[0114] Refer below Figure 5 and Figure 6 This embodiment will be described. The network resource scheduling method according to this embodiment is applicable to the situation that the mobile terminal is turned on or switched. On the basis of the first embodiment, when the radio resource controller detects that there is a power-on event or a type switching event When using a mobile terminal, perform the following steps:

[0115] Step 7, the radio resource controller periodically detects whether there is a mobile terminal that has a power-on event or a type switching event;

[0116] Step 8, if the radio resource controller determines that there is a mobile terminal that has a power-on event or a type switching event, forwarding sublayer information of the network coverage area where the mobile terminal that has a power-on event or a type switching event is located sent to the (corresponding) mobile terminal where a power-on event or a type switching event occurs; and

[0127] Refer below Figure 7 This embodiment will be described. In this embodiment, the scheduling methods of the foregoing embodiments can still be used. The main difference between this embodiment and the foregoing embodiments is that this embodiment has innovatively improved the congestion handling mechanism. It should be noted that the method in this embodiment can be implemented in combination with any embodiment of the present invention.

[0128] The traditional technical solution believes that when congestion occurs, the routing node should implement a priority discarding strategy, that is, first discard low-priority high-level data packets, and then discard high-priority low-level data packets. In this way, although the transmission of low-level data packets is protected, this traditional data packet discarding strategy cannot quickly solve the congestion, which will easily lead to the maintenance of the overall network performance at a low level.

Abstract

The invention discloses a network resource scheduling method in a heterogeneous network and a wireless resource controller. The network resource scheduling method is suitable for multimedia data transmission in the heterogeneous network and comprises the following steps: each mobile terminal measures and determines the respective expected binding number of terminal sublayers every other first schedule time, the respective expected binding number of terminal sublayers and the type of the mobile terminal are reported, the wireless resource controller determines the forwarding sublayer information of the network coverage area every other second schedule time according to the reported message of the mobile terminal, and sends the forwarding sublayer information of the network covering area where the mobile terminal is located to the mobile terminal; the mobile terminal determines the binding number of terminal sublayers according to the type of the mobile terminal and the received forwarding sublayer information to decode and play back the multimedia data according to the determined binding number of terminal sublayers, wherein the forwarding sublayer information is the information relevant to the data required to be forwarded in the network coverage area. The network resource scheduling method ensures that the network resources can be fully utilized.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to wireless resource scheduling for layered stream transmission under heterogeneous networks, and especially to joint wireless resource scheduling under heterogeneous networks integrating LTE and WLAN networks. Background technique [0002] A notable feature of the next generation wireless network is the heterogeneity of wireless networks and mobile terminals (referred to as terminals or receivers). Heterogeneity refers to the mutual integration of different rate links or different access technologies, and the collaborative work of terminals with different receiving capabilities. For example, in 3GPP Long Term Evolution (LTE, Long Term Evolution), a technical solution is proposed to couple LTE and 802.11 wireless local area network (WLAN) to provide users with broadband video data services. Existing cellular network technologies such as CDMA2000 and TD-SCDMA ...
