Users' demand for smartphones may no longer be limited to phone calls, such as data services such as games and videos. The demand for data services is also gradually increasing. Generally speaking, data services such as games and videos are delay-sensitive data services.

However, traditional smart phones supporting voice communication are generally set as the voice center by default, and the execution of voice services by the smart phone may cause the interruption of delay-sensitive data services, making users obviously perceive data service discontinuity, which affects user experience.

Detailed ways

The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

Radio access technology (RAT, radio access technology), is the basic physical connection method of radio-based communication networks, where RAT indicates the type of radio technology that the UE accesses to the core network (CN, core network), or indicates that the UE accesses the CN The type of radio technology. In mobile communication technology, different PLMNs can provide one or more different RAT access networks, so that communication devices in the mobile communication network that access the PLMN can use the RAT corresponding to the PLMN, such as the Global System for Mobile Communications ( GSM, global system for mobile communications technology, wideband code division multiple access (WCDMA) technology, long term evolution (LTE) technology, and future 5G new radio (NR, new radio) ) Technology, etc. In similar scenarios such as when the UE is powered on, disconnected from the network and reselected, or accesses the network after leaving the airplane mode, the UE needs to search for the network and attach, that is, perform network selection operations for PLMN and RAT.

As shown in Figure 1, the UE that requests to camp on the network side device or the UE that has camped on the network side device needs to interact with the network side device to adaptively configure what the UE and the network side device support The wireless access technology enables the UE to use the data communication service and/or voice communication service provided by the corresponding wireless access technology in the network side device. Specifically, the UE may include a mobile phone, a tablet computer, a PDA (Personal Digital Assistant), a POS (Point of Sales, sales terminal), a vehicle-mounted computer, etc. Here, the UE is a smart phone as an example. The data service Talking with a smart phone is the core business of a smart phone. Among them, for a multi-mode phone (supporting multiple access technologies), when the network side device supports multiple access technologies, the phone can reside on the network side device for use Multiple access technologies implement data communication services and/or voice communication services. Commonly, the mobile phone implements data communication services through the LTE technology provided by the network side equipment. When performing voice communication services, it uses circuit domain fallback (CSFB, circuit domain fallback). switched fallback) uses GSM technology to implement voice communication services, but in reality, with the development of social software and instant messaging software, more and more traditional voice needs are carried on ordinary data services, and users increasingly rely on According to the data service capabilities, in certain scenarios, such as games or videos, users often prefer to stay on the network corresponding to the wireless access technology that can stably provide data services, and can tolerate the voice communication services provided by CS, and even Do not want the traditional CS domain voice service to interrupt the data service (for example, CSFB interrupts the continuity of the data service or causes the data service to be unavailable). Generally speaking, it is believed that the GSM network has been unable to provide the packet switching (PS, packet switch) service capabilities that can meet the demand (for example, with strong real-time mobile games or online video playback), and WCDMA may provide usable services according to the difference of the protocol version. Service capability. When users have strong data service demands, they may reside on low-level access technologies such as GSM if they follow the general multi-mode network selection/reselection strategy.

As shown in Figure 2, during the specific network search process of the UE, in the suitable public land mobile network + radio access technology search (suitable PLMN+RAT search), the UE maintains some PLMN selection lists. These lists prioritize PLMNs. Sort by priority, and then search from high priority to the bottom. The priority from high to low is: attached public land mobile network + wireless access technology (RPLMN+RAT), home public land mobile network + wireless access technology (HPLMN+ RAT), user-controlled public land mobile network + wireless access technology (UPLMN+RAT), operator-controlled public land mobile network + wireless access technology (OPLMN+RAT), access to public land mobile network + wireless access technology (VPLMN+RAT), high-quality coverage random order (random order), low-quality coverage signal strength ranking, any public land mobile network search (anycell PLMN search), generally speaking, each type of PLMN in the list stores a corresponding One or more RATs, that is, identify one or more of GSM technology, WCDMA technology, LTE technology or NR technology. The UE traverses the PLMN selection list according to the priority order, and the UE can only camp on the PLMN corresponding to the RAT that matches the UE. It should be noted that the higher-priority PLMN in the figure does not necessarily have the coverage of advanced access technologies. That is, the PLMN selection order specified in the agreement may eventually reside on a low-level access technology of a high-priority PLMN. For example, consider a scenario where there are only Home PLMN or HPLMN GSM cells and operator OPLMN LTE cells in the environment. According to the network search sequence defined in the 3GPP protocol, a multi-mode terminal supporting LTE and GSM will eventually reside in The GSM cell of HPLMN cannot meet the data service requirements of users.

As shown in Figure 3, the UE can implement network communication through different wireless access technologies. Among them, the UE uses the base transceiver station (BTS, base transceiver station), base station controller (BSC, base station controller), and mobile station in the GSM technology. Network elements such as mobile switching center (MCS, mobile switching center) and serving GPRS support node (SGSN, serving GPRS support node) implement GSM technology network communication; UE implements WCDMA technology through the universal mobile communication system (UMTS, universal mobile telecommunications system) Node B (NodeB), radio network controller (RNC, radio network controller), SGSN and other network elements realize WCDMA technology network communication; UE through the evolved Node B (eNodeB, evolved Node B), mobility in LTE technology Management (MME, mobility management entity) functional entity, serving gateway (SGW, serving gateway) functional entity, packet data network service gateway (PGW, packet data network serving gateway) functional entity, Internet protocol (IP, internet protocol), etc. The network element realizes the network communication of LTE technology. When the UE is working based on the network architecture shown in Figure 2, for example, LTE only has data services registered successfully, and voice domain registration is rejected by the network. Reason #16 The mobile switching center is unreachable to the MSC. In this scenario, the LTE core network and the GSM/WCDMA core network are The interaction between the meta-MSC is abnormal, the user cannot complete the CS domain registration, the GSM/WCDMA paging message is unreachable to the user on LTE, and the user cannot complete the call. At this time, the voice domain preferences and UE usage are set to For the terminal of the voice center, the agreement stipulates that LTE needs to be prohibited and the network is available for voice. However, if the user is in a delay-sensitive data service, the search network will interrupt the service, which will reduce the experience. Similarly, the UE access 5G NR networks or more advanced radio access technologies in the future will also have similar problems, causing users to obviously feel that the data service is not continuous when using the UE, which makes the user experience lower. Specifically, the voice domain preferences and UE usage settings in the UE’s communication network settings have been set and fixed when the product leaves the factory. The voice domain preferences and UE usage settings include voice center identification. In order to support the voice communication of the UE, the UE carrying the voice center identification must reside on the PLMN corresponding to the RAT that supports voice communication. In this case, due to the wide coverage of the GSM network, the UE may reside on the GSM In the network, at this time, the user cannot use high-speed data communication in the GSM network. If the UE is performing a delay-sensitive data service, it will obviously perceive the service discontinuity, which will affect the user's experience.

In view of the network planning of different operators, some operators only have LTE cell coverage. For voice center terminals, if they reside in such cells and do not support higher-level IP multimedia subsystem (IMS, IP multimedia subsystem) voice communication services or IMS registration fails. According to the agreement, you cannot reside in the LTE cell. You need to search the GSM or WCDMA cell first. At this time, the processing stipulated in the agreement also does not meet the actual needs of the user; or, suppose that the user resides in a CSFB but not IMS In the cell, regardless of the terminal setting, the UE supports CS voice. If voice service occurs, CSFB will be sent to the GSM or WCDMA cell to complete the CS service. At this time, if the user is doing a delay-sensitive data service, he will obviously perceive the service. Discontinuity affects the user experience. To this end, the embodiments of the present application provide a wireless communication method and related equipment, which are used by a UE and a network-side device to adaptively configure the UE's preferred data communication service. The subsequent UE can use high-quality data communication services in the network-side device, and The data service indicated by the user preference information is allocated with priority to process the data service to improve the user experience.

As can be seen from the foregoing, the communication devices in the embodiments of the present application may include communication devices such as smart phones, tablet computers, PDAs, POS, and in-vehicle computers. In this embodiment, the communication devices include smart phones as an example for description. 4, when the communication device in the embodiment of the present application is implemented as a smart phone, in an implementation manner of the smart phone, the smart phone includes a universal serial bus (USB) in the hardware (Hardware) part. ) Interface, memory (Storage), non-volatile memory (NV, non-volatile memory), dynamic random access memory (DRAM, dynamic random access memory), register file (RF, register file); the smartphone is in use The processor (Application Processor) implements the user interface (User Interface), application (Application), radio interface layer (Radio Interface Layer), and implements LTE and NR non-independent networking (NSA, non-independent networking (NSA) in the Communication Processor). -standalone), GSM, WCDMA, LTE, NR independent networking and other networks; the UE is also connected to the network through the physical layer (Physical Layer), which includes the radio access network (Radio Access Network) , Core Network.

In the embodiments of this application, you can use These interfaces improve the settings of smart phones. After the settings are enabled, the behavior of each component of the Modem can be split into several functions that are independent of each other and can be flexibly combined.

In this embodiment, as an example, as shown in Figure 5-1, the UE can set a switch to adjust the UE's networking status on the UI, that is, select "Data Priority" in the "UE Networking Status" interface in the UI. Either "voice priority", or a switch can be set on the physical button of the UE to adjust the UE's networking status. In addition, the UE can respond to the user's response to the UE's networking status by recognizing the user's voice or other methods. Adjust instructions. Therefore, according to the user's adjustment of the UE's networking state, it is determined that the user preference information indicates that the data service is processed preferentially, so that the user can implement the UE to preferentially process the data service through the adjustment instruction to the UE's networking state, so that the UE can use high-quality data service communication .

(2) When the UE determines the user preference information, the user preference information can be determined by the instruction to start the application. When the UE starts the specified application according to the instruction to start the application, it is determined to give priority to processing data services. In this embodiment, exemplarily, as shown in Figure 5-2, there are multiple applications in the UE. Among them, the UE is more sensitive to delay when using certain applications to perform data communication services, such as video calls, Video playback or other applications that are sensitive to delay, or user-defined applications that require high-quality data communication, such as "online video", "game" and other applications in Figure 5-2, UE These applications can be set as designated applications, so that when the UE determines to start the designated application, the UE can determine that the user preference information is used to indicate priority processing of data services.

(3) When the UE determines the user preference information, the user preference information can be determined by the UE's data service requirements, that is, when the UE's data service requirements exceed the first threshold, it is determined to preferentially process the data service. In this embodiment, the UE can determine the data service requirements of its own operation, for example, it can be the download volume requirement in the download task, it can also be the download rate requirement in the download task, it can also be the cache requirement of video playback, etc. or other For the type of data service requirements, the UE can determine the first threshold through its own default settings or user operation instructions, and compare the data service requirements with the first threshold. When the data service requirements exceed the first threshold, determine the first threshold. User preference information is used to indicate the priority processing of data services. Exemplarily, take the data service requirement of the UE including the download volume requirement as an example. As shown in Figure 5-3, the UE may preset the first threshold to 2, 3 or other values, and the first threshold is set to a value of 2. As an example, when the UE determines that there are three download tasks "task one, task two, and task three" in the "download task", at this time, the UE judges that the current downloading demand is 3 greater than the first threshold 2. It is determined that the UE needs high-quality data communication services. At this time, it can be determined that the user preference information indicates that the data service is processed preferentially.

In addition, in addition to the above-mentioned ways to determine user preference information, user preference information can also be determined in other ways. User preference information can be determined in response to the user’s special marking of certain contacts in the address book. The UE can determine that the user has higher requirements for the voice communication service quality of these contacts. For example, as shown in Figure 5-4, the "leader" in the address book has a special mark set by the user, while "colleague A", "Friend A" and "Friend B" do not have special flags set by the user, that is, the UE can determine that when the UE is in a voice call with the "leader", the UE can determine to give priority to the voice service; or it can pass the user's It is determined in the memo that the voice communication service is required for a specified period of time. Therefore, it can be determined that the UE needs a higher-quality voice communication service during this period of time, so that it can be determined that the user preference information indicates that the voice service should be processed first. The user preference information is determined in other ways, which is not limited here.

502. The UE sends an initial registration message to the network side device.

In this embodiment, the UE sends an initial registration message to the network side device. The initial registration message includes a user equipment UE usage setting information element, or the initial registration message may further include a voice domain preference information element, which is determined in step 501 The user preference information of is used to indicate that when the data service is processed preferentially, the usage setting information element of the UE carries the data center identifier.

Wherein, the initial registration message also includes a voice domain preference information element. When the user preference information is used to indicate priority processing of data services, the voice domain preference information element carries only the IMS PS voice identifier, and the voice domain preference information For details about the usage setting information element of the element and the UE, please refer to the description in the 3GPP protocol TS 24.008 10.5.5.28. In addition, the voice domain preference cell can specifically carry the Internet multimedia subsystem packet-switched IMS PS voice only (IMS PS Voice only), circuit-switched CS voice only (CS Voice only) identity, and the preferred CS voice second Internet multimedia Subsystem packet-switched IMS PS voice (CS voice preferred, IMS PS Voice as secondary) identification or preferred IMS PS voice secondary selection CS voice (IMS PS voice preferred, CS Voice as secondary) identification, when the user preference information is used to indicate When the data service is processed preferentially, the voice domain preference cell is updated to carry only the IMS PS voice identifier. Therefore, when the user preference information is used to indicate priority processing of data services, it indicates that the UE prefers data communication services. At this time, the voice domain preference information element can be updated to carry only the IMS PS voice identifier, so that the UE can Use the IMS voice communication service to avoid the discontinuity of the data service currently performed by the UE caused by switching to the CS voice, and further improve the user experience.

In this embodiment, specifically during the execution of step 502, different processes of sending initial registration messages to the network side device can be implemented according to different current connection states of the UE, which will be described in specific embodiments below.

1. When the UE has attached to the LTE network cell;

In this embodiment, when the UE is attached to the network side device and the network side device includes a Long Term Evolution LTE network cell, sending an initial registration message to the network side device includes: sending a tracking area update TAU request to the network side device Message, wherein, the TAU request message includes a usage setting information element of the UE, or the TAU request message may further include a voice domain preference information element. That is, when the UE has attached to the LTE network cell, the UE can adaptively configure the UE preference data communication with the network side device through the TAU request message carrying the voice domain preference information element and the UE usage setting information element. service.

Among them, the implementation process of the UE sending a TAU request (TRACKING AREA UPDATE REQUEST) message to an attached LTE network cell can refer to the relevant description of TS 24.301 8.2.29 in the 3GPP protocol.

In addition, referring to TS36.331 in the protocol for cell reselection, when the UE is attached to an LTE network cell, cell reselection is required. Generally, the cell reselection does not evaluate the service capabilities of the target cell. Therefore, it may be reselected to a cell with better energy but smaller bandwidth or lower-level access technology. Furthermore, considering that even if the UE can camp on an LTE network cell, an LTE network cell carrying users close to the upper limit of capacity, the actual service performance (using data service delay and rate as indicators) is likely to be worse than that of the WCDMA cell, in extreme cases It may even be worse than the GSM cell. In addition, staying at the edge of the LTE network may provide poorer service quality than the WCDMA network. Although the network side equipment will have some redirection mechanisms to migrate the terminal to other cells/ In terms of access technology, it is still unavoidable for users to gather access in high-level access technology cells. This scenario is a bad (bad) cell with high-priority access technology. This is for UEs attached to LTE network cells to access this. For this cell, the solution can be further optimized, that is, the service quality of the relevant LTE network cell is detected. The following will introduce the relevant detection process through several aspects of implementation.

(1) Detecting LTE cell bandwidth information-when the UE has attached to an LTE network cell, the method also includes: receiving a Master Information Block (Master Information Block) message from the LTE network cell, the MIB message including LTE cell bandwidth information ; When the LTE cell bandwidth information is lower than the second threshold, in the process of performing cell reselection, reduce the reselection priority of the LTE network cell.

Among them, the implementation process of the MIB message can refer to the content described in TS 36.331 6.2.2 in the 3GPP protocol. In the process described in this section of the protocol, the UE can obtain the information through the master information block field descriptions. Resource blocks (RB, resource blocks), where the number of RBs strictly corresponds to the bandwidth (for example, 1.4M, 3M, 5M, 10M, 15M, 20M). Thereafter, the UE can pass the preset second threshold or respond to the user Operate the second threshold determined by the instruction to make a judgment. For example, the second threshold is preset to 5M. Thereafter, the judgment can be made according to the number of RBs in the MIB message. If the LTE cell bandwidth information is lower than the second threshold, the In the process of performing cell reselection, the reselection priority of the LTE network cell is lowered.

In this embodiment, the UE can determine the LTE cell bandwidth information according to the MIB message from the LTE network cell, and further determine that when the LTE cell bandwidth information is lower than the second threshold, in the process of performing cell reselection, reduce The reselection priority of the LTE network cell can even initiate a detach process, so as to prevent the UE from camping on a poor cell of the LTE technology. After that, the UE enters an idle state.

(2) Detect whether the LTE cell supports NSA--when the UE has attached to the LTE network cell, the method also includes: receiving a System Information (System Information) message from the LTE network cell, and the system message information includes the system information type Block (SystemInformationBlockType2), the fields in the system information type block: UpperLayerIndication is used to indicate whether the LTE network cell supports non-independent networking NSA; when the system information type block indicates that the LTE network cell supports NSA, Improve the reselection priority of the LTE network cell.

Among them, the implementation process of the System Information (System Information) message can refer to the TS36331 R15 and later versions of the 3GPP protocol. For example, in the content described in TS36.331 5.2.2.9, in the process described in this section of the protocol, Specifically, you can use the field "Note: upperLayerIndication is an indication to the upper layer, indicating that the UE has entered the coverage area that provides 5G functions. (NOTE: upperLayerIndication is an indication to upper layers that the UE has entered a coverage area that offers 5G capabilities.)" To determine whether the LTE cell supports NSA. After that, the UE determines that it can establish a dual connection with the NR network cell through the LTE network cell, that is, determines that the LTE network cell can provide high-quality communication services. For cells that support NR capabilities, the serving cell evaluation criteria need to consider the current LTE cell Whether to support dual link, the priority of a cell that supports NSA needs to be increased (even if its LTE bandwidth is small), so that the reselection priority of the LTE network cell can be increased when the UE performs cell reselection.

(3) Detect EPS QOS of LTE cell--

When the UE is attached to the LTE network cell, the method further includes: the UE receives an activation dedicated EPS bearer context request (ACTIVATE DEDICATED EPS BEARER CONTEXT REQUEST) message from the LTE network cell, and the activation dedicated EPS bearer context request The message includes EPS QOS (EPS quality of service) information about the quality of service of the evolved packet system; when the EPS QOS is lower than the third threshold, the cell reselection priority of the LTE network is lowered during the cell reselection process.

Among them, the UE can determine the EPS QOS of the LTE cell by activating the dedicated EPS bearer context request (ACTIVATE DEDICATED EPS BEARER CONTEXT REQUEST) message. The implementation process of the EPS QOS can refer to TS35.TS24301 9.9.4.3 in the 3GPP protocol for details. In other words, the field in EPS QOS can be used "If the sending entity wants to indicate the maximum bit rate of the downlink higher than 8640kbps, then octet 5 should be set to "11111110", that is, 8640kbps, and it should be in the octet. The value of the maximum bit rate encoded in 9 (If the sending entity wants to indicate a maximum bit rate for downlink higher than 8640 kbps, it shall set octet 5 to "11111110", ie8640 kbps, and shall encode the maximum value for the rate octet 9)”, when the downlink indicated by the network in this field is not the maximum bit rate (that is, the third threshold), the UE determines that the LTE network cell has a restriction, that is, the EPS QOS of the LTE network cell is not the most Excellent, it is necessary to reduce the reselection priority of the LTE network cell during the cell reselection process, so that it can be reselected to a cell with better service quality through the cell reselection.

Similarly, in addition to obtaining the EPS QOS by activating the dedicated EPS bearer context request (ACTIVATE DEDICATED EPS BEARER CONTEXT REQUEST) message, the UE can also activate the default EPS bearer context request (ACTIVATE DEFAULT EPS BEARER CONTEXT REQUEST) Messages, MODIFY EPS BEARER CONTEXT REQUEST (Modify Evolved Packet System EPS Bearer CONTEXT REQUEST) messages or other messages are used to obtain the EPS QOS. From now on, the EPS QOS judgment process can refer to the above content, which will not be repeated here.

2. When the UE has attached to the NR network cell;

In this embodiment, when the UE has been attached to the network-side device and the network-side device includes a long-term evolution NR network cell, in the foregoing steps, the UE sending an initial registration message to the network-side device includes: the UE sends to the NR network cell A registration request (REGISTRATION REQUEST) message, where the registration request message includes the usage setting information element of the UE. That is to say, when the UE has attached to the NR network cell, it is assumed that the NR network cell can provide high-quality data communication services. Therefore, the UE can communicate with the network side through the registration request message carrying the UE's usage setting information element. The device adaptively configures the UE to prefer data communication services.

Among them, the process of the UE sending a registration request (REGISTRATION REQUEST) message to the network side device can refer to the description of TS 25.401 8.2.6 in the 3GPP protocol.

3. When the UE has attached to the WCDMA network cell;

In this embodiment, when the UE is attached to the network-side device and the network-side device includes a WCDMA network cell, in the foregoing steps, the UE sending an initial registration message to the network-side device includes: the UE sends a routing area to the WCDMA network cell An update request (ROUTING AREA UPDATE REQUEST) message. The routing area update request message includes the voice domain preference information element and the UE usage setting information element. That is to say, when the UE has attached to the WCDMA network cell, the UE can adapt the UE preference to the network side device through the routing area update request message carrying the voice domain preference information element and the UE usage setting information element. Data communication services.

Among them, the process of the UE sending a routing area update request (ROUTING AREA UPDATE REQUEST) message to the network side device can refer to the description of TS 24.008 9.4.14 in the 3GPP protocol.

4. When the UE has attached to a GSM network cell;

In this embodiment, when the UE has been attached to the network-side device and the network-side device includes a GSM network cell, the initial registration message sent by the UE to the network-side device in the foregoing steps is no longer performed, because the GSM network cell cannot provide high-level information by default. Quality data communication services, therefore, it is necessary to initiate a detachment process to the GSM network cell.

In the embodiment of this application, based on the embodiment described in FIG. 5, specifically in the process of determining user preference information in step 501, when the user preference information is used to indicate priority processing of data services, since the GSM network cell defaults to fail to provide high-quality Data communication services, and the quality of data communication services that WCDMA can provide has gradually been unable to meet the needs of users for high-speed data communication. Therefore, the solution can be further optimized, which will be further described in conjunction with the flow chart below.

Referring to FIG. 6, based on the embodiment described in FIG. 5, an embodiment of a wireless communication method in the embodiment of the present application for the user determined in step 501 includes:

601. The UE receives a UE capability query request message from a network side device.

Specifically, the network access capabilities supported by the UE generally include the provision of low-quality data services WCDMA technology and/or GSM technology. Therefore, after receiving the UE capability query request message from the network side device, the user preference information is used to indicate When the data service is processed preferentially, the UE capability information message of the UE is updated, and the UE capability information message indicates that the UE does not support WCDMA and/or does not support GSM.

Among them, the process of the UE receiving the UE CapabilityEnquiry message sent by the network-side device can refer to the description of TS36.331 5.6.3 in the 3GPP protocol.

602. The UE sends a UE capability information message to the network side device.

The UE capability information The message indicates that the UE does not support WCDMA and/or does not support GSM.

Specifically, the supported network access capabilities generally include UE capability information corresponding to UEs that provide low-quality data services WCDMA technology and/or GSM technology, including information about the frequency band that the UE supports communication, and the network side device can pass this frequency band. The information determines that the UE supports WCDMA technology and/or GSM technology. Therefore, the UE capability information can be updated so that the frequency band information supported by the UE capability information does not include the frequency band corresponding to WCDMA technology and/or GSM technology. The UE capability information message enables the network side device to adaptively configure the UE's preferred data communication service, so that the network side knows that the UE does not support WCDMA and/or does not support GSM, and prevents the network side device from initiating a redirection to direct the UE to WCDMA and/or The cell corresponding to the GSM technology camps on, causing the interruption or discontinuity of the data communication service performed by the UE.

Among them, the process of the UE receiving the UE Capability Information (UECapabilityInformation) message sent by the network-side device can refer to the description of TS36.331 5.6.3 in the 3GPP protocol.
