Description

Information transmission method and device, and storage medium Technical Field

[0001] The present disclosure relates to the field of communications, and in particular to an information transmission method and device, and a storage medium. Background Art

[0002] Currently, the frequencies of non-terrestrial networks (NTN) and terrestrial networks (TN) can be the same or different. For a terminal, when reselecting from an NTN cell to a TN cell, both same-frequency and inter-frequency measurements may be performed. Furthermore, for cell reselection between an NTN cell and a TN cell, the network-side equipment can configure the TN frequency to have a higher priority. In this case, the UE needs to prioritize measuring the TN frequency.

[0003] When a terminal's serving cell is an NTN cell, given the large coverage area of ​​the NTN cell, there may be no TN cells within the NTN cell, or there may be fewer TN cells within the NTN cell. In other words, there may be no TN cells around the terminal. If TN frequencies are configured with a higher priority, according to current protocols, the terminal will still need to measure TN frequencies even if there are no TN cells nearby, which will increase terminal power consumption unnecessarily.

[0107] The following first introduces the information transmission method provided by the present disclosure from the perspective of network equipment.

[0108] The present disclosure provides an information transmission method, as shown in FIG1 , which is a flow chart of an information transmission method according to an embodiment. The method may be executed by a network-side device, including but not limited to a base station and a core network device in an NTN. The method may include the following steps:

[0109] In step 101, terrestrial network TN area information is sent to a terminal.

[0110] In embodiments of the present disclosure, TN region information may refer to information related to areas covered by a TN network within the area. A network-side device may send the TN region information configured for a terminal to the terminal. The TN region information may include, but is not limited to, geographic location information of the TN region. Geographic location information may be expressed in latitude and longitude, but this disclosure does not limit this.

[0111] In a possible implementation, the TN area information may include: geographical location information of a center point of each TN area, and a radius of each TN area.

[0112] The terminal may determine a circular area with the center point as the center and a corresponding radius, and determine the circular area as a TN area.

[0113] In another possible implementation, the TN area information may include: geographical location information of multiple location points located on the boundary of each TN area.

[0114] The terminal may connect multiple location points with a straight line and determine the obtained area as the TN area. That is, the network sends multiple location information to the terminal, and the terminal obtains TN area information based on the multiple location information.

[0115] The above description is merely an exemplary description. The TN region information may include other information used to determine the TN region, which is not limited in the present disclosure.

[0116] In the above embodiment, the network side device may send TN area information to the terminal, so that the terminal performs TN frequency measurement when it is in the TN area based on the TN area information, thereby effectively reducing the power consumption of the terminal.

[0117] In some optional embodiments, referring to FIG. 2A , FIG. 2A is a flow chart of an information transmission method according to an embodiment, which may be executed by a network-side device, including but not limited to a base station and a core network device in an NTN. The method may include the following steps:

[0118] In step 201, first TN area information corresponding to a first TN area is sent to a terminal via a first system message.

[0119] In the embodiment of the present disclosure, the first system message may be a system information block (SIB), such as SIBn, where n is a positive integer.

[0120] There may be multiple first TN regions, which is not limited in the present disclosure.

[0121] That is, the network-side device in the NTN may send the first TN area information corresponding to the first TN area configured for the terminal to the terminal through the first system message.

[0122] In a possible implementation, the first TN area information may include: geographical location information of a center point of each first TN area, and a radius of each first TN area.

[0123] In another possible implementation, the first TN region information may include: geographical location information of a plurality of location points located on a boundary of each first TN region.

[0124] In the above embodiment, the network side device may send the first TN area information to the terminal through the first system message, so that the terminal performs TN frequency measurement when it is in the corresponding first TN area, thereby effectively reducing the power consumption of the terminal.

[0125] In some optional embodiments, referring to FIG. 2B , FIG. 2B is a flow chart of an information transmission method according to an embodiment, which may be executed by a network-side device, including but not limited to a base station and a core network device in an NTN. The method may include the following steps:

[0126] In step 201 ′, second TN area information corresponding to the second TN area is sent to the terminal via a first radio resource control RRC message.

[0127] In the embodiment of the present disclosure, considering that the number of first TN areas is large, the network side device will occupy more signaling resources when sending the first TN area information to the terminal. In order to reduce the occupation of network side signaling resources, the network side device can filter the first TN areas.

[0128] After establishing a Radio Resource Control (RRC) connection with the terminal, the network device can determine the terminal's geographic location information. Therefore, based on the terminal's geographic location information, the network device can filter out a portion of the area surrounding the terminal from the first TN area, i.e., filter out a second TN area. Furthermore, the network device can send second TN area information corresponding to the second TN area to the terminal via a first RRC message.

[0129] In a possible implementation, the second TN region information may include: geographical location information of a center point of each second TN region, and a radius of each second TN region.

[0130] In another possible implementation, the second TN region information may include: geographical location information of a plurality of location points located on the boundary of each second TN region.

[0131] In the above embodiment, the network side device may send the second TN area information to the terminal through the first RRC message, so that the terminal performs TN frequency measurement when it is in the corresponding second TN area, effectively reducing the power consumption of the terminal.

[0132] In some optional embodiments, referring to FIG. 2C , FIG. 2C is a flow chart of an information transmission method according to an embodiment, which may be executed by a network-side device, including but not limited to a base station and a core network device in an NTN. The method may include the following steps:

[0133] In step 201″, first TN area information corresponding to a first TN area is sent to a terminal via a first system message.

[0134] The implementation of step 201 is similar to that of the above step 201 and will not be repeated here.

[0135] In step 202″, second TN area information corresponding to the second TN area is sent to the terminal through a first radio resource control RRC message.

[0136] The implementation of step 201" is similar to that of step 201', and will not be repeated here.

[0137] In the above embodiment, the network side device can send the first TN area information to the terminal through the first system message. Furthermore, after establishing an RRC connection with the terminal, the network side device sends the second TN area information to the terminal through the first RRC message, so that the terminal performs TN frequency measurement when it is in the corresponding second TN area, effectively reducing the terminal power consumption.

[0138] In some optional embodiments, referring to FIG. 3 , which is a flow chart of an information transmission method according to an embodiment, the method may be executed by a network-side device, including but not limited to a base station and a core network device in an NTN. The method may include the following steps:

[0139] In step 301, first TN area information corresponding to a first TN area is sent to a terminal via a first system message.

[0140] In the embodiment of the present disclosure, the first system message may be a SIB, such as SIBn, where n is a positive integer.

[0141] There may be multiple first TN regions, which is not limited in the present disclosure.

[0142] That is, the network-side device in the NTN may send the first TN area information corresponding to the first TN area configured for the terminal to the terminal through the first system message.

[0143] In step 302, a first distance threshold is sent to the terminal.

[0144] In the embodiment of the present disclosure, the first distance threshold is used by the terminal to determine target TN area information that needs to be saved in the first TN area information.

[0145] In an embodiment of the present disclosure, after the network side device sends the first TN area information to the terminal through the first system message, in order to reduce the occupation of terminal resources, the network side device can also configure a first distance threshold for the terminal and send the first distance threshold to the terminal so that the terminal can determine the target TN area information that the terminal needs to save in the received first TN area information.

[0146] In a possible implementation, the network-side device may send the first distance threshold to the terminal through a second system message.

[0147] Optionally, the second system message and the first system message may use the same or different SIBs, for example, the first system message may be SIB1, and the second system message may be SIBm, where m is greater than 1. For another example, both the first system message and the second system message may use SIB1.

[0148] In another possible implementation, the network-side device may send the first distance threshold to the terminal through a second RRC message.

[0149] Optionally, the second RRC message and the first RRC message are the same or different RRC messages, which is not limited in this disclosure.

[0150] In the above embodiment, the network side device may send the first distance threshold to the terminal, so that the terminal can determine the target TN area information to be saved in the first TN area information, thereby avoiding wasting terminal resources and improving availability.

[0151] In some optional embodiments, referring to FIG. 4A , FIG. 4A is a flow chart of an information transmission method according to an embodiment, which may be executed by a network-side device, including but not limited to a base station and a core network device in an NTN. The method may include the following steps:

[0152] In step 401, when the second TN area information is sent to the terminal through the first RRC message, validity indication information is sent to the terminal.

[0153] In the embodiment of the present disclosure, the validity indication information is used to indicate the validity of the second TN area information.

[0154] In a possible implementation, the validity indication information includes at least one of the following: a validity period of the second TN area information; and a second distance threshold for determining a valid distance range of the second TN area information.

[0155] The terminal may determine the validity of the second TN area information based on the validity indication information.

[0156] The valid duration may be used by the terminal to determine the maximum duration during which the second TN area information is valid.

[0157] The second distance threshold may be used as the maximum distance that the terminal can move relative to the second designated location when the terminal determines that the second TN area information is valid. The second designated location is the geographical location of the terminal when the second TN area information is received, or the second designated location is the geographical location of the terminal when the second distance value is determined, which is not limited in this disclosure.

[0158] Accordingly, the terminal may determine that the second TN area information is invalid when the validity period is exceeded. And / or, the terminal may determine a valid distance range for the second area information based on a second distance threshold, and determine that the second TN area information is invalid when the terminal moves out of the valid distance range.

[0159] In the above embodiment, the network side device can send validity indication information to the terminal, where the validity indication information is used to indicate the validity of the second TN area information configured by the network side device for the terminal, thereby improving the reliability of determining the second TN area and effectively reducing the power consumption of the terminal.

[0160] In some optional embodiments, referring to FIG. 4B , FIG. 4B is a flow chart of an information transmission method according to an embodiment, which may be executed by a network-side device, including but not limited to a base station and a core network device in an NTN. The method may include the following steps:

[0161] In step 401', the validity indication information reported by the terminal is received.

[0162] In the embodiment of the present disclosure, the validity indication information is used to indicate the validity of the second TN area information.

[0163] In a possible implementation, the validity indication information includes at least one of the following: a validity period of the second TN area information; and a second distance threshold for determining a valid distance range of the second TN area information.

[0164] In the embodiment of the present disclosure, the terminal may determine the validity indication information based on the terminal capability and report it to the network side device.

[0165] In step 402', when the second TN area information is sent to the terminal through the first RRC message, validity indication information is sent to the terminal.

[0166] In the embodiment of the present disclosure, the network side device may determine the validity indication information to be finally used based on the validity indication information reported by the terminal and send the result to the terminal.

[0167] For example, if the terminal reports validity indication information, and the validity indication information includes the validity duration, the network side device may determine a shorter validity duration based on the validity duration reported by the terminal, and send the shorter validity duration to the terminal. Alternatively, the network side device may send the shorter validity duration reported by the terminal as the validity duration of the second TN area information to the terminal.

[0168] For another example, the terminal reports validity indication information, and the validity indication information includes the valid duration. The network side device can use the valid duration reported by the terminal as the valid duration of the second TN area information. In addition, the network side device can configure a second distance threshold for the terminal, and further send the valid duration and the second distance threshold together to the terminal.

[0169] For another example, if the terminal reports validity indication information, and the validity indication information includes the validity duration and the second distance threshold, the network device may determine the validity duration of the second TN area information based on the validity duration reported by the terminal, and the validity duration determined by the network device is less than or equal to the validity duration reported by the terminal. In addition, the network device may determine the second distance threshold, and the second distance threshold determined by the network device is less than or equal to the second distance threshold reported by the terminal. Furthermore, the network device sends the determined validity duration and the second distance threshold together to the terminal.

[0170] The above description is merely an exemplary description, and all solutions in which the terminal reports validity indication information to assist the network-side device in determining the validity of the second TN area information should fall within the scope of protection of the present disclosure.

[0171] In the above embodiment, the terminal can report the validity indication information based on the terminal capability, and assist the network side device in determining the validity indication information of the second TN area information, thereby improving the reliability of the validity indication information.

[0172] In some optional embodiments, referring to FIG. 5 , which is a flow chart of an information transmission method according to an embodiment, the method may be performed by a network-side device, including but not limited to a base station and a core network device in an NTN. The method may include the following steps:

[0173] In step 501, terminal capability information reported by the terminal is received.

[0174] In the embodiment of the present disclosure, the terminal capability information is used to indicate whether the terminal has the capability to support the TN area.

[0175] In a possible implementation, the terminal capability information may also be used to indicate the capability of the terminal to support the number of TN areas.

[0176] In step 502, when it is determined based on the terminal capability information that the terminal has the capability to support the TN region, the TN region information is sent to the terminal.

[0177] In an embodiment of the present disclosure, when the network-side device determines that the terminal has the ability to support the TN area based on the terminal capability information reported by the terminal, the TN area information can be sent to the terminal.

[0178] The network side device may send the TN area information to the terminal through a first system message and / or a first RRC message, and the amount of TN area information sent may be determined based on the terminal capability information.

[0179] For example, the terminal capability information indicates that the terminal has the ability to support TN areas, and the number of supported TN areas is 4. The network side device can determine, based on the terminal capability information, that the terminal has the ability to support TN areas, and send the first TN area information to the terminal through the first system message. Furthermore, the network side device can send the second TN area information to the terminal through the first RRC message, where the number of the second TN areas can be less than or equal to 4.

[0180] In the above embodiment, the network side device can receive the terminal capability information reported by the terminal, thereby configuring and sending TN area information for the terminal based on the terminal capability, thereby improving the reliability of TN area information configuration.

[0181] Next, the information transmission method provided by the present disclosure will be introduced from the terminal side.

[0182] An embodiment of the present disclosure provides an information transmission method. As shown in FIG6 , FIG6 is a flow chart of an information transmission method according to an embodiment, which can be executed by a terminal. The method may include the following steps:

[0183] In step 601, ground network TN area information sent by a network side device is received.

[0184] In the embodiments of the present disclosure, TN area information may refer to information related to areas covered by the TN network within the area. TN area information may include, but is not limited to, geographic location information of the TN area. Geographic location information may be represented by latitude and longitude, which is not limited in the present disclosure.

[0185] In a possible implementation, the TN area information may include: geographical location information of a center point of each TN area, and a radius of each TN area.

[0186] The terminal may determine a circular area with the center point as the center and a corresponding radius, and determine the circular area as a TN area.

[0187] In another possible implementation, the TN area information may include: geographical location information of multiple location points located on the boundary of each TN area.
