Embodiment
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, the embodiments of the present invention are explained in detail.But, persons of ordinary skill in the art may appreciate that in the each execution mode of the present invention, in order to make reader understand the application better, many ins and outs are proposed.But, even without these ins and outs and the many variations based on following execution mode and amendment, also can realize the each claim of the application technical scheme required for protection.
The first execution mode of the present invention relates to the time synchronization method of each protocol module in a kind of multimode terminal, the method is without benchmark timing, comprise the software timing system that each protocol module is ununified, or the benchmark all can read without each protocol module on hardware timing, the timeslice information that holotype protocol module is distributed is converted to the timing information that corresponding auxiliary mode protocol module can be identified.Idiographic flow as shown in Figure 1, comprises following steps:
Table 1
| Parameter | Explanation |
| gap_start | The original position of distributing GAP, represents with holotype timing information |
| gap_length | Distribute the length of GAP |
| interrupt_offset | GAP interrupts distributing the distance of GAP original position |
Specifically, as shown in Figure 2, holotype protocol module is Master RAT, auxiliary mode protocol module is Slave RAT, Master RAT distributes to the free time sheet information (follow-up general designation GAP information) of Slave RAT and transmits by message MASTER_ALLOC_GAP_IND, sending after MASTER_ALLOC_GAP_IND, Master RAT also needs to send a GAP to Slave RAT and interrupts (follow-up with GAP_INTERRUPT represent).That is to say, holotype protocol module, getting after auxiliary mode protocol module sends the fixed time of GAP interruption, sends GAP assignment messages to auxiliary mode protocol module; In the fixed time that sends GAP interruption, holotype protocol module sends GAP to auxiliary mode protocol module and interrupts.
The specific descriptions that comprise parameter in GAP assignment messages (being MASTER_ALLOC_GAP_IND) as shown in Figure 3, in figure, the 301st, the fixed time point of transmission GAP terminal, the 302nd, the original position of the distribution GAP representing with holotype timing information, the 303rd, the length of distributing GAP, the 304th, GAP interrupts distributing the distance of GAP original position.As seen from the figure, GAP assignment messages sent before GAP interrupts; GAP interrupts sending before the original position of GAP.That is to say, Master RAT is knowing that it can send after GAP_INTERRUPT at gap_int_timing (representing with Master RAT timing information), send MASTER_ALLOC_GAP_IND to Slave RAT, wherein comprised gap_start (representing with Master RAT timing information), these three parameters of gap_length, interrupt_offset.Arrive after fixed time gap_int_timing, Master RAT sends and interrupts GAP_INTERRUPT to Slave RAT.
Specifically, under auxiliary mode protocol module records, receive the time point that GAP interrupts, and represent to send the fixed time that GAP interrupts with the timing information of auxiliary mode protocol module, be designated as gap_int_slave_timing; Gap_int_slave_timing is added to interrupt_offset, obtain the concrete time point gap_start_slave that holotype protocol module distributes GAP; Wherein, gap_start_slave represents with the timing information of auxiliary mode protocol module.That is to say, Slave RAT records the time point of receiving this interruption, and namely the timing information of gap_int_timing after representing with Slave RAT timing information, is designated as gap_int slave_timing.Gap_int_slave_timing is added after interrupt_offset, can know that Master RAT distributes the particular location gap_start_slave(Slave RAT timing information of GAP to represent).
By above two steps, holotype sends GAP assignment messages and GAP interruption to auxiliary pattern, auxiliary mode record is received the time point that GAP interrupts, and with holotype GAP assignment messages in the GAP that carries interrupt distributing the distance of GAP original position to be added, can calculate the concrete time point that represents holotype distribution GAP with the timing information of auxiliary pattern, thereby without unified software timing system, also without the benchmark timing can read on hardware, the GAP information with Master RAT timing information represents that just Master RAT can be distributed is converted into the discernible GAP information of Slave RAT, realize the GAP message of holotype to the conversion of the timing information of auxiliary pattern, make the solution of the present invention complexity low, realize simple, the scheme being beneficial on different hardware platforms is transplanted.
Present embodiment is interrupted by twice GAP assignment messages of transmission and GAP, and relatively the timing information difference of holotype and the timing information difference of auxiliary pattern between twice, the timing that is very easy to judge auxiliary pattern safeguards whether there is deviation, and in the time there is deviation, utilize the deviation between timing information difference to carry out the adjustment regularly of auxiliary pattern, realize the calibration of auxiliary pattern timing, further make the solution of the present invention complexity low, realize simply, the scheme being beneficial on different hardware platforms is transplanted.
Specifically, step 103, judges the timing of auxiliary pattern safeguards whether there is deviation, if the deviation of existence performs step 104; Otherwise, finish this timing adjustment;
That is to say, have no progeny receiving in twice GAP, auxiliary mode protocol module is obtained the holotype timing information gap_start_0 in GAP assignment messages for the first time, and corresponding auxiliary pattern timing information gap_start_slave_0 and the holotype timing information gap_start_1 in GAP assignment messages for the second time, and corresponding auxiliary pattern timing information gap_start_slave_1;
Difference delta1 between comparison gap_start_1 and gap_start_0 between difference delta0 and gap_start_slave_1 and gap_start_slave_0;
If delta0 and delta1 are inconsistent, judge that timing information that auxiliary pattern is now safeguarded and the timing information of holotype have deviation, and utilize the difference of delta0 and delta1 to adjust the timing of auxiliary pattern.In the present embodiment, can be according to the difference of delta0 and delta1, the hardware frame of directly adjusting auxiliary pattern interrupts.Such as, 10ms while supposing that delta0 calculates, 10.5ms when delta1 calculates, illustrate so the timing of current auxiliary pattern inclined to one side 0.5ms, the hardware frame of directly adjusting auxiliary pattern interrupts realizing the timing alignment of auxiliary pattern, without extra interface, to existing Software Protocol Stack require lowly, realize simple.
As shown in Figure 4, in figure, the 401st, gap_start_0, the 402nd, gap_start_slave_0, the 403rd, gap_start_1, the 404th, gap_start_slave_1.As seen from the figure, receiving after twice GAP_INTERRUPT, Slave RAT knows main and auxiliary pattern timing information gap_start_0, the gap_start_slave_0 of GAP0 and main and auxiliary pattern timing information gap_start_1, the gap_start_slave_1 of GAP1.In theory, gap_start_1 should be the same with the difference (delta1) of gap_start_slave_1 and gap_start_slave_0 with the difference (referred to as delta0) of gap_start_0.Once there is different situation, illustrate that the timing information that auxiliary pattern is now safeguarded has deviation, so just can utilize the difference of delta0 and delta1 to adjust the timing of auxiliary pattern.
