[0066] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0067] Regarding the device in the above embodiment, the specific manner in which each module performs operations has been described in detail in the embodiment of the method, and will not be elaborated here.

[0068] like Figure 1 As shown, a method for updating UE capabilities is provided, the method comprising the following steps:

[0069] Step S11: In response to the NR capability update of the user equipment UE, an attachment request is sent to the network side entity, wherein the attachment request carries the NR capability information of the UE after the capability update.

[0070] The method described in the embodiments of the present disclosure is applied to a user device; the user device may be a mobile phone, a computer, a server, a transceiver device, a tablet device, a medical device, a wearable device, etc.

[0071] The network side entity here may be a core network entity; for example, it may be a common mobility management entity (Mobility Management Entity, MME) in a packet core network (Evolved Packet Core, EPC), an access and mobility management function (Access and Mobility Management Function, AMF) entity in a 5G core network, and the like.

[0072] The network side entity here may also be an access network entity; for example, it may be a base station, an access point device, etc.

[0073] The network side entity here can be a physical entity or a logical entity.

[0074] The NR capability information here includes but is not limited to the following:

[0075] Capability information for supporting NR;

[0076] NR capability information is not supported.

[0077] In an application scenario, the capability information of supporting NR is the capability information of supporting 5G, and the capability information of not supporting NR is the capability information of not supporting 5G. For example, the capability information of supporting NR here can turn on the 5G switch for the UE, and the capability information of not supporting NR here can turn off the 5G switch for the UE.

[0078] In one embodiment, sending the attachment request includes sending an attachment request signaling (Attach requestMsg).

[0079] In one embodiment, the NR capability information is carried in the DCNR field of the attachment request signaling. For example, if the DCNR field carries 1, it is used to indicate that the NR capability information is capability information that supports NR; if the DCNR field carries 0, it is used to indicate that the NR capability information is capability information that does not support NR.

[0080] Of course, in other embodiments, the NR capability information may also be carried in a specific field of the attachment request signaling. The specific field carried in the specific field may be determined based on the communication protocol or the specific field may be a field that has not yet been assigned specific indication content, which is not limited here.

[0081] Of course, in other embodiments, the method for updating UE capabilities may also be: in response to the wireless capability update of the UE, sending an attach request carrying the UE capability information of the UE to a network side entity.

[0082] The UE wireless capability information here may be at least one of the following:

[0083] Capability information of supporting 4G or not supporting 4G;

[0084] Capability information of supporting 3G or not supporting 3G;

[0085] Information about the capability of a Subscriber Identification Module (SIM) card in the UE to support NR;

[0086] The capability information of supporting a network generation higher than 5G network or the capability information of not supporting a network generation higher than 5G network.

[0087] The NR capability update of the UE here includes but is not limited to at least one of the following:

[0088] Updated from supporting NR capabilities to not supporting NR capabilities;

[0089] Updated from the capability of supporting NR to the capability of supporting NR;

[0090] The capability of switching from one SIM card supporting NR to another SIM card supporting NR in the UE.

[0091] In one embodiment, the UE may be a UE including at least one SIM card. For example, the UE may be a UE including two or more SIM cards. In this way, the UE's NR capability information update may be capability information for switching from one SIM card supporting NR to another SIM card supporting NR.

[0092] Of course, in other embodiments, the method for updating the NR capability of the UE may also be to update the wireless capability of the UE; wherein the updating of the UE capability may also include but is not limited to at least one of the following:

[0093] Updated from the capability of supporting networks of a generation higher than 5G networks to the capability of not supporting networks of a generation higher than 5G networks;

[0094] Updated from a capability that does not support networks of a generation higher than 5G networks to a capability that supports networks of a generation higher than 5G networks;

[0095] Updated from supporting 4G capabilities to not supporting 4G capabilities;

[0096] Updated from capabilities not supporting 4G to capabilities supporting 4G;

[0097] Update from supporting 3G capability to not supporting 3G capability;

[0098] Update the capability from not supporting 3G to supporting 3G;

[0099] Updated from supporting NR capabilities to supporting 4G capabilities;

[0100] Updated from supporting 4G capabilities to supporting NR capabilities;

[0101] Updated from supporting NR capabilities to supporting 3G capabilities;

[0102] The capability to support 3G is updated to the capability to support NR.

[0103] In an embodiment of the present disclosure, an attachment request carrying the NR capability information of the UE may be sent by the UE, that is, the UE may report its own NR capability information through the attachment request, so that the network side entity can know the NR capability information of the UE.

[0104] Moreover, the present invention reports the NR capability information through an attachment request, which can greatly shorten the time for receiving the confirmation message based on the NR capability information from the network side, compared with the case where the network fails to receive the confirmation message or the reception of the confirmation message is slow because the NR capability information is reported through a tracking area update request. This can increase the speed at which the UE connects to the network, greatly shorten the delay in resuming UE data transmission, and thus improve the user experience satisfaction.

[0105] Furthermore, only when the NR capability of the UE is updated, an attachment request carrying the updated NR capability information is sent. In this way, the network side entity can know the NR capability information after the capability update, while reducing the signaling overhead of sending the attachment request in real time, saving the power consumption and energy consumption of the UE, etc.

[0106] Of course, in other embodiments, the step S11 may also be: periodically sending the attachment request to the network side entity. Thus, in this example, the NR capability information may be reported periodically.

[0107] Of course, in other embodiments, the step S11 may also be: when the cell where the UE resides changes, the attachment request is sent to the network side entity. Thus, in this example, when the location of the UE changes, the NR capability information is likely to change, and thus sending the attachment request based on this can enable the network side entity to know the NR capability information after the location changes.

[0108] In some embodiments, the method further comprises:

[0109] Perform detachment;

[0110] The S11 includes:

[0111] After detaching, sending the attach request to the network side entity.

[0112] In one embodiment, the step S10 includes: sending a detachment signaling (Detach request Msg).

[0113] After detaching, the UE will immediately request to attach in order to communicate, hoping to reconnect to the network. The time from detaching to reattaching is very short, so this method can still speed up the reporting of NR capability information.

[0114] For example, in one embodiment, the UE sends a detach signaling to the core network entity. The detach signaling here is used to instruct the UE to disconnect the network connection.

[0115] In the embodiment of the present disclosure, the UE may first perform a detach operation to disconnect the UE from the network, and then reconnect to the network based on an attach request.

[0116] In another embodiment, the method for updating UE capabilities includes:

[0117] Sending a detach request, wherein the detach request carries the NR capability information of the UE;

[0118] Reattachment is performed within a predetermined time range after the detach request is sent.

[0119] The sending of the detach request here may be sending a detach signaling.

[0120] Thus, in this example, the NR capability information of the UE can be sent through the detach message, so that the network side entity knows the NR capability information and disconnects the UE from the network. And, reattachment is performed within a predetermined time of sending the detach request message, so that the UE re-registers with the network.

[0121] like Figure 2 As shown, in some embodiments, the method further includes:

[0122] The step S11 comprises:

[0123] Step S111: In response to the NR capability update of the UE and the cell in which the UE resides being an abnormal cell, sending the attachment request to the network side entity.

[0124] The abnormal cell here is a cell that cannot receive a confirmation message returned based on a tracking area update request, or a cell that receives a confirmation message returned based on a tracking area request for more than a predetermined time threshold.

[0125] like Figure 3 As shown, in some embodiments, the method further includes:

[0126] Step S10: Send a tracking area update request;

[0127] Step S12: In response to the time for receiving a confirmation message returned based on the tracking area update request exceeding a first time threshold, determining that the cell where the UE resides is an abnormal cell; or, in response to not receiving a confirmation message returned based on the tracking area update request within a second time threshold, determining that the cell where the UE resides is an abnormal cell.

[0128] In one embodiment, the tracking area update request is a tracking area update request signaling (Tracking area update request MSg).

[0129] In one embodiment, the NR capability information is carried in the DCNR field of the tracking area update request signaling. For example, if the DCNR field carries 1, it is used to indicate that the NR capability information is capability information that supports NR; if the DCNR field carries 0, it is used to indicate that the NR capability information is capability information that does not support NR.

[0130] Of course, in other embodiments, the NR capability information may also be carried in a specific field of the tracking area update request signaling. The specific field carried in the information may be determined based on the communication protocol or the specific field may be a field that has not yet been assigned specific indication content, which is not limited here.

[0131] In the embodiment of the present disclosure, the tracking area update request may not carry NR capability information, or may carry NR capability information.

[0132] The first time threshold here may be greater than N seconds, and N is a positive number greater than 1. For example, in one embodiment, N is a positive number greater than 5 seconds.

[0133] The second time threshold here may be greater than M seconds, and M is a positive number greater than 1. For example, in one embodiment, M is a positive number greater than 5 seconds.

[0134] In the disclosed embodiment, it is possible to first detect whether the cell where the UE resides is an abnormal cell. For example, the UE sends a tracking area update request. If the confirmation message returned based on the tracking area update request is received for more than the first time threshold, it is considered that the cell reports the NR capability information through the tracking area update request very slowly, and the cell is determined to be an abnormal cell.

[0135] For another example, if a confirmation message based on the tracking area update request is not received within the second time threshold range by sending a tracking area update request through the UE, it is considered that the cell cannot receive the confirmation message returned through the tracking area message, and the cell is determined to be an abnormal cell. In this way, if the cell where the UE resides is an abnormal cell, the NR capability information can be reported based on the attachment request, so that the confirmation message of the attachment request can be quickly received, so that the UE can quickly register with the network to resume data transmission.

[0136] Of course, in other embodiments, the cell may be detected in advance, and if the cell is determined to be an abnormal cell, when the UE's location is updated to the cell, it is determined to directly send the attachment request carrying the updated capability information.

[0137] In some embodiments, in response to the time of receiving the confirmation message returned based on the tracking area update request exceeding the first time threshold, determining that the cell in which the UE resides is an abnormal cell includes:

[0138] In response to the fact that the number of times that the time of receiving the returned confirmation message exceeds the first time threshold is greater than the first predetermined number of times within the timing time of the timer, it is determined that the cell where the UE resides is an abnormal cell.

[0139] The confirmation message returned here is the confirmation message returned based on the tracking area update request.

[0140] The first predetermined number of times here is an integer greater than 1. For example, in one embodiment, the first predetermined number of times is 5 times.

[0141] The timing time of the timer here is greater than the first time threshold. For example, in one embodiment, the timing time of the timer is 1 minute.

[0142] For example, in one embodiment, the UE sets the timing time of the timer to 1 minute; the first time threshold is 5 seconds. The UE starts the timer. Within the timing time of the timer, the first tracking area update request is sent, and the confirmation message returned based on the first tracking area update request is recorded; if the confirmation message returned based on the first tracking area update request is received for more than 5 seconds, the number of times recorded is 1; if the confirmation message returned based on the first tracking area update is received for less than 5 seconds, the number of times recorded is 0. Then the second tracking area update request is sent, and the confirmation message returned based on the second tracking area update request is recorded; if the confirmation message returned based on the second tracking area update request is received for more than 5 seconds, the number of times recorded is accumulated by 1; if the confirmation message returned based on the second tracking area update request is received for less than 5 seconds, the number of times recorded remains unchanged. And so on, until the timing time of the timer ends; if the recorded number of times is greater than the first predetermined number of times, it is determined that the cell where the UE resides is an abnormal cell.

[0143] Thus, in the embodiment of the present disclosure, the number of times that the confirmation message returned by the UE based on the tracking area update request in the cell where the UE resides is greater than the first time threshold within a period of time (i.e., the timing time of the timer) can be recorded, and if the number is greater than the first predetermined number, the cell is determined to be an abnormal cell. In this way, the inaccurate situation of determining that the cell is an abnormal cell due to a single detection that the confirmation message time returned based on the tracking area update request exceeds the first time threshold can be reduced, thereby greatly improving the accuracy of detecting whether the cell where the UE resides is an abnormal cell.

[0144] In some other embodiments, in response to not receiving a confirmation message returned based on the tracking area update request within a second time threshold range, determining that the cell in which the UE resides is an abnormal cell includes:

[0145] In response to the fact that the number of times that a confirmation message returned based on the tracking area update request is not received within a second time threshold range is greater than a second predetermined number of times within the timing time of the timer, it is determined that the cell where the UE resides is an abnormal cell.

[0146] The confirmation message returned here is the confirmation message returned based on the tracking area update request.

[0147] The second predetermined number of times here is an integer greater than 1. For example, in one embodiment, the second predetermined number of times is 3 times.

[0148] The timing time of the timer here is greater than the second time threshold. For example, in one embodiment, the timing time of the timer is 50 seconds.

[0149] For example, in one embodiment, the UE sets the timing time of the timer to 50 seconds; the second time threshold is 8 seconds. The UE starts the timer. Within the timing time of the timer, the first tracking area update request is sent; if the confirmation message based on the first tracking area update request is not received within 8 seconds after the first tracking area update request is sent, it is determined that the confirmation message is not received, and the number of times recorded is 1; if the confirmation message based on the first tracking area update request is received within 8 seconds after the first tracking area update request is sent, the number of times recorded is 0. Then the second tracking area update request is sent; if the confirmation message based on the second tracking area update request is not received within 8 seconds after the second tracking area update request is sent, it is determined that the confirmation message is not received, and the number of times recorded is accumulated by 1; if the confirmation message based on the second tracking area update request is received within 8 seconds after the second tracking area update request is sent, the number of times recorded remains unchanged. And so on, until the timing time of the timer ends; if the recorded number of times is greater than the second predetermined number of times, it is determined that the cell where the UE resides is an abnormal cell.

[0150] In practical applications, the second time threshold range herein refers to receiving a confirmation message returned based on the tracking area update request, which can be considered as: being unable to receive a confirmation message returned based on the tracking area update request.

[0151] Thus, in the embodiment of the present disclosure, the number of times that the UE does not receive a confirmation message returned based on a tracking area update request in the cell where it resides within a period of time can be recorded, and if the number is greater than a second predetermined number, the cell is determined to be an abnormal cell. Thus, the situation where the cell is determined to be an abnormal cell due to a single detection of not receiving a confirmation message returned based on a tracking area update request and the inaccuracy occurs can be reduced, thereby greatly improving the accuracy of detecting whether the cell where the UE resides is an abnormal cell.

[0152] Of course, in other embodiments, if the cell where the UE resides is not an abnormal cell, the UE can still send a tracking area update request carrying NR capability information.

[0153] For example, in some embodiments, the method further comprises:

[0154] In response to the NR capability update of the UE and the cell in which the UE resides is not an abnormal cell, a tracking area update request carrying the updated NR capability information is sent to the network side entity.

[0155] The cell where the UE resides here is not an abnormal cell, including one of the following:

[0156] In response to the time of receiving the determination message returned based on the tracking area update request not exceeding the first time threshold, determining that the cell in which the UE resides is not an abnormal cell;

[0157] In response to being able to receive a determination message returned based on the tracking area update request within a second time threshold range, determining that the cell where the UE resides is not an abnormal cell;

[0158] In response to the fact that the time of receiving a confirmation message returned based on the tracking area update request does not exceed the first time threshold at least once within the timing time of the timer, it is determined that the cell where the UE resides is not an abnormal cell.

[0159] In the disclosed embodiment, when the cell where the UE resides is not an abnormal cell, it can also send a tracking area update request carrying updated capability information to inform the network side entity of the NR capability information. In this way, since the cell where the UE resides is not an abnormal cell, the network environment of the cell is relatively good, and the time to receive the confirmation message based on the tracking area update request is relatively short; thus, the UE can be registered with the network in a relatively short time, thereby restoring the data transmission between the UE and the network side entity and improving the user experience.

[0160] like Figure 4 As shown, in some embodiments, the step S11 includes:

[0161] Step S112: In response to the NR capability update of the UE and no confirmation message based on the tracking area update request is received within a predetermined time threshold, sending the attachment request to the network side entity; wherein the tracking area update request is sent by the UE.

[0162] The predetermined time range here may be the same as the second time threshold in the above embodiment, or may be different from the second time threshold in the above embodiment.

[0163] In the disclosed embodiment, it is not necessary to pre-detect whether the cell where the UE resides is an abnormal cell; instead, when the UE resides in a certain cell, it is determined that the UE's NR capability is updated and no confirmation message based on the tracking area update request is received within a predetermined time range, an attachment request carrying the updated NR capability information is directly sent. In this way, the time for the UE to reattach to the network can be greatly shortened, thereby accelerating the recovery of data transmission between the UE and the network side entity and improving user experience satisfaction.

[0164] like Figure 5 As shown, in some embodiments, the S11 includes:

[0165] Step S113: In response to the NR capability update of the UE and the operator to which the UE belongs is a specific operator, sending the attachment request; wherein the specific operator is an operator configured to send the attachment request.

[0166] The operator to which the UE belongs here may be China Mobile, China Unicom, China Telecom or China Netcom, etc.

[0167] For example, in one embodiment, if the mobile operator is an operator configured to send an attach request, when the NR capability of the UE is updated, the UE sends an attach request carrying the updated NR capability information.

[0168] For example, in other embodiments, if the Unicom operator is the operator configured to send a tracking area update request, when the NR capability of the UE is updated, the UE sends a tracking area update request carrying the NR capability of the UE after the update.

[0169] In the embodiment of the present disclosure, the attach request carrying the updated NR capability information is sent only when the operator to which the UE belongs is the operator configured to send the attach request. In this way, the embodiment of the present disclosure can select a suitable request message to send the updated NR capability information based on the attributes of the operator to which the UE belongs; thereby, the service characteristics of the operator can be taken into account while speeding up the UE's registration to the network.

[0170] The following provides specific examples in combination with any of the above embodiments:

[0171] Example 1

[0172] Figure 6 A method for updating UE capabilities is provided, the method comprising the following steps:

[0173] Step S21: Counting the number of times that the time for receiving a confirmation message returned based on a tracking area update request exceeds a first time threshold;

[0174] In an optional embodiment, the UE responds to the NR capability information update; the UE starts a timer, and within the timing of the timer, counts the time of each reception of a confirmation message returned based on a tracking area update request; if the time of receiving a confirmation message returned based on a tracking area update request exceeds a first time threshold, the number of determinations is accumulated by 1.

[0175] In another embodiment, the step S21 may also be: counting the number of times that a confirmation message based on the tracking area update is not received within the second time threshold. Thus, when the confirmation message is not received within the second time threshold, it is determined that the network side entity will not reply with a confirmation message based on the tracking area update request.

[0176] Step S22: Determine whether the number exceeds a first predetermined number; if so, execute step S23; if not, execute step S24;

[0177] In an optional embodiment, the UE determines whether the number of records exceeds a first predetermined number; if so, execute step S23, and if not, execute step S24.

[0178] In an optional embodiment, the first predetermined number of times is 5 times.

[0179] Step S23: Send an attach request carrying the NR capability information after the NR capability is updated;

[0180] In an optional embodiment, the UE sends an attachment request carrying the updated NR capability information to the core network entity.

[0181] In an optional embodiment, the step S23 further includes: determining that the cell where the UE resides is an abnormal cell. In this way, if the UE resides in the abnormal cell next time, it is determined that the UE sends an attach request carrying the NR capability information after the capability update.

[0182] Step S24: Send a tracking area update request carrying the NR capability information after the NR capability is updated;

[0183] In an optional embodiment, the UE sends a tracking area update request carrying the updated NR capability information to the core network entity.

[0184] In an optional embodiment, the step S24 further includes: determining that the cell where the UE resides is not an abnormal cell. In this way, if the UE resides in the cell that is not an abnormal cell next time, it is determined that the UE sends a tracking area update request carrying the NR capability information after the capability update.

[0185] In the disclosed embodiment, by detecting the tracking area update request mode of the cell where the UE resides, when it is determined that the network side entity frequently replies to the confirmation message of the tracking area update request slowly or does not reply to the confirmation message of the tracking area update request, the updated NR capability information can be sent based on the attachment request. In this way, the UE can quickly receive the confirmation message of the reply to the attachment request; thereby enabling the UE to quickly register with the network, facilitating the rapid recovery of the UE's data transmission, etc., and improving the user's experience satisfaction.

[0186] Alternatively, when it is determined that the network side entity frequently replies to the confirmation message of the tracking area update request relatively quickly, the tracking area update request can still be used to send the updated NR capability information. In this way, the UE can still quickly receive the confirmation message of the reply tracking area update request; thereby enabling the UE to quickly register with the network, facilitating the rapid recovery of the UE's data transmission, etc., and improving the user experience satisfaction.
