Abstract
Description
Technical Field
[0001] This invention relates to the field of mobile communication technology, and more specifically to an access method and device for a relay terminal. Background Technology
[0002] With the diversification of 5G terminals, more and more wearable devices need to access the network. In order to reduce power consumption, wearable devices can access the network through other terminals (such as mobile phones) instead of connecting to base stations, that is, by using other terminals as relays to access the network.
[0003] In existing technologies, relay nodes typically forward received data directly without any processing or differentiation; that is, relay nodes do not distinguish between remote nodes. When a remote node connects to a relay node, it may or may not be aware of the relay node. Therefore, existing relay nodes struggle to provide differentiated services for remote terminals.

[0092] As described in the background section, in existing technologies, relay terminals do not provide differentiated services for different remote terminals when providing relay services to multiple remote terminals. However, in some scenarios, a user's smartphone, acting as a relay terminal, may provide services to multiple remote terminals, including the user's own wearable devices and those of other users. Therefore, existing technologies suffer from the following problem: they cannot distinguish between remote terminals; all remote terminals may connect to the smartphone, thus preempting bandwidth that should be used for the user's smartphone and wearable devices. In other words, existing relay solutions fail to provide differentiated services for different remote terminals. Therefore, this invention provides a solution for remote terminals to access a relay terminal, enabling differentiated access control of remote terminals by the relay terminal.
[0093] Please refer to Figure 1 The present invention provides an access method for a relay terminal, which, when applied to a first remote terminal, includes:
[0094] Step 11: Determine the target access configuration information used by the first remote terminal when accessing the first relay terminal, based on the group to which the first remote terminal belongs and the access configuration information corresponding to at least one group.
[0095] Here, the at least one group may include at least one of a default group, a first group, and a second group, wherein:
[0096] The default group is a group set for terminals that have not yet joined any group;
[0097] The first group is the group to which the first relay terminal belongs;
[0098] The second group is a different group from the default group and the first group, and there may be one or more second groups.
[0099] Each group can be distinguished and indicated by its corresponding group identifier.
[0100] In addition, in order to prioritize providing services to remote terminals in the group to which the first relay terminal belongs, the access configuration information corresponding to the first group can have the highest access priority among the access configuration information corresponding to the at least one group.
[0101] In this embodiment of the invention, the access configuration information corresponding to the at least one group includes at least one of the following:
[0102] a) At least one access control parameter corresponding to a packet.
[0103] Here, the access control parameters may include at least one of the following parameters: access probability factor, first backoff time, and radio resource configuration information; wherein,
[0104] The access probability factor is the probability of a remote terminal successfully initiating an access request. For example, the access probability factor can be a number between 0 and 1.
[0105] The first rollback time is the waiting time between two attempts to initiate random access;
[0106] The wireless resource configuration information is: the wireless resources used when a remote terminal initiates random access.
[0107] b) At least one random access preference parameter corresponding to a packet.
[0108] Here, the random access priority parameters include at least one of the following parameters: power boost step size, second backoff time; wherein,
[0109] The power boost step size is used to represent the magnitude of the transmission power adjustment. The larger the power boost step size, the greater the magnitude of the transmission power adjustment, which is more conducive to being detected by the network as soon as possible. In other words, it is easier to successfully access the network randomly, which is equivalent to having a higher access priority.
[0110] The second rollback time is the waiting time between two random access attempts.
[0111] Step 12: Based on the target access configuration information, initiate access to the first relay terminal.
[0112] Here, based on the target access configuration information, initiating access to the first relay terminal may specifically include:
[0113] Step A: The first remote terminal generates a random number. The value range of this random number can be the same as that of the access probability factor, for example, both are between 0 and 1.
[0114] Step B: The first remote terminal compares the random number with the target access probability factor in the target access configuration information. If the random number is less than the target access probability factor, proceed to step C; otherwise, proceed to step D.
[0115] Step C: The first remote terminal sends a random access request to the first relay terminal to access the first relay terminal. At this time, the first remote terminal can determine available radio resources based on the radio resource configuration information in the target access configuration information and send the random access request. Furthermore, if the random access fails after sending the random access request to the first relay terminal, the random access request is sent again after waiting for the second backoff time specified in the target access configuration information.
[0116] Step D: After waiting for the first rollback time in the target access configuration information, the first remote terminal returns to step A to regenerate a random number and retry initiating access.
[0117] As can be seen, by using different access probability factors, first backoff times, second backoff times, and radio resource configuration information, this embodiment of the invention can achieve differentiated access services with different priorities. For example, the access configuration information corresponding to the first group usually has the highest access priority, that is, the access probability factor of the first group is greater than that of other groups (such as the second group and the default group); the first backoff time of the first group is less than that of other groups (such as the second group and the default group); the second backoff time of the first group is less than that of other groups (such as the second group and the default group), and so on. By using the access configuration information corresponding to different groups, differentiated access control can be provided for terminals in different groups.
[0118] Through the above steps, this embodiment of the invention utilizes grouping to perform differentiated access control management for remote terminals. When a remote terminal accesses a relay terminal, it determines the access configuration information to be used based on its own group, thereby enabling the provision of differentiated access services to different remote terminals using grouping. For example, if two groups have different access configuration information, different access services can be provided to terminals in those two groups.
[0119] Prior to step 11 above, the first remote terminal can pre-obtain access configuration information corresponding to at least one packet. For example, the non-access stratum (NAS layer) or application layer can pre-configure the access configuration information on the first remote terminal, allowing the first remote terminal to directly obtain the locally configured access configuration information corresponding to the at least one packet. Alternatively, configuration can be performed via the air interface, where the first remote terminal receives access configuration information corresponding to at least one packet sent by the first relay terminal, thereby obtaining the aforementioned access configuration information. The first remote terminal can receive the aforementioned access configuration information sent by the first relay terminal through a direct communication interface (also known as the Sidelink interface or PC5 interface).
[0120] Similarly, the packet to which the first remote terminal belongs can be pre-configured locally or configured by the relay terminal. Before step 11 above, the NAS layer or application layer can pre-configure the packet for the first remote terminal, allowing the first remote terminal to obtain the locally configured packet to which it belongs and thus determine its own packet. Alternatively, configuration can be performed via the air interface, where the first remote terminal receives a packet configuration message sent by the first relay terminal, thereby obtaining the packet configured by the first relay terminal for the first remote terminal. Here, the first relay terminal can configure the packet to which it belongs based on its identity identifier (ID).
[0121] Figure 2 A sample workflow for configuring remote terminal packets on a relay terminal is provided, including:
[0122] Step 21: The first relay terminal sends a packet configuration message to the first remote terminal. The packet configuration message includes a packet identifier assigned by the first relay terminal to the first remote terminal. The first remote terminal receives the packet configuration message sent by the first relay terminal.
[0123] Step 22: When the first remote terminal determines that it wants to join the group corresponding to the group identifier, it sends a group configuration response message to the first relay terminal. The group configuration response message carries the terminal identifier of the first remote terminal and the group identifier, indicating that the first remote terminal expects to join the group corresponding to the group identifier.
[0124] Step 23: After receiving the above-mentioned group configuration response message, the first relay terminal sends a group configuration confirmation message to the first remote terminal. The first remote terminal then receives the group configuration confirmation message sent by the first relay terminal. The group configuration confirmation message is used to confirm that the first remote terminal has joined the group corresponding to the group identifier, thereby completing the group configuration process.
[0125] In step 22 above, if the first remote terminal does not agree to join the group corresponding to the group identifier, it can send a group configuration rejection message to the first relay terminal to indicate its refusal to join the group corresponding to the group identifier. After receiving the group configuration rejection message, the first relay terminal can reassign another group identifier to the first remote terminal or terminate the process.
[0126] In step 11 of this embodiment of the invention, the first remote terminal determines the target access configuration information to be used when accessing the first relay terminal based on its own group and access configuration information corresponding to at least one pre-obtained group. The specific determination method may include at least one of the following:
[0127] 1) If the first remote terminal and the first relay terminal belong to the same group, the target access configuration information is determined to be the access configuration information corresponding to the first group;
[0128] 2) If the first remote terminal has not yet joined any group, determine that the target access configuration information is the access configuration information corresponding to the default group;
[0129] 3) If the group to which the first remote terminal belongs is the second group, the target access configuration information is determined to be the access configuration information corresponding to the second group.
[0130] In addition, in this embodiment of the invention, the first remote terminal may also perform cell reselection to camp on a cell other than the current cell. In order to enable the first remote terminal to obtain better relay service, when performing cell reselection, the first remote terminal will prioritize reselecting to a relay terminal that belongs to the same packet as itself.
[0131] Specifically, each relay terminal can broadcast its own packet identification information, which indicates the packet to which the relay terminal belongs. Thus, the first remote terminal receives packet identification information from at least one relay terminal, indicating the packet to which the relay terminal belongs; then, if a second relay terminal with the same packet as the first remote terminal exists among the at least one relay terminal, the first remote terminal determines the target relay terminal for cell reselection according to any of the following methods:
[0132] Method 1: When the second relay terminal meets the preset quality threshold requirements, the second relay terminal is used as the target relay terminal.
[0133] Here, when there are multiple second relay terminals, one of the second relay terminals can be selected as the target relay terminal based on conditions such as signal quality.
[0134] Method 2: Use a preset bias to correct the signal quality parameters of the second relay terminal, wherein the corrected signal quality parameters are better than the uncorrected signal quality parameters; select the relay terminal with the best signal quality based on the signal quality parameters of the at least one relay terminal as the target relay terminal.
[0135] Here, by modifying the signal quality parameters, the likelihood of the second relay terminal being selected as the target relay terminal is increased, and the reselection priority of the second relay terminal is improved.
[0136] Method 3: Determine the priority of the at least one relay terminal, wherein the priority of the second relay terminal is higher than that of other relay terminals besides the second relay terminal; select a target relay terminal from the at least one relay terminal according to the priority.
[0137] Here, a higher priority is directly set for the second relay terminal. Of course, when resetting, in addition to considering the priority, other parameters, such as signal quality, can also be combined to make a comprehensive decision.
[0138] When a first remote terminal initially connects to a relay terminal, if the first remote terminal has already joined a certain group (i.e., it has a group identifier configured), it can select a target relay terminal for access in a manner similar to cell reselection described above. That is, during initial access, the first remote terminal prioritizes selecting a relay terminal belonging to the same group as itself. Specifically, the terminal can determine the target relay terminal for initial access using any of the methods 1 to 3 above.
[0139] Please refer to Figure 3 The present invention provides an access method for a relay terminal, which, when applied to the first inter-terminal side, includes:
[0140] Step 31: Send at least one packet corresponding to the access configuration information to the first remote terminal. The access configuration information corresponding to the at least one packet is used by the first remote terminal to determine the target access configuration information to be used when accessing the first relay terminal.
[0141] Through the above steps, the first relay terminal sends access configuration information corresponding to at least one packet to the first remote terminal. In this way, when the first remote terminal accesses the first relay terminal, it can determine the target access configuration information used by the first remote terminal to access the first relay terminal based on the packet to which the first remote terminal belongs and the access configuration information corresponding to at least one packet. Then, it initiates access based on the target access configuration information, thereby realizing differentiated access control of the remote terminal by the relay terminal using the access configuration information.
[0142] Optionally, the at least one group includes at least one of a default group, a first group, and a second group, wherein:
[0143] The default group is a group set for terminals that have not yet joined any group;
[0144] The first group is the group to which the first relay terminal belongs;
[0145] The second group is a group that is different from the default group and the first group.
[0146] Among the access configuration information corresponding to the at least one group, the access configuration information corresponding to the first group has the highest access priority.
[0147] In this embodiment of the invention, the first relay terminal can also be configured with the group to which the first remote terminal belongs. For detailed configuration procedures, please refer to [reference needed]. Figure 2 The first relay terminal sends a packet configuration message to the first remote terminal, the packet configuration message including a packet identifier assigned to the first remote terminal. Then, the first relay terminal receives a packet configuration response message sent by the first remote terminal if it has determined to join the packet corresponding to the packet identifier; the packet configuration response message carries the terminal identifier of the first remote terminal and the packet identifier. Next, the first relay terminal sends a packet configuration confirmation message to the first remote terminal, the packet configuration confirmation message confirming that the first remote terminal has joined the packet corresponding to the packet identifier, thereby completing the packet configuration process for the first remote terminal. Through the above process, the first remote terminal joins the packet corresponding to the packet identifier.
[0148] The various methods of the embodiments of the present invention have been described above. Apparatus for implementing the above methods will now be provided.
