Embodiment 1

[0045] Referring to Fig. 1, the mapping relationship of IMSI or user terminal IP address and MDN is stored in authorization, verification, and billing center (AAA) network element, and the method for MMSC to obtain corresponding mobile phone terminal MDN is as follows:

[0046] Steps 101 to 102: the mobile terminal initiates a multimedia message (MMS) request message, which arrives at the PDSN through the wireless core network, and after being authenticated by the PDSN, the PDSN sends a billing request message to the mobile terminal to the AAA;

[0047] Wherein, the charging request message includes the IMSI or IP address of the mobile terminal, MMSC information, and corresponding service information;

[0048] Step 103: AAA is configured as Radius Proxy mode. After AAA receives the charging request message from PDSN, it obtains the MDN of the corresponding mobile terminal according to the mapping relationship between the IMSI, IP address, and MDN stored locally; AAA puts the ob...

Embodiment 2

[0056] Referring to Figure 2, the mapping relationship between IMSI, user terminal IP address, and MDN is preset in the AAA network element, and the method for MMSC to obtain the corresponding mobile terminal MDN is as follows:

[0057] Steps 201 to 202: the mobile terminal initiates an MMS request message, which reaches the PDSN through the wireless core network, and after being authenticated by the PDSN, the PDSN sends a billing request message for the mobile terminal to the AAA;

[0058] Wherein, the charging request message includes the IMSI or IP address of the mobile terminal, MMSC information, and corresponding service information;

[0059] Step 203: After receiving the charging request message from the PDSN, AAA obtains the MDN of the corresponding mobile terminal according to the mapping relationship between the IMSI or IP address of the mobile terminal stored locally and the MDN, and then puts the obtained MDN into the response message Send back to PDSN;

Embodiment 3

[0064] Referring to Figure 3, the mapping relationship between IMSI, user terminal IP address, and MDN is preset in the AAA network element, and the method for the MMSC to obtain the MDN of the corresponding mobile terminal is as follows:

[0065] Steps 301 to 302: The mobile terminal initiates an MMS request message, which reaches the PDSN through the wireless core network, and after being authenticated by the PDSN, the PDSN sends the MMS request message to the MMSC;

[0066] Wherein, the data business service center in this embodiment is MMSC, and may also be other data business service centers that require MDN information, wireless application protocol gateways (WAPGW) that require MDN information, wireless integrated service gateways (WISG), etc. in actual networks. The network element does not affect the realization of the present invention;

[0067] Step 303: AAA is configured as a Radius Proxy mode, and the MMSC sends a request to obtain an MDN to the AAA through the Ra...

Abstract

The invention relates to a method for using data service center to obtain the user terminal identification information, and a relative system, wherein said method comprises that: setting IMSI, user terminal IP address, and projection with MDN on the system network unit; the center via communication with PDSN and system network unit. And the system comprises PDSN, network unit, and data service center. With said invention, user terminal can use data service center to identify the user terminal, without special order.

Description

technical field [0001] The invention relates to the field of authentication in communication technology, in particular to a method and system for realizing authentication information of a user terminal obtained by a data business service center. Background technique [0002] In the Code Division Multiple Access (CDMA) system, since the mapping relationship between the International Mobile Subscriber Identity (IMSI) or the user terminal Internet Protocol (IP) address and the Mobile Subscriber Directory Number (MDN) has not been realized, the MDN is exactly It is the authentication information needed by the data service center to authenticate the user terminal. Therefore, all data services have the problem that the data service center cannot obtain the user terminal authentication information, which will eventually lead to the data service center being unable to realize the authentication of the user terminal. Terminal authentication. [0003] Taking the MMS service as an exa...
