Method, system and equipment for transporting signaling

Abstract

The invention discloses a method, a system and equipment for transporting signaling, belonging to the communication field. The method for transporting singling comprises the following steps: signaling information from a terminal is received by an extensible authentication protocol (eAN) / PCF through a first default route, and the signaling information is sent to an HRDP serving gateway (HSGW) through a second default route; or signaling information from the HSGW is received by the eAN / PCF through the second default route, and the signaling information is sent to the terminal through the first default route; and the bearing separation of the signaling information and data is achieved through the bearing signaling information of the first default route and the second default route. The system for transporting singling comprises user equipment (UE), the eAN / PCF and the HSGW. The sorting of a user plane data packet and signaling in a band can be avoided by using signaling outside the band, the performance of the system for transporting signaling is improved, the processing capacity of the HSGW and the capacity of a serviceable terminal are enhanced, the band width of the surface of the signaling is ensured, the signaling can not lose under the high load of the system for transporting signaling, and the stability and the reliability of the system for transporting signaling are improved. Because the surface of the signaling and the user plane are logically separated, the system for transporting signaling more structurally meets the requirement of the third generation partnership project (3GPP).

Description

technical field [0001] The present invention relates to the communication field, in particular to a signaling transmission method, system and equipment. Background technique [0002] In the traditional 3GPP ((Third Generation Partnership Project, Third Generation Partnership Project)) network, between HRPD (High Rate Packet Data, rate packet data) network terminal and PDSN (Packet Data Serving Node, packet data service node) There is a PPP (point to point protocol, point-to-point transmission protocol) link, whose function is to carry upper-layer data, use the PPP authentication protocol to perform access authentication on the terminal, and use PPP to perform IP address allocation and parameter negotiation. In the evolved 3GPP2 network, eHRPD (enhance-HRPD, evolved HRPD network) no longer uses the PPP protocol. see figure 1 , provides a schematic diagram of an evolved 3GPP network and eHRPD network interworking architecture, wherein, in the eHRPD network, HSGW (HRDP Servin...

Problems solved by technology

[0012] When the inventor realizes the present invention, it is found that the above-mentioned existing HUSP signaling message transmission method has the following disadvantages and deficiencies: since the transmission of the HUSP signaling message is carried by RLP and A10, it is transmitted together with normal user data, For the receiver (whether it is HSGW or UE), taking HSGW as an example, HSGW will check each received data packet to distinguish whether it is a HUSP signaling message, so as to perform corresponding processing

However, in network message intercommunication, compared with user data, signaling messages account for a very small proportion, and signaling messages are transmitted together as data. Since each received data packet needs to be checked to Distinguish whether it is a signaling message or a user data message, which will affect the performance of the HSGW and restrict the processing capacity of the HSGW, thereby reducing the number of users it can serve; especially, when the system load is high, due to the limited signaling bandwidth , will also cause problems such as signaling loss, resulting in a decrease in system stability and reliability
