In order to make readers clearly understand differences in technical solutions and technical effects of the random access method in the embodiments of the present application compared with the random access method in the related art, and avoid tedious redundancy, in the embodiments of the present application, a scenario in which a terminal device is a User Equipment (UE), a network device is a base station, and the User Equipment is switched between a source base station and a target base station is taken as an example (specifically, refer to a system block diagram shown in fig. 1), and is explained in detail.
As shown in fig. 1, when the user equipment moves from a left position to a right position, the network quality of the user equipment accessing to the source base station is relatively high before the user equipment moves, i.e., when the user equipment is in the left position, and the network quality of the user equipment accessing to the target base station is relatively high when the user equipment is in the right position, i.e., after the user equipment moves, therefore, the user equipment can access to the target base station based on random access to improve the network quality after moving.
The method of random access implemented based on the system shown in fig. 1 will now be described in detail with reference to fig. 2.
As shown in fig. 2, the method for random access includes:
s101: the source base station transmits RRC Connection Reconfiguration information (RRC Connection Reconfiguration) including Measurement Configuration information (Measurement Configuration) to the user equipment.
Correspondingly, the user equipment receives the RRC connection reconfiguration information sent by the source base station.
The measurement configuration information is used to instruct the ue to measure the neighboring cells, such as Reference Signal Receiving Power (RSRP). The reference signal received power is one of key parameters that can represent the wireless signal strength in the LTE network and the physical layer measurement requirement.
S102: the user equipment transmits a Measurement report (Measurement Reports) obtained and generated based on the RRC connection reconfiguration information to the source base station.
Accordingly, the source base station receives the measurement report sent by the user equipment.
That is, the user equipment may measure the neighboring cell based on the RRC connection reconfiguration information, generate and transmit a measurement report including a measurement result to the source base station, when receiving the RRC connection reconfiguration information transmitted by the source base station.
S103: the source base station generates a Handover decision (Handover decision).
For example, the handover decision may be generated if the source base station determines that the network performance of the ue accessing the target base station is relatively better based on the measurement report.
S104: the source base station sends a Handover Request (Handover Request) to the target base station.
Correspondingly, the target base station receives the switching request sent by the source base station.
S105: the target base station determines to admit the handover of the user equipment based on Admission Control (Admission Control) and the handover request.
S106: the target base station transmits a Handover Request acknowledgement (Handover Request Ack) to the source base station.
Correspondingly, the source base station receives the switching request response sent by the target base station.
S107: the source base station transmits RRC connection reconfiguration information to the user equipment, the RRC connection reconfiguration information including Mobility Control information (Mobility Control).
Correspondingly, the user equipment receives the mobility control information sent by the source base station.
In this step, the mobility control information includes the relevant information of the target base station, and the source base station sends the relevant information of the target base station to the user equipment, so that the user equipment accesses to the target base station based on the relevant information of the target base station.
S108: and the user equipment and the target base station finish random access.
S109: and the user equipment sends an RRC connection reconfiguration information completion message to the target base station, wherein the RRC connection reconfiguration information completion message is used for representing that the user equipment completes the configuration of the relevant information of the target base station.
Correspondingly, the target base station receives the RRC connection reconfiguration message completion message sent by the user equipment.
S110: and the target base station completes the path switching.
Specifically, the target base station and a Serving Gateway (Serving Gateway) complete path switching.
S111: the target base station sends a message for releasing the Context of the user equipment (UE Context Release) to the source base station.
Correspondingly, the source base station receives the message of the user equipment context sent by the target base station.
S112: the source base station releases the resources (Release resources) of the user equipment.
It should be noted that the Physical Random Access Channel (PRACH) and the Physical Uplink Shared Channel (PUSCH) have a multiplexing function, that is, the Physical random Access Channel and the Physical Uplink Shared Channel also have a multiplexing function during the random Access of the ue.
However, since the physical random access channel and the physical uplink shared channel have a multiplexing function, when the user equipment performs random access, the performance of the demodulation function of the physical random access channel may be degraded, thereby causing a problem that the user equipment fails random access or delays random access.
The inventor of the present application has obtained the inventive concept of the present application after creative efforts: when the user equipment is accessed randomly, the multiplexing function of the physical random access channel and the physical uplink shared channel is suspended.
The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
According to an aspect of the embodiments of the present application, the embodiments of the present application provide a method for random access, which may be applied to an application scenario as shown in fig. 1, and may also be applied to other application scenarios as listed in the above embodiments, and so on.
Referring to fig. 3, fig. 3 is a flowchart illustrating a method for random access according to another embodiment of the present application.
As shown in fig. 3, the method includes:
s201: and if the network equipment receives the random access request, the multiplexing function of using the physical random access channel and the physical uplink shared channel is suspended.
The execution main body of this embodiment may be a network device, and for the description of the network device, reference may be made to the above embodiments, which are not described herein again.
In connection with the embodiment shown in fig. 1, the network device may be a target base station.
In connection with the embodiment shown in fig. 2, the request for random access received by the network device (i.e., the target base station) may be a request for random access triggered based on a handover request initiated by the source base station. For example, in S108, the user equipment may initiate a request for random access to the target base station, so that the user equipment and the target base station complete random access.
S202: the network device performs random access based on the physical random access channel that suspends use of the multiplexing function.
In connection with the embodiment shown in fig. 1, after suspending the multiplexing function of using the physical random access channel and the physical uplink shared channel, the network device (i.e., the target base station) may perform random access based on the physical random access channel for which the multiplexing function is suspended.
In conjunction with the embodiment shown in fig. 2, in S108, the ue may initiate a request for random access to the target base station, the target base station may suspend the multiplexing function of the physical random access channel and the physical uplink shared channel, and the target base station and the ue perform random access based on the physical random access channel on which the multiplexing function is suspended.
Based on the above analysis, in the process of performing random access by the ue and the network device, in the related art, the physical random access channel and the physical uplink shared channel have a multiplexing function, and therefore, when the physical random access channel is used for performing random access, the physical random access channel is also used for data transmission and other operations of other ues, which may cause performance degradation of a demodulation function of the physical random access channel, and further cause a problem of a failure of random access of the ue or a large delay of random access.
In this embodiment, when the network device receives the request for random access, the use of the multiplexing function of the physical random access channel and the physical uplink shared channel is suspended, so that the physical random access channel is used to support random access, thereby avoiding the problem of performance degradation or large delay of the demodulation function of the physical random access channel due to the multiplexing function in the related art, and further achieving the technical effects of improving the efficiency and reliability of random access and improving the throughput.
S203: if the random access is finished, the network equipment recovers the multiplexing function of using the physical random access channel and the physical uplink shared channel.
That is, if the random access is completed, the network device recovers the multiplexing function of using the physical random access channel and the physical uplink shared channel, so as to fully utilize the channel resources of the physical random access channel, thereby improving the technical effect of resource utilization.
Based on the foregoing analysis, an embodiment of the present application provides a method for random access, where the method is applied to a network device, and includes: if a request of random access is received, the multiplexing function of the physical random access channel and the physical uplink shared channel is paused, random access is executed based on the physical random access channel of which the multiplexing function is paused, if the random access is completed, the multiplexing function of the physical random access channel and the physical uplink shared channel is resumed, and the problem that the performance of the demodulation function of the physical random access channel is reduced or the delay is large due to the multiplexing function in the related technology can be avoided by executing the random access based on the physical random access channel of which the multiplexing function is paused, so that the technical effects of improving the efficiency and the reliability of the random access and improving the throughput are realized.
In some embodiments, whether the physical random access channel and the physical uplink shared channel are allowed to be distinguished by using the multiplexing function may be determined by setting a multiplexing flag, and for the reader to understand the implementation principle more deeply, the detailed description will be made with reference to fig. 4. Fig. 4 is a flowchart illustrating a random access method according to another embodiment of the present application.
As shown in fig. 4, the method includes:
s301: the network equipment configures multiplexing zone bits for the multiplexing function of the physical random access channel and the physical uplink shared channel.
S302: if the network equipment receives the random access request, the multiplexing zone bit of the multiplexing function of the physical random access channel and the physical uplink shared channel is set as a first zone.
The first flag is used for indicating that the multiplexing function of the physical random access channel and the physical uplink shared channel is suspended, that is, the physical random access channel and the physical uplink shared channel are not multiplexed.
S303: the network device performs random access based on the physical random access channel that suspends use of the multiplexing function.
For the description of S303, reference may be made to S202, which is not described herein again.
S304: and if the random access is finished, the network equipment sets the multiplexing zone bit as a second zone.
The second flag is used to indicate that the multiplexing function of the physical random access channel and the physical uplink shared channel is recovered, that is, multiplexing of the physical random access channel and the physical uplink shared channel is allowed.
In some embodiments, the first flag and the second flag may be represented by different numerical values, such as:
if the first flag is 0, the second flag is 1; if the first flag is 1, the second flag is 0.
Of course, in other embodiments, the first mark and the second mark may also be represented by different characters, and the like.
It should be noted that, in some embodiments, the network device may perform initialization setting on the multiplexing flag after the multiplexing flag configuring the multiplexing function of the physical random access channel and the physical uplink shared channel (i.e., after S301 and before S302), and may set the multiplexing flag to the second flag during initialization setting, that is, during initialization setting, multiplexing of the physical random access channel and the physical uplink shared channel is allowed, and when random access needs to be performed, multiplexing of the physical random access channel and the physical uplink shared channel is suspended.
And based on the above analysis, in some embodiments, the random access request includes at least one of:
a random access request triggered by a network device handover;
random access request triggered by uplink out-of-step;
due to the arrival of the downlink data at the triggered random access request.
According to another aspect of the embodiments of the present application, a network device is further provided in the embodiments of the present application, for implementing the method for random access shown in fig. 3 or fig. 4.
Referring to fig. 5, fig. 5 is a schematic diagram of a network device according to an embodiment of the present application.

a suspending module 11, configured to suspend, if a request for random access is received, a multiplexing function of a physical random access channel and a physical uplink shared channel;
an executing module 12, configured to execute random access based on the physical random access channel for which the multiplexing function is suspended;
a recovering module 13, configured to recover, if the random access is completed, the multiplexing function of using the physical random access channel and the physical uplink shared channel.
In some embodiments, the multiplexing function of suspending and resuming the use of the physical random access channel and the physical uplink shared channel is set by setting a multiplexing flag bit.
In some embodiments, the suspending module 11 is configured to set a multiplexing flag bit of a multiplexing function of the physical random access channel and the physical uplink shared channel to a first flag, where the first flag is used to indicate that the multiplexing function of the physical random access channel and the physical uplink shared channel is suspended;
