Description
Technical Field
The present application relates to the field of computers, and in particular, to a method and an apparatus for allocating a link for a mobile terminal.
Background
Currently, multipath TCP (MPTCP) is more and more widely used, and when a terminal or a mobile terminal has a plurality of independent internet protocol addresses (IP addresses), MPTCP can establish an individual TCP connection for each IP address, and since each TCP connection can transmit data, the rate can be greatly increased. The MPTCP needs to allocate the load of each TCP connection, and the policy algorithm for allocation usually uses a minimum round trip delay data scheduling algorithm (RTT algorithm), that is, calculates the round trip delay of each TCP link in real time, where the link delay is small, which indicates that the link has good quality and high speed, and when the load is allocated next time, the load is allocated more.
The method has good effect in the application environment of a wired network (such as Intenet), but the effect is general when the wireless network is connected: when the mobile terminal uses a plurality of wireless links, the rate of the TCP queue is lower than that of a single link due to the blockage of the TCP queue head; because the link quality is not good, the MPTCP continuously retransmits data and is continuously reconnected, so that the rate is not obviously improved, but the energy consumption is greatly increased, the mobile terminal is difficult to load the energy consumption, and the use time is greatly shortened.
The RTT algorithm works well in an application environment of a wired network because the wired network is very stable. However, the wireless network is unstable, the first reason is that wireless signals are unstable, and the second reason is that a source (e.g. a mobile phone) may still move continuously, and the RTT with a small data amount in the previous period may be disconnected in the next second.

Fig. 1 shows a flowchart of a method for allocating a link for a mobile terminal according to an aspect of the present application, the method including: S100-S300, wherein in S100, a historical data table in which historical link connection data of links are stored is obtained from a cloud server, and target rate data of the corresponding links in the historical data table are screened out based on the current position and the current time of the mobile terminal and operator information of each link; in S200, calculating a historical speed parameter of each link according to the target speed data, determining the reliability of the historical speed parameter based on the target speed data, and determining a corresponding weight value according to the reliability; in S300, the current link rates of all links in the mobile terminal are obtained, the distribution load ratio of each link is calculated according to the current link rate of a single link, the corresponding historical rate parameter, the weight value and the minimum round trip delay data scheduling algorithm, and the distribution processing of all links is completed according to the distribution load ratio. Therefore, the loads of a plurality of links of the mobile terminal are reasonably distributed, the connection speed of the mobile terminal is effectively improved, the energy consumption of the mobile terminal in the speed increasing process is reduced, and the application stability in the wired network and wireless network environments is ensured.
Here, the routing path of the wireless internet access of the mobile terminal (such as a mobile phone) is as follows: the mobile phone is connected to the operator base station through a wireless signal, the operator base station is connected to the wireless core network, and the wireless core network is connected to the Internet. The signal quality from the operator base station to the Internet is in fact several orders of magnitude higher than that of the wireless network, so the bottleneck is in the section of "going to the operator base station via wireless signals". In this section, the wireless signal coverage of the operator, the signal strength, the signal reflection and shielding capabilities of surrounding buildings, and in general, the position of the mobile terminal, and the quality of the wireless signal are in one-to-one correspondence.
Specifically, in S100, a history data table storing historical connection data of links is obtained from the cloud server, and target rate data of a corresponding link in the history data table is screened out based on the current location of the mobile terminal, the current time, and operator information of each link. Here, the history data table may include history connection data such as a real-time location historically uploaded by the mobile terminal, a time for uploading the real-time location, and a connection rate of each link with the base station and operator information corresponding to the link. And screening out a corresponding link in the historical data table based on the current position and the current time of the new mobile terminal and the operator information of each link, and taking the connection rate data of the corresponding link to the base station as target rate data.
In S200, a historical rate parameter of each link is calculated according to the target rate data, reliability of the historical rate parameter is determined based on the target rate data, and a corresponding weight value is determined according to the reliability. Here, the link reliability of each link is determined based on the target rate data, for example, different levels of link reliability are determined according to the data amount corresponding to the data of the target rate, and a corresponding weight value is further determined based on the determined link reliability level, and the weight value can be used for determining the reliability of the target rate data, and the higher the reliability is, the greater the weight of the link load calculation using the target rate data is. When the link data is completely unreliable, for example, any link data is not matched in a historical data table, the load calculation is directly carried out on the link by using a minimum Round Trip Time (RTT) data scheduling algorithm. Each link can match a large amount of target speed data in the historical data table, for example, historical connection data of the same operator with a single link within 2.5 meters around the current GPS position of a new mobile terminal and within 5 minutes around the same time within 5 days are selected as the target speed data, and historical speed parameters, such as average speed and speed fluctuation rate, are calculated according to the connection speed in the target speed data.
In S300, the current link rates of all links in the mobile terminal are obtained, the distribution load ratio of each link is calculated according to the current link rate of a single link, the corresponding historical rate parameter, the weight value and the minimum round trip delay data scheduling algorithm, and the distribution processing of all links is completed according to the distribution load ratio. The current link rates of all links in the mobile terminal are obtained, the historical rate parameters include, but are not limited to, an average rate and a rate fluctuation rate, the distribution load ratio of the link can be calculated jointly according to the rate proportion of the current link rate of a single link in all links, a weight value, the average rate, the rate fluctuation rate and an RTT algorithm, and so on, the distribution load ratio of each link is obtained, the load of each link is distributed based on the distribution load ratio, so that the loads of multiple links of the mobile terminal are accurately distributed, the connection rate of the mobile terminal is effectively improved, the energy consumption of the mobile terminal in the process of increasing the rate is reduced, and the problem of instability of calculating the load ratio only by using the RTT algorithm in a wireless network environment is effectively avoided.
In an optional embodiment of the present application, in S400, when the multi-path TCP is started on the mobile terminal, the current location and the current time of the mobile terminal and the connection rate of each link of different operators are continuously sent to the cloud server, so as to establish a historical data table storing historical connection data of the links on the cloud server. When multipath TCP (MPTCP) is started on the mobile terminal, the current position and the current time of the mobile terminal and the connection rate of each link of different operators are continuously sent to a cloud server, and a historical data table storing historical connection data of the links is established on the cloud server so as to provide data reference for the subsequent link allocation of a new mobile terminal.
It should be noted that the step identification numbers are only used for identification processing of a single step, and do not represent the execution sequence of each step.
In an optional embodiment of the present application, in S100, information data corresponding to a current location of the mobile terminal is obtained, and current time and operator information of each link on the mobile terminal are determined; and matching target speed data of the corresponding operator link within a distance threshold and a time threshold in a historical data table based on the information data corresponding to the current position, the current time and the operator information of each link. Here, the information data corresponding to the current location of the mobile terminal may be acquired in a GPS or other manner, and the current time and the operator information of each link on the mobile terminal are determined. Since factors affecting the transmission rate of the radio include location and time: the location determines the signal coverage quality of the operator base station and the influence of surrounding buildings on the signal, while the time determines the distribution of people in a single location, and more people will cause the connection rate to be reduced. For example, the connection rate is definitely reduced when more people are on duty at 9 am; at 9 pm, when the same position is few, the speed is increased. Therefore, the input of the table is the GPS position information, the time and the speed of the operator, which are provided by the mobile terminal, and the data are transmitted to the server in the cloud end to become historical data.
In an optional embodiment of the present application, in S200, the reliability of the historical rate parameter is determined based on the data amount of the target rate data corresponding to the single link; a corresponding weight value is determined based on the reliability. Here, the data amount of the corresponding target rate data screened out according to the single link may be used to judge the level of reliability of the historical rate parameter, and the corresponding weight value may be determined based on the level of reliability. In an alternative embodiment of the present application, a reliability level threshold may be set to rank. For example, if the number of historical data within 2.5 meters around the GPS position of the new source machine and within 5 minutes around the same time within 5 days exceeds 10000, the historical data is regarded as reliable historical data, and the weight value of the target rate data is 80%; 3000-10000 historical data are obtained within 2.5 meters around the GPS position of the new source machine and within 5 minutes before and after the same time within 5 days, the historical data are regarded as secondary reliable historical data, and the weight value of the target speed data is 50%; if 1000-3000 historical data exist within 2.5 meters around the GPS position of the new source machine and within 5 minutes before and after the same time within 5 days, the historical data are regarded as unreliable historical data, and the weight value is 20%; and if the historical data within 2.5 meters around the GPS position of the new source machine and within 5 minutes before and after the same time within 5 days is less than or equal to 1000, the weight value is 0.
In an optional embodiment of the present application, in S200, the historical rate parameters include an average rate and a rate fluctuation rate, and a corresponding connection rate average value and a connection rate variance value are calculated according to the target rate data; and determining the average rate corresponding to the single link according to the connection rate average value, and determining the rate fluctuation rate corresponding to the single link according to the connection rate variance value. Here, MPTCP supports 4 links at most, so four operators are connected at most, and if more than 2 of the 4 links belong to the same operator, for example, two SIM cards of the same operator are inserted into one mobile terminal, the mobile terminal still belongs to an independent link.
In an optional embodiment of the present application, in S300, a ratio of the average rate and the rate fluctuation rate of a single link in all links is multiplied by the weight value to obtain a first ratio; obtaining minimum round-trip delay data by the single link according to a minimum round-trip delay data calling algorithm, and obtaining a second ratio by multiplying the ratio of the minimum round-trip delay data of the single link in the sum of the minimum round-trip demonstration data of all links by the residual value after the weight value is removed; and taking the sum of the first ratio and the second ratio as the distribution load ratio of the single link to determine the distribution load ratio of each link. In the above embodiment, assume that the historical data of the first link has a rate a (in bps), the real-time RTT is i (in milliseconds), and the weight of the historical rate data is w%. Assuming that the historical data of the second link has a rate b (in bps), the real-time RTT is j (in milliseconds), and the weight of the historical data is w%. Suppose that the third link has a historical data rate of c (in bps), a real-time RTT of k (in milliseconds), and a historical data weight of w%. Suppose the fourth link has a historical data rate of d (in bps), a real-time RTT of l (in milliseconds), and a historical data weight of w%. The ratio of the rates of the historical rate data of the four links is a: b: c: d, and the ratio of the real-time RTTs is:
the first link is assigned a duty ratio of:
and the load ratio calculation of the four links is finished by analogy.
In an optional embodiment of the present application, historical data (for example, within 2.5 meters around the GPS and within 5 minutes around 5 days) searched from the cloud server based on the real-time location and the current time of the new mobile terminal exceeds 10000, and the historical data is used as reliable data, and the weight of the historical data is determined to be 80%, and the weight of the RTT is only 20%. Assuming that the first link is a link of a first operator, the average value of the history data is 1Mbps, the real-time RTT is 100ms, the second link is a link of a second operator, the average value of the history data is 500Kbps, the real-time RTT is 50ms, and the real-time RTT shows that the signal of the second operator is good, but the history data shows that the signal of the first operator is good. For a total of two operators, the historical rate ratio is 2: 1, real-time RTT ratio is 1: 2, the ratio allocated to the first link is 2/3 × 80% +1/3 × 20% + 60%, which requires a total of 1000 bytes to be transmitted, the first link transmitting 600 bytes, and the first link transmitting only 333 bytes using the RTT data scheduling algorithm. The precision of load distribution is effectively improved.
In an optional embodiment of the present application, the mobile terminal may match different connection modes based on the load distribution calculation manner, including a speed priority mode and a connection priority mode. In the speed-first mode, at a certain position, the difference between the historical speeds of the two operators is smaller than a preset threshold value, that is, almost no difference exists, and then the MPTCP uses the two increased speeds at the same time. If the difference between the two operator speeds is larger than the preset threshold, i.e. the difference is very large, the low speed is abandoned, because the low speed is used, which may cause "TCP head of line blocking", and the original minimum Round Trip Time (RTT) data scheduling algorithm may retry continuously and cause excessive energy consumption. In the connection priority mode, even if the rate of a certain operator is low, MPTCP still tries to connect continuously because of the "connection priority mode", but after connection, the load is not loaded on the low-speed link.
Embodiments of the present application also provide a computer readable medium, on which computer readable instructions are stored, the computer readable instructions being executable by a processor to implement the foregoing method for a mobile terminal to allocate a link.
