Problems solved by technology

[0012] It can be seen that the call setup process in the prior art involves more signaling processes, resulting in a longer call setup delay. Data and tests show that the call setup delay in the UMTS system is longer than that in the GSM system (second generation mobile communication system). system) is still longer, therefore, for some services that are sensitive to call setup delay, it is necessary to reduce the call setup delay of UMTS system to improve user satisfaction

Embodiment Construction

[0019] Such as figure 2 Shown: calling end user call set-up method of the present invention comprises the steps:

[0020] Step A: RRC connection establishment:

[0021] Step B: NAS signaling connection establishment and NAS signaling interaction between UE and CN;

[0022] Step C: RAB radio access bearer.

[0023] Described step A specifically comprises the following steps:

[0024] Step A1: UE sends RRC connection request message to RNC, and NAS message (that is, service request and PPD activation request / SETUP message) is encapsulated in the message;

[0025] Step A2: RNC allocates relevant resources and configures Node B; specifically includes: RNC sends a radio link establishment request to NodeB; NodeB returns a radio link establishment response to RNC; RNC sends a data transmission bearer establishment request to NodeB; NodeB returns data to RNC The transmission bearer is established and determined; RNC sends downlink synchronization information to NodeB; NodeB send...

Abstract

The invention provides one method of rapid call setup options in a system for mobile communications, which includes RRC connections; NAS signaling connections and interactive; RAB Signaling carrying wireless access. Its characteristics, the link request message packages NAS news when the UE sends RRC connection request message to RNC; RNC transmits the NAS information to CN after receiving and analyzing the RRC called request information. CN based on NAS information can send RAB ordering news- RNC and assigned to paging call. The invention can reduce signaling interactive. At the same time, CN issued RAB allocation request message to the RNC much earlier. RNC completes the news analysis and configuration of the conversion after receiving CN distribution information requests. And sending calling ahead of time, shorting the subsequent delay, and then improving users' terminal satisfaction.

Description

technical field [0001] The present invention relates to a method for establishing a call in a mobile communication system, in particular to a method for establishing a call / session in a third-generation mobile communication system (UMTS). 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, emergency voice calls, For PoC (Push to talk Over Cellular), 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 the mobile station (UE) call as an example, the schematic diagram of the call es...
