Problems solved by technology

[0018] The purpose of the present invention is to provide a method for transmitting messages on the air interface in fast call establishment, which mainly solves the problem that the existing call establishment process involves many signaling processes, resulting in a long delay in call establishment. This method is suitable for call establishment Latency-sensitive business

Embodiment Construction

[0042] The present invention provides a kind of air interface message transmission method in the fast call establishment, now take initiating a call to set up PoC business as an example, it encapsulates the service request (Service Request) message in the RRC connection request message, mainly includes the following steps:

[0043]Step 1: When the UE initiates a service that is sensitive to call setup delay, such as PoC service, the non-access stratum (NAS) of the UE indicates whether the RRC layer needs to start the fast call setup process. If not, the RRC will follow the 3GPP protocol 25.331 The description in is processed, that is, the RRC connection request process is directly initiated, and then after the RRC connection is successfully established, the Service Request message is sent to the CN through the UU interface initial direct transfer (Initial Direct Transfer, IDT) message and the IU interface direct transfer message; Proceed to step 2 if necessary:

[0044] Step 2...

Abstract

The method comprises: the service request message is packaged into the radio resource control connection request message; when user end initiates a calling, establishes the time-delay sensitivity service, and needs to start a fast call establishing process, it makes the non-key expansion for the radio resource control connection request message in order to add the service request message and the necessary access layer information into the expansion part; the necessary access layer information means the essential access layer cell in the initial directly-transmitted message; after radio network controller receives the expanded radio resource control connection request message, it packages the service request message of non access layer into the directly-transmitted message of IU interface, and then transmits the directly-transmitted message of IU interface to the core network.

Description

technical field [0001] The invention relates to a call / session establishment method of a third-generation mobile communication system (UMTS), in particular to a method for transmitting an air interface (UU) message in quick call establishment. Background technique [0002] In the communication system, the duration of call establishment (we are also called call establishment delay or connection delay) is an important factor affecting the quality of user service. Services sensitive to connection delay, such as interactive games, push-to-talk ( Push to talk Over Cellular (PoC for short), etc., the call establishment delay in the current UMTS system is relatively long (generally 6-10 seconds), and the purpose of the present invention is to reduce the call establishment delay and improve user satisfaction. [0003] The following briefly introduces the call establishment process in the UMTS system. Taking a mobile station (UE) calling another mobile station as an example, the sche...
