Description

Technical Field

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

[0002] like Figure 1 As shown, traditional wireless communication adopts cellular network communication mode, that is, the terminal and the network side equipment transmit uplink and downlink data / control information through the Uu interface. Figure 2 As shown, direct communication refers to a method in which adjacent terminals can transmit data over a short distance via a direct communication link (also called Sidelink (SL), bypass or PC5 link). The wireless interface corresponding to the Sidelink link is called a direct communication interface (also called a bypass interface, Sidelink interface or PC5 interface).

[0003] In order to expand network coverage, you can consider introducing a relay. If a direct communication interface is used between the relay and the terminal (also called a remote terminal or Remote UE), then the relay is also called a sidelink relay (SL relay). The relay itself can be a terminal with a relay function. For UE-to-Network (U2N) relays, the interface between the relay and the network uses the Uu interface, and the interface between the relay and the relayed terminal (remote terminal) uses the Sidelink interface.

[0004] like Figure 3 As shown in Figure 1, a schematic diagram of a single-hop U2N Relay is shown. If the remote terminal cannot connect to the network through a relay, a multi-hop relay may be introduced, such as Figure 4 FIG. 1 is a schematic diagram of a multi-hop U2N Relay. The multi-hop U2N Relay scenario includes one U2N Relay and one or more U2U (UE-to-UE, terminal to terminal) Relays.

[0005] The Public Warning System (PWS) includes the Earthquake and Tsunami Warning System (ETWS) and / or the Commercial Mobile Alert Service (CMAS).

For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0161] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0162] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0163] The embodiments of the present application provide an information processing method and device to ensure that a remote terminal obtains PWS-related system messages in a timely manner.

[0164] Among them, the method and the device are based on the same application concept. Since the method and the device solve the problem in a similar principle, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0165] See also Figure 5 , Figure 5 is a flowchart of an information processing method provided in an embodiment of the present application, which is applied to a relay terminal that does not support PWS, such as Figure 5 As shown, it includes one or more of the following steps:

[0166] Step 501: If a PWS notification message is received, obtain PWS-related system information from a network device and forward the PWS-related system information to a remote terminal.

[0167] In an embodiment of the present application, the PWS notification message may be notified to the relay terminal by the network device in the form of a short message. The PWS includes: ETWS and / or CMAS. The PWS-related system information includes one or more of the following:

[0168] ETWS primary notification message;

[0169] ETWS secondary notification;

[0170] CMAS notification message (CMAS notification).

[0171] In the embodiment of the present application, the relay terminal is a terminal that supports PWS or a terminal that does not support PWS. If the relay terminal supports PWS, the relay terminal needs to perform operations such as decoding the PWS-related SIB; if the relay terminal does not support PWS, after receiving the PWS-related SIB according to SIB1, the relay terminal does not perform any high-level processing and directly forwards the received SIB to the remote terminal.

[0172] In this case, the relay terminal may perform one or more of the following operations:

[0173] Operation 1: obtain system information scheduling information from SIB1, obtain PWS-related system information from the network device according to the system information scheduling information, and forward the PWS-related system information to the remote terminal. That is, in this way, once the relay terminal obtains the PWS-related system information, it forwards it to the remote terminal without any processing (such as decoding).

[0174] Operation 2: Obtain system information scheduling information from SIB1, obtain PWS-related system information from the network device according to the system information scheduling information, and forward the PWS-related system information to the remote terminal if the first condition is met. The first condition includes: receiving a PWS-related system information request message sent by the remote terminal.

[0189] It should be noted that in Figure 5 In the illustrated embodiment, there is no strict order relationship between step 501 and step 502. In the embodiment of the present application, the two steps can be implemented separately or in combination.

[0190] In an embodiment of the present application, when the relay terminal receives a PWS notification message, the relay terminal obtains PWS-related system information from the network device, and forwards the PWS-related system information to the remote terminal, and / or indicates the PWS support capability of the relay terminal to the remote terminal, so that the remote terminal can obtain the PWS-related system information from the relay terminal, or, after determining the PWS support capability of the relay terminal indicated by the remote terminal, the PWS-related system information can be obtained by other methods such as selection and / or reselection of the relay terminal, thereby ensuring that the remote terminal obtains the PWS-related system message in a timely manner.

[0191] See also Figure 6 , Figure 6 is a flowchart of an information processing method provided in an embodiment of the present application, which is applied to a remote terminal, such as Figure 6 As shown, it includes one or more of the following steps:

[0192] Step 601: Receive PWS-related system information sent by a relay terminal; wherein the relay terminal is a terminal that supports PWS or a terminal that does not support PWS.

Among them, the relay discovery related message includes but is not limited to a Relay discovery announcement message. Here, the meaning of being unsuitable as a relay terminal means that the remote terminal may not give priority to using the relay terminal as a relay terminal when performing relay selection and / or reselection, that is, the relay terminal has a lower priority as a relay terminal.

[0202] Operation three, sending a relay discovery related message to the relay terminal, and receiving a response message sent by the relay terminal, and determining the PWS support capability of the relay terminal according to the response message, wherein the relay discovery related message includes second indication information, and the second indication information is used to indicate the PWS support capability of the remote terminal. The relay discovery related message includes but is not limited to a Relay discovery announcement message.

[0207] If it is determined according to the PWS support capability of the relay terminal that the relay terminal does not support PWS, and the remote terminal does not support PWS or does not need to obtain PWS-related system information, the remote terminal allows the relay terminal to be used as a candidate relay terminal when performing relay selection or reselection;

[0208] If it is determined according to the PWS support capability of the relay terminal that the relay terminal does not support PWS, and the remote terminal supports PWS or needs to obtain PWS-related system information, the remote terminal is not allowed to use the relay terminal as a candidate relay terminal when performing relay selection or reselection;

[0209] If it is determined according to the PWS support capability of the relay terminal that the relay terminal supports PWS, and the remote terminal does not support PWS or does not need to obtain PWS-related system information, the remote terminal allows the relay terminal to be used as a candidate relay terminal when performing relay selection or reselection;

[0210] If it is determined according to the PWS support capability of the relay terminal that the relay terminal supports PWS, and the remote terminal supports PWS or needs to obtain PWS-related system information, the remote terminal allows the relay terminal to be used as a candidate relay terminal when performing relay selection or reselection;

[0212] If it is determined according to the PWS support capability of the relay terminal that the relay terminal does not support PWS, the remote terminal is triggered to perform relay reselection.

[0213] It should be noted that in Figure 6 In the illustrated embodiment, there is no strict order relationship between step 601 and step 602. In the embodiment of the present application, the two steps can be implemented separately or in combination.

[0214] In an embodiment of the present application, when the relay terminal receives a PWS notification message, the relay terminal obtains PWS-related system information from the network device, and forwards the PWS-related system information to the remote terminal, and / or indicates the PWS support capability of the relay terminal to the remote terminal, so that the remote terminal can obtain the PWS-related system information from the relay terminal, or, after determining the PWS support capability of the relay terminal indicated by the remote terminal, the PWS-related system information can be obtained by other methods such as selection and / or reselection of the relay terminal, thereby ensuring that the remote terminal obtains the PWS-related system message in a timely manner.

[0215] The specific implementation process of the present application is described below in combination with different embodiments. Figures 7 to 10 In the illustrated embodiments, description is made by taking the case where the Relay UE does not support PWS as an example.

[0216] See also Figure 7 , Figure 7 This is a flow chart of the information processing method provided by the embodiment of the present application. In this embodiment, the Relay UE that does not support PWS receives a PWS notification, allowing the Relay UE to obtain PWS-related system information from the network device, but forwarding it to the Remote UE without any processing.

[0217] Step 701: Relay UE receives a short message from a network device.

[0218] Relay UE receives PWS notification message (PWS notification) through short message. When etwsAndCmasIndication in shortmessage is set to 1, it means that PWS notification exists.

[0219] The PWS includes: ETWS and / or CMAS.

[0220] Step 702: The Relay UE receives PWS-related system information from the network device.

[0221] The PWS related system information includes at least one of the following: an ETWS primary notification message (ETWS primarynotification), an ETWS secondary notification message (ETWS secondary notification), and a CMAS notification message (CMASnotification).

[0222] Step 703: Forwarding PWS related system information.

[0223] When the Relay UE receives the PWS notification, even if the Relay UE does not support PWS, it needs to obtain PWS-related system information from the network device. The specific operation can be at least one of the following:

[0224] 1) Relay UE receives PWS notification, reads SIB1, obtains system information scheduling information from SIB1, and obtains PWS-related system information according to the system information scheduling information. Once the PWS-related system information is obtained, it is forwarded to Remote UE without any processing (such as decoding).

[0225] 2) The Relay UE receives the PWS notification, reads SIB1, obtains the system information scheduling information from SIB1, and obtains the PWS-related system information according to the system information scheduling information. Once the PWS-related system information is obtained, no processing (such as decoding) is performed, and the obtained PWS-related system information is forwarded to the Remote UE when the first condition is met. The first condition is that the Relay UE receives the PWS-related system information request message sent by the Remote UE.

[0226] 3) Relay UE receives PWS notification and sends SIB1 to Remote UE. After receiving the PWS-related system information request message sent by Remote UE, Relay UE obtains system information scheduling information from SIB1 and obtains PWS-related system information according to the system information scheduling information. Once the PWS-related system information is obtained, it is forwarded to Remote UE without any processing (such as decoding).

[0227] See also Figure 8 , Figure 8 It is a flow chart of the information processing method provided by an embodiment of the present application. In this embodiment, a Relay UE that does not support PWS carries first indication information in a Relay discovery related message (relay discovery related message), and the first indication information is used to indicate the PWS support capability of the Relay UE.

[0228] Step 801: The Relay UE sends a relay discovery related message to the Remote UE.

[0229] Step 802: The Relay UE that does not support PWS carries first indication information in a relay discovery related message (such as a response message corresponding to a Relay discovery announcement or a Relay discovery solicitation), where the first indication information is used to indicate the PWS support capability of the Relay UE.

[0230] Step 803: The Remote UE performs Relay UE selection and / or reselection.

[0231] If the Remote UE is a terminal supporting PWS or a terminal that needs to obtain PWS-related system information, the Remote UE uses whether the Relay UE supports PWS as a criterion for Relay UE selection and / or reselection, such as giving priority to Relay UE supporting PWS.

[0232] See also Fig. 9 , Fig. 9 This is a flow chart of an information processing method provided by an embodiment of the present application. In this embodiment, the Relay UE receives a relay discovery related message sent by the Remote UE, the discovery message carries second indication information, and the second indication information is used to indicate the PWS support capability of the Remote UE.

[0233] Step 901: The Relay UE receives a relay discovery related message sent by the Remote UE.

[0234] The Relay UE receives a relay discovery related message (such as a Relay discovery solicitation message) sent by the Remote UE, where the relay discovery related message carries second indication information, and the second indication information is used to indicate the PWS support capability of the Remote UE.

[0235] Step 902: After receiving the relay discovery message sent by the Remote UE, the Relay UE performs relevant processing.

[0236] Specific processing may include at least one of the following:

[0237] 1) if the second indication information indicates that the remote terminal supports PWS, determine not to send a response message to the remote terminal;

[0238] 2) if the second indication information indicates that the remote terminal supports PWS, sending the response message to the remote terminal, wherein the response message includes third indication information, and the third indication information is used to indicate that the relay terminal does not support PWS;

[0239] 3) if the second indication information indicates that the remote terminal does not support PWS, sending the response message to the remote terminal;

[0240] 4) If the second indication information indicates that the remote terminal does not support PWS, send a response message to the remote terminal, wherein the response message includes third indication information, and the third indication information is used to indicate that the relay terminal does not support PWS.

[0241] Step 903: The Remote UE performs Relay UE selection and / or reselection according to the message received in step 902.

[0242] If the Remote UE is a terminal supporting PWS or a terminal that needs to obtain PWS-related system information, the Remote UE uses whether the Relay UE supports PWS as a criterion for Relay UE selection and / or reselection, such as giving priority to Relay UE supporting PWS.

[0243] See also Fig.10 , Fig.10 It is a flowchart of the information processing method provided by an embodiment of the present application. In this embodiment, the Relay UE receives a PWS-related system information request message sent by the Remote UE, and if the PWS-related system information request message contains the PWS-related system information requested by the remote terminal, the Relay UE replies with a response message to the Remote UE, and the response message indicates that the Relay UE does not support PWS.

[0244] Step 1001: Relay UE receives a PWS-related system information request message from Remote UE.

[0245] The Remote UE sends a PWS-related system information request message to the Relay UE, wherein the PWS-related system information request message includes the PWS-related system information requested by the remote terminal, and requests the PWS-related system information.

[0246] The PWS includes: ETWS and / or CMAS. The PWS related system information includes at least one of the following: ETWS primary notification message (ETWS primary notification), ETWS secondary notification message (ETWS secondary notification), CMAS notification message (CMAS notification).

[0247] Step 1002: The Relay UE sends a response message to the Remote UE.

[0248] The Relay UE receives a PWS-related system information request message sent by the Remote UE. If the PWS-related system information request message includes the PWS-related system information requested by the remote terminal, the Relay UE replies with a response message to the Remote UE, where the response message indicates that the Relay UE does not support PWS.

[0249] Step 1003: The Remote UE performs Relay UE selection and / or reselection.

[0250] If the Remote UE is a UE supporting PWS, the Remote UE uses whether the Relay UE supports PWS as a criterion for selecting and / or reselecting the Relay UE, such as giving priority to selecting the Relay UE supporting PWS.

[0251] In the embodiment of the present application, for example, Figures 8 to 10 In the embodiment shown, during the process of the Remote UE performing the Relay UE selection and / or reselection, any one of the following principles may be followed:

[0252] If it is determined according to the PWS support capability of the relay terminal that the relay terminal does not support PWS, and the remote terminal does not support PWS or does not need to obtain PWS-related system information, the remote terminal allows the relay terminal to be used as a candidate relay terminal when performing relay selection or reselection;

[0253] If it is determined according to the PWS support capability of the relay terminal that the relay terminal does not support PWS, and the remote terminal supports PWS or needs to obtain PWS-related system information, the remote terminal is not allowed to use the relay terminal as a candidate relay terminal when performing relay selection or reselection;

[0254] If it is determined according to the PWS support capability of the relay terminal that the relay terminal supports PWS, and the remote terminal does not support PWS or does not need to obtain PWS-related system information, the remote terminal allows the relay terminal to be used as a candidate relay terminal when performing relay selection or reselection;

[0255] If it is determined according to the PWS support capability of the relay terminal that the relay terminal supports PWS, and the remote terminal supports PWS or needs to obtain PWS-related system information, the remote terminal allows the relay terminal to be used as a candidate relay terminal when performing relay selection or reselection;

[0256] If it is determined according to the PWS support capability of the relay terminal that the relay terminal does not support PWS, triggering the remote terminal to perform relay reselection when a second condition is met, wherein the second condition includes that the remote terminal supports PWS or the remote terminal needs to obtain PWS-related system information;

[0257] If it is determined according to the PWS support capability of the relay terminal that the relay terminal does not support PWS, the remote terminal is triggered to perform relay reselection.
