Embodiment Construction

[0025] As described below, a coordinator switching method for a Medical Body Area Network (MBAN) is proposed. The Media Access Control (MAC) layer procedures and commands are defined for the Institute of Electrical and Electronics Engineers (IEEE) 802.15.4j standard as an example. However, the proposed scheme can also be implemented for other MBAN systems, such as IEEE 802.15.6 based systems, and within other higher layer protocols.

[0026] refer to figure 2 , the medical system 10 includes a medical body area network (MBAN) system 12 . MBAN system 12 is associated with patient 14 and is deployed to capture patient physiological data of patient 14 . Additionally, the MBAN system 12 includes one or more sensor devices 16 , 18 and a hub device 20 (ie, an initial coordinator) that communicate through an MBAN 22 of the MBAN system 12 . The MBAN 22 is a network (eg, a short-range wireless network) employing communication standards (eg, IEEE 802.15.6 and IEEE 802.15.4j) augment...

Abstract

Provided are a coordinator switching method and a corresponding device (20). One or more candidate coordinators (64) are identified for replacing the coordinator (20) of the medical body area network (MBAN) (22). The coordinator (20) is associated with one or more devices (16, 18) of the MBAN (22). One of the identified candidate coordinators (64) is selected as the destination coordinator. The destination coordinator (64) is requested to replace the coordinator (20) and the destination coordinator (64) allocates resources for the devices (16, 18). Acceptance of the request and data identifying resources allocated for the device (16, 18) are received from the destination coordinator (64). The devices (16, 18) are ordered to associate with the destination coordinator (64) using the allocated resources.

Description

technical field [0001] This application relates generally to wireless communications. The present application finds particular application in connection with, and will be described with particular reference to, Medical Body Area Networks (MBANs). It is to be understood, however, that the present application also applies to other usage scenarios and is not necessarily limited to the aforementioned applications. Background technique [0002] There is a general trend in the healthcare industry towards extending care services, such as patient monitoring, into the general ward and even beyond the boundaries of the physical hospital. Medical Body Area Network (MBAN) is one of the key enabling technologies for ubiquitous monitoring services. An MBAN is a wireless network of sensors around a patient for monitoring the patient's physiological data. Clinical benefits of MBAN include: expanded monitoring into currently unmonitored areas of care; improved healthcare workflow efficien...
