Embodiment 1

[0047] Figure 6 It is a flow chart of the first preferred embodiment of the method of the present invention. In this embodiment, it is assumed that the source RNC of the UE is the NB+ in the Standalone scenario in the evolved HSPA UTRAN network, and the target RNC of the UE is the RNC in the UMTS network. Among them, the NB+ is connected to the core network through the Iu_CS signaling interface; the NB+ is connected to the target RNC through a newly added interface, such as an Iur interface. When a UE camped on NB+ initiates a CS service call, NB+ and the target RNC in the UMTS network supporting CS services perform inter-frequency hard handover. For the convenience of description, the target RNC is referred to as RNC for short below. Such as Figure 6 shown, including the following steps:

[0048] Step 601: UE sends an initial direct transfer message to NB+.

[0049] In this step, the UE initiates a CS call under the cell (CELL) controlled by the NB+, and sends an initi...

Embodiment 2

[0071] Figure 7It is a flowchart of the second preferred embodiment of the method of the present invention. In this embodiment, it is assumed that the source RNC of the UE is the NB+ in the Standalone scenario in the evolved HSPA UTRAN network, and the target RNC of the UE is the RNC in the UMTS network. It is assumed that there is no In_CS signaling connection between the NB+ and the MSC, but the NB+ and the RNC are connected through a newly added interface such as an Iur interface. When a UE camped on NB+ initiates a CS service call, NB+ and the RNC in the UMTS network supporting CS services perform inter-frequency hard handover. Such as Figure 7 shown, including the following steps:

[0072] Step 701: UE sends an initial direct transfer message to NB+.

[0073] In this step, the UE initiates a CS call under the CELL controlled by the NB+, and sends an initial direct transfer message to the NB+.

[0074] Step 702: NB+ determines that the service is a CS service accord...

Embodiment 3

[0082] Figure 8 It is a flowchart of the third preferred embodiment of the method of the present invention. In this embodiment, it is assumed that the source RNC of the UE is the NB+ in the Standalone scenario in the evolved HSPA UTRAN network, and the target RNC of the UE is the RNC in the UMTS network. It is assumed that there is no In_CS signaling connection between NB+ and MSC, but NB+ and RNC are connected through a newly added interface, such as an Iur interface. When a UE camped on NB+ initiates a CS service call, NB+ and the RNC in the UMTS network supporting CS services perform inter-frequency hard handover.

[0083] Such as Figure 8 As shown, the difference between this preferred embodiment and the second preferred embodiment is that when the wireless link bearer is established, the Iu bearer between the RNC and the MSC is established, that is, the Figure 7 Step 712 shown advances to Figure 8 The step 804a shown is executed, and the corresponding radio link r...

Abstract

An embodiment of the invention discloses a method and a system for supporting circuit switching field (CS) service in a high speed data access (HSDA) evolution network. User equipment (UE) under an evolution base station (NodeB+) initializes a CS calling. The NodeB+ initializes a relocating request to RNC through an interface arranged between the radio network controller (RNC) in the traditional network under standalone carrier scene. The RNC executes wireless parameter collocation and relocating preparation according to the relocating request and informs the container collocated for NodeB+ and RNC. The NodeB confirms initializing physical layer channel re-collocating information to UE according to the informing information. The UE executes radio link re-collocation according to the information in the physical layer channel re-collocating information and accesses the RNC for completing re-collocation. The application of the method and system defined in the embodiment of the invention can shorten the time delay in the establishing process of CS calling.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a method and system for supporting circuit domain services in a high-speed data access evolution network. Background technique [0002] The Universal Mobile Telecommunications System (UMTS) is a third generation (3G) mobile communication system that adopts Wideband Code Division Multiple Access (WCDMA) air interface technology, and the UMTS system is usually called a WCDMA communication system. The UMTS system adopts a structure similar to that of the second generation mobile communication system, such as figure 1 as shown, figure 1 It is a schematic diagram of the composition structure of the existing UMTS system. Depend on figure 1 It can be seen that the existing UMTS system mainly includes four parts: user terminal (UE), UMTS external radio access network (UTRAN), core network (CN) and external network. [0003] Among them, the CN is used to handle all voice calls and da...
