Abstract
The invention discloses a method for implementing single-number double-card in a mobile communication system, such as in the GSM system. From the angle of the user service property, the invention divides the SIM card into two categories: a full-service card and a data service card. The invention defines different roaming properties for the full-service card and the data service card. When the HLR processes the MAP message, it selects subsequent executing contents according to the different roaming properties of a same MSISDN, thereby solving the addressing confusion problem brought by that a plurality of SIM cards share a same MSISDN. The implementing principle of the present invention can be applied to the CDMA system. Compared to the prior art, the present invention does not introduce new nodes in the GSM network, does not destroy the system architecture and interface protocol criterion of the GSM system, and realize that an MSISDN corresponds to a plurality of SIM cards in the GSM system and an MSISDN corresponds to a plurality of UIM cards in the CDMA system, in a software mode.
Description
Technical Field
The invention relates to the technical field of mobile communication, in particular to how to realize that a plurality of SIM cards share the same MSISDN in the field of a GSM system and how to realize that a plurality of UIM cards share the same MSISDN in the field of a CDMA system.
Background
In the existing GSM system, MSISDN of a user and SIM card are in one-to-one correspondence, and the SIM card and IMSI of the user are also in one-to-one correspondence, if the user needs to have a voice call and use a notebook computer to access the internet at the same time, two SIM cards, i.e. two MSISDNs, are needed, which is not only convenient for the user to manage his own number, but also wastes MSISDN number resources of the operator. The same problem exists with existing CDMA systems. In order to realize that one MSISDN can correspond to multiple SIM cards, the key is to realize that the HLR can address multiple SIM cards according to the same MSISDN. The most similar public technology of the scheme of the invention adopts a mode of introducing a MULTI SIM platform, wherein the platform is a node in a NO.7 signaling system and is responsible for transferring MAP signaling between MSC and HLR. The concept of 'primary IMSI' is introduced into the MULTI SIM platform, the IMSI of the called user which is currently connected is defined as the 'primary IMSI' which is uniquely corresponding to the MSISDN of the called user, and the HLR only adopts the 'primary IMSI' to carry out subsequent connection, thereby shielding different IMSIs of a plurality of SIM cards sharing the same MSISDN. The method introduces a MULTI SIM platform and defines a main IMSI to avoid the problem of addressing confusion caused by the fact that a plurality of SIM cards share the same MSISDN.
The prior art has the following disadvantages: in the prior art, a new node (MULTI SIM platform) is introduced into a GSM system, and interface specifications of the GSM system and message specifications of MAP signaling need to be redefined, which has a large impact on the system structure of the GSM network. The existing GSM system or CDMA system network requires significant changes if such a scheme is adopted.
Disclosure of Invention
Aiming at the defects of the prior art, the technical problems to be solved by the invention are as follows:
taking GSM system as an example, the invention divides the SIM cards of users into two types from the perspective of the service attributes of the users. The first type: a certain SIM card with corresponding MSISDN of a and having a full service function (such as voice, short message, GPRS, etc.) provided by the network for the user is called a full service card; the second type: the corresponding MSISDN is a, but multiple SIM cards with only data service functions (such as GPRS functions), which are called data service cards. The HLR selects the subsequent execution content according to the different roaming attributes of the same MSISDN when processing the MAP message for the roaming attributes of the full service card and the data service card, thereby solving the problem of addressing confusion caused by the sharing of the same MSISDN by a plurality of SIM cards. The implementation principle of the present invention can also be applied to a CDMA system. Compared with the prior art, the invention does not introduce a new node into a GSM network, does not damage the system structure and the interface protocol specification of the GSM system, and realizes that one MSISDN corresponds to a plurality of SIM cards in the GSM system and one MSISDN corresponds to a plurality of UIM cards in the CDMA system in a software mode.
The technical scheme of the invention is as follows: a method for realizing one number multiple cards in mobile communication system divides user service attribute into full service card and data service card, the full service card and data service card sharing the same MSISDN define different roaming attribute, HLP selects the following execution content by different roaming attribute of the same MSISDN when processing message.
The above method for implementing one number with multiple cards in a mobile communication system is further characterized in that:
in a GSM system, a certain SIM card sharing the same MSISDN is provided with a full service function provided by a GSM network for a user, and is called a full service card, and the rest multiple SIM cards sharing the same MSISDN only have a data function and are called data service cards; the roaming attribute of the full service card is defined as the BOTH MSC AND SGSN, and the roaming attribute of the data service card is defined as the ONLY SGSN.
In a GSM system, when the HLR processes the position update initiated by a full-service card, the HLR allows the position update of the HLR on an MSC and an SGSN; when the HLR processes the location update initiated by the data service card, the HLR only allows the location update on the SGSN and rejects the location update on the MSC.
In the GSM system, after receiving the SRI message, the HLR only sends a PRN message to the MSC where the user with the roaming attribute of BOTH MSC AND SGSN is located, so that the call is naturally connected to the full service card of the called user and is not connected to the data service card.
In the GSM system, after receiving the SRI for SMS message, the HLR only sends the PRN message to the MSC where the user with the roaming attribute of BOTH MSC AND SGSN is located, so that the short message is naturally connected to the full service card of the called user and is not connected to the data service card.
In a CDMA system, a certain UIM card sharing the same MSISDN is provided with a full service function provided by a CDMA network for a user, and is called a full service card, and other multiple UIM cards sharing the same MSISDN are only provided with a data function and are called data service cards; the roaming attribute of the full service card is defined as BOTH MSC AND AAA, and the roaming attribute of the data service card is defined as ONLY AAA.
In CDMA system, when HLR processes location update initiated by full service card, it allows its location update on MSC and AAA; when the HLR processes the location update initiated by the data service card, the HLR only allows the location update on the AAA and rejects the location update on the MSC.
In the CDMA system, after receiving the SRI message, the HLR only sends a PRN message to the MSC where the user with the roaming attribute of BOTH MSC AND AAA is located, so that the call is naturally connected to the full service card of the called user and is not connected to the data service card.
In the CDMA system, after receiving SRI for SMS message, HLR sends PRN message only to MSC where the user with roaming attribute BOTH MSC AND AAA is located, so the short message is naturally connected to the full service card of the called user, and will not be connected to the data service card.
The invention has the beneficial effects that:
take GSM system as an example for explanation. From the perspective of user service attributes, the present invention defines a certain SIM card sharing the same MSISDN as a full service card, wherein the SIM card is provided with the full service functions (such as voice, short message, GPRS, etc.) provided by the GSM network for the user, and the other SIM cards sharing the same MSISDN as a data function (such as GPRS) are defined as data service cards. The invention defines different roaming attributes for the full service card and the data service card, so that the HLR selects the subsequent execution content according to the different roaming attributes of the same MSISDN when processing the MAP message. Compared with the prior art, the invention does not introduce a new node into the core network of the existing mobile communication system, does not damage the system structure and the interface protocol specification of the mobile communication system, realizes that one MSISDN corresponds to a plurality of SIM cards in a GSM system and realizes that one MSISDN corresponds to a plurality of UIM cards in a CDMA system by a software mode, is easy to realize and has lower cost.
After the invention is used for business, the user can conveniently manage the mobile subscriber number of the user, the user can apply for one full service card to be used for services such as conversation, short message, data (such as GPRS or CDMA1X) and the like, and can also apply for a plurality of data service cards to be specially used for internet browsing and downloading, the full service card and the data service cards can simultaneously complete the connection of respective services, and share one MSISDN, the accounting records of the user are all related to the MSISDN, and the trouble of managing a plurality of accounts by the user is avoided. In addition, the invention also saves the increasingly tense MSISDN number resource of the operator.

Detailed Description
The following describes the technical solution of the present invention in detail by taking GSM as an example, and the implementation principle of the present invention in the CDMA system is completely consistent with that in the GSM system.
The invention divides the SIM card of the user into two types from the perspective of the service attribute of the user. The first type: a certain SIM card with corresponding MSISDN of a and having a full service function (such as voice, short message, GPRS, etc.) provided by the network for the user is called a full service card; the second type: the corresponding MSISDN is a, but multiple SIM cards with only data service functions (such as GPRS functions), which are called data service cards. The roaming attribute of the full service card is defined as the BOTH MSC ANDSGSN, and the roaming attribute of the data service card is defined as the ONLY SGSN. Because the data service card ONLY needs to be registered on the SGSN to realize all data services, defining the roaming attribute of the data service card as ONLY SGSN does not affect the use of the data service card. Fig. 1 shows a schematic diagram of attribute definition of multiple SIM cards sharing the same MSISDN.
When the full service card initiates location update, HLR judges its roaming attribute as BOTH MSC ANDSGSN, and allows it to complete location update according to normal location update flow. When the data service card initiates location update, the HLR judges that the roaming attribute is ONLY SGSN, and then the HLR rejects the location update of the HLR at the MSC and ONLY allows the location update of the HLR at the SGSN. The specific flow is shown in figure 2.
When a user calls a user signing the one-number-multiple-card service, a calling end office sends an SRI message to a home HLR of a called user, the HLR retrieves according to a user MSISDN carried in the SRI message, at the moment, because the user signs the one-number-multiple-card service, the HLR retrieves a plurality of IMSIs corresponding to the MSISDN of the called user, user data of a full-service card and user data of a data service card, and the HLR only processes the IMSI with a roaming attribute of BOTH MSC ANDSGSN, namely only sends a PRN message to an MSC corresponding to the IMSI of the full-service card, so that the call is naturally connected to the full-service card of the called user and cannot be connected to the data service card. The specific flow is shown in FIG. 3.
When a user sends a short message to a user signing the one-number-multiple-card service, a calling end office sends an SRIfor SMS message to an HLR of the home of a called user, the HLR retrieves according to a user MSISDN carried in the SRIfor SMS message, at the moment, because the user signs the one-number-multiple-card service, the HLR retrieves a plurality of IMSIs corresponding to the MSISDN of the called user, user data of a full-service card and user data of a data service card, and at the moment, the HLR only processes the IMSI with a roaming attribute of BOTH MSC AND SGSN, namely, only sends a PRN message to an MSC corresponding to the IMSI of the full-service card, so that the short message is naturally connected to the full-service card of the called user and cannot be connected to the data service card. The specific flow is shown in figure 4.
The mobile phone adopts IMSI to interact with the network when performing GPRS registration, position updating and PDP activation, and the full service card and the multiple data cards of the invention have independent IMSI, so the GPRS services of the full service card and the multiple data cards can not be influenced and can be initiated simultaneously.
In the CDMA system, the UIM card may be divided into a full service card and a data card according to the above division principle, where the roaming attribute of the full service card is defined as BOTH MSC AND AAA, and the roaming attribute of the data service card is defined as ONLY AAA. When HLR processes MAP message, similar to GSM system, it can still select the following execution content according to different roaming attributes of full service card and data service card, thus realizing that multiple UIM cards share the same MSISDN.
The invention follows MAP protocol specification, taking GSM system as an example, the invention uses different roaming attributes (BOTH MSCAND SGSN, ONLY SGSN) to distinguish a plurality of SIM cards (namely a plurality of IMSIs) sharing the same MSISDN, and in the processing logic of the MAP message by HLR, the received SRI message and SRI for SMS message are connected to the IMSI with the roaming attribute of BOTH MSC AND SGSN. The problem of addressing confusion caused by the fact that a plurality of SIM cards share the same MSISDN is solved, and the HLR can address a plurality of SIM cards according to the same MSISDN. The invention has the advantages of completely consistent realization principle in the CDMA system and the GSM system, clear and strict logic, accordance with the MAP protocol specification and feasibility.
Although the present invention has been described by way of examples, the examples are not intended to limit the present invention. Various changes and modifications within the spirit of the present invention may be made by those skilled in the art, and the scope of the present invention should be defined by the appended claims.
