Problems solved by technology

[0011] For this roaming situation, existing technologies cannot guarantee business continuity
Users need to reacquire the service guide of the roaming area and reselect the programs they want to watch, which will greatly reduce the user experience

Embodiment 1

[0032] This embodiment provides a method for providing a multi-access selection mode in a service guide to realize access switching. If the user roams while watching the program, the terminal will select a new access segment to access the broadcast service according to the change of the service provider or the bearer network. During this process, the terminal initiates a service request on the roaming network in the background , There is no need to interrupt program viewing, maintaining business continuity.

[0033] In this embodiment, the service guide needs to be modified as follows: In addition to associating the access segment of the service at the home location of the terminal with the service segment, the access segment of the visited location is also associated with the service segment. The network identifier is added to the access slice, and different access networks are distinguished by different network identifiers. The access slice further corresponds to the session...

Embodiment 2

[0044] This embodiment provides a method for implementing access switching by providing multiple access options in a service guide. The difference from Embodiment 1 is that this embodiment is a service switching process in which the user moves from the first visited network to the home network or the second visited network during the process of receiving the multimedia broadcasting service in the first visited network.

[0045] Figure 4 It is a flowchart of this embodiment, and the implementation process of this embodiment is described in detail below in conjunction with FIG. 2:

[0046] Step S401, when the terminal moves to the junction with the second visited network while the first visited network (that is, the current service network) is receiving multimedia broadcasting, the terminal detects that the signal strength of the first visited network is less than the preset threshold value, Then the terminal initiates a query request to the first visited server through the in...

Embodiment 3

[0054] This embodiment provides another method for implementing access switching by providing multiple access options in the service guide. Different from Embodiments 1 and 2, the terminal in this embodiment does not need to initiate a request to the server through the interactive network to obtain the network identifier and access information of the target network, and the terminal can realize service switching through its own judgment.

[0055] The service guide of this embodiment also needs to be modified as follows: In addition to the association between the access segment of the service at the terminal's home location and the service segment, the access segment of the visited location is also associated with the service segment. The access segment further corresponds to the session description information, which provides specific access session parameters, such as encoding format, rate, etc., for receiving the multimedia broadcast service from different networks.

Abstract

The embodiment of the invention provides a control method of a multimedia broadcasting service, a system and a terminal thereof. The method comprises the following steps: a service instruction is received, and the service instruction comprises the access information of a plurality of networks supporting the multimedia broadcasting service; when network switching is required, the access information of a target network after switching is acquired according to the service instruction, and the multimedia broadcasting service continues to be received from the target network according to the accessinformation of the target network. The related switching processing is performed on a backstage by the method, thus users can complete smooth service switching while watching programs and can be unaware of service interruption, which improves the use experience of the users.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a control method, system and terminal of a multimedia broadcasting service. Background technique [0002] BCAST (Broadcast: broadcast protocol) is a concept of a mobile broadband digital broadcast / multicast service proposed by OMA (Open Mobile Architecture: Open Mobile Alliance). In terms of broadcasting, it includes the traditional one-to-many broadcasting method and multicast method, and considers connecting the original digital broadcasting services on the existing network architecture. OMA BCAST is dedicated to service discovery, electronic program / service guidance, billing, content protection, etc., formulates a specific service engine, and ensures that it is independent of the bearer layer. [0003] On September 10, 2004, companies such as Motorola, NEC, Nokia, Siemens, and Sony Ericsson jointly announced that they would cooperate in the mobile broadcast serv...
