Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.
It should be noted that, all actions for acquiring signals, information or data in the present application are performed under the condition of conforming to the corresponding data protection rule policy of the country of the location and obtaining the authorization given by the owner of the corresponding device.
It should be noted that, the network registration method in the embodiment of the present application may be applied to network registration in a non-independent networking. The non-independent networking can be understood as two base stations of 1 core network band. For example, in the fifth generation of mobile communication technology: in 5G NR (new radio), the core network (EPC) of LTE, LTE base stations, and 5G base stations (gNB) may be used for networking, or the core network (5 GC) of 5G, LTE base stations, and 5G base stations (gNB) may be used for networking.
In order to facilitate understanding of the embodiments of the present application, the embodiments of the present application will mainly be described by taking the fifth generation mobile communication technology as an example without specific description. However, it will be appreciated that the network registration method of embodiments of the present application may also be extended to other generation mobile communication technologies, such as fourth generation mobile communication technology or sixth generation mobile communication technology, where possible.
Before describing embodiments of the present application in detail, concepts related to the embodiments of the present application will be explained.
The 5G NR (New Radio) is a global 5G standard based on a completely New air interface design of Orthogonal Frequency Division Multiplexing (OFDM), and is also a very important cellular mobile technology base of the next generation. As 3GPP adopts this standard, the term NR is followed, becoming another proxy for 5G, just as the 4G wireless standard is described in LTE (long term evolution).
SA, standby, independent networking, for example, in the fifth generation mobile communication technology, networking is performed by using a 5G base station (gNB) and a 5G core network (5 GC).
NSA, non-standby, non-independent networking, for example, in the fifth generation mobile communication technology, EN-DC mode, that is, networking is performed by using the core network (EPC) of LTE, the LTE base station, and the 5G base station (gNB).
EN-DC, E-UTRA-NRDual Connectivity, namely, a 4G base station is used as a first accessed base station to transmit signaling, and a 5G base station is used as an extended and enhanced data transmission channel, so that the data transmission rate is improved.
LTE, (Long Term Evolution ) is a long term evolution of The UMTS (Universal Mobile Telecommunications System ) technical standard established by The 3GPP (The 3rd Generation Partnership Project, third generation partnership project) organization.
The measurement event refers to a notification event for measuring signal quality. In some embodiments, the measurement event may be, for example, a B1 measurement event, i.e. the neighbor cell quality is above a certain threshold, for measuring a high priority inter-system cell.
Anchor point cell, first registered cell in base station accessed by terminal. For example, in the EN-DC mode of the fifth generation mobile communication technology, the base station to which the terminal is first connected is an LTE base station, and at this time, the anchor cell is the cell first registered in the LTE base station, and at the same time, the base station corresponding to the anchor cell is the LTE base station, and at this time, the target secondary cell to be added subsequently is the NR cell. For another example, in the networking mode using the core network (5 GC) of 5G, the LTE base station, and the 5G base station (gNB), the base station to which the terminal is first connected is the NR base station, and at this time, the anchor cell is the cell registered first in the NR base station, and at the same time, the base station corresponding to the anchor cell is the NR base station, and at this time, the target secondary cell added subsequently is the LTE cell.
In the related art, the premise of registering a terminal in an independent networking network is that the terminal can perform signal quality measurement on a frequency point to be measured based on a measurement event configured by a base station corresponding to an anchor point cell and report a measurement result. The base station corresponding to the anchor point cell can determine whether the cell corresponding to the reported frequency point to be tested is SCG (Secondary Cell Group, auxiliary cell group) according to the measurement result reported by the terminal. Specifically, after the terminal resides in the anchor cell, the base station corresponding to the anchor cell configures a measurement event for the terminal, adds an auxiliary cell for the terminal, and registers the terminal with the non-independent networking network, that is, the process of registering the terminal with the non-independent networking network can be regarded as the process of adding the auxiliary cell by the terminal.
In the EN-DC mode in the non-independent networking mode of the fifth generation mobile communication technology, the precondition that the terminal registers the non-independent networking network is that the terminal performs signal quality measurement on the frequency point to be measured and reports the measurement result based on the B1 measurement event configured by the base station corresponding to the LTE anchor cell. The base station corresponding to the LTE anchor cell determines whether to add an NR cell as an SCG according to the measurement result reported by the terminal (Secondary Cell Group ).
However, the applicant has found in long-term studies that the following problems sometimes occur in the current network: after the terminal resides in the anchor point cell, the base station corresponding to the anchor point cell does not configure a measurement event for the terminal due to certain abnormality, so that the terminal cannot register in the non-independent networking network.
Therefore, how to reduce the problem that the terminal can not register to the non-independent networking network is a long-standing research and exploration problem in the field of mobile communication.
Therefore, the embodiment of the present disclosure provides a network registration method, where in a case where a measurement event configured by a base station corresponding to an anchor cell is not received within a preset period of time after a terminal resides in the anchor cell, a target measurement event may be obtained from an association relationship between a pre-stored cell and the measurement event, so that even in a case where the measurement event configured by the base station corresponding to the anchor cell is not received, the measurement event may be actively triggered to be executed, so as to facilitate the terminal to perform non-independent networking network registration, thereby reducing a problem that the terminal cannot register to the non-independent networking network.
It should be noted that, the terminal mentioned in the embodiment of the present disclosure may be a 5G terminal, that is, a terminal supporting a 5G network, where the 5G terminal may support networks such as 2G, 3G, and 4G besides the 5G network, and the 5G terminal may also support a 5G network in both SA (independent networking) and NSA (non-independent networking) modes.
The network access method according to the embodiments of the present disclosure is described in detail below with reference to the accompanying drawings.
Fig. 1 is a flowchart illustrating a network registration method according to an exemplary embodiment, which may be applied to a terminal including a mobile phone, a notebook, a tablet computer, a desktop computer, a smart speaker, a smart television, a wearable device, a smart robot, a vehicle-mounted terminal, and the like. The method comprises the following steps:
s110, determining to camp on the anchor cell.
In some embodiments, the terminal may read the system message, initiate a camping request to the anchor cell, and determine to camp on the anchor cell after receiving a camping power message returned by the anchor cell.
In some embodiments, the terminal may initiate a camping request to the anchor cell under the conditions of power-on network search registration, cell reselection, cell handover, and handover IDLE state.
S120, if the measurement event configured by the base station corresponding to the anchor cell is not received in a preset time period after the anchor cell is resided, and a target measurement event associated with the anchor cell exists in the association relation between the pre-stored cell and the measurement event, acquiring the target measurement event.
In combination with the foregoing, it can be known that, after the terminal resides in the anchor cell, the base station corresponding to the anchor cell will normally configure a measurement event for the terminal within a certain time, and in an abnormal situation, the base station corresponding to the anchor cell will not configure a measurement event for the terminal.
In some embodiments, after determining to camp on the anchor cell, the terminal may start a Timer timer_b1 for a preset period of time, for example, a 30s Timer, so as to determine whether a configured measurement event is received within the preset period of time after camping on the anchor cell. Alternatively, the preset time period may be obtained by counting the time when the terminal receives the configured measurement event after camping on the anchor cell under normal conditions.
In the embodiment of the disclosure, if the terminal does not receive the configured measurement event within a preset period of time after the terminal resides in the anchor cell, for example, the configured measurement event of the anchor cell is not received until the timer expires, it may be determined that an abnormal situation occurs, and an additional path needs to be taken to obtain the measurement event. At this time, it may be further determined whether or not there is a target measurement event associated with the anchor cell in the association relationship between the cell and the measurement event stored in advance, and if there is a target measurement event associated with the anchor cell, the target measurement event may be acquired.
In some embodiments, the target measurement event associated with the anchor cell may be derived based on measurement events configured by the base station to which the anchor cell corresponds when the terminal historically resides.
In some embodiments, the anchor cell may be uniquely determined by the frequency point of the cell and the cell identity (earfcn, pcb).
S130, executing the target measurement event to obtain an execution result.
In the embodiment of the disclosure, after acquiring the target measurement event, the terminal may execute the target measurement event and obtain an execution result. Alternatively, the execution result may reflect the measured signal quality of the cell.
And S140, when the execution result meets the preset condition, sending the execution result to the base station corresponding to the anchor point cell, so that the base station corresponding to the anchor point cell determines a target auxiliary cell according to the execution result, wherein the target auxiliary cell is used for indicating the terminal to register the non-independent networking network.
The target auxiliary cell and the anchor point cell are cells of different network systems, namely the target auxiliary cell and the anchor point cell are cells corresponding to different network systems.
In the embodiment of the present disclosure, a preset condition may be set, and when the execution result meets the preset condition, the execution result may be sent to the base station corresponding to the anchor cell. Therefore, the base station corresponding to the anchor point cell can determine the target auxiliary cell according to the execution result and send the access information corresponding to the target auxiliary cell to the terminal, so that the terminal can register the non-independent networking network according to the received access information of the target auxiliary cell, and network transmission can be performed based on the anchor point cell and the target auxiliary cell at the same time after the terminal completes the registration of the non-independent networking network, namely after the terminal is added with the target auxiliary cell.
In some embodiments, the preset condition may be that the signal quality of the cell under test meets a set signal quality threshold.
By adopting the method, if the configured measurement event is not received in the preset time period after the anchor cell is resided, and the target measurement event associated with the anchor cell exists in the association relation between the pre-stored cell and the measurement event, the target measurement event can be acquired and executed, an execution result is obtained, and then the execution result can be sent to the base station corresponding to the anchor cell when the execution result meets the preset condition, so that the base station corresponding to the anchor cell determines the target auxiliary cell for the terminal to register the non-independent networking network according to the execution result. Under the condition that the configured measurement event is not received in a preset time period after the anchor cell is resided, the target measurement event can be obtained from the association relation between the cell and the measurement event which are stored in advance, so that the measurement event can be actively triggered and executed even under the condition that the configured measurement event is not received in the preset time period, the terminal can be conveniently assisted to register with the non-independent networking network, and the problem that the terminal cannot register with the non-independent networking network is solved.
In addition, in the 5G network, considering that the characteristic of 5G is a large transmission rate, and the transmission rate required by the processes of signaling, emergency call, response paging, initial network access and the like is not large, the 4G network may be considered to be continuously used, so, in order to improve the 5G NR benefit, in some implementations, the method of the embodiments of the present disclosure may further include the steps of: generating a resident request for characterizing a data cause based on the data transmission request; the step of sending a camping request to the anchor cell, in which case the foregoing step of determining to camp on the anchor cell may specifically include: and in response to receiving a stay active message returned by the anchor cell, determining to stay to the anchor cell, wherein the stay active message is generated by a base station corresponding to the anchor cell based on a stay request.
In the embodiment of the disclosure, the terminal can generate a residence request for characterizing the data reason when having a data transmission request, and send the residence request to the anchor cell. The anchor cell, upon receiving the camping request, may process the camping request, e.g., allocate RNTI (Radio Network Temporary Identifier, radio network temporary identity), radio resources, and other resources, and after processing is complete, return a camping power message to the terminal. Thus, after receiving the camp-on successful message, the terminal may determine to camp on the anchor cell in response to the camp-on successful message.
Alternatively, the park request may be an RRC connection setup request.
For example, when the terminal needs to transmit video and image data in an uplink, the terminal may generate an RRC connection establishment request with a mo data cause value and send the RRC connection establishment request including the mo data cause value to the anchor cell. Here, mo data (mobile start data, when uplink is required to be transmitted) is a cause value identifier corresponding to a data cause.
In some embodiments, the terminal may be a terminal supporting NR dual connectivity when in EN-DC mode in a non-independent networking. Thus, a field characterizing that the terminal capability supports NR dual links may also be carried in the generated RRC connection setup request. For example, the value of the DCNR field in the RRC connection setup request is set to 1.
In addition, in other embodiments, the terminal may also generate a residence request to register with the non-independent networking network during the processes of signaling, emergency call, paging response, initial network access, and the like. That is, in other embodiments, the terminal may also generate the park request with a cause value such as emergency call, highpriority access, mo-signaling, e.g., attach/location update/random access, etc.
Furthermore, it may be understood that the measurement event may include frequency point information of the cell to be measured and a signal quality threshold, in which case, performing the target measurement event to obtain an execution result may include the steps of: and carrying out signal quality measurement based on the frequency point information included in the target measurement event to obtain the signal quality of each cell under the frequency point information. Correspondingly, when the execution result meets the preset condition, the execution result is sent to the base station corresponding to the anchor cell, so that the base station corresponding to the anchor cell determines a target auxiliary cell according to the execution result, and the method can include the steps of: and when the signal quality is larger than the preset signal threshold value included in the target measurement event, sending the candidate cell and the corresponding signal quality to the base station corresponding to the anchor cell, so that the base station corresponding to the anchor cell determines the target auxiliary cell based on each signal quality.
In the embodiment of the disclosure, when the terminal executes the target measurement event, the terminal may perform signal quality measurement on each cell under the frequency point information (for example, carrier freq-r 15) included in the target measurement event, so as to obtain the signal quality of each cell under the frequency point information. Wherein r15 represents the version number of the 5G NR standard, i.e. the 5G NR first edition standard r15.
And then, comparing the signal quality of each cell with a preset signal threshold value included by a target measurement event, if the signal quality of a certain cell is greater than or equal to the preset signal threshold value, determining the cell as a candidate cell, and finally transmitting all the candidate cells and the corresponding signal quality to a base station corresponding to an anchor cell, thereby completing the process of reporting an execution result by the terminal.
Then, after receiving the candidate cells and the corresponding signal quality reported by the terminal, the base station corresponding to the anchor cell can further determine the target secondary cell based on the signal quality corresponding to each candidate cell. The process of registering the terminal with the non-independent networking network can be understood as a process that the base station corresponding to the anchor cell configures the target secondary cell for the terminal according to the candidate cell and the corresponding signal quality.
Alternatively, the signal quality may be at least one of the three signal indicators nr-RSRP, nr-RSRQ, nr-SINR.
It should be noted that, the signal type corresponding to the preset signal threshold corresponds to the type of the measured signal quality. For example, when the preset signal threshold is for nr-RSRP, then nr-RSRP of each cell is measured, and for example, when the preset signal threshold is for nr-RSRP and nr-RSRQ, respectively, then nr-RSRP and nr-RSRQ of each cell are measured.
Where NR-RSRP, i.e., NR-SS-RSRP, refers to the NR secondary synchronization reference signal received power (new radio-Synchronization Signal-Reference Signal Received Power, NR-SS-RSRP).
NR-RSRQ, i.e., NR-SS-RSRQ, refers to the NR secondary synchronization reference signal received quality (new radio-Synchronization Signal-Reference Signal Receiving Quality, NR-SS-RSRQ).
NR-SINR refers to the measured signal-to-noise (interference) ratio of NR secondary synchronization signal acquisition. In combination with the foregoing, when the configured measurement event is not received within a preset period of time after the terminal resides in the anchor cell, it may be further determined whether a target measurement event associated with the anchor cell exists in the pre-stored association relationship, and in a practical situation, the determination result may also be that the target measurement event associated with the anchor cell does not exist in the association relationship, for example, the terminal has not historically resided in the anchor cell, so in some implementations, the method of the embodiment of the disclosure may further include the following steps:
if the configured measurement event is not received in a preset time period after the anchor cell is resided, and the target measurement event associated with the anchor cell does not exist in the association relation between the pre-stored cell and the measurement event, determining that the registration of the non-independent networking network fails.
In the embodiment of the disclosure, if the configured measurement event is not received within a preset time period after the terminal resides in the anchor cell, and the target measurement event associated with the anchor cell does not exist in the association relationship between the pre-stored cell and the measurement event, it may be indicated that the terminal cannot acquire the measurement event associated with the anchor cell, and in this case, it may be determined that the registration of the non-independent networking network fails, that is, the terminal temporarily cannot register the non-independent networking network.
In this case, whether the target measurement event associated with the anchor cell exists in the association relationship or not can be executed according to the normal process of registering the non-independent networking network by the terminal, that is, the terminal executes the configured measurement event to obtain an execution result, and when the execution result meets the preset condition, the execution result is sent to the base station corresponding to the anchor cell, so that the base station corresponding to the anchor cell determines the target auxiliary cell according to the execution result.
In addition, in order to enable the target measurement event corresponding to the anchor cell to be queried later when an abnormal situation occurs, in addition to the process of registering the non-independent networking network according to the normal terminal, the target measurement event corresponding to the anchor cell may be recorded, so in some implementations, the method of the embodiment of the disclosure may further include the steps of:
If the configured measurement event is received in a preset time period after the anchor point cell is resided, and the target measurement event associated with the anchor point cell does not exist in the association relationship, the association relationship between the anchor point cell and the configured measurement event is established.
In the embodiment of the disclosure, when the terminal receives the configured measurement event in a preset time period after the terminal resides in the anchor cell, there may be two other cases, where the terminal never resides in the anchor cell in history, in this case, no measurement event associated with the anchor cell exists in the association relationship, and at this time, the measurement event associated with the anchor cell in the current non-independent networking network registration process may be recorded, that is, the association relationship between the anchor cell and the configured measurement event is established, so that when the subsequent terminal does not receive the configured measurement event in the preset time period after the terminal resides in the anchor cell, the target measurement event corresponding to the anchor cell may be obtained from the association relationship.
In addition, as can be seen from the foregoing, when the terminal receives the configured measurement event in the preset period after the terminal resides in the anchor cell, another situation may exist, that is, there is a measurement event associated with the anchor cell in the association relationship, in this case, in addition to executing according to a normal procedure of registering the non-independent networking network by the terminal, the measurement event corresponding to the anchor cell may also be replaced with the measurement event associated with the anchor cell in the association relationship, so in some embodiments, the method of the embodiment of the disclosure may further include the steps of:
If the configured measurement event is received in a preset time period after the anchor point cell is resided, and a target measurement event associated with the anchor point cell exists in the association relation, determining whether the configured measurement event and the target measurement event have differences or not;
if the configured measurement events and the target measurement events have differences, replacing the target measurement events in the association relationship by the configured measurement events to obtain the association relationship between the anchor point cell and the configured measurement events.
In the embodiment of the disclosure, in consideration of that the base station may be updated, maintained, adjusted, etc., so that the base station frequency point or the access standard is changed, when the terminal receives the configured measurement event in a preset time period after the terminal resides in the anchor cell, if there is a target measurement event associated with the anchor cell in the association relationship, it may further determine whether there is a difference between the target measurement event and the measurement event configured this time, if there is no difference, it is not necessary to update and replace the target measurement event, and if there is a difference, it may update and replace the target measurement event by using the configured measurement event, so as to obtain the association relationship between the anchor cell and the configured measurement event. For example, the target measurement event associated with the anchor cell in the stored association relationship is directly replaced by the configured measurement event.
Furthermore, in combination with the foregoing, it is known that the base station frequency point or the access standard may change at different times of camping on the anchor cell, and thus, in some embodiments, determining the difference between the configured measurement event and the target measurement event may include the steps of:
