Embodiment 1

[0046] Embodiment 1 provides a method for the RNC to clarify the RNC-ID resolution method in the broadcast signaling, such as figure 2 shown.

[0047] Step 110: The RNC broadcasts a SIB type 3 and / or SIB type 4 message, and carries a cell identity information element and an indication information element of the RNC-ID resolution mode in the message.

Embodiment 2

[0048] Embodiment 2 provides a method for the UE to update the local RNC-ID parsing method during the RRC establishment process. like image 3 shown.

[0049] Step 210: The UE initiates an RRC connection establishment request message from the cell 200 .

[0050] Step 220: The RNC sends an RRC connection establishment message, in which the NewU-RNTI information element is carried.

[0051] Step 230: The UE sends an RRC connection establishment complete message, and at the same time updates the local RNC-ID resolution method according to the RNC-ID resolution method broadcast by the SIB type 3 and / or SIB type 4 message of the cell 200 .

Embodiment 3

[0052] Embodiment 3 provides a method for the RNC to clarify the RNC-ID resolution method and the UE to update the local RNC-ID resolution method in the downlink reconfiguration signaling, such as Figure 4 shown.

[0053] Step 310: During incoming relocation, the target RNC sends a cell update confirmation message or a URA update confirmation message or a physical channel reconfiguration message or a transport channel reconfiguration message or a radio bearer reconfiguration message to the UE through the source RNC, or during an incoming inter-system handover , the target RNC sends a switch-in UTRAN command message to the UE through the source wireless access system, and the message carries a New U-RNTI information element and an indication information element of an RNC-ID resolution mode at the same time.

[0054] Step 320: The UE sends a UTRAN mobility information message or a physical channel reconfiguration confirmation message or a transport channel reconfiguration confi...

Abstract

The invention provides an indication method of a radio network controller-identification (RNC-ID) analytic mode, comprising the following steps: an RNC sends out a broadcasting signaling with a section ID cell and the indication of the RNC-ID analytic mode to UE; the UE adopts the radio source control connection to access the RNC-ID analytic mode indicated by the section broadcasting signaling as a local RNC-ID analytic mode in the process of establishing a radio source control connection; a destination RNC sends out a downlink reassortment signaling with a new U-RNTI and the indication of a new RNC-ID analytic mode to the UE; and the UE adopts the new RNC-ID analytic mode indicated by the downlink reassortment signaling as the local RNC-ID analytic mode in the process of adopting the new U-RNTI to set relocation or inter-system switching. The invention can confirm the RNC-ID analytic mode in a mobile communication system to further reduce the call drop rate.

Description

technical field [0001] The present invention relates to the field of communication, in particular to a method for indicating a resolution mode of a Radio Network Controller Identity (RNC-ID for short) in a mobile communication system. Background technique [0002] The 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as 3GPP) defines in the 25.331 protocol between a radio network controller (Radio Network Controller, referred to as RNC) and a user equipment (User Equipment, referred to as UE). Each UE with a radio resource connection (Radio Resource Connection, RRC for short) is assigned a U-RNTI (Universal Terrestrial Radio Access Network-Radio Network Temporary Identity). U-RNTI contains 2 parts with a total of 32 bits, one part is the Serving RNC identity (SRNC identity for short), which occupies the upper 12 bits, and is used to uniquely identify the RNC in the Public Land Mobile Network (PLMN for short); the other part is the serving RN...
