All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a structural diagram of a processing system for a random access procedure according to an embodiment of the present invention, and as shown in fig. 1, the processing system includes a terminal 11 and a base station 12, where the terminal 11 may be a ue (user equipment), for example: the terminal may be a terminal side Device such as a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), or a Wearable Device (Wearable Device), and it should be noted that the specific type of the terminal 11 is not limited in the embodiments of the present invention.

Referring to fig. 2, fig. 2 is a schematic diagram of a processing method for a random access procedure according to an embodiment of the present invention, where the method is applied to a terminal, and as shown in fig. 2, the method includes the following steps:
The relationship information may be predefined by a protocol of the terminal, predefined by the terminal and the base station, factory configured by the terminal, or the like.
The relationship information may be configured through RRC signaling by the terminal receiving base station, for example: the terminal receiving base station configures the relationship information through dedicated or broadcast RRC signaling.
The cause value may represent a cause of a random access procedure, and the cause value may include a connection establishment cause value, a reestablishment cause value, or a recovery (resume) cause value.
In addition, the connection establishment cause value may indicate a cause of a connection establishment random access procedure, the reestablishment cause value may indicate a cause of an RRC reestablishment random access procedure, and the recovery cause value may indicate a cause of an RRC recovery (resume) random access procedure. For example: the cause value may specifically be dialing an emergency number (emergency), High Priority Access (High Priority Access), called Access (mt-Access), signaling time (mo-signaling), Data transmission (mo-Data), or delay tolerant Access (delaytilerantaccess-v 1020), and the like, that is, the random Access procedure may be triggered by these causes.
The QCI may be a QCI detected by the terminal, for example: QCI of RACH, the quality of service class may be a quality of service class of the terminal. And the AC may be an access class of the random access procedure. The random access event information may indicate what random access event the random access procedure is, for example: RRC reestablishes the random access event, or RRC recovers the random access event, or SI request random access event, etc.
The attribute corresponding to the division information is an attribute corresponding to the division information in the relationship information. For example: the Priority of the random Access process with the reason value of dialing the emergency number (emergency) or High Priority Access (High Priority Access) is the first Priority (Priority 1) or the first packet (group1), and the Priority of the random Access process with the reason value of delay tolerant Access (delaytanaccess-v 1020) is the first Priority (Priority 2) or the second packet (group 2); another example is: the priority of the random access process with the AC as a first grade is a first priority or a first packet, the priority of the random access process with the AC as a second grade is a second priority or a second packet, wherein the first priority is higher than the second priority, and the level of the first packet is higher than that of the second packet.
It should be noted that, in the embodiment of the present invention, the random access procedure may be a random access procedure to be initiated by a terminal confirmation, or may also include an ongoing random access procedure, which is not limited in this embodiment of the present invention. And the random access procedure may be a contention random access procedure or a non-contention random access procedure.
The random access procedure may be a random access procedure triggered to support an initial Radio Resource Control (RRC) idle (idle) terminal UE to connect to a network, RRC reestablishment, handover, uplink data arrival but uplink out-of-sync, terminal transition from an inactive state (inactive state) to a connected state (active state), support uplink synchronization acquisition of a secondary cell (Scell), or support system information request (SI request).
And 203, processing the random access process by adopting a processing mode corresponding to the attribute.
The processing method corresponding to the attribute may be a processing method corresponding to the attribute in relationship information between the attribute and the processing method acquired by the terminal in advance, or may be a processing method estimated by the terminal according to the terminal, which is not limited in the embodiment of the present invention.
In addition, the above processing manner may be to stop the random access procedure, or may be to initiate the random access procedure by using a specific transmission parameter, and so on.
By the steps, the random access process can be processed by adopting different processing modes according to different attributes, so that the flexibility of the terminal in processing the random access process can be improved, the terminal can adapt to a flexible 5G communication system, and the access performance of the random access process can be improved, for example: for the random access process with high priority, better transmission parameters can be adopted to initiate the random access process, or when a plurality of random access processes conflict, the random access process with high priority can be preferentially ensured.
The method can be applied to a 5G system, but is not limited to the following, for example: but also to future 6G systems, etc.
In this embodiment, the relationship information between the partitioning information and the attribute, which is agreed in advance or configured by the base station through the RRC signaling, is obtained; confirming division information corresponding to a random access process, and dividing the random access process into attributes corresponding to the division information according to the relationship information, wherein the division information comprises a reason value, QCI, a service quality grade, AC or random access event information; and processing the random access process by adopting a processing mode corresponding to the attribute, so that the flexibility of the terminal in processing the random access process can be improved, and the terminal can flexibly adapt to a 5G communication system.
Referring to fig. 3, fig. 3 is a schematic diagram of a processing method for a random access procedure according to an embodiment of the present invention, where the method is applied to a terminal, and as shown in fig. 3, the method includes the following steps:
The relationship information may be predefined by a protocol of the terminal, predefined by the terminal and the base station, factory configured by the terminal, or the like.
The relationship information may be configured through RRC signaling by the terminal receiving base station, for example: the terminal receiving base station configures the relationship information through dedicated or broadcast RRC signaling.
Step 303 may be understood as processing the random access procedure by using the parameter corresponding to the attribute; or, processing the random access process by adopting a processing strategy corresponding to the attribute.
The current random access procedure includes many parameters, such as: the parameters may include power control parameters or back-off (back-off) parameters for avoiding collision, and the like, where the power control parameters may be transmission power parameters, such as: the preamble transmission power (power ramping) step length is how much the preamble transmission power per time rises, or a back off parameter for avoiding collision, etc. The backoff parameter may be a duration parameter, for example: and stopping the random access process within the time length corresponding to the backoff parameter.
In this embodiment, the terminal may configure different parameters for different attributes in advance, or relationship information between the attributes and the parameters, which is acquired by the terminal in advance, so that when the attributes of the random access procedure are determined, the corresponding parameters may be confirmed, and the random access procedure may be initiated or stopped using the parameters. Because different parameters are adopted for processing the random access process by different attributes, the flexibility of processing the random access process can be improved.
In addition, the processing policy may be obtained in advance by the terminal, for example: the embodiment of the present invention is not limited to the one generated in advance by the terminal, defined in advance by the protocol of the terminal, configured by the receiving base station, or the like. And different attributes may correspond to different processing strategies, for example: the processing strategy corresponding to the random access process with high priority is priority processing, and the processing strategy corresponding to the random access process with low priority is stop processing, wherein the stop processing is to stop processing when a plurality of random access processes collide; or, the processing strategy corresponding to the random access process with high priority is a processing strategy for initiating random access by adopting high power, and the processing strategy corresponding to the random access process with low priority is a processing strategy for initiating random access by adopting low power; or the processing strategy corresponding to the random access procedure of the specific packet is priority processing, and the processing strategy corresponding to the random access procedure of the non-specific packet is stop processing, and the like.
By the processing strategy, different processing can be performed on the random access process with different attributes, so that the flexibility of processing the random access process can be improved, and the conflict of the random access process can be avoided.
As another optional implementation manner, the processing the random access procedure by using the parameter corresponding to the attribute includes:
and confirming the power control parameters corresponding to the attributes of the random access process, and initiating the random access process by adopting the power control parameters.
The power control parameter may be configured by the terminal for the attribute in advance, or the power control parameter confirmed by the terminal according to relationship information between the attribute and the power control parameter acquired in advance, and the relationship information may be predetermined, or configured by the base station to the terminal, or may be generated by the terminal, and the like, which is not limited in the embodiment of the present invention. In addition, different attributes may correspond to different power control parameters, for example: different priorities or groups correspond to different power control parameters, so that the terminal can determine the parameters corresponding to the attributes through the relationship information. In addition, the success probability of the random access process can be improved by initiating the random access process by using the power control parameters, for example: the random access process with high priority or high grouping level can adopt high power to initiate the random access process, thereby improving the success probability of the random access process.
As another optional implementation manner, the determining division information corresponding to a random access procedure and dividing the random access procedure into attributes corresponding to the division information according to the relationship information includes:
confirming division information corresponding to at least two random access processes, and dividing each random access process into attributes corresponding to the division information thereof according to the relationship information, wherein the at least two random access processes conflict;
the processing the random access procedure by using the parameter corresponding to the attribute includes:
and confirming backoff parameters corresponding to the attributes of the at least two random access processes, and stopping at least one random access process in the at least two random access processes according to the backoff parameters.
The backoff parameter may be configured by the terminal for the attribute in advance, or the backoff parameter confirmed by the terminal according to relationship information between the attribute and the backoff parameter acquired in advance, and the relationship information may be predetermined, or configured by the base station to the terminal, or may be generated by the terminal, and the like, which is not limited in the embodiment of the present invention. In addition, different attributes may correspond to different backoff parameters, such as: different priorities or packets correspond to different back-off parameters, such as: the backoff duration of the backoff parameter corresponding to the priority 1 or the packet 1 is 0, the backoff duration of the backoff parameter corresponding to the priority 2 or the packet 2 is 2 seconds, the backoff duration of the backoff parameter corresponding to the priority 3 or the packet 3 is 5 seconds, and the like. In addition, the stopping of the at least one random access procedure may be stopping within a backoff duration corresponding to each of the at least one random access procedure, and when the backoff duration elapses, the corresponding random access procedure may be resumed. It should be noted that, if the backoff duration is 0, the corresponding random access procedure is not stopped.
Stopping the random access process according to the backoff parameters can effectively avoid the random access process collision, for example: when a plurality of random access processes of the terminal conflict, the backoff parameters can be adopted to stop some random access processes, so that the conflict of the random access processes can be avoided, and the random access performance of the terminal is improved.
As another optional implementation manner, the determining division information corresponding to a random access procedure and dividing the random access procedure into attributes corresponding to the division information according to the relationship information includes:
confirming division information corresponding to at least two random access processes, and dividing each random access process into attributes corresponding to the division information thereof according to the relationship information, wherein the at least two random access processes conflict;
the processing the random access process by adopting the processing strategy corresponding to the attribute comprises:
selecting a random access procedure with the highest level of the attribute or a random access procedure of a specific group in the at least two random access procedures, maintaining or initiating the selected random access procedure, and stopping other random access procedures except the selected random access procedure.
The random access procedure with the highest level may be the random access procedure with the highest priority, and the random access procedure of the specific packet may be a pre-specified packet, for example: packet 1, or each packet is divided into corresponding levels, and the specific packet may be the highest level packet.
For example: the terminal may initiate a random access procedure for establishing an RRC connection in a random access procedure in which the terminal initiates an SI request, so that the terminal may implement only one random access procedure through the above steps, where, for example, an attribute of the random access procedure for the SI request is a second priority (priority 2) or a second grouping (group2), and when an attribute of the random access procedure for establishing an RRC connection is a first priority or a first grouping, an RRC layer of the terminal indicates to stop the random access procedure for the SI request to perform the random access procedure for establishing an RRC connection; when the attribute of the random access process of the RRC connection establishment is a third priority or a third packet, the terminal RRC layer instructs to stop the random access process of the RRC connection establishment and to maintain or initiate (or understand as performing) the random access process of the SI request.
In the embodiment, the steps can effectively avoid the conflict of the random access process, and can ensure the random access process with high level, thereby improving the performance of the random access of the terminal.
In this embodiment, various optional embodiments are added on the basis of the embodiment shown in fig. 2, and the flexibility of the terminal in processing the random access process can be improved, so that the terminal can flexibly adapt to a 5G communication system.
