Methods for requesting emergency bearer services for low priority devices, and apparatuses using the same. Veranlassen S einer Extended Service Request message bzw. Patent documents cited in the description. Non-patent literature cited in the description. Within nine months from the publication of the mention of 3ggpp grant of the European patent, any person may give notice to the European Patent Office of opposition to the European patent granted.

33gpp of opposition shall be filed in a written reasoned statement. It shall not be deemed to have been filed until the opposition fee has been paid. Generally, machines, nowadays, are equipped with computing processors and software to accommodate us with more intelligence-based services.

With the advancement of wireless communications, Machine Type Communication MTC has been developed to enable communications between remote machines for exchanging information and operating without human interaction.

As a result, the emergency bearer services will not be prioritized as they should be. In one scenario, a system information SI broadcast may include emergency services support information that conveys various emergency call network support levels and setup procedures.

The SI broadcast is decoded to retrieve system parameters used to process an emergency call. The SI broadcast may include a bitmap or at least one information element IEthat indicates the various emergency call network support levels. Further embodiments of the invention are claimed in the dependent claims. The mobile communication device comprises a wireless module and a controller module.

The wireless module performs wireless transmissions and receptions to and from a service network. This description is made for the purpose of illustrating the general principles of the invention and should not be taken in a limiting sense.

Note that the 3GPP specification s described herein are used to teach the spirit of the invention, and the invention is not limited thereto.

In the mobile communication environmentthe mobile communication device is configured for NAS signaling low priority, and is wirelessly connected to the service network for obtaining wireless services. The mobile communication device comprises a wireless module for performing the functionality of wireless transmissions and receptions to and from the service networkand a controller module for controlling the operation of the wireless module to carry out the communications with the service network in compliance with the communication protocol in use.

Taking the LTE technology for example, the communication protocol stack may generally comprise a NAS layer and an AS layer, wherein the NAS layer is a functional layer for providing the signaling and traffic between the mobile communication device and the core networkand the AS layer is a functional layer for providing the signaling and traffic between the mobile communication device and the access network To further clarify, the wireless module may be a Radio Frequency RF unit, and the controller module may be a general-purpose processor or a Micro-Control Unit MCU of a baseband unit.

The RF unit may receive RF wireless signals, convert the received RF wireless signals to baseband signals, which are processed by the baseband unit, or receive baseband signals from the baseband unit and convert the received baseband signals to Gs wireless signals, which are later transmitted. The RF unit may also contain multiple hardware devices to perform radio frequency conversion. For example, the RF unit may comprise a mixer to multiply the baseband signals with a carrier tx in the radio frequency of the mobile communication system, wherein the radio frequency may be MHz, MHz, or 2.

In this embodiment, the handling of the request for emergency bearer services takes place in the mobile communication device As shown in Fig. Specifically, the request comprises an RRC establishment cause which is set to “Emergency call”. Thus, with the setting of the establishment cause to “Emergency call”, both of the UE AS layer and the access network i.

In addition, with the setting of the service type to “packet service via S1 for emergency bearer services”, both of the UE NAS layer and the core network i. Thus, with the setting of the service type to “packet service via S1 for emergency bearer services”, both of the UE NAS layer and the core network i. In this embodiment, the method may be applied to any mobile communication device which is configured for NAS signaling low priority.

Thus, with the establishment cause indicating an emergency case, both of the AS layers at the UE side and the network side will prioritize the RRC connection establishment, so that the requested emergency bearer services may be further prioritized. Thus, with the setting of the service type, both of the NAS layers at the UE side and the network side will prioritize the requested emergency bearer services.

Those who are skilled in this technology can still make various alterations and modifications without departing from the scope of this invention.
