Abstract
A method for informing that a mobile phone is power off, busy or unreachable through a USSD message comprises the following steps; setting a flag bit P and a status bit S in a home location register (HLR); storing missing call information in the USSD center; and informing a user about the detail information of the missing call through a USSD message. The invention can record all missing calls under the circumstances that mobile phone is powered off, busy or unreachable, and send to the user when the user is available. The invention does not alter any information at a public interface, and not influence the interconnection and interflowing among manufacturers, or only adds a field in the MAP information SRI of the public interface to carry calling numbers, so as to reduce the message number transmitted among equipment and realize corresponding function with the minimum flowing.
Description
Technical field
The present invention relates to call out in the middle of the moving communicating field enhancing of related service, particularly under situations such as called subscriber's mobile phone shutdown, unreachable, engaged line, if having to call out takes place, called mobile phone then can not be answered.The relevant information of system log (SYSLOG) incoming call this moment.But when called subscriber's mobile phone time spent once more, system sends to the user with the relevant information of the phone that the user fails to answer.
Background technology
The current implementation of mobile phone is:
1. under called subscriber and situation that system normally is connected, all callings all can arrive called mobile phone, no matter whether answer, and calling party's incoming information all can leave record (comprising caller rs number, the incoming call time etc.) on called mobile phone.
2. under the situation of called subscriber's shutdown, system sends the playback notice to the calling party, as: " user that you dialed shuts down ", the called subscriber does not also know to have missed Inbound Calls.
3. can not be the called subscriber with when network normally is connected, system sends the playback notice to the calling party, as: " user that you dialed temporarily can't connect ", the called subscriber does not know that the phone incoming call is once arranged.
4. in called subscriber busy, system sends the playback notice to the calling party, as: " user that you dialed is busy, and please wait a moment dials again ", not advise called subscriber.
At present, mobile phone has become requisite means of communication in the daily life, has almost become a kind of necessity for life, on very close terms is accompanied by people.No matter be the processing of important things, still daily contact all can be used mobile phone.Exactly because its application is so general, so in case can not always worry whether to have missed some phone by mobile phone and outside normal contact.This will bring some inconvenience to the user, when especially having missed certain important incoming call, more can allow the user feel distressed.If can allow mobile phone that the user knows oneself whether incoming call be arranged in shutdown, engaged line or when unreachable, and incoming information, for the satisfaction that improves the user, the function aspects of sophisticated systems all can be perfect to some extent.
Summary of the invention
In order to address the above problem, the invention provides a kind of method, notify the user whether under shutdown, unreachable or engaged line state, Inbound Calls to be arranged with USSD message.
For achieving the above object, a kind of with the method for USSD message informing mobile phone in shutdown, engaged line or untouchable information, comprise step:
A) a flag bit P and a mode bit S are set in HLR;
B) in USSD central store missed call information;
C) use the details of the missed call that USSD message informing user misses.
The present invention can note user's all missed calls under shutdown, engaged line or unreachable situation, the user can with in send to the user.The present invention does not make an amendment to any message on the common interface, does not influence the interconnection and interflow between the manufacturer; Or only in the MAP of common interface message SRI, add a field and carry calling number, can reduce equipment room message transmitted number, realized corresponding function with minimum message flow.

Embodiment
If user shutdown, the calling party learns called shutdown in SRI Confirm message, and then the calling party with information such as the calling number of this conversation, called number, call times, sends to USSD center with USSD message with USSD message.Behind called user boot-strap, give the called subscriber with the USSD message informing.
If the user is unreachable, the calling party can not receive Call Confirm message, and behind the timer expiry, the calling party uses USSD message with information such as the calling number of this conversation, called number, call times, sends to the USSD center with USSD message.Again with after system normally is connected, give the called subscriber the called subscriber with the USSD message informing.
If user's engaged line, the calling party learns called subscriber busy in SRI Ack message, and then the calling party with information such as the calling number of this conversation, called number, call times, sends to USSD center with USSD message with USSD message.After the called subscriber discharges existing call, the incoming information that USSD center advise called subscriber is missed.
The entity that the present invention relates to comprises mobile phone, MSC/VLR, HLR, USSD center.For the RAN system, because be simple transmission, not because the present invention does any change, so do not do too much description.
For achieving the above object, and for operator provides a kind of value-added business, the present invention sets up a flag bit (hereinafter referred to as flag bit P) and a mode bit (hereinafter referred to as mode bit S) in HLR.Whether flag bit P is used for distinguishing the user and has applied for having missed the business of which phone with USSD message informing user under shutdown, engaged line or unreachable situation.Mode bit S is used for being illustrated under user's shutdown, engaged line or the untouchable situation, and whether the phone incoming call is arranged.If flag bit P is True, and applied for should business the user in shutdown, engaged line or can not under the situation of machine the phone incoming call be arranged, then system is changed to True with mode bit S, and in all missed call information of USSD central record.
Equally, if be provided with such flag bit and mode bit among the HLR, when inserting user's data, also have corresponding marker bit and mode bit among the VLR.And mode bit S can reduce message flow, promptly only when mode bit S is True, just triggers the USSD flow process, notifies the relevant information of the Inbound Calls that the user misses.
In scheme two, in MAP message SRI, increased a field, be used to carry calling number.
In addition, the USSD center need provide corresponding memory space, be used for storing the Inbound Calls that the user that applied for the missed call informing business misses under shutdown, engaged line or unreachable situation, but notify the user so that become the time spent (as start, end of conversation, position renewal etc.) again in User Status.
Under present market environment, all mobile phones are all supported USSD message, do not need extra functional development and change, as long as according to corresponding correct format display message content.
The present invention provides two kinds of solutions altogether.Because mobile phone all may miss Inbound Calls under shutdown, engaged line or unreachable situation, so followingly respectively the processing mode of missing phone under various different situations is described.
