Description

A method and device for cross-network location registration, update and paging

technical field

The invention relates to the technical field of network communication, in particular to a method and device for cross-network location registration, update and paging.

Background technique

With the development of network technology, it may appear that at least one wireless network is covered in an area, for example, LTE (Long Term Evlotion, long-term evolution plan or next-generation network) network and CS (Circuit Service Domain) network are covered in an area at the same time. , circuit domain, refers to the network element related to processing voice services in the 2G or 3G network) network. In this case, there are cross-network location registration and cross-network paging. Cross-network location registration, that is, when the UE (terminal) resides in Network1 (network 1), if a change in the location area of Network2 (network 2) is detected, the changed location area of Network2 will be registered through the access network of Network1. Perform location registration and updates. Cross-network paging means that when the mobile terminal resides in Network1, if it initiates a paging request or receives a paging response to Network2, it sends the paging request or receives the paging response through Network1.

The following uses the widely used LTE network as Network1 and the CS network as Network2 to illustrate specific applications of cross-network location registration and cross-network paging.

At present, the research and application of LTE network are being carried out extensively. Among them, it is determined that the VoIP (Voice Over IP, voice based on IP (Internet Protocol) protocol) provided by IMS is used to realize the voice service of the LTE network, and the VCC (Voice Call) based on IMS (IP Multimedia Subsystem, IP Multimedia Subsystem) is adopted. Continuity (voice call continuity) mode realizes switching between VoIP voice and traditional circuit domain voice, so as to ensure the continuity of UE voice services.

However, the IMS network has a lot of network element data, which is very difficult to construct, and the IMS standard is not very perfect. There is no commercial IMS network at present. Therefore, a large number of operators consider LTE application solutions that do not use IMS, or do not Adopt the LTE application scheme of IMS as transition. Among the many LTE transition solutions that do not use IMS, there is a solution called "LTE Fallback to CS (for voice services, fall back from the LTE network to the CS domain network for processing)". In this solution, LTE does not support VoIP ; For voice services, it is handled by the LTE Fallback to CS solution. Adopt the processing procedure of the voice paging of this scheme to comprise the following steps:

Step 1: UE camps on the LTE access network first, and the UE completes the location update of the GSM (Global System Mobile, Global System for Mobile Communications) or UMTS (Universal MobileTelecommunication System, Universal Mobile Communications System) network through the LTE access network;

Step 2: When the UE resides on the LTE access network, if there is GSM or UMTS voice paging, the MSC (Mobile Switch Center, mobile switching center or circuit domain core network) sends the paging message to the LTE network, and Send the paging message to the UE through the LTE access network;

Step 3: After receiving the voice paging from the LTE access network, the UE searches and transfers to the GSM or UMTS network, and then returns a paging response from the GSM or UMTS network and completes voice service access.

In this way, the LTE network mainly completes the PS (packet switch, packet switching) service access. When there is a voice service demand, the UE will use the LTE Fallback to CS solution to complete the voice service access.

It can be seen from the above processing process of voice information that before performing voice paging according to the "LTE Fallback to CS" scheme, it is necessary to be able to communicate in the GSM or UMTS core network (ie MSC) when the UE resides on the LTE access network. Or HLR (Home Location Register, local location register)) to complete location registration and location update, so that the UE can be correctly paged when there is voice paging.

In the process of implementing the present invention, the inventor found that there is no method for the UE to register the location area changes detected by the UE to Network2, which also makes it impossible to use the LTE Fallback to CS solution to complete voice service access.

Therefore, the problems of cross-network location registration and location update cannot be solved, and the problem of paging that may need to be performed after cross-network location registration cannot be solved.
