Thus, the appearances of the phrases "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
In various embodiments of the present invention, it should be understood that the sequence numbers of the following processes do not mean the order of execution, and the order of execution of the processes should be determined by the functions and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.
In addition, the terms "system" and "network" are often used interchangeably herein.
In the embodiments provided herein, it should be understood that "B corresponding to a" means that B is associated with a from which B may be determined. It should also be understood that determining B from a does not mean determining B from a alone, but may also determine B from a and/or other information.
As shown in fig. 1, a method for obtaining a mobile directory number according to an embodiment of the present invention is applied to a base station, and includes:
Step 101, sending paging information to a terminal; the paging message is used for triggering the terminal to initiate an attachment process, and the paging message carries an International Mobile Subscriber Identity (IMSI) of the terminal;
Specifically, the paging message carries a paging record list (pagingRecordList), and a terminal Identity field (ue-Identity) in the paging record list carries the IMSI of the terminal.
In this step, by sending a paging message carrying the IMSI of the terminal to the terminal, the terminal can initiate an attachment procedure based on the paging message.
Specifically, after receiving a paging message sent by a base station, a terminal sends an attach request to a core network (Evolved Packet Core, EPC), and starts an attach procedure through the attach request; after the attach procedure is completed, the PDN connection procedure can be triggered to complete the default bearer establishment by sending a public data network (Public Data Network, PDN) connection request (PDN Connectivity Request) message to the core network. After the default bearer establishment is completed, the terminal sends an IMS session initiation protocol (Session initialization Protocol, SIP) registration request message to the IMS to initiate an IMS SIP registration procedure.
Step 102, under the condition that an IMS registration success response message sent by an IP multimedia subsystem IMS is received, obtaining a mobile directory number MDN corresponding to the IMSI by analyzing user plane data.
It should be noted that the mobile directory number may also be referred to as a mobile subscriber directory number, which is a personal mobile phone number of the subscriber, and also a phone number that is externally disclosed by the mobile subscriber.
Specifically, the IMS registration success response message is a IMS REGISTER OK 200 message. After receiving IMS REGISTER OK 200 message, the base station can obtain mobile directory number by analyzing data message from S1-U interface, and the mobile directory number is in one-to-one correspondence with IMSI of terminal.
Here, the S1-U interface is a user plane interface, which is a communication interface between the base station and the serving gateway (SERVING GATEWAY, S-GW) for transmitting service data.
In the above embodiment, the base station triggers the terminal to initiate the attachment process by sending the paging message to the terminal, where the paging message carries the international mobile subscriber identity IMSI of the terminal; after the terminal completes the attaching process according to the paging message, triggering the IMS SIP registration process, and further, under the condition that the base station receives the IMS registration success response message sent by the IMS, obtaining the mobile directory number MDN corresponding to the IMSI by analyzing the user plane data. By the embodiment, the base station can conveniently acquire the mobile directory identification code of the terminal.
In an embodiment, the sending the paging message to the terminal includes:
And after the tracking area updating TAU flow of the terminal is determined to be completed and the core network releases the terminal, sending the paging message to the terminal.
In this embodiment, after the tracking area updating TAU procedure of the terminal is completed and the core network releases the terminal, the attachment procedure is initiated by the paging message, so that the terminal and the core network can establish a default bearer for data transmission, continue exchanging user data based on the default bearer, and acquire the mobile directory number MDN of the terminal based on the paging message.
In an embodiment, before sending the paging message to the terminal in step 101, the method further includes:
under the condition that a tracking area updating TAU request message sent by the terminal is received, an identity inquiry request is sent to the terminal, wherein the identity inquiry request is used for acquiring the IMSI of the terminal;
And receiving an identity inquiry response sent by the terminal, wherein the identity inquiry response carries the IMSI of the terminal.
It should be noted that, after the terminal changes the following area (TRACKING AREA, TA) where the terminal is located, the terminal notifies the network of its own new TA through the TAU procedure, so that the network side obtains the location of the terminal.
Optionally, the identity query request carries an identity type cell, where the identity type cell is used to indicate that the identity type of the terminal is the IMSI.
In this embodiment, after receiving the TAU Request (TAU Request) message, the base station constructs an identity query Request (identity Request) message and sends the identity query Request (identity Request) message to the terminal; wherein "IDENTITY TYPE" Information Element (IE) is set to "IMSI". Meanwhile, the base station sends a TAU request message to the core network to perform a TAU flow. After receiving the identity inquiry request message, the terminal sends an identity inquiry response (identity response) to the base station, and after receiving the identity inquiry response, the base station analyzes the IMSI and stores the IMSI to the base station, and the identity inquiry response is not sent to the core network. Thus, the IMSI of the terminal can be obtained based on the TAU update procedure.
As shown in fig. 2, a method for obtaining a mobile directory number according to an embodiment of the present invention is applied to a terminal, and includes:
Step 201, receiving paging message sent by base station; the paging message is used for triggering the terminal to initiate an attachment process, and the paging message carries an International Mobile Subscriber Identity (IMSI) of the terminal;
Specifically, the paging message carries a paging record list (pagingRecordList), and a terminal Identity field (ue-Identity) in the paging record list carries the IMSI of the terminal.
Step 202, after completing the attachment flow according to the paging message, an IMS session initiation protocol SIP registration request message is sent to the IMS.
Specifically, after receiving a paging message sent by a base station, a terminal sends an attach request to a core network (Evolved Packet Core, EPC), and starts an attach procedure through the attach request; after the attach procedure is completed, the PDN connection procedure can be triggered to complete the default bearer establishment by sending a public data network (Public Data Network, PDN) connection request (PDN Connectivity Request) message to the core network. After the default bearer establishment is completed, the terminal sends an IMS session initiation protocol (Session initialization Protocol, SIP) registration request message to the IMS to initiate an IMS SIP registration procedure. After the IMS SIP registration is completed, the IMS sends an IMS registration success response message to the base station.
Under the condition that the base station receives an IMS registration success response message sent by an IP multimedia subsystem IMS, the base station obtains a mobile directory number MDN corresponding to the IMSI of the terminal by analyzing user plane data.
In the above embodiment, after receiving the paging message sent by the base station, the terminal triggers the terminal to initiate an attachment flow through the paging message, where the paging message carries the international mobile subscriber identity IMSI of the terminal; after the terminal completes the attaching process according to the paging message, triggering the IMS SIP registration process, and further, under the condition that the base station receives the IMS registration success response message sent by the IMS, obtaining the mobile directory number MDN corresponding to the IMSI by analyzing the user plane data.
