Background technology
Along with the development of 3G technology, increasing terminal is supported 2G and 3G simultaneously, and the terminal that is supported in seamless switching between 2G and the 3G is also more and more.Simultaneously, the networking of operator is also uneven.The 2G network coverage of some Incumbents is more complete, and the 3G network covering may be fewer, therefore in self infull zone of 3G network covering, just need rent the 3G network of other operator.And some emerging operators can directly begin to lay 3G network, and do not lay the 2G network, do not have the place that covers at self network like this, also need to rent the network of other operator.Even the virtual operator that has do not lay network, and directly rents the network of other operator.These several situations are very general at present.
When the carrier network covering is incomplete, need to increase user's experience on the one hand, allow the user not fall net as far as possible, when having 3G to cover, preferentially use the network of 3G.On the other hand, also need to reduce the wandering fee of operator self, become the problem that needs solve.
Prior art solutions is as follows: in terminal registration network, can be at first the Public Land Mobile Network successfully registered last time of registered user (Re-Public Land Mobile Network, RPLMN).(Public Land Mobile Network PLMN) has two kinds of access technologies, is respectively 2G and 3G because with a kind of Public Land Mobile Network.If it is preferential that terminal is arranged to 3G, will at first search for 3G, if do not search the RPLMN of 3G network, will search for the RPLMN of 2G network once more.If the PLMN of these two kinds of access technologies does not search or registration failure, terminal can be according to the following PLMN order renewal of registration, successful up to registered network: the Public Land Mobile Network of ownership (HomePublic Land Mobile Network, HPLMN), Subscriber Identity Module (Subscriber IdentityModule, SIM) PLMN of user-controlled PLMN and operator control in, the PLMN of the high signal quality of random alignment, and the PLMN of other signal quality descendings.In these PLMN of search registration, also be preferential, register the network of corresponding access technology respectively according to terminal default 2G or 3G.As long as the PLMN of any one access technology is registered success, just can not register the low network of ensuing priority again.
In research and practice process to prior art, the present inventor finds that existing register method is unfavorable for the roaming between the operator; Registration order is uncontrollable; May cause user experience poor.
Embodiment
The embodiment of the invention provides a kind of communication network registry method, and the embodiment of the invention also provides the corresponding mobile terminal.Below be elaborated respectively.
Embodiment one, see also Fig. 1, this figure is the schematic diagram of an embodiment of a kind of communication network registry method of the present invention;
Step 101, terminal are safeguarded standard list;
Terminal is safeguarded the standard list of a preferential PLMN/ access technology of selecting.Each element comprises the PLMN of network in the described standard list, and access technology.Described standard list can safeguard by several different methods, for example writes on terminal the inside (for example non-volatile internal memory in the terminal) by operator, or the user can revise or the like, include, but are not limited to that top these are several.This tabulation also is the PLMN/ access technology sequential list that terminal is preferably registered, and is called tabulation A.For example: the 2G network coverage of the A of operator is very complete, and is complete inadequately but 3G network covers, and the covering of the 3G network of the B of operator is fine, so the A of operator has rented the 3G network of the B of operator.The PLMN of the A of operator is PLMNA, and the PLMN of the B of operator is PLMNB.The A of operator requires as follows: the 3G signal area of A and B is arranged at the same time, and terminal preferentially inserts the 3G network of A; Have at the same time under the situation of 3G of the 2G of A and B, terminal preferentially inserts the 3G network of B; In the 2G signal overlap zone of 2G and the B of A, terminal preferentially inserts the 2G network of A.The order that therefore can write preferred PLMN/ access technology tabulation in terminal is: PLMN A 3G, PLMN B 3G, PLMN A 2G, PLMNB 2G (priority is arranged from high in the end).
Further can increase step: terminal is read RPLMN from SIM card, HPLMN, and user-controlled PLMN/access technology, and the PLMN/ access technology of operator's control.The priority of these PLMN/ access technologies will be lower than the priority among the tabulation A, also joins among the tabulation A.
Step 102, terminal searching network, and classify the network that searches as a tabulation;
Behind the mobile terminal-opening, perhaps at no service area, at first carry out full frequency band and search net, the frequency range of supporting according to terminal, the access technology of being supported, the search all-network generates a tabulation, each element all comprises the PLMN and the access technology of network in this tabulation, the current available PLMN/ access technology tabulation B of the conduct of this PLMN/ access technology.
Step 103, terminal registration network;
Seek successively among the B in tabulation registered network is registered, described the priority of registered network in tabulation A should be higher than the priority of other all-networks in tabulation A among the tabulation B.Just the network of last registration should be the successful the highest network of priority that exist in this zone and registrable, and the height of priority is judged according to tabulation A.When selected network registration is unsuccessful, from tabulation B, select next network to register in time high PLMN/ access technology of tabulation A medium priority.
In the embodiment of the invention, employing is sorted available network according to priority in a tabulation, behind all registrable networks of terminal searching, in the described registrable network that searches, seek and register, can guarantee endpoint registration best network of service in the current available network like this according to the highest network of described list ordering.
When the network of endpoint registration is not the network of limit priority among the tabulation A, can further adopt following steps:
Step 104, starting terminal timer;
At any time, on the endpoint registration after the network, if the PLMN/ access technology of this network is not a limit priority in tabulation A, then start a timer, the time length of this timer can be controlled in SIM card by operator, also can control, perhaps write in the non-volatile internal memory of terminal by the user.Certainly include, but are not limited to top situation.
Step 105, timer are crossed after date terminal search network once more;
After timer was expired, terminal was carried out the search of BPLMN.The search of BPLMN is the search on the backstage, can not influence user's experience, and terminal still can obtain to serve normally in search network.Only search for those PLMN/ access technologies higher in tabulation A herein during search network than the PLMN/ access technology priority of current registration.If the tabulation B non-NULL of search, in tabulation B the inside, A judges priority according to tabulation so, successively the wherein registrable the highest network of priority of registration.Therefore the network in the last registration should be the highest network of priority that exists in this zone, and the height of priority is judged according to tabulation A.Promptly get back to step 102, just the hunting zone is littler.When the network of registration is not in the tabulation during limit priority, utilize timer function in the step of increase, therefore search once more as long as the high network of priority all can more preferably be registered, helps the roaming between the operator behind certain interval of time.
If the result of search is empty, the network of perhaps last registration neither be tabulated the highest in the A medium priority.Repeating step 104-step 105 so.
The embodiment of the invention adopts the recording user available network, and according to priority is arranged as tabulation; In the energy registered network that searches, search the highest network of tabulation medium priority and register,, help the roaming between the operator owing to, preferentially register the high network of priority that searches according to the priority orders that is ranked in advance; Registration order can be controlled; The user can be registered to the network of limit priority, obtains better service experience.
