Abstract
In the invention, radio network controller (RNC) sends message of load control protocol and message of call control protocol to media gateway (MGW). MGW own processes the message of load control protocol, and MGW transmits the received message of call control protocol to a mobile switching center server (MSC) to process. MSC_Server configures MGW as a signaling transit point (STP) to reach RNC. Thus, message of call control protocol is sent to MGW first, and then is transmitted to RNC. The invention provides a method for RNC of R99 to switch in WCDMA R4 network seamless so as to utilize current network equipment fully. The invention makes current network equipment upgrade to R4 network smoothly so as to save investment.
Description
Technical field
The present invention relates to moving communicating field, relate in particular to a kind of in Wideband Code Division Multiple Access (WCDMA) (WCDMA) mobile network the method for access of radio network controller.
Background technology
In the WCDMA of 3G (Third Generation) Moblie network version 4 (Wideband Code Division Multiple Access (WCDMA)) standard (3G R4), introduced separation gateway structure, mobile services switching centre (MSC:Mobile-services Switching Centre) in the WCDMA standard (3G R99) of 99 years versions is separated into media gateway (MGW:Media Gateway) and mobile services switching centre server (MSC_Server), carrying terminates in MGW, MSC_Server calls out control, realized calling out separating of control and carrying control, MSC_Server is by MGCP (H.248) control MGW, MGW and MSC_Server need signaling point code to transmit asynchronous transfer mode adaptation layer two bearer control protocol (Q.AAL2) message and wireless access network applying portion call control protocol (RANAP) message, signalling point is the node that needs to transmit signaling in the signaling network, and signaling point code is the coding that is used for identifying signalling point.
Be illustrated in figure 1 as the 3G R4 schematic network structure of recommending in the standard, three different signaling point codes of hold facility are used for intercoming mutually, require RNC identification MSC_Server and two equipment of MGW, can send RANAP message and Q.AAL2 message to MSC_Server and MGW respectively.
Be illustrated in figure 2 as the underlying protocol stack figure of Q.AAL2, be illustrated in figure 3 as the underlying protocol stack figure of RANAP, SAAL is a signaling asynchronous transmission mode adaptive layer, SCCP is a SCCP, MTP3B is the 3rd layer of a broadband Message Transfer Part, two kinds of signalings all finally are carried on the broadband Message Transfer Part the 3rd layer (MTP3B), in the R99 network, because two agreements are local a processing, so the MTP3B signaling point code only needs one, discerns different upper-layer users by the user ID of MTP3B then; At the R4 network, because two agreements are handled on different equipment, just need two MTP3B signaling point codes, the radio network controller in the R4 network (RNC:Radio Network Controller) needs respectively Q.AAL2 message and RANAP message to be sent on the various signalling points.
Because R4 network requirement RNC must discern MSC_Server and MGW simultaneously, otherwise can't insert, RNC in the former like this R99 network just can not insert the R4 network, for the R99 RNC that can discern two equipment simultaneously, also need to revise the data configuration interrupting service, access R4 network that can not be level and smooth, and need to increase transmission lines between RNC and MSC_Server.
Summary of the invention
Technical problem to be solved by this invention is: overcome the deficiencies in the prior art, the method that inserts the R99 radio network controller in a kind of WCDMA of realization mobile communication R4 network is provided, thereby make full use of conventional network equipment, realize that the conventional network equipment graceful upgrade is to the R4 network.
The present invention solves the problems of the technologies described above the technical scheme that is adopted to be:
This in the Wideband Code Division Multiple Access (WCDMA) mobile network method of access of radio network controller, may further comprise the steps:
A, radio network controller (RNC) are all delivered to media gateway (MGW) with bearer control protocol message and calling control protocol message;
B, MGW handle the bearer control protocol message of receiving oneself, the calling control protocol message of receiving is transmitted to mobile services switching centre server (MSC_Server) handles;
C, on MSC_Server, MGW is configured to arrive the Signaling Transfer Point of RNC, calling control protocol message is sent to MGW earlier, be transmitted to RNC by MGW again.
On MGW, when identification message is SCCP (SCCP) protocol message, will be from the SCCP message that RNC receives the information relevant with destination signaling point sign indicating number (DPC) make the signaling point code of MSC_Server into, be transmitted to MSC_Server then and handle; Will be from the SCCP message that MSC_Server receives the information relevant with former signaling point code (OPC) make the signaling point code of MGW into, be transmitted to RNC then and handle.
Message between MGW and MSC_Server can be transmitted by broadband Message Transfer Part the 3rd layer (MTP3B), also can be transmitted by the 3rd layer of user adaptation layer of Message Transfer Part (M3UA).
Beneficial effect of the present invention is: the present invention realizes the forwarding of RANAP message between radio network controller (RNC) and the mobile services switching centre server (MSC_Server) by media gateway (MGW), thereby do not need RNC to discern MSC_Server and two equipment of MGW simultaneously, make the access R4 network that R99 RNC can smooth and seamless, thereby can make full use of conventional network equipment, the graceful upgrade of realization conventional network equipment has been saved investment to the R4 network.

Embodiment
With embodiment the present invention is described in further detail with reference to the accompanying drawings below:
As shown in Figure 4, in the present invention, radio network controller (RNC) all is sent to media gateway (MGW) to asynchronous transfer mode adaptation layer two bearer control protocol (Q.AAL2) message and wireless access network applying portion call control protocol (RANAP) message, RNC does not also know that core net is R99 or R4 network, like this, MGW will receive Q.AAL2 message and RANAP message simultaneously, Q.AAL2 message is handled by MGW oneself, and the RANAP forwards handles for mobile services switching centre server (MSC_Server).
MSC_Server can discern RNC and MGW simultaneously, on MSC_Server, MGW is configured to arrive the Signaling Transfer Point of RNC, thereby RANAP message is sent to MGW earlier, is transmitted to RNC by MGW again.
On MGW, when identification message is SCCP (SCCP) protocol message, MGW will make the signaling point code of MSC_Server into the relevant information of destination signaling point sign indicating number (DPC) from the SCCP message that RNC receives, be transmitted to MSC_Server then and handle; Will be from the SCCP message that MSC_Server receives the information relevant with former signaling point code (OPC) make the signaling point code of MGW into, the DPC relevant information is constant, being transmitted to PNC then handles, as shown in Figure 4, if the signaling point code of RNC is 1, the signaling point code of MGW is 2, and the signaling point code of MSC_Server is 3, and translation process is as follows:
(1) RNC is to the SCCP message of MGW, and OPC is 1, and DPC is 2, after MGW receives this message, information relevant with DPC in the message is made into 3, is transmitted to 3 and handles;
(2) MSC_Server is to the SCCP message of MGW, and OPC is 3, and DPC is 1, by MTP3B message is sent to 2, after MGW receives this message, information relevant with OPC in the message is made into 2, and the DPC relevant information is constant, is transmitted to 1 and handles.
Message between MGW and MSC_Server can be transmitted by broadband Message Transfer Part the 3rd layer (MTP3B), also can transmit by the 3rd layer of user adaptation layer of Message Transfer Part (M3UA), M3UA uploads to deliver letters at IP to make protocol of messages, concrete using method and notion are all similar with MTP3B, also are by the signaling point code addressing.
Like this, by the conversion of MGW, the RNC of R99 just can be directly communicates with MGW and the MSC_Server of R4, has realized seamless access R4 network.
