Method for establishing connection between mobile station and evolution packet core network

Abstract

The method includes steps: receiving message from access layer of mobile station (MS), evolution radio access network (ERAN) establishes signaling connection between ERAN and MS based on signaling message of data as data unit of non access layer protocol carried by message from access layer of MS; at same time, ERAN establishes signaling connection between ERAN and evolution packet core network (EPCN) so as to build up signaling connection between MS and EPCN. In procedure for building signaling message between MS and EPCN, the invention builds up signaling message between MS and ERAN as well as signaling message between ERAN and EPCN at same time. Thus, the invention shortens time for building connection between MS and EPCN greatly so as to meet requirement on switching and accessing time put forward by evolution network.

Description

technical field [0001] The invention relates to a mobile communication network access technology, in particular to a method for establishing a connection between a mobile station and an evolved packet core network in an evolved network (Evolved Network). Background technique [0002] Universal Mobile Telecommunications System (UMTS) is a third-generation wireless communication network technology standard defined by the Third Generation Partnership Project (3GPP), which released REL-99, REL-4, REL-5 and REL-6 Version. The UMTS network consists of a core network (Core Network) and a UTMS Terrestrial Radio Access Network (UTRAN, UMTS Terrestrial Radio Access Network). The core network includes two parts, the circuit domain (CS, Circuit Switch) and the packet domain (PS, Packet Switch), wherein the circuit domain provides services based on circuit switching, such as voice services, and the packet domain provides services based on packet switching, such as the Internet ( Intern...

Problems solved by technology

In the case of an evolved network using an all-IP transmission network, the evolved network has strict requirements on fast access time. If the complex Iu interface protocol stack in the existing UMTS is continued to implement the S1 interface, the processing efficiency of the S1 interface will be reduced Therefore, if the existing method of establishing a signaling connection between the RNC and SGSN in UMTS is continued to implement the establishment of a connection between the evolved radio access network and the evolved packet core network, it will not be able to meet the access time requirements of the evolved network.
