Specific embodiment

In order that those skilled in the art more fully understand application scheme, below in conjunction with the embodiment of the present application Accompanying drawing, is clearly and completely described to the technical scheme in the embodiment of the present application it is clear that described embodiment is only this Apply for a part of embodiment, rather than whole embodiments.Based on the embodiment in the application, those of ordinary skill in the art exist The every other embodiment being obtained under the premise of not making creative work, broadly falls into the scope of the application protection.

Inventor finds, under some application scenarios, multiple different core network systems can be same use through research Family terminal provides same Subscriber Number.For example, under a kind of network architecture of possible trunking communication private network, same trunking communication Private network provides broadband cluster communication system and arrowband trunked communication system, and broadband cluster communication system can adopt the first core Net system, arrowband trunked communication system can adopt the second core network system, the first core network system and the second core network system It is different core network systems.Because the first core network system and the second core network system are all same trunking communication private networks, Same trunking communication private network can provide same Subscriber Number for same user terminal.But, traditional user terminal and core Net system also cannot be realized same user terminal and be called by multiple core network systems using same Subscriber Number.

So that same user terminal can be called by multiple core network systems using same Subscriber Number, In the embodiment of the present invention, the corresponding Subscriber Number of user terminal can be the Subscriber Number belonging to multiple core network systems.One Aspect, the call request being this Subscriber Number for calling number, this user terminal can be multiple in this Subscriber Number ownership Select for a core network system exhaled in core network system and initiate this call request to selected core network system, so should The call request that calling number is this Subscriber Number can be initiated by user terminal to different core network systems.On the other hand, The call request being this Subscriber Number for called number, the core network system receiving this call request can be in this user number Select the core network system for paging in multiple core network systems of code ownership and trigger selected core network system to this use Family terminal initiates paging, and so this user terminal can receive this Subscriber Number from different core network systems is called number Beep-page message.Therefore, same user terminal can be realized using same Subscriber Number by multiple different core network systems Called.Furthermore, because same user terminal can be using same user in multiple different core network systems Number, this user terminal can select preferably core network system to rise to exhale, can select preferably core between core network system Net system pages, such that it is able to realize the calling of ad hoc fashion, thus can improve percept of call completed, shorten call setup Time.

Illustrate, one of application scenarios of the embodiment of the present invention, may apply in the network system shown in Fig. 1.? In this network system, arrowband+broadband cluster dual-mode terminal 101 corresponds to first user number, broadband colony terminal 102 corresponding second Subscriber Number, arrowband colony terminal 103 corresponds to the 3rd Subscriber Number.Broadband cluster core net 104 and arrowband cluster core net 105 Belong to same trunking communication private network, core net 104 is connected by wide and narrow strip gateway 106 with core net 105.Wherein, first user In core net 104 and core net 105, second user number only belongs to core net 104 to number home, and the 3rd Subscriber Number is only returned Belong to core net 105.Wherein, described broadband cluster system can be for example Long Term Evolution (English：Long Term Evolution, abbreviation LTE) group system, described arrowband group system can be for example police Digital Clustering (English：Police Digital Trunking, abbreviation PDT) system or TErrestrial TRunked Radio (Terrestrial Trunked Radio) numeral Trunked communication system.

In the example of a calling procedure, terminal 101 can generate first using first user number as calling number Call request, and determine the corresponding core net of the first call request in core net 104 and core net 105, if described first exhales The corresponding core net 104 of request is made then to initiate the first call request to core net 104, if described first call request corresponds to core net Initiate the first call request to core net 105 for 105.When receiving the first call request, identification first calls core net 104 The called number of request, if the called number of the first call request corresponds to second user number, sends to terminal 102 and corresponds to The beep-page message of the first call request, if the called number of the first call request corresponds to the 3rd Subscriber Number, to core net 105 transmission the first call requests.Core net 105, when receiving the first call request, identifies the called number of the first call request Code, if the called number of the first call request corresponds to second user number, sends the first call request to core net 104, if The called number of the first call request corresponds to the paging that the 3rd Subscriber Number then sends corresponding first call request to terminal 103 Message.

In the example of another calling procedure, terminal 102 can be with the called number life corresponding to first user number Become the second call request and initiate the second call request to core net 104.Core net 104 when receiving the second call request, Identify the called number of the second call request, thus the called number recognizing the second call request corresponds to first user number. Core net 104 determines the target core network for paging first user number in core net 104 and core net 105, if target Core net is the beep-page message that core net 104 then sends corresponding second call request to terminal 101, if target core network is core Net 105 then sends the second call request to core net 105.Core net 105 when receiving the second call request, exhale by identification second It is the called number of request, thus the called number recognizing the second call request corresponds to first user number.Core net 105 to Terminal 101 sends the beep-page message of corresponding second call request.

In the example of another calling procedure, terminal 103 can be with the called number life corresponding to first user number Become the 3rd call request and initiate the 3rd call request to core net 105.Core net 105 when receiving three call requests, Identify the called number of the 3rd call request, thus the called number recognizing the 3rd call request corresponds to first user number. Core net 105 determines the target core network for paging first user number in core net 104 and core net 105, if target Core net is the beep-page message that core net 105 then sends corresponding 3rd call request to terminal 101, if target core network is core Net 104 then sends the 3rd call request to core net 104.Core net 104 when receiving three call requests, exhale by identification the 3rd It is the called number of request, thus the called number recognizing the 3rd call request corresponds to first user number.Core net 104 to Terminal 101 sends the beep-page message of corresponding 3rd call request.

It should be noted that above-mentioned application scenarios are for only for ease of the principle understanding the present invention and illustrate, it is not used in limit Fixed technical scheme provided in an embodiment of the present invention.

Below in conjunction with the accompanying drawings, method of calling in the present invention, device, terminal and core net is described in detail by embodiment The implementation of system.

Referring to Fig. 2, show a kind of schematic flow sheet of method of calling in the embodiment of the present invention.The method of the present embodiment can To be applied to first user terminal, first user terminal-pair answers first user number.Methods described for example specifically can include with Lower step：

S201, using described first user number as calling number generate the first call request.

Specifically, the user of first user terminal can operate in first user terminal, incoming call object, thus touching Sending out first user terminal please for the first calling of selected call object as calling number generation using first user number Ask.Wherein, the call object of the first call request can be a Subscriber Number, that is, the first call request is individual calling request. Or, the call object of the first call request can also be a group, that is, the first call request is to call for for the group organized Ask, the corresponding sets of numbers of this group of the called number of the first call request, the corresponding beep-page message of the first call request is for seeking Exhale the other users number in addition to first user number in group membership's number of this group.It is understood that described group of group Can include in member's number belonging to the Subscriber Number of multiple core network systems and the use only belonging to a core network system Family number.

In the present embodiment, first user terminal can provide the input mode of multiple call objects.

In some embodiments, first user terminal can preset call number list, and user can be in the first use Call object is selected in the call number list that family terminal provides.Wherein, each call object in call number list can All to have an attribute for identifying Home System, the attribute of call object is used for marking the core of this call object ownership Net system.If call object is a Subscriber Number, in call number list, the attribute of this Subscriber Number is used for marking The core network system of this Subscriber Number ownership.If call object is a group, the attribute of this group in call number list For marking the ownership processing system of this group.

In other embodiments, first user terminal can provide that presets call number to be manually entered interface, The number being manually entered manual incoming call object on interface that user can provide in first user terminal.If call object It is a Subscriber Number, then be manually entered in interface input is this Subscriber Number.If call object is a group, manually Input in inputting interface is the number of this group, wherein, can include network special in the information of input on being manually entered interface Levy code and call object.The core network system of call object ownership described in network characterization representation.

S202, determine in multiple core network systems of described first user number home described first call request correspond to Core network system.

It is understood that first user number is the Subscriber Number belonging to multiple core network systems, that is, the first use Family number be multiple core network systems open the Subscriber Number that user is used.Each core in first user number home In net system, all record has information of opening an account in this core network system for the first user number, and this information of opening an account can include first Subscriber Number and home type.It is the use only belonging to a core network system that this home type is used for identifying first user number Family number still belongs to the Subscriber Number of multiple core network systems.

It should be noted that belonging to when opening user of a core network system, user terminal in a Subscriber Number When accessing this core network system using this Subscriber Number, this user terminal needs to initiate registration to this core network system, so that should The login state of this Subscriber Number is labeled as registered state by core network system, and so this core network system passes through this user number The registered state of code can determine that this Subscriber Number is in communicable state.And for belonging to the of multiple core network systems For one Subscriber Number, a core network system not only can record this login state in its own for first user number, Login state in other core network systems for the first user number can also be recorded.Specifically, for example also may be used in the present embodiment To include：First user terminal sends described first user to described first core network system of described first user number home The register command of number, so that the first login state of described first user number is set to by described first core network system Login state, and the first login state of described first user number, wherein, described the is sent to described second core network system First login state of one Subscriber Number is used for representing whether described first user number is registered to described first core net system System；First user terminal sends described first user number to described second core network system of described first user number home Register command so that described second core network system the second login state of described first user number is set to registered State, and the second login state of described first user number is sent to described first core network system, wherein, described first use Second login state of family number is used for representing whether described first user number is registered to described second core network system；Institute The first login state stating first user number is registered state, represents described first user number and described first core net System is in communicable state；Second login state of described first user number is registered state, represents described first use Family number and described second core network system are in communicable state.

It is understood that for a Subscriber Number and a core network system, only returning in this Subscriber Number In the case of belonging to this core network system, the login state that Subscriber Number is only possible in core network system is registered state. Therefore, if login state in this core network system for this Subscriber Number is registered state, this Subscriber Number belongs to this Core network system and this Subscriber Number and this core network system are in communicable state.

In some embodiments of the present embodiment, described first call request can be asked for individual calling, i.e. the first calling The call object of request only includes a Subscriber Number.Assume to be the as the called number of the first call request of individual calling request Two Subscriber Numbers, now, first user terminal can select to be used for according to the core network system that second user number is belonged to Initiate the core network system of this individual calling request.Specifically, S202 for example can include：Many in described first user number home The core network system of described second user number home is determined in individual core network system；If described second user number only belongs to First core network system, determines that described first call request corresponds to described first core network system；If described second user number Only belong to the second core network system, determine that described first call request corresponds to described second core network system；If described second Subscriber Number belongs to multiple core network systems, selects wireless in multiple core network systems of described second user number home Access the best core network system of signal as the corresponding core network system of described call request, wherein, described wireless access letter Number best core network system is described first core network system or described second core network system.As can be seen here, when individual calling please When the called number asked only belongs to a core network system, the called number institute that first user terminal can be asked by individual calling Ownership core network system initiate this individual calling request, so so that the calling between first user number and called number only Across core network system realization is achieved without by a core network system, thus improve percept of call completed, shortening calling The time set up.When the called number of individual calling request belongs to multiple core network system, first user terminal can select letter Number best core network system initiates the request of this individual calling, so so that calling between first user terminal and called number Realized by the best core network system of signal, thus improve percept of call completed, shortening time of call setup.

In other embodiments of the present embodiment, described first call request can be that the group for group is called for asking, That is, the call object of the first call request is a group, and the called number of the first call request is described group of corresponding sets of numbers, The corresponding beep-page message of first call request is used for other in described group of group membership's number in addition to first user number Subscriber Number..For example, it is assumed that described group of group membership's number includes described first user number and described second user number Code, then the corresponding beep-page message of the first call request can be used for paging second user number.Exhale for group in the first call request In the case of request, group can be called for asking corresponding group of ownership processing system to call for asking as initiation group by first user terminal Core network system.Specifically, S202 for example can include：In multiple core network systems of described first user number home Determine described group of ownership processing system；Wherein, described group of ownership processing system is a unique core network system；If institute The ownership processing system stating group is the first core network system, determines corresponding described first core network system of described request；If described The ownership processing system of group is the second core network system, determines that described first call request corresponds to described second core network system.

Although it is understood that each group membership's number in group may belong to multiple different core network systems, Can only have a core network system in this multiple different core network system is the ownership processing system organized.Specifically, exist When setting up call service group, this group needs to open an account on a core network system, and the core network system for this group of opening an account is this group Ownership processing system.The visit office of each group membership's number in this group can be recorded in the ownership processing system of this group Number, the visit office number of group membership's number is used for identifying the core network system of the current visit of this group membership's number.Wherein, in group Group membership's number for, this group membership's number can be the Subscriber Number of the ownership processing system belonging to this group, It can be the Subscriber Number of the ownership processing system not belonging to this group.

It should be noted that the present embodiment can not limit to the execution sequence of S201 and S202.For example, originally Embodiment can first carry out S201 and generate the first call request, then executes S202 and determine the core for initiating the first call request Net system.And for example, the present embodiment can first carry out S202 and determines core network system for initiating the first call request, then executes S201 generates the first call request.For another example, the present embodiment S201 and S202 can execute simultaneously, and first user terminal is being held During row S201 generates the first call request, execution S202 determines the system for initiating the first call request.

If described first call request of S203 corresponds to the first core network system, initiate institute to described first core network system State the first call request, so that described first core network system identifies the called number of described first call request, triggering is described The first object core network system of the called number ownership of the first call request is to the called number pair of described first call request The second user terminal answered sends the first beep-page message of corresponding described first call request.

Specifically, the first core network system, when receiving the first call request, can identify the first call request The corresponding Subscriber Number of called number.Assume that the called number of the first call request corresponds to fourth user number and fourth user Number corresponds to second user terminal, the registration shape of the fourth user number that the first core network system can preserve according to its own State, selects the first object core net system for paging fourth user number in the core network system of fourth user number home System.If the first login state of fourth user number is not note for the second login state of registered state and fourth user number Volume state, the first core network system can select the first core network system as first object core network system, trigger its own Send the first beep-page message to second user terminal.If the first login state of fourth user number is unregistered state and the 4th Second login state of Subscriber Number is registered state, and the first core network system can select the second core network system as the One target core network system, sends the first call request to the second core network system, to trigger the second core network system to second User terminal sends the first beep-page message.If the first login state of fourth user number and the second login state are registered State, the first core network system can select according to preset strategy in the first core network system and the second core network system One target core network system.

It should be noted that in the case that the first call request is for individual calling request, the called number of the first call request Corresponding to fourth user number, represent, fourth user number is the called number of the first call request.And in the first call request In the case of calling for asking for group, the called number of the first call request corresponds to fourth user number, represents, fourth user number Group membership's number for corresponding group of the called number of the first call request.

It is understood that in the case of being to call for asking for the group organized in the first call request, the first core network system When receiving the first call request, for each group membership's number in addition to first user number, the first core in group The beep-page message that net system can trigger corresponding first call request is sent out to each corresponding user terminal of group membership's number described Send.

If described first call request of S204 corresponds to the second core network system, initiate institute to described second core network system State the first call request, so that described second core network system identifies the called number of described first call request, triggering is described Second target core network system of the called number ownership of the first call request is to the called number pair of described first call request The 3rd user terminal answered sends the second beep-page message of corresponding described first call request.

Specifically, the second core network system, when receiving the first call request, can identify the first call request The corresponding Subscriber Number of called number.Assume that the called number of the first call request corresponds to the 5th Subscriber Number and the 5th user Number corresponds to the 3rd user terminal, the registration shape of the 5th Subscriber Number that the second core network system can preserve according to its own State, selects the second target core network system for paging the 5th Subscriber Number in the core network system of the 5th Subscriber Number ownership System.If the first login state of the 5th Subscriber Number is to note for the second login state of unregistered state and the 5th Subscriber Number Volume state, the second core network system can select the second core network system as the second target core network system, trigger its own Send the second beep-page message to the 3rd user terminal.If the first login state of the 5th Subscriber Number is registered state and the 5th Second login state of Subscriber Number is unregistered state, and the second core network system can select the first core network system as the Two target core network systems, send the first call request to the first core network system, to trigger the first core network system to the 3rd User terminal sends the second beep-page message.If the first login state of the 5th Subscriber Number and the second login state are registered State, the second core network system can select according to preset strategy in the first core network system and the second core network system Two target core network systems.

It should be noted that in the case that the first call request is for individual calling request, the called number of the first call request Corresponding to the 5th Subscriber Number, represent, the 5th Subscriber Number is the called number of the first call request.And in the first call request In the case of calling for asking for group, the called number of the first call request corresponds to the 5th Subscriber Number, represents, the 5th Subscriber Number Group membership's number for corresponding group of the called number of the first call request.

It is understood that in the case of being to call for asking for the group organized in the first call request, the second core network system When receiving the first call request, for each group membership's number in addition to first user number, the second core in group The beep-page message that net system can trigger corresponding first call request sends to each group membership's number.

In the present embodiment, first user terminal is except can be using first user number as calling number to multiple differences Core network system rise and exhale, can also be received from multiple different core net systems using first user number as called number The paging of system.Specifically, the present embodiment for example can also include：The 3rd paging receiving described first core network system transmission disappears Breath, described 3rd beep-page message corresponds to the second call request, and the called number of described second call request corresponds to described the One Subscriber Number；Receive the 4th beep-page message that described second core network system sends, described 4th beep-page message corresponds to the Three call requests, the called number of described 3rd call request corresponds to described first user number.It is understood that In the case that two call requests are for individual calling request, the called number of the second call request corresponds to first user number, represents, the One Subscriber Number is the called number of the second call request.And in the case that the second call request is called for asking for group, second exhales The called number crying request corresponds to first user number, represents, first user number is the called number of the second call request Corresponding group of group membership's number.Additionally, in the case that the 3rd call request is for individual calling request, the 3rd call request Called number corresponds to first user number, represents, first user number is the called number of the 3rd call request.And the 3rd In the case that call request is called for asking for group, the called number of the 3rd call request corresponds to first user number, represents, first Subscriber Number is group membership's number of corresponding group of the called number of the 3rd call request.

In some embodiments, for the call request using first user number as called number, can be only by The core network system selected in multiple core network systems of described first user number home is sent to first user terminal, That is, for same call request, first user terminal can only receive once to should call request beep-page message.

In other embodiments, for the call request using first user number as called number, can be by Multiple core network systems of described first user number home send first user terminal respectively, that is, for same calling Request, first user terminal can receive repeatedly to should call request paging request.First user terminal can be therefrom Choose a beep-page message and retain and abandon other beep-page messages, such first user terminal just have selected a core net system Unite and to carry out this calling.Specifically, the present embodiment for example can also include：First user terminal is described in the correspondence receiving Determine the beep-page message being initially received in all beep-page messages of the second call request, abandon except described be initially received seek Exhale the beep-page message of other corresponding described second call requests outside message.Wherein, described second call request and the described 3rd Call request is same call request.Described second call request is to be sent to described first core net system by the 3rd user terminal System is simultaneously sent to described second core network system by described first core network system, or, described second call request is by the Three user terminals are sent to described second core network system and are sent to described first core net by described second core network system System.

It should be noted that the present embodiment can apply to multiple different core network systems providing for same user terminal Under any scene of same general Subscriber Number.For example, described first core network system can be broadband trunking communication system System, described second core network system can be arrowband trunked communication system, described first core network system and described second core Net system is belonging to same trunking communication private network.Now, first user terminal can be the bimodulus end of arrowband+broadband cluster End, second user terminal can be broadband colony terminal or the dual-mode terminal of arrowband+broadband cluster, and the 3rd user terminal can be Arrowband colony terminal or the dual-mode terminal of arrowband+broadband cluster.In aforementioned call list of numbers, the attribute of call object can be used Terminal standard in mark call object.Aforementioned network condition code can be used for identifying the terminal standard of call object.Aforementioned Home type can be used for identifying the pattern of first user number.

By the technical scheme of the present embodiment, the corresponding Subscriber Number of user terminal can be to belong to multiple core net systems The Subscriber Number of system.On the one hand, the call request being this Subscriber Number for calling number, this user terminal can be in this user Select in multiple core network systems of number home to initiate to be somebody's turn to do for a core network system exhaled and to selected core network system Call request, so this user terminal can by calling number be this Subscriber Number call request to different core network systems Initiate.On the other hand, the call request being this Subscriber Number for called number, receives the core network system of this call request The core network system for paging can be selected and trigger selected core in multiple core network systems of this Subscriber Number ownership Heart net system initiates paging to this user terminal, and so this user terminal can receive this user number from different core network systems Code is the beep-page message of called number.Therefore, same user terminal can be realized using same Subscriber Number by multiple not Same core network system is called.Furthermore, because same user terminal can be in multiple different core network systems Middle using same Subscriber Number, this user terminal can select preferably core network system to rise to exhale, permissible between core network system Select preferably core network system paging such that it is able to realize the calling of ad hoc fashion, thus can improve percept of call completed, Shorten the time of call setup.

Referring to Fig. 3, show a kind of schematic flow sheet of method of calling in the embodiment of the present invention.The method of the present embodiment can To be applied to the first core network system, methods described for example specifically may comprise steps of：

S301, receive the first call request that first user terminal sends, the calling number of described first call request is The corresponding first user number of described first user terminal.

Wherein, as the calling number of the first call request, first user number can be only to belong to the first core net The Subscriber Number of system, or, first user number can also be the multiple cores belonging to including the first core network system The Subscriber Number of heart net system.It is understood that when first user number belongs to multiple core network system, first user terminal The corresponding core network system of the first call request can be determined in multiple core network systems of first user number home, if the Corresponding first core network system of one call request then can send the first call request to the first core network system, hence into The execution of S301.If additionally, during corresponding second core network system of the first call request, first user terminal can be to the second core Net system sends the first call request.It can be seen that, when first user number home is in multiple core network system, with first user number Code can be initiated by multiple different core network systems as the first call request of calling number.

S302, the called number of described first call request of identification.

In the present embodiment, the call object of the first call request can be a Subscriber Number, that is, the first calling please Seeking Truth individual calling is asked, and this called number is second user number.Or, the call object of the first call request can also be one Individual group, that is, the first call request is to call for asking for the group organized, the called number of the first call request is corresponding group of this group Number, the corresponding beep-page message of the first call request be in group membership's number of this group of paging in addition to first user number Other users number, for example, described group of group membership's number can include first user number and second user number.Described The ownership processing system of group is described first core network system, and described group of ownership processing system is a unique core net system System.It is understood that described group of group membership's number can include belonging to the Subscriber Number and only of multiple core network systems Belong to the Subscriber Number of a core network system.

It is understood that in the case of being to call for asking for the group organized in the first call request, the first core network system When receiving the first call request, for each group membership's number in addition to first user number, the first core in this group The beep-page message that heart net system can trigger corresponding first call request sends to each group membership's number.

S303, the called number in response to described first call request correspond to second user number, in the described second use The target core network system for second user number described in paging is determined in multiple core network systems of family number home.

In the present embodiment, in the case that the first call request is for individual calling request, the called number of the first call request Corresponding to second user number, represent, second user number is the called number of the first call request.And in the first call request In the case of calling for asking for group, the called number of the first call request corresponds to second user number, represents, second user number Group membership's number for corresponding group of the called number of the first call request.

It is understood that second user number is the Subscriber Number belonging to multiple core network systems, that is, the second use Family number is the user identification code being common to multiple core network systems, second user number be multiple core network systems open use The Subscriber Number that family is used.In each core network system of second user number home, all record has second user number to exist Information of opening an account in this core network system, this information of opening an account can include second user number and home type.This home type It is only to belong to the Subscriber Number of a core network system or belong to multiple core net systems for identifying second user number The Subscriber Number of system.

It should be noted that belonging to when opening user of a core network system, user terminal in a Subscriber Number When accessing this core network system using this Subscriber Number, this user terminal needs to initiate registration to this core network system, so that should The login state of this Subscriber Number is labeled as registered state by core network system, and so this core network system passes through this user number The registered state of code can determine that this Subscriber Number is in communicable state.It can be seen that, for a Subscriber Number and a core For heart net system, only in the case that this Subscriber Number belongs to this core network system, Subscriber Number is only possible in core Login state in net system is registered state.If login state in this core network system for this Subscriber Number is registered State, then this Subscriber Number belongs to this core network system and this Subscriber Number is in communicable state with this core network system. Therefore, the first core network system can be according to login state in its own for the second user number and in the second core net system Login state in system, determines that the core network system of second user number home and second user number are in communicable state Core network system, thus be assured that the target core network system for paging second user number.Specifically, in this enforcement In example, in described first core network system, for example can record the first login state and second note of described second user number Volume state, now S303 can include：According to described first login state and described second login state, determine presently described The core network system that two Subscriber Numbers can communicate；In the core network system that described presently described second user number can communicate really The fixed described target core network system for second user number described in paging.Wherein, if described first login state is to note Volume state, the core network system that described presently described second user number can communicate includes described first core network system, if institute Stating the second login state is registered state, and the core network system that described presently described second user number can communicate includes described Second core network system.

If it is understood that determining that multiple current second user numbers can according to the login state of second user number The core network system of communication, the core that the first core network system can be able to communicate from multiple current second users according to preset strategy The core network system for paging second user number is selected in heart net system.For example, a kind of strategy is, the first core net system System can only select the first core network system conduct itself in the core network system that multiple current second user numbers can communicate For the target core network system of paging second user number, thus without other core network systems to the first call request again Processed, thus having saved Internet resources.And for example, another kind of strategy is, the first core network system is multiple current second The first core network system and all conducts of the second core network system can be selected in the core network system that Subscriber Number can communicate to be used for The target core network system of paging second user number, so can improve calling in the case that Internet resources are more loose and connect Passband.For another example, a kind of strategy is had to be, the core net system that the first core network system can communicate in multiple current second user numbers The core network system specified can be selected in system as target core network, the core network system such as specified can be the second core net System.

Additionally, when target core network system is determined according to the login state of second user number, multiple for belonging to For the second user number of core network system, the first core network system not only can record this first user number at its own In login state, login state in other core network systems for the first user number can also be recorded.Specifically, this enforcement Example for example can also include：Receive the register command of the described second user number that described second user terminal sends, will be described First login state of second user number is set to registered state, and sends described second to described second core network system First login state of Subscriber Number；Receive the second registration of the described second user number that described second core network system sends State, the second login state of described second user number is that described second core network system is receiving described second user eventually It is set to registered state after the register command of described second user number that end sends and be sent to described first core net System.Wherein, the first login state of described second user number is used for representing whether described second user number is registered To described first core network system.Second login state of described second user number is used for representing that described second user number is No it is registered to described second core network system；First login state of described second user number is registered state, represents Described second user number and described first core network system are in communicable state；Second registration of described second user number State is registered state, represents that described second user number and described second core network system are in communicable state.

If S304 described target core network system is described first core network system, correspond to described second user number Second user terminal send the first beep-page message of corresponding described first call request.

If S305 described target core network system is the second core network system, send institute to described second core network system State the first call request, so that described second core network system sends to the corresponding second user terminal of described second user number Second beep-page message of corresponding described first call request.

Additionally, target core network system potentially includes multiple core network systems.In this regard, the present embodiment for example can also wrap Include：If described target core network system includes described first core network system and described second core network system, to described Two user terminals send described first beep-page message, and send described first call request to described second core network system, with Toilet is stated the second core network system and is sent described second beep-page message to described second user terminal.Wherein, described first paging Message and described second beep-page message are used in described first call request of the correspondence receiving by described second user terminal Determine the beep-page message being initially received in all beep-page messages and abandon in addition to the described beep-page message being initially received it The beep-page message of his corresponding described second call request.

It is understood that the first core network system is except being the called user belonging to multiple core network systems Number triggers the transmission of beep-page message, can also be for only belonging to the called Subscriber Number triggering paging of a core network system The transmission of message.Specifically, the present embodiment for example can also include：Receive the second call request that the 3rd user terminal sends, The calling number of described second call request is corresponding 3rd Subscriber Number of described 3rd user terminal；Identify that described second exhales It is the called number of request, the called number of described second call request corresponds to fourth user number, described fourth user number Code only belongs to a core network system；If the core network system of described fourth user number home is described first core net system System, the 3rd paging sending corresponding described second call request to the corresponding fourth user terminal of described fourth user number disappears Breath；If the core network system of described fourth user number home is the second core network system, to described second core network system Send described second call request, so that described second core network system is to the corresponding fourth user of described fourth user number eventually End sends the 4th beep-page message of corresponding described second call request.

It is understood that the first core network system can select for paging according to the login state of fourth user number The core network system of fourth user number.Specifically, the first core network system according to the login state of fourth user number to the The login state of the paging way of four Subscriber Numbers and aforementioned first core network system foundation second user number is to second user The paging way of number is similar.Therefore, the first core network system may refer to aforementioned to the paging way of fourth user number The paging way to second user number for one core network system.

Additionally, in the present embodiment, aforementioned first call request and aforementioned second call request can be for same Call for asking for same group of group.Now, the calling number asked, described first user number and described 3rd use is called for as this group Family number is same Subscriber Number.Group membership's number of this group actually at least includes first user number, second user Number and fourth user number.Wherein, as group membership's number of this group, second user number is to belong to multiple core net systems The Subscriber Number of system, fourth user number is the Subscriber Number only belonging to a core network system.

It should be noted that the present embodiment can apply to multiple different core network systems providing for same user terminal Under any scene of same general Subscriber Number.For example, described first core network system can be broadband trunking communication system System, described second core network system can be arrowband trunked communication system, described first core network system and described second core Net system is belonging to same trunking communication private network.Now, second user terminal can be the bimodulus end of arrowband+broadband cluster End, first user terminal can be the dual-mode terminal of broadband colony terminal, arrowband colony terminal or arrowband+broadband cluster, the 3rd User terminal can be the dual-mode terminal of broadband colony terminal, arrowband colony terminal or arrowband+broadband cluster, fourth user terminal Can be broadband colony terminal or arrowband colony terminal.In aforementioned call list of numbers, the attribute of call object can be used for marking The terminal standard of call object.Aforementioned home type could be for identifying the dual mode type of the terminal standard of first user number (Dual).And for example, described first core network system can also be arrowband trunked communication system, and described second core network system also may be used To be broadband cluster communication system, it is special that described first core network system and described second core network system belong to same trunking communication Net.

It is understood that " second user number " in the present embodiment can correspond to the embodiment shown in aforementioned Fig. 2 In " first user number ", the specific embodiment in the specific embodiment of the present embodiment and the embodiment shown in Fig. 2 can Cross-referenced.
