Description

Method and terminal for realizing multi-system collaborative service shunting network selection

Technical Field

The invention relates to a wireless communication technology, in particular to a method and a terminal for realizing multi-system collaborative service shunting network selection of LTE, WLAN and 3G.

Background

With the continuous evolution of mobile networks and the wide deployment of Wireless Local Area Network (WLAN) hotspots, on one hand, networks such as 3G (including HRPD, UMTS, etc.), Long Term Evolution (LTE), WLAN, etc. coexist for a long time in practical applications, and a radio access network presents a development trend of isomerization; on the other hand, the popularization and development of intelligent terminals enable the number of mobile internet users and data traffic to correspondingly increase continuously, and the technical progress enables the terminals to have the capacity of accessing a plurality of access networks. Therefore, it is a concern to ensure that the user uses the most suitable access network at the proper time and place to ensure that the user obtains the optimal network application experience and to ensure that the network resources are reasonably utilized.

In the prior art, when LTE, third generation mobile communication technology (3G) and WLAN networks coexist, traffic steering and offloading of a terminal between LTE and 3G are triggered by an LTE base station or a 3G base station, and traffic steering and offloading between LTE and WLAN, or 3G and WLAN, are triggered by the terminal itself. At present, LTE-to-3G traffic and offloading triggered by an LTE base station and 3G-to-LTE traffic and offloading triggered by a 3G base station do not take into account the network state of a WLAN; and the UE-triggered traffic steering and offloading between LTE and WLAN or 3G and WLAN does not consider the network state of 3G or LTE either. Since the service migration triggering belongs to different control points and the existing cooperative processing mechanism among various systems does not exist, the effective utilization of wireless network resources is influenced, the optimal network selection cannot be carried out according to the network resource conditions, and the network access experience of users is influenced.

Taking LTE-dominated heterogeneous networks with coexistence or overlapping coverage of LTE, 3G and WLAN as an example, when LTE has an offloading requirement, the radio access traffic of the UE may be migrated to 3G or WLAN. The LTE base station can configure the terminal to perform 3G measurement, and if the 3G signal condition and the load condition meet the conditions, the LTE base station can trigger the terminal to be migrated or redirected to 3G from LTE; since the terminal is in the coverage of the WLAN at the same time, the terminal can trigger the service migration to the WLAN according to the WLAN network state (such as signal, load, and resource situation), the operator policy (such as ANDSF policy), and the user selection tendency. Fig. 1 is a schematic diagram of a conventional offloading decision conflict, as shown in fig. 1, since offloading decision points of a WLAN and a 3G are different and other network states are not considered in offloading decision, an offloading decision of LTE and an offloading decision and offloading operation of a terminal may cause a conflict, which may result in that migration or redirection to the 3G triggered by LTE cannot achieve the purpose of offloading or improving user experience; if the UE is adopted to migrate by itself, the WLAN network has limited capacity, and if a large number of UEs are flooded, the WLAN user experience is easy to deteriorate.

Based on the fact that the existing 3G network can provide better user experience in the aspect of meeting the common internet surfing requirements of users, a multi-mode collaborative network selection supporting LTE and 3G, WLAN is needed to provide better network application experience for users and reasonable network resource use of various disciplines. Similarly, when the 3G network has an offloading requirement, the traffic may be offloaded to LTE or WLAN, and a decision conflict affecting user experience still exists, so that the best quality wireless network resource cannot be provided.

In summary, currently, a multi-system cooperative network selection method is lacking when service migration is performed between networks of 3G, LTE, and WLAN, which affects users to fully utilize network resources in the existing environment and realizes good access of wireless services.
