This disclosure claims priority to Chinese Patent Application No. 202210805873.4 filed in China on July 8, 2022, the entire content of which is incorporated herein by reference.

Technical field

The present disclosure relates to the field of communication technology, and in particular, to an information processing method, device and readable storage medium.

Background technique

In order to expand network coverage, when the user equipment (UE) signal in the cell is poor, you can consider connecting to the relay UE (relay UE) to continue the connection and data transmission in the current cell. The relay UE itself is a terminal with relay function. A UE connected to the network through a relay UE is called a remote UE (remote UE).

For UE-to-network relay, the relay UE and the remote UE communicate through the direct communication link (sidelink) direct communication interface, and the air interface link is used between the relay UE and the network/base station. Communicate via Uu link. The wireless interface corresponding to the Sidelink link is called the direct communication interface (also called Sidelink interface, bypass interface or PC5 interface).

In related technology, sidelink allows remote UE to access the network side through a single link connection of a single relay UE. Furthermore, a multi-path scenario is introduced, that is, the remote UE can access the network side through at most one relay UE and one direct Uu port link to improve the reliability and peak rate of the remote UE's access to the network. Among them, the way in which the UE connects to the network side through the Uu port is called the direct connection mode, and the way in which the UE is relayed through the relay is called the indirect connection mode.

Terminal history information (UE history information) may include information related to one or more cells where the UE camps/accesses, and may have multiple entries. The recording of entries is mainly divided into two situations: an independent entry for each cell information within coverage (in coverage), and an independent entry for the situation of loss of coverage (out of coverage). The UE can indicate and report to the network side after having the UE history information storage capability and saving the UE history information.

In some cases, the historical information reported by the UE can be used to collect statistics on UE paths and coverage. However, the terminal history information reported in accordance with related technologies may make it impossible for the network side to accurately count the UE's access path or coverage status.

Detailed ways

In the embodiment of this disclosure, the term "and/or" describes the association relationship of associated objects, indicating that there may be Three relationships, for example, A and/or B, can represent: A exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the related objects are in an "or" relationship.

In the embodiment of this disclosure, the term "plurality" refers to two or more than two, and other quantifiers are similar to it.

The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only some of the embodiments of the present disclosure, not all of them. Based on the embodiments in this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of this disclosure.

In related technology, if the terminal historical information includes the following content, it can be used to collect statistics on the terminal’s connection path and coverage:

In the case of in coverage, including the cell identification information and time length of the special cell (Special Cell, Spcell) (primary cell (PCell) and/or the primary serving cell (Primary secondary cell, PSCell) of the secondary cell group) ;

Out of coverage (without PCell and/or PSCell), including the length of time.

If according to the relevant method, the terminal history information only records the information and connection duration of the cell when the terminal is in coverage, the terminal using the indirect mode may also be within the coverage of the cell, but because the relay UE is It is removable. If there is currently no relay UE connection, the coverage state may be lost. Therefore, in a related manner, the terminal history information will not correctly reflect the terminal's connection status and path information.

If the remote UE can access the network through direct or indirect, the specific method chosen depends on the implementation of the terminal. Therefore, when the remote UE accesses the network in an indirect manner, the network device cannot determine based on the relevant terminal history information that the current remote UE can still be in the in-coverage state after the relay UE is removed, thus affecting the network device's access to the remote UE.

In this case, the relay terminal is equivalent to the remote terminal of other relay terminals. For example, remote terminal A is connected to relay terminal B, and relay terminal B is connected to relay terminal C and accesses the network.

Referring to Figure 3, Figure 3 is a flow chart of an information processing method provided by an embodiment of the present disclosure. As shown in Figure 3, it includes the following steps:

Step 301: The network device receives the terminal history information sent by the terminal.

Here, the network device can receive the terminal history information sent by the remote terminal, and can also receive the terminal history information sent by the remote terminal. Following the terminal history information sent by the terminal.

The meaning of the terminal history information may refer to the description of the foregoing method embodiment.

Step 302: The network device determines the connection path or coverage of the terminal based on the terminal historical information.

In the embodiment of the present disclosure, the network device may determine the connection path or coverage of the terminal according to the terminal historical information. When the terminal historical information includes multiple pieces of information, if the results determined based on the multiple pieces of information are different, the network device can also select a certain result as the final determination result based on a certain policy. For example, randomly select a certain result as the final determined result, etc.

For example, for a remote terminal, if the terminal history information includes a first indication, that is, indicating whether a cell signal is measured, at this time, if the first indication is used to indicate that a cell signal is measured, then it can be determined that the terminal is directly connected Enter the cell, that is, access the network through a direct connection; otherwise, the network device can determine that the terminal accesses the network through an indirect connection. For another example, the terminal history information also includes the identifier of the third cell. If the third cell is the cell that the remote terminal currently accesses through the relay terminal, it can be determined that the remote terminal accesses the network through direct connection. The terminal terminal is also more likely to be under the coverage of the current cell; if the third cell is a cell other than the cell that the remote terminal currently accesses through the relay terminal, then if the remote terminal does not pass through the relay terminal Relay, it can be determined that the remote terminal accesses the network through direct connection, and the remote terminal is also likely to be under the coverage of other cells.

For another example, for a relay terminal, if the terminal history information includes a fourth indication, and the fourth indication is used to instruct the relay terminal to connect to the remote terminal, it can be determined that the relay terminal accesses the network through direct connection. , and is more likely to be within the coverage of the current cell.

Below, the implementation process of the embodiment of the present disclosure is described in combination with different scenarios.

In related technologies, for a remote UE, if it is connected to a relay UE and then accesses a cell, according to the relevant method, the remote UE only records the currently accessed cell information, including the cell identity, in the terminal history information. Duration information. If the relay UE moves and can no longer provide relay services for the remote UE, will the remote UE be able to directly access the cell and access the network, or will it be in a state of losing network connection? The network equipment will not be able to pass through the relevant terminal. Judgment based on historical information. Therefore, the network device may be biased in its judgment of the path of the remote UE that accesses the network through the relay UE.

To address this situation, in the embodiment of the present disclosure, the base station/cell information is recorded by the remote UE. The terminal history information includes the following content:

Whether the base station/cell signal is measured;

If the cell signal can be measured, the identity of the cell whose signal is measured or the identity of the cell with the best signal among the cells whose signal is measured;

If the cell signal can be measured, the signal strength and/or signal quality of the cell whose signal is measured;

If the cell signal can be measured, whether the signal strength/quality of the cell whose signal is measured meets the connection conditions or exceeds the threshold.

For network equipment, if the remote UE can directly measure the signal of the base station/cell when accessing the network through the relay UE, and the directly measured signal of the base station/cell can meet the access conditions, then the remote UE leaves the relay The UE's transit can still be connected to the network through direct connection. At this time, the network device can determine the network to which the remote UE is connected through direct connection. If the remote UE cannot measure the signal of any base station/cell, or the directly measured signal of the base station/cell cannot meet the access conditions, the remote UE will be in the out of coverage state after leaving the relay UE, that is, losing the network Coverage status.

In practical applications, when remote UE measures cell signals, it may measure signals from multiple cells. If the cell with the best signal is the cell that the remote UE currently accesses through relay UE, then the remote UE has a greater probability of being under the coverage of the current cell through direct connection; if the cell with the best signal is the cell that the remote UE currently accesses through relay If the remote UE does not go through relay to access other cells other than the cell to which the UE is relayed, then the remote UE has a higher probability of being under the coverage of other cells through direct connection instead of currently going through relay. The UE accesses the cell.

Through the terminal history information of the embodiment of the present disclosure, for the remote UE that accesses the network through relay UE relay, the network device can learn whether the remote UE can have guaranteed access to the network, instead of only passing the signal relayed through relay UE in an unguaranteed manner. Status access to the network; the network device can also learn whether the remote UE is within the coverage of the current cell when it accesses the network through direct connection, or where it is. under the coverage of neighboring cells.

In related technologies, if the remote UE accesses the network through multiple relay UEs when accessing the same cell, that is, the remote UE changes different relay UEs to access the network when accessing the same cell; or, when the remote UE accesses the network, When the UE accesses the network through multi-path/multi-connection, the remote UE accesses a cell. Whether it directly accesses the cell through direct connection or indirectly accesses the cell via relay UE depends on the specific implementation. Therefore, it may actually happen that the remote UE changes the relay UE within the time it accesses a cell, or switches between direct connection and non-direct connection modes.

For the scenario where the relay UE is replaced, according to the recording method in related technologies, only the current cell identity and the length of access to the cell are recorded in one entry, without distinguishing the details of access to the cell. The network The device will not be able to tell whether there is a loss of coverage and cannot access the cell using a direct path. Therefore, it is necessary to record the time points/time periods when the remote UE passes through multiple relay UEs, and record whether the signal of the base station/cell can be directly measured within the time of passing through each relay UE, and whether it can be measured directly. The signal of the base station/cell reached can meet the access conditions. That is, in this case, in addition to recording the terminal history information that is the same as the previous scenario, it is also possible to record the time information when the remote UE accesses the cell through different relay UEs that have been replaced, the identity of the relay UE that has been replaced, and other information. .

If the remote UE accesses the network through multi-path or multi-connection technology, in addition to recording the same terminal history information as the previous scenario, the remote UE can also record the information of the cells covered or included by multiple paths/multiple connections at the same time. identification, the identification of relay UE, the time when remote UE accesses the network through each relay UE, etc.

Optionally, in this scenario, the terminal history information also includes one or more of the following:

Information indicating whether the remote UE accesses the network status through a multi-hop relay;

The number of hops that the remote UE passes when accessing the network through a multi-hop relay;

When the remote UE is accessing the network through a multi-hop relay, the identification of one or more relay terminals in the multi-hop relay passed;

The interface signal type between the remote UE and the accessed relay terminal;

Measurement results of the interface, which is the interface between the remote UE and the accessed relay terminal;

The location information of the remote UE.

In the embodiment of the present disclosure, the relay UE can also record terminal history information.

When the distance between a certain UE and the base station meets the conditions, it can serve as a relay UE and serve other remote UEs to relay data. In order to meet the operator's big data statistics needs, similar to the terminal history information recorded by remote UE, to meet the requirements of relay UE, the following information can also be recorded in the terminal history information:

When connected to the cell, whether the relay UE is actually connected to the remote UE, the number of remote UEs connected to the relay UE, the identity of the remote UE, and the measurement results of the PC5 interface between the remote UE and the relay UE; relay UE and remote The UE has the time information of the PC5 connection, including time point, time period or absolute time information, etc.

When a relay UE is connected to other relay UEs (multi-hop scenario), the relay UE can also be processed in the same way as the aforementioned remote UE, recording the relay UE with the previous hop (relay UE closer to the network) Relevant indication information is used to enable network equipment to know whether the current relay UE can have guaranteed access to the network, instead of only accessing in an unguaranteed state through signals relayed by other relay UEs; and to learn that the current relay UE is connected through direct connection. Whether it is within the coverage of the current cell when entering the network, or under the coverage of which neighboring cell.

Among them, the terminal history information recorded by the relay UE may include:

An indication used to indicate whether the relay UE has measured a cell signal; if a cell signal has been measured, the information of the cell where the signal has been measured; if the relay UE has changed to a different other relay UE in a certain cell and accessed the cell , the time information of the relay UE accessing the cell through different other relay UEs and/or the identification of the other relay UEs; if the relay UE accesses the network through multi-paths, the time information covered by one or more paths One or more of the cell identifier, the identifier of other relay UEs included, and the time information of accessing the network through other relay UEs; if the relay UE accesses the network through multi-connection technology, one or more connections include One or more of the cell identifiers, the identifiers of other relay UEs included, and the time information of accessing the network through other relay UEs.

Among them, the information of the cell where the signal is measured may include the identity of the cell, signal strength, signal quality, whether the signal strength of the cell meets the connection conditions or is greater than a certain threshold, and whether the signal quality of the cell meets the connection conditions or is greater than a certain threshold. threshold and so on. Among them, the threshold can be adjusted as needed To set.
