In the deployment process of the fifth generation mobile communication system (5G) network, the 5G cell can be used as a macro-coverage independent network, or as a small cell to cover and capacity an existing Long Term Evolution (LTE, Long Term Evolution) network. enhanced. No matter which networking method is adopted, the dual-connection technology can be used to realize the interconnection of the LTE system and the 5G system, thereby improving the radio resource utilization of the entire mobile network system, reducing the delay of system handover, and improving user and system performance. The embodiment of the present invention is applicable to a dual-connection application scenario in which a terminal connects to a master node and a secondary node, especially an EN-DC scenario. Of course, the embodiment of the present invention is also applicable to a multi-connection application scenario in which a terminal connects to multiple nodes.

Taking the EN-DC scenario as an example, in EN-DC, the master node is the evolved base station (eNB) in the LTE system, the secondary node is the (gNB) in the 5G system, and the control plane accesses the evolved core network (EPC) through the eNB. , Evolved Packet Core).

The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

The embodiment of the present invention provides a method for determining an uplink information transmission path. FIG. 1 is a schematic flowchart of a method for determining an uplink information transmission path according to an embodiment of the present invention; as shown in FIG. 1 , the method includes:

Step 101: The terminal determines whether a trigger condition is satisfied.

Step 102: When it is determined that the trigger condition is met, switch the transmission path of the uplink transmission information from the first link corresponding to the first node to the second link corresponding to the second node, and pass the second link The uplink transmission information is sent to the second node such that the second node forwards the uplink transmission information to the first node.

In an optional embodiment of the present invention, judging by the terminal whether a trigger condition is satisfied includes: the terminal detects its own capability parameter, network quality parameter or transmission attribute parameter, and determines its own capability parameter, network quality parameter or transmission attribute parameter Whether the preset conditions are met.

In this embodiment, the terminal determines whether to change the transmission path of the uplink transmission information according to its own capability parameter, network quality parameter or transmission attribute parameter. The self-capability parameter represents whether the terminal is capable of transmitting uplink transmission information to the first node through the first link; the network quality parameter represents whether the network communication quality of the first node supports the transmission of uplink transmission information; the transmission attribute parameter indicates the current transmission situation through the first link, and the transmission attribute parameter may include, for example, the transmission duration, the number of transmission failures (or the number of retransmissions), and the like. The terminal may determine whether to change the transmission path of the uplink transmission information based on any one of the above information or a combination of any information. It can be understood that the terminal itself does not have the ability to transmit uplink transmission information to the first node through the first link, the network communication quality of the first node does not support the transmission of uplink transmission information, or the transmission currently transmitted through the first link. When the situation is not good, it is determined to change the transmission path of the uplink transmission information, that is, to switch the transmission path of the uplink transmission information from the first link corresponding to the first node to the second link corresponding to the second node, The uplink transmission information is sent to the second node over the second link.

In this embodiment, the first link may be a physical uplink shared channel (PUSCH, Physical Uplink Share Channel) or a physical uplink control channel (PUCCH, Physical Uplink Control Channel) corresponding to the first node; the second link It can be the PUSCH and/or PUCCH corresponding to the second node; it can be understood that when the terminal determines that the trigger condition is met, it switches the data mapped to the PUSCH or PUCCH of the first node to the PUCCH and/or PUSCH mapped to the second node transfer up.

In this embodiment, the first node and the second node may be an LTE base station and an NR base station, respectively, or an NR base station and an LTE base station, respectively, and may be both LTE base stations or both NR base stations.

The uplink transmission information is at least part of the information to be sent by the terminal to the first node, that is, all the information to be sent, or part of the information to be sent. As an implementation manner, the uplink transmission information is at least one of the following information: radio resource control (RRC, Radio Resource Control) signaling, random access signaling, medium access control layer control element (MAC CE, Media Access Control ControlElement), physical layer parameters; wherein, the physical layer parameters include at least one of the following: channel state information-reference signal (CSI-RS) resource indicator CRI (CSI-RS Resource Indicator), channel quality indicator (CQI) , ChannelQuality Indicator), Precoding Matrix Indicator (PMI, Precoding Matrix Indicator), Reference Signal Receiving Power (RSRP, Reference Signal Receiving Power), acknowledgment response/negative response (ACK/NACK) and so on.

As a first implementation manner, the judging whether the self-capability parameter, the network quality parameter or the transmission attribute parameter satisfies the preset threshold includes: the terminal judging whether the type of the uplink transmission information is the preset information type; the judging Satisfying the preset trigger condition includes: when the type of the uplink transmission information is the preset information type, determining that the trigger condition is met.

In this embodiment, the type of the uplink transmission information indicates a scenario or process corresponding to the current information transmission. As an example, the scenario or procedure is, for example, a random access procedure, and the uplink transmission information may be uplink information in the random access procedure. Then the terminal can pre-determine the preset information type, and when the type of the uplink transmission information is the preset information type, it is determined that the trigger condition is satisfied, and the transmission path of the uplink transmission information is changed from the first link corresponding to the first node. Switching to a second link corresponding to a second node over which the uplink transmission information is sent to the second node.

For example, after the UE is connected to the LTE base station, it needs to connect to the NR base station to form a dual connection. When initiating a random access (such as contention-based random access) process to the NR base station, the UE decides to use the second random access procedure. The uplink message is forwarded by the LTE base station. Therefore, when the uplink transmission information is transmitted, the uplink transmission information that should be mapped to the PUSCH channel corresponding to the NR base station is mapped to the PUSCH corresponding to the LTE base station, and marked. After receiving the uplink transmission information, it is forwarded to the NR base station to complete the subsequent random access process.

In other embodiments, for other uplink information after the random access is successful, the UE may determine whether to maintain the original transmission path or change the transmission path according to the following determination methods.

As a second implementation manner, the judging whether the self-capability parameter, the network quality parameter or the transmission attribute parameter meets a preset threshold includes: the terminal measuring the network quality parameter of the first node, and judging the first node's network quality parameter. Whether the network quality parameter is lower than the first preset threshold; the determining that the preset trigger condition is met includes: when the network quality parameter of the first node is lower than the first preset threshold, determining that the trigger condition is met.

In this embodiment, the network quality parameters include but are not limited to at least one of the following: RSRP, Reference Signal Receiving Quality (RSRQ, Reference Signal Receiving Quality), Received Signal Strength Indication (RSSI, Received Signal Strength Indication), signal and interference signal Noise ratio (SINR, Signal to Interferenceplus Noise Ratio) and so on. The terminal may pre-determine a first preset threshold, and when the network quality parameter of the first node is lower than the first preset threshold, it is determined that the trigger condition is met, and the transmission path of the uplink transmission information is changed to the one corresponding to the first node. The first link is switched to a second link corresponding to a second node over which the uplink transmission information is sent to the second node.

For example, the UE is in the EN-DC state, the LTE base station is the primary base station, and the NR base station is the secondary base station. When the UE wants to transmit uplink transmission information, assuming that the UE wants to send the uplink transmission information to the NR base station, the UE first performs RSRP measurement on the NR base station, and compares the measurement result with the RSRP threshold (ie, the first preset threshold). , when the measurement result is lower than the RSRP threshold (ie, the first preset threshold), it is decided to switch the transmission path of the uplink transmission information, that is, the uplink transmission information is sent to the LTE base station, and then the LTE base station forwards the uplink to the NR base station. way to transmit information.

As a third implementation manner, the judging whether the self-capability parameter, the network quality parameter or the transmission attribute parameter meets a preset threshold includes: the terminal detecting a failure to transmit the uplink transmission information through the first link The number of times or the number of retransmissions, to determine whether the number of failures or the number of retransmissions exceeds a second preset threshold; the determination to meet the preset trigger conditions includes: when the number of failures or the number of retransmissions exceeds the second preset threshold , determine that the trigger condition is met.

In this embodiment, the terminal may pre-determine a second preset threshold, and when the number of failures or the number of retransmissions in transmitting the uplink transmission information through the first link exceeds the second preset threshold, it is determined that a trigger condition is satisfied , switching the transmission path of the uplink transmission information from the first link corresponding to the first node to the second link corresponding to the second node, and sending the uplink transmission information through the second link to the second node. In practical applications, the terminal can set a counter; when the uplink transmission information fails to be sent once, or when the uplink transmission information is retransmitted once, the counter counts up by one until the count value of the counter reaches the second preset threshold. , determine that the trigger condition is met.

For example, the UE is in the EN-DC state, the LTE base station is the primary base station, and the NR base station is the secondary base station. The UE wants to send the uplink transmission information to the secondary base station. After the transmission fails, the UE counts the number of failures. When the UE fails N times (N=the second preset threshold), the UE decides to perform the transmission path of the uplink transmission information. Handover, that is, sending the uplink transmission information to the LTE base station, and then the LTE base station forwards the uplink transmission information to the NR base station.

As a fourth implementation manner, the judging whether the self-capability parameter, the network quality parameter or the transmission attribute parameter satisfies a preset threshold includes: the terminal detecting the transmission of the uplink transmission information through the first link duration, and judging whether the transmission duration exceeds a third preset threshold; the determining that a preset trigger condition is met includes: when the transmission duration exceeds a third preset threshold, determining that the trigger condition is met.

In this embodiment, the terminal may pre-determine a third preset threshold, and when the transmission duration of transmitting the uplink transmission information through the first link exceeds the third preset threshold, it is determined that a trigger condition is met, and the uplink transmission is determined to be satisfied. The transmission path of the transmission information is switched from the first link corresponding to the first node to the second link corresponding to the second node, and the uplink transmission information is sent to the second link through the second link node. In practical applications, the terminal may set a timer, and start the timer when it starts to transmit uplink transmission information through the first link for the first time, and the timing duration of the timer is the third preset threshold; if the timer times out , the transmission of the uplink transmission information through the first link is still unsuccessful, and it is determined that the trigger condition is satisfied.

For example, the UE is in the EN-DC state, the LTE base station is the primary base station, and the NR base station is the secondary base station. The UE needs to send the uplink transmission information to the secondary base station, and starts a timer, and the timing of the timer is the third preset threshold; if the timer expires, the UE decides to switch the transmission path of the uplink transmission information , that is, the uplink transmission information is sent to the LTE base station, and then the LTE base station forwards the uplink transmission information to the NR base station.

As a fifth implementation manner, the judging whether the self-capability parameter, the network quality parameter or the transmission attribute parameter satisfies the preset threshold includes: the terminal detects the PH parameter, and judges whether the PH parameter is lower than the fourth preset threshold; The determining that a preset trigger condition is met includes: when the PH parameter is lower than a fourth preset threshold, determining that the trigger condition is met.

In this embodiment, the terminal may pre-determine a fourth preset threshold, and when the terminal detects that its own PH parameter is lower than the fourth preset threshold, it determines that the trigger condition is met, and the transmission path of the uplink transmission information is set to the one corresponding to the first threshold. The first link of the node is switched to a second link corresponding to the second node over which the uplink transmission information is sent to the second node.

In an optional embodiment of the present invention, the method further includes: obtaining, by the terminal, the preset condition configured by the network device; or, the terminal determining the preset condition by means of a protocol agreement.

In this embodiment, as an implementation manner, at least one of the above-mentioned preset information type, first preset threshold, second preset threshold, third preset threshold, and fourth preset threshold may be stored by the network Configured by the device, for example, the network device notifies the terminal through broadcast information. As another implementation manner, at least one of the above-mentioned preset information type, first preset threshold, second preset threshold, third preset threshold, and fourth preset threshold may also be agreed by the terminal according to the protocol way to pre-write the terminal.

In an optional embodiment of the present invention, if the terminal determines the first preset condition in advance according to the manner agreed in the protocol, and then obtains the second preset condition configured by the network device, the update preset condition is the first preset condition. Two preset conditions, for example, the terminal determines the first preset threshold 1 by means of a protocol agreement, and obtains the first preset threshold 2 configured by the network device, then the terminal stores the first preset threshold 2, according to the first preset threshold 2. It is judged whether or not to switch the transmission path.

In other embodiments, the terminal obtains the preset conditions configured by the network device, and may also include information such as the effective duration of the preset conditions, and the terminal switches whether to switch according to the preset conditions configured by the network device and the corresponding effective duration. Judgment of the transmission path. For example, if the terminal determines the first preset threshold 1 by means of a protocol agreement, and obtains the first preset threshold 2 configured by the network device, and the valid duration of the first preset threshold 2 is t, the terminal stores the first preset threshold 2. Judging whether to switch the transmission path according to the first preset threshold 2, and start a timer, and the timing duration of the timer is set to t; Judgment to switch the transmission path; after the timer expires, the terminal determines whether to switch the transmission path according to the first preset threshold 1.

In an optional embodiment of the present invention, each time the terminal transmits uplink transmission information, it needs to judge whether to switch the transmission path, that is, execute the judgment of steps 101 to 102 . In other embodiments, the terminal may make only one judgment in a preset period based on a pre-agreed or the configuration of the network device, that is, the judgment in steps 101 to 102 is only performed once in the preset period; if it is determined that the path is switched, then During the preset period, the transmission path of the uplink transmission information will be switched from the first link corresponding to the first node to the second link corresponding to the second node; if it is determined that the path is not switched, the It is assumed that the uplink transmission information is still transmitted to the first node by the first link corresponding to the first node within the period.

In an optional embodiment of the present invention, in the process of sending the uplink transmission information to the second node through the second link, the uplink transmission information is still sent through the first link In other words, uplink diversity transmission is performed, and both primary and secondary links are used to transmit information. In practical applications, a Time Division Duplexing (TDD, Time Division Duplexing) mode can be used.
