example 1

[0228] This program includes:

[0229] (1) The UE receives the location information broadcast by the LTE base station or the wifi AP.

[0230] This solution is applicable to various LTE and wifi aggregation architectures. The first transmission link is established between the terminal device and the LWA gateway device through LTE, and the second transmission link is established through WLAN. The network device can pass through the LTE network through the first transmission link. The user equipment data can be sent to the terminal, and the user equipment data can also be sent to the terminal through WiFi, which realizes the aggregation of user data streams on the network side. Such as Figure 4 , in the aggregated LTE and wifi service architecture on the core network, the LWA gateway function is located upstream of the PGW function of the LTE core network, and UE data is distributed from the LWA gateway device to different transmission links of the UE, that is, via the first L...

example 2

[0258] This program includes:

[0259] (1) The UE receives the location information broadcast by the LTE base station or the wifi AP.

[0260] The UE supporting LWA aggregation can receive the cell location-related information indicated in the LTE cell broadcast information through the LTE air interface, that is, the first location information, for example, the cell identifier (closed service group identifier CSG-ID or evolved unified land wireless access Network E-UTRAN cell global identifier ECGI), network identifier (public land mobile network identifier PLMN-ID) or tracking location area (TAC), etc., the UE can read the AP location-related information in the wifi cell broadcast through the wifi wireless interface, That is, the second location information, such as a service set identifier SSID or a basic service set identifier BSSID.

[0261] (2) The UE matches the location corresponding to the received location information with the pre-stored available location range for ...

Abstract

The present invention provides a mobility management method and a terminal, wherein the mobility management method includes: confirming whether the terminal is located within the range of available locations for long-term evolution LTE and wireless local area network (WLAN) integrated LWA services; When within the location range, initiate the establishment of an LWA communication link; the LWA communication link includes at least one of a Long Term Evolution LTE communication link and a Wireless Fidelity Wifi communication link. This solution confirms whether the terminal is located within the available location range for the long-term evolution LTE and wireless local area network WLAN fusion LWA service; when the terminal is located within the available location range for the LWA service, initiates the establishment of the LWA communication link; wherein, the LWA communication link The path includes at least one of a Long Term Evolution LTE communication link and a Wireless Fidelity Wifi communication link; thus, the LWA service transmission establishment failure process can be avoided, signaling overhead and LWA link establishment delay can be reduced, and network performance can be improved; Realize mobility management of UE.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a mobility management method and a terminal. Background technique [0002] LTE (Long-Term Evolution, long-term evolution) and WiFi (WIreless-Fidelity, wireless fidelity) aggregation (LWA) technology refers to supporting UE (User Equipment, user equipment) to receive and send IP (Internet Protocol, 3GPP currently supports a variety of LTE and WiFi aggregation data technologies, which are divided into LTE and WiFi aggregation technologies at the LTE core network and radio access network (RAN, Radio Access Network) level LTE and WLAN (Wireless LAN, wireless local area network) aggregation technology. In the aggregation of LTE and WiFi technology at the LTE core network, there are two network architectures: trusted access and untrusted access, which support WLAN to connect to the core network PGW (packet data Network PDN gateway), in the untrusted mode, UE establishe...
