Problems solved by technology

Through the above analysis, it can be seen that the call setup process 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 of the GSM system (second generation mobile communication system). ) is still longer, therefore, for some services that are more sensitive to the call setup delay, it is necessary to reduce the call setup delay of the UMTS system to improve user satisfaction. In view of this, the present invention proposes a method for reducing the call setup delay Methods

Embodiment Construction

[0019] As shown in Figure 2: the method for the called terminal of the present invention to receive a call quickly comprises the steps:

[0020] Step A: CN initiates paging;

[0021] Step B: RRC connection establishment:

[0022] Step C: NAS signaling connection and NAS signaling interaction between UE and CN;

[0023] Step D: RAB radio access bearer.

[0024] The step B specifically includes the following steps:

[0025] Step B1: UE sends RRC connection request message to RNC, and NAS message (that is, service request and PPD activation request / SETUP message) is encapsulated in this message;

[0026] Step B2: RNC allocates relevant resources and configures NodeB; 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 transmission to RNC The bearer is established and determined; RNC sends downlink synchroni...

Abstract

The technology of this invention is used to provide a program of rapid receiving call at the Called end in Mobile Communication System, which includes the following steps: initiate paging at CN; RRC connections; NAS Signaling Link and NAS signaling interaction; RAB carrying wireless access. The features are that 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, which reduce subsequent delay and improve users' terminal satisfaction.

Description

technical field [0001] The invention relates to a method for a called terminal to quickly receive a call in a mobile communication system, in particular to a method for a called terminal to quickly receive a call / session in a third-generation mobile communication system (UMTS). Background technique [0002] In the communication system, the duration of call establishment (also known as 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, PoC (Push to talk Over Cellular), etc., the call setup delay in the current UMTS system is relatively long (generally 6-10 seconds), the purpose of the present invention is to reduce the call setup delay and improve user satisfaction. [0003] The following briefly introduces the called call establishment process in the UMTS system, taking the mobile station (UE) as an example to accept the call: the ...
