Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described.
Should be clear and definite, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
As shown in Figure 1, the method for the network registry that the embodiment of the invention provides based on UE, may further comprise the steps:
Step 101, UE writes down the frequency of failure of the base station of registration first sub-district, and the frequency of failure of the base station of described registration first sub-district is for the frequency of failure or the continuous retry of the base station of registration first sub-district are registered the frequency of failure of the base station of first sub-district continuously.
In this step, the frequency of failure that is write down can be for registering the frequency of failure of the base station of first sub-district continuously, perhaps register the frequency of failure of the base station of first sub-district for continuous retry, be understandable that, the frequency of failure that the frequency of failure of the base station of continuous registration first sub-district is registered the base station of first sub-district than continuous retry is Duoed 1 time, suppose that UE fails to succeed in registration for 5 times in the base station of registration first sub-district continuously, then the frequency of failure of the base station of the continuous registration of UE first sub-district is 5 times, in these the 5 times registrations, the back is for 4 times to attempt registration after the failure of the base station of the 1st registration first sub-district again, and promptly to register the frequency of failure of the base station of first sub-district be 4 to the continuous retry of UE.
Step 102, if the described frequency of failure reaches stipulated number, the described UE base station of introversive other sub-district except that the base station of described first sub-district at the appointed time initiates registration.
When UE needs network registry, UE will select a sub-district to carry out network registry according to protocol algorithm, in the embodiment of the invention, this sub-district will be referred to as first sub-district.Concrete, UE will send connection request (ATTACH REQUEST) to the base station of first sub-district, if do not receive the response of the base station of first sub-district within a certain period of time, it is registration failure, UE can attempt registration process again, promptly select a sub-district and initiate registration according to protocol algorithm again, if under situations such as UE is not moved, when this sub-district that UE reselects may still be first sub-district, UE initiates registration with retry to the base station of first sub-district, in repeatedly continuous retry registration process, UE may all select the base station of first sub-district to register.
Need to prove that in embodiments of the present invention, the base station of sub-district means the base station of sub-district ownership, UE to the sub-district initiate registration, UE carries out the sub-district registration and UE registration sub-district refers to that all UE initiates registration to the base station of sub-district ownership.
With network base station BS-A described in the background technology and BS-B is example, when UE carries out network registry, because the transmitting power of BS-B is better than BS-A, the signal that UE receives BS-B is better than BS-A, therefore, when UE carries out network registry, under situations such as UE is not moved, all select BS-B to carry out network registry according to protocol algorithm UE at every turn, but because BS-B is far away apart from UE, can't receive the register requirement that UE sends, promptly each UE registration BS-B all fails.
Register first sub-district for fear of the retry that UE does not stop, guarantee that effectively UE can successfully carry out network registry, in the embodiment of the invention, in step 101, the frequency of failure of the base station of record registration first sub-district, for example, write down the frequency of failure of continuous retry registration BS-B, when this frequency of failure reaches stipulated number, UE will no longer initiate registration to the base station of first sub-district, and in step 102, select at the appointed time to initiate registration to the base station of other sub-districts except that the base station of first sub-district, therefore, can guarantee effectively that UE is registered to available network, has obviously promoted user experience.And the method for this network registry of UE is not subjected to the restriction of network design, under any network design, can guarantee effectively that all UE is registered to available network, has strengthened the flexibility that network is arranged net.
Optionally, described stipulated number is not limit, and can be provided with arbitrarily, for example is 1 time, 2 times, 3 times or 4 inferior.At existing 3GPP (The 3rd Generation Partnership Project, third generation partner program) stipulates among the TS24008, if registration failure for the first time, be that ATTACH REQUEST does not have response in special time, the trial that UE can initiate to re-register, it is the retry registration, attempt four times at most, after attempting equal registration failure four times, UE can stop the trial of ATTACH, and enter the PLMN-SEARCH pattern, under the PLMN-SEARCH pattern, periodically initiate web search and registration process.For with 3GPP standard compatibility, preferably, during the frequency of failure of the base station that if the frequency of failure of the base station of registration first sub-district of writing down in the step 101 is continuous retry registers first sub-district, described stipulated number can be set to 4 times, register the base station failure 4 times of first sub-district at the continuous retry of UE after, UE enters the PLMN-SEARCH pattern, and under this pattern, UE still can initiate to search net and registration process, and promptly UE attempts other sub-districts of registration in the described stipulated time.Obviously, if the frequency of failure of base station of registration first sub-district of record be that described stipulated number can be set to 5 times when registering the frequency of failure of base station of first sub-district continuously in the step 101.
Need to prove that the described stipulated time can be limited duration, can be unlimited duration yet, the present invention does not do qualification to this.Because UE has mobility, when UE is moved, first sub-district that originally can't register may be changed the optimum subdistrict that current UE can be registered into before, therefore, the described stipulated time can preferably be set to limit, so that through after the described stipulated time, UE can initiate registration to first sub-district, to guarantee effectively that further UE successfully carries out the sub-district registration, guarantee that effectively UE can choose optimum subdistrict and carry out network registry, improve the reliability of enter the internet registration and the communication quality between UE and the sub-district, promote user experience.
Preferable, the described stipulated time can be 60 to 120 seconds, for example is 90 seconds.Optionally, the described stipulated time can reach the moment of stipulated number from the described frequency of failure, can also be from any time after the described frequency of failure reaches moment of stipulated number, and the present invention does not do qualification to this.
Further, in one embodiment of the invention, if the frequency of failure of the base station of the described registration of UE first sub-district reaches stipulated number, the method for network registry of the present invention also comprises:
Described first sub-district is recorded in the blacklist of forbidding registering.Wherein, described blacklist is meant forbids the sub-district list registered, after first sub-district is put on the blacklist, UE will no longer initiate registration to the sub-district that is recorded on the blacklist according to described blacklist in the described stipulated time, promptly no longer initiate registration to the base station of first sub-district.Concrete, UE is recorded in the cell identity information of first sub-district in the sub-district list of forbidding registering, optionally, cell identity information is sub-district ID (IDentity), be the ID of the base station of sub-district, in the described stipulated time, UE will can not attempt registering the sub-district of this ID of ownership.
Equally, because the mobility of UE, when the UE occurrence positions moved, the sub-district that is recorded in the blacklist may no longer be the sub-district that UE can't successfully register, and becomes the optimum subdistrict that UE can register on the contrary.
Therefore, optionally, if UE is in the described stipulated time, register described other sub-district successes, UE will remove described blacklist, after moving with effective assurance UE occurrence positions, can choose optimum subdistrict and carry out network registry, can successfully carry out network registry, improve UE and carry out the reliability of network registry and the communication quality between UE and the sub-district, promote user experience.
Optionally, in one embodiment of the invention, UE can be after the described stipulated time, remove described blacklist, so that UE can re-register the sub-district of former record in described blacklist, guarantee that UE can choose optimum subdistrict and carry out network registry, can successfully carry out network registry, improve UE and carry out the reliability of network registry and the communication quality between UE and the sub-district, promote user experience.
In addition, preferred, for current 3GPP standard compatibility, when UE shuts down or restart, UE will remove described blacklist, like this, search the restriction that net registration behavior can not be subjected to blacklist after the UE start, meet to have the 3GPP standard now.
Further describe in detail below by the method for specific embodiment network registry of the present invention.
In the method for the network registry of present embodiment, as shown in Figure 2, may further comprise the steps:
Step 201, UE selects registration first sub-district according to protocol algorithm, sends ATTACH REQUEST to the base station of first sub-district, and writes down the sub-district ID of first sub-district, starts timer T1 simultaneously.
Wherein, the timing of timer T1 is 15 seconds.If in the T1 timing, UE does not receive the response of base station of the sub-district of registration that requires, and timer T1 is overtime promptly to represent this network registry failure of UE, and UE will initiate retry (retry) and register.
According to existing 3GPP standard, in the present embodiment, the maximum retry registrations of UE 4 times.In each retry registration process, UE will select a sub-district to initiate registration according to protocol algorithm, and write down the sub-district ID of each retry registration, and restart timer T 1, if T 1 is overtime, after representing registration failure T1 the 5th time overtime, i.e. 4 all failures of retry registration, UE will enter the PLMN-SEARCH pattern.
Wherein, described protocol algorithm is the UE cell selecting algorithm of existing protocol regulation, in the present embodiment this is not done and gives unnecessary details.
Step 202, T1 is for the first time overtime, and UE enters the retry registration process, and UE will write down the frequency of failure of the base station of registration first sub-district, and this frequency of failure is that the continuous retry of UE is registered the frequency of failure of the base station of first sub-district.
Optionally, the frequency of failure of the base station of registration first sub-district of UE record can be registered the frequency of failure of the base station of first sub-district for the continuous frequency of failure or the continuous retry of UE of registering the base station of first sub-district of UE, and the frequency of failure that present embodiment is registered the base station of first sub-district with the continuous retry of UE record UE is that example describes.
In the present embodiment, suppose each retry registered UE all to the initiation registration of the base station of first sub-district, and the failure of the retry registration process of UE, promptly UE retry registers 4 all failures in base station of first sub-district.
The sub-district ID that UE is write down in the time of can registering according to each retry, the sub-district of determining each retry registration is the base station of first sub-district, simultaneously, optionally, UE can be according to the overtime number of times of timer T1, write down out continuous retry and register the frequency of failure of the base station of first sub-district, in the present embodiment, the frequency of failure that continuous retry is registered the base station of first sub-district is 4 times.
Step 203, when the frequency of failure of registering the base station of first sub-district when the continuous retry of UE reached 4 times, UE was recorded in the sub-district ID of first sub-district in the blacklist of forbidding registering, and enters the PLMN-SEARCH pattern, starts timer T0 simultaneously.
The described timer T0 time regularly is 90S,
Step 204 is when timer T0 is not overtime, under the PLMN-SEARCH pattern, UE periodically initiates to search the net registration process, according to described blacklist, UE will can not attempt the base station of first sub-district of registration on blacklist, and will select to initiate registration to other sub-districts according to protocol algorithm.
In the present embodiment, after the continuous retry of UE is registered the base station failure 4 times of first sub-district, UE is before timer T0 is not overtime, promptly in the time of 90S, will can not initiate registration to the base station of first sub-district, and select to initiate registration to the base station of other sub-districts except that the base station of first sub-district, therefore, can guarantee effectively that UE is registered to available network, has obviously promoted user experience.
Optionally, after step 204, before T0 was overtime, if the success of the network registry of UE, UE removed described blacklist; In addition, optionally, UE can also remove described blacklist after T0 is overtime.Like this, make when UE initiates network registry once more, again can be registered to the sub-district of the registration that is under an embargo in the blacklist, after guaranteeing that effectively the UE occurrence positions moves, can choose optimum subdistrict and carry out network registry, guarantee that effectively UE successfully carries out network registry, improve UE and carry out the reliability of network registry and the communication quality between UE and the sub-district, promote user experience.
In addition, optionally, when UE shut down or restart, UE also can remove described blacklist, like this, searched the restriction that net registration behavior can not be subjected to blacklist after the UE start, met existing 3GPP standard.
Corresponding with preceding method, the embodiment of the invention also provides a kind of UE, as shown in Figure 3, comprising:
Number of times record cell 10, be used to write down the frequency of failure of the base station of registering first sub-district, wherein, the frequency of failure of the base station of described registration first sub-district for the frequency of failure of the base station of registration first sub-district continuously or continuously retry register the frequency of failure of the base station of first sub-district;
Registering unit 20 reaches stipulated number if be used for the frequency of failure of number of times record cell 10 records, and registration is initiated in the base station of introversive other sub-district except that the base station of described first sub-district at the appointed time.
The UE that the embodiment of the invention provides, after UE attempts registering the base station failure of first sub-district continuously, UE will no longer initiate registration to the base station of first sub-district, and select to initiate registration to the base station of other sub-districts except that the base station of first sub-district, therefore, can guarantee effectively that UE is registered to available network, has obviously promoted user experience.And the method for this network registry of UE is not subjected to the restriction of network design, under any network design, can guarantee effectively that all UE is registered to available network, has strengthened the flexibility that network is arranged net.
Optionally, described stipulated number is not limit, and can be provided with arbitrarily, for example is 1 time, 2 times, 3 times or 4 inferior.Preferably, if during the frequency of failure of the base station that the frequency of failure of the base station of registration first sub-district of number of times record cell 10 record is continuous retry registers first sub-district, described stipulated number can be set to 4 times; Obviously, preferred, if the frequency of failure of the base station of registration first sub-district of number of times record cell 10 records be that described stipulated number can be set to 5 times when registering the frequency of failure of base station of first sub-district continuously.
Wherein, the described stipulated time can be limited duration, also can be unlimited duration, and the present invention does not do qualification to this.Because UE has mobility, when UE is moved, first sub-district that originally can't register may be changed the optimum subdistrict that current UE can be registered into before, therefore, the described stipulated time can preferably be set to limit, so that through after the described stipulated time, UE can initiate registration to the base station of first sub-district, to guarantee effectively that further UE successfully carries out the sub-district registration, guarantee that effectively UE can choose optimum subdistrict and carry out network registry, improve the reliability of enter the internet registration and the communication quality between UE and the sub-district, promote user experience.Preferable, the described stipulated time can be 60 to 120 seconds, for example is 90 seconds.
Concrete, in one embodiment of the invention, as shown in Figure 4, the UE that the embodiment of the invention provides also comprises:
