A method for correct service network choice of the user terminal

Abstract

This invention discloses one method to select service network for user terminal, which comprises the following steps: setting interface ability label for UE; UE connecting the label into signal order to provide interface network or core network; interface network or core one judges whether UE has the ability of interfacing into network according to label; if the label has the ability, then UE has interface into internet ability for process.

Description

technical field [0001] The invention relates to a mobile communication network access technology, in particular to a method for correctly selecting a service network for a user terminal. 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 has released version-99 (REL-99), REL-4, REL -5 and REL-6. Figure 1 is a schematic diagram of the network structure of the prior art UTMS, as shown in Figure 1, the UMTS network is composed of a core network (Core Network) and a UTMS Terrestrial Radio Access Network (UTRAN, UMTS Terrestrial Radio Access Network), hereinafter referred to as UTRAN for short for the access network. The core network includes two parts, a circuit domain (CS, Circuit Switch) and a packet domain (PS, Packet Switch), wherein the circuit domain includes a mobile switching center / visitor location regi...

Problems solved by technology

[0008] The UTRAN and SGSN based on the existing UTMS cannot identify whether the UE has the ability to access the evolved network. Therefore, when the UTRAN is interconnected with the evolved packet core network of the evolved network, the UTRAN can only send the registration and service-related messages of the mixed UE. To the SGSN, select UTMS to provide services for the hybrid UE, the hybrid UE cannot register to the evolved network, and the user cannot use the services provided by the evolved network; similarly, when the UTRAN and the evolved packet core network of the evolved network are not interconnected, but the SGSN and the evolved packet core When the network is interconnected, the SGSN cannot send the hybrid UE's registration and service-related messages to the evolved packet core network, the hybrid UE cannot register with the evolved network, and the user cannot use the services provided by the evolved network

[0009] From the above analysis, it can be seen that when UTMS is interconnected with the evolved network, the existing technology cannot correctly select the service network for the hybrid UE, resulting in users who support both the evolved network and UMTS not getting better network services
