Description

 Calling method, system, terminal, dialing sequence server and mapping server

Technical field

 The present invention relates to the field of communications, and in particular, to a calling method, system, terminal, dialing sequence server, and mapping server. Background technique

 With the development and popularization of IP (Internet Protocol) technology, voice communication and video communication based on IP technology have also been widely used (such as video telephony, video conferencing, instant messaging (IM) chat, etc. ). Compared to traditional Public Switched Telephone Network (PSTN) telephone calls, IP technology-based calls have the advantage of reducing system complexity, reducing costs, and making full use of network resources. Compared with the traditional PSTN call using the telephone number method, the IP call is paged based on the Uniform Resource Identifier (URI) or IP address, and the user is very inconvenient to use (the user cannot input a URI like the Internet). To make a call), in addition, calls based on dialing sequences (eg, phone number) have been deeply rooted in the public (eg, 911 emergency calls in the US, 110 alarm calls in China, etc.) and PSTN, Global System for Mobile (Global System for Mobile) Traditional networks such as Communications, GSM) are still in use, and need to be converted between traditional dialing methods and new URI-based routing.

 To solve these problems, related technologies use to map phone numbers to URIs (for example

ENUM[RFC6116]), when the user makes a call through IP, the telephone number can be input like a traditional telephone. The server maps the telephone number to a URI and then routes it to the receiving end (if the receiving end is a traditional network access, then) Using the inverse mapping process), but when the user does not know the receiving phone number, especially in some special cases, this solution will not work.

Example

 This application example describes the following scenario: A foreign (not US) user A, who has an IP phone terminal (such as a mobile phone). The process of making an emergency call (with international roaming function) when it is in the United States and in China is described below.

 The process of initiating an emergency call when it roams to the United States includes the following steps.

 D1: User A mobile phone is registered to the current network (for example, a network of a US carrier).

D2: The current network obtains the local location information (the location where User A is located), and sends the local frequently used dialing sequence to User A's mobile phone.

 Here the carrier's network acts as a dial-up sequence server and as a function to detect the current location of the user terminal.

 D3: The phone automatically caches the location information and/or dialing sequence and automatically binds the dialing sequence. For example, the dialing sequence returned in the United States is 911 (assuming User A does not know that the US emergency phone is 911). User A's phone automatically binds 911 to Speed Dial 1. This is what User A says is transparent and he has not done anything.

 D4: User A initiates a call.

For example, User A encounters an emergency, and he can quickly dial 911 by pressing the number key 1. D5: User A's mobile phone sends the dialing sequence to the mapping server (for example, the carrier's network).

D6: The mapping server sends the URI corresponding to the dialing sequence (911) to the mobile phone.

 When the URI is obtained, the phone can cache the URI so that it can be used the next time the location has not changed.

 D7: The mobile phone initiates a Session Initiation Protocol (SIP) call INVITE request to the receiving end of the URI indication (for example, a Public Safety Answering Point (PSAP)), and the request carries the URI and the location information.

 D8: The receiving end receives the INVITE request and responds to the sending end with a 200 OK response.

 D9: Call setup.

 After the call is established, user A can make a call with the receiving end. The location information carried in the call request is advantageous for the receiving end to locate the location where the user A is located (in some special cases, the user may not know the location of the user), and is convenient to assign. rescue team.

 When User A roams to China later, the emergency call process includes the following steps.

 E1: User A mobile phone is registered to the current network (for example, China Mobile's network).

 E2: The current network knows the local (China) location information, and sends the local common dialing sequence (such as Table 1) to User A's mobile phone.

 E3: The phone automatically updates the location information and/or dialing sequence in the cache and automatically binds the dialing sequence.

 For example, bind 110 to the number key 1 . When a user encounters an emergency, they can get alert help by speed dialing as in the US.

 When the user initiates a call, the flow is as described in the above D4-D9, and will not be described again.

 The call flow when the user moves from one place in China to another (such as from Shanghai to Hangzhou) includes the following steps.

 F1: Switch between base stations of China Mobile network, and detect the change of user's mobile phone position during the handover process.

 F2: Compare the new location information with the location information in the cache and find that it is still in China and does not update the dialing sequence in the cache.

The flow when the user initiates a call is as described above in the case of D1-D9, and will not be described again. One of ordinary skill in the art will appreciate that all or a portion of the above steps may be accomplished by a program that instructs the associated hardware, such as a read-only memory, a magnetic disk, or an optical disk.
