Embodiment
To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, intactly description, obviously, 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 are not paying the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
The control method flow chart of the accessing terminal to network that Fig. 1 provides for first embodiment of the invention.The executive agent of present embodiment can be core net node.As shown in Figure 1, the control method of present embodiment accessing terminal to network comprises:
When the terminal moves to a certain roaming place, can be according to the network of preset ad hoc rules search roaming place, send position updating request to the access point of a certain network that searches, carry the identity information at terminal in this position updating request.With the current access point that is connected in terminal with self information, send to core net node like the address information of access point self and the information such as identity information at terminal.
Core net node can obtain the location updating message at this terminal through the mode of record; For example: write down the number of times that position updating request is initiated at this terminal; And/or the time of record terminal initiation position updating request, and/or the access-in point information of the record current connection in terminal etc.
Core net node stores the information of cooperative network of network and the operator of operator in advance.The network that the embodiment of the invention possibly cover the roaming place is divided into: the not preferred network at the preferred network at terminal and terminal.Wherein, the preferred network at terminal comprises: the network of said terminal attaching operator, and/or, the cooperative network of said terminal attaching operator.The not preferred network at terminal comprises: cover said roaming place, the network except that said preferred network.
Core net node can confirm according to the identity information at terminal whether the access point of the current connection in terminal belongs to the preferred network at terminal.If core net node is confirmed the access point of the current connection in terminal and belonged to the preferred network at terminal, then allow the terminal to be linked into preferred network through this access point.The terminal is linked into preferred network, can guarantee the income of terminal attaching operator; Simultaneously, speech quality, low rate etc. preferably are provided, make the terminal can enjoy service preferably, help guaranteeing the consistency of user experience because preferred network is generally the user of its registration.
If core net node is confirmed the access point of the current connection in terminal and belonged to the not preferred network at terminal, then, determine whether to allow the terminal to pass through said access point according to comparative result and insert not preferred network the location updating message and pre-conditioned the comparing at terminal.If it is pre-conditioned that the location updating message at terminal satisfies, then allow the terminal to pass through said access point and insert not preferred network; Otherwise not preferred network is inserted through said access point in the refusal terminal.The terminal needs to confirm again the network that request inserts, and the position that makes repeated attempts is upgraded, and until selecting preferred network, perhaps, selects the location updating message at not preferred network and this terminal to satisfy when pre-conditioned, can insert not preferred network to enjoy communication service.
The location updating message at terminal can comprise following one or more: the number of times of position updating request is initiated at the terminal; The time of position updating request is initiated at the terminal; The information of access point.Pre-conditioned comprise following one or more: the maximum times of position updating request is initiated at the terminal; The duration of adjacent twice position updating request is initiated at the terminal; The number of times of identical access-in point information.
Initiate the number of times of position updating request for this terminal when the location updating message at the terminal that obtains; Pre-conditioned when initiating the maximum times of position updating request for this terminal; If core net node is judged this terminal and initiated the total degree of position updating request and surpass the maximum times that position updating request is initiated at the terminal, then allow the access point of terminal through current connection to insert not preferred network.
Initiate the time of position updating request for this terminal when the location updating message at the terminal that obtains; Pre-conditioned when initiating the duration of adjacent twice location updating message for the terminal; If core net node is judged the time interval that this time and last time of initiating position updating request was initiated position updating request at the terminal; Surpass the duration that adjacent twice position updating request initiated at said terminal, then allow the access point of terminal through current connection to insert not preferred network.
Location updating message when the terminal that obtains is the information of access point; Pre-conditioned when being the number of times of identical access-in point information; If core net node is judged the number of times that at least twice position updating request that the access point of the current connection in terminal belongs to not preferred network and this terminal at this terminal is selected identical access point; The number of times that surpasses said identical access-in point information then allows the access point of terminal through current connection to insert not preferred network.For example: when the number of times of identical access-in point information is 2, if the terminal this initiate the access-in point information of position updating request when identical with the access-in point information of formerly initiating position updating request, then allow the terminal to insert not preferred network.When the number of times of identical access-in point information is N, when selecting the number of times of identical access point to surpass N time when position updating request is initiated repeatedly at the terminal, then allow the terminal to insert not preferred network.
On the basis of technique scheme, if accessing terminal to network, as inserted preferred network or not preferred network, explain that then roaming terminal has successfully carried out the position renewal.Under this situation; Core net node can be removed the location updating message at this terminal that has obtained; For example: the number of times zero clearing of position updating request is initiated at this terminal that will write down, and/or, empty the time that position updating request is initiated at this terminal of having write down; And/or, empty the access-in point information in position updating process, selecting to connect in this terminal of having write down etc.
In the control method of present embodiment accessing terminal to network; With roaming terminal initiate the position more the network type that inserts of new technological process time request and the location updating message at terminal take into consideration, the location updating message that belongs to not preferred network and terminal at the access point of the current connection of roaming terminal satisfies when pre-conditioned, allows the terminal to insert not preferred network; Therefore; When preferred network does not cover the roaming place, can guarantee that the terminal inserts not preferred network, to satisfy the communication requirement at terminal.
The control method flow chart of the accessing terminal to network that Fig. 2 provides for second embodiment of the invention.In the present embodiment application scenarios, the location updating message at the same terminal of core net node record is: the number of times of position updating request is initiated at the terminal; Pre-conditionedly be: the maximum times of position updating request is initiated at the terminal.As shown in Figure 2, the control method of present embodiment accessing terminal to network comprises:
Position updating request is sent to the access point from a certain network that searches in the roaming place in step 21, terminal, comprises the identity information at terminal in the position updating request.
Step 22, access point send the identity information at access-in point information and terminal to core net node.The identity information send mode at access-in point information and terminal is unrestricted, optional, and the identity information at access-in point information and terminal is carried in to upgrade in the position requests and sends to core net node.
The total degree that position updating request is initiated at step 23, core net node record terminal, as: the number of times that position updating request is initiated at this terminal that core net node has write down self adds 1.
Step 24, core net node judge according to the identity information at access-in point information and terminal whether access point belongs to the preferred network at terminal, if access point belongs to the preferred network at terminal, and execution in step 25; If access point does not belong to the preferred network at terminal, promptly access point belongs to the not preferred network at terminal, execution in step 26.
Step 25, core net node allow the access point access preferred network of terminal through current connection, and the total degree zero clearing of this updating of terminal position that will write down; Process ends.
Whether step 26, core net node judge the total degree of initiating position updating request in the terminal above maximum times, if the total degree that the terminal initiates to upgrade the position surpasses maximum times, execution in step 27; Otherwise, execution in step 28.
Core net node can be provided with maximum times according to actual needs, and concrete implementation is unrestricted.Optional, can like the roaming place network 3 operators be arranged according to the quantity setting of regional operator, then can maximum times be preset as 3 times.The benefit of so handling is: because terminal search and when confirming network that request inserts in the roaming place, the network of the request access that possibly at first confirm is not the preferred network at terminal just; Maximum times is set to the total quantity of operator, so that each network that the terminal possibly search carries out the poll position updating request one time, to improve the probability that preferred network is inserted at the terminal.
Step 27, core net node allow the terminal to insert not preferred network through this access point, and the total degree zero clearing of this updating of terminal position that will write down; Process ends.
Not preferred network is inserted through this access point in step 28, core net node refusal terminal; If more new technological process of position is initiated at the terminal once more, then execution in step 21.
In the control method of present embodiment accessing terminal to network; With roaming terminal initiate the position more new technological process time request network type that inserts and the number of times that the position renewal is initiated at the terminal take into consideration; If the network that the terminal is selected to insert is a preferred network, then allow the terminal to insert; If the network that the terminal is selected to insert is not preferred network, when the number of times of initiation position updating request surpasses maximum times at the terminal, allow the terminal to insert not preferred network.The benefit of so handling is:
Because during the network that the terminal is searched in the roaming place and definite request inserts; The network that the request that possibly at first confirm inserts is not the preferred network at terminal just; Under this situation; When the number of times of core net node initiation position updating request at the terminal surpassed maximum times, not preferred network was inserted at the refusal terminal, thereby helped improving the probability that preferred network is inserted at the terminal.Further; Even the preferred network at terminal does not cover the roaming place, when the number of times of core net node initiation position updating request at the terminal surpasses maximum times, allow the terminal to insert not preferred network; Satisfying the communication requirement at terminal, thereby guarantee the reliability of roaming terminal access network.

Position updating request is sent to the access point from a certain network that searches in the roaming place in step 31, terminal, comprises the identity information at terminal in the position updating request.
The time that position updating request is initiated at step 33, core net node record terminal, computing terminal is initiated the time interval of adjacent twice position updating request.
Step 34, core net node judge according to the identity information at access-in point information and terminal whether access point belongs to the preferred network at terminal, if access point belongs to the preferred network at terminal, and execution in step 35; If access point does not belong to the preferred network at terminal, promptly access point belongs to the not preferred network at terminal, execution in step 36.
Core net node can be provided with preset duration according to actual needs, and concrete implementation is unrestricted.Optional, after can presetting duration and being set to network that the terminal traversal once searches, in the time of still can't access network, the required time interval of traversal of initiating a new round.Usually, if behind the network that the terminal traversal once searches, the position is upgraded when still failing, and can attempt the request of a new round.In the time interval between the two-wheeled request, longer, optional with respect to the time interval between heterogeneous networks in same the wheel, core net node can be preset duration and be set to the required duration of terminal initiation two-wheeled position updating request.
Not preferred network is inserted through this access point in step 38, core net node refusal terminal; If more new technological process of position is initiated at the terminal once more, then execution in step 31.
The control method of present embodiment accessing terminal to network; Take roaming terminal into consideration and initiate the acquisition time interval of the position network type that more request the inserts during new technological process location updating message adjacent twice with this terminal; If the network that the terminal is selected to insert is a preferred network, then allow the terminal to insert; If the network that the terminal is selected to insert is not preferred network, the time interval of initiating adjacent twice position updating request at the terminal surpasses when presetting duration, allows the terminal to insert not preferred network.The benefit of so handling is:
Owing to during the network that the terminal is searched in the roaming place and definite request inserts, let the terminal attempt one as far as possible and take turns the heterogeneous networks that the roaming place searches, thereby help improving the probability of terminal access preferred network.Further; If preferred network does not cover the roaming place, when the time interval that core net node obtains twice location updating message surpasses preset duration, allow the terminal to insert not preferred network; Satisfying the communication requirement at terminal, thereby guarantee the reliability of roaming terminal access network.
