Problems solved by technology

However, the disadvantage of this solution is that the transmission resources available for unicast services and those available for multicast services are managed separately, which is not conducive to making full use of limited transmission resources
However, the problem with this solution is that when developing unicast services, the required transmission resources need to be requested from the AN through the C-RM. Execution interface, signaling interaction with C-RM is complicated

Embodiment 1

[0059] See Figure 6 , Figure 6 It is a flowchart of AN's management of transmission resources in the first embodiment of the present invention. The process can include the following steps:

[0060] Step 601: The UE initiates a request to the AN to join the multicast group in the AN, and requests to occupy transmission resources.

[0061] In this step 601, the above request may be an IGMP protocol message, and AN obtains the required transmission resources corresponding to the multicast group through pre-configuration; the above request may also be high-level signaling, such as Session Initiation Protocol (SIP) Messages, information about transmission resources required for multicast services can be carried in the Session Description Protocol (SDP, Session Description Protocol) carried by SIP.

[0062] Step 602: After receiving the resource request for occupying transmission resources, the D-RM in the AN can obtain the current usage status of the transmission resources, and perfo...

Embodiment 2

[0070] See Figure 7 , Figure 7 It is a flowchart of C-RM management transmission resources in the second embodiment of the present invention. The process can include the following steps:

[0071] Step 701: The AF sends a resource request to the C-RM to allocate transmission resources for the unicast service.

[0072] Step 702: The C-RM performs resource and admission control on the request of the AF according to the learned current usage status of the transmission resources.

[0073] In practical applications, C-RM can obtain the current usage status of transmission resources in the following two ways:

[0074] One may be that the AN reports the usage status of the transmission resources to the C-RM provided in the embodiment of the present invention. C-RM can learn the size of free resources in the current transmission resources based on the report;

[0075] The other is that the C-RM can be learned according to the usage status of the transmission resources recorded locally, a...

Abstract

The invention provides a resource management method. The method comprises the following steps: after carrying out the resource admission control to a received resource request for occupying a transmitted resource, acquiring the usage condition of the transmitted resource after the resource admission control; according to a predetermined report strategy, reporting the usage condition to a central resource manager, and after the central resource manage obtains the usage condition, carrying out the resource admission control to a received resource request for allocating the transmitted resource according to the usage condition. The invention also provides another resource management method, a resource management system, a resource manager and a resource management device. The resource management methods, the resource management system and the resource management device can solve the potential problem of the transmitted resource conflicts in the multicast / unicast service.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a resource management device, a resource management method and system. Background technique [0002] The increase of broadband users' demands for multimedia and the continuous development of network communication technology have promoted the emergence and development of Internet Protocol TV (IPTV). In IPTV technology, there are two main ways to transmit IPTV media streams, namely on-demand and broadcast. Among them, the on-demand mode has the characteristics of real-time interaction, which can provide users with more personalized choices; the broadcast mode can provide a variety of content for users to choose, which is manifested in that users select different channels and receive different program content. [0003] The realization of on-demand mode adopts unicast technology, and accordingly, unicast services can be carried out through on-demand. The main method of carr...
