Description
Technical Field
The present invention relates to the field of communications, and in particular, to a method and an apparatus for determining a resource, a storage medium, and an electronic apparatus.
Background
With the rapid development of mobile broadband, more and more Long-Term Evolution (LTE) networks are deployed on the 900MHz and 1800MHz spectrums. The 1800MHz frequency band is currently the mainstream frequency band deployed in the LTE network, and the frequency band simultaneously carries a large amount of Global system for Mobile Communication (GSM) services, so when an operator deploys the LTE network, a part of the GSM frequency band needs to be re-duplicated (i.e., reallocated) to LTE. Common spectrum allocation modes among networks of different systems are classified into static spectrum allocation and dynamic spectrum allocation. Static spectrum allocation is to statically cut a part of spectrum occupied by GSM into LTE, the part of spectrum can only be used by LTE, GSM can not be used all the time, congestion occurs when GSM telephone traffic is increased, and the spectrum utilization rate is low; because the GSM traffic load is dynamically changed, the number of occupied carrier frequencies is large when the traffic is high, and the number of occupied carrier frequencies is small when the traffic is low, if the spectrum resources can be dynamically allocated between GSM and LTE according to the number of occupied carrier frequencies of GSM, it is called dynamic spectrum sharing. At present, the common dynamic spectrum sharing granularity between the GSM and the LTE is at the GSM carrier level, that is, once the GSM carrier frequency is occupied, the LTE cannot be used, and only after the GSM carrier frequency is released, the spectrum resource occupied by the corresponding GSM carrier frequency can be released to the LTE.
Because GSM is a narrow-band Time Division Multiple Access (TDMA) system, a GSM carrier frequency bandwidth is 200Khz, a basic frame in each carrier frequency Time domain includes 8 Time slots, a GSM voice occupies one Time slot, a data service occupies Multiple Time slots, the number and position of activated Time slots on each GSM carrier are allocated by a Base Station Controller (BSC), when there is still an idle Time slot not fully occupied by a Time slot on a GSM carrier, LTE cannot schedule using the idle Time slot on the GSM carrier frequency, and therefore, there is a problem of low resource utilization.
In view of the above problems in the related art, no effective solution has been proposed.

Detailed Description
The invention will be described in detail hereinafter with reference to the accompanying drawings in conjunction with embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.
In this embodiment, a method for determining a resource is provided, and fig. 1 is a flowchart of a method for determining a resource according to an embodiment of the present invention, as shown in fig. 1, the flowchart includes the following steps:

step S104, acquiring a time slot coordination frame synchronization signal generated by the GSM module;
step S106, determining the target resource allowed to be used by the LTE module in the resource bitmap matrix based on the time slot coordinated frame synchronization signal.
The LTE module may perform the above operations. In the above embodiment, when the LTE module obtains the resource bitmap matrix, the LTE module may obtain the resource bitmap matrix through the timeslot cooperative control unit, that is, the timeslot cooperative control unit may obtain, from the GSM module, a time-frequency domain resource occupancy bitmap matrix of a GSM carrier frequency currently being used, and send the time-frequency domain resource occupancy bitmap matrix to the LTE module. In addition, the GSM module may periodically generate a timeslot coordinate frame synchronization signal and notify the LTE module in a specific manner (for example, by means of an interrupt signal), and after the LTE module acquires the timeslot coordinate frame synchronization signal, the LTE scheduler may automatically calculate the RB resource location of the resource block that can be used at each scheduling time according to the resource bitmap matrix.
In the above embodiment, it can be determined that the time-frequency domain resource of the GSM carrier frequency used by the GSM module occupies the target resource allowed to be used by the LTE module in the bitmap matrix, so that the purpose of GSM and LTE dynamic spectrum sharing can be achieved, the problem of low resource utilization rate in the related art is solved, and the purpose of greatly improving the spectrum sharing efficiency is achieved.
In an optional embodiment, the GSM module may notify the LTE module of the timeslot coordinate frame synchronization signal generated periodically by using an interrupt signal, and correspondingly, in this case, acquiring the timeslot coordinate frame synchronization signal generated by the GSM module includes: and acquiring the time slot cooperative frame synchronization signal based on an interrupt signal triggered by the GSM module.
In an optional embodiment, acquiring the timeslot cooperative frame synchronization signal based on the interrupt signal triggered by the GSM module includes: periodically triggering frame interruption of an LTE system frame, and reading GSM time slot cooperative frame number information in a GSM module at a first interruption moment of frame interruption, wherein the GSM time slot cooperative frame number information is TDMA frame number information of a corresponding time slot cooperative frame written into a target storage module by the GSM module at a second interruption moment, and the second interruption moment is an interruption moment corresponding to an interruption signal of the time slot cooperative frame triggered at a frame header moment of a synchronous periodic signal after the GSM module generates a GSM time slot cooperative frame synchronous periodic signal; and when the current read GSM time slot cooperative frame number information is determined to be different from the GSM time slot cooperative frame number information read last time, determining the current time as the starting time of the time slot cooperative frame synchronization signal. In this embodiment, the GSM timeslot coordinate frame synchronization signal generation and interruption triggering unit on the GSM side is responsible for generating a GSM timeslot coordinate frame synchronization periodic signal (the period is 60ms or an integer multiple of 60 ms), triggering a timeslot coordinate frame interruption signal at the frame header time of the frame synchronization signal, and writing TDMA frame number information of a corresponding timeslot coordinate frame into the GSM timeslot coordinate frame interruption information storage unit on the GSM side at each interruption time; the LTE system frame interruption triggering unit at the LTE side triggers the LTE system frame interruption periodically (for example, every 10ms), reads the GSM time slot cooperative frame number information in the GSM time slot cooperative frame interruption information storage unit at the interruption time, and if the frame number is found to change relative to the frame number information read at the previous interruption time, the moment is the starting moment of a GSM time slot cooperative frame synchronization periodic signal, and the LTE module takes the moment as the starting moment of a time slot cooperative scheduling calculation counter. The phase synchronization unit between the LTE module and the GSM module is used for ensuring the clock behavior synchronization of the LTE module and the GSM module, and the unit can be a GPS clock source, a Beidou or Glonass GLONSS clock source.
In an optional embodiment, after determining, based on the timeslot cooperative frame synchronization signal, a target resource allowed to be used by a long term evolution LTE module in the resource bitmap matrix, the method further includes: and feeding back a cooperative scheduling starting execution confirmation message to the GSM module to indicate the GSM module to perform resource scheduling according to the resource bitmap matrix. In this embodiment, the GSM module sends a time-frequency domain resource occupation bitmap matrix of GSM carrier frequencies (that is, RB resource frequency domain position of LTE corresponding to carrier frequencies currently activated by GSM and occupation of 8 time slots of each activated carrier frequency by GSM, hereinafter referred to as resource bitmap matrix) to the time slot cooperative control unit, and optionally, the GSM module herein may be a GSM base station, or a GSM BSC controller; the resource bitmap matrix can be sent to the LTE module through the time slot cooperative control unit; the LTE module calculates whether LTE RB resources occupied by GSM carrier frequency can be scheduled on current and subsequent scheduling subframes of LTE according to the resource bitmap matrix and feeds back a confirmation message for starting cooperative scheduling to the time slot cooperative control unit, the time slot cooperative unit sends an LTE starting cooperative scheduling execution confirmation message to the GSM module after receiving the message, and the GSM module starts scheduling according to the resource bitmap matrix after receiving the confirmation message. Fig. 2 shows a cooperative flow chart of transmission and scheduling of bitmap matrix based on GSM time-frequency domain resource occupation between the GSM module and the LTE module.
In an optional embodiment, when the resource bitmap matrix of the GSM carrier frequency changes, the timeslot cooperative control unit sends an updated resource bitmap matrix to the LTE, and the LTE performs scheduling calculation according to the new resource bitmap matrix, in this embodiment, after determining, based on the timeslot cooperative frame synchronization signal, a target resource allowed to be used by the LTE module in the resource bitmap matrix, the method further includes: acquiring an updated resource bitmap matrix of the GSM module; and determining updated target resources available for the LTE module to use in the updated resource bitmap matrix based on the timeslot cooperative frame synchronization signal. Optionally, determining, based on the timeslot cooperative frame synchronization signal, an updated target resource available for the LTE module to use in the updated resource bitmap matrix includes: after confirming that the GSM module carries out resource scheduling according to the updated resource bitmap matrix, determining updated target resources which can be used by the LTE module in the updated resource bitmap matrix based on the time slot cooperative frame synchronization signal. In this embodiment, the time slot coordination control unit may update the resource bitmap matrix to the LTE module, where when the bitmap matrix of the GSM carrier frequency needs to be changed, the GSM module may send a new bitmap matrix to the time slot coordination control unit in advance by a certain time, the time slot coordination control unit sends the updated bitmap matrix to the LTE module, the LTE module receives the new bitmap matrix, and calculates whether LTE RB resources occupied by the GSM carrier frequency can be scheduled on each scheduling subframe according to a collection of two bitmap matrices before and after updating, and feeds back a confirmation message of having received the new bitmap matrix to the time slot coordination control unit by delaying a certain time, where the time advance and the delay may be several milliseconds or tens of milliseconds. After receiving the confirmation message of the LTE module, the time slot cooperative control unit sends the confirmation message to the GSM module, the GSM module can start scheduling the GSM user according to the new bitmap matrix, then the GSM module sends a notification message to the time slot cooperative control unit to feed back that the GSM module starts scheduling according to the new bitmap matrix, the time slot cooperative control unit sends a message that the old bitmap matrix fails to work to the LTE module, and the LTE module stops using the old bitmap matrix after receiving the notification message and only uses the new bitmap matrix. A flowchart for updating the GSM time-frequency domain resource occupation bitmap matrix between the GSM module and the LTE module may be shown in fig. 3.
In an optional embodiment, the determining, based on the timeslot coordinate frame synchronization signal, a target resource in the resource bitmap matrix that is allowed to be used by a long term evolution LTE module includes: based on an LTE time slot coordinated scheduling calculation counter TTI, a preset constant, a GSM time slot length and the time slot number contained in a GSM TDMA basic frame, determining a GSM time slot number Gslot1 occupied at the starting moment of the TTI and a GSM time slot number Gslot2 occupied at the ending moment of the TTI; when all time slots in the Gslot1 interval and the Gslot2 interval are determined not to be GSM activated time slot numbers corresponding to the RB position in a resource bitmap matrix, determining resources corresponding to the TTI time in the resource bitmap matrix as target resources allowed to be used by a Long Term Evolution (LTE) module; repeatedly performing the operation of determining whether the resource corresponding to each time in the resource bitmap matrix is a target resource allowed to be used by the Long Term Evolution (LTE) module with the counting step being a predetermined time (e.g., 1 ms). Optionally, the GSM timeslot number Gslot1 occupied by the TTI starting time may be determined by a first formula, and the GSM timeslot number Gslot2 occupied by the TTI ending time may be determined by a second formula, where the TTI is an LTE timeslot cooperative scheduling calculation counter, and the first formula is: gslot1 ═ rounding down (((TTI-OFFSET)/GSM slot length) modulo (the number of slots contained in the GSM TDMA basic frame)); the second formula is: gslot2 ═ rounding down (((TTI +1 ms-OFFSET)/GSM slot length) modulo (number of slots contained in GSM TDMA basic frame)); OFFSET is the predetermined constant as described above.
This embodiment is described below with reference to specific examples:
in this embodiment, taking as an example that only one GSM carrier frequency exists in a GSM carrier frequency resource bitmap matrix, and only a single time slot TS0 is activated in 0-8 TS time slots of a TDMA frame of the GSM carrier frequency, a schematic diagram is shown in fig. 4, where in fig. 4, a horizontal axis is a time domain, each unit is 1ms, a sequence number is represented by a TTI, which represents a scheduling time of LTE, and a basic period of LTE scheduling defined by a 3GPP protocol is 1 ms; the dot-filled columns represent TS0 (schedule slot 0) of GSM basic TDMA frames, each TS slot occupying a length of 577us and each TDMA frame comprising 8 slots as defined in the 3GPP protocol, so that the time interval of the same slot of two adjacent frames is 4.62ms (577us × 8); when only frequency domain co-scheduling is used, LTE cannot perform scheduling on three TTI time units (horizontal line filled columns) between two TSs 0 in fig. 4; when the timeslot cooperative scheduling is used, scheduling with LTE can be performed on three TTI time units (vertical line filled columns) between two TSs 0 in fig. 4, so that the scheduling efficiency of RB resources of LTE can be improved.
Because the minimum scheduling periods of GSM and LTE are not consistent, the 3GPP protocol specifies that one minimum scheduling slot of GSM is 577us, and the multiframe period of 13 frames is 60 ms. The protocol stipulates that the minimum scheduling period of the LTE is 1ms, in order to enable the LTE to automatically calculate schedulable resources at each moment according to the GSM time slot bitmap, the LTE adopts a time slot cooperative calculation period of 60ms or integral multiple of 60ms, and the LTE needs to restart calculation when the maximum value of the calculation period is reached. The LTE can calculate whether the LTE can schedule the RB resources in the resource bitmap matrix at the time of TTI through the following formula, the TTI is an LTE time slot cooperative scheduling calculation counter, counting can be started from the starting time of a GSM time slot cooperative frame synchronization period acquired by any LTE module, and the counting step is 1 ms. And the LTE calculates the GSM time slot position corresponding to the TTI moment through the following formula, compares the GSM time slot position with the GSM time slot occupation bitmap corresponding to each GSM carrier frequency in the GSM resource bitmap matrix, and if the GSM resource bitmap matrix is overlapped in time, the LTE can not schedule the RB resource corresponding to the GSM carrier frequency at the TTI moment, otherwise, the LTE can schedule the RB resource.
The calculation formula of the LTE schedulable TTI moment is as follows:
ggate 1 is rounded down (((TTI-OFFSET)/GSM time slot length) modulo (number of time slots contained in GSM TDMA basic frame))
Gslope 2 is rounded down (((TTI +1 ms-OFFSET)/GSM slot length) modulo (the number of slots contained in the GSM TDMA basic frame))
In the above formula, the OFFSET is the time OFFSET between the frame header of the LTE 10ms system frame and the GSM timeslot cooperative frame over the air interface, and is a fixed constant. Gslot1 and Gslot2 represent GSM time slot numbers occupied by LTE TTI scheduling time, Gslot1 is the GSM time slot number occupied by the LTE at the starting time of the TTI, Gslot2 is the GSM time slot number occupied by the LTE at the ending time of the TTI, and the occupation refers to that the occupation is represented if the TTI time and the GSM activation time slot are overlapped, whether the LTE can be scheduled at the TTI time can be judged according to the calculation results of Gslot1 and Gslot2, and the LTE can schedule RB resources corresponding to GSM carrier frequencies at the TTI time only when all time slots in the interval from Gslot1 to Gslot2 are not GSM activation time slots.
For example, when the TTI is 12, assuming that the OFFSET is 1ms, Gslot1 is 3 and Gslot2 is 4 are calculated according to the above formula, which indicates that LTE subframe 12 occupies GSM slots 3 and 4, occupies two consecutive GSM slots, and does not occupy slot 0, so LTE can schedule RB resources corresponding to a GSM carrier frequency in this subframe.
The above formula needs to ensure that the OFFSET is constant in the calculation process, and a fixed OFFSET can be ensured by the clock phase synchronization unit of the LTE and GSM modules.
In an optional embodiment, the method further comprises periodically resetting the TTI to 0. In this embodiment, after the LTE TTI counter starts counting, if the clock phase synchronization unit of the LTE and GSM modules accidentally malfunctions to cause a sudden GSM phase jump, which may cause a deviation between the LTE scheduling calculation result and the actual GSM timeslot position, the TTI counter needs to be periodically reset to 0, the counter period, i.e., the LTE timeslot cooperative calculation period, may be 60ms or an integer multiple greater than 60ms, and the time for resetting the TTI counter may be any time that the LTE reads the start time of the GSM timeslot cooperative frame synchronization period signal in embodiment 1. And after the TTI counter is reset, the LTE calculates the schedulable resource again according to the formula.
In an optional embodiment, since the length of one time slot of GSM is 577us, one basic scheduling time unit of LTE is 1ms, and one GSM time slot may span two LTE basic scheduling units, if the occupied positions of 8 non-empty time slots in one TDMA frame of GSM are irregular, for example, time slots are randomly allocated, which may cause more time fragments with a length of less than 1ms between the non-empty time slots, and these time fragments LTE may not be scheduled, so that the time that can be scheduled by LTE in one TDMA frame of GSM is reduced, which may cause a reduction in LTE scheduling efficiency.
If the GSM controller can allocate time slots continuously from one end or both sides of the TDMA frame preferentially, the continuous time slots can be left out, reducing time fragmentation and improving the scheduling opportunity of LTE.
The LTE scheduling efficiency under different GSM slot allocation schemes is demonstrated in fig. 5 and 6.
In fig. 5, two GSM users are allocated and occupy time slots 0 and 1 consecutively starting from the low end of the TDMA frame; two TTIs (2ms) can be scheduled within 5ms of LTE, and the scheduling efficiency is 40%.
In fig. 6, two GSM users discontinuously occupy TDMA frame time slots 0 and 5, only one TTI (1ms) can be scheduled in LTE 5ms, and the scheduling efficiency is 20%.
The time slot scheduling optimization method can be used for reducing time fragments of less than 1ms by the continuous allocation of the GSM from one end or two sides of a TDMA frame preferentially, so that the LTE can schedule on more GSM idle time slots.
Through the above description of the embodiments, those skilled in the art can clearly understand that the method according to the above embodiments can be implemented by software plus a necessary general hardware platform, and certainly can also be implemented by hardware, but the former is a better implementation mode in many cases. Based on such understanding, the technical solutions of the present invention may be embodied in the form of a software product, which is stored in a storage medium (e.g., ROM/RAM, magnetic disk, optical disk) and includes instructions for enabling a terminal device (e.g., a mobile phone, a computer, a server, or a network device) to execute the method according to the embodiments of the present invention.
