Transmission network is configured according to the IP of control net for its configuration, and accepts the control net its route is intervened management.
Realize Signalling exchange in the center base station, the internal memory between the portable terminal in the transmission network that application program can be in control net.
In the embodiment of the invention, the GSM/GPRS network needs to obtain the relevant information of the portable terminal in the Ad-Hoc network, so that be Ad-Hoc network configuration route as the Control Network of Ad-Hoc network.Specifically can realize in the following way:
In the GSM/GPRS network, it (is mobile terminal number that each portable terminal with Ad-Hoc port all has its fixing control net numbering Control ID, be called for short CID), these portable terminals with Ad-Hoc port in the Ad-Hoc network mesh regularly to around broadcast its CID (promptly broadcasting the CID of this portable terminal) by the Ad-Hoc port, and regularly the center base station in the GSM/GPRS network reports (promptly sending by the GSM/GPRS port) its CID that receives, and the distance of this portable terminal and the pairing portable terminal of these CID is or/and time-delay.Wherein, distance between the portable terminal of this signal be judged and be sent to portable terminal can according to the intensity of the broadcast singal that receives, and the cycle of the time when receiving broadcast singal and each portable terminal broadcasting CID of system's agreement is judged the time-delay between the portable terminal.Like this, center base station just can obtain the situation of each portable terminal in the Ad-Hoc network, thereby can safeguard the neighbouring relations information between each node in the Ad-Hoc network, the table Power Consumption Table that comprises the energy loss that generates according to distance between the Ad-Hoc network mobile terminal (abbreviates PCT as, can adopt the sparse matrix form), or/and the time-delay table Time DelayTable (abbreviating TDT as) that generates according to the time-delay between the Ad-Hoc network mobile terminal.
Center base station can be by the PCT table or/and the TDT table be Ad-Hoc network calculations route and configuration of IP.Fig. 3 has provided the schematic flow sheet of center base station control Ad-Hoc network.
Referring to Fig. 3, the schematic flow sheet for GSM/GPRS network control Ad-Hoc network in the embodiment of the invention comprises step:
Step 301, center base station mobile terminal receive are (for convenience of description, below this portable terminal is called Sender) set up Ad-Hoc network connection requests, setting up the Ad-Hoc network with request and another portable terminal (for convenience of description, below this portable terminal being called Receiver) connects.For example, the service needed wider bandwidth of between Sender and Receiver, carrying out, and the GSM/GPRS network bandwidth be can't satisfy the time, the Ad-Hoc network that Sender can ask to be established to Receiver connects to come service data transmission.
Step 302, center base station are shown or/and the PCT table carries out route calculating according to the TDT of its maintenance, as adopt dijkstra's algorithm, find a best route (the shortest or/and QoS is best) as the path, be the node distribution dynamic IP addressing (as 10.*.*.*) on this path then, and generate route forwarding table for the portable terminal as via node on this route according to route that calculates and IP address allocated.
In this step, center base station can find a best route by route calculating according to TDT table and PCT table, for example, as shown in Figure 4, according to distance and the time-delay between each portable terminal that TDT shows and the PCT table is reflected, Sender comprises to existing 3 to satisfy professional required route between the Receiver:
Path 1:Sender-Relay1-Relay2-Receiver;
Path 2:Sender-Relay3-Relay1-Relay2-Receiver;
Path 3:Sender-Relay3-Relay4-Relay5-Receiver;
Further distance and the time-delay between each portable terminal that is reflected according to TDT table and PCT table, path 2 be the shortest apart from shortest path and time-delay, thereby selection path 2 is an optimal path.
Step 303, center base station be by sending means of signaling, and IP address allocated is configured to each node on this route, and route forwarding table is configured to via node (as the Relay3 among Fig. 4, Relay1, Relay2) on this route.
Step 304, the via node that receives route forwarding table are set up an Ad-Hoc network from Sender to Receiver according to its route forwarding table that receives and are connected, like this, Sender can send business datum by its Ad-Hoc port, this business datum will connect the Ad-Hoc port that is transferred to Receiver by this network, the business datum that Receiver sends can connect by this network equally be transferred to Sender, thereby realizes the communication that is connected based on the Ad-Hoc network between Sender and the Receiver.
In the above-mentioned flow process, preferable, center base station can be obtained the agreement of Receiver earlier before carrying out route calculating and IP address assignment.
In the above-mentioned flow process, preferable, center base station is before carrying out route calculating and IP address assignment, can confirm earlier Sender around node whether can proper communication, as, center base station can send the affirmation request message by node around the Sender node, if can receive the confirmation response message, show that then this node can proper communication, and then the alternative node that this node can be calculated as route, if do not receive or do not receive at the appointed time the affirmation response message of this node, think that then this node can not proper communication, and then this node is not considered when route is calculated.Wherein, node is determined according to TDT table and PCT table around the Sender, can be the CID that can receive Sender broadcasting (promptly with Sender exist 1 jump is connected) and time-delay be no more than the node of setting threshold, also can be to have 1 with Sender to jump or have a node that 2 jumpings are connected.
Because the mobility of node, the performance of network and topology can change along with the change of time, TDT table that might the current maintenance of center base station and PCT show can not reflect mobile terminal request Ad-Hoc network to be connected the network condition of current time, therefore, by above-mentioned affirmation mechanism, the route that center base station is calculated is the route that calculates according to current network performance and topology, thereby guarantees the success rate that route is set up.
In the middle of using in reality, because the mobility of node, the performance of network and topology can change along with the change of time, in the present embodiment, preferable, center base station can connect the Ad-Hoc network of setting up safeguards that maintenance mode comprises one of following mode or combination:
Mode one: the PCT table of center base station inspection oneself regularly, and operation dijkstra's algorithm, if the new route of the route that discovery is better than having set up, then be that the related new node of new route distributes dynamic IP addressing, allow new route and old route move a period of time simultaneously then, again old route is reclaimed, and the IP address of the via node that does not have route forwarding function is reclaimed.
Mode two: when the QoS of Sender or Receiver discovery oneself is lower than setting threshold, will ask center base station operation dijkstra's algorithm, and pick up a route that satisfies its QoS; Center base station is that the related new node of new route distributes dynamic IP addressing, allows new route and old route move a period of time simultaneously then, older route is reclaimed, and can further reclaim the IP address of the via node that does not have route forwarding function.
Preferable, after the transfer of data of Sender and Receiver finishes, can send request to center base station, connect to remove the Ad-Hoc network.Center base station can be sent signaling to the via node between Sender and the Receiver, to remove the route forwarding table of these intranodals.If the route forwarding table of certain via node is empty, its IP address (if this via node does not have response for a long time, the IP address also can be reclaimed in the base station) also can be reclaimed in the base station.
When having existed the Ad-Hoc network to connect in the actual environment, the adding of a new Ad-Hoc network connection just might be connected with existing Ad-Hoc network and intersect.In the embodiment of the invention, the node that connects for already present Ad-Hoc network need not the IP address of reallocating new, only new route forwarding table need be added in the already present Ad-Hoc network connection to getting final product in the middle of original node.
The above embodiment of the present invention not only can be applicable to text, audio frequency and ordinary video business, also can be applicable to scenes such as video conference, file-sharing.At application such as video conference, file-sharings, need set up multicast Ad-Hoc network and connect.At this moment, center base station can be moved minimal spanning tree algorithm for newly-generated figure then earlier to adopting dijkstra's algorithm in twos between the node, forms the tree of a simplification.Similar with aforementioned flow process then, center base station is that node corresponding is distributed route forwarding table, connects thereby set up multicast Ad-Hoc network.
Need to prove, be that example is described with the center base station in the GSM/GPRS network only in the foregoing description, in fact equally also can be implemented as the function of Ad-Hoc network configuration route by other network equipments in the GSM/GPRS network.In addition, the foregoing description is an example with GSM/GPRS network and Ad-Hoc network only, in fact the present invention is for not restriction of network type, for example: be used to realize that centralized route is calculated and the network of configuration also can be CDMA (Code Division Multiple Access, code division multiple access an inserts) network etc.
