Peripheral service area when the 1st base station 20 at mobile communication terminal 10 places is contained in the coverage of N base station 25, and the signal quality of N base station 25 is when good, mobile communication terminal 10 inserts N base station 25, registration location in N mobile switching centre 35, thus continue to obtain the mobile communication service by roaming.
When the N net of above-mentioned mobile communication terminal 10 access N base stations 25 and N mobile switching centre 35 and registration, mobile communication terminal 10 needs retrieval N net, when above-mentioned steps retrieves the N net, should select N base station and request to insert registration location under the state that inserts according to request.
As above near the retrieval network and insert, registration, this can be because of frequency environment difference to some extent, but the problem that exists is to need 5 seconds to 40 second time at least.
Also there are the following problems in addition, when utilizing the network retrieval catalogue in above-mentioned network retrieval process, make to insert other network to register, all need the time same as described above, before above-mentioned registration was finished, above-mentioned mobile communication terminal 10 can't obtain communication service at every turn.
With reference to the accompanying drawings 2, the manual network cut-in method of mobile communication terminal under the conventional art is described.
When to utilize above-mentioned mobile communication terminal 10 manually insert near during other communication network (as step S10), retrieval nearby receives all communication networks of signal, is made into catalogue (as step S20).
In above-mentioned steps S20, receiving the communication network of signal near the retrieval and be made into required time of catalogue can be because of electric wave environment on every side difference to some extent, at least need 5 to 40 seconds (being benchmark with U8110), before search complete, mobile communication terminal was in the state that can't carry out other function until above-mentioned.
The catalogue of as above finishing retrieval and making is in certifiable state by the corresponding display part output of mobile communication terminal.
The catalogue that MS manual search as above shows, manually selection hobby or the communication network (as step S30) that needs are to the network connection requests (as step S40) of corresponding base station wireless transmission and above-mentioned selection.When the connection request according to above-mentioned steps S40 connected, the position in that mobile communication terminal is registered by the mobile switching centre (MSC) of the network that inserts obtained mobile communication service (as step S50) by roaming.
The network that wireless access is selected until required time of registration can because of around electric wave environment difference to some extent, need 5 seconds to 40 second time.When finishing when registration, receive and the registration that the shows mobile switching centre message that finishes, thereby learn the state that can obtain the mobile communication service that is in by roaming.
When the service quality of the mobile radio communication of registering by above-mentioned MS manual search and selection descends, can insert other mobile radio communication of from the network directory of original retrieval, manually selecting, even under as above situation, still need 5 seconds to 40 seconds time, have the register step complexity, finish the problem that to waste the plenty of time before to registration.

In addition, in following explanation, such as many specific details such as concrete handling processes, provide for a more complete understanding of the present invention, do not have these specific details, the present invention also can implement, and this is self-explantory the commonsense people of this technical field.And, omitted thinking the well-known function that may unnecessarily obscure main idea of the present invention and the detailed description of formation.
Under situation in the past, when this network directory had been stored in the terminal inner database, may not needing home, area retrieval mobile radio communication (network) also generated the step that can insert catalogue.
Therefore, in the present invention, under the situation of not searching the required other search operation of above-mentioned network directory, directly show the tabulation of storage, thereby have the effect that can make the user select the network of needs to insert quickly.That is, when the user when operation on MMI (Man Machine Interface, the man-machine interface) menu is manually selected network, directly demonstrate the network list of storage, make the user can insert required network rapidly.
As to the replying of above-mentioned manual network select command, shown network list is constructed as follows.
At first, (for example: SKT distinguish different network, LGT, KTF) network ID (PLMN ID) constitutes by amounting to 5 numerals, and in these 5 numerals, three is country code (MCC:mobile country code, mobile country code), 2 is mobile network code (MMC:mobile network code), and in a country, the network number with identical MCC limits.
Shown in above-mentioned example, 3 networks with identical MCC are arranged at home, and (for example: SKT, LGT KTF), waits other country in Europe, also is to have a plurality of networks according to the situation of country separately.Therefore, in the present invention, imported user's manual network select command after, need not actual execution web search step, but from database, search the all-network that has with the identical MCC of network that inserts now, directly be shown as the tabulation form and get final product.
Because for mode as above, in original mode, physical layer is actual carries out that network list that web search obtained is often lacked than the network list of storing in the database or equal.That is, in the present invention, the network list of storing in the database has comprised the all-network tabulation of being retrieved by the real network search, has the advantage that can widen user's range of choice on the contrary.But, at this moment the problem that may occur is, when as above manually selecting network in country indirect territory district, in fact, if carry out web search in physical layer, then the network signal of two countries all can searchedly arrive, and has therefore lost only finding the guarantee with identical MCC network.That is, different when searching for when only showing network list with real network with MCC identical with the network that inserts now, the network that may occur being left out.Therefore, in the present invention,, added the submenu of carrying out real network search and output network tabulation as the countermeasure of as above selecting in the manual network of multinational contiguous areas.When only conversing at home, select by manual network, rapidly access network; In multinational contiguous areas, because the user knows it is the contiguous areas here, so by submenu or change pattern, the retrieval all-network generates network directory.
Fig. 3 is the precedence diagram of the communication network variation of mobile communication terminal of the present invention, in the time will inserting other communication network use roaming service from the mobile radio communication change of present access, input manual network select command, the network directory of the established condition of storing in advance in the output database, the network of selecting in this network directory to the user (mobile radio communication) inserts registration.That is, terminal inserts control request signal to the Network Transmission of above-mentioned selection, judges whether to insert the mobile radio communication that above-mentioned request inserts, if insert, then circulates a notice of the positional information of mobile communication terminal to the communication network of above-mentioned access, carries out location registers.
That is to say that when above-mentioned mobile communication terminal will insert other adjacent mobile radio communication for the service quality of the network that improves present access, the network directory of storing in the searching database was selected the network that needs in above-mentioned catalogue.
Therefore, compared with the past, have the effect that can save retrieval network, make the time of catalogue.Whether retrieval exists the identical network of above-mentioned selection, inserts corresponding base station, and the present position information of circular terminal after registration is finished, is called out connection by the network of change.
On the other hand, the area that has the MCC heterogeneous networks in for example area, border etc., in the time will changing network (roaming service), submenu or mode altering menu by terminal provides to the protocol stack transferring command (web search order) of terminal, carry out the web search operation in the physical layer of terminal, generate the real network catalogue at this moment, in network directory, be not only identical MCC, the network with different MCC also can be retrieved.
So, behind the network that the user selects to need in above-mentioned network directory, by with the above-mentioned identical step of manual selection network in area home, carry out finishing change to the network site registration of selecting.That is, in mode in the past, be directly to assign user's manual network select command to the software protocol storehouse of terminal inner, required time is equivalent to reality and carries out the required time of web search in physical layer.But in the present invention, directly do not assign user's manual network select command to protocol stack, but qualified network (network) in the network that the direct video data of application program storehouse is stored with identical MCC, can shorten the web search required time, the realization fast network inserts, carry out the real network search in the area, border that has other national network, thereby can stably change access network.
