Another kind of situation is source node and destination node when accessing simultaneously the network of a plurality of operators, and the selection of via node should be considered the network condition of operator.For example, when source node has the wireless access way of the broadband access of China Telecom and China Mobile simultaneously, if destination node is when adopting the wireless access way of China Mobile, relay management entity preferably both sides all adopts the wireless access way of China Mobile, and selects suitable via node by the network condition of China Mobile.So just can avoid the cross operator route.
Particularly, when selecting via node, relay management entity 305 need to be considered a plurality of access waies of source node and destination node simultaneously, and comprehensive current network condition and the via node situation of core net.The factor that needs to consider includes but not limited to:
The access network speed of source or each access way of destination node, the features such as time delay
The right core net of each source or purpose access way interconnection situation, namely whether network is congested, and whether time delay meets the demands etc.
Core net active service quality test results
Whether via node is busy, overload or no available etc.
The carrier network preference policy
After having considered above factor, the relay route that the relay management entity is can be preferably suitable.Wherein, relay route refers to comprise source and the concrete access way of destination node, the routing information of the information of the via node that comprises in path corresponding to access way and order.The relay management entity can be included in available one or more relay route and return to the relay services requestor in the relay route information list.The prioritization information that in the relay route information list, can comprise each relay route.And, in relay route, can not comprise via node, namely in the situation that the relay management entity thinks that direct access path can meet the demands, the access way that comprises source and destination node in relay route, and do not comprise via node information.
