Problems solved by technology

However, in the design of how to carry out cellular mobile channel preemption for newly added calls that are only in single-cell coverage and handover calls that perform UVH handover to single-cell coverage, the PMV method does not consider the mandatory handover of UVH handover, and It is to give UVH handover calls the same right to compete and seize the cellular mobile channel as new cellular calls, and as a result, the call loss rate performance of UVH handover calls cannot be further improved

Embodiment Construction

[0022] The present invention will be further elaborated below in conjunction with the accompanying drawings and embodiments. The following examples do not limit the invention. Without departing from the spirit and scope of the inventive concept, changes and advantages that can be imagined by those skilled in the art are all included in the present invention.

[0023] figure 1 The structure of the cellular mobile network / WLAN interworking system is shown, which provides voice services for cellular mobile terminals and broadband data services for broadband data terminals (such as notebook computers) within the WLAN coverage area. Each cell channel capacity in embodiment simulation B It is 20BBUs (basic bandwidth unit), and the channel capacity of each WLAN coverage area is 54 BBUs. Channel Thresholds for Priority Cellular Mobile Channel Allocation , and 20BBUs, 19BBUs and 18 BBUs respectively. In order to meet the service QoS requirements, a single voice call needs to ...

Abstract

The invention discloses an uplink vertical handoff method for allocating and occupying priority channels between heterogeneous networks. The heterogeneous networks include a cellular mobile network and a wireless local area network. Based on the sufficient consideration of forcible handoff characteristic of uplink vertical handoff (UVH) and the requirement on voice business for real-time property, the uplink vertical handoff method for allocating and occupying cellular mobile channels on the basis of priority is provided by defining the priorities of UVH calls and newly-added cellular calls having cellular mobile channel allocating and occupying requirements in a single-cellular coverage zone. The method disclosed by the invention has the advantage of further improving the loss rate performance of UVH calls having the forcible handoff characteristic while maintaining high utilization rate of the cellular mobile channels of the system and lower blocking rate performance of the newly-added cellular calls, thereby effectively ensuring higher communication service quality of intercommunication system businesses of the cellular mobile network and the Wireless Local Area Network (WLAN).

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to an uplink vertical switching method for priority channel allocation and preemption among heterogeneous networks. Background technique [0002] At present, with the continuous growth of people's demand for mobile access services, the next-generation wireless communication technology is developing towards the direction of realizing heterogeneous wireless network intercommunication. Cellular mobile network and wireless local area network (WLAN) are two major wireless communication networks in modern wireless communication. The cellular mobile network is characterized by large coverage and low bandwidth, while WLAN is characterized by small coverage and high bandwidth. The intercommunication between the cellular mobile network and WLAN can make the advantages of the two complement each other and enhance the quality of service (QoS) of the services provided. [0003] ...
