< first embodiment >
As previously described, VMR is capable of providing relay services to users located outside the vehicle. For example, when the VMR reaches the VMR service point, a User Equipment (UE) located at the VMR service point may be served. VMR service points are places in life where communication services can be provided by VMR, such as bus stops, gas stations, parking lots, etc.
The coverage of the VMR service point is an area where the VMR can provide communication services, in other words, in the area, the UE can provide communication services by the VMR. The coverage of the VMR service point depends on factors such as the transmit power of the VMR.
By relaying communication with VMR, the UE can improve communication quality (especially in case of lower communication quality provided by a base station such as the gNB) on the one hand, and can reduce power consumption of the UE on the other hand, because of the relatively close distance of the UE from the VMR. Because frequent handovers may be caused due to the mobility of the VMR, the present embodiment provides an electronic device 100 for guaranteeing service continuity of the UE in the vehicular relay scenario.
As shown in fig. 1, an electronic device 100 for wireless communication according to the present embodiment includes: a determining unit 101 configured to determine a service continuity guarantee policy for UEs located within a coverage area of the VMR service point based on at least one of state information of the VMR and state information of the buffer in response to at least one of a plurality of trigger events; and an implementation unit 102 configured to implement the service continuity guarantee policy.
The determination unit 101 and the implementation unit 102 may be implemented by one or more processing circuits, which may be implemented as a chip, a processor, for example. Also, it should be understood that each functional unit in the electronic device shown in fig. 1 is merely a logic module divided according to the specific functions it implements, and is not intended to limit the specific implementation.
The electronic device 100 may be provided on the base station side or may be communicatively connected to the base station, for example. The base station in the present application may also be a transceiver Point (Transmit Receive Point, TRP) or an Access Point (AP). Here, it should also be noted that the electronic device 100 may be implemented at a chip level or may also be implemented at a device level. For example, the electronic device 100 may operate as a base station itself, and may also include external devices such as memory, transceivers (not shown), and so forth. The memory may be used to store programs and related data information that the base station needs to perform to implement various functions. The transceiver may include one or more communication interfaces to support communication with different devices (e.g., UE, VMR, other base stations, etc.), the implementation of the transceiver is not particularly limited herein.
Moreover, the first, second, etc. herein are for distinguishing purposes only and not to be construed as a limitation on any order, etc.
For example, the plurality of trigger events may include one or more of the following: the new UE enters the coverage of the VMR service point (hereinafter also referred to as a first trigger event); the VMR that is providing service is to leave the VMR service point (hereinafter also referred to as a second trigger event); in the case where a UE located in the coverage of the VMR service point is not served by the VMR, the VMR that can provide the service reaches the VMR service point (hereinafter also referred to as a third trigger event); and the buffer can no longer provide service (hereinafter also referred to as a fourth trigger event). It should be understood that only some examples of trigger events are given herein, but that other trigger events may be defined as well, which is not limiting.
Upon occurrence of one or more trigger events, the determining unit 101 determines a service continuity guarantee policy for one or more UEs within a coverage area of the VMR service point based on at least one of the state information of the VMR and the state information of the buffer.
The state information of the VMR may be provided by the VMR, and the state information of the buffer may be provided by the buffer. Accordingly, as shown in fig. 2, the electronic device 100 may further include a communication unit 103 configured to obtain a report of the state information of the VMR from the VMR and a report of the state information of the buffer from the buffer.
For example, the communication unit 103 may acquire the report of the state information of the VMR and/or the report of the state information of the buffer in at least one of the following ways: periodically acquiring; acquired in response to the occurrence of a trigger event. Specifically, the communication unit 103 may acquire the above report at a predetermined period, and use the latest acquired report when a trigger event occurs; the report can also be obtained when a trigger event occurs so as to ensure timeliness of the report; a combination of these two approaches may also be employed. Furthermore, the communication unit 103 may also acquire the report of the state information of the VMR and the report of the state information of the buffer in mutually different manners, which are not limitative.
The state information of the VMR is used to indicate the current state of the VMR, such as the time at which the service can be provided at the current VMR service point, etc. Illustratively, the state information of the VMR may include one or more of the following: residual residence time of VMR at VMR service point, residual arrival time and residual residence time after arrival of VMR relative to VMR service point, position information of VMR, speed information of VMR, direction information of VMR. This is not limiting and the state information of the VMR may also include other parameters such as the number of boarding and disembarking vehicles at the VMR service point, and the like. For a VMR, after its remaining residence time at the VMR service point, the VMR can no longer serve the UE at the VMR service point. The remaining arrival time of a VMR relative to a VMR service point is the time from when the VMR can serve the UE of the VMR service point. The position information of the VMR, the speed information of the VMR, the direction information of the VMR, the number of vehicles getting on or off at the VMR service point, and the like can be used to estimate the remaining stay time or the remaining arrival time of the VMR.
The buffer may be used to buffer data files, for example, to provide services to the UE when communication quality is poor or no connection is available. The buffer is mainly used in non-real-time service communication scenes, such as scenes of watching movies, listening to music, browsing web pages, and the like. The buffers may include buffers of the device (e.g., UE) itself and/or edge buffers. The edge buffer is located, for example, on an edge node of the network. This is not restrictive, and any buffer which has data transmission capability and is capable of establishing a connection with the UE may be used as the buffer in this embodiment. Such a buffer may be provided in a Road Side Unit (RSU), for example.
The status information of the buffer may include one or more of the following: buffer size, buffer read rate, service time of the buffer. For example, in the case of a buffer size B, if the buffer read rate (e.g., the rate at which the user reads or plays the file) is r, the service time of the buffer is B/r.
The following will describe service continuity guarantee policies when different trigger events occur in a real-time service communication scenario and a non-real-time service communication scenario, respectively. It should be understood that these strategies are merely exemplary and not limiting.
Real-time service communication scenario
In a real-time service communication scenario, the determining unit 101 is configured to determine a service continuity guarantee policy for the UE based on a longest remaining residence time of the VMR capable of providing the service at the VMR service point in response to at least one of a plurality of trigger events.
For example, the determination unit 101 may be configured to: in the case where the longest remaining residence time is above the predetermined time threshold, determining a service continuity guarantee policy as a VMR corresponding to the longest remaining residence time will serve the UE, the implementing unit 102 indicating to establish a link between the VMR and the UE; and determining a service continuity guarantee policy as the base station will serve the UE if the longest remaining residence time is not above a predetermined time threshold, the implementing unit 102 establishing or maintaining a link between the base station and the UE. The different trigger events will be described below.
In case of a first trigger event, i.e. the new UE entering the coverage of the VMR service point, the determination unit 101 is based on the information of the VMR service pointResidual residence time t of each VMR i that can provide service i To screen out the VMR with the longest remaining residence time (denoted as VMR i * ) And judge VMR i * Is not longer than the remaining residence time of (2) Whether or not to be at a predetermined time threshold T 1 Above, if the determination is yes, then VMR i is determined * To serve the new UE, implementation unit 102 instructs vmri to be established * A link with a new UE; otherwise, it is determined that the base station (gNB) is to serve the new UE, and the implementing unit 102 establishes a link between the gNB and the new UE.
For ease of understanding, fig. 3 shows an example of a related information flow. As shown, when a new UE enters the coverage of the VMR service point and sends a connection request to the gNB, each VMR within the VMR service point estimates its own remaining residence time and reports the remaining residence time to the gNB. Illustratively, the base station may instruct the VMR to report or the VMR may report autonomously. For example, the VMR may estimate the remaining stay time from its own position information, velocity information, and the like. Furthermore, as previously mentioned, the VMR may also report its status information periodically, neither of which is limiting. gNB makes a decision as described above, i.e. selects the remaining residence time that is longest and at a predetermined time threshold T 1 VMR i above * Indicating new UE and VMR i * Is connected with VMRi * A link connection is established to inform that there is a new UE access. Then VMR i * Establishment of link connection with new UE, VMR i * And informing the gNB that the connection establishment is completed. Then VMR i * Data transmission is performed as a relay between the gNB and the new UE.
Fig. 4 shows another example of a related information flow. In this example, VMR 1 through VMR n are schematically shown to represent the individual VMRs at the VMR service point. The process before decision making is the same as the corresponding part in fig. 3 and is not repeated here. gNB finds in the decision that there is no remaining residence time at the predetermined time threshold T 1 The above VMR, in which case the gNB determines that the new UE is to be served directly by the gNB, thereby establishing a link connection with the new UE and proceedingAnd (5) data transmission.
In the case of the second trigger event, that is, the VMR m that is providing the service is to leave the current VMR service point, the determining unit 101 needs to determine a service continuity guarantee policy for a UE (hereinafter referred to as a target UE for convenience of description) that is being served by the VMR m that is to leave the VMR service point. Specifically, the determination unit 101 is based on the remaining stay time t of each VMR i that can provide services at the VMR service point i To screen out the VMR with the longest remaining residence time (denoted as VMR i * Generally, i * Different from m), and determines VMR i * Is not longer than the remaining residence time of (2)Whether or not to be at a predetermined time threshold T 1 Above, if the determination is yes, then VMR i is determined * To serve the target UE, implementation unit 102 instructs to establish vmri * A link with a target UE; otherwise, it is determined that the base station (gNB) is to serve the target UE, and the implementing unit 102 establishes a link between the base station (gNB) and the target UE.
Fig. 5 shows an example of a related information flow. As shown in fig. 5, the target UE and the gNB perform data transmission using VMR m as a relay. For some reason, VMR m will leave the current VMR service point. Each VMR at the VMR service point estimates its own remaining residence time and reports the remaining residence time to the gNB. Illustratively, the base station may instruct the VMR to report or the VMR may report in response to the occurrence of the second trigger event. Similarly, the VMR may estimate the remaining stay time from its own position information, velocity information, and the like. Furthermore, as previously mentioned, the VMR may also report its status information periodically, neither of which is limiting. Note that for simplicity, only VMR i is shown in the figure * As examples of other VMRs. gNB makes a decision as described above, i.e. selects the remaining residence time that is longest and at a predetermined time threshold T 1 VMR i above * Indicating target UE and VMR i * Connection, i.e. target UE is to be handed over to vmri * Specifically, the gNB informs the VMR m and the target UE of the handover information. And gNB and VMR i * Establishing a link connection to inform it of handover information. Then VMR i * Establishment of link connection with target UE, VMR i * And informing the gNB that the connection establishment is completed. Then VMR i * Data transmission is performed as a relay between the gNB and the target UE. A data transmission link between the target UE and the gNB using VMR m as a relay is released.
Fig. 6 shows another example of a related information flow. In this example, the process prior to decision making is the same as the corresponding part in fig. 5 and is not repeated here. gNB finds in the decision that there is no remaining residence time at the predetermined time threshold T 1 The VMR above, in which case the gNB determines that the target UE will switch to the gNB to continue communication, informs the VMR m and the target UE of the switching information, and then establishes a link connection with the target UE and performs data transmission.
In the case of a third trigger event, that is, when a UE located in the coverage area of the VMR service point is not served by the VMR, when the VMR that can provide the service reaches the VMR service point, the determining unit 101 needs to determine a service continuity guarantee policy for the UE not served by the VMR (hereinafter referred to as a target UE for convenience of description). Specifically, the determination unit 101 determines whether the remaining stay time T of the newly arrived VMR (hereinafter referred to as new VMR) is at a predetermined time threshold T 1 Above, if the determination is yes, it is determined that the new VMR will serve the target UE, and the implementation unit 102 instructs to establish a link between the new VMR and the target UE; otherwise, it is determined that the base station (gNB) will continue to serve the target UE, and the implementing unit 102 maintains a link between the base station (gNB) and the target UE.
Fig. 7 shows an example of a related information flow. As shown in fig. 7, the target UE is being served by the gNB, and the new VMR arrives at the VMR service point so that relay service can be provided for the target UE. The new VMR estimates its own remaining residence time t and reports to the gNB. Illustratively, the base station may indicate that the new VMR is reported or that the VMR may report in response to the occurrence of a third trigger event. gNB performs the decision as described above, determining that the remaining residence time T of the new VMR is at the predetermined time threshold T 1 The above thereby determines that the target UE is to switch to the new VMR. Specifically, the gNB informs the target UE of the handover information, i.e., informs the target UE that it will handover to the new VMR. And gNB and new VMR constructionThe link connection is established to inform it of handover information. Then, the new VMR completes the establishment of the link connection with the target UE, and informs the gNB that the connection establishment is completed. In this way, a data transmission link via the new VMR as a relay is established between the target UE and the gNB for data transmission. Then, the direct data link between the target UE and the gNB is released. On the other hand, if the gNB determines in decision that the remaining residence time T of the new VMR is not at the predetermined time threshold T 1 Above, the link between the gNB and the target UE is maintained without performing any handover operation.
Non-real-time service communication scenario
Note that various service continuity guarantee policies under the real-time service communication scenario described above may also be applicable to non-real-time service communication scenarios. In addition, in the non-real-time service communication scene, the stability and the continuity of the user service can be further improved by utilizing the buffer. Therefore, the service continuity guarantee policy will be explained below for the case of using the buffer.
For example, in a non-real-time service communication scenario, the determining unit 101 may determine the service continuity guarantee policy for the new UE based on the longest remaining residence time of the VMR capable of providing service at the VMR service point in response to the first trigger event, i.e., the new UE entering the coverage of the VMR service point.
In the case of this first trigger event, since the use of the buffer is not involved, the operation of the determination unit 101 and the implementation unit 102 is the same as that in the real-time service communication scenario. That is, the determining unit 101 is configured to determine the service continuity guarantee policy that the VMR corresponding to the longest remaining residence time will serve the new UE, in the case where the longest remaining residence time is above the predetermined time threshold, the implementing unit 102 instructs to establish a link between the VMR and the new UE; and determining a service continuity guarantee policy as a base station (gNB) to serve the new UE if the longest remaining residence time is not above a predetermined time threshold, the enforcing unit 102 establishing a link between the base station and the new UE. Examples of specific information flows are shown in fig. 3 and 4, and specific descriptions are referred to above and are not repeated here.
Further, the determination unit 101 may determine a service continuity guarantee policy for a UE (hereinafter also referred to as target UE) being served by the VMR to be left, based on the remaining stay time of VMRs capable of providing services among the remaining VMRs at the VMR service point, the remaining arrival time of VMRs to reach the VMR service point, and the remaining stay time after arrival, and the service time of the buffer, in response to the second trigger event, that is, the VMR m being served is to leave the current VMR service point.
It can be seen that in the case of the second trigger event, the gNB considers the state information of the VMR and the state information of the buffer immediately before reaching the VMR service point in addition to the state information of the VMR at the VMR service point when making a decision, compared to in the real-time service communication scenario. This is because, in the case where no VMR can provide relay service, the buffer may temporarily provide service so that the UE may not need to directly connect to the gNB.
For ease of understanding, fig. 8 shows a schematic diagram of the flow of the operation of the determination unit 101, i.e. a schematic diagram of the decision process of the gNB. It should be understood that this decision process is exemplary only, and not limiting.
When the second trigger event occurs, each VMR at the VMR service point estimates its own remaining residence time and reports the remaining residence time to the gNB, i.e., the VMR that arrives at the VMR service point estimates its own remaining arrival time and remaining residence time after arrival and reports the remaining arrival time and remaining residence time to the gNB, and the buffer reports the buffer size and buffer read rate to the gNB or reports the service time of the buffer, as shown in the relevant information flow in fig. 9 (wherein VMR i is shown * As an example of other VMRs at VMR service points). Note that although the buffer is shown separately from the target UE in fig. 9, if the buffer is the buffer of the target UE itself, the information reporting process of the buffer is actually performed by the target UE. Illustratively, the base station may instruct the VMR and the cache to report or the VMR and the cache may report in response to the occurrence of the second trigger event.
The VMR may estimate the remaining residence time and/or the remaining arrival time according to its own location information, speed information, etc., and the VMR that is about to arrive at the VMR service point may be, for example, a VMR that will arrive at the VMR service point within a predetermined time, which may be configured or preconfigured by the base station. The service time of the buffer may be the quotient of the buffer size divided by the buffer read rate. Furthermore, as previously mentioned, the VMR and/or the buffer may also periodically report its status information, neither of which is limiting.
As shown in fig. 8, first, the determination unit 101 determines whether the longest remaining stay time of the VMR capable of providing the service at the VMR service point is at a predetermined time threshold T 1 The above. If so, the determination unit 101 determines the service continuity guarantee policy as the VMR corresponding to the longest remaining stay time (e.g., denoted as VMR i * The residual residence time is) Will serve the target UE. Implementation unit 102 will instruct the establishment of the VMR i * The link with the target UE and the link between VMR m to leave and the target UE is released. Fig. 9 shows an example of the relevant information flow of this case. It can be seen that the information flow in fig. 9 after the decision of the gNB is similar to fig. 5, and the detailed description is referred to above and will not be repeated here.
If the longest remaining residence time of VMR capable of providing service at the VMR service point is not at the predetermined time threshold T 1 Above, i.e., the target UE cannot switch to other VMRs of the VMR service point, the determining unit 101 needs to further determine whether the VMR to be reached can cooperate with the buffer to provide continuous services. For example, if the buffer is able to provide a service within a time when the VMR that is about to arrive has not arrived, the determination unit 101 determines that the VMR that is about to arrive and the buffer are able to cooperate to provide a continuous service, and determines the service continuity guarantee policy as being provided by the buffer after the VMR m leaves. Then, after the service time of the buffer has elapsed, the corresponding VMR has reached the VMR service point, so that the service can continue to be provided to the target UE.
Specifically, as shown in FIG. 8, provision can be made at the VMR service pointThe longest remaining residence time of the VMR of the service is not at the predetermined time threshold T 1 In the above case, the determination unit 101 determines the VMR (denoted as VMR j) whose remaining arrival time is the shortest * ) Whether the remaining residence time after arrival of (a) is at a predetermined time threshold T 1 The above. If the determination is no, the determination unit 101 determines the service continuity guarantee policy as that the base station (gNB) will serve the target UE. The enforcement unit 102 will establish a link between the gNB and the target UE and release the link between the VMR m to leave and the target UE. Fig. 10 shows an example of the relevant information flow of this case. It can be seen that the information flow in fig. 10 after the decision of the gNB is similar to fig. 6, and the detailed description is referred to above and will not be repeated here.
On the contrary, if the determination unit 101 determines VMR j * Is at a predetermined time threshold T 1 Above, the VMRj is judged * The remaining arrival time (noted as) Whether or not it is less than or equal to the service time t of the buffer b (t b =b/r). If->I.e. VMR j after the service time of the buffer has been exhausted * If the UE has not arrived, the determining unit 101 determines whether the target UE can be served by a base station (gNB). The determining unit 101 determines the service continuity guarantee policy as the base station (gNB) will serve the target UE if the target UE can be served by the base station. The enforcement unit 102 will establish a link between the gNB and the target UE and release the link between the VMR m to leave and the target UE. The relevant information flow can still be seen with reference to fig. 10. If the target UE cannot be served by the base station, the determination unit 101 determines VMR j * Residual arrival time->Whether or not it is greater than or equal to the service time t of the buffer b Vmri capable of providing longest remaining residence time with VMR service point * Is +.>The sum, i.e. determine that the service time in the buffer is exhausted and VMR i * VMR j after serving the longest remaining residence time * Whether or not it is reachable. If->Description of the run out in service time of the buffer and VMR i * VMR j after serving the longest remaining residence time * Is still unreachable, at which time the determination unit 101 determines the service continuity guarantee policy as vmri * The target UE will be served. Implementation unit 102 will instruct the establishment of the VMR i * The relevant information flow can still refer to fig. 9 for the link with the target UE and for releasing the link between VMR m to leave and the target UE. Subsequently, when VMR i * Upon leaving, the second trigger event is triggered again and the decision flow of fig. 8 is performed by the determination unit 101. And if->Description in buffer and VMRi * In the case of successively providing services, the VMR j can wait * Reaching to thereby provide continuous service, at which time the determination unit 101 determines the service continuity guarantee policy as vmri * Serving target UE and in vmri * The buffer continues to provide service after leaving. The related information flow can be referred to fig. 11A and 11B, and the difference between fig. 11A and 11B and fig. 9 is that in VMR i * After leaving, the target UE automatically switches to the buffer for data transmission and releases VMR i * As a relay link. Fig. 11A shows a case where the buffer is a self buffer, and fig. 11B shows a case where the buffer is an edge buffer. It can be seen that in case the buffer is an edge buffer, the gNB also informs the edge buffer of the handover information, in VMR i * After leaving, a link connection is established between the target UE and the edge buffer for data transmission, and VMR i is released * As a relay link. Alternatively, the method can be implemented in VMR i * Upon departure, the second trigger event is triggered again and the decision flow of fig. 8 is performed by the determination unit 101, e.g. to determine that the buffer is to serve the target UE.
On the other hand, as shown in the other branch of FIG. 8, ifI.e. VMR j before the service time of the buffer is exhausted * If it is reachable, the determining unit 101 determines the service continuity guarantee policy as providing the service to the target UE by the buffer. Fig. 12 and 13 show examples of the relevant information flow of this case. Fig. 12 shows a relevant information flow in the case where the buffer is the buffer of the target UE itself, and fig. 13 shows a relevant information flow in the case where the buffer is an edge buffer.
As shown in fig. 12, the information flow before decision making is the same as the corresponding part in fig. 9 and is not repeated here. After the decision, the gNB instructs the target UE to switch to its own buffer (also called local buffer), then the data transmission between the target UE and its own buffer is performed, and the VMR m is released as a link for the relay. Note that, in the case where the buffer is the buffer of the target UE itself, the information reporting process of the buffer is actually performed by the target UE.
In fig. 13, the information flow before decision making is the same as the corresponding part in fig. 9, and is not repeated here. After the decision, the gNB instructs the target UE to switch to the edge buffer and informs the edge buffer of the switch information. Then, a link connection is established between the target UE and the edge buffer for data transmission, and VMR m is released as a relay link.
In the above-described flow, in the case where the determination unit 101 determines to provide services to the target UE using the buffer, the implementation unit 102 is further configured to pre-fill the buffer before switching to the buffer. In this way, the service time of the buffer can be guaranteed.
In addition, in the non-real-time service communication scenario, the determining unit 101 is further configured to determine a service continuity guarantee policy for a user equipment (i.e., target UE) currently not served by the VMR, based on a remaining stay time of a VMR capable of providing a service among VMRs at the VMR service point, a remaining arrival time and a remaining stay time after arrival of the VMR to reach the VMR service point, and a service time of a buffer, in response to a third trigger event, that is, when the UE located within a coverage area of the VMR service point is not served by the VMR (hereinafter also referred to as target UE).
In this case, the target UE may be currently served directly by the base station or may be served by a buffer.
Similarly, in the case of the third trigger event, the gNB considers the state information of the VMR that is about to reach the VMR service point and the state information of the buffer in addition to the state information of the VMR at the VMR service point when making a decision, as compared to in the real-time service communication scenario. This is because, in case that no VMR can provide relay service temporarily, the buffer can provide service temporarily, so that the UE may not need to be directly connected to the gNB.
For ease of understanding, fig. 14 shows a schematic diagram of the flow of the operation of the determination unit 101, i.e. a schematic diagram of the decision process of the gNB. It should be understood that this decision process is exemplary only, and not limiting.
Upon occurrence of the third trigger event, each VMR at the VMR service point (including the newly arrived VMR, also referred to as the new VMR) estimates its own remaining residence time and reports the remaining residence time to the gNB, i.e., the VMR that is arriving at the VMR service point estimates its own remaining arrival time and remaining residence time after arrival and reports the remaining arrival time and remaining residence time to the gNB, and the buffer reports the buffer size and the buffer read rate to the gNB or the service time of the reporting buffer, as shown in the relevant information flow in fig. 15 (wherein the new VMR is shown as an example of the VMR at the VMR service point). Note that although the buffer is shown separately from the target UE in fig. 15, if the buffer is the buffer of the target UE itself, the information reporting process of the buffer is actually performed by the target UE. Illustratively, the base station may instruct the VMR and the buffer to report or the VMR and the buffer may report in response to the occurrence of the third trigger event.
Similarly, the VMR may estimate the remaining stay time and/or the remaining arrival time from its own location information and velocity information, etc., and the VMR that is about to arrive at the VMR service point may be, for example, a VMR that will arrive at the VMR service point within a predetermined time, which may be configured or preconfigured by the base station. The service time of the buffer may be the quotient of the buffer size divided by the buffer read rate. Furthermore, as previously mentioned, the VMR and/or the buffer may also periodically report its status information, neither of which is limiting.
As shown in fig. 14, first, the determination unit 101 determines whether the longest remaining stay time of the VMR capable of providing the service at the VMR service point is at a predetermined time threshold T 1 The above. If so, the determination unit 101 determines the service continuity guarantee policy as the VMR corresponding to the longest remaining stay time (e.g., denoted as VMR i * The residual residence time is) Will serve the target UE. Implementation unit 102 will instruct the establishment of the VMR i * The link with the target UE and the link between the base station and the target UE is released. Fig. 15 shows an example of the relevant information flow of this case. Note that in the description for the third trigger event, the VMR corresponding to the longest remaining stay time is assumed to be the new VMR. In this example, the target UE is currently served by the base station, and the determination unit 101 determines to switch it to the new VMR. It can be seen that the information flow in fig. 15 after the decision of the gNB is similar to fig. 7, and the detailed description is referred to above and will not be repeated here.
Fig. 16 and 17 show information flows in which the determination unit 101 determines to switch it to a new VMR in the case where the target UE is currently served by the buffer. The information flow before decision making is the same as the corresponding part in 15 and is not repeated here. Fig. 16 shows the flow of information for switching to a new VMR by the own buffer, and fig. 17 shows the flow of information for switching to a new VMR by the edge buffer. Note that, in the case where the buffer is the buffer of the target UE itself, the information reporting process of the buffer is actually performed by the target UE.
It can be seen that fig. 16 differs from fig. 15 in that no link release is required after switching to the new VMR, since no link establishment is required for data transfer between the target UE and its own buffer. Fig. 17 differs from fig. 16 in that after switching to the new VMR, the link between the target UE and the edge buffer needs to be released.
On the other hand, as shown in FIG. 14, the longest remaining residence time of VMR capable of providing service at the VMR service point is not at the predetermined time threshold T 1 In the above case, the determination unit 101 determines whether the target UE is currently served by the base station or the buffer. If the target UE is currently served by the base station, the determining unit 101 determines the service continuity guarantee policy as that the base station continues to serve the target UE and maintains a link between the base station and the UE.
If the target UE is currently served by the buffer, the determination unit 101 determines the VMR (denoted as VMR j) with the shortest remaining arrival time * ) Whether the remaining residence time after arrival of (a) is at a predetermined time threshold T 1 The above. If the determination is no, which indicates that the VMR is temporarily not suitable for providing the service, the determination unit 101 may determine the service continuity guarantee policy as to continue providing the service by the buffer. If the determination is yes, the determination unit 101 determines that there may be a VMR suitable for providing the service arriving, that VMR j * Remaining arrival time of (2)Whether or not it is greater than the service time t of the buffer b (t b =b/r). If->I.e. VMR j after the service time of the buffer has been exhausted * If the UE has not arrived, the determining unit 101 determines whether the target UE can be served by a base station (gNB). The determining unit 101 determines the service continuity guarantee policy as the base station (gNB) will serve the target UE if the target UE can be served by the base station. The implementation unit 102 will establish a link between the gNB and the target UE. The relevant information flow is shown in fig. 18 and 19. Fig. 18 shows the case where the buffer is a self buffer, and fig. 19 shows the case where the buffer is an edge bufferThe condition is as follows. The information flow before decision making is the same as the corresponding part in 16 and is not repeated here. In fig. 18, the gNB establishes a link connection with the target UE and performs data transmission. In fig. 19, it is also necessary to release the link between the target UE and the edge buffer. On the other hand, if the determination unit 101 determines that the target UE cannot be served by the base station (gNB), the determination unit 101 determines the service continuity guarantee policy as the new VMR having the longest remaining stay time will serve the target UE. Implementation unit 102 switches the target UE to the new VMR, and the information flow at this time can still be shown with reference to fig. 16 and 17.
In the other branch of FIG. 14, ifI.e. vmrj before the service time of the buffer is exhausted * Is reachable, the determination unit 101 determines that the service continuity guarantee policy continues to provide services for the buffer until the VMR j * Reaching the VMR service point. Note that it may be configured to maintain the buffer service, and subsequently trigger a fourth trigger event to switch to vmrj when the buffer is no longer available for service, i.e., the service time of the buffer is exhausted * May also be configured to automatically switch to VMR j when the buffer is no longer available for service, i.e., the service time of the buffer is exhausted * . Neither is it limiting.
In addition, in the non-real-time service communication scenario, the target UE is currently served by the buffer, and the determining unit 101 may be further configured to perform the determination of the service continuity guarantee policy in response to the fourth trigger event, that is, the buffer is no longer providing the service. Specifically, the longest remaining residence time of VMR capable of providing service at VMR service point is at a predetermined time threshold T 1 In the above case, the service continuity guarantee policy is determined as the VMR corresponding to the longest remaining residence time (denoted as VMR i * The residual residence time is) Serving the target UE and indicating to establish a link between the VMR and the target and release the original link; at VMR service point The longest remaining residence time of the VMR capable of providing service is at a predetermined time threshold T 1 In the following case, the service continuity guarantee policy is determined as that the base station will serve the target UE and establish a link between the base station and the target and release the original link.
In this case, since the buffer can no longer provide services, in order to ensure continuity of services, services can only be continued by the base station or the VMR existing at the VMR service point.
When a fourth trigger event occurs, each VMR at the VMR service point estimates its own remaining residence time and reports the remaining residence time to the gNB, and the buffer reports the buffer size and the buffer reading rate to the gNB or reports the service time of the buffer. Note that, in the case where the buffer is the buffer of the target UE itself, the information reporting process of the buffer is actually performed by the target UE. Illustratively, the base station may instruct the VMR and the buffer to report or the VMR and the buffer may report in response to the occurrence of the fourth trigger event. Furthermore, as previously mentioned, the VMR and/or the buffer may also periodically report its status information, neither of which is limiting.
FIG. 20 shows the target UE switching from its own buffer to VMR i * Fig. 21 shows an example of the information flow of the target UE being switched from the edge buffer to vmri * Is an example of the information flow of (a). In fig. 20 and 21, the gNB informs the target UE of the handover information, i.e., informs the target UE that it will switch to vmri * . And gNB and VMR i * A link connection is established to inform it of handover information. Then VMR i * Establishment of link connection with target UE, VMR i * And informing the gNB that the connection establishment is completed. Thus, a communication via VMR i is established between the target UE and gNB * As a relay data transmission link for data transmission. In fig. 21, it is also necessary to release the link between the target UE and the edge buffer.
Fig. 22 shows an example of an information flow of a target UE being handed over from its own buffer to a base station, and fig. 23 shows an example of an information flow of a target UE being handed over from an edge buffer to a base station. In fig. 22 and 23, the gNB establishes a link connection with the target UE and performs data transmission. In fig. 23, it is also necessary to release the link between the target UE and the edge buffer.
In this embodiment, a service continuity guarantee mechanism of the UE in the vehicle-mounted relay scenario is provided, and service continuity guarantee policies and information interaction flows under different trigger events are discussed respectively for the real-time service communication scenario and the non-real-time service communication scenario.
In summary, the electronic device 100 according to the present embodiment can determine the service continuity guarantee policy of the UE based on the state information of the VMR and/or the state information of the buffer and implement the policy in response to the trigger event, thereby effectively guaranteeing the service continuity of the user equipment and improving the user experience.
< second embodiment >
Fig. 24 shows a functional block diagram of an electronic device 200 according to a second embodiment of the application. As shown in fig. 24, the electronic apparatus 200 includes: a determining unit 201 configured to determine that at least one of a plurality of trigger events occurs; and a communication unit 202 configured to report status information of the VMR to the base station in response to the determination, wherein the plurality of trigger events includes: to leave the current VMR service point, the VMR reaches the current VMR service point.
The determining unit 201 and the communication unit 202 may be implemented by one or more processing circuits, which may be implemented as a chip, a processor, for example. Also, it should be understood that each functional unit in the electronic device shown in fig. 24 is merely a logic module divided according to the specific function it implements, and is not intended to limit the specific implementation.
The electronic device 200 may be disposed on the VMR side or communicatively connected to the VMR, for example. That is, the electronic apparatus 200 may be provided on the mobile base station side capable of serving as a relay. Here, it should also be noted that the electronic device 200 may be implemented at a chip level or may also be implemented at a device level. For example, the electronic device 200 may operate as a VMR or a mobile base station itself, and may also include external devices such as memory, transceivers (not shown), and the like. The memory may be used to store programs and related data information that the VMR or mobile station needs to perform to implement various functions. The transceiver may include one or more communication interfaces to support communication with different devices (e.g., UE, other VMR, base station (gNB), etc.), and the implementation of the transceiver is not particularly limited herein.
For example, the state information of the VMR may include one or more of the following: the remaining residence time of the VMR at the current VMR service point, the remaining arrival time and the remaining residence time after arrival of the VMR relative to the VMR service point, the location information of the VMR, the speed information of the VMR, the direction information of the VMR. For example, the VMR may estimate the remaining arrival time and the remaining residence time based on the position information of the VMR, the speed information of the VMR, the direction information of the VMR, and the like.
In one example, the determining unit 201 is configured to determine that the VMR is to leave the current VMR service point when the remaining residence time of the VMR at the current VMR service point is below a predetermined time threshold. The predetermined time threshold value here and the predetermined time threshold value T1 mentioned in the first embodiment may be the same or different in value.
In another example, the determining unit 201 may be further configured to determine that the VMR reaches the current VMR service point according to one or more of position information, speed information, and direction information of the VMR.
In addition, communication unit 202 may also periodically report the state information of VMR to the base station. Communication unit 202 may also report state information for the VMR in response to an indication by the base station. Neither is it limiting.
According to the electronic equipment provided by the embodiment, the state information of the VMR is reported to the base station, so that the base station can be assisted to determine the service continuity guarantee strategy of the UE and implement the strategy, the service continuity of the UE is effectively guaranteed, and the user experience is improved.
< third embodiment >
In describing the electronic device for wireless communication in the above embodiments, it is apparent that some processes or methods are also disclosed. Hereinafter, an outline of these methods is given without repeating some of the details that have been discussed above, but it should be noted that although these methods are disclosed in the course of describing an electronic device for wireless communication, these methods do not necessarily employ or are not necessarily performed by those components described. For example, embodiments of an electronic device for wireless communications may be implemented in part or in whole using hardware and/or firmware, while the methods for wireless communications discussed below may be implemented entirely by computer-executable programs, although such methods may also employ hardware and/or firmware of an electronic device for wireless communications.
Fig. 25 shows a flow chart of a method for wireless communication according to an embodiment of the application. The method comprises the following steps: determining a service continuity guarantee policy for UEs located within a coverage area of the VMR service point based on at least one of state information of the VMR and state information of the buffer in response to at least one of a plurality of trigger events (S11); and enforcing the service continuity guarantee policy (S12). The method may be implemented, for example, at the base station (gNB) side.
For example, the plurality of trigger events may include one or more of the following: the new UE enters the coverage range of the VMR service point; the VMR that is providing service is to leave the VMR service point; in the case that the UE located in the coverage of the VMR service point is not served by the VMR, the VMR that can provide the service reaches the VMR service point; and the buffer can no longer provide service.
Although not shown in the drawings, the above method may further include the steps of: a report of state information of the VMR is acquired from the VMR, and a report of state information of the buffer is acquired from the buffer. For example, the reporting of the state information of the VMR and/or the reporting of the state information of the buffer may be acquired in at least one of the following ways: periodically acquiring; acquired in response to the occurrence of a trigger event.
The buffers may be UE-own buffers and/or edge buffers.
The state information of the VMR includes, for example, one or more of the following: residual residence time of VMR at VMR service point, residual arrival time and residual residence time after arrival of VMR relative to VMR service point, position information of VMR, speed information of VMR, direction information of VMR. The status information of the buffer may include, for example, one or more of the following: buffer size, buffer read rate, service time of buffer.
In a real-time service communication scenario, a service continuity guarantee policy for the UE is determined based on a longest remaining residence time of a VMR capable of providing service at a VMR service point in response to at least one of a plurality of trigger events in step S11. For example, in the case where the longest remaining residence time is above a predetermined time threshold, determining a service continuity guarantee policy that a VMR corresponding to the longest remaining residence time will serve the UE and indicate that a link between the VMR and the UE is established; and determining a service continuity guarantee policy as the base station will serve the UE and establish or maintain a link between the base station and the UE if the longest remaining residence time is not above a predetermined time threshold.
Specifically, in the case that the trigger event is that a new UE enters the coverage area of the VMR service point, determining a service continuity guarantee policy for the new UE, and in the case that the trigger event is that the VMR that is providing service is to leave the VMR service point, the VMR that can provide service at the VMR service point is the VMR that can provide service among the remaining VMRs at the VMR service point; when the trigger event is that the VMR that can provide service reaches the VMR service point when the UE located in the coverage area of the VMR service point is not served by the VMR, the VMR that can provide service at the VMR service point is the VMR that reaches the VMR service point.
Further, in a non-real-time service communication scenario, in response to the new UE entering the coverage of the VMR service point, a service continuity guarantee policy for the new UE is determined based on the longest remaining residence time of the VMR capable of providing service at the VMR service point in step S11. Specifically, in the case where the longest remaining residence time is above the predetermined time threshold, determining the service continuity guarantee policy that the VMR corresponding to the longest remaining residence time will serve the new UE and indicating to establish a link between the VMR and the new user equipment in step S12; and in case the longest remaining residence time is not above the predetermined time threshold, determining a service continuity guarantee policy as the base station will serve the new UE and establishing a link between the base station and the new UE in step S12.
In the non-real-time service communication scenario, in response to the VMR that is providing the service leaving the VMR service point, a service continuity guarantee policy for the UE that is being served by the VMR that is leaving is determined in step S11 based on the remaining stay times of VMRs that are capable of providing the service among the remaining VMRs at the VMR service point, the remaining arrival times of VMRs that are to arrive at the VMR service point, and the remaining stay times after arrival, and the service time of the buffer.
Specifically, for example, as described with reference to fig. 8 in the first embodiment: in the case that the longest remaining residence time of the VMR capable of providing service at the VMR service point is above a predetermined time threshold, determining a service continuity guarantee policy that the VMR corresponding to the longest remaining residence time will serve the UE, and instructing to establish a link between the VMR and the UE and release a link between the VMR to be left and the UE; determining whether the remaining residence time after arrival of the VMR having the shortest remaining arrival time is above a predetermined time threshold in the case where the longest remaining residence time of the VMR capable of providing service at the VMR service point is not above the predetermined time threshold, and if not, determining a service continuity guarantee policy as that the base station will serve the UE and establishing a link between the base station and the UE; if yes, judging whether the residual arrival time of the VMR is greater than the service time of the buffer, determining a service continuity guarantee strategy as being provided by the buffer under the condition that the residual arrival time of the VMR is less than or equal to the service time of the buffer, further judging whether the UE can be served by the base station under the condition that the residual arrival time of the VMR is greater than the service time of the buffer, if the UE can be served by the base station, determining the service continuity guarantee strategy as being provided by the base station to serve the UE and establishing a link between the base station and the UE, and if the UE cannot be served by the base station, determining the service continuity guarantee strategy as being provided by the VMR under the condition that the residual arrival time of the VMR is greater than or equal to the sum of the service time of the buffer and the longest residual residence time of the VMR capable of providing service at the VMR service point, and continuing to provide the service by the VMR after the VMR is determined as being provided by the VMR under the condition that the residual arrival time of the VMR is less than the service time of the buffer and the longest residual residence time of the VMR capable of providing service at the VMR service point. Wherein, when the buffer is determined to provide service for the UE, the buffer is pre-filled before switching to the buffer.
In a non-real-time service communication scenario, in response to a UE located within the coverage of the VMR service point not being served by the VMR, the VMR that can provide the service arrives at the VMR service point in step S11, and a service continuity guarantee policy for the UE currently not served by the VMR is determined based on a remaining stay time of VMRs capable of providing the service among VMRs at the VMR service point, a remaining arrival time of VMRs to arrive at the VMR service point, and a remaining stay time after arrival, and a service time of a buffer.
Specifically, for example, as described with reference to fig. 14 in the first embodiment: in the case that the longest remaining residence time of the VMR capable of providing service at the VMR service point is above the predetermined time threshold, determining the service continuity guarantee policy that the VMR corresponding to the longest remaining residence time will serve the UE, and instructing to establish a link between the VMR and the UE and release the original link in step S12; if the longest remaining residence time of the VMR capable of providing service at the VMR service point is not above a predetermined time threshold, if the UE is currently served by the base station, maintaining a link between the base station and the UE, if the UE is currently served by the buffer, determining whether the remaining residence time after arrival of the VMR having the shortest remaining arrival time is above the predetermined time threshold, if the determination is negative, determining a service continuity guarantee policy as the buffer to continue providing service; if yes, judging whether the residual arrival time of the VMR is greater than the service time of the buffer, if yes, judging whether the UE can be served by the base station, determining a service continuity guarantee strategy as the base station to serve the UE and establishing a link between the base station and the UE under the condition that the UE can be served by the base station, and if not, determining the service continuity guarantee strategy as the VMR with the longest residual residence time in the VMR capable of providing service at the VMR service point to serve the UE; if the remaining arrival time of the VMR is less than or equal to the service time of the buffer, determining a service continuity guarantee policy as the buffer to continue providing service until the VMR reaches the VMR service point.
In a non-real-time service communication scenario, the UE is currently served by a buffer, in response to the buffer no longer providing service in step S11, determining a service continuity guarantee policy that a VMR corresponding to the longest remaining residence time will serve the UE in the case that the longest remaining residence time of a VMR capable of providing service at a VMR service point is above a predetermined time threshold, and in step S12, indicating to establish a link between the VMR and the UE and release the original link; in the case where the longest remaining residence time of the VMR capable of providing service at the VMR service point is below the predetermined time threshold, the service continuity guarantee policy is determined as the base station will serve the UE and establish a link between the base station and the UE and release the original link in step S12.
The above method corresponds to the electronic device 100 in the first embodiment, and specific details may refer to the first embodiment and will not be repeated here.
Fig. 26 shows a flow chart of a method for wireless communication according to another embodiment of the application.
