CN1251472C - Method for implementing selective incoming call processing - Google Patents

The present invention provides a method for achieving incoming call selective treatment, which comprises the following steps: (a), a calling party initiates a call through a calling start MSC of the calling party, and route taking operation is initiated by the calling start MSC to an HLR of a called party; (b), a calling number is taken out from a message of the route taking operation of the calling start MSC by the HLR of the called party; (c), the calling number and a controlled number is matched by the HLR of the called party to obtain a matching result; (d), an incoming call is selected and treated by the HLR of the called party according to the matching result. A powerful incoming call selective treatment function can be achieved under the preconditions that extra equipment does not need adding, specific requirements do not need specifying for a mobile phone and a standard mobile communication protocol does not need any making change. The present invention has the advantages of simple scheme, broad application ranges, speech path saving and flexible controlled manner, and the setting method of the controlled number is more flexible.

A kind of realize sending a telegram here select the method handled

Technical field

The present invention relates to the mobile communication technology field, relate to specifically a kind of realize sending a telegram here select the method handled.

Background technology

Along with constantly popularizing of mobile communication, for the user brings very big facility, the user also has higher requirement to mobile communication simultaneously " carrying out communication whenever and wherever possible ".The user wishes sometimes and can selectively handle incoming call, comprises and inserting or refusal, rather than all refusal or all access.Specifically, comprise the number that only inserts appointment, all reply " Called Busy " or " called out of reach " processing for the calling that other number is initiated, the calling party is carried out " courtesy refusal ", so just avoided owing to shutdown or refusal are answered losing important call or bringing injury to the calling party of bringing by force; Sometimes, just the opposite again, the user only wishes " soft refusal " several assigned numbers, and all inserts for the calling of other number.

There are three kinds at this type of demand prior art solutions: realize, realize, realize by Intellight network mode by HLR at network side by mobile phone terminal.Introduce these three kinds below respectively

Prior art:

First method is to realize by mobile phone terminal.The user is this professional relevant parameter of registration on the mobile phone of supporting this function directly, comprises controlled number, controlled character (" only inserting " still is the number that " only refusal " is registered).Like this, after the speech channel between the calling and called was switched on, the number of registering in calling number that called mobile phone carries according to the caller signaling and the mobile phone mated, and decided refusal or insert according to service parameter in the mobile phone.

Second method is to realize by Intellight network mode: on common mobile network basis, Service Switching Point) and SCP (Service Control Point: service control point) increase independently intelligent equipment, comprise SSP (Service Switching Point:.The user registers to service parameter among the SCP by mobile phone or business hall, realizes the business function of appointment then by the IN service processing logic of standard.

The third method is to realize by HLR.Its realization is fairly simple, but only support access on the function to assigned number, and do not support refusal to assigned number, the SCA under the CDMAANSI664 agreement (Selective Call Acceptance: optional calling insert) function for example, it supports the coupling fully of incoming call and assigned number, when promptly having only calling number and specifying controlled number identical, select to insert just effective.

Yet there are many deficiencies in above-mentioned prior art, particularly comprises:

In the first method, at first business is subject to terminal equipment fully, because the mobile phone of this characteristic of support also seldom, the most mobile phones on the market are not supported this project function, so professional universal scope is very little, for operator, does not have scale and benefit; Secondly speech channel is caused waste, under this programme, have only and just can come into force after setting up speech channel between the calling and called mobile phone fully, if this moment, shielding came into force, this is just called out and handles according to failure so, operator will waste to this and call out fixed line speech channel and the aerial speech channel that is distributed this moment, and this is difficult to accept to the operator that emphasizes call completing rate.

The second method investment is big, the cost height, owing in the zone of not supporting intelligent network, also will additionally build required SSP of intelligent network and SCP equipment, investment is high, and the cycle is long; For also not possessing at present the rich inadequately operator of last intelligent network conditioned disjunction fund ability, can not carry out this business.

The third methodological function is more single, can only support controlled telephone is inserted, and not support " soft refusal " controlled telephone, such as to certain, certain is several or " the soft refusal " of certain class phone; Controlled area charactert is dumb in addition, can only support the full coupling of caller ID and assigned number, and does not support the part matching feature by " number head " matching way.In actual applications, the user not only needs to specify all number sign indicating number to carry out controlled to certain usually, tend to carry out controlled to certain type number, such as to by national code controlled to certain country incoming call, by ground area code controlled to somewhere incoming call, by certain city area code controlled etc. to a certain city number.

Summary of the invention

At said circumstances, the present invention proposes does not a kind ofly need to increase extras, does not need mobile phone terminal is done specific (special) requirements and the mobile communication agreement of standard do not done under the prerequisite of any change, on the basis of existing network HLR, only the parameter of incoming call being selected to handle by increase is stepped on the method that the affair processing logic just can realize that powerful incoming call selection is handled.

For achieving the above object, the present invention proposes a kind of realize sending a telegram here select the method handled, this method comprises following steps:

A, caller exhale moving exchanging center MSC to make a call by the affiliated beginning, and this beginning exhales moving exchanging center MSC to initiate to get routing operations to called attaching position register HLR;

B, called attaching position register HLR exhale moving exchanging center MSC to get the message of routing operations from this beginning and take out calling number;

C, called attaching position register HLR mate the controlled number of calling number and called registration, judge whether calling number is included in the controlled number or number first table of called registration, thereby to obtain be allow to insert or do not allow the matching result that inserts;

D, called attaching position register HLR according to matching result promptly according to whether allowing to insert the processing of selecting the processing that incoming call carries out subsequent logic is still sent Reason For Denial.

Wherein, described step c more specifically may further comprise the steps:

Whether c1, called attaching position register HLR judge called signatory and activated incoming call and selected to manage business, if carry out next step so, otherwise matching result inserts for allowing caller;

C2, judge calling number whether be included in controlled number or number first the table in, if carry out next step, otherwise judge that called whether being provided with only insert controlled incoming call, if matching result inserts for not allowing caller so, otherwise matching result inserts for allowing caller;

C3, judge that called whether being provided with only refuse controlled incoming call, if matching result inserts for not allowing caller so, otherwise matching result inserts for allowing caller.

Described steps d more specifically may further comprise the steps:

If the d1 matching result inserts for allowing caller, so called attaching position register HLR carries out the processing of the subsequent logic of standard, otherwise carries out next step;

D2, called attaching position register HLR set Reason For Denial, and exhale moving exchanging center MSC to send to caller by the beginning this Reason For Denial.

The present invention is not needing to increase extras, is not needing mobile phone terminal done specific (special) requirements and the mobile communication agreement of standard is not done under the prerequisite of any change, by existing network HLR device interior is done a small amount of adjustment, promptly on the basis of existing network HLR, increase parameter registration and the business processing logic of selecting processing to sending a telegram here and just can realize the function that powerful incoming call selection is handled.Particularly, it has following advantage:

3, save speech channel; Because user's shielding parameter all is registered among the HLR; so just can being provided with according to the user, the Signalling exchange stage HLR before speech channel is set up select refusal to call out or replay call; therefore save fixed line speech channel and aerial speech channel, greatly protected benefits of operators.

4, controlled way is flexible; Not only the incoming call that only inserts specified scope can be set, the incoming call of only refusing specified scope can also be set.

5, the setting means of controlled number is more flexible; Not only can set some or certain several number, can also carry out the part coupling, increase the setting range of controlled number, make every function more flexible by number mode of first coupling.

Specific implementation

The embodiment of the invention is described to realize the method that the incoming call selection is handled by HLR, and it is applied to present widely used CDMA (Code Division Multile Addressing: network code division multiple access).In the service area in this network, comprise: calling subscriber A, the mobile base station), MSC (Mobile Service Switching Center: mobile services switching centre), HLR called subscriber B and for the two provides (the Mobile Station: of MS separately of service.

Before describing the described method of selecting to handle that realizes sending a telegram here by HLR of the embodiment of the invention, at first carry out two following work.

1, on above-mentioned existing network HLR, increases storage, the sign on function of incoming call being selected the processing capacity parameter.

The functional parameter that user's incoming call is selected to handle comprises: the controlled number and the controlled way (being to insert or the controlled number of refusal) that contract/go signatory state, activation state, registration.This traffic performance has only the user signatory and activated under this professional situation and just come into force.About function.

The functional parameter that user's incoming call is selected to handle comprises: the controlled number and the controlled way (being to insert or the controlled number of refusal) that contract/go signatory state, activation state, registration.This traffic performance has only the user signatory and activated under this professional situation and just come into force.

According to the management practice of mobile service attribute, the user of incoming call selection is managed business contract and go contracted because may relate to charging, generally can only safeguard by the business hall; The registration of controlled way, controlled number, the activation of traffic performance, deactivation require promptly can be undertaken by business hall (perhaps service hotline), also can operate by the mobile phone operation sign indicating number of standard, to make things convenient for the flexible use of characteristic.

Particularly comprise: Ying Yetingjiekou and the Operation and Maintenance interface of expansion HLR user data content, expansion HLR, increase activate, operation command code that the deactivation incoming call is selected to manage business is (such as activating with 88, deactivation is with 89, occurrence can be specified according to actual conditions by each operator), and expand among the HLR increasing the processing logic of command code newly.

2, increase the processing logic of incoming call being selected processing capacity at existing network HLR.

To the effect that transform HLR to the called processing logic of getting route messages, promptly after receiving LOCREQUEST message, as shown in Figure 4, handle according to following service logic according to the incoming call of the calling number of carrying in the message and the user registration processing capacity parameter of selecting to manage business.

After obtaining user's calling number LOCREQ (the called route of the getting) message that beginning under user A exhales MSC to initiate, carry out following logic determines:

{ { IF (user is provided with and only refuses controlled incoming call) { is set to AccessDeniedReason parameter and AnnouncementList " No Page Response calls out does not have response " (also can set a user is busy, user's shutdown) to IF (calling number is included in the controlled number or number first table of user's registration) to IF (user is signatory and activated incoming call and selected to manage business) simultaneously; Above two parameters are exhaled MSC by the locreq message feedback to the beginning;＜!--SIPO＜DP n=" 5 "〉--〉＜dp n=" d5 "/EXIT (finishing processing logic) to LOCREQ message; ELSE//this moment calling number is not included in controlled number (or number head) scope that { IF (user is provided with and only inserts controlled incoming call) { is set to AccessDeniedReason parameter and AnnouncementList " No Page Response calls out does not have response " (also can set a user is busy, user's shutdown) simultaneously; Above two parameters are exhaled MSC by the LOCREQ message feedback to the beginning; EXIT (finishing processing logic) to LOCREQ message;

Continuation is got the processing that the route flow process is carried out subsequent logic according to the standard of ANSI41D definition is called;

The core content of the embodiment of the invention is on the basis of existing network HLR, the parameter that increase is selected to handle to incoming call is registered and business processing logic: promptly when HLR gets the route messages flow process according to the processing of standard mobility protocol is called, according to being provided with of user called signaling is carried out intercept analysis.

Below just with CDMA ANSI-41D agreement flow process to allow inserting and two kinds of workflows of courtesy refusal, promptly corresponding two embodiment illustrate the present invention.

Embodiment one: user A calls out signatory and has activated to send a telegram here and selected the user B of processing capacity, and user B allows A to insert:

As shown in Figure 1, it may further comprise the steps:

The first, caller exhales MSC to make a call by the affiliated beginning, and this beginning exhales MSC to initiate to get routing operations to called ownership HLR;

1, mobile subscriber A makes a call to user B by place service MSC;

2, the beginning exhales MSC to initiate to get routing operations to the ownership HLR of called subscriber B, wherein obtains matching result.

3, HLR registers controlled number (perhaps number head) with the number (being calling number) of calling subscriber A and user B and mates, and finds to allow A to insert, and obtains matching result.

Four, called ownership HLR selects to handle to incoming call according to matching result.

Follow-up gets routing operations shown in the step 4 among Fig. 2,5,6, and these message flows and message interface are fully consistent with the CDMA standard agreement.

4, at first the MSC of user B place service distributes interim roaming number TLDN (Temporary Local Directory Number:CDMA mobile subscriber temporary number book number), and feeds back to HLR;

5, HLR feeds back to TLDN and begins to exhale MSC;

6, the beginning exhales MSC to initiate replay call according to TLDN to user B.

Embodiment two: user A calls out signatory and has activated to send a telegram here and selected the user B of processing capacity, and user B does not allow A to insert:

As shown in Figure 1, it may further comprise the steps:

The first, caller exhales MSC to make a call by the affiliated beginning, and this beginning exhales MSC to initiate to get routing operations to called ownership HLR;

The second, called ownership HLR exhales MSC to get the message of routing operations from this beginning and takes out calling number.

Three, called ownership HLR mates the controlled number of calling number and called registration, obtains matching result.

3, HLR registers controlled number (perhaps number head) with the number (being calling number) of calling subscriber A and user B and mates, and finds not allow A to insert, and obtains matching result,

Four, called ownership HLR selects to handle to incoming call according to matching result.

3, HLR registers controlled number (perhaps number head) with the number (being calling number) of calling subscriber A and user B and mates, and finds not allow A to insert, and obtains matching result,

Four, called ownership HLR selects to handle to incoming call according to matching result.

Following message flow and message interface are fully consistent with the CDMA standard agreement, shown in the middle as shown in Figure 3 step 4,

4, after the beginning exhales MSC according to the message that receives HLR feedback, the voice suggestion of playing " call out and do not have response " or " user is busy " " user's shutdown " to user A according to the AccessDeniedReason and the AnnouncementList parameter value of HLR appointment.These two parameters and parameter value are all consistent with standard agreement, do any adjustment so need not MSC.
