Embodiment Construction

[0040] The present invention provides a method for knowing the type of bearer service and completing the switching of the bearer network. When the bearer is established, the PCRF transfers the service type of the bearer to the bearer network, and the bearer network quickly and accurately completes the bearer service type information after learning the bearer service type information. User switching between bearer networks.

[0041] The present invention will be described in detail below in conjunction with the accompanying drawings:

[0042] As shown in 3 is a schematic diagram of the initial deployment of the EPS network, which is also the implementation scenario of the present invention in the EPS network. In the figure, only two cases are included: the first is the area covered by the EPS network, and the area with the EPS network has the UMTS / GSM network; the second, the coverage of the EPS network and the UMTS / GSM network are different, and some overlapping. However, in fact,...

Abstract

The invention provides a method which acquires a carrying service type and achieves a carrying switch. When the carrying is established, the carrying service type information is determined by a strategy and accounting rule function according to an application information which is provided by an application server; the carrying service type information is transmitted to a carrying network which judges a CS switch or a PS switch according to the carrying service type information which is acquired by the method and achieves corresponding switch. By adopting the proposal of the invention, the carrying network can acquire the carrying service type information when establishing the carrying and can fast and exactly achieve the switch when the subscriber demands the network switch.

Description

Technical field [0001] The present invention relates to a mobile communication system, in particular to a method for how a bearer network in an evolved packet domain system learns a bearer service type, and completes the bearer network switching according to the learned bearer service type. Background technique [0002] With the sudden emergence of Wimax (World Interoperability for Microwave Access), the third-generation mobile communication system must improve its network performance and reduce network construction and operation in order to maintain its strong competitiveness in the field of mobile communication. cost. Therefore, the standardization working group of 3GPP (3rd Generation Partnership Project, Third Generation Partnership Project) is currently committed to studying PS Core (Packet Switch Core) and UTRAN (Universal Mobile Telecommunication System Radio Access Network). The evolution of the wireless access network of the communication system, the subject of this rese...
