In a general design, taking a game service of a mobile terminal as an example, the relevant characteristics of the game service are as follows: long connections, small data packets, low traffic, low latency requirements, low fault tolerance, and sensitivity to changes in the wireless network environment. Due to the sensing capability range of normal people, when the delay in the game service reaches the level of 100ms, the user can obviously feel the card pause, and the operation is not flexible; when the delay in the game reaches the 200ms level, the operation of the user and the game perception feedback can not be synchronized basically, and the user experience is seriously influenced. As can be seen from the network architecture shown in fig. 1A, the interaction process of the game service data of the mobile phone and the network device includes access network delay from the mobile phone to the network air interface and time consumption for transmitting IP data from the access network to the game server, the interaction process involves interaction between the mobile phone and each network element on the network side, and is affected by the wireless communication environment, the situation is complex, the number of involved relevant variables is large, and the time consumption of the interaction process occupies a large proportion in the overall delay.
In view of the above situation, an embodiment of the present application provides a network handover control method, in which a mobile terminal first obtains a reference ramping step size of transmission power of a preamble configured in a target serving cell, then updates a step size ramping sequence of the transmission power according to the reference ramping step size, and finally performs random access according to the updated power ramping step size sequence. Because the first average climbing amplitude of the updated step climbing sequence is greater than the second average climbing amplitude of the step climbing sequence before updating, when the transmitting power of the lead code corresponding to successful switching is relatively stable, the updated step climbing sequence is obviously used to reduce the transmitting times of the lead code which fails to be switched, further reduce the time consumption of the failure switching, reduce the transmission delay caused by network switching in the data transmission process of the mobile terminal, and improve the real-time property of the data transmission of the mobile terminal.
Embodiments of the present application will be described below with reference to the accompanying drawings.
Referring to fig. 2, fig. 2 is a flowchart illustrating a network handover control method according to an embodiment of the present application, which is applied to a mobile terminal and can be executed by an application processor, a baseband processor, or an SoC of the mobile terminal, as shown in the figure, the network handover control method includes:
s201, the mobile terminal obtains a reference climbing step length of the transmitting power of a lead code configured in a target service cell, wherein the lead code is used for identifying the identity of the mobile terminal when the mobile terminal carries out random access.
The reference ramping step is used for adjusting the transmission power of the preamble in the random access process, and the reference ramping step may be 2dB, 4dB, 8dB, and the like, which is not limited herein, and the purpose of the mobile terminal performing random access is to negotiate with the target serving cell to determine the channel resource as shown in fig. 1D.
S202, the mobile terminal updates the step-size climbing sequence of the transmitting power according to the reference climbing step size, a first average climbing amplitude of the updated step-size climbing sequence is larger than a second average climbing amplitude of the step-size climbing sequence before updating, and step size ranges corresponding to the first average climbing amplitude and the second average climbing amplitude are included in a climbing step size range from an initial climbing step size to the reference climbing step size.
It is understood that the specific implementation manner of the step-up sequence for the mobile terminal to update the transmission power according to the reference step-up step may be various, and is not limited herein.
For example, a specific implementation manner of the mobile terminal updating the step-up sequence of the transmission power according to the reference step-up step may be: the mobile terminal determines at least one climbing step length between an initial climbing step length and the reference climbing step length in a step length climbing sequence before updating; deleting the climbing step length in the at least one climbing step length in the step length climbing sequence before updating to obtain the updated step length climbing sequence. Wherein the number of deleted climb steps is less than or equal to the determined number of the at least one climb step.
For example, assuming that the step climbing sequence before updating is [2,4,6,8,10], where 8 is the reference climbing step, the step climbing sequence after updating may be [2,6,8,10], and it can be seen that the number of transmissions of the step lengths 2 to 8 is reduced from the original 3 times to 2 times, that is, the mobile terminal only needs to transmit 2 times of preambles to successfully access the target serving cell, which shortens the number of transmissions and reduces the time consumption for access failure.
S203, the mobile terminal carries out random access according to the updated power ascending step length sequence.
Taking the LTE system as an example, the random access process includes that the mobile terminal sends a preamble to the network device to which the target serving cell belongs, and the network device sends a Random Access Response (RAR) to the mobile terminal. The mobile terminal sends a preamble to the base station eNodeB to tell the eNodeB that there is a random access request, and at the same time, the eNodeB can estimate the transmission delay between the eNodeB and the mobile terminal and calibrate uplink timing (uplink timing).
The mobile terminal sending preamble specifically comprises the following processes:
and 1, selecting a preamble index.
And 2, selecting PRACH resources for sending the preamble.
And 3, determining the corresponding RA-RNTI.
Procedure 4, determine TARGET RECEIVED POWER PREAMBLE _ RECEIVED _ TARGET _ POWER.
In the process 1, unlike the preamble index in the non-contention based random access, which is designated by the eNodeB, the preamble index is randomly selected by the mobile terminal in the contention based random access. The mobile terminal first determines whether a preamble in group a or group B is selected. If there is preamble group B, and the size of the system message msg3 is larger than the messageSizeGroupA, and the pathloss is smaller than the value A, then group B is selected; otherwise, select group A, numberThe value A is calculated by the formula PCNAX,c-preambernitalized receivedtargetpower-deltapreambemsg 3-messagePowerOffs etGroupB. If msg3 was sent before and the access failed, the preamble used in the re-access attempt should belong to the same group as the corresponding preamble when msg3 was sent for the first time. After the group is determined, the mobile terminal randomly selects a preamble from the group and sets the PRACH Mask Index to 0. For non-contention based random access, the eNodeB allocates a dedicated preamble Index to the mobile terminal to avoid collision and assign a PRACH Mask Index.
In the process 2, based on the PRACH-ConfigIndex, the PRACH Mask Index, and the timing restriction of the physical layer, the mobile terminal may first determine the next available subframe including the PRACH. The PRACH-ConfigIndex specifies the PRACH resources available in the time domain. The PRACH Mask Index defines which PRACH within the system frame a certain mobile terminal can send preamble on. In the random access based on non-contention, the eNodeB can directly designate the mobile terminal to send the preamble on a certain PRACH through the mask, thereby ensuring that no collision occurs with other mobile terminals.
In the process 3, the time-frequency position of the preamble determines the value of the RA-RNTI, and after the mobile terminal sends the preamble, the mobile terminal monitors the corresponding PDCCH according to the RA-RNTI value in the RAR time window.
In procedure 4, the TARGET RECEIVED POWER PREAMBLE _ RECEIVED _ TARGET _ POWER of the PREAMBLE is calculated by the following formula: preambelnitial receivedtargetpower + DELTA _ preable + (preable _ transition _ COUNTER-1) × powerRampingStep.
Wherein the preamble interference receivedtargetpower is the initial power of the preamble that the eNodeB expects to receive. DELTA _ PREAMBLE is associated with PREAMBLE format, and its value is Table 7.6-1 at 36.321. And the power ramping step, powerRampingStep, is the transmit power that is increased for the next access after each access failure. And the actual transmit power P of the preamblePRACHIs calculated by the formula
PPRACH＝min{PCMAX，c(i)，PREAMBLE_RECEIVED_TARGET_POWER+PLc}_[dBm]
Wherein, PCMAX,c (i)Is the maximum output power, PL, configured by the mobile terminal on the subframe i of the PCellcThe downlink path loss is obtained by the mobile terminal through measuring a Cell-specific reference signal of the PCell.
After the mobile terminal sends the preamble, the mobile terminal monitors the PDCCH in an RAR time window (RA Response window) to receive RAR corresponding to the RA-RNTI. If the RAR replied by the eNodeB is not received within the RAR time window, the random access procedure is considered to fail. If the access process fails and the maximum random access attempt time preambleTransMax is not reached, the mobile terminal will increase the power powerRampingStep to send the next preamble based on the last transmission power so as to improve the probability of successful transmission. The mobile terminal determines whether the RAR which the mobile terminal wants is successfully received or not through the RA-RNTI and the preamble index which are carried by the RAR, and then carries out subsequent processing.
It can be seen that, in the embodiment of the present application, the mobile terminal first obtains the reference ramp step size of the transmission power of the preamble configured in the target serving cell, then updates the step size ramp sequence of the transmission power according to the reference ramp step size, and finally performs random access according to the updated power ramp step size sequence. Because the first average climbing amplitude of the updated step climbing sequence is greater than the second average climbing amplitude of the step climbing sequence before updating, and the step range corresponding to the first average climbing amplitude and the second average climbing amplitude is included in the climbing step range from the initial climbing step to the reference climbing step, under the condition that the transmitting power of the lead code corresponding to the successful switching is relatively stable, the number of times of transmitting the lead code which fails to be switched can be obviously reduced by using the updated step climbing sequence, the time consumption of the switching failure is further reduced, the transmission interruption time delay caused by network switching in the data transmission process of the mobile terminal is reduced, and the real-time performance of data transmission of the mobile terminal is improved.
In one possible example, the serving cell currently accessed by the mobile terminal and the target serving cell are serving cells in the same communication system.
The currently accessed serving cell and the target serving cell may be serving cells in an LTE system, or serving cells in a new air interface system such as 5G, which is not limited herein.
In one possible example, the mobile terminal updating the step-up sequence of transmit powers according to the reference step-up step size includes: the mobile terminal determines the highest transmission delay which can be borne by the data service of the mobile terminal; and updating the step-up sequence of the transmitting power according to the highest transmission delay and the reference step-up step.
The maximum transmission delay may be the same or different for different data services of the mobile terminal, and may be determined comprehensively specifically according to the actual state of the foreground operating interface and the user experience, and form a mapping relationship set to be stored in the mobile terminal in advance.
In specific implementation, the mobile terminal may determine the sending of the single preamble and the RAR in the detection time window until determining the reference time consumption of the processing procedure of the random access failure, and may determine, by combining with the determined highest transmission delay, that the random access failure is allowed at most several times, that is, the sending times.
Therefore, in this example, the mobile terminal can determine the highest transmission delay that can be borne by the current data service, and comprehensively update the step-up sequence of the transmission power of the preamble in combination with the reference step-up sequence, so as to ensure that the immediate access process of the mobile terminal does not excessively improve the transmission delay of the current data service as much as possible, which is beneficial to improving the real-time performance and efficiency of data transmission of the mobile terminal.
In this possible example, the updating, by the mobile terminal, the step-up sequence of the transmit power according to the highest transmission delay and the reference step-up step includes: the mobile terminal determines the highest frequency of random access failure which can be borne by the data service according to the highest transmission delay; and updating the step climbing sequence of the transmitting power according to the maximum times and the reference climbing step length, wherein the climbing times corresponding to the updated reference climbing step length are less than or equal to the maximum times.
Still taking the game data service as an example, the highest transmission delay that the game data service can endure is 100ms, and the transmission delay of the current game data service is within 10ms, the reference climbing step length is 8dB, the initial climbing step length is 2dB, the step length climbing sequence before updating is [2,4,6,8,10], the mobile terminal determines the RAR in a single lead code sending and detecting time window until the reference time consumption of the processing process of the random access failure is determined to be 40ms, then, the mobile terminal can determine that the highest frequency of the random access failure which can be borne by the game data service is 2 times, and then the step length climbing sequence for updating the transmission power of the lead code according to the highest frequency of 2 times and the reference climbing step length of 8dB is [2, X,8,10] or [2,8,10], and X is an integer which is less than 8 and is more than 2.
Therefore, in this example, the mobile terminal can update the step-size climbing sequence according to the highest number of random access failures that can be borne by the data service and the reference climbing step size, so that the time consumed for successful random access corresponding to the updated step-size climbing sequence is less than the highest transmission delay that can be borne by the data service, and thus, the stability and the real-time performance of data transmission of the mobile terminal are improved.
In one possible example, the mobile terminal obtaining a reference ramping step size of the transmission power of the preamble configured by the target serving cell includes: the mobile terminal determines a climbing step length corresponding to the current position of the mobile terminal in a climbing step length set as the reference climbing step length by inquiring a preset climbing step length set, wherein the climbing step length set comprises a corresponding relation between a position and the climbing step length.
When the mobile terminal is in different areas of the coverage area of the target serving cell, the reference climbing step length in the random access process of the mobile terminal is generally different, so that a mapping relation between different areas or positions and the reference climbing step length needs to be established, and the reference climbing step length can be acquired more conveniently, quickly and accurately. The processing efficiency is improved.
In one possible example, the serving cell currently accessed by the mobile terminal and the target serving cell are serving cells in a heterogeneous communication system.
The currently accessed serving cell may be a serving cell in an LTE system, and the target serving cell may be a serving cell in a new air interface system such as a 5G system, which is not limited herein.
In one possible example, the foreground of the mobile terminal runs a target application, and the target application may be a game application, a video application, or the like, which is not limited herein. Illustratively, the running interface of the target application is a multi-user online battle arena (MOBA) scene interface.
In specific implementation, the mobile terminal may analyze a plurality of data packets through sampling by the baseband processor, identify an MOBA scene of a target application program running in the foreground through attributes such as format of the data packets, and acquire scene information sent by the foreground application program through the application processor, so that the operating system can timely know the MOBA scene of the target application program running in the foreground, which is not limited uniquely here. That is to say, the triggering condition for the mobile terminal to execute the step S201 may be that the mobile terminal detects that the current operation scene is the MOBA scene, so as to implement the exclusive optimization control for the MOBA scene.
Therefore, in the example, the mobile terminal only performs identification and exclusive optimization control on the MOBA scene, so that resource balance is facilitated, and cruising ability is improved.
