Description

Network name and service type information display method, device and system

The embodiments of the present invention relate to the field of communications technologies, and in particular, to a network name and a service type display method, apparatus, and system.

Background technique

The 3GPP organization has introduced the Evolved Packet System (EPS) based on existing 2G and 3G networks. The EPS network includes an Evolved Universal Mobile Telecommunication System Territorial Radio Access Network (E-UTRAN) and an Evolved Packet Core Network (EPC). Since the EPS network only handles Packet Switched (PS) services, operators currently use the original Circuit Switched (CS) to provide CS services. 3GPP extends the Gs interface function between the Mobile Switching Center (MSC)/Visitor Location Register (VLR) and the Serving GPRS Support Node (SGSN) in the existing 2/3G network. The SGs interface between the MSC/VLR and the Mobility Management Entity (MME) is defined in the EPS network. Based on the SGs interface function, 3GPP proposed "CS Fallback" (CSFB) technology and SGs short message transmission technology (SMS over SGs). The CSFB technology enables the user equipment (User Equipment, UE) under the E-UTRAN coverage to complete the service processing through the E-UTRAN back to the 2G/3G network CS domain when the CS voice service needs to be processed; the SMS over SGs technology allows the resident in the E- The terminal in UTRAN reuses the existing CS domain device to implement CS short message transmission. In the CSFB or SMS over SGs scenario, in the UE-initiated joint attach process or the joint tracking domain update process, if multiple available Public Land Mobile Networks (PLMNs) provide CS services for them, the MME According to the PLMN reported by the evolved base station (evolved NodeB, eNodeB), the tracking domain location information of the current UE and the operator CS network selection policy, an appropriate PLMN is selected. After completing the update process, both the UE and the MME need to save the selected PLMN ID and the home domain information corresponding to the PLMN ID.

Similarly, in the traditional 2/3G scenario, in the UE-initiated joint attach procedure or the joint tracking domain update procedure, the SGSN also selects a suitable PLMN for the UE. After the update process is completed, both the UE and the SGSN need to save the selected PLMN ID and the home domain information corresponding to the PLMN ID. In the prior art, the UE displays the network name in two ways: (1) the UE displays the network name according to its own configuration; (2) the network side sends the network name to the UE for display.

There are two methods on the network side to send the network name to the UE: (1) In the CSFB or SMS over SGs scenario, the MSC/VLR sends its registered network name to the MME through the SGs interface, or in the traditional 2/3G network. The MSC/VLR sends the domain name of the home domain registered by itself to the SGSN through the Gs interface. The MME or SGSN forwards the network name to the UE through a Mobile Management INFORMATION (MM INFORMATION) procedure. (2) The MME or the SGSN sends the registered home network name registered by itself to the UE.

In the prior art, the UE can only display the network name, and cannot display the corresponding data service or type information of the voice service, and the user experience is reduced.

Summary of the invention
