Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for adaptive data offloading.
Background
Different from an independent architecture of LTE, in order to implement rapid deployment of 5G, an NSA (non-standby) Option3X is currently adopted to meet the requirement of an Enhanced Mobile Broadband (eMBB) scene at an initial stage.
NSA offloading requires a terminal to have corresponding capabilities, such as merging of Packet Data Convergence Protocol (PDCP) for downlink offloading and splitting of uplink offloading.
3GPP (3rd Generation Partnership Project) also has a corresponding definition for the flow implementation. For uplink offloading, the base station sends a Primary Path and a Buffer Threshold parameter to the terminal through an RRC (Radio Resource Control) reconfiguration message, where the Primary Path is LTE (Long Term Evolution)/NR (New Radio interface), and when an uplink Buffer is greater than the Buffer Threshold, offloading is started to a Secondary Path. The terminal reports and caches through LTE BSR (Buffer Status Report)/NR BSR; in the prior art, the Primary Path is mostly set to NR, and the rate advantage of NR is preferentially utilized.
For downlink shunting, LTE RLC ((Radio Link Control)/NR RLC) reports DDDS (downlink Data Delivery status) to NR PDCP actively/passively through Xn interface/F1 interface, respectively, to describe the processing capability of the current Path, DDDS content includes information such as expected throughput, maximum SN number that RLC has sent to MAC, average queuing delay of RLC PDU, and the like, and NR PDCP determines the capability of the master and slave nodes according to DDDS reported by LTE RLC/NR RLC, thereby performing proportional shunting.
The sending end needs to make the allocation of two packet sequence numbers under the condition of shunting, so as to ensure that the packet delay difference of adjacent sequence numbers is shortest when the sending end reaches a receiving end, the receiving end needs to use a proper reordering timer, and the longer the timer is, the better the disorder condition can be coped with, the smaller packet loss rate is ensured, but the waiting delay of the data packet in a receiving buffer area can be lengthened; otherwise, packet loss is high, and time delay is short. Both high packet loss and high delay cause the TCP sending window to grow slowly, and the maximum window to decrease, thus causing the rate to decrease. Parameters such as the reordering timer and the flow control threshold will affect the shunting performance and bring some complexity.
In addition, since the network bandwidth provided by the NR device is 100M, the LTE device is only 20M, and even only 5M exists in a part of regions, opening offloading will have a certain impact on the LTE current network users. In the prior art, an adaptive shunting algorithm is designed according to an index strongly related to shunting performance, and the algorithm has the condition of unobvious shunting gain for good points in downlink, and also brings extra complexity and generates interference on the existing network.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. 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 invention.
In order to overcome the problems in the prior art, the invention of the embodiment of the invention is conceived to judge whether to start shunting at the current moment by comparing the magnitude relation between the shunting opening rate and the opening rate threshold value of two time periods and combining one or more of the increasing and decreasing trends of the shunting gain of the two time periods, the shunting gain of the first time period and the coverage condition of the first time period NR, so that the method is flexibly applicable to various scenes, can effectively bring the shunting gain in the scene needing shunting, and reduces the complexity and the influence on the users of the LTE existing network in the scene needing shunting.
Fig. 1 is a schematic flow chart of an adaptive data offloading method according to an embodiment of the present invention, as shown in fig. 1, including:
s101, according to feedback information of a terminal, obtaining shunting gain and shunting opening rate respectively corresponding to two continuous time periods with the same length before the current time and coverage information of NR corresponding to a first time period; wherein the two periods include the first period and a second period, and the first period is adjacent to the current time.
The 3GPP also has corresponding definitions for the flow distribution implementation scheme, where for uplink flow distribution, the base station issues a Primary Path and a Buffer Threshold parameter to the terminal through an RRC reconfiguration message, where the Primary Path is LTE/NR, and when the uplink Buffer is greater than the Buffer Threshold, flow distribution is started to the Secondary Path. The terminal reports and caches the LTE BSR/NR BSR; most of the current Primary Path cases are set as NR, and the rate advantage of NR is preferentially utilized;
for downlink shunting, the LTE RLC/NR RLC actively/passively reports DDDS (Downlink Data Delivery status) to the NR PDCP through an Xn interface/F1 interface respectively for describing the processing capacity of the current Path, the DDDS content comprises information such as expected throughput, the maximum SN number sent by the RLC to the MAC, the average queuing delay of the RLC PDU and the like, and the NR PDCP judges the capacity of the main node and the auxiliary node according to the DDDS reported by the LTE RLC/NR RLC so as to perform proportional shunting;
the LTE BSR/NR BSR reporting policy and how the NR PDCP shunts according to the DDDS reported from the Xn/F1 interface belong to proprietary algorithms of manufacturers, and currently, some manufacturers implement a downlink adaptive shunting scheme based on delay estimation, where delay is Buffer transmitted in the process of two consecutive DDDS/interval time of two consecutive DDDS, and when the value is smaller than a certain threshold of a cell, it indicates that the processing capability is good enough, data transmission can be performed in this Path.
Therefore, the prior art does not propose a scheme for performing data offloading based on coverage, but the embodiment of the present invention not only takes the coverage situation as the transition point corresponding to adaptive offloading, but also shows a trend in general at different times, although the situations such as the current network load or coverage of the terminal location may show different characteristics, such a trend may bring about changes in offloading gain and SS-RSRP, and may also affect the offloading performance of the terminal at the next time, so the embodiment of the present invention innovatively introduces offloading gain and offloading turn-on rate respectively corresponding to the first two periods of the current time into the offloading judgment process.
Specifically, the average rates of LTE and NR, the splitting parameters, and the SS-RSRP parameter (synchronous Reference Signal Receiving Power) in the first two periods of the current time are obtained according to the feedback information of the terminal, where the average rates of LTE and NR may be obtained by averaging the rates acquired at each acquisition time in a period, and the splitting state represents a state of whether splitting is opened or closed at the acquisition time. The time lengths in different time periods of the embodiment of the invention are equal, the number of the acquisition time in each time period is at least 1, and the number of the acquisition time in different time periods can be the same or different.
And obtaining the shunting gain of the second time period according to the average rate of the LTE and the NR of the second time period.
Obtaining the shunting gain of the first time interval according to the average rate of LTE and NR of the first time interval;
specifically, T is defined as the duration of a time period, and two time periods before the current time are respectively a (T-2) time period and a (T-1) time period, wherein the (T-1) time period is closer to the current time. For example, if the current time is 10 am and T is 1 hour, the time interval (T-1) is 9 to 10 o' clock; the (T-2) period is from 8 to 9. Defining the average rate of LTE as LTERateAverage rate of NR ofRateThe shunt gain for the (T-1) period and the (T-2) period is calculated according to the following formula:
wherein, SplitGainT-1Shows the split gain, SplitGain, of the (T-1) periodT-2Representing the shunt gain for the (T-2) period,
denotes the average rate of LTE for the (T-1) period,
denotes the average rate of LTE for the (T-2) period,
denotes the average rate of NR for the (T-1) period,
represents the average rate of NR over the (T-2) period.
For any one of the two time periods, acquiring the shunting opening rate of the time period according to the quotient of the number of the acquisition moments of shunting opening in the time period and the total number of the acquisition moments in the time period;
for example, if there are 5 acquisition instants in the first period, where only 2 acquisition instants are shunted on, the shunt on rate for the first period is 2/5, i.e. 40%.
And the SS-RSRP parameter of the NR is used for characterizing the coverage condition of the NR.
And S102, judging whether to start shunting at the current moment according to the magnitude relation between the shunting opening rate and the opening rate threshold value respectively corresponding to the two time periods and by combining one or more of the increasing and decreasing trends of the shunting gain of the two time periods, the shunting gain of the first time period and the coverage condition of the NR of the first time period.
According to the embodiment of the invention, the size relation between the shunt opening rate and the opening rate threshold value respectively corresponding to two time periods is used as an initial pre-judgment stage, and the shunt opening or the shunt closing is absolute, namely, the statistical difference does not exist along with the performance difference of terminal brands, so that the state of the terminal can be judged more accurately based on the comparison between the shunt opening rate and the opening rate threshold value. If the shunting opening rates of the two time periods are both larger than the opening rate threshold value, the shunting gain caused by shunting opening in the two time periods is objective, so that shunting can be continuously opened at the current moment by preliminary judgment; if the shunting opening rates of the two time periods are both smaller than the opening rate threshold value, the shunting gain difference caused by shunting opening in the two time periods is strong, so that shunting is closed at the current moment by preliminary judgment; if the shunting opening rate of the second time interval is greater than the opening rate threshold value, and the shunting opening rate of the first time interval is less than the opening rate threshold value, the shunting gain is necessarily reduced, and the shunting is closed by preliminary judgment, and if the shunting opening rate of the second time interval is less than the opening rate threshold value, and the shunting opening rate of the first time interval is greater than the opening rate threshold value, the shunting gain is necessarily increased, and the shunting is preliminarily judged to be opened.
By preliminarily judging whether to start shunting, the method can also judge for many times based on one or more of increasing and decreasing trends of shunting gains of the two time periods, the shunting gain of the first time period and the coverage condition of the NR of the first time period, so as to finally determine whether to start shunting, the relation between expenditure and income can be repeatedly considered by the whole set of logic, and the shunting gain is improved to the greatest extent.
And S103, opening or closing the shunt according to the judgment result.
It should be understood that, in the embodiments of the present invention, in consideration of the rate advantage of NR, the primary path is set as NR, and the secondary path is set as LTE, that is, when the offloading is turned on, LTE and NR are in communication connection with the terminal, and when the offloading is turned off, only NR is in communication connection with the terminal.
The self-adaptive data distribution method of the embodiment of the invention judges whether distribution is started at the current moment or not by comparing the size relation between the distribution opening rate and the opening rate threshold value of two time periods and combining one or more of the increasing and decreasing trends of the distribution gain of the two time periods, the distribution gain of the first time period and the coverage condition of the NR of the first time period, is flexibly suitable for various scenes, can effectively bring the distribution gain in the scene needing distribution, reduces the complexity in the scene needing distribution and reduces the influence on the LTE current network users.
On the basis of the foregoing embodiments, as an optional embodiment, the determining whether to start shunting at the current time according to a magnitude relationship between shunting opening rates and opening rate thresholds respectively corresponding to the two time periods and in combination with one or more of increasing and decreasing trends of shunting gains of the two time periods, shunting gain of the first time period, and a coverage condition of NR includes:
if the shunting opening rates of the two time periods are both greater than the opening rate threshold value, determining the increasing and decreasing trends of the shunting gain of the two time periods;
as can be seen from the above description, if the shunt opening rates in the two periods are both greater than the opening rate threshold, it may be preliminarily determined that the current time is suitable for opening the shunt, and at this time, further combining with the increasing and decreasing trend of the shunt gain, it may be determined at a high rate whether the terminal is moving to the weak coverage area or the strong coverage area, if the shunt gain is decreasing (decreasing), it indicates that the terminal is moving to the strong coverage area, and it indicates that the terminal is moving to the weak coverage area in a reverse regular manner.
If the shunting gain of the two time periods is decreased progressively, judging whether the shunting gain of the first time period is greater than a gain threshold value;
it should be noted that, if the shunt gain is decreasing, it indicates that the terminal is moving to the strong coverage area, at this time, it is continuously determined whether the shunt gain in the first time period is greater than the gain threshold value, so as to determine whether the shunt gain in the time period closest to the current time is in accordance with the expectation, and if the shunt gain is less than the gain threshold value, it indicates that the shunt gain is not in accordance with the expectation, and the shunt should be closed at the current time.
If the shunting gain in the first time period is smaller than a preset gain threshold value, the shunting is closed;
if the shunting gain in the first time interval is greater than the gain threshold, judging whether the coverage condition of the NR in the first time interval is less than the coverage threshold;
if the shunt gain in the time interval closest to the current time is greater than the gain threshold, it is indicated that although the shunt gain is decreased, the first time interval gain is still considerable, and whether the coverage condition of the first time interval NR is smaller than the coverage threshold is further determined, it is possible to know whether the first time interval is in a weak coverage area, and if the coverage condition is smaller than the coverage threshold, it is indicated that the terminal is in the weak coverage area, and at this time, opening the shunt brings more shunt gain, so it is determined to open the shunt, and otherwise, it is possible to know that the terminal is in a strong coverage area, and it is not necessary to perform shunt, so it is determined to close the shunt, and therefore:
if the coverage condition of the first period NR is smaller than the coverage threshold, the shunting is started, and if the coverage condition of the first period NR is larger than the coverage threshold, the shunting is closed.
It should be noted that, if the shunt gain in the two time periods decreases, it indicates that the shunt gain in the second time period is greater than the shunt gain in the first time period, that is, the shunt gain of the terminal decreases in the two time periods (such a change in the shunt gain may be caused by a change in the current network load, may be caused by a change in coverage, and so on, which represents a trend of a change in the terminal), and if the shunt gain in the previous time period is smaller than the preset gain threshold, the shunt is turned off. If the shunting gain of the first time interval is still larger than the preset gain threshold, the coverage condition of the first time interval is judged at the same time, when the current time interval is in a weak coverage scene (for example, SS-RSRP < -88dBm, the value can be adjusted according to a planning index), shunting is started, and otherwise, shunting is closed.
On the basis of the foregoing embodiments, as an optional embodiment, if the shunt opening rates in the two time periods are both greater than the opening rate threshold, determining an increasing and decreasing trend of the shunt gain in the two time periods, and then further including:
if the shunting gain of the two time periods is increased progressively, judging whether the shunting gain of the first time period is greater than a gain threshold value;
it should be noted that, if the shunt gain of the two time periods is increased incrementally, it is indicated that the shunt gain is being increased, but this does not necessarily mean that the shunt gain is expected, so it is determined whether the shunt gain of the first time period is greater than the gain threshold, if so, it is indicated that the shunt is reasonable, the shunt should be turned on at the current time, if less than the gain threshold, it is indicated that the shunt gain is increased but has not yet reached the expectation, and further, it is determined that the terminal is in a weak coverage area or a strong coverage area according to the coverage condition of the NR of the first time period, if the coverage condition of the NR of the first time period is less than the coverage threshold, it is indicated that the terminal is in the weak coverage area, the shunt should be turned on, if the coverage condition of the NR of the first time period is greater than the coverage threshold, it is indicated that the terminal is in the strong coverage area, the shunt should be turned off, therefore:
if the shunting gain in the first time period is larger than the gain threshold value, shunting is started;
if the shunting gain in the first time interval is smaller than the gain threshold, judging whether the coverage condition of the NR in the first time interval is smaller than the coverage threshold;
if the coverage condition of the first period NR is smaller than a coverage threshold value, shunting is started; and if the coverage condition of the first period NR is larger than the coverage threshold, closing the shunting.
On the basis of the foregoing embodiments, as an optional embodiment, the determining, according to a magnitude relationship between the shunt opening rate and the opening rate threshold corresponding to each of the two time periods, and in combination with one or more of an increasing and decreasing trend of the shunt gain in the two time periods, the shunt gain in the first time period, and a coverage situation of the first time period NR, whether to shunt at the current time includes:
if the shunting opening rates of the two time periods are both smaller than the opening rate threshold value, judging whether the coverage condition of the NR in the first time period is smaller than the coverage threshold value;
if the reposition of redundant personnel opening rate of two periods all is less than the opening rate threshold value, it is less to open the gain that the reposition of redundant personnel brought at two moments before preliminary judgement, further judges the coverage condition this moment, if the terminal is in weak coverage area, then opens the reposition of redundant personnel, if be in strong coverage area, then closes the reposition of redundant personnel, consequently:
if the coverage condition of the first period NR is smaller than the coverage threshold, the shunting is started, and if the coverage condition of the first period NR is larger than the coverage threshold, the shunting is closed.
On the basis of the foregoing embodiments, as an optional embodiment, the determining, according to a magnitude relationship between the shunt opening rate and the opening rate threshold corresponding to each of the two time periods, and in combination with one or more of an increasing and decreasing trend of the shunt gain in the two time periods, the shunt gain in the first time period, and a coverage situation of the first time period NR, whether to shunt at the current time includes:
if the shunting opening rate in the second time period is greater than the opening rate threshold value and the shunting opening rate in the first time period is less than the opening rate threshold value, judging whether the coverage condition of the first time period NR is less than the coverage threshold value;
if the diversion opening rate in the second time period is greater than the opening rate threshold and the diversion opening rate in the first time period is less than the opening rate threshold, it is indicated that the terminal may gradually move from the weak coverage area to the strong coverage area, and at this time, the coverage condition of the first time period NR is determined, that is, whether diversion is closed or not can be determined according to whether the terminal is already in the strong coverage area in the first time period, so that:
if the coverage condition of the first period NR is smaller than the coverage threshold, the shunting is started, and if the coverage condition of the first period NR is larger than the coverage threshold, the shunting is closed.
On the basis of the foregoing embodiments, as an optional embodiment, the determining, according to a magnitude relationship between the shunt opening rate and the opening rate threshold corresponding to each of the two time periods, and in combination with one or more of an increasing and decreasing trend of the shunt gain in the two time periods, the shunt gain in the first time period, and a coverage situation of the first time period NR, whether to shunt at the current time includes:
if the shunting opening rate of the second time period is smaller than the opening rate threshold value and the shunting opening rate of the first time period is larger than the opening rate threshold value, judging whether the shunting gain of the first time period is larger than a preset gain threshold value;
if the shunt opening rate of the second time period is smaller than the opening rate threshold and the shunt opening rate of the first time period is larger than the opening rate threshold, it indicates that the terminal may move to the weak coverage area, at this time, the shunt gain of the first time period NR is distinguished, if the shunt gain of the first time period NR is already in expectation, then the shunt opening at the current time should also be in expectation, and if the shunt gain of the first time period NR is not yet in expectation, then we can choose to close the shunt at the current time first, so:
