Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
As shown in fig. 1, an embodiment of the present invention provides a method for communication access, which is applied to a terminal, and the method includes:
step 11, acquiring at least one group of access configuration parameters configured by the network equipment and an access type corresponding to each group of access configuration parameters; the access configuration parameters include multiple groups, such as a first configuration parameter, a second configuration parameter, and the like, each group of configuration parameters corresponds to an access type, and the access type may include, for example, a first access type and a second access type. The first access type uses a first configuration parameter, and the second access type uses a second configuration parameter; the access with the specific access type higher priority is realized by configuring the corresponding priority access parameter for the specific access type;
and step 13, initiating an access flow according to the selected access configuration parameters.
The embodiment of the invention obtains at least one group of access configuration parameters configured by the network equipment and the access type corresponding to each group of access configuration parameters; according to the access type of the initiated service, selecting access configuration parameters corresponding to the access type from the at least one group of access configuration parameters; initiating an access flow according to the selected access configuration parameters; realize the differentiated access to different services or terminals and provide differentiated communication service for higher-priority services or UE
In an optional embodiment of the present invention, the access configuration parameter includes at least one of the following:
randomly accessing a power lifting step length; a back-off scaling factor; a random access type indication; two-step random access backoff times; and fourthly, randomly accessing the backoff times.
In an optional embodiment of the present invention, the random access power ramping step is used to calculate a preamble reception target power, and a specific value may be 0dB, 2dB, 4dB, or 6 dB; when the terminal accesses randomly, it may receive a back-off indication from the network side, and the terminal needs to back off and wait for a period of time and then initiate random access again, and when initiating again, the terminal uses the random access power raising step length to raise the power, for example, if the step length is configured to 4dB, when the terminal retransmits the random access, the power is raised by 4dB, so as to obtain high access possibility.
The backspacing scaling factor is used for calculating backspacing time, and the specific value can be 0, 0.25, 0.5 or 0.75; when the terminal accesses randomly, the terminal receives a back-off instruction from the network side, and the terminal determines the back-off waiting time according to the back-off scaling factor and the back-off instruction. The smaller the back-off scaling factor value, the shorter the waiting time is required. For example, the backoff wait time may be derived by multiplying the backoff scaling factor by the backoff time.
The random access type indication is used for indicating that the corresponding access type is two-step random access or four-step random access; the information carried is a two-step random access indication or a four-step random access indication.
The two-step random access indication is used for indicating that the random access triggered by the access type adopts two-step random access. Compared with four steps, the two-step random access has shorter time delay, can access a network more quickly, and is more suitable for high-priority services.
The four-step random access indication is used for indicating that the random access triggered by the access type adopts four-step random access.
The two-step random access backoff times are the maximum backoff times of the terminal for two-step random access when the access type is two-step random access; when the maximum number is exceeded, the terminal should fall back to four-step random access.
And the four-step random access backoff times are the maximum backoff times of the terminal for performing the four-step random access when the access type is the four-step random access. The four-step random access backoff number refers to the maximum backoff number of the four-step random access performed by the terminal when the access category corresponds to the four-step random access, and the radio link failure process is triggered when the maximum backoff number exceeds the maximum backoff number.
In an optional embodiment of the present invention, the access type includes at least one of the following:
an access category (access category); access id (access identity); cause value (cause value); slice (slice).
In an optional embodiment of the present invention, the access category is information associated with a service, which is acquired by a radio resource control RRC layer of the terminal from a non-access NAS layer; for example, some APPs may be mapped to a particular access category.
The access ID is information associated with a user SIM card; for example, the user's SIM card may belong to any one or several of the access IDs 1-15, and similarly the users are grouped into 15 groups, for example, a gold user belongs to access IDs 1 and 12.
The reason value is the reason for initiating random access;
the slice is a slice initiating an access request.
In an optional embodiment of the present invention, the reason for initiating the random access includes at least one of the following:
emergency calls (emergency); high priority access (highPriorityAccess); a terminal called Access (mt-Access); terminal-originating signaling (mo-signaling); terminal caller Data (mo-Data); a terminal caller voice call (mo-VoiceCall); a terminal caller video call (mo-VideoCall); a terminal caller short message (mo-SMS); alarm information; and (4) safety information.
In an optional embodiment of the present invention, the slice for initiating the access request may be:
the method comprises the following steps of enhancing mobile broadband eMBB slices, ultra-reliable low-delay communication URLLC slices, large-scale Internet of things service mMTC slices or other slices.
The following describes a specific implementation process of the above method with reference to a specific embodiment: the network side sends configuration information, i.e., configuration parameter 1 corresponding to slice 1, i.e., configuration parameter 1 applied to random access of slice 1, and configuration parameter 2 corresponding to slice 2, to the terminal. When the terminal initiates random access of slice 1, configuration parameter 1 is adopted, where the configuration parameter 1 may include at least one of a random access power increase step length, a backoff scaling factor, a four-step random access indication, or four-step backoff times shown in the following table. .
The terminal initiates random access due to the triggering of a certain service or reason value, receives a backspacing indication sent by a network side, and calculates the actual backspacing time by combining a backspacing scaling factor corresponding to the service or reason value to perform backspacing. After the backoff time is overtime, the terminal raises the power according to the random access power raising step length corresponding to the service or the reason value to initiate random access again.
The network broadcasts the following information:
and the terminal receives the configuration information, and selects corresponding access configuration parameters according to the initiated access type. When a terminal initiates an access request of a slice 1, a configuration parameter 1 is used for initiating four-step random access, when the random access is backed off, the back-off time is calculated according to a back-off scaling factor 0.75 and a back-off instruction sent by a network side, after the back-off time is waited for in a back-off mode, the power is raised by 2dB, and a lead code is sent again. When the rollback reaches 5 times, a radio link failure process is triggered.
When a terminal initiates an access request of a slice 2, a configuration parameter 2 is used, namely, two-step random access is initiated, when the random access is backed off, the back-off time is calculated according to a back-off scaling factor of 0.25 and a back-off instruction sent by a network side, after the back-off time is waited for in a back-off mode, the power is raised by 6dB, and a lead code is initiated again. When the number of times of the two-step random access backoff reaches 3 times, the terminal will back to the four-step random access, that is, the four-step random access will be adopted when the random access is initiated again.
Thereby realizing the differential priority access of different access types.
The access ID is used for distinguishing users, each terminal may belong to 1 or more access IDs, and a higher access probability of partial vip users is achieved by configuring a higher access power increasing step size and a shorter backoff scaling factor for partial access IDs.
While the other access types mentioned above, such as slice, access category, cause value, access ID, are all traffic differentiated types.
The method according to the above embodiment of the present invention configures different configuration parameters for different access types to implement differentiated backoff and power boost when a random access collision occurs.
In the above scheme of the present invention, the network side sends at least one set of configuration parameters and access types suitable for the configuration parameters to the terminal, that is, each access type corresponds to a set of configuration parameters. The configuration parameters include at least one of: the method comprises the steps of random access power lifting step length, backspacing scaling factors, random access type indication, two-step random access backspacing times and four-step random access backspacing times. The access type may be at least one of: access category (access category), access id (access identity), cause value (cause value), slice (slice). After receiving the parameters, the terminal selects the access configuration parameters corresponding to the access category according to the access category to which the initiated service belongs before initiating the service, and initiates random access. Therefore, the priority of the terminal or the service can be distinguished, differentiated random access service is provided, higher power rise or lower back-off time is provided for the service with high priority, and the probability of random access conflict can be reduced.
Here, the slices, the access categories, and the terminals are prioritized to provide a higher priority service for high priority traffic or users, i.e., to ensure that the high priority slices have a larger step size for lifting and a shorter back-off time.
When multiple terminals send the same preamble at the same time, random access collision occurs, and at this time, the network side only issues a backoff time through MSG 2, and the terminals are likely to collide when retransmitting. After the scheme of the invention is used, different configuration parameters, namely different backspacing scaling factors, are adopted according to different access types for initiating random access, so that a plurality of terminals of different slices can be fully dispersed in time, and the conflict is avoided when random access is initiated again. The probability of collisions is reduced.
The scheme of the invention can also configure different services into two-step or four-step random access, thereby further avoiding interference. For example, the high-priority service is configured as two-step random access, and the low-priority service is configured as four-step random access, so that the low-priority service is prevented from seizing the MSG a resource of the high-priority service.
