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.

It should be noted that, all actions for acquiring signals, information or data in the present disclosure 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.
Before describing the embodiments of the present disclosure in detail, the following description is first made of an application scenario of the present disclosure, and the present disclosure may be applied to a communication system as shown in fig. 1, fig. 1 is a block diagram of a communication system shown in an exemplary embodiment of the present disclosure, and as shown in fig. 1, the communication system may include a terminal (terminal) 101 and an access network device 102. In some embodiments, the access network device 102 (access network device, AN device) may also be referred to as a "radio access network device (radio access network device, RAN device)", "Base Station (BS)", "radio base station (radio base station)", "fixed station)", and in some embodiments may also be referred to as a "node", "access point", "transmission point (transmission point, TP)", "Reception Point (RP)", "transmission and/or reception point (transmission/reception point), TRP)", "panel", "antenna array", "cell", "macrocell", "microcell", "femto cell", "pico cell", "sector", "cell group", "serving cell", "carrier", "component carrier (component carrier)", bandwidth part (BWP), etc. In some embodiments, the terminal 101 may be referred to as a "User Equipment (UE)", "user terminal" (MS) "," Mobile Terminal (MT) ", subscriber station (subscriber station), mobile unit (mobile unit), subscriber unit (subscriber unit), wireless unit (wireless unit), remote unit (remote unit), mobile device (mobile device), wireless device (wireless device), wireless communication device (wireless communication device), remote device (remote device), mobile subscriber station (mobile subscriber station), access terminal (access terminal), mobile terminal (mobile terminal), wireless terminal (wireless terminal), remote terminal (remote terminal), hand-held device (handset), user agent (user), mobile client (client), etc. The technical solution of the present disclosure may be applicable to NSA architecture, in the process of establishing an LTE-NR (Long Term Evolution-New Radio ) dual connection, the 5G terminal may determine whether the cell supports high-level indication according to whether the upper layer indication-r15 in SIB2 (System Information Block Type) is 1, further, in the case of supporting high-level indication, the 5G icon is displayed, and meanwhile, the terminal 101 may also determine whether to limit the 5G connection according to the value of an attach accept (attach accept message) or a field limit dcnr (limit dual connection) in tracking area update accept (tracking area update accept message) sent by the network to the UE, in the case of limiting the 5G connection, the limit dual connection is indicated by the limit dcnr being 1, and in the case of limiting the 5G connection, the terminal cannot utilize the 5G network resource, so that the 5G icon is not displayed. In the case where the retrievdcnr is 0, it means that the dual connection is not limited, i.e., the 5G connection is supported, and in the case where the 5G connection is supported, the terminal can simultaneously utilize 4G and 5G network resources through the dual connection between the LTE base station and the 5G NR base station, and can prompt the user of the current network condition by displaying a 5G icon. However, the inventor finds that in the actual network configuration process, when the network sends SIB2 to the terminal, the upper layer indication-r15=1 (indicating that the dual connection is supported) is included in the tracking area update accept message or the attach accept message, but the network carries the retrievdcnr=1 (indicating that the dual connection is limited), which can cause the terminal to fail to connect to the 5G network in the case that the current serving cell supports the dual connection, so that 4G and 5G network resources cannot be utilized simultaneously, and the user intuitively experiences that the terminal cannot utilize the 5G network, and in the same serving cell, the 5G icon is just displayed and then not displayed, which is definitely unfavorable for guaranteeing the reliability of the terminal networking, and is unfavorable for improving the user experience of the terminal.
In order to solve the above technical problems, the present disclosure provides a network registration method, apparatus, device and storage medium, where the method receives a system message broadcasted by an access network device of a specified cell, where the system message includes a first high-layer indication parameter, where the first high-layer indication parameter is used to indicate whether the specified cell supports high-layer indication; acquiring first capability information according to the system message, wherein the first capability information is used for indicating whether the designated cell supports dual connectivity; generating second capability information according to the cell identifier of the designated cell under the condition that the first capability information characterizes that the designated cell does not support dual-connectivity and the first high-level indication parameter characterizes that the designated cell supports high-level indication, wherein the second capability information is used for indicating that the designated cell supports dual-connectivity; and registering the terminal to the appointed cell according to the second capability information. Therefore, the first capability information of the appointed cell can be effectively corrected to be inconsistent with the actual capability through the second capability information registration of the appointed cell, so that the network capability of the appointed cell is limited, the problem of utilizing network resources by the terminal is further limited, the networking performance of the terminal can be effectively improved, and the user experience of the terminal is facilitated to be improved.
Embodiments of the present disclosure are described in detail below in conjunction with specific examples.
FIG. 2 is a flow chart of a network registration method shown in an exemplary embodiment of the present disclosure; as shown in fig. 2, the network registration method, applied to a terminal, may include the steps of:
step 201, receiving a system message broadcast by an access network device of a designated cell, where the system message includes a first high-layer indication parameter, where the first high-layer indication parameter is used to indicate whether the designated cell supports high-layer indication.
The first high-layer indication parameter may be a value of an upper layer indication-r15 field in SIB2 (System Information Block Type 2, system message block 2), and the system message may be that the terminal performs cell search on a specific frequency band to detect a nearby cell signal; after the terminal detects the cell signal, it starts to receive the system information blocks SIBs (usually including a plurality of SIBs) broadcasted by the base station, and after the SIBs are received, the value of the first higher layer indication parameter, that is, the upper layer indication-r15 field is obtained by decoding the SIBs.
It should be noted that, the network may transmit an indication or configuration information of dual connectivity support to the terminal through the high-level indication (Upper Layer Indication) to guide the behavior or function of the terminal under the corresponding condition; the indication may relate to a functional configuration, a priority setting, a constraint, etc. When the network sends high-level instructions to the terminal, the terminal recognizes and analyzes the instructions, and performs corresponding operation or function adjustment according to the instructions so as to meet the requirements of the network or optimize the performance of the terminal. For example, when the network requires the terminal to support LTE and 5G dual connectivity, the terminal supporting the higher layer indication feature may establish dual connectivity with the LTE base station and the 5G base station according to the dual connectivity indication conveyed by the network.
Step 202, obtaining first capability information according to the system message, where the first capability information is used to indicate whether the specified cell supports dual connectivity.
In an exemplary embodiment, the present step may be implemented by steps S1 to S3 in fig. 3 (fig. 3 is a flowchart of a network registration method according to the embodiment shown in fig. 2), and as shown in fig. 3, step 202 in fig. 1 may include:
s1, sending an access request message to the access network equipment according to the system message.
The access Request message may be an Attach Request message or a tracking area update Request (Tracking Area Update, TAU) message.
It should be noted that, when the terminal receives a system message broadcast by the access network device, the system message includes a plurality of system information blocks SIBs, the SIBs are decoded to obtain decoded network parameters, the terminal selects an optimal cell as a cell to be accessed according to the network parameters provided in the SIB, such as signal strength, quality, frequency configuration, and the like, and sends an Attach Request (Attach Request) message to the access network device corresponding to the cell to be accessed, so as to Request connection with the cell to be accessed and complete the attachment process, where the Attach Request generally includes identity information, request type, security parameters, and the like of the terminal. After receiving the attachment request sent by the terminal, the cell to be accessed performs corresponding authentication and configuration, and sends an attachment Accept (Attach Accept) message to the terminal as confirmation of attachment success. The attach accept message contains acknowledgement of the terminal by the network and some additional information. After receiving the attach accept message, the UE performs corresponding processing, updates the security parameters, obtains the temporary identifier, and so on. Once the UE completes the attachment process, it can obtain complete network access and service, and can perform operations such as data transmission, receiving incoming calls, sending short messages, etc.
In addition, the Tracking Area update request (Tracking Area Update, TAU) message is information that the terminal notifies the network of its own current location, and may be issued when the terminal moves to a new Tracking Area (Tracking Area) to update the Tracking Area to which it belongs or notify the network of the location change. And after the network receives the tracking area updating request message of the terminal, the network performs verification and processing. The network may check the identity, location information, security verification, etc. of the terminal and decide whether to accept the request according to network policies and configurations. And generates and transmits Tracking Area Update Accept message in response to the tracking area update request of the terminal. The message contains an acknowledgement of acceptance of the terminal request by the network and may carry some relevant configuration or update information.
S2, receiving an access response message sent by the access network equipment according to the access request message.
The access response message may be an Attach Accept message or a Tracking Area Update Accept (tracking area update Accept) message.
S3, acquiring the first capability information from the access response message.
The first capability information may be information of a restractdcnr field in an Attach Accept message or a Tracking Area Update Accept message, for example, in the case of restractdcnr=1 or restractdcnr=true, indicates a restricted dual connection, and in the case of restractdcnr=0 or restractdcnr=f, indicates an unrestricted dual connection.
Through the steps shown in S1 to S3, the first capability information for indicating whether the designated cell supports dual connection can be effectively obtained, and reliable data basis can be provided for subsequent network registration and connection.
Step 203, when the first capability information characterizes that the designated cell does not support dual connectivity, and the first high-level indication parameter characterizes that the designated cell supports high-level indication, generating second capability information according to the cell identifier of the designated cell, where the second capability information is used to indicate that the designated cell supports dual connectivity.
Wherein the second capability information may include a cell identity and a character for indicating that dual connectivity is supported.
It should be noted that, through a lot of experiments, it is generally proven that in the case of a cell system message, specifically, upper layerindication-r15=1 in SIB2, the cell supports dual connectivity, but the network of the cell is generally configured to limit dual connectivity in the registration process due to the fact that the restractdcnr=1, which belongs to a network configuration error, affects network performance, and causes that the terminal cannot simultaneously utilize 5G resources, in order to solve the problem, the present disclosure generates the second capability information locally, and stores the second capability information locally, that is, generates information for indicating that the specified cell supports dual connectivity, for example, may be restractdcnr=0 or restractdcnr=f.
And step 204, registering the terminal to the designated cell according to the second capability information.
It should be noted that, in the cell registration process, the second capability information may limit the behavior and the capability of the terminal in the registration process. For example, the RestrictDCNR may play a role in: data transmission mode limitation, when the retrievdcnr is configured to 1, the terminal may be limited by the data transmission mode during the registration process, which means that after the terminal establishes the RRC connection, the terminal may only perform data transmission through the designated data transmission mode, and other transmission modes may be limited or disabled. Data path selection limit: the configuration of the retrievdcnr may also limit the data path selection by the UE during the registration process, which means that the UE may only select a specific data path for data transmission after establishing the RRC connection, while other paths may be limited or disabled. Function usage restriction: in addition to limitations in terms of data transmission, the RestrictDCNR may also limit the use of specific functions by the UE during registration. This includes restricting the use of specific protocol functions, service functions or other network functions. That is, by configuring the retrievdcnr, the network can finely control the behavior and capability of the terminal during cell registration. The method is beneficial to the network to adjust the registration behavior of the terminal according to the current network condition and strategy, and optimize the utilization of network resources and the performance of the terminal.
According to the technical scheme, the appointed cell is registered through the second capability information, the first capability information of the appointed cell can be effectively corrected to be inconsistent with the actual capability, so that the network capability of the appointed cell is limited, the problem that the terminal utilizes network resources is further limited, the networking performance of the terminal can be effectively improved, and the user experience of the terminal is facilitated to be improved.
Optionally, the method further comprises:
and under the condition that the terminal is in a communication connection state with the appointed cell, if the number of times of connection failure with the NR cell in a preset time period is greater than or equal to a preset number of times threshold, determining a target cell to be switched, and switching the service cell of the terminal from the appointed cell to the target cell.
The above embodiment for determining the target cell to be switched may include: acquiring target network parameters of adjacent cells of the designated cell and first network signal strength of the designated cell, wherein the target network parameters at least comprise second high-layer indication parameters and second network signal strength, and the second high-layer indication parameters are used for indicating whether the adjacent cells support high-layer indication or not; and under the condition that the second high-level indication parameter characterization supports high-level indication, if the difference value between the second network signal strength and the first network signal strength is larger than or equal to a preset difference value threshold, the adjacent cell is used as the target cell.
When it is determined that the terminal is in a communication connection state with the specified cell, if the number of times of connection failure with the NR cell in the preset time period is greater than or equal to the preset number of times threshold, it can be characterized that the connection stability of the terminal with the 5G network of the specified cell is poor, or the 5G network performance of the specified cell is poor, so that a cell with better 5G network performance can be selected as the current serving cell. Therefore, the reliability of terminal communication can be effectively improved, and the utilization rate of 5G resources is improved.
FIG. 4 is a flow chart illustrating another network registration method according to the embodiment shown in FIG. 2; as shown in fig. 4, the method may further include:
in step 205, in case it is determined that the specified cell belongs to a non-anchor cell, a target cell to be handed over is determined.
The implementation manner of determining that the specified cell belongs to the non-anchor cell in this step may include:
under the condition that the terminal is in an idle state, if the designated cell is determined to not support high-level indication through the first high-level indication parameter, determining that the designated cell belongs to the non-anchor cell; or if the terminal is determined to be in a communication connection state with the designated cell, determining that the designated cell belongs to the non-anchor cell if the terminal is determined to not have a connection with an NR cell.
The above-described embodiment of determining a target cell to be handed over may include: acquiring target network parameters of adjacent cells of the designated cell and first network signal strength of the designated cell, wherein the target network parameters at least comprise second high-layer indication parameters and second network signal strength, and the second high-layer indication parameters are used for indicating whether the adjacent cells support high-layer indication or not; and under the condition that the second high-level indication parameter characterization supports high-level indication, if the difference value between the second network signal strength and the first network signal strength is larger than or equal to a preset difference value threshold, the adjacent cell is used as the target cell.
And 206, switching the service cell of the terminal from the designated cell to the target cell.
According to the technical scheme, the service cell of the terminal can be switched from the designated cell to the target cell under the condition that the designated cell is determined to belong to the non-anchor cell, the reliability of double connection of the terminal can be effectively guaranteed, the networking performance of the terminal is improved, and then the utilization rate of the terminal to network resources can be effectively improved.
FIG. 5 is a flow chart illustrating yet another network registration method according to the embodiment shown in FIG. 2; as shown in fig. 5, the method may further include:
Step 207, if it is determined that the first high-level indication parameter characterizes that the designated cell does not support high-level indication and the first capability information characterizes that the designated cell does not support dual-connectivity, third capability information is generated if it is determined that the terminal establishes a connection with an NR cell, where the third capability information includes a cell identifier of the designated cell, a first high-level indication parameter used to characterize that the designated cell supports high-level indication, and first capability information used to characterize that the designated cell supports dual-connectivity.
For example, the third capability information may be shown in table 1, where pci_1 and pci_2 are cell identities, and upper layer indication-r15=1 indicates that a higher layer indication is supported, i.e. dual connectivity is supported, and restrictdcnr=0 indicates that dual connectivity is not limited, i.e. 5G connectivity is supported.
