Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present application as detailed in the accompanying claims.
The following describes the technical solution of the present application in detail by taking a high-speed rail as an example, and it can be understood that the resource scheduling method, device and base station based on the high-speed mobile user provided in the present application are also applicable to other scenes of high-speed movement, which are not limited herein.
Under the resource scheduling policy of the current base station, the quality of network service provided by the high-speed rail network base station for users is low due to the following reasons:
(1) A large number of common users (users in the non-high-speed railway carriage) occupy the high-speed railway network base station cell, so that the load of the high-speed railway station cell is high, and the resources which can be allocated by the high-speed railway network base station to the users in the high-speed railway carriage are reduced;
(2) Because of the high-speed mobility and high shielding of the high-speed rail, the wireless environment of the users in the carriage is worse than that of the common users outside the carriage, the channel quality indication (channel quality indicator, CQI) value is relatively low, and the related resources allocated to the users in the carriage by the high-speed rail network base station are fewer;
(3) When a train passes through a high-speed railway network base station cell, according to the current coverage condition, the base station cell is used for about 8 seconds on average, so that the requirement on timeliness of data forwarding of the high-speed railway network base station is higher;
(4) When a train passes through a base station cell, assuming that 2400 people are about each train passenger, for a certain telecom operator, according to the user permeability of 10%, 240 users simultaneously access a high-speed railway network base station cell at the same time, so that strong data burst exists.
All the four factors can cause that the network service quality provided by the high-speed railway network base station for the user is not high, so that the use perception of the mobile user in the high-speed railway carriage is poor and is far lower than that of the large-network user outside the carriage, and therefore, policy adjustment is needed to be carried out so as to further improve the use perception of the mobile user in the high-speed railway carriage.
The main idea of the technical scheme of the application is as follows: based on the third generation partnership project (3rd Generation Partnership Project,3GPP) mobile network service quality protocol standard and a base station air interface resource scheduling principle, aiming at the high-speed mobile users identified based on Time Advance (TA) value change, the allocation and reservation priority (allocation and retention priority, ARP) and service quality classification identification (QoS class identifier, QCI) parameters of the users are set on the base station, and a 'care' resource scheduling strategy is configured for the users, so that the users can be allocated to more resources during access and service use, and the use perception of the mobile users in the railway carriage is improved.
First, the related terms referred to in the embodiments of the present application are explained as follows:
high speed mobile user: the mobile network user moving at a high speed relative to the base station is determined to be a high-speed mobile user if the moving speed of a certain user relative to the base station exceeds 150km/h, for example, by taking the speed of 150km/h as a judgment standard.
The average user: the speed-adjustable mobile users are defined by the same speed-adjustable mobile users, for example, the walking speed of an ordinary person is 5km/h, the riding speed of an ordinary person is 20km/h, and the speeds are all far lower than 150km/h, so that the corresponding mobile network users are ordinary users.
The resource scheduling method based on the high-speed mobile user is mainly applied to the base stations along the railway and the high-speed railway, wherein the base stations can be 2G base stations and 3G base stations, can also be 4G base stations or 5G base stations, and are not limited. It should be noted that, the base station in the embodiment of the present application has a function of setting QoS parameters, especially ARP and QCI parameters.
Fig. 1 is a flow chart of a first embodiment of a resource scheduling method based on a high-speed mobile user according to an embodiment of the present application, and as shown in fig. 1, the method in this embodiment includes:
s101, acquiring the variation of the TA value of the accessed user terminal.
In this step, in order to distinguish a high-speed mobile user from a large number of access users, the variation of the TA value is acquired for each access user terminal.
In the uplink transmission process of the user terminal, the TA value refers to that in order to enable the uplink data packet of the user terminal to reach the base station at a desired time, the radio frequency transmission delay caused by the distance is estimated, and the data packet is sent out in advance at a corresponding time. From the user terminal side, the TA value is essentially a negative offset between the start time of the received downlink subframe and the time of the transmitted uplink subframe. The base station can control the time of the uplink signals from different user terminals reaching the base station by properly controlling the offset of each user terminal in the same cell, thereby ensuring the orthogonal multiple access of different user terminals in the same cell on time frequency.
In one possible implementation manner, TA values of two adjacent uplink transmission signals sent by the same ue are obtained respectively, and the variation of the TA value of the ue is obtained by making a difference.
In this implementation manner, the base station determines the TA value of each ue by measuring the uplink transmission signals of the ue, so as to obtain the variation of the TA values of two adjacent uplink transmission signals.
The uplink transmission signal for TA value may be any signal, such as a channel sounding reference signal (sounding reference signal, SRS), a demodulation reference signal (demodulation reference signal, DMRS), etc.
In the embodiment of the application, the user terminal can be a mobile phone, a tablet personal computer, a notebook computer and the like
In this step, when there are a plurality of user terminals accessing the base station at the same time, the base station may acquire the variation of TA values of the plurality of accessed user terminals, respectively. In addition, the variation of the TA value may not be limited to two adjacent uplink transmission signals, or may be a variation of the TA value within a preset duration, or a variation of the TA value of a plurality of adjacent uplink transmission signals, which is not limited herein.
S102, determining whether the user using the user terminal is a high-speed mobile user or not according to the variation of the TA value.
In this step, after S101, the moving speed of the ue is determined according to the obtained variation of the TA value of the ue, so as to determine whether the user currently using the ue is a high-speed moving user.
The TA value represents the distance between the user terminal and the antenna port of the base station, so that the base station can analyze the change of the distance between the user terminal and the base station by continuously acquiring the TA value of the user terminal, and the moving speed of the user terminal on the high-speed rail can be rapidly analyzed.
And S103, if the user is determined to be a high-speed mobile user, setting the allocation and maintenance priority of the user terminal as the highest priority of the ARP parameter.
In this step, if it is determined that the user is a high-speed mobile user, the priority level of the ARP parameter of the corresponding user terminal is set to the highest level. It will be appreciated that if the priority of the ARP parameter of the user terminal is already the highest, the ARP parameter of the user terminal is kept unchanged.
ARP is one of the key parameters of QoS, and specifically includes priority, preemption capability and preempted capability, mainly used for access control, and ARP priority is used to mark the importance of a bearer resource request, and can be used to decide whether a request for bearer establishment or bearer modification is accepted or rejected, and also to decide which bearer can be released (preempted) when the system is resource limited. The higher the ARP priority, this means that the corresponding user terminal will preferentially enjoy the service for access.
The setting ranges of the ARP of different device manufacturers are different, for example, if the setting range of the ARP of a certain device manufacturer is 0-7, where the priority represented by "7" is the highest, the priority of the ARP parameter of the user terminal of the identified high-speed mobile user is set to "7" in this step.
S104, controlling the resource scheduling of the user terminal based on the ARP parameter.
In this step, the resource scheduling of the user terminal of the high-speed mobile user is controlled based on the ARP parameter set in S103, and because the ARP parameter of the high-speed mobile user has the highest priority, the base station may prioritize the user terminal of the high-speed mobile user when performing resource scheduling, thereby improving the access success rate of the user terminal of the high-speed mobile user, and further having an opportunity to perform resource allocation for the user terminal of the high-speed mobile user.
It should be noted that, if the user is determined to be a normal user in S102, that is, a non-high-speed mobile user, the base station does not make any modification to the ARP parameter of the user, that is, performs resource scheduling for the user terminal of the normal user according to the ARP parameter in the user subscription information.
In one possible implementation, performing resource scheduling for the user terminal based on the ARP parameter includes:
and performing admission control and congestion control on the user terminal based on the ARP parameter.
In the implementation manner, because the ARP parameter of the high-speed mobile user has the highest priority, in the admission control, the user terminal of the high-speed mobile user can be accessed to enjoy network service preferentially, and in the congestion control, the base station can perform forced disassembly processing on the user with lower priority, so that the access success rate of the user terminal of the high-speed mobile user is improved, the user terminal of the high-speed mobile user is ensured to be accessed and preempted to resources more easily than the user terminal of the common user, and the service quality of the high-speed mobile user is improved.
Optionally, the admission control includes user number based admission control and QoS satisfaction rate based admission control.
In this embodiment, by acquiring the variation of the TA value in advance of the time of the accessed user terminal, it is determined whether the user using the user terminal is a high-speed mobile user according to the variation of the TA value, if it is determined that the user is a high-speed mobile user, the priority of the ARP parameter of the allocation and retention priority of the user terminal is set to be the highest, and resource scheduling is performed for the user terminal based on the ARP parameter, so as to provide differentiated services for the high-speed mobile user.
Fig. 2 is a flow chart of a second embodiment of a resource scheduling method based on a high-speed mobile user according to the embodiment of the present application, and as shown in fig. 2, the method of the present embodiment includes:
s201, acquiring the variation of the TA value of the accessed user terminal.
In this step, the variation of the time advance TA value of the accessed ue is obtained, and the specific implementation manner is similar to that in the first embodiment, and will not be described here again.
S202, determining the moving speed of the user terminal according to the variation of the TA value.
In this step, since the TA value represents the distance between the ue and the base station antenna port, the change of the distance between the ue and the base station antenna port can be determined by the change of the TA value, so as to determine the displacement change of the ue, and then the moving speed of the corresponding ue can be determined by acquiring the time interval between the two TA values when determining the change of the TA value.
In one possible implementation manner, if the variation of the TA value is the variation of the TA value according to the two adjacent uplink transmission signals, the moving speed of the user terminal can be determined according to the time interval and the variation of the displacement by acquiring the time interval for transmitting or receiving the two uplink transmission signals and calculating the variation of the displacement of the user terminal corresponding to the variation of the TA value.
And S203, if the moving speed is greater than the preset speed, determining that the user using the user terminal is a high-speed moving user.
In this step, the moving speed of the ue determined in S202 may be compared with a preset speed, and if the moving speed of the ue is greater than the preset speed, it is determined that the user using the ue is a high-speed moving user.
The preset speed can be set according to actual conditions, and is mainly used for distinguishing the high-speed mobile user from the common user, so that the preset speed is set to ensure that the high-speed mobile user and the common user can be distinguished.
In this step, if the moving speed is less than or equal to the preset speed, determining a common user of the user corresponding to the user terminal.
Accordingly, the base station has a function of setting and storing a preset speed therein.
S204, if the user is determined to be a high-speed mobile user, setting the allocation and maintenance priority ARP parameter priority of the user terminal to be the highest, and setting a special service quality classification identifier QCI for the user terminal, wherein the priority of the special QCI is higher than that of the QCI of the common user terminal.
In this step, if it is determined that the user is a high-speed mobile user through S202-203, the priority of the ARP parameter of the corresponding user terminal is set to the highest level, and meanwhile, a dedicated QCI is set for the user terminal, and the set priority of the dedicated QCI is guaranteed to be higher than the QCI priority of the common user terminal. The implementation manner of setting the ARP parameter of the user terminal to the highest priority is similar to that in the first embodiment, and will not be described herein.
QCI is a value that includes indicia of priority, packet delay, and acceptable packet error rate, nine different QCI values are defined in the 3GPP standard, as shown in table 1, each QCI being associated with a priority, priority 1 being the highest priority. The value of the bearer QCI determines the relevant processing strategy of the base station. For example, in the resource scheduling process, the QCI may be used as a priority indication for carrying the data packet, so that the data packet with high QCI priority is scheduled preferentially, thereby providing a higher internet surfing rate for the user with high QCI priority.
Like ARP, QCI can also be applied to both guaranteed bit rate (guaranteed bit rate, GBR) and Non-guaranteed bit rate (Non-guaranteed bit rate, non-GBR) bearers.
TABLE 1
QCI Type(s) Priority level Delay (ms) Packet error rate Business sample
1 GBR 2 100 10 -2 Conversational speech
2 GBR 4 150 10 -3 Conversational video
3 GBR 3 50 10 -3 Real-time game
4 GBR 5 300 10 -6 Non-conversational speech

8 Non-GBR 8 300 10 -6 TCP-based video services
9 Non-GBR 9 300 10 -6 TCP-based video services
For example, if the default bearer of the normal user is 6, any one of QCI 1-5 may be selected as the dedicated QCI of the high-speed mobile user, so as to ensure that the priority of the high-speed mobile user is higher than the priority of the normal user in the service use process, thereby providing a faster internet surfing speed and a higher level of service quality for the high-speed mobile user.
S205, controlling the resource scheduling of the user terminal based on the ARP parameter and the special QCI.
In this step, after S204, the base station controls resource scheduling of the user terminal of the high-speed mobile user based on ARP and QCI parameters set for the high-speed mobile user, so as to ensure that the high-speed mobile user has better internet surfing experience.
In one possible implementation, performing resource scheduling for a user terminal based on ARP parameters and a dedicated QCI includes:
and carrying out admission control and congestion control on the user terminal based on the ARP parameter, and controlling the forwarding of the bearing data packet and the air interface scheduling of the user terminal based on the special QCI.
The specific implementation manner of performing admission control and congestion control on the user terminal based on the ARP parameter is similar to that in the first embodiment, and will not be described herein.
The method for controlling the forwarding of the bearing data packet and the air interface scheduling of the user terminal based on the special QCI specifically comprises the following steps:
(1) In the whole bearing layer, the high-speed mobile user sets higher priority in terms of dispatch weight, access threshold, queue management threshold, link layer protocol configuration and the like.
(2) At the air interface scheduling level, the channel quality indication (channel quality indication, CQI) value (increasing CQI bias), the modulation allocation proportion of quadrature amplitude modulation (quadrature amplitudemodulation, QAM), the proportion of large data packets in resource block allocation, the allocation proportion of high-efficiency coding, the allocation of more physical resource blocks (physical resource block, PRB) and the like are improved for high-speed mobile users.
In the step, the transmission of the bearing data packet and the air interface scheduling of the user terminal of the high-speed mobile user are controlled based on the special QCI, so that the high-speed mobile user has shorter service time delay and higher service rate, and the user can be ensured to be distributed to more resources in the service using process.
In this embodiment, the mobile speed of the user terminal is determined by acquiring the variation of the TA value in advance of the time of the accessed user terminal, if the mobile speed is greater than the preset speed, the user using the user terminal is determined to be the high-speed mobile user, if the user is determined to be the high-speed mobile user, the priority of the ARP parameter of the allocation and retention priority of the user terminal is set to be the highest, the dedicated service quality classification identifier QCI is set for the user terminal, the priority of the dedicated QCI is higher than the priority of the QCI of the common user terminal, and the resource scheduling is performed for the user terminal based on the ARP parameter and the dedicated QCI, so that differentiated services are provided for the high-speed mobile user.
