Description
Technical Field
The present invention relates to a mobile communication network, and in particular, to a method and a system for implementing terminating network selection in an idle state of a single radio channel access dual mode User Equipment (UE).
Background
In order to maintain the strong competitiveness of the third generation mobile communication system in the mobile communication field, it is necessary to improve the network performance thereof and reduce the network construction and operation costs. Therefore, the standardization working group of the third generation partnership project (3GPP, 3rd generation partnership project) is currently working on the evolution of the packet switched core network (PSCore) and the universal mobile telecommunications system radio access network (UTRAN), in order to make the evolved PSCore (PSCore may be abbreviated as EPC), provide higher transmission rate, shorter transmission delay, and support mobility management between the evolved UTRAN (E-UTRAN), Gsm Edge Radio Access Network (GERAN), UTRAN, Wireless Local Area Network (WLAN), and other access networks other than 3 GPP. This evolved mobile communication system is called an evolved packet domain system (EPS). Wherein, the GSM is an abbreviation of global system for mobile communications, i.e. global system for mobile communications; the above mentioned EDGE is an abbreviation of enhanced data rate for GSM evolution, i.e. enhanced data rate GSM evolution.
The network architecture after the EPS is introduced is shown in fig. 1, and the following description is given to each entity in fig. 1:
the UE 101: a UE with the capability to access both wireless networks is referred to as a dual mode UE. According to the capability of accessing a wireless network simultaneously, dual-mode UE can be divided into two types of single wireless channel access and dual wireless channel access, which can be respectively called single wireless channel access dual-mode UE and dual wireless channel access dual-mode UE. The single wireless channel access dual-mode UE can only access one wireless network at the same time; the dual-wireless channel access dual-mode UE can be simultaneously accessed to two wireless access networks. This document relates to single radio channel access to a UE. Wherein, the wireless channel is expressed by SingleRadio, abbreviated as SR.
EPS 102: including evolved radio networks and core networks.
Home Subscriber Server (HSS) 103: the system comprises a Home Location Register (HLR) function, and stores basic data and service data of a user.
GERAN/UTRAN 104: radio access network of a conventional GSM/UMTS network.
Mobile Switching Center (MSC), mobile switching center/Visitor Location Register (VLR) 105: the user may be provided with services of a Circuit Switched (CS) network, such as voice calls, etc.
Gateway mobile switching center (GMSC, gateway mobile switching center) 106: querying the routing information of the subscriber and routing the call to a mobile switching office (VMSC) or IMS network currently visited by the mobile subscriber based on the routing information.
When the UE accesses the GSM/UMTS network, the basic voice service and the supplementary service based on the voice service of the user are provided through the CS network, the MSC/VLR and GMSC in fig. 1 belong to a network element of the CS network, and the user can perform the voice call service with the user in the CS network or other networks, i.e. non-operator IP networks, such as a fixed telephone network and other mobile networks.
When the UE accesses the EPS network, the basic voice service of the user and the supplementary service based on the voice service are controlled by an IP network of an operator, such as an IP Multimedia Subsystem (IMS), and the EPS system itself cannot provide and control the voice call service, but only provides a bearer of IP data. Here, for IMS, IMS is an IP-based network architecture proposed by 3GPP, which constructs an open and flexible service environment, supports multimedia applications, and provides rich multimedia services for users. The IMS is an IP-based telecommunication network architecture, is independent of an access technology, and can provide services for packet access networks such as EPS, General Packet Radio Service (GPRS), and WLAN, and can also provide services for CS networks of mobile cellular networks such as GSM and Universal Mobile Telecommunications System (UMTS). Wherein, the internet protocol is expressed by internet protocol, abbreviated as IP.
As shown in fig. 2, which is a selection process of a single radio channel accessing a dual-mode UE terminating network in the prior art, a GMSC receives a remote address initial message and obtains a route to an HSS, at this time, the UE may have registered in both an IMS network and a CS network, for example, the UE moves to the CS network for registration after the IMS registration is completed, the HSS preferentially selects a network originating call according to an operator policy, for example, the IMS network is selected first, and when a call attempt fails, another network is selected for a new call attempt, which specifically includes the following steps:
step 201, the GMSC receives an address initial message sent by a Remote device (Remote), and establishes a call request message, where the call request message carries a called number.
Step 202, receiving the call request message, the GMSC sends a routing request message to the HSS to which the called party belongs according to the called number parsed from the call request message, and acquires the current routing information of the called party.
Step 203, the HSS selects a service network after receiving the routing request message, and when determining that the current user has successfully registered in both the IMS network and the CS network, the HSS preferentially selects the IMS network as the service network for service according to the operation policy.
Step 204, the HSS returns a routing request response message containing the IMS routing number to the GMSC.
Step 205, the GMSC sends a session invite message to the IMS network according to the IMS routing number, and routes the call to the IMS network.
Step 206, the IMS network sends a session invite message to the UE.
Step 207, the UE is not in the IMS network at this time, and the IMS waits for the UE response time out.
Step 208, the IMS network returns a session invitation failure message to the GMSC indicating that the called user has no response.
Step 209, if the GMSC does not receive the routing information of the CS network in step 204, a rerouting procedure needs to be performed, that is: the GMSC needs to resend the routing request message to the HSS in order to acquire the CS routing number.
Step 210, the GMSC sends an address initial message to the target MSC according to the CS routing number.
Step 211, the target MSC receives the address initial message, performs paging to the called party, and sends a call setup request message to the called party.
From an analysis of the flow of fig. 2, it can be seen that: when the UE moves between the IMS network and the CS network, the HSS may not know which network the UE currently resides in specifically, for example, the UE is previously retained in the CS network and then moves to the IMS network.
In summary, because the UE registration state where the UE previously resided cannot be timely cancelled, two UE registration states may exist, that is, the UE registration state includes the UE registration state where the UE currently resides in the network, and also includes the UE registration state where the UE previously resides in the network, so that when the HSS receives a routing request message for an incoming call of the UE, the HSS may select a user service network according to one UE registration state according to the operation policy according to the flow shown in fig. 2, and perform a call trial, obviously, the flow shown in fig. 2 has the following disadvantages: calling the UE may need to call twice to actually connect the call, which may cause the delay of the call when the UE terminates the call to increase, and reduce the user experience. At present, an implementation scheme for pre-selecting a single radio channel access UE terminal call is urgently needed, and time delay can be reduced so as to improve user experience.
