For example, an eSIM may be selected by a source terminal to initiate a VoNR call to a target terminal even if the selected eSIM has poor channel quality or experiences interference at the target terminal. Selecting an eSIM that favors the source terminal over the target terminal may cause poor call effects.

The invention provides a platform data optimization processing method based on a 5G communication technology. Fig. 1 is a flowchart of a platform data optimization processing method based on a 5G communication technology according to an embodiment of the present invention.

When the source terminal determines which eSIM is used when the VoNR call is initiated to the target terminal, the source terminal not only considers the information of the source terminal, but also considers the information of the target terminal. For example, the target terminal uses the first eSIM for better signal quality, but the second eSIM has lower signal quality. The target terminal indicates the signal quality of each eSIM to the source terminal in the subscription information, which helps the source terminal determine which eSIM to use when VoNR calls the target terminal. The subscription information includes various information related to the target terminal, such as subscription information of the target terminal. The target terminal selects which information is shared with the source terminal through the configuration interface.

The source terminal receives the subscription information and determines an eSIM to be used based on the subscription information. Alternatively, the source terminal determines which eSIM to use based on a combination of the source terminal subscription information and the target terminal subscription information. Alternatively, the user selects the eSIM based on subscription information of the target terminal. Optionally, the subscription information includes VoNR call cost for both the target terminal and the source terminal, as well as signal quality and other factors. The source terminal determines esims for the target terminal and the source terminal in the case where a plurality of esims are supported.

In addition, the terminal configures a setting whether to accept or reject the VoNR data call. The target terminal configures whether to receive the VoNR data call based on a plurality of connection parameters, such as communication link preferences or contact information preferences. In some cases, the target terminal receives a VoNR data call from the source terminal when certain communication links are available. In some embodiments, the target terminal receives a VoNR data call from a designated contact and otherwise rejects the VoNR data call. In some cases, the target terminal receives a VoNR data call based on an application for receiving the VoNR data call. For example, the target terminal receives a VoNR data call for a first application and deactivates the VoNR data call for a second application. The target terminal also receives a VoNR data call based on the current time or current location.

The 5G communication system comprises a cellular base station, a terminal and a core network. The 5G communication system supports enhanced broadband communication and ultra-reliable communication. The cellular base station communicates wirelessly with the terminals via a plurality of cellular base station antennas. Each cellular base station is associated with a particular geographic coverage area that supports communication with various terminals. The cellular base station provides communication coverage for various geographic coverage areas over communication links, and the communication links between the cellular base station and the terminals may utilize multiple carriers. The cellular base station is in bidirectional communication with the core network. For example, the cellular base station is connected to the core network by a no-load transmission link. The core network may provide user authentication, access authorization, tracking, IP connectivity, and other routing functions.

The 5G communication system includes a terminal a and a terminal B, which support wireless communication using a plurality of esims. For example, terminal a includes a first eSIM xa and a second eSIM yA. Terminal B can use the first eSIM xB and the second eSIM yB. Terminal a and terminal B selectively utilize any one of a plurality of esims when initiating a VoNR call. For example, when a VoNR call is initiated to terminal B, terminal a determines which eSIM to use based on a variety of factors such as channel quality, interference, coverage area, and the like.

Terminal a may also consider the information of terminal B when determining the eSIM for initiating the VoNR call to target terminal B. For example, terminal B uses the first eSIM xB to have better signal quality and the second eSIM yB to have poor signal quality. In this case, terminal B indicates within the subscription parameters that the VoNR call the first eSIM xB would generate poor call quality. Based on the received subscription parameters, terminal a calls the second eSIM yB of terminal B. Optionally, terminal a uses either its eSIM xA or yA when VoNR calls the second eSIM yB of terminal B. In some embodiments, terminal a also selects which eSIM to use when initiating a VoNR call based on the received subscription information.

The subscription information includes a plurality of subscription parameters related to a variety of information of the terminal B. Subscription information includes information related to call quality, signal strength, roaming, geographic location, use of data, cost of eSIM use, use of a processor, available communication links, contact information, or available software applications, etc. Terminal B selects which information to share with terminal a. For example, terminal B displays the subscription parameter option on the configuration interface, and the user of terminal B selects the shared subscription parameter through the configuration interface.

The terminals share subscription information over the wireless network, for example when exchanging contact information, or alternatively the terminals synchronize subscription information regularly, for example when initiating a VoNR call. For example, terminal a and terminal B exchange subscription information over a communication link. Terminal a requests subscription information from terminal B, and terminal B sends the subscription information in response. Optionally, the communication link is supported by a cellular base station. In some embodiments, the communication link is a direct connection between the terminals, or is formed by an access point or another intermediate network node for WiFi communication.

Terminal a receives subscription information and determines which eSIM to call VoNR and which eSIM to use based on the subscription information. Terminal a may also determine which eSIM to use based on a combination of its in-built subscription information and the subscription information of terminal B. Alternatively, the user of terminal a selects the eSIM based on the subscription information of terminal B. Optionally, the subscription information includes VoNR call cost and signal quality among other factors in terminal a and terminal B.

In some embodiments, terminal B may have poor signal quality for subscription services associated with the first eSIM xB but better signal quality for subscription services associated with the second eSIM yB. For example, the first eSIM xB is out of range of any cellular base station supporting the first subscription service, or terminal B is in an area with high interference for the first subscription service. Terminal B transmits to terminal a subscription parameter indicating a poor quality of the first eSIM xB or first subscription service. Accordingly, terminal a calls the second eSIM yB or a number associated with the second eSIM yB by the VoNR based on the received subscription information.

Optionally, terminal B roams over a subscription service associated with one of its esims, e.g., a second eSIM yB. Therefore, a VoNR call to the second eSIM yB may be costly for one or more of the subscribers. Terminal B indicates to terminal a that the second eSIM yB is roaming through the subscription information. Optionally, the subscription information includes a cost associated with the VoNR call roaming eSIM and a cost associated with the VoNR call any non-roaming eSIM. Terminal a selects which eSIM to call the VoNR based on the subscription information. For example, terminal a calls a first eSIM xB, avoiding the roaming charges of a VoNR call to a second eSIM yB.

Alternatively, the end B user may always prefer to use the second eSIM yB over the first eSIM xB. For example, a first eSIM yA is associated with a professional or work number, and terminal B indicates a preference to use a second eSIM yB to take a personal VoNR call, terminal B indicates the preference in the subscription parameters and transmits the subscription parameters to terminal a. Terminal a determines that VoNR will call the second eSIM yB when VoNR calls terminal a based on the indicated preferences in these subscription parameters.

In some embodiments, terminal B identifies the preferred eSIM for the particular user. For example, terminal B prefers to use a first eSIM xB for terminals associated with a first contact and a second eSIM yB for terminals associated with a second contact. Further, terminal B identifies a preferred eSIM for the contact group. For example, terminal B prefers to use a first eSIM xB for contacts associated with work and a second eSIM yB for contacts associated with friends or family. Terminal B indicates a preference in the subscription parameters to terminal a, and terminal a selects the eSIM to be VoNR called at terminal B based on the indicated preference.

Terminal B indicates to terminal a the subscription parameters including any number of combinations of settings. For example, terminal B includes eSIM information related to one or more of call quality, roaming, location, time, cost, user contacts, user contact groups, and personal preferences.

In addition, terminal B configures settings for receiving or rejecting or blocking a VoNR data call. For example, terminal B determines whether the user receiving the VoNR data call configures the settings through a configuration interface on terminal B based on a set of connection parameters such as communication link preferences or contact information preferences. For example, for a contact or application for which terminal B configures the option to receive a VoNR data call, there may be additional options in the setup options. For example, terminal B specifies a specific application, VoNR data call preferences of a specific user, or specifies preferences of a specific user when using a specific application.

Optionally, terminal B configures the VoNR data call setup based on the communication link availability. For example, terminal B turns off the VoNR data call reception when it is disconnected from the WiFi network. Optionally, terminal B indicates to terminal a set of connection parameters including a preference to reject the VoNR data call when disconnected from WiFi. Therefore, terminal a may not be able to make a VoNR data call to terminal B based on the connection parameters. For example, terminal a indicates to the user of terminal a to deactivate the VoNR data call with terminal B. The network protocol indicates whether terminal a makes a VoNR data call to terminal B over mobile data or WiFi. Terminal B also selectively configures the contact to accept or reject the VoNR data call based on the communication link availability. For example, upon disconnection from WiFi, terminal B accepts a VoNR data call from a first terminal associated with a first contact, but rejects a VoNR data call from a second terminal associated with a second contact.

Optionally, terminal B configures the VoNR data call setup for a specific application. For example, terminal B sets a preference for the first application to reject or block a VoNR data call and allows a VoNR data call for the second application. In some embodiments, terminal a allows a VoNR data call while connected to WiFi for the first application and allows or blocks a VoNR data call at any time for the second application. These preferences may be indicated to terminal a in the connection parameters and terminal a selects the application to make the VoNR data call based on the preferences.

Optionally, terminal B selects which contacts to make the VoNR data call. For example, terminal B selects whether contact information associated with the user of terminal a can make a VoNR data call to terminal B. Terminal B blocks terminal a from making a VoNR data call, terminal a receives an indication that a VoNR data call is not available. Optionally, terminal B selects the user of terminal a to make the VoNR data call when terminal B is connected to WiFi, rather than when terminal B is disconnected from WiFi.

Since the frequency band of 5G is much higher than that of 2G, 3G and 4G networks, the higher the frequency, the greater the attenuation in the signal propagation process, so the base station density of 5G networks will be higher. In order to effectively solve the network congestion situation in the point-to-point network transmission of a source terminal and a target terminal, the invention provides a cross-region multi-stage frequency band transmission architecture method, which comprises the steps of determining a basic frequency band for the transmission of a macro base station region; determining a first sub-band for propagation within a first micro base station region of the macro base station region; and determining a second sub-frequency band for propagation in a second micro base station region in the macro base station region, so that regional propagation information can be obtained in each region, and in addition, an idle frequency band which does not interfere with the existing frequency band can be used in each region, thereby achieving high-efficiency wireless propagation.

Firstly, a macro base station area RA is determined in space, and a full frequency band BA is selected to be used for propagation in the macro base station area RA. Then, a plurality of first micro base station regions RB are divided in the macro base station region RA, a first sub-band BB is selectively used in the first micro base station region RB, a plurality of second micro base station regions RC are divided in a region in the middle of the first micro base station region RB in the macro base station region RA, and a second sub-band BC is selectively used in the second micro base station regions RC. Through the staggered arrangement mode of the plurality of first micro base station regions RB and the plurality of second micro base station regions RC, the plurality of first micro base station regions RB can be mutually separated in space, and mutual interference is avoided.

In the area of the first micro base station area RB that is not overlapped with the second micro base station area RC, the third micro base station area RD is further divided, and the third sub-band BD is selected in the third micro base station area RD. As long as the frequency band does not spatially overlap with the second micro base station region RC or other third micro base station regions RD, and the mutual signals do not interfere with each other by spatial interleaving, the number of the third micro base station regions RD is plural, and the frequency band BC is used for propagation in the third micro base station region RD. Similarly, in a region of the second micro base station region RC that is not overlapped with the first micro base station region RB, the fourth micro base station region RE may be further divided, and the first sub-band BB is selected in the fourth micro base station region RE. As long as it does not spatially overlap with the first micro base station region RB or other fourth micro base station regions RE, and mutual signals do not interfere with each other by spatial interleaving, the fourth micro base station regions RE are plural and are simultaneously propagated in the fourth micro base station region RE using the first frequency sub-band BB.

Preferably, the transmitting base station T1 is located in the signal center of the second micro base station area RC, and has a receiver for receiving the first and third frequency sub-bands BB and BD and a transmitter for transmitting the second frequency sub-band BC, the transmitting base station T2 is located in the signal center of the third micro base station area RD, and has a receiver for receiving the first and second frequency sub-bands and a transmitter for transmitting the third frequency sub-band, and the transmitting base station T3 is located in the signal center of the fourth micro base station area RE, and has a receiver for receiving the second and third frequency sub-bands and a transmitter for transmitting the first frequency sub-band.

By the configuration of the transmitting base station, when the information transmitted in the first sub-band in the first micro base station region needs to be transmitted to the fourth micro base station region and transmitted, the receiver in the transmitting base station for receiving the first sub-band receives the information, and the transmitter arranged in the transmitting base station for transmitting the second sub-band transmits the information, at this time, the transmitter arranged in the transmitting base station for receiving the second sub-band transmits the information. In this way, the information can be extended from the first micro base station area into the range of the third micro base station area. Then, the next transmitting base station receives the information transmitted by the previous transmitting base station in the third sub-band and propagates in the fourth micro base station area in the first sub-band in a manner similar to that described above, and finally the destination transmitting base station receives the information transmitted in the first sub-band. Although the destination transmitting base station uses transmitters of the same frequency band, signals do not collide with each other by isolating the coverage area thereof through the transmission area.

Further, when a source terminal needs to perform communication with a plurality of target terminals, it is preferable that an NR frame for waking up a terminal is generated at the source terminal, the NR frame including a GUTI header and a check code sequence having an LRC, the check code sequence being determined based on a service group identification code associated with the source terminal; and outputting the NR frame for transmission to the plurality of target terminals.

Wherein generating and outputting the NR frame further comprises generating a bit string for the NR frame, the bit string comprising a first set of bits for the GUTI header and a second set of bits for a service group identification code associated with the source terminal, determining the check code sequence based on the first set of bits for the GUTI header and the second set of bits for the service group identification code, the check code sequence comprising a third set of bits, appending the third set of bits for the check code sequence to the bit string for the NR frame, and outputting the NR frame for transmission to the plurality of target terminals, the NR frame comprising the first set of bits for the GUTI header and the third set of bits for the check code sequence.

Wherein determining an LRC based on the GUTI header, determining the check code sequence based on the LRC and the service group identification code associated with the source terminal comprises generating the check code sequence by hashing the LRC and a portion of the service group identification code. Alternatively, the check code sequence may also be generated by xoring the LRC with a part of the service group identification code.

The header includes frame type information, address information and control information and a preamble signal including information for decoding a data unit, wherein the check code sequence is determined based on the frame type information, address information, control information and the service set identification code associated with the source terminal.

Determining whether the NR frame is for the source terminal based on comparing the check code sequence of the NR frame with a calculated check code sequence. Specifically, after determining an LRC based on the GUTI header of the NR frame and generating a check code sequence based on a stored service group identification code, determining whether the check code sequence of the NR frame matches a check code sequence by comparing the check code sequence of the NR frame with a check code sequence, determining that the NR frame is for the source terminal in response to determining that the check code sequence of the NR frame matches a check code sequence, and determining that the NR frame is not for the source terminal in response to determining that the check code sequence of the NR frame does not match a check code sequence.

Generating an NR frame not including a service group identification code inside reduces the size of the frame and the transmission management burden, and increases the transmission speed. Furthermore, hiding, hashing, scrambling or masking NR frames of the service group identification code in the check code sequence improves privacy and security.

The source terminal determines a frame type associated with the NR frame prior to initiating an operation to generate a check code sequence. The set of frame types for which the service group identification code is used to generate the check code sequence includes an NR beacon frame and an NR wakeup frame. If the source terminal determines that the frame type associated with the NR frame is an NR beacon frame or an NR wakeup frame, the source terminal determines a check code sequence using the service group identification code.

The source terminal operates in a multi-service group identification mode, the service group identification being a transmitted service group identification of the plurality of sets of multi-service group identifications when the service group identification associated with the source terminal is part of the plurality of sets of service group identifications of the source terminal. For example, the service group identification may be obtained from a hash of the service group identification associated with the source terminal.

Prior to generating the NR frame, the source terminal provides the service group identification code to the plurality of target terminals. A main NR unit of the source terminal transmits service group identities to a plurality of target terminals during the negotiation of the NR operating mode. The receiving device may use the service set identifier to confirm whether the received NR frame is intended for the receiving device.

Wherein the LRC is used to detect errors in unsecured messages. Prior to transmitting the message, the cellular base station logically combines the check code sequence with a portion or known sequence of the cellular base station's service set identification code. For example, the cellular base station may xor the check code sequence with the 2 least significant bits of the 3 most significant bits of the service set identification code of the cellular base station. Since the associated terminal has the service set identification code of the cellular base station, when the check code sequence is decoded by the receiving NR terminal, it is successfully decoded indicating that the NR terminal is receiving the message generated by the cellular base station of the NR terminal. Assuming that the service set identifier is present in the message, the cellular base station may calculate the LRC and may not transmit from the time of data transmission. When the receiver receives the message, the receiver checks the check code sequence assuming the presence of the service set identification code.

In summary, the invention provides a platform data optimization processing method based on the 5G communication technology, which selects esims of both parties with optimal call quality according to subscription parameters returned by an opposite end, thereby improving the quality and efficiency of the VoNR data call.

It will be apparent to those skilled in the art that the modules or steps of the present invention described above may be implemented in a general purpose computing system, centralized on a single computing system, or distributed across a network of computing systems, and optionally implemented in program code that is executable by the computing system, such that the program code is stored in a storage system and executed by the computing system.
