Description

TECHNICAL FIELD

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

[0002] As shown in Figure 1 , a conventional wireless communication adopts a cellular network communication mode, i.e., a terminal and a network side device perform uplink / downlink data / control information transmission through a Uu interface. As shown in Figure 2 , direct communication refers to a mode in which proximal terminals can perform data transmission within a short distance range through a direct communication link (also referred to as a Sidelink (SL) or PC5 link). A wireless interface corresponding to the Sidelink link is referred to as a direct communication interface (also referred to as a Sidelink interface or PC5 interface).

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

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

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

[0006] In the prior art, for a U2N Relay scenario, there is no clear technical solution for how to ensure that a Remote UE can receive PWS related system information. SUMMARY

[0160] In the embodiments of the present application, the term "and / or" describes the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B can represent the following three cases: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after it.

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

[0162] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

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

[0164] The method and the apparatus are based on the same application concept. Since the principles of the method and the apparatus for solving problems are similar, the implementation of the apparatus and the method can be referred to each other, and the repeated parts will not be described again.

[0165] Referring to Figure 5 , Figure 5 is a flowchart of the information processing method provided by the embodiments of the present application, applied to a relay terminal which does not support PWS, such as Figure 5 includes one or more of the following steps:

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

[0167] In the embodiments of the present application, the PWS notification message can 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;

[0169] ETWS secondary notification;

[0170] CMAS notification.

[0171] In the embodiments of the present application, the relay terminal is a terminal supporting PWS or a terminal not supporting PWS. If the relay terminal supports PWS, the relay terminal needs to decode the PWS related SIB and perform other operations. 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 layer processing, and directly forwards the received SIB to the remote terminal.

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

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

[0174] Operation two, obtaining system information scheduling information from SIB1, obtaining PWS related system information from the network device according to the system information scheduling information, and forwarding the PWS related system information to the remote terminal under the condition that a first condition is met. The first condition includes receiving a PWS related system information request message sent by the remote terminal. That is, in this way, the relay terminal obtains the PWS related system information without any processing (such as decoding) and forwards it to the remote terminal under the condition that the first condition is met.

[0175] Operation three, sending the SIB1 to the remote terminal, receiving a PWS related system information request message sent by the remote terminal, obtaining system information scheduling information from the SIB1 according to the PWS related system information request message, obtaining PWS related system information from the network device according to the system information scheduling information, and forwarding the PWS related system information to the remote terminal.

[0212] 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.

[0213] It should be noted that, in Figure 6 In the embodiment shown in FIG. 6, there is no strict sequence 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 the embodiment of the present application, the relay terminal acquires PWS related system information from the network device in the case of receiving the PWS notification message, 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 acquire 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 acquired through relay terminal selection and / or reselection and other ways, so as to ensure that the remote terminal acquires the PWS related system information in time.

[0215] In the following, the specific implementation process of the present application is described in combination with different embodiments. Among them, Figures 7 to 10 In the embodiment shown in FIG. 6, the Relay UE not supporting PWS is taken as an example for description.

[0216] Referring to Figure 7 , Figure 7 is a flowchart of the information processing method provided by the embodiment of the present application. In this embodiment, the Relay UE not supporting PWS receives the PWS notification (PWS notification message), allows the Relay UE to acquire the PWS related system information from the network device, but does not do any processing, and forwards it to the Remote UE.

[0217] Step 701: The Relay UE receives a short message (Short message) from the network device.

[0218] The Relay UE receives the PWS notification message (PWS notification) through the short message, and when the etwsAndCmasIndication in the short message is set to 1, it means that there is a PWS notification.

[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, an ETWS secondary notification, and a CMAS notification.

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

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

[0224] 1) The Relay UE receives the PWS notification, reads SIB1, acquires system information scheduling information from SIB1, and acquires the PWS-related system information according to the system information scheduling information. Once the PWS-related system information is acquired, no processing (such as decoding) is performed, and the PWS-related system information is forwarded to the Remote UE.

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

[0226] 3) The Relay UE receives the PWS notification, sends SIB1 to the Remote UE. After receiving the PWS-related system information request message sent by the Remote UE, the Relay UE acquires system information scheduling information from SIB1, and acquires the PWS-related system information according to the system information scheduling information. Once the PWS-related system information is acquired, no processing (such as decoding) is performed, and the PWS-related system information is forwarded to the Remote UE.

[0227] Referring to Figure 8 , Figure 8 is a flowchart of an information processing method provided in the present application. In this embodiment, the Relay UE that does not support PWS carries first indication information in a 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 not supporting 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), the first indication information being 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 needing to acquire PWS related system information, the Remote UE takes whether the Relay UE supports PWS as a criterion for Relay UE selection and / or reselection, such as preferentially selecting a Relay UE supporting PWS.

[0232] Referring to Figure 9 , Figure 9 is a flowchart 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 carrying second indication information, the second indication information being 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, the relay discovery related message carrying second indication information, the second indication information being used to indicate the PWS support capability of the Remote UE.

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

[0236] The specific processing can include at least one of the following:

[0237] 1) If the second indication information indicates that the Remote UE supports PWS, it is determined not to send a response message to the Remote UE;

[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 comprises 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, sending the response message to the remote terminal, wherein the response message comprises 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 needing to acquire PWS related system information, the Remote UE takes whether the Relay UE supports PWS as a criterion for relay UE selection and / or reselection, such as preferentially selecting a Relay UE supporting PWS.

[0243] Referring to Figure 10 , Figure 10 is a flowchart of an 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 PWS related system information requested by the remote terminal, the Relay UE replies to the Remote UE with a response message, wherein the response message indicates that the Relay UE does not support PWS.

[0244] Step 1001: The Relay UE receives a PWS related system information request message from the 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 contains PWS related system information requested by the remote terminal, and requests PWS related system information.

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

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

[0248] The Relay UE receives the 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 UE, the Relay UE replies to the Remote UE with a response message indicating 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 PWS supporting UE, the Remote UE takes whether the Relay UE supports PWS as a criterion for Relay UE selection and / or reselection, such as preferentially selecting a Relay UE supporting PWS.

[0251] In embodiments of the present application, for example, for Figures 8 to 10 As shown in the embodiments, in the process of Remote UE performing Relay UE selection and / or reselection, any of the following principles can 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 UE does not support PWS or does not need to acquire PWS related system information, the Remote UE allows the relay terminal to be 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 UE supports PWS or needs to acquire PWS related system information, the Remote UE does not allow the relay terminal to be 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 UE does not support PWS or does not need to acquire PWS related system information, the Remote UE allows the relay terminal to be a candidate relay terminal when performing relay selection or reselection;

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

[0256] If it is determined that the relay terminal does not support PWS according to the PWS support capability of the relay terminal, the remote terminal is triggered 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 acquire PWS related system information.

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