Alternatively, the user device 110 may be a roadside device, for example, a street lamp, a signal lamp or other roadside device with a wireless communication function.
The base station 120 may be a network side device in a wireless communication system. The wireless communication system may be a fourth generation mobile communication (4G) system, which is also called a Long Term Evolution (LTE) system; alternatively, the wireless communication system may be a 5G system, which is also called a new air interface system or a 5G NR system. Alternatively, the wireless communication system may be a next-generation system of a 5G system. Among them, the Access Network in the 5G system may be referred to as a New Generation-Radio Access Network (NG-RAN).
The base station 120 may be an evolved node b (eNB) used in a 4G system. Alternatively, the base station 120 may be a base station (gNB) adopting a centralized distributed architecture in the 5G system. When the base station 120 adopts a centralized distributed architecture, it generally includes a Centralized Unit (CU) and at least two Distributed Units (DUs). A Packet Data Convergence Protocol (PDCP) layer, a Radio Link layer Control Protocol (RLC) layer, and a Media Access Control (MAC) layer are provided in the central unit; a Physical (PHY) layer protocol stack is disposed in the distribution unit, and the embodiment of the present disclosure does not limit the specific implementation manner of the base station 120.
The base station 120 and the user equipment 110 may establish a radio connection over a radio air interface. In various embodiments, the wireless air interface is based on a fourth generation mobile communication network technology (4G) standard; or the wireless air interface is based on a fifth generation mobile communication network technology (5G) standard, for example, the wireless air interface is a new air interface; alternatively, the wireless air interface may be a wireless air interface based on a 5G next generation mobile communication network technology standard.

The network Management device 130 may be a Core network device in a wireless communication system, for example, the network Management device 130 may be a Mobility Management Entity (MME) in an Evolved Packet Core (EPC).

The implementation form of the network management device 130 is not limited in the embodiment of the present disclosure.
In one embodiment, the remote UE and the relay UE may transmit data via the direct link, where the direct link connection fails, and the case includes one of:
a direct link failure; this failure of the direct link typically results in a failure due to the degradation of the quality of the direct link;
a configuration failure; the configuration failure may result in a failure due to an implementation error of the UE or the base station.
The configuration failure here is usually the configuration that the UE cannot be matched to the UE at the opposite end; for example, the remote UE cannot match the configuration of the relay UE.
In the above embodiment, if the direct link between the remote UE and the relay UE fails to be connected due to a configuration failure, the communication quality of the direct link is not changed, so that when the remote UE reselects the relay UE, the relay UE with the configuration failure is likely to be reselected again; thus, the probability that the direct link connection between the remote UE and the relay UE fails again is high.
In the embodiment of the disclosure, when the configuration failure occurs in the direct link between the remote UE and the relay UE, the relay UE may be reselected based on the reselection restriction condition, so that the probability of reselecting the relay UE before the configuration failure occurs is reduced, and the probability of the connection failure of the direct link is reduced.
As shown in fig. 2, an embodiment of the present disclosure provides a method for reselecting a relay UE, which is applied to a remote User Equipment (UE), and the method includes:
step S22: and reselecting the relay UE based on the reselection limiting condition in response to the failure of configuration of a direct link (SideLink, SL) between the remote UE and the relay UE.
The remote UE and the relay UE of the embodiment of the disclosure can be various types of user equipment; for example, the remote UE and the relay UE may be mobile phones, smart terminals, computers, servers, transceivers, tablets, or medical devices. As well as a game console, a multimedia device, or a wearable device, etc. It is only necessary that the remote UE and the relay UE can communicate through the SL connection.
In a wireless communication system, a relay UE here is a UE connected to a base station; here, the remote UE is a UE that is not connected to the base station, and the remote UE communicates with the base station through the relay UE.
The base station is an interface device for accessing the UE to the Internet; the base station may be various types of base stations, such as a 3G base station, a 4G base station, a 5G base station, or other evolved base station; the base station may also be a ground network base station or a base station of a non-ground network.
In some embodiments, the configuration failure is an access stratum (stratum) configuration failure. That is, the configuration failure is a configuration failure occurring at the AS layer.
In some embodiments, reselecting the relay UE based on a restricted reselection condition includes at least one of:
reselecting other UEs except the relay UE with failed configuration as the reselected relay UE based on the reselection limiting condition;
and based on the reselection limiting condition, reselecting the relay UE with the lowest priority and failed in configuration as the reselected relay UE.
Here, the relay UE with the lowest priority and failed in reselection configuration is taken as the reselected relay UE, that is, the relay UE with the lowest priority and failed in reselection is taken as the reselected relay UE except for the relay UE with the lowest priority and failed in configuration.
In some embodiments, reselection conditions are restricted, including but not limited to one of:
not selecting the relay UE which fails in configuration;
not selecting the relay UE with the same serving cell as the relay UE before reselection;
preferentially selecting relay UE different from the relay UE before reselection;
and preferentially selecting the relay UE with the service cell different from the service cell of the relay UE before reselection.
Here, the remote UE may acquire the relay UE that has failed in configuration; here, the relay UE in which the reconfiguration failure occurs includes at least one of: the UE with failed configuration before reselection, any relay UE with failed configuration and the relay UE with failed configuration within the preset time length.
Here, the remote UE may obtain a serving cell corresponding to each relay UE.
In other embodiments, the reselection limiting condition may be: and not selecting the relay UE with the same serving cell as the relay UE serving cell with the failure configuration.
The serving cell of the relay UE here may be one or more.
Of course, in other embodiments, the reselection limiting condition may also be: the relay UE with the same number of serving cells as the serving cells of the relay UE before reselection exceeding a preset value is not selected; or, the relay UEs whose serving cells are the same as the serving cell of the relay UE in which the configuration failure occurs and whose number exceeds the predetermined value are not selected.
For example, in some application scenarios, the serving cell of the relay UE1 includes cell 1, cell 2, and cell 3, and the relay UE1 is a relay UE before reselection; the server cell of the relay UE2 includes cell 1 and cell 3 and cell 4; serving cells of the relay UE3 include cell 1, cell 2, and cell 5; the preset value is 1; thus, the remote UE does not select the relay UE3 as the reselected relay UE.
Of course, in other embodiments, the reselection limiting condition may also be another reselection condition, and only the condition that the relay UE is not the relay UE before the preferential selection reselection needs to be satisfied. For example, the reselection limiting conditions may include: and not selecting the relay UE which fails in configuration before reselection. As another example, limiting reselection conditions includes: and if the relay UE except the reselected relay UE is not reselected to the relay UE, selecting the relay UE before reselection as the reselected relay UE, and the like.
In the embodiment of the present disclosure, the remote end may reselect the relay UE according to the reselection limiting condition, and compared with reselecting the relay UE without any manner (for example, without using the reselection limiting condition), the probability of reselecting the relay UE that fails in the configuration before reselection can be greatly reduced, so that the probability of the occurrence of the connection failure of the direct link again is greatly reduced, that is, the success rate of the connection between the remote end UE and the reselected relay UE on the direct link is improved.
In the embodiment of the present disclosure, the reselection restriction condition may be that relay UE that has failed to be configured is not selected, and/or relay UE whose serving cell is the same as the serving cell of the relay UE before reselection is not selected; therefore, the relay UE which fails in configuration can be greatly reduced, and the connection success rate of the direct link between the remote UE and the reselected relay UE is improved.
In the disclosed embodiment, the reselection limiting condition may be that a relay UE other than the pre-reselection relay UE is preferentially selected, and/or a relay UE whose serving cell is preferentially selected to be different from the serving cell of the pre-reselection relay UE; therefore, the probability of selecting the relay UE which is not failed to be configured can be increased, the probability that the connection of the direct link of the reselected UE fails again can be greatly reduced, and the connection success rate of the direct link of the remote UE and the reselected relay UE is improved.
As shown in fig. 3, in some embodiments, a reselection method of a relay UE includes:
step S21: a restricted reselection condition for use in performing reselection is determined.
One implementation of S21 herein is:
determining a reselection limiting condition used for reselection based on the predetermined specification;
and acquiring the reselection limiting condition broadcasted by the relay UE before reselection.
The pre-specification herein may be a specification in a communication standard protocol; for example, the reselection restriction condition at the remote UE is stored in advance.
In the embodiment of the present disclosure, the remote UE may determine, according to the communication standard protocol, a reselection restriction condition used for reselection; in this way, each remote UE can reselect the relay UE according to the uniform reselection restriction condition, thereby achieving a uniform communication standard.
In the embodiment of the present disclosure, the remote UE may also obtain the reselection limiting condition according to the relay UE before reselection, and provide multiple manners of selecting the reselection limiting condition that needs to be used and perform reselection based on the latest reselection limiting condition.
In some embodiments, a manner of implementing step S21 described above includes:
and determining a reselection limiting condition used for reselection according to the configuration source of the relay UE before reselection.
The source of configuration of the relay UE here may be from the base station or the relay UE.
The configuration source may be an AS configuration source.
In some embodiments, the method further comprises:
and responding to the configuration of the relay UE before reselection from the base station, and determining that the reselection limiting condition used for reselection is not to select the relay UE with the same serving cell as that of the relay UE before reselection or preferentially select the relay UE with the different serving cell from that of the relay UE before reselection.
In the embodiment of the present disclosure, if the configuration of the relay UE before reselection is from the base station, the remote UE can easily obtain the serving cell corresponding to each relay UE. The far-end UE may determine: not selecting the relay UE with the same serving cell as the relay UE before reselection or preferentially selecting the relay UE with the different serving cell as the reselection limiting condition used by reselection; so that a more appropriate restricted reselection condition can be selected.
In other embodiments, the method further comprises:
and responding to the configuration of the relay UE before reselection from the relay UE, and determining that the reselection limiting condition used for reselection is not to select the relay UE with failed configuration or preferentially select the relay UE different from the relay UE before reselection.
In the embodiment of the present disclosure, if the configuration of the relay UE before reselection is from the relay UE, the remote UE may more easily obtain whether the configuration of each relay UE fails. In this way, the remote UE may directly determine that the relay UE with failed configuration is not selected or that the relay UEs except for the UE before reselection are preferentially selected as a more appropriate reselection limiting condition.
Thus, in the embodiment of the present disclosure, the reselection restriction condition corresponding to the configuration source may be determined according to the configuration source of each relay UE; that is, the embodiment of the present disclosure may select a more appropriate reselection limiting condition, so that the relay UE reselected based on the more appropriate reselection limiting condition may further reduce the probability of a connection failure with the direct link of the remote UE.
As shown in fig. 4, in some embodiments, the method further comprises:
step S20: and acquiring a configuration source of the relay UE before reselection.
In some embodiments, a manner of implementing step S20 described above includes:
and determining a configuration source of the relay UE before reselection based on the broadcast message of the base station forwarded by the relay UE before reselection.
The broadcast message here may be a system message block; for example, the broadcast message is SIB 13. Of course, in other embodiments, the broadcast message may be other broadcast messages; for example, any suitable system message from SIB1 to SIB18 may be used.
In the embodiment, the configuration source of the relay UE before reselection may be obtained by forwarding a broadcast message of the base station; in its embodiment, the configuration source for acquiring the relay UE may also be obtained based on other entities on the network side; for example, the UE is acquired by any other relay UE connected to the relay UE; the other relay UE includes its own source of configuration. For another example, the remote UE may also obtain the configuration source of the relay UE1 based on the relay UE1 if the remote UE needs to obtain the configuration source.
In some embodiments, determining the configuration source of the pre-reselection relay UE based on the relay UE forwarding the broadcast message of the base station before reselection includes:
responding to a broadcast block carrying a direct link in a broadcast message, and determining a configuration source base station of the relay UE before reselection;
alternatively, the first and second electrodes may be,
and determining the configuration source UE of the relay UE before reselection in response to the broadcast block which does not carry the direct link in the broadcast message.
The broadcast block of the direct link here includes, but is not limited to, the configuration source of the relay UE.
In the embodiment of the present disclosure, if the broadcast message carries a broadcast block of the direct link, the broadcast block is a broadcast message forwarded from the base station; in this way, it can be determined that the configuration source of the relay UE before reselection is the base station. If the broadcast message does not carry the broadcast block of the direct link, it can be determined that the base station does not have the broadcast block of the direct link, and the broadcast block of the direct link is more likely to come from the relay UE; and determining that the configuration source of the relay UE before reselection is the relay UE. Therefore, according to the embodiment of the disclosure, the configuration source of the relay UE can be determined more accurately according to whether the broadcast message carries the broadcast block of the direct link.
In other embodiments, a method for implementing step S21 includes:
in response to a failure of reselection of the relay UE when the relay UE different from the relay UE before reselection is selected based on the priority, selecting the relay UE before reselection as the reselected relay UE;
alternatively, the first and second electrodes may be,
and in response to the reselection failure of the relay UE based on the relay UE with the service cell different from the service cell of the relay UE before reselection, selecting the relay UE before reselection as the reselected relay UE.
In the embodiment of the present disclosure, if the relay UE different from the relay UE before reselection is not reselected to the relay UE based on the priority selection, that is, when the relay UE connected to the direct link of the remote UE is not reselected, the relay UE before reselection may be reselected as the reselected relay UE. Therefore, the relay UE can be reselected based on more relay UEs, and the probability of reselecting the relay UE is increased.
In the embodiment of the present disclosure, if a UE that is different from a serving cell of a relay UE before reselection is not reselected to the relay UE based on a preference serving cell, that is, if a relay UE connected to a direct link of a remote UE is not selected, the relay UE before reselection may be reselected to be selected as the reselected relay UE. Therefore, the relay UE can be reselected based on more relay UEs, and the probability of reselecting the relay UE is increased.
Of course, in other embodiments, the implementation manner of step S21 may also be: and in response to that the relay UE which is different from the serving cell of the relay UE before reselection is reselected to the relay UE based on the priority selection serving cell, reselecting the relay UE based on the relay UE of which the number of the serving cells is different from that of the relay UE before reselection exceeds a preset value.
In the above example, the step S21 may further include:
and in response to the failure of the reselection of the relay UE when the number of different serving cells in the serving cell based on the serving cell and the relay UE before reselection exceeds a predetermined value, reselecting the relay UE based on the relay UE of which the number of different serving cells in the serving cell based on the serving cell and the relay UE before reselection is less than or equal to the predetermined value.
In the above example, the step S21 may further include:
and in response to that the relay UE of which the number of different serving cells is less than or equal to a preset value in the serving cell based on the serving cell and the serving cell of the relay UE before reselection is not reselected to the relay UE, selecting the relay UE before reselection as the reselected relay UE.
Thus, in the embodiment of the present disclosure, if the relay UE whose number of serving cells exceeds the predetermined value is based on the preferred serving cell and the relay UE before reselection is reselected to the relay UE, the relay UE may be selected hierarchically; for example, reselected relay UEs may be selected from relay UEs whose number of serving cells is different from that of the relay UEs before reselection and exceeds a predetermined value; and if the relay UE is not reselected based on the condition, reselecting the relay UE from the relay UE of which the different numbers of the serving cells and the serving cell of the relay UE before reselection are less than or equal to the preset relay UE. Therefore, the relay UE can be reselected from the relay UE which fails in configuration as far as possible on the premise that the reselected relay UE can be selected based on more relay UEs, and therefore the success rate of connection of the reselected relay UE and a direct link of the remote UE can be further improved.
As shown in fig. 5, in some embodiments, the step S22 may include:
step S221: and responding to the SL configuration failure between the remote UE and the relay UE, starting a timer, and reselecting the relay UE based on the reselection limiting condition within the timing time range of the timer.
Here, the remote UE sets a timer and obtains a timing period of the timer. Here, the timing period of the timer is within the timing time range of the timer.
Here, the timing period of the timer is pre-configured for the remote UE or determined based on the configuration of the relay UE to the remote UE.
In some embodiments, a reselection method of a relay UE includes: the remote UE pre-configures the timing period of the timer. For example, if the timing period of the timer configured by the remote UE is 1 minute, the relay UE may be reselected based on the reselection restriction condition within 1 minute of the timer running after the timer is started.
In other embodiments, a method for reselection of a relay UE includes: acquiring configuration information from the relay UE to the remote UE, wherein the configuration information carries a timing period of a timer.
The configuration information here may be that the relay UE sends to the remote UE before the direct link between the relay UE and the remote UE is disconnected; alternatively, the configuration information here may also be sent by the relay UE to another network-side entity, such as a base station, which is broadcasted by the base station to the remote UE.
The timing time of the timer here may also be a communication protocol specification.
As such, in the disclosed embodiments, the timing period of the timer may be determined in a variety of ways.
In the embodiment of the present disclosure, the remote UE may reselect the relay UE based on the reselection restriction condition within the timing time range of the timer; in this way, the time for reselecting the relay UE can be shortened, and the efficiency for reselecting the relay UE can be improved.
One specific example is provided below in connection with any of the embodiments described above:
as shown in fig. 6, an embodiment of the present disclosure further provides a method for reselecting a relay UE, which is applied to a remote UE, and includes the following steps:
step S31: establishing an SL connection with a first relay UE;
in an alternative embodiment, the remote UE establishes a SL connection with the first relay UE.
Step S32: determining that AS configuration failure occurs in a SL connection with a first relay UE;
in an optional embodiment, the remote UE determines that an AS configuration failure occurs in the SL connection between the remote UE and the first relay UE.
Step S33: receiving a system message broadcasted by the first relay UE, wherein the system message at least comprises a reselection limiting condition;
in an optional embodiment, the remote UE receives a system message broadcast by the first relay UE, where the system message includes at least a reselection restriction condition; reselection limiting conditions comprising: preferentially selecting a relay UE whose serving cell is different from a serving cell of the first relay UE.
Of course, in other alternative embodiments, the remote UE may also obtain the reselection restriction condition according to other manners; for example, the reselection limiting condition may be obtained according to the above embodiment based on an AS configuration source and the like.
Of course, in other alternative embodiments, the reselection limiting condition may also be any reselection limiting condition in the above embodiments.
Step S34: the remote UE reselects the second relay UE as the relay UE of the remote UE based on the reselection limiting condition;
in an optional embodiment, the remote UE preferentially selects a second relay UE serving less than a serving cell of the first relay UE as the reselected relay UE.
The serving cell where the remote UE acquires the first relay UE is cell 1, and the serving cells where the second relay UE, the third relay UE, the fourth relay UE, and the fifth relay UE are measured are cell 1, cell 2, cell 1, and cell 2, respectively. The remote UE determines that the second relay UE and the fifth relay UE can be selected as reselected relay UE based on the fact that the serving cells of the second relay UE and the fifth relay UE are different from the serving cell of the first relay UE before reselection. In this example, the remote UE selects the second relay UE as the reselected relay UE; of course, in other examples, the remote UE may also select the fifth relay UE as the reselected relay UE.
In the embodiment of the present disclosure, when the configuration of the direct link between the remote UE and the first relay UE fails, the relay UE may be reselected based on the reselection restriction condition. Therefore, compared with the method for reselecting the relay UE in any mode (for example, according to no reselection limiting condition), the probability of reselecting the relay UE which fails in configuration before reselection can be greatly reduced, so that the probability of the connection failure of the direct link again is greatly reduced, and the connection success rate of the direct link between the remote UE and the reselected relay UE is improved.
Furthermore, the reselection limiting condition is to select a relay UE of a serving cell different from the serving cell of the first relay UE, so that the connection success rate of the direct link between the cloud UE and the reselected relay UE can be further improved.
