Description

Processing method, communication device and storage medium Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a processing method, communication equipment and storage medium. Background Art

[0002] In existing protocols, when a satellite operates in a store-and-forward mode, there may be no ISL (Inter-Satellite Link, a connection between satellites).

[0003] During the process of conceiving and implementing this application, the inventors discovered at least the following problems:

[0004] Due to the high-speed movement of the satellite, in UP mode (user-plane cellular IoT evolved packet system optimization mode), when the terminal device sends an RRC connection recovery request (RRCConnectionResumeRequest), the receiving satellite may not have the terminal device context, or may not be able to obtain the terminal device context from the neighboring cell, causing the terminal device RRC connection recovery to fail. At this time, the terminal device falls back to the RRC connection establishment process, resulting in the UP mode being unusable. Therefore, it is urgent to further improve the signaling processing mechanism of the satellite (base station) store-and-forward mode to ensure that the UP mode can be used normally.

The mobile terminal 100 may include components such as an RF (Radio Frequency) unit 101, a WiFi module 102, an audio output unit 103, an A / V (Audio / Video) input unit 104, a sensor 105, a display unit 106, a user input unit 107, an interface unit 108, a memory 109, a processor 110, and a power supply 111. Those skilled in the art will understand that the mobile terminal structure shown in Figure 1 does not limit the mobile terminal. The mobile terminal may include more or fewer components than shown, or may combine certain components, or arrange the components differently.

[0103] The following is a detailed introduction to the various components of the mobile terminal in conjunction with Figure 1:

[0104] The RF unit 101 can be used to send and receive information or receive signals during calls. Specifically, it receives downlink information from the base station and transmits it to the processor 110 for processing. It also transmits uplink data to the base station. Typically, the RF unit 101 includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a low-noise amplifier, a duplexer, and / or other components. Furthermore, the RF unit 101 can communicate with the network and other devices via wireless communication.

Although FIG1 illustrates WiFi module 102, it is understood that it is not a required component of the mobile terminal and can be omitted as needed without altering the essence of the invention.

[0106] The audio output unit 103 can convert audio data received by the RF unit 101 or the WiFi module 102 or stored in the memory 109 into an audio signal and output it as sound when the mobile terminal 100 is in a call signal reception mode, a talk mode, a recording mode, a voice recognition mode, a broadcast reception mode, or the like.

The image frames processed by the GPU 1041 may be stored in the memory 109 (or other storage medium) or transmitted via the RF unit 101 or the WiFi module 102. The microphone 1042 may receive sound (audio data) in operating modes such as phone call mode, recording mode, and voice recognition mode, and may process such sound into audio data. In phone call mode, the processed audio (voice) data may be converted into a format that can be transmitted to a mobile communication base station via the RF unit 101. The microphone 1042 may implement various types of noise cancellation (or suppression) algorithms to eliminate (or suppress) noise or interference generated during the reception and transmission of audio signals.

[0108] The mobile terminal 100 also includes at least one sensor 105, such as a light sensor, a motion sensor, and other sensors.

Optionally, the user input unit 107 may include a touch panel 1071 and other input devices 1072. The touch panel 1071, also known as a touch screen, can collect user touch operations on or near it (such as operations performed by the user using a finger, stylus, or any other suitable object or accessory on or near the touch panel 1071) and drive corresponding connected devices according to a pre-set program. The touch panel 1071 may include two parts: a touch detection device and a touch controller. Optionally, the touch detection device detects the user's touch direction and detects the signal generated by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device and converts it into touch point coordinates, which are then sent to the processor 110. It can also receive and execute commands sent by the processor 110.

[0144] The embodiments of the present application take into account that when a network device (such as a base station, satellite, etc.) operates in a store-and-forward mode, there may be no ISL (connection between satellites). Due to the high-speed movement of the satellite, in UP mode (user-plane cellular Internet of Things evolved packet system optimization mode), when the terminal device sends an RRC connection recovery request (RRCConnectionResumeRequest), the receiving satellite may not have the terminal device context, and may not be able to obtain the terminal device context from the neighboring cell, causing the terminal device RRC connection recovery to fail. At this time, the terminal device falls back to the RRC connection establishment process, resulting in the UP mode being unusable.

[0145] Therefore, the embodiment of the present application mainly proposes a signaling process for the satellite (base station) storage and forwarding mode to improve the signaling processing mechanism of the satellite (base station) storage and forwarding mode.

[0149] 3. The network device receives the access request and sends an RRC release message, which carries information such as the eNB (satellite) monitoring list. (Since there is no feeder link / S1 connection between the network device and the ground, the network stores the received uplink data or signaling and decides to suspend the RRC connection.)

[0150] 4. The terminal device receives the RRC release message and saves the terminal device context;

[0151] 5. After the network device and the ground station restore the feeder link / S1 connection, the network device sends at least one of the stored uplink data or signaling, the restoration identifier list, the terminal device context information, the terminal device location information, the entry-into-force time, the validity period, the eNB list, and the terminal device context identifier to the core network device, such as providing the terminal device context information and the monitoring list or the terminal device context transfer object for the core network to confirm the terminal device context synchronization object;

[0152] 6. The core network device synchronizes the terminal device context information to the corresponding network device (base station, satellite, etc.);

[0153] 7. The terminal device monitors paging in the network device identification list or the recovery identification list or the corresponding network device that stores the terminal device context;

[0154] 8. When the terminal device monitors paging or uplink data transmission, the terminal device initiates an RRC connection recovery request, and the RRC connection recovery request carries at least one of the corresponding recovery identifier, network device identifier and terminal device context identifier;

[0155] 9. The corresponding network device (e.g., eNB2) receives the RRC connection recovery request;
