Embodiment 1

[0057] Embodiment 1 of the present invention provides a method for downloading resources. The steps of the method are as follows: image 3 shown, including:

[0058] Step 101, the application server receives a connection establishment request sent by a resource requesting terminal.

[0059] In order to reduce the signaling pressure on IMS core network elements and reduce the occupation of air interface (air interface) resources, when a resource requesting terminal needs to download resources from multiple resource providing terminals, it can send a connection establishment request, which carries the Address information of a plurality of resource providing terminals, the address information may be obtained by the resource request terminal from a resource list that can provide download resources obtained from a resource directory index server (Tracker) in the IMS system.

[0060] Step 102, the application server sends connection establishment requests to corresponding resource ...

Embodiment 2

[0078] Embodiment 2 of the present invention provides a resource download method. In this embodiment, UE1 performs signaling interaction with the application server through S-CSCF1, and UE2 and UE3 also perform signaling interaction with the application server through S-CSCF2 and S-CSCF3 respectively. command interaction, the steps of this method are as follows Figure 4 shown, including:

[0079] Step 201, UE1 sends a connection establishment request to S-CSCF1.

[0080] Step 202, S-CSCF1 forwards the connection establishment request to the application server.

[0081] Step 203, the application server copies the received one connection establishment request into two, and sends them to S-CSCF2 and S-CSCF3 respectively.

[0082] Step 204, S-CSCF2 and S-CSCF3 send the received connection establishment request to UE2 and UE3 respectively.

[0083] Step 205, UE2 and UE3 return connection response messages to S-CSCF2 and S-CSCF3 respectively.

[0084] Step 206, S-CSCF2 and S-CS...

Embodiment 3

[0100] Since the process of establishing a connection between any one of multiple resource requesting terminals and a resource providing terminal is the same as the process of establishing a connection in steps 101 to 103 in Embodiment 1, in this embodiment, for example, multiple resource requesting terminals and resource Provide a detailed description of the bitmap information exchange process between terminals.

[0101] Such as Figure 6 As shown, it is a schematic flowchart of a resource downloading method provided in Embodiment 3 of the present invention, and the method specifically includes the following steps:

[0102] Step 301, the application server combines the received bitmap information sent by multiple resource requesting terminals into one piece of bitmap information and sends it to the resource providing terminal.

[0103] The application server may combine the messages carrying the bitmap information sent by each resource requesting terminal within the set time...

Abstract

The invention provides a resource downloading method and system and an application server. The resource downloading method concretely comprises the following steps of: copying bitmap information sent by a resource downloading terminal into multiple copies and distributing multiple copies to each resource supplying terminal when one resource downloading terminal requests downloading to multiple resource supplying terminals, and merging multiple bitmap information returned by each resource supplying terminal into one and returning the merged bitmap information to the resource downloading terminal, or merging multiple bitmap information of multiple resource downloading terminals into one and sending the merged bitmap information to the resource downloading terminal when multiple resource downloading terminals request downloading to one resource supplying terminal, so that only one signaling is received by one resource downloading terminal or sent by one resource supplying terminal, thus quantity of signaling between the resource downloading terminal or the resource supplying terminal and an IMS (IP Multimedia Subsystem) core network element is greatly reduced, signaling pressure of the IMS core network element is reduced, and occupation to wireless network air interface resource is reduced.

Description

technical field [0001] The invention relates to the communication field, in particular to a resource downloading method, system and application server. Background technique [0002] IMS (IP Multimedia Subsystem) is an IP multimedia system, a brand-new multimedia service form, which can meet the more novel and more diversified multimedia service requirements of end users. At present, IMS is considered as the core technology of the next generation network, and it is an important way to solve problems such as the integration of mobile and fixed networks, as well as the triple integration of voice, data, and video. [0003] The IMS distributed content distribution system refers to the use of distributed technology to provide content distribution services in IMS, and the sharing of resources and information is realized through direct interaction between content storage nodes (terminals) in the system. Its system architecture is as follows: figure 1 Shown: [0004] The IMS distr...
