Problems solved by technology

[0028] In the original DOCSIS network, a CMTS can support tens of thousands of users at most, so only a few hundred or less CMTS devices are needed to cover 10 million users; while in the C-DOCSIS network, because the CMTS devices are moved down, A CMTS device generally only supports a few hundred or less users, so a large number of CMTS / CMC devices are required in the C-DOCSIS network, and the devices that implement the PolicyServer function are generally only Support a small number of CMTS devices (such as 256 CMTS devices), it is difficult to support a large number of CMTS / CMC devices in the C-DOCSIS network, and the resource reservation method applicable in the original DOCSIS network is not well applicable into the C-DOCSIS network

Embodiment 1

[0060] refer to Figure 4 , the present invention provides a resource reservation method, including:

[0061] 101. The converging device receives a first resource reservation request message based on a first interface format from a PS.

[0062] In this embodiment, the above-mentioned first interface format may be pkt-mm-2.

[0063] 102. The convergence device converts the first resource reservation request message into a second resource reservation message based on the second interface format;

[0064] In this embodiment, the above-mentioned second interface format may be pkt-mm-2'.

[0065] 103. The convergence device sends the second resource reservation message to the modem system, so that the modem system performs resource reservation according to the second resource reservation request message.

[0066] In this embodiment, the second resource reservation request message contains the resource reservation request, and the modem system can parse the resource reservation r...

Embodiment 2

[0070] refer to Figure 5 , the present invention provides a resource reservation method, including:

[0071] 201. The AM receives a request message for resource reservation for a session from a P-CSCF.

[0072] When the UE wants to establish a session and initiates a session request to the P-CSCF through the Gm interface, the P-CSCF will notify the AM to reserve resources for the above session through the Rx interface;

[0073] When the UE wants to end the session and initiates a session termination request to the P-CSCF through the Gm interface, the P-CSCF will notify the AM through the Rx interface to release the resources occupied by the above session.

[0074] After receiving the request message, the AM will analyze the request message, determine the QoS resource required by the session or the occupied QoS resource, and generate a third resource reservation request message.

[0075] 202. The AM sends a third resource reservation request message to the PS through the pkt...

Embodiment 3

[0104] refer to Figure 6 and Figure 7 , the present invention provides a resource reservation method, including:

[0105] 301. The AM receives a request message for resource reservation for a session from a P-CSCF.

[0106] When the UE wants to establish a session and initiates a session establishment request to the P-CSCF through the Gm interface, the P-CSCF will notify the AM to reserve resources for the above session through the Rx interface;

[0107] After receiving the request message, the AM parses the request message, determines the QoS resource required by the session or the occupied QoS resource, and generates a third resource reservation request message.

[0108] 302. The above-mentioned AM sends a third resource reservation request message (Gate-Set) to the PS through the pkt-mm-3 interface, and the above-mentioned third resource reservation request message (Gate-Set) includes information corresponding to the above-mentioned session to be established. Resource ...

Abstract

The embodiment of the present invention relates to the technical field of communication, and discloses a resource reservation method, system and convergence device. Wherein, the method includes: the converging device receives the first resource reservation request message based on the first interface format from the policy server PS; the converging device converts the first resource reservation request message into a resource reservation request message based on the second interface format A second resource reservation request message; the converging device sends the second resource reservation request message based on the second interface format to the modem system, so that the modem system can reserve according to the second resource Leave a request message for resource reservation. The resource reservation method, system and converging device provided by the present invention enable the converging device to act as a dynamic QoS agent between the PS and the CMTS, and the number of converging devices in the network is relatively smaller than that of the CMTS device. PS only needs to manage a small number of aggregation devices, which facilitates end-to-end control.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a resource reservation method, system and convergence device. Background technique [0002] DOCSIS (Data Over Cable Service Interface Specification, cable transmission data service interface specification) is a communication standard that can transmit data at high speed in the existing Cable TV network system, such as figure 1 As shown, in the network where DOCSIS technology is applied, it mainly includes CMTS (Cable Modem Terminal Systems, cable modem termination system) and CM (Cable Modem, cable modem) two devices, among which CMTS is a large device connected to the WAN, It can support more than tens of thousands of users. The CM is located on the remote user side and connected to the home network. The CMTS and CM are connected through the HFC (Hybrid Fiber-Coaxial, hybrid fiber-coaxial cable network) network. The DOCSIS standard mainly supports the transmissio...
