[0022] The technical solutions of the present application can be applied to various communication systems, such as long term evolution (LTE) system, worldwide interoperability for microwave access (WiMAX) communication system, 5th generation (5G) system, such as new radio access technology (NR), and future communication system, such as 6th generation (6G) system, etc.

[0023] The technical solutions provided by the present application can be applied to a heterogeneous communication network, that is, the network supported by the terminal in the embodiments of the present application can be a network in which multiple radio access technologies exist simultaneously, for example, a wireless fidelity (WiFi) network and a long term evolution (LTE) network exist simultaneously.

[0024] For the purposes of the present application, the term "coupled" is used to describe both an indirect

[0025] In the present application, the word "exemplary" or "for example" is used to illustrate, exemplify, or describe a specific embodiment or implementation. Any embodiment or implementation described as "exemplary" or "for example" in the present application should not be construed as being more preferred or advantageous than other embodiments or implementations. Rather, use of the word "exemplary" or "for example" is intended to present concepts in a concrete manner.

[0026] In some scenarios, the present application is described in the context of LTE and WiFi networks in a wireless communication network. It should be noted that the present application can also be applied to other wireless communication networks, and the corresponding names can also be replaced by the corresponding names of the functions in other wireless communication networks.

[0027] To facilitate understanding of the present application, first take the communication system shown in Figure 1 as an example to describe in detail the communication system applicable to the present application. Figure 1 The communication system shown in FIG. 1 is applicable to the present application. As shown in Figure 1 the communication system 100 includes a network device 102 and a terminal 106, the network device 102 can be configured with one or more antennas, and the terminal can also be configured with one or more antennas. Optionally, the communication system can also include a network device 104, which can also be configured with multiple antennas.

[0028] It should be understood that the network device 102 or the network device 104 can also include a plurality of components (e.g., a processor, a modulator, a multiplexer, a demodulator, or a demultiplexer, etc.) related to signal transmission and reception.

[0029] The network device is a device with wireless transceiving function or a chip that can be arranged in the device. The device includes, but is not limited to, an evolved Node B (eNB), a radio network controller (RNC), a Node B (NB), a base station controller (BSC), a base transceiver station (BTS), a home base station (e.g., a home eNB or a home NB, HNB), a baseband unit (BBU), an access point (AP) in a wireless fidelity (WIFI) system, a wireless relay node, a wireless backhaul node, a transmission and reception point (TRP or TP), etc. The network device can also be a gNB or a TP in a 5G (e.g., a NR) system, one or a group of (including multiple antenna panels) antenna panels of a base station in a 5G system, or a network node (e.g., a BBU or a distributed unit (DU)) constituting a gNB or a TP.

[0030] In some deployments, a gNB can include a centralized unit (CU) and a DU. The gNB can also include a radio unit (RU). The CU implements part of the functionality of the gNB and the DU implements part of the functionality of the gNB, for example, the CU implements the radio resource control (RRC) and packet data convergence protocol (PDCP) layers, and the DU implements the radio link control (RLC), media access control (MAC), and physical (PHY) layers. Since the information at the RRC layer eventually becomes, or is translated into, information at the PHY layer, high layer signaling, such as RRC layer signaling or PDCP layer signaling, can also be considered as being transmitted by the DU, or by the DU+RU, under this architecture. It can be understood that a network device can be a CU node, or a DU node, or a device including a CU node and a DU node. In addition, the CU can be divided into a network device in an access network RAN, or the CU can be divided into a network device in a core network CN, which is not limited here.

[0031] The terminal 106 can also be referred to as a user equipment (UE), an access terminal, a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, or a user device. The terminal in the embodiments of the present application can be a mobile phone, a Pad, a smart printer, a train detector, a gas station detector, a computer with wireless transceiver function, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self driving, a wireless terminal in remote medical treatment, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, and the like. The embodiments of the present application do not limit the application scenarios. The terminal 106 and the chip that can be arranged in the terminal 106 in the present application are collectively referred to as a terminal.

[0032] Both network device 102 and network device 104 can communicate with multiple terminals (such as terminal 106 shown in the figure). Network device 102 and network device 104 can communicate with any number of terminals similar to terminal 106. However, it should be understood that the terminal communicating with network device 102 and the terminal communicating with network device 104 can be the same or different. Figure 1 The terminal 106 shown can communicate with both network device 102 and network device 104 simultaneously, but this only shows one possible scenario. In some scenarios, the terminal may only communicate with network device 102 or network device 104, and the present invention does not limit this.

[0033] It should be understood that Figure 1 This is a simplified illustration for ease of understanding only. The communication system may also include other network devices or other terminals. Figure 1 It was not drawn in the middle.

[0034] To ensure compatibility with software versions in heterogeneous networks and enable seamless switching between WiFi and LTE software versions, this invention provides a method for achieving software version compatibility in heterogeneous networks. This method can be executed by a terminal. In the following embodiments of this invention, the terminal can be... Figure 1 The terminal 106 shown below, the network device in the following content can be Figure 1 The network device 102 shown is illustrated. It should be understood that in this invention, the steps executed by the terminal can also be specifically executed by a module or component of the terminal, such as a chip within the terminal. The following embodiments are described with the terminal as the executing entity. Figure 2 The flowchart illustrates a software version compatibility method for heterogeneous networks provided by an embodiment of the present invention. The method includes:

[0035] S201, Read the terminal's hardware attributes;

[0036] S202, when it is determined from the hardware attributes that the current mode of the terminal is WiFi-only, stop loading and start the modem service; when it is determined from the hardware attributes that the current mode of the terminal is LTE-supported, load and start the modem service.

[0037] The hardware attribute in the embodiment can refer to general-purpose input / output (GPIO) and chip identification (chipid) of the hardware. Since the gpio, chipid and the like are different in different software versions, the hardware attribute is read by using a system command line (cmdline) to realize adaptive software version switching, i.e., the Modem control service needs to be judged by analyzing the cmdline to determine whether to load and start the Modem. It can be seen that the terminal system can realize dynamic loading of the modem service according to the hardware attribute, and realize free switching of the WiFi software version and the LTE software version.

[0038] The process of loading and starting the modem service in the embodiment mainly refers to: initializing the structure related to the modem service, carrying the code related to the modem service or other subsystems to the specified area, releasing the register related to controlling the modem to run after the carrying operation is completed, and finally starting the modem service successfully. It can be seen that when the current mode of the terminal is only the WiFi mode, the modem-related structure is not initialized, such as Removeinitcploadinfo, the modem-related code is not carried (such as Removecploadinfoimg), the register related to controlling the modem to run is not released, the task of monitoring the modem is not created (such as Removelistenmodemtask), and the message of modem alive is not transmitted to the clients (such as Removewait modemalive).

[0039] In a possible implementation, the Modem-related device node is adaptively deleted according to the hardware attribute when the current mode of the terminal is only the WiFi mode, as shown in the example of Figure 3 When the terminal system is started, it is firstly judged whether the current mode of the terminal is only the WiFi mode. If yes, the device nodes of the LTE network are removed, such as stty_lte / sdiag_lte / spipe_lte / sipc_lte / spool and the like. Otherwise, the process of dynamically loading the modem service is completed and then the process is ended.

[0040] The terminal system in the embodiment can dynamically load the modem according to the properties of different hardware, realize adaptive switching between WiFi only and LTE version, and realize that the modem is cut in software form when the current mode is only the WiFi mode. It should be understood that, due to the starting of the modem, the sp, the dp and the like, the monitoring and the like are all controlled and guided by the modem, in order to realize shielding of the modem and without affecting the starting of the sp, the dp and the like, the control of the modem cannot be completely shielded. Since the WiFi software version stops the service of the modem, the device nodes related to the modem still exist, although they will not affect the stopping of the service of the modem, they will still send related instructions and occupy the memory, therefore, deleting the device nodes related to the modem can further realize optimization of the WiFi software version.

[0041] The same as the concept of the above embodiment, the embodiment of the application further provides a software version compatible device of a heterogeneous network. The device 400 is used to realize the function of the terminal in the above method. The device 400 can be a terminal or a device in the terminal. The device can be a chip system.

[0042] In an example, as shown in Figure 4 The device 400 includes a reading module 401 configured to read the hardware properties of the terminal, and a processing module 402 configured to stop loading and starting the modem service when it is determined according to the hardware properties that the current mode of the terminal is only the WiFi mode, and load and start the modem service when it is determined according to the hardware properties that the current mode of the terminal is the LTE mode.

[0043] The division of the modules in the embodiment of the application is illustrative, and is only a logical function division. In actual implementation, there can be another division mode. In addition, the function modules in each embodiment of the application can be integrated in one processor, or can be physically separated, or two or more modules can be integrated in one module. The integrated module can be realized in the form of hardware or in the form of a software function module.

[0044] In another example, as shown in Figure 5As shown, the communication apparatus 500 includes at least one processor 510 and a memory 520. The memory 520 stores a computer program. The memory 520 and the processor 510 are coupled. The communication apparatus 500 can refer to the terminal as described above.

As another implementation, the memory 520 can also be located outside the communication apparatus 500. The processor 510 can operate in cooperation with the memory 520. The processor 510 can invoke the computer program stored in the memory 520. At least one of the at least one memory can be included in the processor.

[0045] In some embodiments, the communication apparatus 500 can further include a communication interface 530 for communicating with other devices through a transmission medium, so that the devices in the communication apparatus 500 can communicate with other devices. For example, the communication interface 530 can be a transceiver, a circuit, a bus, a module or other types of communication interfaces, and the other devices can be other terminals. The processor 510 transceives information by using the communication interface 530, and is used to implement the method in the above embodiments.
