Problems solved by technology

[0009] In addition, an MGW or MSC Server may run in different network environments. In the ATM network or in the IP network, it is necessary to provide different types of interfaces for upward transmission, because different networks require different software modules to implement, resulting in different software version of
The inconsistency of this type of interface brings inconvenience to the design and use of the product

Embodiment Construction

[0041] The signaling adaptation method of the present invention adapts a link layer interface to a network layer interface through link management, thereby providing a unified signaling transmission interface for H.248.

[0042] In the case where two types of interfaces exist at the same time, although an entity may use different interfaces for other entities, the interface between two certain entities on the network is fixed, for example, MSC Server A and It is impossible to use H.248 / MTP3B / SSCF / SSCOP / AAL5 / ATM and H.248 / SCTP / IP transmission between MGW B, that is to say, in a certain entity, H.248 transmission signaling , as long as its purpose is determined, the network interface type is determined.

[0043] Figure 4 It shows a logical block diagram of the signaling adaptation system implementing the method of the present invention. As shown in the figure, the adaptation system of the present invention includes three functional modules: link management, office management and...

Abstract

The invention discloses a signaling transmission adaptation method of the H.248 protocol of the Mc interface, which adapts the link layer interface to the network layer interface through the management link, thereby providing a unified signaling for the H.248 entity The transmission interface, where the link management manages the status of the link and reports it to the office management; the office management calculates the outgoing information based on the link information and reports it to the H.248 entity, or forwards the office information of the network layer interface to the H.248, and Allocate links for outbound signaling data to realize load sharing and link failure backup; the data processing performs data sending and receiving, and the adaptation method of the present invention shields the details of lower layer signaling transmission from the H.248 protocol, which is H. The .248 entity provides a unified signaling transmission interface, and can meet the requirements of load sharing, fault backup and orderly transmission of messages.

Description

technical field [0001] The present invention relates to the signaling transmission of the bearer control separation network, in particular to the signaling transmission of Mc interface in WCDMA / CDMA2000 / TD system defined by 3GPP / 3GPP organization and H.248 protocol in NGN. Background technique [0002] The H.248 protocol is adopted by organizations such as 3GPP / 3GPP2 as the protocol standard of the Mc interface, and is mainly used for gateway control and bearer establishment control between the MSC server (MSCServer) and the media gateway (MGW). [0003] As an application protocol, the H.248 protocol has no restrictions on the transmission method. The transmission modes of H.248 signaling messages in the Mc interface are specified in 3GPP TS-29.232 as follows: [0004] For pure IP connections, H.248 / SCTP / IP should be used. In addition, in order to provide efficient use of SCTP coupling, an M3UA layer can also be added on top of SCTP to allow flexible implementation of gate...
