Problems solved by technology

[0007] However, if before the access transfer preparation procedure, the UE undergoes an inter-BSC / RNC handover in the CS domain, and the UE does not enter the connected state in the PS domain during the process of connecting to the target BSC / RNC, then the above The target BSC / RNC does not have the SGSN address of the above UE
In the subsequent access transfer preparation process, since the above-mentioned target BSC / RNC does not have the SGSN address of the UE, it cannot carry the SGSN address in the rSRVCC handover request message, so the MSC cannot know the UE's SGSN address, resulting in the subsequent access transfer preparation process can not achieve

Embodiment 1

[0034] figure 1 It is a flow chart at the source BSC / RNC side of Embodiment 1 of the handover processing method according to the embodiment of the present invention. Such as figure 1 As shown, the method comprises the following steps at the source BSC / RNC side:

[0035] Step 101, during the handover process of the CS domain of the terminal, the source BSC / RNC acquires the SGSN address saved for the terminal in itself.

[0036] The CS domain handover process in this step refers to the handover process performed within the CS domain, such as inter-BSC / RNC handover in the CS domain.

[0037] This step can be performed before the source BSC / RNC sends a handover request to the MSC, and can also be performed after the source BSC / RNC determines that the target BSC / RNC of the CS domain handover is in the same routing area as the source BSC / RNC (RouteArea, RA), the step of obtaining the SGSN address is executed. If the source BSC / RNC determines that the target BSC / RNC of the CS dom...

Embodiment 2

[0052] figure 2 It is a flow chart of Embodiment 2 of the switching processing method according to the embodiment of the present invention, as shown in figure 2 As shown, the method includes the following steps:

[0053] Step 201, during the terminal CS domain switching process, the MSC receives the SGSN address from the source BSC / RNC, and saves the SGSN address. In this step, the SGSN address may be carried in the handover request.

[0054] Step 202, during the handover process of the terminal rSRVCC, the MSC reads the SGSN address saved by itself, and sends a handover request from the CS domain to the PS domain to the SGSN according to the address.

[0055] The step before the MSC reads the SGSN address saved by itself may include:

[0056] The MSC receives a handover request for rSRVCC from the BSC / RNC;

[0057] The MSC judges whether the received handover request includes an SGSN address, and if so, sends a handover request from the CS domain to the PS domain to the...

Embodiment 3

[0060] In this embodiment, during the handover process of the terminal CS, the source BSC / RNC sends the SGSN address to the MSC, and the MSC saves the address for the implementation of the access transfer preparation process in the subsequent rSRVCC handover.

[0061] Such as image 3 As shown, the handover processing method in this embodiment includes the following steps:

[0062] Step 301, the terminal sends a measurement report to the source BSC / RNC.

[0063] Step 302, the source BSC / RNC sends a handover request to the MSC.

[0064] The schemes involving handover request triggering in step 301 and step 302 are the same as those in the prior art, and since they have been described in detail in various relevant standard protocols, details will not be repeated here.

[0065] But in step 302, when the BSC / RNC finds that the current handover is a normal CS domain handover (i.e. non-interMSC handover), and the RA has not changed, it reads the SGSN address saved for the terminal...

Abstract

An embodiment of the invention provides a switching processing method, network equipment and a network system. The switching processing method includes: during CS (circuit service) domain switching of a terminal circuit, a source BSC (base station controller) / RNC (radio network controller) obtains an SGSN (serving general packet radio service support node) address stored therein for a terminal; and the source BSC / RNC transmits the SGSN address to an MSC (mobile switching center) during CS domain switching. By the switching processing method, the equipment and the network system in the embodiment, during CS domain switching, the source BSC / RNC transmits the SGSN address to the MSC, and the MSC directly can obtain the SGSN address or can further transmit the SGSN address from the source BSC / RNC to a target BSC / RNC, so that success rate that the MSC obtains the SGSN address of UE (user equipment) during subsequent rSRVCC (reverse single radio voice call continuity) switching is increased, and the success rate of achieving an access transfer preparation process is also increased.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communication, and in particular, to a handover processing method, a network device, and a network system. Background technique [0002] The second generation mobile communication technology (2ndGeneration, 2G) or the third generation mobile communication technology (3rdGeneration, 3G for short) network has formed a situation of comprehensive coverage after years of deployment. At the same time, with the development of network technology, some pure PS domain networks that only provide Packet Switching (PS for short), such as Long Term Evolution (LTE for short) networks, have gradually covered To some urban areas and traffic hotspots. Therefore, in the current communication network, these pure PS domain networks and 2G / 3G networks are in a state of coexistence. [0003] Corresponding to different communication networks, voice services have different bearer mechanisms. Specifica...
