Problems solved by technology

[0011] In practical applications, the calling process between the calling terminal and the called terminal is the main process in the call, most of the time without the participation of MGW-O and MGW-T, but because MGW-O and MGW-T are in the bearer path, all All user voice data must pass through MGW-O and MGW-T, which undoubtedly increases the transmission time of user data and is not conducive to the improvement of voice quality
[0012] It can be seen that in the prior art, there is no method for call processing on the network side, which can further save the transmission time of user data and improve voice quality

Embodiment 1

[0073] Figure 4 A schematic message flow diagram of call processing on the network side in this embodiment is shown. Such as Figure 4 As shown, the method for implementing call processing on the network side in this embodiment includes the following steps:

[0074] Step 401: RNC-O conducts encoding negotiation with RNC-T through MSC-S-O, MGW-O, MSC-S-T, and MGW-T.

[0075] Step 402: MSC-S-O and MSC-S-T respectively establish bearers on MGW-O, RNC-O, MGW-T and RNC-T.

[0076] Steps 403 to 404: MSC-S-O sends an update bearer request message carrying RNC-O network-side endpoint information to MSC-S-T, and MSC-S-T returns an update bearer response message carrying RNC-T network-side endpoint information to MSC-S-O.

[0077] In practical applications, the SIP protocol may be used between MSC-S-O and MSC-S-T, and the BICC protocol may also be used. If the SIP protocol is adopted, the bearer update request message in this step may be an UPDATE request message in the SIP protoc...

Embodiment 2

[0091] Figure 7 A schematic diagram of a message flow for bearer recovery in this embodiment is shown. Such as Figure 7 As shown, the method for implementing bearer recovery in this embodiment includes the following steps:

[0092] Steps 701 to 702: MSC-S-O sends an increase bearer request message to MGW-O, MGW-O allocates user-side endpoints and network-side endpoints for bearer, and returns to MSC-S-O carrying its own user-side endpoint information and network The addition of side endpoint information bears a response message.

[0093] Step 703 to Step 704: MSC-S-O sends an update bearer request message carrying MGW-O user-side endpoint information to RNC-O, and RNC-O / RNC-T changes the associated endpoint of its own network-side endpoint to MGW-O user The side endpoint returns an update bearer response message to the MSC-S-O.

[0094] Steps 705 to 706: MSC-S-O sends an update bearer request message carrying RNC-O network-side endpoint information to MGW-O, and MGW-O se...

Abstract

The invention provides a processing method of network side right call, the key lies in that associate the real-time host-host protocol (RTP) endpoints of radio network controller (RNC-O) and the target radio network controller (RNC-T) network. After the code negotiation and loading establishment, the source mobile soft switch (MSC-S-O) send the message requesting to update the loading carried with RNC-O network side RTP endpoint message to the target mobile soft switch (MSC-S-T); MSC-S-T then return the loading response message carrying with RNC-O network side RTP endpoint message back to the MSC-S-O; MSC-S-O will associate the RNC-O network side RTP endpoint with RNC-T network RTP endpoint, MSC-S-T will associate the RNC-T network side RTP endpoint with RNC-O network RTP endpoint; Then, communicate with each other according to the new loading path. With scheme of this invention, can transmit user's voice data packets directly between the RNC-O and RNC-T, without going through the media gateway, can further enhance voice quality and save resources.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a method for network side call processing. Background technique [0002] The mobile communication network is evolving from the traditional pure circuit network to the ALL IP network, and in the current WCDMA R4 stage, the softswitch architecture with separation of bearer and control is introduced into the core network circuit domain. The original mobile switching center (MSC) is divided into two devices: a mobile softswitch (MSC Server) and a media gateway (MGW). Among them, the MSC Server is used for signaling control, while the MGW is responsible for bearer processing. [0003] Based on the softswitch architecture that separates the bearer from the control, a method for communicating between mobile terminals, or between mobile terminals and terminals outside the public land mobile network (PLMN) is proposed at present, that is, free Codec operation (TrFO, Transcoder FreeOpera...
