Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terms "first," "second," "third," and "fourth," if any, in the description and claims of the invention and in the above-described figures are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
The data processing method provided by the embodiment of the invention can be applied to an application scene that the terminal equipment receives the data sent by the network equipment through the non-cellular mobile communication network. The terminal device may be a wireless terminal device that receives the network device scheduling and indication information, and may be, for example, a mobile phone, a computer, a data card, or the like. The network device is a device for communicating with the mobile device, and may be, for example, a base station (NodeB) or the like, and the network device may include only a Wi-Fi network device, may also include a Wi-Fi network device and a network device of a cellular mobile communication network, may also include a Wi-Fi network device and a network device of an IMS network, and may also include a Wi-Fi network device, a network device of a cellular mobile communication network, and a network device of an IMS network. The cellular mobile communication network may be a cellular mobile communication network defined by a 3rd Generation Partnership Project (3 GPP) specification, and the non-cellular mobile communication network may be other networks, such as a Wi-Fi network or an ethernet network, except for cellular mobile communication networks defined by the 3GPP specification, such as a 3rd Generation Partnership Project (3rd Generation, 3G), a fourth Generation mobile communication technology (4th Generation, 4G), a fifth Generation cellular mobile communication (5th Generation Wireless Systems, 5G), and a sixth Generation mobile communication technology (6th Generation, 6G).
With the evolution of communication protocols, the relationship between Wi-Fi and mobile communication is more and more compact, and as an access mode, terminal equipment can access a cellular mobile communication network through Wi-Fi. For example, VoWi-Fi is communicated by a terminal device through Wi-Fi and a non-cellular mobile communication network, and multimedia functions such as voice, video, and the like based on IP multimedia are provided through an IMS of the terminal device and an IMS of a network device, and other functions such as Short Message Service (SMS). The 5G NAS messages may also communicate over Wi-Fi and a non-cellular mobile communications Network Core Network (CN). Wi-Fi is an access technology of a terminal, and 3GPP conventional access technologies, such as 2G, 3G, 4G or 5G, are also becoming more and more compact, for example, due to changes in radio conditions, which require inter-switching between Wi-Fi and these 3GPP access technologies.
Fig. 1 is a schematic diagram of a system architecture for a terminal device to send data in the prior art, as shown in fig. 1, an AP in the prior art includes an IP-based Multimedia Subsystem (IMS), a video engine (video engine), and a TCP/IP module. The IMS in the AP is configured to process a Session Initiation Protocol (SIP) signaling, the video engine (video engine) is configured to generate or process video data, and the TCP/IP module in the AP and the TCP/IP module in the CP are configured to send data according to the TCP/IP Protocol.
In addition, the AP also comprises a Wi-Fi (Wireless-Fidelity) based application module, which comprises a Wi-Fi driving module, a Wi-Fi management module, a Wi-Fi service module, a Wi-Fi safety module and other functional modules, wherein the Wi-Fi driving module is used for controlling communication between the terminal equipment and the Wi-Fi, and comprises loading, starting, inter-core control and data interaction channel maintenance and control of the AP on the Wi-Fi, abnormal processing when a fault occurs and the like.
The Wi-Fi management module is used for monitoring Wi-Fi hotspots and signal strength, selecting different Wi-Fi hotspots or switching among the Wi-Fi hotspots according to network or terminal equipment definition and the like.
The Wi-Fi service module is used for being responsible for control of Wi-Fi link establishment, maintenance, release and the like according to different applications, and comprises the steps of establishing corresponding security link, maintenance and the like, for example, when the Wi-Fi access to the IMS network is performed, one access mode (for example, a non-trusted Wi-Fi hotspot and a S2b mode is selected) from multiple modes (for example, S2a, S2b, S2c and the like) of accessing the IMS network is performed according to network indication or terminal configuration.
The Wi-Fi security module is used for realizing security protection of Wi-Fi links, and different applications may correspond to different security policies and security level requirements.
The CP includes command and control modules (command and control), IMS and TCP/IP modules. The command and control module in the CP is used for controlling communication between the AP and the CP, the IMS includes an SIP processing module and an audio engine (voice engine), the SIP processing module is used for generating and processing SIP signaling, and the audio engine (voice engine) is used for generating or processing audio data. In addition, the CP may communicate data with a cellular mobile communication network, which may be, for example, a 3G, 4G, 5G, or 6G network, via a radio access technology defined by the 3rd Generation Partnership Project (3 GPP) specification.
As can be seen from fig. 1, currently, the signaling related to the terminal device and the communication is mainly processed in the CP, and the voice data for the non-cellular mobile communication network is also mainly processed in the CP. If the Wi-Fi is used as a terminal device access technology to communicate with a network, the Wi-Fi processor of the terminal device can only directly communicate with the AP, and all signaling and data of the CP can only be forwarded through the AP. That is, since the Wi-Fi is linked to the AP, when the terminal device receives data sent by the network device through the Wi-Fi network, the AP of the terminal device needs to forward data processed by the CP to the CP through a path between the AP and the CP when receiving data through the Wi-Fi network. When receiving data, the AP needs to be woken up, and the AP receives the data sent by the network device and forwards the data to the CP.
The prior art solution based on fig. 1 is for several reasons: 1. the AP chip and the Wi-Fi chip relate to cross-core control and communication, relate to a complete set of complicated control and management, include loading, starting, route design of communication among the cores, state detection and control of the link and non-link state of the starting stage/link of the AP processor to Wi-Fi, unusual treatment when breaking down, control such as linking, switching, etc., tools and schemes such as maintaining and debugging, etc., there has been a set of perfect control, management and interaction schemes in the existing Operating System (OS) (for example, Android, etc.), through the use, debugging and continuous upgrade and optimization of the Operating System for many years of the terminal equipment industry, the framework and scheme between AP and Wi-Fi processor have been relatively stable.
2. The Wi-Fi-based application is mainly related to the AP, such as internet surfing, entertainment, file uploading and downloading and the like, the application does not need the participation of the CP, the AP and the Wi-Fi chip can be completed as a whole with a complete function, and for example, the AP and the Wi-Fi chip in various Pad terminals can be completed as a whole with functions of internet surfing, entertainment, file uploading and downloading and the like.
3. Because the communication, maintenance and technology between the CP and the AP and between the Wi-Fi and the AP are relatively mature and stable technologies, if the CP needs to communicate with the network through the Wi-Fi, the AP adopts the architecture based on the figure 1, and after receiving the data sent by the Wi-Fi processor, the AP forwards the data to the CP, so that the method is technically easier to realize and maintain.
4. The complexity of inter-core communication is multiplied if the communication between Wi-Fi and CP is increased. The CP/AP/Wi-Fi cross-core processing, control and maintenance between each other are more complex and difficult to realize than the traditional Wi-Fi and CP chips which only respectively control and communicate with the AP chip.
However, the technical implementation as shown in fig. 1 has the following problems: 1. it is not beneficial to reduce the power consumption of the mobile terminal. Based on the existing Wi-Fi communication scheme, when receiving signaling or data processed by the CP, the AP needs to forward the signaling or data to the CP, and the forwarding wakes up the AP, thereby increasing power consumption of the terminal device. Meanwhile, the efficiency of forwarding through the AP is relatively low. 2. With the evolution of communication protocols, Wi-Fi-based communication is no longer limited to applications such as the traditional hypertext Transfer Protocol (HTTP), File Transfer Protocol (FTP), and the like. The 3GPP specifications use Wi-Fi as an access technology for the terminal device to communicate with the cellular mobile communication network, for example: 1) the Vowi-Fi is communicated with a non-cellular mobile communication network through the Wi-Fi by a terminal, and multimedia functions of voice, video and the like based on IP multimedia and other functions of Short Message Service (SMS) and the like are provided through an IMS of a terminal device and an IMS of a network device. 2) The 5G NAS messages may also communicate over Wi-Fi and a non-cellular mobile communications Network Core Network (CN). 3) Wi-Fi, an access technology of a terminal device, is more and more closely related to 3GPP legacy access technologies, such as 2G, 3G, 4G or 5G, and Wi-Fi and these 3GPP access technologies may be switched with each other due to, for example, a change in radio conditions. Wi-Fi can not directly communicate with the CP if only accessing the AP, which is not beneficial to the timely interaction between Wi-Fi and other access technologies defined by 3 GPP.
In view of the above problems, the embodiment of the present invention provides a data processing method, as shown in fig. 2. Fig. 2 is a schematic diagram of a possible system architecture according to an embodiment of the present invention, in which, in addition to directly communicating with the AP of the terminal, supporting legacy applications, the chip/device of Wi-Fi or other non-cellular mobile communication (e.g., ethernet) access technology also communicates directly with the CP of the terminal device, i.e., Wi-Fi or other non-cellular mobile communication access technology, is linked to the CP of the terminal device, in this way, if the data processed by the CP needs to be received by the chip/device of Wi-Fi or other non-cellular mobile communication access technology, the CP may directly receive the data sent by the network device through the non-cellular mobile communication network, the CP may directly process the data, or the CP may transmit the data to the AP of the terminal device to cause the AP to process the data. Wi-Fi is used as an example for simplicity, but the techniques and embodiments of the method are equally applicable to other non-cellular mobile communication technologies.
In fig. 2, a video engine (video engine) and a TCP/IP module included in the AP are similar to those in fig. 1, the video engine (video engine) in the AP is used to generate or process video data, and the TCP/IP module in the AP and the TCP/IP module in the CP are used to transmit data according to a TCP/IP protocol. In addition, traditional internet surfing, entertainment, file uploading and downloading and other signaling and data are communicated through a direct link between the AP and the Wi-Fi. The AP still comprises Wi-Fi-based application modules, including functional modules such as a Wi-Fi driving module, a Wi-Fi management module, a Wi-Fi service module and a Wi-Fi safety module.
Similar to fig. 1, the command and control module in the CP is used to control communication between the AP and the CP, the IMS includes an SIP processing module and an audio engine (voice engine), the SIP processing module is used to generate and process SIP signaling, the audio engine (voice engine) is used to generate or process audio data, and the service routing module is used to receive data through the non-cellular mobile communication network or the cellular mobile communication network and route the received data to the AP. In addition, the CP may perform data communication with a cellular mobile communication network, which may be, for example, a 3G, 4G, 5G, or 6G network, through a radio access technology defined by 3 GPP.
Furthermore, in order to support the direct communication between the CP and the Wi-Fi, a CP Wi-Fi driving module, a CP Wi-Fi management module, a functional module supporting CP service management (for example, IMS service), CP Wi-Fi security management, and the like need to be added to the CP. The functional modules of the CP Wi-Fi driving module, the CP Wi-Fi management module and the like are similar to those in the figure 1 and are used for supporting the CP business management module to only process the business related to the CP.
Compared with the figure 1, the Wi-Fi coordination control module added in the CP is responsible for coordinating the control of the CP/AP on the Wi-Fi chip, including coordinating the priority of the business between the CP/APs, and avoiding the business failure caused by the conflict when different businesses of the CP/AP use Wi-Fi; when switching between Wi-Fi and other 3GPP systems, whether switching is carried out or not is comprehensively judged according to the priority of a wireless access technology and different scenes.
In addition, the state information (e.g., signal strength) of the Wi-Fi chip is not only reported to the AP but also to the CP. The Wi-Fi chip not only receives control commands and data from the AP, but also monitors the control commands and data from the CP, coordinates the control commands, and sends the received data to the network.
The Wi-Fi chip not only simply sends the received network data to the AP, but also needs to decide whether the data should be sent to the CP or processed by the AP according to the information carried by the data or the control information of the CP or the AP.
The technical problem of the scheme (for example, fig. 2) proposed in the embodiment of the present invention can be effectively solved, because the CP can directly receive the data sent by the network device through the non-cellular mobile communication network, and does not need to forward the data to the CP after the data is received by the AP, the phenomenon that the AP needs to be woken up is avoided, and the power consumption of the terminal concerned by the mobile terminal is reduced. Meanwhile, since the CP signaling and data do not need to be received by the AP and then forwarded to the CP through the AP, when the CP communicates with the network through Wi-Fi, as in the scheme shown in fig. 2, the data receiving efficiency is higher, and the performance such as communication delay is also more advantageous. Moreover, the scheme is more convenient for subsequent upgrading and evolution of the communication protocol. For example, when the Vowi-Fi has a telephone service, if the Wi-Fi signal quality is poor and the switching to the 5G NR is required, the AP firstly informs the CP through a control signaling, the CP judges that the NR signal quality is good, then establishes a wireless link with an access network, then establishes a link with a core network, and indicates that the AP CP NR is ready for IMS resources after the IMS service resources are reserved, and after the terminal determines that the IMS message can be normally received and sent through the NR, the terminal disconnects the Vowi-Fi and continues the IMS service on the NR. In the whole process of switching the Vowi-Fi to the VoNR, the process of establishing the Wi-Fi link and the process of establishing the NR link are relatively independent and are controlled and coordinated by the terminal. VoNR switches to VoWi-Fi similarly, with the switching duration in seconds. The longer the switching time, the higher the probability of a dropped call. In contrast, the handover between 2G/3G/4G/5G also supports reporting of signal conditions measured by the terminal device between different access technologies defined in the 3GPP specifications to the network, or actively requiring the terminal device to report signal conditions measured by various access technologies by the network according to the network distribution near the terminal device, and then initiating the handover between different access technologies by the network, in addition to the terminal device actively initiating the reselection between different access technologies, the interoperation handover between different access technologies defined in the 3GPP specifications can be generally completed within milliseconds. The advantage of switching through the interoperation mode is that the probability of service failure can be greatly reduced by switching in time. In the chip scheme of the AP and the CP in which the Wi-Fi is directly linked to the access technology defined by the 3GPP specification shown in fig. 1, when the wireless condition changes and network information needs to be shared in time, it is obviously difficult for the terminal device to complete real-time coordination and processing between the Wi-Fi and the access technology defined by the 3GPP specification in time, and it is also difficult to implement real-time initiation of handover between different access technologies defined by the Wi-Fi and the 3GPP specification according to a mutual measurement result. If the Wi-Fi and the CP are in direct communication, the terminal equipment can conveniently share and coordinate information between access technologies defined by Wi-Fi and 3GPP specifications in time, and a realization architecture and technical realization support can be provided for upgrading and evolving a communication protocol based on measurement real-time interoperation switching between the access technologies defined by the subsequent Wi-Fi and 3GPP specifications.
The technical solution of the present invention will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 3 is a flowchart illustrating a first embodiment of a data processing method according to the present invention, and the first embodiment of the present invention provides a data processing method, which can be executed by any apparatus for executing the data processing method, and the apparatus can be implemented by software and/or hardware. In this embodiment, the apparatus may be integrated in a CP of a terminal device. As shown in fig. 3, based on the architecture shown in fig. 2, the data processing method provided by the embodiment of the present invention includes the following steps:
step 301: the CP of the terminal device receives data transmitted by the network device through the non-cellular mobile communication network.
Step 302: the CP of the terminal device processes the data, or the CP of the terminal device sends the data to the AP of the terminal device, so that the AP processes the data.
In this embodiment, the terminal device includes an AP and a CP, where the AP mainly handles functions related to applications, and the CP is mainly used for handling functions such as wireless communication, for example, the terminal communicates with the network device through NR/LTE.
In addition, a non-cellular mobile communication network, which is other than a cellular mobile communication network defined by the third Generation Partnership Project (3 GPP), such as 3G, 4G, 5G, or 6G, may be linked to the CP, and may be, for example, a Wi-Fi network or an ethernet network. After the non-cellular mobile communication network is linked to the CP, when receiving the downlink data sent by the network equipment, the data sent by the network equipment is directly received by the CP through the non-cellular mobile communication network without being received by the AP and then sent to the CP. Therefore, the phenomenon that the AP needs to be awakened when the downlink data is received and the downlink data is received by the AP can be avoided, and the power consumption of the AP is reduced.
Optionally, the data may include at least one of: session Initiation Protocol (SIP) signaling, voice (voice) data, video (video) data, Access Stratum (AS) data, and Non-Access Stratum (NAS) data.
Further, after receiving the data sent by the network device through the non-cellular mobile communication network, the CP of the terminal device determines a service type of the data, where the service type includes an SIP signaling type, a voice data type, or a video data type, and thus, the CP of the terminal device determines that the CP directly processes the data according to the determined service type, or the CP sends the data to the AP of the terminal device, so that the AP processes the data.
Specifically, the data may include identification information, where the identification information is used to indicate a service type of the data, and the CP of the terminal device obtains the identification information by analyzing the received data, so as to determine the service type of the data. For example: if the identification information is "00", it may be determined that the service type of the data is the SIP signaling type, if the identification information is "01", it may be determined that the service type of the data is the voice data type, and if the identification information is "10", it may be determined that the service type of the data is the video data type.
In a possible implementation manner, if the CP of the terminal device determines that the type of the data is the SIP signaling type or the voice data type, the CP of the terminal device processes the data.
Specifically, as shown in fig. 2, if the data received by the CP of the terminal device includes the SIP signaling and the SIP module for processing the SIP signaling is located in the CP, the CP of the terminal device directly processes the SIP signaling locally after receiving the SIP signaling sent by the network device.
