Embodiment 1

[0044] Embodiment one: figure 1 Describes a situation where the user shuts down the computer. Its process includes:

[0045] 1) The calling user A calls the called user B;

[0046] 2) When fetching MSRN, VLR(B) finds that user B has turned off the phone;

[0047] 3) HLR finds that B needs to understand the unconnected incoming call, and the failure response returned to SRI includes a request to send a short message; the system judges whether user B needs to understand the unconnected incoming call by judging the following four items: A ) Whether user B has enabled the notification function; B) Whether user B has enabled the caller ID function; C) Whether the incoming call number is available; D) Whether the incoming call number can be passed. The principle is: Notifications cannot be missed, but unnecessary notifications should also be avoided, as explained below.

[0048] 4) call release;

[0049] 5) MSC(A) sends a short message to user B, informing him that A has called...

Embodiment 2

[0050] Embodiment two: figure 2 Describes the pre-paging situation where the user is not in the service area. Its process is:

[0051] 1) The calling user A calls the called user B;

[0052] 2) When obtaining MSRN, it is necessary to initiate pre-paging;

[0053] 3) If the paging fails, a response to failure to obtain MSRN is returned;

[0054] 4) HLR discovers that B needs to understand the incoming call that is not connected, and includes sending a short message request in the failure response returned to SRI;

[0055] 5) call release;

[0056] 6) MSC(A) sends a short message to user B, informing him that A has called.

Embodiment 3

[0057] Embodiment three: image 3 Describes the normal paging situation where the called user is not in the service area. Its process is:

[0058] 1) The calling user A calls the called user B;

[0059] 2) In the process of obtaining MSRN, do not initiate paging and return to MSRN;

[0060]3) After the initial address message IAI in the call connection message arrives, paging is initiated, but the paging fails;

[0061] 4) call release;

[0062] 5) MSC (B) discovers that B needs to know about the unconnected incoming call, and sends a short message to user B, informing him that A has called;

Abstract

This invention discloses a method for reporting unsuccessful calling-in connection in mobile network characterizing that when a call of a calling user to a called user can not be successfully contected, the mobile exchange center sends a short message to the called user containing at least number of the calling user. Sine the above scheme is applied, short message is used to transfer calling user information, who can understand situatino of unifnished incoming conveniently, sponsored by network.

Description

Technical field: [0001] The invention relates to a method for notifying an incoming call not connected successfully in a mobile network. Background technique: [0002] In a communication system, especially in a wireless communication network, due to various reasons such as the user moves out of the service area, the user is busy, and the user has turned off the phone, the called user often cannot be connected. The called user may miss some important information because he cannot get the information of the calling party, and needs the network to notify him of who and when he wants to communicate with him. [0003] In order to know information about some unknown calls, some GSM specifications in the prior art can provide help. The following lists several supplementary services in the GSM protocol, and describes the application of these protocols for the called user to understand related information: [0004] 1. Call Forwarding [0005] There are four types of forwarding: fo...
