Abstract
The invention provides a method and a terminal for residing a network. When the terminal needs to perform business, a network which can support the terminal's business to be performed is chosen to perform the business, so that when the terminal is standby and the networks that perform the terminal's business are different, for each time the terminal performs the business, system overhead of returning to the network in which the terminal is standby is reduced at least once. When the terminal needs to use the different networks from the network in which the terminal is standby for a plurality of times, the returning overhead is reduced, meanwhile, the overhead of accessing to the network for performing the business from the network in which the terminal is standby is also possibly reduced. Therefore, frequency of interoperate among the networks is greatly reduced, load of the networks is reduced, and reduction of paging call completing rate of a user caused by frequent intersystem re-selection is prevented.
Description
Technical field
The present invention relates to communication technical field, particularly relate to a kind of method and terminal of network resident.
Background technology
Along with developing rapidly of the communication technology, the legacy network such as GSM network, TD-SCDMA network is ripe gradually, and in order to promote network communications capability, create again various new network, as LTE network, various types of network (comprising legacy network and various new network) is present in communication system simultaneously, therefore, in a communications system, terminal selects the network of which kind of type to carry out communicating and become the problem that is needed badly solution.
For this problem, point out in standard agreement, can be various dissimilar network settings priority, priority level is divided into 0 ~ 7 totally eight grades from low to high, and issues network priority configuration information by broadcast, and terminal is after listening to broadcast, can according to the priority of network, and the network that neighbouring community is supported, preferentially resident in the community that high-priority network is corresponding, thus realize resident at high-priority network.
In the prior art, be generally the priority that the stronger network settings of communication capacity are higher, make terminal preferentially resident in the network that communication capacity is strong.But, usually it is not yet ripe to there is partial service in the construction period in some network (new network of construction as new in some), cover not congruent defect, need by with other internetwork interoperability behaviors, fully could ensure the business continuance of terminal and the seamless coverage communicated, therefore terminal usually can covering Network Based or business demand, utilize circuit domain dropping (CSFB, Circuit SwitchedFall Back) technology, by falling after rise (as gravity treatment, switch) the more weak network resident of mode access communications ability or the business of execution, after the network coverage that standby service terminates or communication capacity is stronger recovers, terminal is by according to the precedence information issued in broadcast, be back to the network resident of high priority.
Or, also can be the priority that condition carrys out setting network according to network coverage, network design integrity, for network coverage is wider, priority that network design is more perfect network settings are higher, make in the terminal network that preferentially, network design wide at network coverage is perfect resident.But, some network (as some legacy network) due to communication capacity limited, also need by with other internetwork interoperability behaviors, fully could ensure the business of terminal, as the normal execution of video call service.Therefore terminal usually can based on business demand; by falling after rise, mode access network coverage is narrower, the relatively incomplete network of network design performs business; after standby service terminates, terminal, by according to the precedence information issued in broadcast, is back to the network resident of high priority.
Be illustrated in figure 1 in prior art, carry out the schematic diagram of network resident, suppose to there is LTE network in communication system simultaneously, TD-SCDMA network and GSM network, according to the rule of the higher priority of the network settings that communication capacity is stronger, if priority from low to high respectively by 0 ~ 7 totally 8 grades represent, the priority that then can set LTE network is 7, the priority of TD-SCDMA network is 3, and the priority of GSM network is 0, then the flow process that in prior art, terminal carries out network resident specifically comprises:
After powering, the network can supported according to self, searches for each community, measures for the first step, terminal, and in the network selecting self to support, the community that the network of signal quality the best is corresponding is accessed, thus the network of access signal quality the best.
In this step, if terminal supports LTE network, GSM network and TD-SCDMA network simultaneously, then terminal after powering, selects the network insertion of signal quality the best in LTE network, GSM network and TD-SCDMA network, such as, access LTE network.
Second step, terminal monitoring cell broadcast messages, according to the priority configuration information in broadcast, initiate the measurement to highest priority network.
In communication system as shown in Figure 1, the priority of each network is followed successively by LTE network, TD-SCDMA network and GSM network from high to low, in this step, terminal will attempt the highest LTE network of access priority, thus realizes standby in the network that priority is the highest.
If terminal is GSM network in a first step, then in this step, first terminal can initiate the measurement to LTE network, and the LTE network accessing to limit priority after LTE signal strength signal intensity meets certain condition is resident.
If find that LTE signal strength signal intensity can not meet access conditions to the measurement result of LTE network, then terminal continues to measure TD-SCDMA network, when TD-SCDMA signal strength signal intensity meets access conditions, terminal first will access TD-SCDMA network, and constantly initiates the measurement to LTE network.
If what terminal accessed in a first step is TD-SCDMA network, then in this step, terminal can initiate the measurement to LTE network, and the LTE network accessing to limit priority after LTE signal strength signal intensity meets certain condition is resident.
If terminal accesses LTE network in a first step, then there is not the network higher than LTE network priority in cell broadcast messages, so terminal can not be initiated to measure to other networks, but always resident in the lte networks.
3rd step, terminal perform business.
Suppose that, in previous step, terminal resides in LTE network, then terminal is once there be data traffic requirement, can obtain the high-speed transfer service that LTE network provides the very first time, and after business is finished, continues to reside in LTE network.
And terminal is once there be voice traffic needs, because current LTE network technology is not yet ripe, cannot direct voice-over business, as shown in Fig. 12,4, terminal will fall after rise to TD-SCDMA network or GSM network by LTE network, voice service is performed in TD-SCDMA network or GSM network, and after business is finished, as shown in Fig. 11,3, again LTE network is measured, when LTE signal strength signal intensity meets certain condition, return to LTE network resident.
It should be noted that, in second step and the 3rd step, terminal is in the resident process of LTE network, once terminal leaves the LTE network area of coverage, namely when current LTE signal quality is lower than a certain thresholding, as shown in Fig. 12,4, terminal can initiate the measurement to other low priority networks, and falling accesses to community corresponding to low priority network.But once again monitor the LTE network of limit priority, as shown in Fig. 11,3, terminal can initiate again the measurement to LTE network, when meeting LTE signal strength signal intensity and meeting access conditions, return LTE network, thus realize the object residing in the LTE network of high priority as far as possible.
Equally, if terminal accesses GSM network after leaving LTE network, again return the process of LTE network from GSM network in terminal, if LTE signal strength signal intensity can not meet access conditions, but TD-SCDMA signal strength signal intensity meets access conditions, then terminal first will access TD-SCDMA network, and constantly initiates the measurement to LTE network.
In above-mentioned prior art, the scheme Problems existing of terminal processes different network interoperability is:
The scheme of the first step ~ the 3rd step can be found out, terminal extremely performs in the process of business from start, if the network at place is different network when the network selected during starting up of terminal and terminal standby, and during terminal standby, network and the terminal at place performs the network of business when being also different networks, terminal at least will perform three network round-trip, the business that especially cannot perform at high-priority network be need often to perform core business (as, the voice service that LTE network cannot perform), and cover the border district signal fashion of the high-priority network (time bad) at high-priority network, all will terminal be caused constantly to travel to and fro between different networks, carry out network falling continually, the operations such as measurement and gravity treatment, make the frequency of interoperability between heterogeneous networks high, produce a large amount of signaling consumptions, emphasis network is born, waste Internet resources, simultaneously, when performing network (community) gravity treatment, for network, terminal is in unreachable state, namely terminal can not be paged, and the terminal of existing scheme needs multiple exercise network (community) reselection operation, therefore also can affect paging call completing rate largely, reduce network service quality.
And be that the priority that condition carrys out setting network exists the problems referred to above too according to network coverage, network design integrity, and there occurs change due to imposing a condition of network priority, the priority of each network also must change, therefore, the service propelling mechanism of network side also needs corresponding change occurs, and new service propelling mechanism is adapted to network side transformation, the difficulty implemented is larger, and the stability of network also can be affected on the transformation of network side, the business affecting terminal performs.
Summary of the invention
The embodiment of the present invention provides a kind of method and terminal of network resident, thus the interoperability frequency solved in prior art between network is high, causes the burden of network large, and the problem that paging call completing rate is low.
A method for network resident, the method comprises:
Reside in the terminal judges first network business whether support terminal is pending of first network;

Embodiment
In order to solve in prior art, because terminal is constantly travelled to and fro between different networks, carry out network falling continually, the operations such as measurement and gravity treatment, interoperability frequency between the network caused is high, cause the burden of network large, and the problem that paging call completing rate is low, the scheme that the embodiment of the present invention provides is from terminal, end side is transformed, utilize terminal realize provided by the invention terminal idle state (during terminal standby) and execution business time network access, resident, reduce the number of times that terminal travels to and fro between different networks, thus the interoperability frequency between reduction network, solve the technical problem that the present invention proposes.Meanwhile, terminal is carried out transforming the difficulty implemented less, realize fairly simple, and the stability of network can not be affected.
Below by each embodiment and accompanying drawing, technical solution of the present invention is described in detail.
Embodiment one,
The embodiment of the present invention one provides a kind of method of network resident, and the steps flow chart of the method as shown in Figure 2, specifically comprises the following steps:
Step 101, the terminal judges first network business that support terminal is pending.
Network priority configuration information for described pending business refers to, for pending business, supports in the network of described pending business, to the magnitude relationship of the tenability of described pending business.
In this step, reside in the terminal of first network when needs execution business, judge whether the network at self place supports the business that self is pending, specifically comprise: judge whether the priority of first network to described pending business reaches setting priority, if do not reach, then determine the first network business that support terminal is not pending, continue to perform step 102, otherwise determine the business that first network support terminal is pending, in first network, perform described pending business.
For described pending business in the network that described setting priority can be able to access for terminal, prioritization is at the network of front M position, and M is positive integer.As, setting M=3, according to the network priority configuration information for described pending business, then can judge that whether first network is in the terminal network that can access, for pending business, prioritization is at the network of first 3: if not, then continue to perform step 102, if so, then in first network, described pending business is performed.
Step 102, terminal determine the second network performing pending business.
This step specifically comprises: terminal is according to the network priority configuration information for described pending business stored, in the network that terminal can access, determine the network reaching setting priority for described pending service priority, and in the network determined, select a network as second network.
Determine the network reaching setting priority for described pending service priority, can for determining for the network of described pending service priority sequence in front M position, as, setting M=3, then can select for pending business, prioritization at the network of first 3, and from 3 networks determined, select a network as second network, for performing described pending business.
Step 103, terminal access and continue in the second network resident.
Terminal access in the second network, and after the described pending business that is finished in the second network, continue to reside in second network, and without the need to as prior art, again the network (network of high priority) accessing terminal resident when standby, thus reduce terminal number of times round between network, reduce interoperability frequency between network.
Preferably, in order to reduce the number of times that terminal comes and goes between network further, if described first network is network resident first after starting up of terminal, then terminal be positioned at the coverage of first network and terminal before access second network, terminal continues to reside in first network, and without the need to as prior art, the network of network insertion high priority resident first after start, thus interoperability frequency between network can be reduced further.
Terminal is finished after described pending business in the second network, when the signal strength signal intensity of second network does not reach setting intensity, terminal can from the network that can access, determine a network, and continue to reside in this network, to support that this terminal is as the smooth execution of the business (as called business) of passive side.
When the business that terminal is pending comprises multinomial business, for described multinomial traffic set priority, prioritizing selection network performs the highest business of the business medium priority that is not yet finished, repeat the following step, until all business are finished, reside in the network at terminal place when last business is finished:
Needing to select in the multiple business (business be not yet finished) performed the highest business of priority as the pending business of terminal, for the business that this is pending, determine second network;
After determining the second network for performing described pending business (needing the business that multiple business medium priorities of execution are the highest), determine needing in the business except business the highest except priority in the multiple business performed, the business that can perform in the second network determined;
Except the business that priority is the highest, utilize second network to perform the business that can perform in the second network determined simultaneously.
Due to the reason such as continuous movement of terminal, terminal is not in the same time, and the network that can access may be change, and namely terminal is not in the same time, may in the coverage of heterogeneous networks.In order to ensure the smooth execution of terminal traffic, terminal is after access second network, and before the described pending business that is finished in the second network, terminal repeats following process, till terminal is finished described pending business, and terminal resides in the network at place when being finished described business:
Whether terminal judges is in the coverage of second network, if so, then continues to perform described pending business in the second network; Otherwise, terminal redefine from the network that can access can the network of the pending business of support terminal as second network, and continue to perform described pending business.
Such as, terminal performs in the process of data service (pending business) in LTE network (second network), can constantly judge whether to be in the coverage of LTE network, if, then continue to perform described data service in the lte networks, otherwise, if in the T1 moment, determine not to be in the coverage of LTE network, redefine the network that terminal can access from the T1 moment can the network of supported data business as second network, if the network that T1 moment terminal can access is TD-SCDMA network and GSM network, then can redefine TD-SCDMA network (or GSM network) as second network, and continue to perform described data service in the TD-SCDMA network redefined (second network redefined).And, terminal continues to perform in the process of described data service in the TD-SCDMA network redefined, also can constantly judge whether to be in the coverage of TD-SCDMA network, if determine not to be in the coverage of TD-SCDMA network in the T2 moment, redefine the network that then terminal can access from the T2 moment can the network of supported data business as second network, and constantly whether duplicate detection is in the coverage of the second network redefined out, until data service is finished, reside in the network at place when being finished described data service.
In order to for pending business, can keep utilizing the highest network of priority to perform this pending business as far as possible, thus guarantee the implementation quality of this pending business, when performing the highest network of the priority of described pending business in the terminal network that can access at described second network, terminal is after access second network, and before the described pending business that is finished in the second network, terminal repeats following process, till terminal is finished described pending business, and terminal resides in the network at place when being finished described business:
Whether terminal detects the current network that can access and changes, when determining to occur other networks in the current network that can access, continued to perform described pending business as second network by other networks, other networks described perform the highest network of the priority of described business in the current network that can access.
Such as, the network that can access in the terminal T1 moment only has GSM network, for data service, terminal will determine that GSM network is the network that priority is the highest, terminal performs in the process of data service in gsm networks, the current network that can access can be detected whether change, if detect that the network that can access is TD-SCDMA network and GSM network in the T2 moment, then terminal will access TD-SCDMA network, TD-SCDMA network is utilized to perform data service, perform in TD-SCDMA network in the process of data service, terminal still constantly can initiate the detection to the current network that can access, if detect that the network that can access is LTE network in the T3 moment, TD-SCDMA network and GSM network, then terminal will access LTE network, LTE network is utilized to perform data service.Certainly, perform in the process of data service in LTE network, also the detection to the current network that can access can constantly be initiated, once have for data service, priority is higher than other networks of LTE network, other networks will be utilized to perform data service, and till data service is finished, terminal resides in the network at place when being finished data service.
In the method that the embodiment of the present invention one provides, network side can be transmitted control message to terminal by air interface, this control message be used for control terminal whether select the embodiment of the present invention one to provide method to realize network resident, terminal, when determining that the method that the embodiment of the present invention one can be selected to provide realizes network resident according to this control message, performs the method for the network resident that the embodiment of the present invention one provides.
Be described in detail below by two the concrete schemes of example to the embodiment of the present invention one.Suppose to there is LTE network in communication system simultaneously, TD-SCDMA network and GSM network, respectively by embodiment two, are a business with pending business, with embodiment three, be that the scheme of multiple business to the embodiment of the present invention one is described in detail with pending business.
Embodiment two,
The embodiment of the present invention two provides a kind of method of network resident, then the steps flow chart of the method as shown in Figure 3, specifically comprises the following steps:
Access network after step 201, starting up of terminal is also resident.
Terminal after powering, according to the network schemer that self supports, is searched for each network, is measured, and selects community corresponding to the network of signal quality the best to access this network.Behind access community, terminal monitoring also reads broadcast, determines the neighboring BS information of this community.But even if network corresponding to community, the terminal place network that not to be the priority that defines in standard agreement the highest, terminal also resides in this network by continuing, and without the need to accessing the highest network of the priority that defines in standard agreement.
Suppose in this step, terminal accesses and resides in GSM network.
Step 202, the terminal judges GSM network business that support terminal is pending.
In the present embodiment, will judge the priority of first network to described pending business whether reach setting priority condition be set as: judge whether the priority of first network to described pending business reaches the highest, and respectively for pending business for voice service and data service are described.
In the present embodiment and the following examples four, all set: the network priority configuration information for data service is that LTE network is higher than TD-SCDMA network, and TD-SCDMA network is higher than GSM network, namely in current communication system, to the tenability of data service putting in order as LTE network, TD-SCDMA network, GSM network from high to low.Network priority configuration information for voice service be GSM network higher than TD-SCDMA network, namely in current communication system, to the tenability of voice service putting in order as GSM network, TD-SCDMA network from high to low.
Suppose in this step, the pending business of terminal is data service:
According to the network priority configuration information for data service stored, judge whether GSM network meets predetermined condition.Because GSM network is not (comprise GSM network in the terminal network that can access, TD-SCDMA network and LTE network), for data service, (network is not for data service in the terminal network that can access for network that priority is the highest, prioritization is at the network of first 1), that is, GSM network meets predetermined condition, continues to perform step 203.
Again, suppose in this step, the pending business of terminal is voice service:
According to the network priority configuration information for voice service stored, judge whether GSM network meets predetermined condition.Because GSM network is in the terminal network that can access (comprising GSM network and TD-SCDMA network), for voice service, the network that priority is the highest, namely, GSM network does not meet predetermined condition, then, perform voice service in GSM network, and when voice service is finished, continue to reside in GSM network.
Concrete, terminal is in the support voice service determined and in the terminal network that can access, the GSM network that priority is the highest performs in the process of voice service, due to the reason such as movement of terminal, if when the signal strength signal intensity of GSM network does not reach setting intensity, access TD-SCDMA network continues to perform voice service by terminal, terminal continues in TD-SCDMA network to perform in the process of voice service, constantly can detect and whether can access GSM network, and when GSM network can be accessed, again access GSM network to continue to perform voice service, and reside in voice service when being finished, the TD-SCDMA network at terminal place or GSM network.
Terminal is after voice service is finished, to reside in when voice service is finished in the TD-SCDMA network at terminal place or the process of GSM network, if when the signal strength signal intensity of TD-SCDMA network or GSM network does not reach setting intensity, in order to ensure terminal as passive side business (as, called business) smooth execution, terminal can from the LTE network that can access and GSM network (or TD-SCDMA network), according to the definition of standard agreement, determine the network that priority satisfies condition, if condition is that priority is the highest, then LTE network can be defined as, and continue to reside in this network.
Step 203, terminal determine the network performing data service.
Terminal, according to the network priority configuration information for data service stored, determines the GSM network that terminal can access, and in TD-SCDMA network and LTE network, for data service, it is LTE network that priority meets the highest network of priority.
Step 204, terminal access and continue in the lte networks resident.
The LTE network of terminal access for performing data service, after LTE network is finished data service, continues in the lte networks resident.
Terminal is being determined in the network that terminal can access, for data service, the LTE network that priority is the highest performs in the process of data service, if when the signal strength signal intensity of LTE network does not reach setting intensity, terminal is by the TD-SCDMA network that can access from terminal and GSM network, continue to select for data service, the TD-SCDMA network that priority is the highest, access TD-SCDMA network continues to perform data service, terminal continues in TD-SCDMA network to perform in the process of data service, continuous detection whether can access LTE network, and when LTE network can be accessed, again access LTE network to continue to perform data service, and reside in data service when being finished, the TD-SCDMA network at terminal place or LTE network.
Certainly, terminal performs in the process of data service in LTE network, when the signal strength signal intensity of LTE network network does not reach setting intensity, if the signal strength signal intensity of TD-SCDMA network does not reach setting intensity yet, access GSM network continues to perform data service by terminal, and terminal constantly can detect whether can access TD-SCDMA network or LTE network, if can LTE network be accessed, priority access LTE network is continued to perform data service, otherwise, when the signal strength signal intensity of TD-SCDMA network reaches setting intensity, TD-SCDMA network will be accessed continue to perform data service, and constantly whether monitoring can access LTE network, once can LTE network be accessed, access LTE network continues to perform data service at once, and reside in data service when being finished, the GSM network at terminal place, TD-SCDMA network or LTE network.
Terminal is after data service is finished, reside in the network at terminal place when data service is finished, if when the signal strength signal intensity of this network does not reach setting intensity, terminal also can from the network that can access, according to the definition of standard agreement, determine the network that priority is the highest, and continue to reside in this network.
When step 203 determines the network performing data service, if this moment terminal cannot access LTE network, determine the GSM network that then can access from terminal and TD-SCDMA network for data service, the network that priority is the highest is TD-SCDMA network.
Then access TD-SCDMA network in step 204 for performing data service, and in the process performing data service, whether continuous detection can access LTE network, if can LTE network be accessed, LTE network will be accessed continue to perform data service, and reside in data service when being finished, the network at terminal place.
Embodiment three,
The embodiment of the present invention three provides a kind of method of network resident, then the steps flow chart of the method as shown in Figure 4, specifically comprises the following steps:
Access network after step 301, starting up of terminal is also resident.
Suppose in this step, terminal accesses and resides in TD-SCDMA network.
Step 302, terminal determine the priority of multinomial pending business.
Terminal, can according to the significance level of multinomial pending business when the business needing to perform is multinomial, or other factors determine the priority of multinomial pending business.
As, pending business be voice service and data service time, can according to the requirement of real-time of business setting priority.Because voice service is higher to requirement of real-time, need the preferential execution ensureing voice service, therefore voice service is set to high priority, data service is set to low priority.In the present embodiment, with pending multinomial business for voice service and data service, and voice service is set to high priority, and it is that example is described that data service is set to low priority.
Whether step 303, terminal judges TD-SCDMA network support voice service.
In the present embodiment, will judge whether the priority of first network to described pending business reaches the condition setting priority and be set as: judge whether the priority of first network to described pending business reaches the highest.
According to the network priority configuration information for voice service stored, whether terminal judges TD-SCDMA network is supported the voice service that multinomial pending business medium priority is the highest namely to judge whether TD-SCDMA network meets predetermined condition.Because TD-SCDMA network is not in the network supporting that described voice service and terminal can access (comprising GSM network and TD-SCDMA network), for voice service, the network that priority is the highest, namely, TD-SCDMA network does not meet predetermined condition, then, continue to perform step 304.
Step 304, terminal determine the network of the highest voice service of execution priority.
In this step, terminal, from the GSM network that can access and TD-SCDMA network, is determined for voice service, and the network that priority is the highest is GSM network.
Step 305, terminal access GSM network.
Terminal access GSM network performs voice service, and can judge whether GSM network supports the parallel processing of voice service and data service: when determining that GSM network can support the parallel processing of voice service and data service, perform voice service and data service simultaneously, and when voice service is finished, detect data service whether to be finished, if data service is finished, will GSM network be resided in, otherwise, perform step 306; When determining that GSM network does not support the parallel processing of voice service and data service, after voice service is finished, perform step 306.
Step 306, terminal determine the network performing data service.
The method determining the network performing data service (business that the business medium priority be not yet finished is the highest) is identical with the method determining the network performing voice service, does not repeat them here.
Step 307, terminal access and reside in the network performing data service.
Terminal accesses the network determined and performs data service, when data service is finished (when pending multinomial business is all finished), resides in the network performing data service.
By the method that the embodiment of the present invention one to embodiment four provides, after business is finished, resides in the network for performing this business, and without the need to as prior art, return to the network of high priority, to reduce between network while interoperability frequency; After terminal is started shooting first, also without the need to accessing the network of high priority, but resident in the network of access after starting shooting first, reduce further interoperability frequency between network; No matter pending business is multiple or one, the method that the embodiment of the present invention all can be utilized to provide, to realize network resident, reduces the number of times that terminal comes and goes between network; Can also by enable terminal reside in as far as possible network that terminal accesses, the network that the priority for pending business is the highest, improves the implementation quality of pending business; Meanwhile, also reserved the control interface (air interface) of network side, network side can be transmitted control message to terminal by air interface, and the method whether control terminal selects the embodiment of the present invention to provide carrys out residing network, strengthens the control of network side.
According to the method that the embodiment of the present invention one ~ embodiment three provides, provide the following terminal corresponding with the method for the embodiment of the present invention one ~ embodiment three.
Embodiment four,
The embodiment of the present invention four provides a kind of terminal, and the structural representation of this terminal as shown in Figure 5, specifically comprises the first judge module 11, second judge module 12 and accesses resident module 13, wherein:
First judge module 11 for judging whether first network supports the business that this terminal is pending, and when the business that first network does not support this terminal pending, triggers the second judge module; Second judge module 12 is for determining to support the second network of the business that this terminal is pending in the network that can access from this terminal; Access resident module 13 for when the second judge module determines to there is second network, access in the second network, and after this terminal is finished described pending business in the second network, continues to reside in second network.
The network priority configuration information for described pending business that first judge module 11 has stored specifically for basis, judge whether the priority of first network to described pending business reaches setting priority, if do not reach, then determine the first network business that support terminal is not pending; Otherwise determine the business that first network support terminal is pending.
