Description
Technical Field
The invention relates to the field of private network communication, in particular to a method, a system and equipment for reserving a response time slot.
Background
A service process of a Digital Mobile Radio (DMR) system or a Police Digital Trunking (PDT) system generally includes that a Mobile Station (MS) waits on a control Channel, the control Channel performs Channel access management by issuing a random access invitation signaling and a Common broadcast Channel (CACH), and the MS applies for a service or sends a response to a service request according to a busy state of the Channel.
In general, a Base Station (BS) reserves a response time slot for an MS that needs to send a service request response, and specifically, sets the time slot that needs to send the service request response to a busy state in advance, so that only a designated MS can use the time slot.
Currently, in DMR/PDT standard, the BS is reserved by default in the next uplink timeslot when the MS receives the service request, as shown in fig. 1, the MS1 receives the service request from the BS in the B position, and the base station will reserve the At bit position 1 of the next uplink timeslot to the MS1 for responding to the service request. The value of At bit is judged before other random access terminals MSx initiate service request to BS, so as to obtain the busy state of time slot, and backoff is performed if the time slot is busy. In this way it is ensured that the time slot is only used for the transmission of service request acknowledgements by the MS 1.
When the MS receives the service request from the BS, it usually completes the response of the service request in the next uplink timeslot, but since one timeslot in the DMR/PDT system is generally 30MS, that is, the MS needs to complete a series of processes of decoding, parsing, preparing modulation data, encoding and retransmitting, etc. related to the response within 30MS, it obviously has a high requirement on the operating frequency of the CPU of the MS.
In addition, for the MS, the issuing time of the service request from the BS is random, and if the MS is required to complete the series of processing within one time slot, that is, 30MS, the MS is required to operate at a higher frequency all the time, and once the service request needs to be answered, the series of processing related to the answering can be completed in time, which obviously increases the operating power consumption of the MS.

Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. 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 application.
The DMR/PDT standard uses a Time Division Multiple Access (TDMA) frame structure with two Time slots, as shown in fig. 2, one TDMA frame includes 2 Time slots, each Time slot is 30MS, and the TDMA frame is divided into two directions, namely an uplink (MS TX) direction and a downlink (BS TX) direction, where CACH signaling is set between the two Time slots in the BS TX direction, the CACH signaling is a common broadcast channel, and is sent between the two downlink Time slots, mainly used for channel management and access control, and carries some low-speed signaling. An Access Type (AT) is used as a field in the CACH signaling to indicate an available state of a next uplink timeslot, where the AT is 0 to indicate that the next uplink timeslot is in an idle available state, and the AT is 1 to indicate that the available state of the next uplink timeslot is in a busy unavailable state.
Currently, the base station will reserve the next uplink timeslot for sending the service request to the mobile station as the response timeslot of the mobile station for the service request. The specific implementation is to set the AT after the uplink timeslot for sending the service request to 1, so that the next uplink timeslot is only used by the mobile station. That is, the mobile station needs to complete the response to the service request in the reserved time slot, i.e., complete a series of processes of decoding, parsing, preparing modulated data, encoding and retransmitting, which are involved in the response. However, since the time for issuing the service request from the base station is random for the mobile station, if the mobile station is required to complete the response to the service request in the reserved time slot, the mobile station needs to operate at a higher frequency all the time, and once the response to the service request needs to be performed, a series of processing related to the response can be completed in time, which obviously increases the operation power consumption of the mobile station.
Therefore, the embodiment of the invention provides a method for reserving a response time slot, which is characterized in that a time slot reservation strategy is predetermined between a base station and a mobile station, so that the mobile station already knows the response time slot of a service request clearly before the base station sends the service request, and therefore, the mobile station can adjust the running frequency of a CPU to the running frequency matched with the processing capacity of the CPU in advance, so that when the response time slot arrives, the running frequency of the CPU required by a series of processing related to response can be timely completed, the response processing can be ensured to be completed in the response time slot, and meanwhile, the mobile station is not required to run at a higher frequency all the time, and the running power consumption of the mobile station is reduced.
To further explain the above, an embodiment of the present invention provides a flowchart of a method for reserving a response time slot, and referring to fig. 3, specifically, the method for reserving a response time slot includes:
s301: the base station determines a time slot reservation strategy corresponding to the mobile station; wherein the time slot reservation strategy is used for indicating the time slot position of the mobile station for response.
In practical application, the base station predetermines a time slot reservation policy corresponding to the mobile station, that is, a time slot position where the mobile station responds is predetermined. Specifically, the base station may determine a time slot reservation policy corresponding to the mobile station according to the current system service status and the processing capability of the mobile station. The time slot reservation strategy can indicate the time slot position of the mobile station to respond by indicating a certain time slot position or certain time slot positions after the service request is sent to respond.
Different mobile stations can have the same time slot reservation strategy, or different mobile stations can also have different time slot reservation strategies, specifically, the time slot reservation strategy can be that a certain uplink time slot after the base station sends the service request carries out the response of the service request; or the base station may respond to the service request in some uplink timeslots after sending the service request.
In addition, the time slot reservation policy may also be used to indicate the number of time slots for the mobile station to respond to, that is, the mobile station may utilize multiple time slots to respond to the service request, for example, several uplink time slots after the base station sends the service request.
S302: and the base station sends the time slot reservation strategy to the mobile station.
In practical application, after the base station determines the time slot reservation strategy corresponding to the mobile station in advance, the time slot reservation strategy is notified to the mobile station, so that the mobile station can definitely perform the response time slot of the service request before the base station sends the service request.
In one implementation, the base station transmits the determined slot reservation policy to the corresponding mobile station by extending any one downlink instruction. Specifically, the base station may send the determined timeslot reservation policy to the corresponding mobile station by extending downlink CSBK (Control signaling Block) signaling, so as to notify the mobile station to respond in the timeslot specified by the timeslot reservation policy.
S303: and the mobile station adjusts the CPU operation frequency according to the time slot reservation strategy and responds the service request at the time slot position.
Since the mobile station knows the response time slot of the service request through the reserved time slot strategy before the base station sends the service request, the mobile station can adjust the running frequency of the CPU in advance according to the reserved time slot strategy before the response time slot arrives, so that the running frequency of the mobile station reaches the running frequency of a series of operations of processing all decoding, analyzing, preparing modulation data, coding, transtransmitting and the like related to response when the response time slot arrives. In addition, after the mobile station determines the time slot reservation strategy, the mobile station can respond to the subsequent various service requests according to the time slot reservation strategy, and only after the mobile station receives the time slot reservation strategy from the base station again, the mobile station can respond to the service requests according to the new time slot reservation strategy.
In addition, after determining the time slot reservation strategy corresponding to the mobile station, the base station works based on the time slot reservation strategy corresponding to each mobile station. In one implementation, after sending a service request to be responded to a mobile station, a base station indicates that the time slot is only used for the mobile station to respond to At bit position 1 corresponding to a response time slot indicated in a corresponding time slot reservation policy.
In the method for reserving a response time slot provided by the embodiment of the invention, a base station determines a time slot reservation strategy corresponding to a mobile station in advance, and sends the time slot reservation strategy to the mobile station, so that the mobile station adjusts the CPU operating frequency according to the time slot reservation strategy and responds at the time slot position. In the invention, before the base station sends the service request, the mobile station already definitely knows the response time slot of the service request through a time slot reservation strategy, so that the mobile station can adjust the CPU operation frequency to the operation frequency matched with the processing capability of the CPU in advance, so that when the response time slot is reached, the CPU operation frequency required by a series of processing related to response can be timely completed, the response processing is ensured to be completed in the response time slot, meanwhile, the mobile station is not required to be always operated at a higher frequency, and the operation power consumption of the mobile station is reduced.
In an application scenario, a mobile station can actively apply for a time slot reservation policy to a base station at any time, and after the time slot reservation policy is determined by the mobile station and the base station, the mobile station and the base station need to complete synchronization of the time slot reservation policy. Specifically, referring to fig. 4, an interaction diagram of a response slot reservation method provided in an embodiment of the present invention is shown, where the method includes:
s401: the mobile station sends a time slot reservation request to the base station, wherein the time slot reservation request is used for requesting to determine a time slot reservation strategy.
In practical application, the mobile station may send a time slot reservation request to the base station by extending any uplink signaling, so as to request the base station to determine a time slot reservation policy, and specifically, may send a time slot reservation request to the base station by extending uplink CSBK signaling.
S402: the base station determines and sends a time slot reservation strategy corresponding to the mobile station; wherein the time slot reservation strategy is used for indicating the time slot position of the mobile station for response.
In practical application, after receiving a time slot reservation request from a mobile station, a base station may determine a time slot reservation policy corresponding to the mobile station according to a current system service condition. In addition, if the time slot reservation request carries the time slot position requested to be reserved by the mobile station, the base station can also determine whether the time slot position is feasible, if so, the base station determines a time slot reservation strategy according to the time slot position requested to be reserved by the mobile station, and sends the determined time slot reservation strategy to the mobile station.
S403: and the mobile station adjusts the CPU operation frequency according to the time slot reservation strategy.
Before the base station sends a service request to the mobile station, the mobile station adjusts the CPU operation frequency in advance according to the position of the response time slot appointed in the time slot reservation strategy, so that the operation frequency can meet the requirements of a series of processing related to response after the appointed response time slot is reached.
S404: the base station sends a service request to the mobile station.
S405: the mobile station replies to the service request at the time slot position specified by the time slot reservation strategy.
Since the mobile station already knows the slot position where the response is made before the service request is sent, the mobile station adjusts the CPU operating frequency in advance before the response slot is reached, so that a series of processing involved in the response is completed at the accurate slot position.
In the response time slot reservation method provided by the embodiment of the invention, each mobile station can actively apply for a time slot reservation strategy so as to acquire the time slot position of the response of the service request in advance and adjust the running frequency of the CPU, when the response time slot arrives, the running frequency of the CPU required by a series of processing related to the response can be timely completed, the response processing is ensured to be completed in the response time slot, meanwhile, the mobile station is not required to run at a higher frequency all the time, and the running power consumption of the mobile station is reduced.
In another application scenario, the base station may initiate the adjustment of the time slot reservation policy at any time, and after the mobile station and the base station define the time slot reservation policy, the mobile station and the base station need to complete the synchronization of the time slot reservation policy. Specifically, referring to fig. 5, an interaction diagram of another response slot reservation method provided in the embodiment of the present invention is shown, where the method includes:
s501: and the base station determines a time slot reservation strategy corresponding to the mobile station according to the current system service condition.
In practical application, the base station may determine the time slot reservation policy corresponding to each mobile station according to the current system service status. Specifically, when the base station needs to send a service request requiring a response, it needs to first determine a time slot reservation policy corresponding to the mobile station receiving the service request.
S502: the base station sends the slot reservation policy to the mobile station.
S503: the mobile station acknowledges the slot reservation policy.
In practical applications, after receiving the slot reservation policy from the base station, the mobile station may acknowledge the slot reservation policy to inform the base station that the mobile station is synchronized with the base station.
In a specific implementation manner, each mobile station may be configured with the same time slot reservation policy, and the base station may uniformly transmit the time slot reservation policy to the mobile stations configured with the same time slot reservation policy through extended broadcast signaling at the same time. In this case, after receiving the slot reservation policy, each mobile station may or may not perform acknowledgement respectively for the slot reservation policy, and the specific implementation scheme is not limited herein.
In another specific implementation, each mobile station may be configured with a different slot reservation policy, and for this case, each mobile station may acknowledge the received slot reservation policy to inform the base station that the mobile station has synchronized with the base station. In addition, each mobile station may not perform acknowledgement, and the specific implementation scheme is not limited herein.
S504: and the mobile station adjusts the CPU operation frequency according to the time slot reservation strategy.
S505: the base station sends a service request to the mobile station.
S506: the mobile station replies to the service request at the time slot position specified by the time slot reservation strategy.
