Embodiment
Below in conjunction with each accompanying drawing, embodiment of the present invention technical scheme main realized to principle, embodiment and the beneficial effect that should be able to reach is at length set forth.
As shown in Figure 2, be the network reselection method flow chart of multimode terminal in the embodiment of the present invention, its concrete handling process is as follows:
Step 21, multimode terminal determines that self is not more than the first state of the first defined threshold in movement rate;
The embodiment of the present invention proposes, if the movement rate of multimode terminal is not more than the first defined threshold, this multimode terminal is in the first state, if the movement rate of multimode terminal is greater than the first defined threshold, this multimode terminal is in the second state, wherein the multimode terminal in the first state may be static, also may carry out low rate motion.
Multimode terminal determines that self can be, but not limited to by following process implementation in the first state or the second state:
Current point in time is T1, the time point that the multimode terminal last time is carried out gravity treatment between supported network is T2, first to obtain time point be self movement rate in time period between T1 and T2 to multimode terminal, if the movement rate obtaining is not more than the first defined threshold, can think that self is in the first state, if the movement rate obtaining is greater than the first defined threshold, can think that self is in the second state.
Wherein, can be, but not limited to arrange motion sensor in multimode terminal, gathered the movement rate of multimode terminal by motion sensor.
Motion sensor is in the time gathering movement rate, can be according to the movement rate of fixing sampling time point sampling multimode terminal, for example, arrange and be spaced apart 0.1 second between sampling time point, motion sensor will be every the movement rate of 0.1 second sampling multimode terminal so, multimode terminal can obtain in the above-mentioned time period, the sampling movement rate that motion sensor obtains at each sampling time point sampling, and then the mean value of each sampling movement rate of calculating acquisition, the mean value of determining, is the movement rate of multimode terminal within the above-mentioned time period.
In the embodiment of the present invention, if multimode terminal transfixion, think that multimode terminal is in the first state, if multimode terminal carries out the motion of low rate, also can think that this multimode terminal is in the first state, except the method for above-mentioned comparing motion speed and the first defined threshold size, can also realize by the sensitivity of adjustment movement transducer in advance, make motion sensor carry out low rate while moving at multimode terminal, the movement rate sampling is also zero, now as long as the movement rate that motion sensor samples is zero, confirm that multimode terminal is in the first state, as long as the movement rate that motion sensor samples is non-vanishing, confirm that multimode terminal is in the second state.
Step 22, obtains number of times accumulative total, carry out continuously gravity treatment between supported network in the time of the first state;
In the embodiment of the present invention, gravity treatment counter is set in advance in multimode terminal, in the time that multimode terminal initially carries out network reselection, start gravity treatment counter, if multimode terminal carries out gravity treatment between supported network in the first state, gravity treatment counter adds 1, if multimode terminal carries out gravity treatment between supported network in the second state, gravity treatment counter clear 0, multimode terminal directly reads the counting of gravity treatment counter, thereby obtains the number of times that carries out continuously gravity treatment in the time of the first state between supported network.
For example current gravity treatment rolling counters forward is 0, multimode terminal resides in network A, if when multimode terminal reselects to network B from network A in the first state, gravity treatment counter adds 1, when if multimode terminal reselects to network A again from network B in carrying out the second state, gravity treatment counter clear 0.
In the embodiment of the present invention, it is two that the network that multimode terminal is supported can be, but not limited to, and can be also multiple, and multimode terminal carries out network reselection in supported multiple networks.
Step 23, has reached the second defined threshold if determine the number of times of acquisition,, in the time meeting network reselection condition, selects a network between supported network;
If carrying out continuously the number of times of network reselection under the first state, multimode terminal reaches the second defined threshold, can think that ping-pong reselection may occur this multimode terminal, in order to prevent the generation of ping-pong reselection, should allow multimode terminal in one network resident, stop multimode terminal to continue to carry out network reselection under the first state, therefore multimode terminal has reached the second defined threshold at the number of times of determining acquisition, and while now meeting network reselection condition, in the network of supporting, select a network to carry out resident.
Multimode terminal can directly be selected now resident network, for example, multimode terminal reselects to network A by network B, now gravity treatment counter be counted as 4, the second defined threshold is 4, the number of times of determining acquisition has reached the second defined threshold, and, in the time meeting network reselection condition, multimode terminal selects network A resident.
Network reselection condition can be, but not limited to for: the signal strength signal intensity that obtains objective network by isosystem measurement is greater than gravity treatment thresholding.
In addition, it is resident that multimode terminal can also select a good network of network quality to carry out in two networks, is specially:
Multimode terminal in the time carrying out network reselection at every turn, all can receive the network reselection Indication message that the base station in objective network sends, the embodiment of the present invention proposes, the base station of objective network is at every turn in the time sending network reselection Indication message, all carry the positional information of this base station self, multimode terminal is in the time that the first state carries out gravity treatment between supported network, the positional information of the base station that storing received arrives, multimode terminal is in the time that the second state carries out gravity treatment between supported network, delete the positional information of the base station of storage, the positional information that is to say the base station of multimode terminal storage is multimode terminal storage in the time that the first state carries out gravity treatment continuously between supported network, the positional information of storage comprises the positional information of the base station in supported each network.
In addition, multimode terminal is carrying out before network reselection at every turn, all can carry out isosystem measurement to objective network, the signal strength signal intensity of measurement target network, the embodiment of the present invention proposes, multimode terminal is in the time that the first state carries out gravity treatment between supported network, store the signal strength signal intensity of the objective network that this gravity treatment pre-test arrives, multimode terminal is in the time that the second state carries out gravity treatment between supported network, delete the signal strength signal intensity of storage, the signal strength signal intensity that is to say multimode terminal storage is multimode terminal storage in the time that the first state carries out gravity treatment continuously between supported network, the signal strength signal intensity of storage comprises at least one signal strength signal intensity of supported each network.
Multimode terminal is selecting network to carry out when resident, obtain the positional information of the base station in each network of supporting of storing, and the signal strength signal intensity of each network of supporting, multimode terminal starts location survey, determine the current location information of self, then according to the signal strength signal intensity, the positional information of base station and the current location information of determining that obtain, in supported network, select a network.
Wherein multimode terminal, according to the signal strength signal intensity, the positional information of base station and the current location information of determining that obtain, is selected a network in supported network, can be, but not limited to by following process implementation:
First according to the signal strength signal intensity obtaining, determine respectively the average signal strength of the network of supporting, then the average signal strength of definite each network of supporting is poor, if the difference of the average signal strength of determining is greater than the 3rd defined threshold, select the network that average signal strength is larger, if the difference of the average signal strength of determining is not more than the 3rd defined threshold, according to the positional information of the base station obtaining and the current location information of determining, distance between base station in each network of determining this multimode terminal respectively and support, select and self network apart from maximum place, base station.
Wherein, if the network that multimode terminal is supported is two, multimode terminal is directly determined the poor of average signal strength between two networks, if the network that multimode terminal is supported is multiple, multimode terminal can calculate poor between maximum average signal strength and minimum average signal strength, poor using the poor average signal strength as supported each network of determining.
Prior art also can be carried out gravity treatment judgement according to the positional information of multimode terminal, but whether multimode terminal no matter need to or not to carry out network reselection, all need start by set date location survey, this has just caused the measurement result of a lot of location surveys can not be applied to network reselection, waste the more processing resource of multimode terminal, in the embodiment of the present invention, multimode terminal is only selecting network to carry out just starting when resident location survey, then select network resident according to positioning measurement result, this has just saved the more processing resource of multimode terminal.
Step 24, was determining self before the second state, resided in the network of selecting, and multimode terminal stops at and between supported network, carries out network reselection.
If follow-up multimode terminal is determined self in the second state by motion sensor, in the time meeting network reselection condition, between supported network, carry out gravity treatment, that is to say, the condition that multimode terminal starts network reselection is that two-forty motion has occurred multimode terminal, multimode terminal starts after network reselection, and gravity treatment counter is clear 0, deletes positional information and the signal strength signal intensity of the base station of storage simultaneously.
From above-mentioned processing procedure, in embodiment of the present invention technical scheme, multimode terminal determines that self is in the first state, wherein multimode terminal in the time that movement rate is not more than the first defined threshold in the first state, if accumulative total, the number of times that carries out continuously gravity treatment in the time of the first state between supported network has reached the second defined threshold, in the time meeting network reselection condition, between supported network, select a network, determining self before the second state, reside in the network of selecting, wherein multimode terminal in the time that movement rate is greater than the first defined threshold in the second state, therefore, when the number of times that carries out continuously network reselection in the first state when multimode terminal reaches stipulated number, thinking may generation meeting ping-pong reselection, it is resident that now multimode terminal is selected a network in supported network, keep the first state if follow-up, do not carry out network reselection even if meet network reselection condition yet, continue to reside in the network of selecting, this has just been avoided the problem of multimode terminal generation ping-pong reselection, ensure the regular traffic processing of multimode terminal, avoid off-grid, the situations such as call drop, also saved the more processing resource of multimode terminal and network.
