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. like 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 LTE ...

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 invention provides a mobility management method and a terminal, and the method comprises the steps: determining whether the terminal is located in an available position range for a long term evolution (LTE) and wireless local area network (WLAN) fusion LWA service; when the terminal is located in an available position range for the LWA service, initiating establishment of an LWA communicationlink; the LWA communication link includes at least one of a long term evolution (LTE) communication link and a wireless fidelity (Wifi) communication link. According to the scheme, whether the terminal is located in an available position range of an LWA (Long Term Evolution) service and a WLAN (Wireless Local Area Network) fusion LWA (Local Area Network) service or not is confirmed; when the terminal is located in an available position range for the LWA service, initiating establishment of an LWA communication link; wherein the LWA communication link comprises at least one of a long term evolution LTE communication link and a wireless fidelity Wifi communication link. Therefore, the establishment failure process of the LWA service transmission can be avoided, the signaling overhead and theLWA link establishment delay are reduced, and the network performance is improved; and realizing mobility management of the 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...
