Embodiment Construction

[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0038] In the initial deployment stage of PS domain networks such as SAE / LTE, HSPA, HSPA+, and WiMAX, it is covered by hotspot areas, while 2G / 3G networks can be regarded as a kind of full coverage to some extent. In the embodiment of the present invention, the LTE network is selected as an example of the PS domain network to introduce the solution. It should be noted that the solution in the embodiment of the present invention is still applicable to the above-mentioned system.

[0039] Depending on whether the MSC needs to be upgraded to support the sending of the voice call paging message from the MSC to the MME, the current network can have two schemes of Architecture A and Architecture B.

[0040] Such as figure 1 As...

Abstract

The invention discloses a method, a device and a system for the user of PS domain to deal with the CS domain business and automatically choose whether to carry out the CS Fallback. When user equipment in the PS domain is adopted to deal with the call of the calling party from the CS domain and if the user equipment determines that the call meets the preset condition according to the instruction of the network side, the call is returned to the CS domain and the call of CS domain is carried out. The invention also discloses the user equipment and a mobile communication system. The invention leads the user equipment to carry out the CS Fallback automatically, which reflects the user desire that whether the user is willing to accept the calling; and as for the harassing calls which may come from the CS domain, the UE can avoid the unnecessary fallback.

Description

technical field [0001] The present invention relates to the field of communication, in particular to a technique for realizing the processing of circuit domain services by packet domain users. Background technique [0002] After years of deployment, 2G / 3G (second generation mobile communication technology / third generation mobile communication technology, such as GSM and WCDMA networks) networks can be regarded as a kind of comprehensive coverage to some extent. Nowadays, with the development of technology, SAE / LTE (System Architecture Evolution / LongTerm Evolution, system architecture evolution / long-term evolution), HSPA (High Speed ​​Packet Access, high-speed packet access), HSPA+ (High Speed ​​Packet Access Evolution, high-speed packet access Access Evolution) and WiMAX (Worldwide Interoperability for Microwave Access, Microwave Access Global Interoperability) networks have covered some areas, so in the current communication network, these networks coexist with 2G / 3G networ...
