Abstract
The invention discloses a method and system for keeping multicast services continuous. The method comprises the steps that the situation that a new multicast group user accesses a WLAN through an access point (AP) is detected by wireless local area network (WLAN) equipment; internet group management protocol (IGMP) inquiry information is sent to the multicast group user by a network side to trigger the situation that the multicast group user sends IGMP report information; the IGPM report information fed back by the multicast group user is intercepted by the AP, and a multicast address and a mapped port of a multicast group where the multicast group user is located are added to a mapping table item of the AP by the AP; the AP continuously conducts multicast services on the multicast group user. Due to the adoption of the technical scheme of the method and system for keeping the multicast services continuous, the continuity of original multicast services can be kept when UE is transferred to a WLAN.
Description
Technical field
The present invention relates to field of mobile communication, particularly relate to a kind of continuous method and system of multicast service that keep.
Background technology
At present, WLAN (Wireless Local Area Networks is referred to as WLAN) development is rapid, and various WLAN terminals are popularized rapidly, and WLAN has become access network indispensable in people's daily life.In the prior art, no matter be enterprise network or carrier network, WLAN generally trends towards adopting centralized architecture, Fig. 1 is the schematic diagram of integral WLAN framework in the prior art, as shown in Figure 1, by Radio Access Controller (Access Controller is referred to as AC) configuration, a plurality of wireless access control point of control and management (Access Point, referred to as AP), AP adds WLAN and the wireless access service is provided by setting up link with AC.
Because what WLAN used is 2.4GHz industrial science medical treatment (Industrial Scientific Medical is referred to as ISM) frequency band and 5.8GHz frequency band.Use at present the more 2.4GHz frequency band that is based on 802.11b/g, only have 3 not overlapping channels, interface-free resources is especially valuable; Because 802.11 what adopt is positive acknowledgement mechanism, i.e. the frame of all transmission all must meet with a response, and has reduced actual efficiency of transmission in addition.
Along with the in recent years rapidly universal and explosive development of internet (Internet), the surge of portable terminal quantity, many new application have been produced at Internet, wherein much be the multimedia application of high bandwidth, such as network teleconference, network audio/video broadcasting, quotations on the stock market issue, multimedia remote education, moving advertising etc.These business have that flow is large, the characteristics of point-to-multipoint, if use unicast communication will bring rapid consumption and the network congestion problem of bandwidth.Use multicasting technology can effectively alleviate this type of business to network burden.
In order to make WLAN support multicasting technology, save the WLAN interface-free resources, the AP that disposes in WLAN must possess Internet Group Management Protocol and spy upon (Internet Group Management Protocol Snooping is referred to as IGMP Snooping) function.IGMP Snooping safeguards multicast address and VLAN (Virtual Local Area Network by the IGMP message of communicating by letter between listen for user and the router, referred to as VLAN) the corresponding relation of correspondence table, it is mapped as a VLAN with the active members of same multicast group, after receiving multicast packets, only transmit to the corresponding member of vlan of this multicast group.But, IGMP Snooping is passive listening, if new multicast group of its lower appearance of AP sends IGMP report (Report) before new multicast group membership, IGMP Snooping will be considered as its lower this multicast group that do not exist, also retransmitting multi-casting data not just.
Fig. 2 needs to keep the successional scene schematic diagram of multicast service in terminal use's transition process in the prior art, as shown in Figure 2, terminal use (User Equipment, referred to as UE) span into a movement, UE is first by access technology 1 (can be WLAN/WiMax/3G/LTE) access network, and add the multicast group, receive the multicast packets from multicast source.When UE migrates to wlan network, during access AP, the IGMP Snooping function of AP is not set up the mapping item of multicast address and mapped port in advance for UE, and AP does not transmit the multicast service from multicast source.
Because multicast router (Multicast Router, referred to as MR) the polling interval do not expire, UE temporarily can not receive the IGMP inquiry (Query) that multicast router sends, UE will not send IGMPReport, then the IGMP Snooping function of AP can't be known the multicast group at UE place, also just can't make up multicast group port mapping list item for UE.At this moment, UE must wait for that multicast router sends IGMP Query and triggers IGMP Report, but default polling interval is 125 seconds, so during this period of time, the multicast service of UE is with interrupt.
Summary of the invention
The invention provides a kind of continuous method and system of multicast service that keep, to solve the successional problem that under the situation of UE access WLAN, can't keep the UE multicast service in the prior art.
The invention provides a kind of continuous method of multicast service that keeps, comprising:
The WLAN wlan device detects new multicast group user by wireless access control point AP access WLAN;
Network side sends Internet Group Management Protocol IGMP apply for information to multicast group user, sends Internet Group Management Protocol IGMP report message to trigger multicast group user;
The IGMP report message of AP interception multicast group user feedback, and in the mapping item that adds multicast address and the mapped port of multicast group user place multicast group to self;
AP continues as multicast group user and carries out the multicast service service.
The present invention also provides a kind of continuous system of multicast service that keeps, and comprising: comprising: wireless access control point AP, and above-mentioned AP specifically comprises:
Detection module is for detection of whether new multicast group user being arranged by AP accessing WLAN network WLAN;
Sending module is used for sending Internet Group Management Protocol IGMP apply for information to multicast group user after defining new multicast group user and accessing WLAN, sends the IGMP report message to trigger multicast group user;
Blocking module is used for the IGMP report message of interception multicast group user feedback, and in the mapping item that adds multicast address and the mapped port of multicast group user place multicast group to self;
The multicast service module is used for continuing as multicast group user and carrying out the multicast service service after the mapping item that blocking module adds multicast address and the mapped port of multicast group user place multicast group to self.
Beneficial effect of the present invention is as follows:
By utilizing WLAN to the perception of UE, after detecting new multicast group user and accessing WLAN, send IGMP inquiry (Query) message to multicast group user (being UE) immediately.Multicast group user is after receiving IGMP Query message, feedback IGMP report (Report) message, thereby the IGMP of AP spies upon the information that (Snooping) function will record the subscriber-related multicast service of multicast group, and in the mapping item that multicast address and the mapped port of multicast group user place multicast group is added into self, multicast group user can continue to accept multicast service by AP, thereby solved the successional problem that under the situation of UE access WLAN, can't keep the UE multicast service in the prior art, the technical scheme of the embodiment of the invention does not need UE is changed, and only needs to do the continuity of changing slightly the original multicast service of maintenance just can realize that UE moves to WLAN the time at network side.
