Embodiment Construction

[0037] In order to make the objects 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] First of all, the method for preventing the user from dropping calls in the static migration of the embodiment of the present invention is introduced, Figure 4 The flow of the method is shown, and the flow includes the following steps during the execution of the static migration:

[0039] Step 401: the DRNC receives the RLC sequence number information sent by the SRNC corresponding to the UE.

[0040] In this step, the SRNC may carry the RLC sequence number information through a message sent to the DRNC, such as a relocation request message.

[0041] Step 402: the DRNC uses the RLC sequence number information to process the PDU sequence sent by the UE.

[0042] In this step, the DRNC can complete the processing of the PDU sequence s...

Abstract

The present invention provides a method for preventing user disconnecting in static migration, wherein the method in the executing course of static migration comprises the following procedures: receiving radio link control RLC sequence number information transmitted by a service radio network controller SRNC corresponding with user equipment UE by a drifting radio network controller DRNC; and processing the protocol data unit PDU sequence transmitted by UE by DRNC with the RLC sequence number information. The invention also provides a system for preventing user disconnecting in static migration and a radio network controller RNC. The application of the invention can settle the problem of user disconnecting when PDU sequence is transmitted by UE to DRNC and increase the user experience in the period when the RLC sequence number information sustained by UE and DRNC is not consistent in the static migration.

Description

technical field [0001] The present invention relates to the field of Universal Mobile Telecommunication System (UMTS), in particular to a method, system and device for preventing user call drop in UMTS static migration. Background technique [0002] The current UMTS network structure such as figure 1 As shown, it mainly includes a core network (Core Network, CN), a UMTS Terrestrial Radio Access Network (UMTS Terrestrial Radio Access Network, UTRAN) and a user terminal (User Equipment, UE). Among them, CN includes packet (PacketSwitched, PS) domain and circuit (Circuit Switched, CS) domain, connected with radio network controller (Radio Network Controller, RNC) through Iu interface; UTRAN includes RNC and base station (Node B), RNC It is connected to Node B through Iub interface, and different RNCs are connected through Iur interface; RNC and Node B form a radio network control system (Radio Network System, RNS); UE is connected to Node B through Uu interface, and Uu interfa...
