Business establishment control method and system in long-term evolution network and terminal device

Abstract

A method, system and terminal device for service establishment control in a long-term evolution network, which can effectively increase the speed of the service establishment, are provided in the present invention. The method includes the following steps: a User Equipment (UE) monitors a paging message from the network side in the Radio Resource Control (RRC) connection restriction state, wherein the paging message indicates the system message of the UE has been modified; the UE reads the modified system message according to the paging message, and judges, according to the modified system message, whether the RRC connection is restricted; if the UE determines that the RRC connection is not restricted, then the RRC layer of the UE sends the restriction release information to the Non Access Stratum (NAS). The present invention judges whether the RRC connection is still restricted by monitoring the paging message from the network side, and notifies the NAS timely in the state of determining the RRC connection is not restricted, so as to initiate the RRC connection establishment request to the network side again as soon as possible. The present invention can effectively accelerate the process for establishing corresponding service between the UE and the network side, thus increasing the response speed of the LTE network.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a service establishment control method, system and terminal equipment in an LTE (Long Term Evolution: Long Term Evolution) network. Background technique [0002] At present, 3G (The 3rd Generation: third-generation mobile communication) technology has been widely used. In order to meet the growing demand of users for mobile data services, the 3GPP (The 3rd Generation Partnership Project: third-generation mobile communication) launched for 3G technology Standards Partnership Program) has received increasing attention accordingly. In order to make the 3GPP wireless access technology in a favorable position in the fierce competition in the field of mobile communication in the future, it is necessary to consider the long-term evolution of the 3GPP wireless access technology. The LTE network based on the long-term evolution can effectively improve and enhance the 3G air acces...

Problems solved by technology

For the RRC connection of the emergency call and the called type, since the emergency call has no time limit, the NAS can repeatedly try to establish a link, and when the called party is limited, the network side sends an RrcConnectionReject (RRC link establishment rejection) to the UE 10 ) message, so these two types of RRC connection control are out of the scope of the present invention

[0006] In practical applications, during the running of the timer, the core network 30 or the access network 20 may release some resources due to the completion of some UE 10 services, so that the overload situation has been alleviated, so the service restrictions on Mo data or Mo signaling can be lifted However, according to the existing standard, RRC will not try to establish an RRC connection again until the timer expires. This situation delays the process of establishing an RRC connection between UE 10 and the network side to a certain extent, and has a certain impact on the speed of establishing communication services.
