Description

UE ID determining method, UE ID range sending method, device and processor

Technical Field

The present invention relates to the field of communications, and in particular, to a method for determining a UE ID, a method for transmitting a UE ID range, a device, and a processor.

Background

In release 3GPP Rel-18, a Layer 2U (UE-to-UE) technology is introduced, i.e. Source End UE (User Equipment) communicates with Target End UE through Relay UE. For a Relay UE, a corresponding UE ID (UE Identification, UE identity acknowledgement) identifier needs to be carried in a transmitted data packet, so that the Relay UE can be mapped to an RLC (Radio Link Control, radio link layer control) entity of a corresponding PC5 interface (direct communication interface).

The Layer2U 2U of Rel-18 inherits the protocol stack of Rel-18 Layer2U 2N (UE-to-Network), namely an SRAP (Sidelink Relay Adaptation Protocol side-link Relay adaptation Layer protocol) Layer is added above the RLC Layer to add a local UE ID (UE ID) corresponding to a U2N Relay link. In Rel-17, the UE ID associated with Remote UE (Remote UE) is configured by the gcb, whereas in Rel-18, it is possible for the UE of Layer 2U to be outside the coverage area of the gcb, to be unable to interact with the gcb, only the UE ID can be configured by the UE itself in the Layer 2U link. For the same UE having multiple Layer 2U links, since UE IDs corresponding to different Layer 2U links are generated by different UE allocations, the UE IDs allocated by different links may be the same and thus collide, and the UE IDs need to be allocated again, thereby introducing additional signaling interaction and service setup delay.

Detailed Description

It should be noted that, in the case of no conflict, the embodiments and features in the embodiments may be combined with each other. The present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

In order to make the present application solution better understood by those skilled in the art, the following description will be made in detail and with reference to the accompanying drawings in the embodiments of the present application, it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, shall fall within the scope of the present application.

It should be noted that the terms "first," "second," and the like in the description and claims of the present application and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate in order to describe the embodiments of the present application described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

As described in the background art, in the prior art, the UE IDs allocated by different U2U Relay links are the same, so that a conflict occurs, and the UE IDs need to be allocated again, so that additional signaling interaction and service setup delay are introduced.

According to the embodiment of the application, a method for determining a UE ID and a method for transmitting a UE ID range are provided.

Fig. 1 is a flowchart of a method for determining a UE ID according to an embodiment of the present application. As shown in fig. 1, the method comprises the steps of:

s101, acquiring a UE ID range parameter based on a system message or RRC signaling, and/or a broadcast message, and/or a multicast message, where the UE ID range parameter is used to indicate a usable UE ID range.

In a specific implementation, the UE ID range parameter may be obtained based on a system message or RRC (Radio Resource Control ) signaling sent by the base station, or may be obtained based on a broadcast message sent by the sip link UE, or may be obtained based on a multicast message sent by the sip link UE.

For the Layer 2U Relay link, the coverage area is mainly improved, so that in a typical application of the Relay link, UEs of each Hop (Hop) have a certain distance interval, so that different UE ID range intervals can be configured for different first geographic areas, UE IDs generated by UEs of different location areas are not in the same range interval, and the technical problem that different UEs in the Layer 2U Relay network generate the same UE IDs and generate UE ID conflicts can be avoided as much as possible.

It should be specifically noted that, although the methods, apparatuses and processors corresponding to all embodiments of the present invention are provided for a Layer 2U Relay link, they are also applicable to a Layer 2U 2N Relay link, so that the Relay link is collectively used herein.

In a specific implementation, a plurality of groups of UE ID range parameters corresponding to different first geographic areas may be obtained based on a system message or RRC signaling, and/or a broadcast message, and/or a multicast message, where UE ID ranges corresponding to the plurality of groups of different first geographic areas do not overlap; and then determining the usable UE ID range based on the UE ID ranges corresponding to the multiple groups of different first geographic areas and the geographic position of the current UE.

It should be specifically noted that, if two sets of completely different UE ID ranges are received by the UE for the same first geographic area, for example, for the same first geographic area, the UE receives both the usable UE ID range sent by the base station through the system message or RRC signaling and the usable UE ID range sent by other sidlink UEs based on the broadcast message, and the two UE ID ranges are different, the UE may decide which set of UE ID ranges to use based on a preset priority rule and based on product implementation.

In specific implementation, when a cell is accessed, the current UE acquires UE ID range parameters corresponding to different first geographic areas based on a system message sent by a base station; the UE ID range parameters corresponding to the different first geographic areas may also be updated in real time based on a system message or RRC signaling periodically sent by the base station after the cell is accessed.

In a specific implementation, the range of UE IDs is fixed for a defined number of bits, and in order to increase the utilization of the UE ID range, when the indirection between two first geographical areas is greater than the second distance threshold, i.e. far enough away that UEs within the respective geographical areas do not occur in the same Relay link, part or all of the UE ID range may be reused for this case. Therefore, the different first geographic areas defined herein correspond to different UE ID ranges, which means that different first geographic areas satisfying the distance less than the first distance threshold need to correspond to different UE ID ranges, and for different first geographic areas indirectly greater than the second distance threshold, part or all of the UE ID ranges may be reused.

Different UE ID ranges are configured based on the first geographic area, then the UE ID is determined based on the different UE ID ranges, and the technical problem of UE ID conflict caused by the fact that different UE generate the same UE ID in different Relay links can be avoided, so that signaling interaction and service establishment time delay caused by the UE ID conflict are reduced.

In an implementation, since there may be overlapping regions between different first geographic regions, the current UE may be in overlapping regions of multiple first geographic regions, corresponding to multiple different UE ID ranges. When a plurality of different UE ID ranges are corresponding, a usable UE ID range may be determined based on a UE ID corresponding to the second Relay link, and the determined usable UE ID range does not include a UE ID corresponding to the second Relay link, where the second Relay link is another Relay link corresponding to the current UE and different from the first Relay link, that is, a UE ID range that does not collide with a UE ID of the second Relay link is selected.

In an embodiment of the present invention, the determining the available UE ID range based on the UE ID ranges corresponding to the multiple sets of different first geographic areas and the geographic location of the current UE includes: when the determined usable UE ID range includes a plurality of groups; deleting a UE ID range containing a UE ID corresponding to a second Relay link from a set of a plurality of groups of usable UE ID ranges, wherein the second Relay link is other Relay links which are corresponding to the current UE and are different from the first Relay link; a set of UE ID ranges is randomly selected from the remaining set of available UE ID ranges as the final available UE ID range.

In a specific implementation, if the corresponding UE ID ranges include the UE ID of the second Relay link, the UE ID range may be selected to be continuously used, or a request may be sent to other UEs of the first Relay link, and the UE ID may be further determined by the other UEs.

In an embodiment of the present invention, when the set of remaining usable UE ID ranges is empty, a request message may be sent to other nodes of the first Relay link, where the request message is used to request the other nodes to determine the UE ID.

When a plurality of different UE ID ranges are corresponding, the UE ID range which does not conflict with the UE ID of the second Relay link is selected, so that the conflict between the finally determined UE ID and the UE ID of the second Relay link can be avoided, and the probability of the UE ID conflict of the different Relay links is further reduced.

In a specific implementation, the different first geographic areas may be divided based on a circle, the different first geographic areas may be divided based on a sector, and the different first geographic areas may be divided based on other shapes such as a square.

In an embodiment, the different first geographic areas are partitioned based on circles, and the different first geographic areas are identified using a first geographic location of a center point of the circular area and a radius of the circular area. For example, as shown in fig. 4, three first geographic areas are divided: a first geographical area 1, a first geographical area 2 and a first geographical area 3. The center point (namely the circle center) of the first geographic area 1 is point A, and the radius is r1 (not identified in the figure); the center point of the first geographic area 2 is point B, and the radius is r2 (not identified in the figure); the center point of the first geographic area 3 is point C, and the radius is r3 (not identified in the figure); the first geographical area 1 may be identified by the geographical location of point a and the radius r1, the first geographical area 2 may be identified by the geographical location of point B and the radius r2, and the first geographical area 3 may be identified by the geographical location of point C and the radius r 3.

In an implementation, the geographic location of the center point may be represented using coordinates of the center point based on STD-2401 positioning criteria.

In an embodiment, the UE ID ranges corresponding to 3 different first geographic areas divided by circles are shown in table 1, where (x 1, y 1), (x 2, y 2), and (x 3, y 3) are geodesic distances in terms of longitude and latitude between the location of the center point corresponding to the 3 first geographic areas and the geographic coordinates (0, 0), and the calculation of x1, y1, x2, y2, x3, and y3 is in the prior art, and may refer to the STD-2401 positioning standard, which is not repeated in the present invention.

TABLE 1

In an embodiment of the present invention, the UE ID range parameter corresponding to the first geographic area includes: the geographic location of the center point corresponding to the first geographic area, the radius of the first geographic area, and the corresponding UE ID range.

The first geographic area is defined based on the geographic position of the center point and the radius of the geographic area, the first geographic area can be indicated with smaller signaling overhead, and meanwhile, the UE can calculate the geographic area conveniently.

In a specific implementation, for the sip multicast, since the multicast message may carry information related to a Zone ID (Zone ID), only UEs within the Zone ID range can receive the multicast message, so for the sip multicast, the UE ID range corresponding to the Zone ID Zone may be directly sent in the multicast message without indicating the corresponding first geographical Zone information, where the relevant definition of the Zone ID is as in the prior art, and reference may be made to the 38.331 protocol. That is, when determining a usable UE ID range based on the multicast message, the UE ID range corresponding to the multicast Zone ID area may be acquired based on the multicast message.

In an embodiment of the present invention, the multicast message carries a Zone ID area corresponding to the multicast message, and the obtaining the UE ID range parameter based on the multicast message includes: and acquiring the UE ID range corresponding to the Zone ID area based on the multicast message.

For Sidelink multicast, only the UE ID range is sent in the multicast message, and the corresponding first geographic area information is not required to be indicated, so that the signaling overhead for sending the UE ID range can be further saved, and the network resource utilization rate is improved.

Step S102, selecting a UE ID in the usable UE ID range, wherein the UE ID is used for indicating the RLC entity of the first Relay link corresponding to the current UE.

In a specific implementation, the current UE may select a UE ID from the usable UE ID range based on a UE ID corresponding to a second Relay link, where the selected UE ID is different from a UE ID corresponding to the second Relay link, and the second Relay link is another Relay link corresponding to the current UE and different from the first Relay link.

In an embodiment of the present invention, the selecting a UE ID from the usable UE ID range includes: and selecting a UE ID which is different from the UE ID corresponding to a second Relay link from the usable UE ID range, wherein the second Relay link is other Relay links which are different from the first Relay link and correspond to the current UE.

In a specific implementation, the current UE may be any UE in the first Relay link, that is, may be a Relay UE, may be a source UE, or may be a destination UE, and the present invention is not limited.

The UE ID is selected in the usable UE ID range, so that the range of the UE to select the UE ID can be limited, and the technical problem of UE ID conflict caused by the fact that different UEs randomly generate the same UE ID in different Relay links is avoided as much as possible, thereby reducing signaling interaction and service establishment time delay caused by the UE ID conflict.

It should be noted that the steps illustrated in the flowcharts of the figures may be performed in a computer system such as a set of computer executable instructions, and that although a logical order is illustrated in the flowcharts, in some cases the steps illustrated or described may be performed in an order other than that illustrated herein.

Fig. 2 is a flowchart of a method for transmitting a UE ID range according to an embodiment of the present application, as shown in fig. 2, the method includes the following steps:

s201, sending a UE ID range parameter through a system message or RRC signaling, so that the UE selects a UE ID in a usable UE ID range, wherein the UE ID range parameter is used for indicating the usable UE ID range, and the UE ID is used for indicating an RLC entity of a first Relay link corresponding to the UE.

In a specific implementation, the usable UE ID ranges may include UE ID ranges corresponding to multiple sets of different first geographic areas, where the UE ID ranges corresponding to the multiple sets of different first geographic areas do not overlap.

In a specific implementation, the first geographic area and other relevant definitions of the corresponding UE ID range refer to relevant descriptions of the corresponding embodiment of fig. 1, which are not repeated herein.

In a specific implementation, since the UE positions in the cell are dynamically changed, at a certain moment, there may be more UEs in the area 1, at a next moment, there may be fewer UEs in the area 1, and more UEs in the area 2, at this moment, the base station may dynamically adjust the UE ID range corresponding to the first geographic area according to the UE distribution in the first geographic area, that is, based on the number of UEs in the first geographic area, and then dynamically send the UE ID range corresponding to the first geographic area through a system message or RRC signaling.

In an embodiment of the present invention, the UE ID range corresponding to the first geographic area dynamically changes according to the number of UEs in the first geographic area.

In a specific implementation, the base station may periodically send the UE ID range corresponding to the first geographic area through a system message (when the UE ID range corresponding to the first geographic area changes, update the UE ID range corresponding to the first geographic area through the system message); and when the UE ID range corresponding to the first geographic area changes, sending the UE ID range corresponding to the first geographic area through RRC signaling.

In an embodiment, the UE ID range corresponding to the first geographic area may be dynamically adjusted based on the following method: when the number of the UE in the first geographic area is larger than a first number threshold, expanding the UE ID range corresponding to the first geographic area; and when the number of the UE in the first geographic area is smaller than a second number threshold, narrowing the range of the UE ID corresponding to the first geographic area, wherein the first number threshold is larger than the second number threshold.

In a specific implementation, when the UE ID range corresponding to the first geographic area needs to be enlarged, it needs to be ensured that the enlarged UE ID range does not overlap with the UE ID range corresponding to the geographic area surrounding the first geographic area. For example, as shown in fig. 4, when the UE ID range corresponding to the first geographic area 1 needs to be enlarged, it needs to be ensured that the enlarged UE ID range does not overlap with the UE ID ranges corresponding to the first geographic area 2 and the first geographic area 3, otherwise, the same UE ID may be selected by UEs in different first geographic areas, so that a conflict is generated.

In a specific implementation, when the UE ID range corresponding to the first geographic area needs to be enlarged, if the distance between the current first geographic area and other geographic areas is greater than the second distance threshold, that is, the distance is far enough, UEs in the respective first geographic areas will not appear in the same Relay link, so that no UE ID collision will occur, and part or all of the UE ID ranges in other geographic areas can be multiplexed.

In an embodiment of the present invention, when the UE ID range corresponding to the expanded first geographical area range overlaps with the UE ID range corresponding to the second geographical area range, the following needs to be satisfied: the minimum distance between any point in the second geographical area range and any point in the first geographical area range is greater than a preset position threshold, wherein the second geographical area is a different geographical area than the first geographical area.

According to the number of the UE in the first geographic area, the UE ID range corresponding to the first geographic area is dynamically adjusted, a larger UE ID range can be allocated to the first geographic area with a larger number of the UE, a smaller UE ID range can be allocated to the first geographic area with a smaller number of the UE, the utilization rate of the UE ID is improved, and the possibility of collision of the UE ID is further reduced.

The usable UE ID range is sent through the system message or the RRC signaling, so that the UE selects the UE ID in the usable UE ID range, the range of the UE to select the UE ID can be limited, the technical problem of UE ID conflict caused by the fact that different UEs randomly generate the same UE ID in different Relay links is avoided as much as possible, and signaling interaction and service establishment time delay caused by the UE ID conflict are reduced.

Fig. 3 is a flowchart of another method for transmitting a UE ID range according to an embodiment of the present application. As shown in fig. 3, the method comprises the steps of: and S301, transmitting a UE ID range parameter through a broadcast message and/or a multicast message, so that the UE selects a UE ID in a usable UE ID range, wherein the UE ID range parameter is used for indicating the usable UE ID range, and the UE ID is used for indicating an RLC entity of a first Relay link corresponding to the UE.

In a specific implementation, other relevant definitions of the UE ID range corresponding to the first geographic area refer to relevant descriptions of the embodiment corresponding to fig. 1, which are not described herein.

In a specific implementation, the UE ID range corresponding to the first geographic area may be dynamically adjusted based on the number of UEs in the first geographic area, and then the UE ID range corresponding to the first geographic area is dynamically sent through a broadcast message and/or a multicast message. The method for dynamically adjusting the UE ID range corresponding to the first geographic area may refer to the related description in the embodiment described in fig. 2, which is not described in detail herein.

Through broadcasting information and/or multicasting information, the usable UE ID range is transmitted, so that the UE selects the UE ID in the usable UE ID range, the range of the UE to select the UE ID can be limited, the technical problem of UE ID conflict caused by the fact that different UEs randomly generate the same UE ID in different Relay links is avoided as much as possible, and signaling interaction and service establishment time delay caused by the UE ID conflict are reduced.

The embodiment of the application also provides a UE ID determining device, and it should be noted that the UE ID determining device of the embodiment of the application may be used to execute the UE ID determining method provided by the embodiment of the application.

In an embodiment of the present invention, the obtaining unit 51 is configured to: when the determined usable UE ID range includes a plurality of groups; deleting a UE ID range containing a UE ID corresponding to a second Relay link from a set of a plurality of groups of usable UE ID ranges, wherein the second Relay link is other Relay links which are corresponding to the current UE and are different from the first Relay link; a set of UE ID ranges is randomly selected from the remaining set of available UE ID ranges as the final available UE ID range.

In an embodiment of the present invention, the obtaining unit is configured to: when the set of remaining usable UE ID ranges is empty, a request message may be sent to other nodes of the first Relay link, where the request message is used to request the other nodes to determine a UE ID.

In an embodiment, the different first geographical areas are divided based on circles, and the different first geographical areas are identified using the geographical location of the center point of the circular area and the radius of the circular area. For example, as shown in fig. 4, three first geographic areas are divided: a first geographical area 1, a first geographical area 2 and a first geographical area 3. The center point (namely the circle center) of the first geographic area 1 is point A, and the radius is r1 (not identified in the figure); the center point of the second geographical area 2 is point B and the radius is r2 (not identified in the figure); the center point of the third geographic area 3 is point C, and the radius is r3 (not identified in the figure); the first geographical area 1 may be identified by the geographical location of point a and the radius r1, the first geographical area 2 may be identified by the geographical location of point B and the radius r2, and the first geographical area 3 may be identified by the geographical location of point C and the radius r 3.

The first geographic area is defined based on the geographic position of the center point and the radius of the geographic area, so that the first geographic area can be indicated with smaller signaling overhead, and meanwhile, the UE can calculate the first geographic area conveniently.

In an embodiment of the present invention, the selecting unit 52 is configured to select, from the available UE IDs, a UE ID that is different from a UE ID corresponding to a second Relay link, where the second Relay link is another Relay link that is different from the first Relay link and corresponds to the current UE.

Fig. 6 is a schematic diagram of a UE ID range transmitting apparatus according to an embodiment of the present application. As shown in fig. 6, the apparatus 60 includes: a first sending unit 61, configured to send a UE ID range parameter through a system message or RRC signaling, so that a UE selects a UE ID in a usable UE ID range, where the UE ID range parameter is used to indicate a usable UE ID range, and the UE ID is used to indicate an RLC entity of a first Relay link corresponding to the UE.

In a specific implementation, the range of UE IDs is fixed for a defined number of bits, and in order to increase the utilization of the UE ID range, when the indirection between two first geographical areas is greater than the second distance threshold, i.e. far enough away that UEs within the respective first geographical areas do not occur in the same Relay link, part or all of the UE ID range may be reused for this case. Therefore, the different first geographic areas defined herein correspond to different UE ID ranges, which means that different first geographic areas satisfying the distance less than the first distance threshold need to correspond to different UE ID ranges, and for different first geographic areas indirectly greater than the second distance threshold, part or all of the UE ID ranges may be reused.

In an implementation, since the UE location in the cell is dynamically changed, at a certain moment, there may be more UEs in the area 1, at a next moment there may be fewer UEs in the area 1, and more UEs in the area 2, where the UE ID range transmitting apparatus 60 may further include: the first adjusting unit 62 is configured to dynamically adjust, according to the UE distribution in the first geographic area, that is, based on the number of UEs in the first geographic area, the UE ID range corresponding to the first geographic area, and then the first transmitting unit 61 dynamically transmits, through a system message or RRC signaling, the UE ID range corresponding to the first geographic area.

In a specific implementation, the first sending unit 61 may periodically send the UE ID range corresponding to the first geographic area through a system message (when the UE ID range corresponding to the first geographic area changes, update the UE ID range corresponding to the first geographic area through a system message); and when the UE ID range corresponding to the first geographic area changes, sending the UE ID range corresponding to the first geographic area through RRC signaling.

In an embodiment, the first adjustment unit 62 may dynamically adjust the UE ID range corresponding to the first geographic area based on the following method: when the number of the UE in the first geographic area is larger than a first number threshold, expanding the UE ID range corresponding to the first geographic area; and when the number of the UE in the first geographic area is smaller than a second number threshold, narrowing the range of the UE ID corresponding to the first geographic area, wherein the first number threshold is larger than the second number threshold.

As shown in fig. 7, the apparatus 70 includes: a second sending unit 71, configured to send, by using a broadcast message and/or a multicast message, a UE ID range parameter, so that the UE selects a UE ID in a usable UE ID range, where the UE ID range parameter is used to indicate the usable UE ID range, and the UE ID is used to indicate an RLC entity of the first Relay link corresponding to the UE.

In a specific implementation, the UE ID range sending device 70 may further include: the second adjusting unit 72 is configured to dynamically adjust the UE ID range corresponding to the first geographical area based on the number of UEs in the first geographical area, and then dynamically send the UE ID range corresponding to the first geographical area through a broadcast message and/or a multicast message. The method for dynamically adjusting the UE ID range corresponding to the first geographic area may refer to the related description in the embodiment described in fig. 2, which is not described in detail herein.
