Description
Technical field
The present invention relates to the communications field, in particular to a kind of state indication method, core net (Core Net abbreviates CN as) and radio network controller (Radio Network Controller abbreviates RNC as).
Background technology
Third generation collaborative project tissue (The 3rd Generation Partnership Project, abbreviate 3GPP as) networking mode of IU FLEX (IU is meant the interface of CN and RNC) proposed, in same CN territory, for example, circuit switching (Circuit Switch, abbreviate CS as) territory, or packet switching (Packet Switch, abbreviate PS as) territory, a plurality of CN manage as a pond (POOL), and each CN in the same POOL can manage the identical a plurality of RNC in the same zone, similarly, each RNC in this zone can link to each other with each interior CN of POOL simultaneously, and this zone is made of a plurality of lane place usually.Adopt IU FLEX networking can make interior each CN of same POOL carry out load sharing, strengthen the disaster tolerance of CN system, after a CN broke down, RNC can be the service selection of subsequent user equipment (User Equipment abbreviates UE as) to other normal CN of POOL.
Each CN in the POOL is by network resource identifier (Network Resource Identifier, abbreviate NRI as) distinguish, RNC safeguards the corresponding relation of each CN and NRI, CN upgrades or distributes to when carrying out business circuit domain user temporary mobile subscriber identity (the Temporary Mobile Subscriber Identity of UE in the UE position, abbreviate TMSI as) or packet domain user temporary mobile subscriber identity (Packet Temperate Mobile Subscription Identity, abbreviate P-TMSI as), wherein, the value represented to 23 bits of the 14th bit of TMSI (being made up of 32 bits) or P-TMSI (being made up of 32 bits) is exactly the NRI of this CN correspondence.
When UE and CN were mutual, RNC found corresponding CN to handle according to the NRI information of carrying in the UE message.IU FLEX has also introduced load offloading functions (off-loaded), with the CS territory is example, when certain CN in the POOL need load unloading, after CN receives the location area updating or Routing Area Update message of UE within a certain period of time, can distribute to the Null-NRI and Non band of position coding (the Location Area Code of definition in this UE mobile network, abbreviate LAC as), UE initiates lane place or Routing Area Update message after receiving this information again, and RNC sends to other CN to the location area updating message of UE according to Null-NRI and the Non LAC information that UE carries; For the current UE that is carrying out business, CN also can distribute to Null-NRI of this UE and Non LAC after service ending, UE initiates lane place or Routing Area Update message after receiving this message again, and RNC sends to other CN to the location area updating message of UE according to Null-NRI and the Non LAC information that UE carries; When carrying IMSI or IMEI information when upgrading for the UE position, RNC guarantees to select outside this CN a CN to send location update message.
The load offloading functions can be supported the flexible maintenance of operator for the CN network element, for example, by utilizing the load offloading functions of CN, can upgrade one by one and can not cause conversation loss or unusual in the net CN in the POOL when the CN edition upgrading.But being safeguarded directly by manual operation of the load unloaded state of 3GPP suggestion CN disposed, and RNC does not have the load unloaded state that direct approach is known CN, can only dispose by artificial Operation and Maintenance yet.A common CN manages several RNC and is connected, and the method for this human configuration can not guarantee the correctness and the consistency of configuration information fully.
