Problems solved by technology

[0015] In short, the solution is to let the OLT encrypt the data flow of the mobile data service using complex encryption technologies such as IKE, and pass the key to those ONTs connected to the femtocell device in a confidential way. Therefore, Only ONTs serving femtocell devices can decrypt encrypted data streams, which increases the di

Embodiment Construction

[0047] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. Those skilled in the art understand that, although the following description will mainly be made in conjunction with a specific example of multicast, this should not be interpreted as limiting the scope of protection of the present invention to multicast at any time. In fact, the protection scope of the present invention includes but not limited to multicast and broadcast mobile data services, as defined in the appended claims. Wherein, for the convenience of comparing the present invention with the prior art, still combine figure 1 In the network structure shown, it should be understood that figure 1 The signal flow shown in FIG. 2 only corresponds to the prior art, and the following description only borrows the various devices therein.

[0048] First, the OLT needs to determine the receiving authority of the mobile data service on the user s...

Abstract

The invention discloses a method and a device for controlling the forwarding of mobile broadcast and multicast services in a passive optical network. The main idea of the invention is: establishing a mapping relationship between the user port of ONT and a receiving authority of a mobile data service at OLT, namely, determining a mapping relationship between an IP address of femto equipment and a user port (mark) of the ONT in an address distribution flow under a DHCP protocol; and on this basis, the OLT is capable of obtaining a mapping relationship between a receiving authority of a mobile data service of each mobile terminal and an IP address of a femto equipment connected with corresponding mobile terminal from a user management server maintained by a mobile network operator based on an agreement between the mobile network operator and the fixed network operator, and finally establishing the corresponding relationship between the user port and the receiving authority indirectly. Obviously, the way is more flexible and accurate than the way of distributing a static mapping table by the OLT.

Description

technical field [0001] The present invention relates to the forwarding of mobile multicast and broadcast services in passive optical network, in particular to the method and device for controlling the forwarding of multicast and broadcast services. Background technique [0002] Recently, femtocell technology has attracted more and more attention from mobile service providers, thanks to its excellent performance in saving backhaul overhead, helping to expand indoor coverage, and improving service quality. At the same time, Gigabit Passive Optical Network (GPON) has gradually developed into an advantageous substitute for Digital Subscriber Line (DSL) due to the high capacity of fiber-to-users for local network access. Therefore, the femtocellular network using GPON backhaul has become a trend in this field. [0003] The mobile data service represented by mobile TV is one of the services that mobile operators value very much. In order to realize this kind of service, the way ...
