Problems solved by technology

[0017] Another problem is that the frequency layer convergence offset in LCI is the same for all MBMS services in a cell, while the existing messages on MCCH are for each service

Embodiment Construction

[0036] According to the present invention, because frequency layer convergence will be realized by modifying the existing cell reselection process, so first briefly introduce the relevant content of the existing cell reselection process (please refer to the specification TS 25.346 of 3GPP for the specific meaning of various parameters , V6.2.0 and TS 25.304, V6.0.0).

[0037] The UE calculates S according to the receiving power of the serving cell x (frequency division multiplexing cell: S qual , time division multiplexing cell: S rxlev ). In the absence of HCS (Hierarchical Cell Structure), the following principles need to be obeyed:

[0038] 1. If S x >S intrasearch , the UE does not need to perform intra-frequency measurement.

[0039] If S x intrasearch , the UE needs to perform intra-frequency measurement.

[0040] If the S of the serving cell intrasearch If not sent, the UE needs to perform intra-frequency measurements.

[0041] 2. If S x >S intersearch , the U...

Abstract

The method includes: subscriber equipment receives the system message from radio network controller; the system message includes the convergence deviation message of frequency layer; when session begins, the radio network controller sends the multi media broadcast and multicast message including the convergence message of the said layer to the subscriber equipment. The convergence message of the said layer includes the frequency information of firstly selected layer in current location and the ID of cell in the firstly selected layer cell; the subscriber equipment decides if itself is at the firstly selected layer in term of the frequency information in the layer convergence message in the received broadcast and multicast message; if not, executes the reselection of cell in term of the ID of cell in the convergence message of the said layer and the convergence deviation information of the frequency layer.

Description

technical field [0001] The present invention proposes a method for processing Layer Convergence Information (LCI) in multimedia broadcast and multicast services in a mobile communication system, especially in a WCDMA (Wideband Code Division Multiple Access) mobile communication system, more specifically , a method for processing layer convergence information in multimedia broadcast and multicast services is proposed, which is used to support the improved LCI introduced by FLC (frequency layer convergence) when MBMS (multimedia broadcast and multicast services) services are provided A processing method provided for the content of (layer convergence information). Background technique [0002] Multimedia Broadcast and Multicast Service (hereinafter referred to as MBMS) is a new service being standardized by the Third Generation Partnership Project (hereinafter referred to as 3GPP). The MBMS service is a one-way point-to-multipoint service. The biggest feature of this service i...
