the S-UE configures the B-UE to synthesize the protocol stack carried on the supporting device side.

305. The base station sends a third RRC message to the support device, so that the support device parses the third RRC message, obtains the second RRC connection reconfiguration message sent by the base station to the beneficiary device, and sends the second RRC connection reconfiguration message to Benefit equipment.

Specifically, after the S-UE establishes a composite bearer corresponding to the bearer for the B-UE, the eNB wraps the second RRC connection reconfiguration message for the B-UE in the third RRC message from the eNB to the S-UE, and the eNB sends the S-UE a second RRC connection reconfiguration message. - The UE sends a third RRC message, the third RRC message includes the second RRC connection reconfiguration message to be sent by the eNB to the B-UE, and the S-UE parses the received third RRC message to obtain the second RRC message included in it. RRC connection reconfiguration message, and the second RRC connection reconfiguration message is sent to the B-UE by means of SRC.

306. The base station establishes single-link multi-user equipment composite communication between the benefited device and the supporting device.

An embodiment of the present invention provides a connection initial signaling method. After a benefited device sends a first radio resource control RRC message to a support device, the base station receives a second RRC message sent by the support device, where the second RRC message includes the first RRC message , the base station establishes the core network side bearer and context information for the beneficiary device through the mobility management entity corresponding to the beneficiary device according to the second RRC message, the base station configures the base station side protocol stack for the support device and the beneficiary device respectively, and sends the first An RRC connection reconfiguration message enables the support device to configure and synthesize the protocol stack carried on the support device side for the beneficiary device, and the base station sends a third RRC message to the support device, so that the support device parses the third RRC message and obtains the information that the base station sends to the support device. The second RRC connection reconfiguration message of the beneficiary device, and the second RRC connection reconfiguration message is sent to the beneficiary device. On the premise of connecting to the eNB, a single-link MUCC can be established.

Yet another embodiment of the present invention provides a method for connection initial signaling, as shown in FIG. 4 , including:

401. The support device is connected to a mobility management entity corresponding to the support device, so that the mobility management entity corresponding to the support device establishes a core network side bearer and context information for the support device.

Specifically, when the S-UE is attached (attached) to the S-MME, the S-MME establishes the core network side bearer and context information for the S-UE.

Among them, the MME is the control node that handles the signaling interaction between the UE and the core network. Its main functions include saving the UE's mobility management context information, such as the user's identity, mobility management status, location information, etc., and processing NAS signaling. , responsible for the security of NAS signaling, etc.

402. The supporting device sends a broadcast message to the beneficiary device.

Specifically, after the S-MME establishes the core network side bearer and context information for the S-UE, the S-UE sends a broadcast message to the B-UE, and the broadcast message may include the short-range communication between the S-UE and the B-UE. SRC id. Wherein, the SRC may be technologies such as Bluetooth and WiFi.

403. The beneficiary device accesses the support device according to the broadcast message, and obtains the IP address allocated by the support device.

Specifically, after receiving the SRC id sent by the S-UE, the B-UE can access the S-UE in the SRC mode according to the id, and the S-UE allocates an internal IP address to the B-UE, and assigns the allocated IP address to the B-UE. The address is sent to the B-UE, so that the B-UE communicates with the S-UE through the IP address.

404. The beneficiary device sends a radio resource control RRC message to the supporting device through the IP address.

Specifically, after the B-UE receives the IP address sent by the S-UE, the B-UE sends an RRC message to the S-UE in an SRC manner according to the IP address. The RRC message may include the GUTI of the B-UE, so as to facilitate the The MME corresponding to the B-UE can identify the B-UE through the GUTI.

405. The support device sends an uplink RRC message to the base station.

Exemplarily, after the S-UE receives the RRC message sent by the B-UE through the IP address, if the S-UE is connected to the eNB and is in a connected state, the S-UE sends an uplink RRC message to the eNB, and the The interaction is shown in Figure 5; if the S-UE is not connected to the eNB and is in an idle state, the S-UE sends an RRC connection request message to the eNB, so that the eNB sends an initial message to the MME corresponding to the S-UE, that is, the S-MME. Make the S-MME establish bearer and context information for the S-UE. The RRC connection request message includes the S-TMSI of the S-UE, and the initial message also includes the S-TMSI of the S-UE. In this way, the S-MME receives the S-TMSI including the S-UE sent by the eNB. After the initial message, the core network side bearer and context information can be established for the S-UE. In this way, when the S-UE is connected to the eNB in a connected state, the S-UE sends an uplink RRC message to the eNB. The uplink RRC message includes the RRC message received by the S-UE from the B-UE, and the interaction between the devices is shown in FIG. 6 .

Or, for the case that the S-UE may be in an idle state or a connected state, optionally, before the S-UE receives the radio resource control RRC message sent by the B-UE through the IP address, the S-UE receives the RRC message sent by the B-UE. A request message is used to facilitate the B-UE to establish a connection with the S-UE. When the S-UE is connected to the eNB and is in the connected state, the S-UE sends a response message to the B-UE so that the B-UE can know that the S-UE is connected. state; when the S-UE is not connected to the eNB and is in an idle state, the S-UE sends an RRC connection request message to the eNB, so that the eNB sends an initial message to the mobility management entity corresponding to the S-UE, so that the S-UE corresponding The mobility management entity establishes bearer and context information for the S-UE, and the S-UE sends a response message to the B-UE, so that the B-UE can know that the S-UE is in a connected state. Then, the S-UE receives the radio resource control RRC message sent by the B-UE through the IP address, and the interaction between the devices is shown in FIG. 7 .

The request message sent by the B-UE to the S-UE may be an RRC message, or may be a special agreement between the UEs, which is not limited here. The RRC connection request message may include the S-TMSI of the S-UE. After receiving the RRC connection request message, the eNB wraps the S-TMSI of the S-UE in the connection request message in the initial message, and sends a message to the S-UE The MME sends an initial message containing the S-TMSI of the S-UE so that the S-MME can establish bearer and context information for the S-UE.

Or, for the case that the S-UE may be in an idle state or a connected state, before the S-UE receives the RRC message sent by the B-UE through the IP address, the S-UE receives the request message sent by the B-UE, so that the B-UE The UE establishes a connection with the S-UE. When the S-UE is connected to the eNB and is in the connected state, the S-UE returns a response message to the B-UE so that the B-UE can know that the S-UE is in the connected state;

When the S-UE is not connected to the eNB and is in an idle state, the S-UE sends an RRC connection request message to the eNB. - The MME sends an initial message so that the mobility management entity corresponding to the S-UE can establish bearer and context information for the S-UE. Then, the S-UE receives the RRC connection response message returned by the eNB. The connection response message includes the response message returned by the eNB to the B-UE, so that the S-UE can send the response message to the B-UE. The interaction between the devices is shown in Figure 8 shown.

The request message sent by the B-UE to the S-UE may be an RRC message or a special agreement between the UEs, which is not limited here. The RRC connection request message includes not only the request message sent by the B-UE to the S-UE, but also the S-TMSI of the S-UE. After receiving the RRC connection request message, the eNB will The S-TMSI packet of the S-UE sends an initial message including the S-TMSI of the S-UE to the S-MME in the initial message, so that the S-MME can establish bearer and context information for the S-UE. Then, the eNB wraps the response message to the B-UE in the RRC connection response message from the eNB to the S-UE, and sends the RRC connection response message to the S-UE, and then the S-UE sends the response from the eNB to the B-UE. The message is sent to the B-UE so that the B-UE knows that the S-UE is in the connected state and continues to connect with the S-UE in the initial signaling. The response message that the eNB will send to the B-UE may be an RRC message, or may be other agreements, which are not limited here.

In the idle state, the UE receives the system information broadcast by the eNB, and the MME will assign an identifier to independently identify the UE in a tracking area, and the eNB does not store the RRC context information of the UE. When the UE is in the connected state, the UE establishes an RRC connection. The eNB stores the context information of the UE. The eNB knows the cell to which the UE belongs. The network can send and receive data between the UE and the network. The network controls the mobility process, such as handover, and the eNB controls the It is implemented to configure the DRX (Discontinuous Reception, discontinuous reception) period according to the activation level of the UE, so as to facilitate the UE to save power and utilize resources effectively. When the UE is in a connected state, it can be divided into a synchronized state and an out-of-gait state. Wherein, when the UE is in the connection synchronization state, it can send uplink data to the eNB, and when the UE is in the connection out-of-sync state, it cannot send uplink data to the eNB except for initiating random access. To recover from the out-of-gait state to the synchronized state, the UE needs to initiate random access.

406. The base station establishes a core network side bearer and context information for the beneficiary device through the mobility management entity corresponding to the beneficiary device according to the uplink RRC message, and the uplink RRC message includes the RRC message.

Exemplarily, since the eNB receives the uplink RRC message from the S-UE includes the RRC message sent by the B-UE to the S-UE, the RRC message includes the NAS message of the B-UE, and the eNB receives the uplink RRC message. Then, the NAS message of the B-UE is extracted from the uplink RRC message, and the NAS message is sent to the MME corresponding to the B-UE, namely the B-MME, and the B-MME establishes a core for the B-UE according to the NAS message. The network side bearer is established, and the core network side bearer and context information are established for the B-UE on the eNB.

When the eNB does not find the MME corresponding to the B-UE, the eNB selects a suitable new MME for the B-UE, and sends the GUTI in the NAS message of the B-UE to the new MME.

407. The base station configures a protocol stack on the base station side for the benefited device and the supporting device respectively.

Specifically, after the B-MME establishes the core network side bearer and context information for the B-UE, the eNB configures the single-link MUCC for the S-UE and the B-UE, that is, configures the S-UE and the B-UE respectively The protocol stack on the base station side.

Among them, the granularity of MUCC technology application is a bearer, and the bearer is used to transmit control signaling on the control plane, and transmit service parameters on the user plane. When a bearer is established on the B-UE and MUCC is expected to be applied on the bearer, the S-UE has a composite bearer corresponding to the bearer, and the composite bearer established on the S-UE is only for the B-UE. Instead of transmitting the S-UE's own data. Correspondingly, the eNB also establishes two corresponding composite bearers for the bearer on the B-UE and the composite bearer on the S-UE.

In addition, the protocol stack of the MUCC technology is different from the traditional LTE (Long Term Evolution) protocol stack. A synthesis layer needs to be added to the protocol stack. The synthesis layer can be added in different positions, such as in PDCP ( On the Packet Data Convergence Protocol) layer, it can also be added between the PDCP layer and the RLC (Radio Link Control, Radio Link Control) layer, etc.

Exemplarily, taking the composite layer between the PDCP layer and the RLC layer as an example, in the case of uplink data transmission, when the MUCC technology is used to send the uplink data, the main functions of the composite layer on the B-UE are packet offloading and transmission. The SRC method transmits the data packet to the S-UE. In order to distinguish which composite bearer on the S-UE the data packet belongs to, some header information is added to the data packet. The main function of the composite layer on the S-UE is to map each packet received from the B-UE through the SRC method to a composite bearer on the S-UE according to the packet header information added on the S-UE composite layer. .

Among them, at the sending end, each layer receives SDU (Service Data Unit, service data unit) from the upper layer, and outputs PDU (Protocol Data Unit, protocol data unit) to the lower layer. For example, the RLC layer receives packets from the PDCP layer, which are PDCP PDUs from the PDCP perspective and RLC SDUs from the RLC perspective. The RLC layer generates and provides the MAC (Medium Access Control, medium access control) layer. Packets, these packets passed to the MAC are RLC PDUs from the RLC perspective, and MAC SDUs from the MAC perspective. At the receiving end, the process is reversed, each layer sends SDUs to the upper layer, and the upper layer receives them as PDUs.

In this way, on the B-UE, the PDCP SDU enters the PDCP layer, outputs the PDCP PDU, enters the synthesis layer, and sends the PDCP PDU to the S-UE by means of SRC. The S-UE maps the PDCP PDU to the corresponding composite bearer, and then continues to enter the RLC layer of the composite bearer, outputs the RLC PDU, and then enters the MAC layer and the PHY (Physical Layer, physical layer), and then sends it to the eNB. The data received by the eNB goes through the PHY layer and the MAC layer into a MAC SDU, and then enters the synthetic bearer corresponding to the S-UE on the eNB. After passing through the RLC layer, it is mapped to the bearer corresponding to the B-UE on the eNB and enters the PDCP layer. , which is combined with the data of the bearer sent by the B-UE and aggregated together.

The protocol stack of the single-link MUCC is similar to that of the general MUCC, except that the B-UE can only communicate with the combined bearer of the S-UE, and cannot communicate with the eNB directly.

408. The base station sends an RRC connection reconfiguration message to the support device, so that the support device configures and synthesizes a protocol stack carried on the support device side for the beneficiary device.

Specifically, after the eNB configures the protocol stacks on the base station side for the B-UE and the S-UE, respectively, the eNB sends an RRC connection reconfiguration message to the S-UE, so that the S-UE configures the B-UE for the combined bearer on the support device side. the protocol stack.

409. The base station sends a downlink RRC message to the support device, where the downlink RRC message carries an RRC connection reconfiguration message to be sent by the base station to the beneficiary device.

Specifically, after the S-UE establishes a composite bearer for the B-UE, the eNB wraps the RRC connection reconfiguration message for the B-UE in the downlink RRC message from the eNB to the S-UE, and then the eNB sends the S-UE to the S-UE. A downlink RRC message, where the downlink RRC message includes an RRC connection reconfiguration message from the eNB to the B-UE.

410. The support device sends the RRC connection reconfiguration message to the beneficiary device, and the establishment of the single-link multi-user equipment composite communication between the support device and the beneficiary device is completed.

Specifically, when the S-UE receives the downlink RRC message sent by the eNB, the downlink RRC message includes the RRC connection reconfiguration message sent by the eNB to the B-UE, and the S-UE sends the RRC connection reconfiguration message through SRC. For the B-UE, in this way, the establishment of the single-link MUCC between the S-UE and the B-UE is completed, and the B-UE can send data through the established single-link MUCC with the S-UE as the intermediate turn to the eNB.

In this way, when the S-UE can connect to the eNB normally, the channel quality between the B-UE and the eNB is not good, or the eNB cannot cover the B-UE and the B-UE cannot connect to the eNB normally, the B-UE does not need to communicate with the eNB. When the eNB establishes a connection for direct communication, it can also establish a single-link MUCC with a nearby S-UE, so as to communicate with the eNB by means of a composite bearer on the S-UE. That is, the single-link MUCC is completed through the agent of the S-UE, and the gait is entered. At the same time, when the B-UE moves out of the coverage of the S-UE, it can first consider restoring uplink synchronization with the eNB without first initiating re-establishment, and at the same time, the coverage of the eNB is also increased.

As shown in Figure 9, it is a schematic diagram of control signaling transmission in the control plane protocol stack before the establishment of a single-link MUCC. Figure 10 is a schematic diagram of control signaling transmission in the control plane protocol stack after the establishment of a single-link MUCC. Figure 11 The schematic diagram of data transmission in the user plane protocol stack after the establishment of the single-link MUCC is similar to the schematic diagram of data transmission in the user plane protocol stack before the establishment of the single-link MUCC.
