Description
Technical field
The present invention relates to the communication technology between the base station, refer to a kind of method that improves communication speed between base stations especially.
Background of invention
In mobile communication system, particularly in 3-G (Generation Three mobile communication system), in the general base station (NodeB) margin signal of certain sub-district (Cell) a little less than, the signal of other sub-district around utilizing simultaneously, by the diversity on the space, can improve the performance of subscriber equipment (UE, User Equipment).Soft handover in the mobile communication, cell update and gravity treatment, all the fringe region with several sub-districts has relation.When soft handover, cell update and gravity treatment took place, communication contact can take place with several sub-districts in UE simultaneously, and these several sub-districts are called as Active Set; Simultaneously, also have some sub-districts since the signal strength signal intensity that receives UE not a little less than, prepare at any time and the UE communication, these sub-districts are called as Candidate Set.
Traditional wireless access network is the tree structure that is made of radio network controller (RNC, Radio Network Control-ler) and NodeB, and in this structure, the contact between each NodeB is coordinated by RNC.In RNC, be provided with information such as numbering that a database is used to store these all NodeB of RNC subordinate, address, these information are normally when NodeB and RNC set up and reshuffle, dispose by OMC operation and maintenance centre (OMC, Operation andMaintenance Center) platform by network planning engineer.When soft handover takes place when, be to notify the sub-district among the relevant NodeB whether to be activated by RNC, whether be in Candidate Set or the like, by the communication relation that the centralized control of RNC is come each sub-district of united and coordinating and UE, this traditional controlling mechanism will certainly increase the transmission of signaling and the time delay of processing and data.
Evolution along with wireless network architecture, to introduce Internet Protocol (IP) transmission in the Radio Access Network, its basic networking structure as shown in Figure 1, to an IP network between RNC and the NodeB, RNC and NodeB are connected in the IP network by edge router (ER) respectively, a RNC can support a plurality of NodeB, and a NodeB also can connect a plurality of RNC.The appearance of complete IP network structure, make NodeB function from strength to strength, the IuNB interface of its direct communication will appear supporting between NodeB and NodeB, by the IuNB interface, can avoid RNC between the NodeB, directly set up communication fast, thereby reduce the data latency issues brought by Iub interface communication between RNC and the NodeB, also reduced the transmission and the processing of signaling.
In above-mentioned new wireless network architecture, when soft handover, cell update and gravity treatment took place, NodeB need know the situation of NodeB under several sub-districts relevant with current UE, and communication with it.Therefore, NodeB must know the information such as sign, address of NodeB under the own peripheral edge region neighbor cell in advance.But, owing to have only information such as the numbering that stores in the database of RNC about all NodeB of subordinate, address at present, NodeB can only obtain corresponding information from RNC when soft handover, cell update and reselection operation take place, so, can bring very big time delay, and then influence the treatment effeciency of whole system.

Embodiment
The present invention is further described in more detail below in conjunction with drawings and the specific embodiments.
In IP Radio Access Network architecture, realize intercommunication by the IuNB interface between all NodeB, when communicating by letter between NodeB, address IP available address+User Datagram Protoco (UDP) (UDP) port numbers of each NodeB identifies.So, for each sub-district of NodeB subordinate, also need increase the Cell Identity CI that is used for identifying cells, therefore, an attribute is set in NodeB, in order to writing down the information of each sub-district, the data structure of this attribute comprises the udp port number of the IP address of Cell Identity CI, affiliated NodeB and affiliated NodeB as shown in Figure 2.
Thought of the present invention is set up a sub-district neighbouring relations database respectively exactly in RNC and NodeB, be used for writing down the relation between all sub-districts and neighbor cell thereof.Wherein, the sub-district neighbouring relations database of being built in RNC is a database master basis, comprise the neighbouring relations between each sub-district among all NodeB of subordinate, because the neighbor cell of general each sub-district can be above 8, so at each selected object sub-district, the structure of its database comprises the attribute of an object sub-district and the attribute of eight neighbor cells as shown in Figure 3, and each attribute includes the IP address of Cell Identity CI, affiliated NodeB and udp port number three parts of affiliated NodeB.The sub-district neighbouring relations database of being built in NodeB is a Database Replica, comprises the neighbouring relations between all sub-districts of this NodeB subordinate, and the structure of its database equally as shown in Figure 3.When communicating between the NodeB, current NodeB only needs can select the purpose sub-district from the sub-district neighbouring relations database of oneself, and obtains the attribute information of this neighbor cell, and then finishes follow-up operation.And the sub-district neighbouring relations database among the RNC can be used as a kind of backup, when adjacent cell information that certain NodeB need be correlated with, can obtain from the sub-district neighbouring relations database of RNC at any time.And, when data record need be upgraded, only need to reconfigure database among the RNC by the OMC platform, send to all relevant NodeB by RNC then and upgrade configuration information, once upgrade configuration operation and need not on each relevant NodeB, do, realize more simple and convenient.
The signaling process of setting up and reconfigure sub-district neighbouring relations database is as shown in Figure 4:
When RNC, NodeB and cell initial are set up, as initial foundation shown in the part among Fig. 4, with RNC1 is example, and the OMC platform sends RNC sub-district adjacent data to RNC1 and sets up request RNC CellNeighbor Data Setup Request message, and the sub-district neighbouring relations database among the RNC is set up in request; RNC1 carries out corresponding operation, after setting up database, return RNC sub-district adjacent data to OMC and set up successfully (or failure) RNC Cell Neighbor Data Setup Success (or Failure) message, expression sub-district neighbouring relations database is set up successfully or is failed, and needs request again if set up failure.After the sub-district neighbouring relations database among the RNC is built up, RNC1 can send NodeB sub-district adjacent reconfiguration request NodeB Cell Neighbor Reconfiguration Request message to NodeB, this moment is not because base station side is also set up sub-district neighbouring relations database, after receiving this message, the sub-district neighbouring relations database of oneself can be set up in the base station, afterwards, return the adjacent report NodeB Cell Neighbor Reconfiguration Report message of reshuffling in NodeB sub-district to RNC1, wherein carry the information that expression is set up successfully or failed, need request again if set up failure.
When the base station physical configuration changes, for example: when newly-increased base station or newly-increased sub-district, as reshuffling among Fig. 4 shown in the part, with RNC1 is example, the OMC platform sends RNC sub-district adjacent data reconfiguration request RNC Cell Neighbor Data Reconfiguration Request message to RNC1, request reconfigures the sub-district neighbouring relations database among the RNC, upgrades the data in the neighbouring relations database of sub-district that is:; After RNC1 handles accordingly, return RNC sub-district adjacent data to OMC and reshuffle report RNC Cell Neighbor Data Reconfiguration Report message, wherein carry the information of expression configuration successful or failure.If configuration failure needs request again, if configuration successful, RNC1 NodeB under all sub-districts in its sub-district neighbouring relations database then, send a NodeB sub-district adjacent reconfiguration request NodeB Cell Neighbor Reconfiguration Request message respectively, the recorded content of sub-district neighbouring relations database among the NodeB is upgraded in request, NodeB handles accordingly, if do not set up the sub-district neighbouring relations database of oneself among certain NodeB as yet, then NodeB sets up new sub-district neighbouring relations database, then, return the adjacent report NodeB Cell Neighbor Reconfiguration Report message of reshuffling in NodeB sub-district to RNC1, wherein carry the information of expression configuration successful or failure, if configuration failure needs request again.
When certain RNC or its subordinate's NodeB or this NodeB subordinate's cell configuration change, have influence on when sub-district neighbouring relations database changes among the RNC under the neighbor cell of object sub-district, the RNC that changes can reconfigure the data in the neighbouring relations database of influenced RNC sub-district automatically.Suppose that the RNC that changes is RNC1, affected sub-district belongs to RNC2, then reshuffle automatically shown in other RNC part as Fig. 4, send sub-district adjacent data reconfiguration request RR Cell Neighbor Data Reconfiguration Request message between RNC by RNC1 to RNC2, after receiving, finishes RNC2 reshuffling of relevant information in the neighbouring relations database of own sub-district, return between RNC the sub-district adjacent data to RNC1 then and reshuffle report RR Cell Neighbor DataReconfiguration Report message, wherein, carry the information of expression configuration successful or failure.If configuration failure needs request again, if reshuffle successfully, then RNC2 will issue NodeB sub-district adjacent reconfiguration request NodeB Cell NeighborReconfiguration Request message by the NodeB under related cell, carry out same reconfiguration operation, after NodeB reconfigures the sub-district neighbouring relations database of oneself, return the adjacent report NodeBCell Neighbor Reconfiguration Report message of reshuffling in NodeB sub-district equally and give RNC2, wherein carry the information of expression configuration successful or failure, if configuration failure needs request again.
Usually, the udp port resource of NodeB can be used after setting up always, but in some cases, NodeB can discharge some permanent no udp port resources, waits the time spent again, and application distributes new udp port resource again.When above-mentioned incident takes place, NodeB can send RNC sub-district adjacent data reconfiguration request RNC Cell Neighbor Data Reconfiguration Request message to RNC, request reconfigures the udp port number of revising respective cell in the neighbouring relations database of RNC sub-district, after RNC makes corresponding modify, return RNC sub-district adjacent data to NodeB and reshuffle report RNCCell Neighbor Data Reconfiguration Report, wherein carry the information of representing successfully or failing, if the failure would need to ask again.
