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] Fig. 4 shows a logic 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 data pr...

Abstract

The invention discloses an Mc interface H.248 protocol signaling transmission adapting method, by managing links, adapting a link layer interface into a network layer interface, accordingly providing a united signaling transmission interface for a H.248 protocol entity, where link management manages link states and reports to bureau management; the bureau management calculates bureau information according to link information and report to the H.248 protocol entity or transmits bureau information of network layer to the H.248 protocol entity and allocates a link to the outgoing signaling, so as to implement load sharing and link failure backuping; the data processing includes data transmission and reception. The invention provides a united signaling transmission interface for a H.248 protocol entity and can meet the requirements for load sharing, failure backuping and information orderly transmission.

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...
