Description
Technical Field
The invention relates to the field of mobile communication, in particular to a method for improving the delay of a mobile phone terminal initiating an unstructured supplementary service data based on an IMS network.
Background
In current practical use, a terminal supporting IMS is found, the USSI service based on the PS domain initiated actively has higher failure probability, and after USSI failure, USSD retry is carried out from the UE CSFACK to the CS domain, so that the USSD service processing time is prolonged.
For whether the IMS network supports USSI service which is actively initiated by the IMS terminal and is sent to the IMS network, the IMS terminal can not know the USSI service. If the USSD service is triggered by the operation of the IMS terminal, the USSI service is directly initiated by the IMS terminal, and the USSI service initiated by the IMS terminal actively has lower success probability because the IMS terminal does not know the service capability of the IMS network in advance, so that the USSI service in the PS domain fails all the time when the IMS terminal initiates the USSI service in the IMS network which does not support the USSI. Furthermore, when the IMS network wishes to complete the USSD service in the 2G network or the 3G network, if the IMS terminal considers that the IMS network supports the USSI service, the IMS terminal cannot properly complete the USSD service. The above results will seriously affect the business process and user experience.
Patent CN 201910859975-signaling sending and receiving method and apparatus, storage medium, network device, and terminal, provide a signaling receiving method, which includes: sending an SIP registration message; and receiving a SIP registration response, wherein the SIP registration response comprises indication information which is used for indicating whether the IMS network supports USSI service.
This patent has the following problems: 24.390 Protocol 4.5.3 describes that, when the UE does not support CS, or supports CS and IMS, the UE obtains the setting condition of 24.391.4 ussd \ucs _domain _onlyby a supplementary service query method, so as to determine whether the UE can initiate user initiated USSI. Moreover, the IMS network system needs to be upgraded, the IMS network is mature, the upgrading difficulty is high, and the method does not bring any improvement aiming at the area where the IMS network system is not upgraded. The patent requires modification of the SIP registration process and the network side needs upgrading. If the network side is not upgraded, the UE cannot know whether the network side is not supported or the network version is not upgraded. The patent has the advantages that the SIP registration process can know whether the network supports the UE to initiate USSI, and the USSD service does not need to be specially inquired for the supplementary service capability. In practice, however, supplementary services are of a wide variety, as well as other services, such as caller barring, etc. After the UE is powered on and before the UE performs the MO service, it is generally required to check a supplementary service setting condition at the network side.
Disclosure of Invention
The invention provides a method for improving the delay of a mobile phone terminal initiating an Unstructured Supplementary Service Data (USSD) service based on an IMS network, which can reduce the total time consumption of the whole USSD service and improve the user experience.
The technical problem to be solved by the invention is realized by the following technical scheme:
the invention provides a method for improving the delay of a mobile phone terminal initiating an unstructured supplementary service data based on an IMS network, which comprises the following steps:
step 1, starting up, and initiating a new UE initiated USSI by the UE;
step 3, judging whether the UE initiated USSI is successful; if the UE initial USSI service succeeds, the total successful times of the UE initial USSI service in T1 time from the startup are recorded as F2 plus 1, the successful times of the UE initial USSI service in T2 time from the startup are recorded as K1 plus 1, and the step 5 is executed; if the UE fails, recording the total failure times of the initial USSI service of the UE in T1 time from starting up by adding 1 to F1, and recording the failure times of the initial USSI service of the UE in T2 time from starting up by adding 1 to S1;
step 4, judging whether USSD succeeds after UE CSfack; if the operation is successful, recording the successful total times of the UE initiated USSD + CS service in T1 time from the startup by adding 1 to F4, and recording the successful times of the UE initiated USSD + CS service in T2 time from the startup by adding 1 to K2; if the operation fails, recording the total failure times of the UE initiated USSD + CS service in T1 time from starting up by adding 1 to F3, and recording the failure times of the UE initiated USSD + CS service in T2 time from starting up by adding 1 to S2;
step 6, judging whether the timer T2 is overtime or not; if not, returning to the step 3;
step 7, judging whether S1/(K1 + S1) >80% and S2/(K2 + S2) <50% are true or not; if yes, enabling T3 and starting a timer T3+ Tn; if not, executing the step;
step 8, initiating USSD and selecting a USSD + CS mode;
step 9, judging whether T3+ Tn is overtime or not after USSD is finished; if the time is out, T3 is forbidden, and the T3+ Tn timer is stopped; if not, returning to the step 8;
step 10, judging whether T1 is overtime or not; restarting the T1 timer if the time is out; and starting a T2 timer if the time is not over.
Preferably, after the T1 is overtime, the success rate of USSD + CS is judged, and if the success rate of USSD + CS is high, tn is prolonged.
Preferably, after T1 is overtime, the USSI failure rate is judged to be high or low, and Tn is shortened when the USSI failure rate is low.
Preferably, K1, K2, S1, S2 are reset to 0 after the T2 period ends.
Preferably, the USSD + CS success rate is high, meaning F4/(F2 + F4) > 75% and (F3 + F4)/N1 > 40%.
Preferably, the specific method for extending Tn is that new Tn = Tn + T3 × 5% under the condition of original Tn = 0; at the original Tn >0, new Tn = Tn + (Tn × 10%).
Preferably, the USSI failure rate is low, meaning F1/(F1 + F3) <20% and (F1 + F2)/N1 > 50%.
Preferably, the specific method for shortening the Tn is that under the condition that the original Tn is greater than 0, the new Tn = Tn- (Tn × 15%); on condition of the original Tn =0, then T3 is reset to the initial value and T3 is disabled until re-enabled.
Preferably, if S1/(K1 + S1) <20% and S2/(K2 + S2) >50% after the end of the T2 period, the T3 TIMER setting is disabled and T3 is disabled if T3 TIMER is in the enabled state.
The invention has the beneficial effects that: for the condition that the network has a temporary fault or abnormal load continuously in a certain period of time, the USSI is forbidden first, so that the problem that the user initiatedUSSI fails continuously and the UE tries repeatedly to waste time can be avoided. Therefore, the total time consumption of the whole USSD service is reduced, and the user experience is improved.

UE initiated USSI + USSD service statistics total unit time TIMER (TIMER) T1, UE initiated USSI service failure statistics TIMER T2 (T2 < T1), UE initiated USSI service failure disabled TIMER T3 (T3 < T1), and UE initiated USSD + CS service dynamic balance optimization TIMER Tn (Tn > 0).
The total number of times of UE initiated USSI + USSD over CS service in T1 time from startup is recorded as N1, the total number of times of failure of UE initiated USSI service in T1 time from startup is recorded as F1, the total number of times of success of UE initiated USSI service in T1 time from startup is recorded as F2, the total number of times of failure of UE initiated USSD + CS service in T1 time from startup is recorded as F3, and the total number of times of success of UE initiated USSD + CS service in T1 time from startup is recorded as F4.
The number of times of success of the initial USSI service of the UE within the time T2 from the start-up is recorded as K1, the number of times of success of the initial USSD + CS service of the UE within the time T2 from the start-up is recorded as K2, the number of times of failure of the initial USSI service of the UE within the time T2 from the start-up is recorded as S1, and the number of times of failure of the initial USSD + CS service of the UE within the time T2 from the start-up is recorded as S2.
N1, F2, F3, F4, K1, K2, S1, S2 may be cleared by the following:
1. after the UE is turned on or turned off or restarted;
2. after the UE is plugged in and pulled out of the card;
3. after the UE is subjected to factory recovery setting;
4. t2 is overtime.
The UE will clear Tn only in both cases 2, 3 and set T3 to an initial value. K1, K2, S1, S2 are reset to 0 only after T2 times out.
The UE initiates a new UE initiated USSI.
Starting up;
UE initiated USSI；
turn on T1 and the UE will be N1 + +;
starting T2;
if it is not
If the UE initiated USSI succeeds, F2+ +, K1+ +;
if the UE initiated USSI fails, F1+ +, S1+ +;
if it is used
If USSD succeeds after UE CSfack, F4+ +, K2+ +;
if USSD fails after UE CSfack, F3+ +, S2+ +;
and initiating the service UE initiated USSI again.
The above operation is cycled through the T2 period until the end of the T2 period time.
After the T2 period is calculated, if S1/(K1 + S1) >80% and S2/(K2 + S2) <50%, enabling T3 TIMER setting, starting T3+ Tn (Tn is initialized to 0), performing USSD service in the T3+ Tn period, selecting the USSD + CS mode until the T3+ Tn is overtime, starting the T2 again after the T3+ Tn is overtime, returning to the USSI mode again, and repeating the steps.
If S1/(K1 + S1) <20% and S2/(K2 + S2) >50% after the T2 period ends, the T3 TIMER setting is disabled and T3 is disabled if T3 TIMER is in the enabled state.
After the T2 period is over, K1K 2S 1S 2 is reset to 0.
The above steps are repeated until T1 times out, at which time the calculation is as follows:
if F4/(F2 + F4) > 75% and (F3 + F4)/N1 > 40%, indicating that USSD + CS success rate is high, tn is extended:
if Tn =0, tn = Tn + T3 × 5%;
if Tn >0, tn = Tn + (Tn × 10%).
Shorten Tn if F1/(F1 + F3) <20% and (F1 + F2)/N1 >50% indicates a low USSI failure rate:
if Tn >0, tn = Tn- (Tn × 15%);
if Tn =0, T3 is reset to the initial value and T3 is disabled until re-enabled.
In the next T1 cycle, T3 = T3+ Tn is set, and the mode selection and cycle adjustment of USSD service are continued.

And after the T1 is overtime, judging the USSD + CS success rate, and if the USSD + CS success rate is high, prolonging Tn. USSD + CS success rates were high, meaning F4/(F2 + F4) > 75% and (F3 + F4)/N1 > 40%. The specific method for prolonging the Tn is that under the condition of original Tn =0, the new Tn = Tn + T is 3 x 5%; at the original Tn >0, new Tn = Tn + (Tn × 10%). And after the T1 is overtime, judging the USSI failure rate, and if the USSI failure rate is low, shortening Tn. USSI failure rate was low, meaning F1/(F1 + F3) <20% and (F1 + F2)/N1 > 50%. The specific method for shortening Tn is that under the condition that the original Tn is greater than 0, the new Tn = Tn- (Tn x 15%); on condition of the original Tn =0, then T3 is reset to the initial value and T3 is disabled until re-enabled.
