Embodiment 1

[0063] A CSFB processing method provided by an embodiment of the present invention is introduced in detail.

[0064] refer to Figure 4 , shows a flowchart of steps of a CSFB processing method in an embodiment of the present invention.

[0065] Step 100, adding an information element identifying circuit domain rollback capability in the S1 protocol layer control plane message.

[0066] The S1 protocol layer control plane messages may include: S1-AP UE Context Modification Request message, S1-AP UE Initial Context Setup Request message, S1Setup Response message, MME Configuration Update message.

[0067] The IE identifying the CSFB capability may be the IE identifying the CSFB capability supporting PS switching, or the IE identifying the CSFB capability not supporting PS switching.

[0068] Step 102: Send the S1 protocol layer control plane message carrying the information element identifying the CS domain fallback capability from the mobility management entity to the evolved...

Embodiment 2

[0072] A CSFB processing method provided by an embodiment of the present invention is introduced in detail.

[0073] refer to Figure 5 , shows a flowchart of steps of a CSFB processing method in an embodiment of the present invention.

[0074] Step 200, adding an IE identifying CSFB capability to the S1 protocol layer control plane message.

[0075] The S1 protocol layer control plane messages may include: S1-AP UE Context Modification Request message, S1-AP UE Initial Context Setup Request message, S1Setup Response message, MME Configuration Update message.

[0076] The IE identifying the CSFB capability may be an optional IE, and the IE may be an IE for identifying the CSFB capability that the core network supports PS handover, or an IE that identifies the CSFB capability that the core network does not support PS handover.

[0077] Preferably, according to the difference in the control plane information of the S1 protocol layer, the step 200 can be divided into the follow...

Embodiment 3

[0094] A CSFB processing system provided by an embodiment of the present invention is introduced in detail.

[0095] refer to Figure 6 , shows a schematic structural diagram of a CSFB processing system in an embodiment of the present invention.

[0096] The system may include: an information element adding module 300 and an information element sending module 302 .

[0097] The functions of each module and the relationship between each module are introduced in detail below.

[0098] The information element adding module 300 is configured to add an information element identifying circuit domain fallback capability in the S1 protocol layer control plane message.

[0099] Preferably, the information element identifying the circuit domain fallback capability is an optional information element; the information element identifying the circuit domain fallback capability is used to identify that the core network supports circuit domain fallback for packet domain handover or the core...

Abstract

The invention provides a method and a system for handling circuit domain rollback. The method comprises the following steps: information elements identifying circuit domain rollback performance is added in an S1 protocol layer control surface message; the S1 protocol layer control surface message carrying the information elements identifying circuit domain rollback performance is sent from a mobility management entity to an evolution base station so as to enable the evolution base station to carry out circuit domain rollback handling according to the information elements identifying circuit domain rollback performance. According to the invention, a signaling procedure of switching of each user is reduced; unnecessary signaling cost and switching time delays are cut down; equipment performance and taking-in and sending-out of air interfaces are improved; and the coupling between interoffice equipment software is reduced. Consideration is also given to compatibility of the protocol, and upgrading and realization of the equipment are provided with convenience.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a processing method and system for circuit domain fallback. Background technique [0002] Currently, CS Fallback (CSFB) is one of the main voice solutions of the 4th Generation mobile communication technology (4G). , PS) handover voice solutions and voice solutions that do not support PS handover, the voice solution that does not support PS handover is mainly because the user rate of the current second generation mobile communication technology (the 2nd Generation mobile communication technology, 2G) cell It cannot meet the requirements. Although the rate of the 3rd Generation mobile communication technology (3G) can be improved, there is still a gap compared with 4G and the coverage of 3G is not enough. Therefore, in order to improve the user's data For experience services, many operators choose to implement voice services through 3G networks, while data services...
