Embodiment 1

[0063] User A has a personal network, including a personal network gateway and four personal network devices. The networking diagram is as follows image 3 As shown, the personal network device 1 and the personal network device 4 support video services. User A is using the personal network device 1 to use the VOD service through the personal network gateway. At this time, the battery of the personal network device 1 is low. In the above scenario of this embodiment, the seamless handover process includes the following steps:

[0064] Step 201: User A uses the personal network device 1 to send a service switching request to the personal network gateway, which contains the description information of the VOD service.

[0065] Step 202: After receiving the switching request, the PN gateway judges to select the PN device 4 as the new PN device after switching according to the description information of the VOD service.

[0066] Step 203: The PN gateway sends a service switching request to...

Embodiment 2

[0078] User A has a personal network, including a personal network gateway and four personal network devices. The networking diagram is as follows Figure 4 As shown, the personal network device 1, the personal network device 2, and the personal network device 4 support video services. User A is using the personal network device 1 to use the VOD service through the personal network gateway, and the personal network device 1 needs to leave the personal network at this time. In the above scenario of this embodiment, the seamless handover process includes the following steps:

[0079] Step 301: User A uses the personal network device 1 to send a service switching request to the personal network gateway, which contains the description information of the video-on-demand service, and the description information of the video-on-demand service includes synchronization information for service synchronization, such as current broadcast Time and so on.

[0080] Step 302: After receiving the...

Embodiment 3

[0092] User A has a personal network, including a personal network gateway and four personal network devices. The networking diagram is as follows image 3 As shown, the personal network device 1 and the personal network device 4 support video services. User A is using the personal network device 1 to use the VOD service through the personal network gateway. At this time, the battery of the personal network device 1 is low. In the above scenario of this embodiment, the seamless handover process includes the following steps:

[0093] Step 401: User A uses the personal network device 1 to send a service switching request to the personal network gateway, which contains the description information of the VOD service.

[0094] Step 402: After receiving the switching request, the PN gateway judges to select the PN device 4 as the new PN device after the switch according to the description information of the VOD service.

[0095] Step 403: The PN gateway sends a service switching request t...

Abstract

The invention discloses a seamless switching method based on a personal area network. The seamless switching method based on the personal area network comprises the following steps of: selecting target personal area network equipment after a personal area network gateway receives a trigger request of business switching; and performing business switching between original personal area network equipment and the target personal area network equipment after the target personal area network equipment agrees the business switching. The invention also discloses a seamless switching device based on the personal area network. The seamless switching device based on the personal area network comprises a target selecting unit and a business switching unit, wherein the target selecting unit is used for selecting the target personal area network equipment, and the business switching unit is used for performing the business switching between the original personal area network equipment and the target personal area network equipment after the target personal area network equipment agrees the business switching. By adopting the seamless switching method and device based on the personal area network disclosed by the invention, the problem on how to realize the seamless switching of business in the personal area network when the business switching is required can be solved effectively.

Description

Technical field [0001] The invention relates to a handover technology based on a personal network, in particular to a seamless handover method and device based on a personal network. Background technique [0002] With the development of science and technology, people have more and more personal devices, such as mobile phones, notebook computers, PDAs, MP3, MP4, etc., and the capabilities of these devices are getting stronger and stronger, and most of them have the ability to communicate over short distances. Therefore, people increasingly hope to connect these devices around them to form a personal area network (PN) to share each other's resources and capabilities. [0003] Such as figure 1 Shown is a schematic diagram of the networking among various devices in a PN. The PN includes: personal network equipment, personal network gateway, and personal network server. The networking relationship between them is: personal network consists of personal network gateway, personal network e...
