Description
Technical field
The present invention relates to the mobile communication technology field, especially a kind of in each network element of heterogeneous network the update method and the system of the network information.
Background technology
Along with the development of mobile communication technology, present mobile communications network has developed to microcellulor and macrocellular, may intersect covering between these honeycombs mutually, switches just may take place between dissimilar media networks.But under original wireless communication technology condition, the mobile subscriber can not roam between different wireless access technologys and switch.In order to solve the process of this roaming and switching, occur a kind of media-independent now and switched (Media Independent Handover, be called for short MIH) technology, for the mobile subscriber provides handoff procedure between the different media networks, by supporting the switching between the different media networks to strengthen the experience of user to mobile device, make mobile device when internetwork roaming, can select best network connection type and seamless switching speech channel automatically, and need not user intervention.
This MIH technology has been introduced a kind of professional successional framework that switches of guaranteeing between the different media networks, and seamlessness and the continuity of this framework in order to realize switching realized one group of handoff functionality collection between network element.These handoff functionality collection of configuration have just formed a new protocol layer in the mobility management protocol stack of network element, are referred to as the MIH protocol layer, are exactly the link layer of various access networks under the MIH layer.The major function of MIH layer be exactly by Event Service, command service and information service that provide with handoff functionality media-independent, make the processing of upper-layer protocol not rely on the concrete feature and the characteristic of terminal and wireless network.This independence is to provide unified interface to realize by the lower-layer protocols in the mobility management protocol stack to the upper strata.
The MIH agreement mainly comprises following several basic network entity: mobile node (Mobile Node is called for short MN), i.e. communication node from a link to another one link change attachment point; Attachment point (Point of Attachment is called for short PoA) be positioned at the destination node of layer two link (MAC layer, i.e. MAC layer) at network side, and the another one destination node of layer two link is MN; MIH service point (MIH Point of Service, be called for short MIH PoS), i.e. the MIH entity of network side can be directly and the mutual MIH message of MN with MIH function.Wherein, the position of MIH PoS is unfixed, can change according to the deployment scenario of operator and special MIH structure.A MIH PoS can be positioned at or be close on the PoA node of access network, also can be positioned at the inside of access network or core network.
Fig. 1 is for being triggered, had the typical switching flow of a plurality of candidate network by terminal, this switching flow is based on the MIH agreement.As shown in Figure 1:
The service point Serving PoS of step 102, current service network is according to the candidate chains line, and the PoS under candidate's link sends the resource query request.Under PoS and scene that PoA separates, because the link in candidate's list of link may belong to different PoS, Serving PoS may send resource inquiry information to a plurality of PoS, and obtaining to return to MN after the relevant information, carries out handover decisions for MN.
By the information service that the MIH layer provides, MN can obtain the information of other the available access network in this geographic range when trans-network roaming.Various information element (Information Element is called for short IE) is supported in information service, comprises network list, network provider, PoA address, charge information etc.The IE that information service provides mainly leaves information server (the Information Server in the network in, be called for short IS) in, mutual by with IS of MN or service network can obtain the information of neighbours' access network and attachment point PoA on every side in advance, thereby carry out the selection of candidate network.
Existing MIH agreement only is applicable to the situation that network topological information does not change.When heterogeneous network information changes, if the relevant network element in the service network can not obtain update notification in time, come the network information that changes is upgraded, MN or service network may still adopt the network information of not upgrading and the processing that leads to errors when switching, thereby can't finish switching flow.
Summary of the invention
The purpose of embodiments of the invention is to propose a kind of network information update method and system, in the time of can the network information changes in heterogeneous network, in time the network information of related network elements storage in the heterogeneous network be upgraded.
For achieving the above object, embodiments of the invention provide a kind of network information update method, comprising:
The request that the requirement topology that the service point that information server reception network topological information changes sends is upgraded;
Described information server upgrades the network topological information of self storing according to the request that receives.
For achieving the above object, embodiments of the invention provide another kind of network information update method, comprising:
