Problems solved by technology

[0017] However, in the current cell reselection method, the UE cannot know whether the adjacent cell supports enhanced FACH and / or enhanced PCH when performing cell reselection. Therefore, when performing cell reselection, the UE using enhanced FACH cannot give priority Reselect to adjacent cells that support enhanced FACH, and UEs that use enhanced PCH cannot preferentially reselect to adjacent cells that support enhanced PCH

Embodiment Construction

[0034]The specific embodiment of the present invention is described below in conjunction with accompanying drawing:

[0035] Such as figure 1 Shown is a flowchart of an embodiment of the present invention, and the method includes the following steps:

[0036] 101: The network side issues a neighbor cell list and cell reselection parameters to UEs residing in the managed cell through a system message;

[0037] In this embodiment, when the UE is in idle mode, the RNC (Radio Network Controller, radio network controller) passes the SIB11 (SystemInformation Block type 11, system information block type 11) and SIB3 message in the RRC (Radio Resource Control) protocol (SystemInformation Block type 3, system information block type 3), deliver the adjacent cell list and cell reselection parameters to the UE.

[0038] The "Measurement control system information" (measurement control system information) information element of the SIB11 message includes: "Intra-frequency measurement sys...

Abstract

The invention discloses a subdistrict reselecting method which is applied to a third generation mobile communication enhancing high-speed packet access system. The subdistrict reselecting method comprises the following steps: a network lateral user device issues an abuttal subdistrict list and notifies the information whether subdistricts support an enhancing forward access channel and / or an enhancing paging channel in the abuttal subdistrict list to the user device; after the user device who uses the enhancing forward access channel constructs a reselecting subdistrict list, subdistrict residents who support the enhancing paging channel are preferentially selected from the reselecting subdistrict list according to the information whether supporting the enhancing forward access channel and / or the enhancing paging channel. The method ensures the service transmission continuity and avoids the UE unnecessary state transference.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a cell reselection method in the third-generation mobile communication enhanced high-speed packet access system. Background technique [0002] HSUPA (High Speed ​​Uplink Packet Access, High Speed ​​Uplink Packet Access) technology is a wireless side uplink enhancement technology introduced in the R6 version of the 3GPP (Third Generation Partnership Project) protocol system. HSUPA adopts key technologies such as multi-code transmission, HARQ (Hybrid ARQ, fast hybrid automatic retransmission) and fast scheduling based on Node B (Node B), so that the maximum uplink data throughput rate of a single cell reaches 5.76Mbit / s, greatly enhancing Uplink data service bearing capacity and spectrum utilization. [0003] HSDPA (High Speed ​​Downlink Package Access) technology mainly adopts AMC (Adaptive modulation and coding, adaptive coding and modulation) technology, HARQ and fast schedu...
