Benefits of technology

The patent describes methods for providing both circuit-switched and packet-switched voice services to a mobile device in a service network. The methods involve determining which type of service to provide based on the capabilities of the mobile device and the network, and either handing over the service from one network to another or declining to provide a certain service if it is not an emergency. The technical effects of the patent include improved flexibility and reliability in providing voice services to mobile devices, and better utilization of network resources.

Problems solved by technology

When traversing network adapters, switches, routers and other network nodes, packets are buffered and queued, resulting in variable delay and throughput depending on the traffic load in the network.

Embodiment Construction

[0034]The following description is of the best-contemplated mode of carrying out the invention. This description is made for the purpose of illustrating the general principles of the invention and should not be taken in a limiting sense. The scope of the invention is best determined by reference to the appended claims. The 3GPP specifications are used to teach the spirit of the invention, and the invention is not limited thereto.

[0035]FIG. 1 is a block diagram illustrating a mobile communication environment according to an embodiment of the invention. The mobile communication environment 1 comprises a service network 13 that includes Global System of Mobile communication (GSM), General Packet Service (GPRS), and Universal Mobile Telecommunication System (UMTS) networks. The GSM or the GPRS network comprises a GSM Radio Access Network / GSM EDGE Radio Access Network (GRAN / GERAN) 10 and core network 14, in which the GRAN / GERAN 10 comprises a base transceiver station (BTS) 100 and a bas...

Abstract

Methods for handling PS and CS voice services between a mobile communication device and a service network are provided. The method comprises providing, by the service network, a first type of communication service to the mobile communication device and concurrently receiving, by the service network, a service request message to request for establishment of a second type of communication service, determining, by the service network, whether any type of communication service is an emergency service, and declining, by the service network, the type of communication service that is not the emergency service, wherein the service network only supports one type of communication service to the mobile communication device at one time.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This Application claims priority of U.S. Provisional application No. 61 / 350,752, filed on Jun. 2, 2010 and U.S. Provisional application No. 61 / 353,970, filed on Jun. 11, 2010, and the entirety of which is incorporated by reference herein.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to handling of communication services, and in particular relates to methods for handling Packet Switched (PS) and Circuit Switched (CS) voice services in a service network or a mobile communication device that only supports one type of communication at one time.[0004]2. Description of the Related Art[0005]In a typical mobile communications environment, a user equipment (UE) may communicate voice and / or data signals with one or more service networks via cellular stations of the service networks. The wireless communications between the UE and the service networks may be in compliance with various wireless technolog...
