Description
Technical field
The present invention relates to a kind of communication technology, relate in particular to a kind of communication means and system, reach mobile switching centre.
Background technology
In actual applications, certain user needs two terminals, and these two terminals have identical SIM (Subscriber Identity Module; User identification module) card promptly has identical IMSI (International Mobile Subscriber Identity, IMSI International Mobile Subscriber Identity).As, the user has a mobile phone and a Vehicle mounted station, as this user not onboard the time, uses mobile phone and other user terminal to communicate; As this user onboard the time, use Vehicle mounted station and other user terminal to communicate.Like this, use jack per station to compare, have following benefit with each terminal: for same user, the collision problem that is produced in the time of at first can not causing two terminals of jack per station to communicate by letter simultaneously; Secondly, when with other telex network, can make the user utilize the terminal of most convenient to communicate, as, as this user onboard the time, use Vehicle mounted station and other terminal to communicate, other situation, use mobile phone and miscellaneous equipment communicate; The 3rd, can use same account to charge, promptly make things convenient for network billing, also can make things convenient for subscriber payment.
Yet the inventor finds in the invention process, in the existing communication system, only allows the terminal of a unique IMSI, and IMSI is globally unique IMSI International Mobile Subscriber Identity, and it writes in the SIM card usually.Because two terminals are used identical SIM card in communication system, promptly use identical IMSI, be that communication system protocol institute is unallowed, thereby make present system can't satisfy this demand.
In existing systems, why do not allow two terminals to use identical IMSI, reason is, all be to be the data that sign is distinguished user storage with IMSI in the time of storage of subscriber data, these data comprise user's business data signed, and the required information and the data of some system handles flow processs of interim storage in the customer service process.If the user of two identical IMSI signs in to system simultaneously, what can cause that two users' service access flow process or position upgrade that flow processing relied on is the user contracting data and the conflict of user's flow process temporary information of unique sign index with user ID.Here said position is upgraded, and comprises switching on and shutting down, general position renewal, various situations such as periodic location update.Here said service access comprises that miscellaneous services such as voice, data, short message insert.
As shown in Figure 1, suppose to have IMEI (the International Mobile Equipment Identity of two terminal equipments, International Mobile Station Equipment Identification) is respectively IMEI1 and IMEI2, but the IMSI in these two terminal equipments is identical (for example SIM card is for duplicating fully), two terminal equipments can independently be initiated business and/or position renewal, but operation flow and/or position are more done sign to required user data access with IMSI in the new technological process and are read and write, therefore in data storage procedure, what in fact two terminals were used is same user data of users, as use among the VLR (Visited Location Registor, Visited Location Registor) and the IMSI1 corresponding user data.When more new technological process is stored or is read same user data of users operation flow of initiating when two terminals and/or position, will cause the change of some ephemeral datas in these two flow processing processes unpredictable, influencing each other will appear in handling process, cause handling process unusual, under the serious situation even can cause system in case of system halt.

Embodiment one
Present embodiment provides a kind of communication means, in the method, as shown in Figure 2, in step 21, obtains IMSI International Mobile Subscriber Identity, and determines the communication process that this IMSI International Mobile Subscriber Identity institute counterpart terminal is carried out; In step 22, whether the User Activity sign decision according to predetermined policy, definite communication process and described IMSI International Mobile Subscriber Identity correspondence allows to communicate, described User Activity sign is used to show the communication process that the terminal of current IMSI International Mobile Subscriber Identity correspondence is carried out and whether communicates flow process, perhaps only show the communication process that the terminal of current IMSI International Mobile Subscriber Identity correspondence is carried out, described communication process comprises position more new technological process and service access flow process.Be example with the GSM/UMTS system below.Solve this conflict according to predetermined policy.Below with service access flow process or position more new technological process be the communication means of example explanation present embodiment.
Described conflict is meant the conflict of communication process, and promptly the communication process that carries out of a plurality of terminal of this jack per line conflicts mutually, as position more new technological process and service access flow process, the situation that at a time has two flow processs to exist.This be because, in these two flow processs, need to revise the data among the VLR, when when a certain, being carved with two flow processs, the user data of depositing in user data area need be stored or be read to two operation flows, all be to use the data and the state of same IMSI correspondence this moment owing to two flow processs, will cause that the change of needed data and state clashes in two flow processing processes, cause handling process will occur influencing each other, under the serious situation even can cause system in case of system halt, therefore, at a time can only there be a flow process to exist.
In order to solve above-mentioned conflict, in the initial period of customer service flow process, the User Activity sign is set in VLR database, described User Activity sign can be stored in the User Activity table, and this table comprises two field: IMSI and the User Activity sign corresponding with IMSI.Described User Activity sign is used to show the communication process that the terminal of current I MSI correspondence is carried out and whether communicates flow process, perhaps only show the communication process that the terminal of current I MSI correspondence is carried out, be masked as at 0 o'clock as User Activity, all terminals of this IMSI correspondence do not have activity; User Activity is masked as at 1 o'clock, and a certain terminal of this IMSI correspondence is being carried out more new technological process of position; User Activity is masked as at 2 o'clock, and a certain terminal of this IMSI correspondence is being carried out the service access flow process.Also can adopt alternate manner to show whether to have and carry out activity with the terminal of IMSI.As when in this User Activity table the record of this IMSI correspondence being arranged, show that then the terminal of this IMSI correspondence is movable; And then what judge that this terminal carries out according to the User Activity sign of this IMSI correspondence is any activity, is masked as at 1 o'clock as User Activity, and a certain terminal of this IMSI correspondence is being carried out more new technological process of position; User Activity is masked as at 2 o'clock, and a certain terminal of this IMSI correspondence is being carried out the service access flow process.Like this, go to when reading user data in the VLR database, in VLR, search the User Activity table, handle according to following predetermined policy according to the content of User Activity table then according to IMSI when the User Activity flow process.
If what 1 a plurality of terminals were initiated all is more new technological process of position, the terminal that allows to initiate at first to upgrade the position communicates, and the terminal that the position of coming up after not allowing is upgraded communicates;
If what 2 a plurality of terminals were initiated all is service access flow processs, the terminal that allows to initiate service access at first communicates, and the terminal of the service access of coming up after not allowing communicates;
If 3 in a plurality of terminals, wherein part is initiated more new technological process of position, and another part is initiated the service access flow process, allow to initiate at first the position more the terminal of new technological process carry out subsequent communications, do not allow other terminal to communicate; If more have the service access flow process before the new technological process initiating the position at first, then remove this service access flow process.
According to above-mentioned predetermined policy,, describedly whether allow to communicate specifically to comprise according to predetermined policy, definite communication process and the User Activity sign decision of described IMSI International Mobile Subscriber Identity correspondence if described definite communication process is position more during new technological process:
If the User Activity sign shows there is not communication process, then allow described definite communication process;
If the User Activity sign shows that current communication process is a more new technological process of position, then refuses described definite communication process;
If the User Activity sign shows that current communication process is the service access flow process, then remove this service access flow process, and allow described definite communication process.
When if described definite communication process is the service access flow process, whether described User Activity sign decision according to predetermined policy, definite communication process and described IMSI International Mobile Subscriber Identity correspondence allows to communicate specifically to comprise:
If the User Activity sign shows there is not communication process, then allow described definite communication process;
If it is position more when new technological process or service access flow process that the User Activity sign shows current communication process, then refuse described definite communication process.
To communicate in order understanding better, an example that communicates according to above-mentioned predetermined policy to be described below according to above-mentioned predetermined policy.Suppose: User Activity is masked as at 0 o'clock, and all terminals of this IMSI correspondence do not have activity; User Activity is masked as at 1 o'clock, and a certain terminal of this IMSI correspondence is being carried out more new technological process of position; User Activity is masked as at 2 o'clock, and a certain terminal of this IMSI correspondence is being carried out the service access flow process.And supposition: the communication process that current terminal is asked is a more new technological process of position:
Find that position that current terminal is asked more during new technological process, at first takes out the IMSI User Activity sign corresponding with active user's terminal.When the IMSI User Activity is masked as 0, illustrate that all terminals of this IMSI correspondence do not have activity, the position that allows current terminal is new technological process more; When the IMSI User Activity is masked as 1, illustrate and existing carrying out more new technological process of position that the position of then refusing current terminal is new technological process more with other terminal of IMSI; When the IMSI User Activity is masked as 2, illustrate and existing carrying out the service access flow process with other terminal of IMSI, then remove this service access flow process, and allow more new technological process of position that current terminal asks.
The instant solution of conflicting sometimes has some unusual sensations for user's impression, for example in the User Activity process, because an other activity with IMSI user, and cause current business to be tolled breakdown.
When a plurality of terminals adhere to separately in different VLR, service conflict can not take place directly, but the terminal that the position renewal between two VLR can cause the back to initiate to upgrade the position can not be carried out the position and upgraded.
In above-mentioned communication means, can adopt unlatching authentication or pseudo-TMSI distribution technique to carry out TMSI and distribute, to avoid the TMSI duplicate allocation.Described pseudo-TMSI distribution is meant that each distribution all distributes identical TMSI to give a fixing user, when same user initiates to insert, all distributes identical TMSI to get final product.In the time of actual the realization, the method for pseudo-TMSI can be taked method more flexibly, can allow certain user's TMSI be fixed in the scope, and don't can repeat with the user's of other IMSI TMSI.
