Step 36, it is determined that the air interface resource on receive described in first transmission node sends The information of terminal, and be institute according to the information of the terminal in the terminal after the switching of the first transmission node State terminal and service is provided.

In centralized architecture, typically there is a local centralized node to be used for what is concentrated to transmission node TP Management and control.For terminal, the chain of command of terminal is also attached to centralized node, and transmission node is It is responsible for data dispatch and transmission.For example, its whole (the Radio Resource control of layer three of data/signaling bear of terminal Rrc layer processed) and safety-related protocol stack (such as radio resource control RRC, PDCP PDCP Deng) centralized node is respectively positioned on, and layer two (MAC layer) and following protocol stack are located at transmission node (such as wireless chain control layer agreement RLC, MAC layer MAC, physical layer PHY etc.).Work as end End needs to move to the second transmission node from the first transmission node, when enjoying continuation service, in order to avoid to end The state at end cause reset etc. influence, it is necessary to by all status informations of terminal, transmission information and caching number It is believed that breath etc., is forwarded to the second transmission node, so as to ensure that the second transmission node can from the first transmission node The service continued to terminal.The maximum purpose so migrated, is also to save the configuration signal eated dishes without rice or wine, State reset, the decline for the message transmission rate being likely to result in and the unnecessary re-transmission money of eating dishes without rice or wine for avoiding terminal The waste in source.

Specifically, under centralized architecture, the configuration information of air interface resource is generated by centralized node, tool Body, the channel information that centralized node is reported according to terminal or the first transmission node judges whether terminal needs Switch service node or increase service node；When terminal needs to switch or increases service node, collection Interior joint sends a notification message to the first transmission node and the second transmission node respectively, notifies two nodes, needs Carry out the service switching of terminal or add new service node, and inform two nodes simultaneously, be used for into The resource allocation information of the information of row air interface transmission terminal.

Further, the collection process of centralized architecture lower channel information is as follows：

Terminal carries out normal data transfer in the first transmission node, wherein transmission node be responsible for data dispatch and Tissue of packet etc., and the chain of command of terminal is concentrated mainly on centralized node.Centralized node is carried out to terminal Measurement configuration, measurement and measurement for terminal-pair adjacent node are reported；Or centralized node configurating terminal The resource location that upward cycle signal is sent is carried out, and the resource distribution is informed to the neighbouring section of terminal surrounding Point, in order to adjacent node can to terminal carry out up channel measurement, and by measurement result periodically or What person's event was triggered reports centralized node.

Preferably, the first transmission node needs to collect metrical information on terminal, and by channel measurement information Report centralized control node.The metrical information can be that terminal is reported or the first transmission node The measurement result (being reported by the first transmission node) carried out to terminal.Wherein, the measurement of terminal is reported usually Terminal-pair closes on the down channel measurement situation of transmission node, can be based in layer one (such as physical layer) process Report or layer three (such as RRC) process are reported.The measurement of layer one reports usually that the short period is (for example Several milliseconds) measurement result, and report quick, expense is smaller, reacts instantaneous channel quality；And layer Three measurements report the result after the usually measurement processing of long period (such as hundreds of milliseconds), and layer three Report the time of needs longer, expense is big, and reaction is average channel quality situation.If taking the first biography Defeated node measurement terminal, then measured, and each pass by the first transmission node to the upward signal of terminal Defeated node will meet measurement request (such as received signal level or quality meet certain threshold requirement) Measurement result reports centralized node respectively, by centralized node integrated treatment.Transmission node measurement benefit be The expense reported is saved, but needs to be used for transmission node to the upward signal that sends of terminal configuration cycle property Up channel is measured.

Further, when centralized node receives metrical information, all metrical informations are collected, And judge whether to need the replacing or increase of progress service node, if it is, needing to related transmission Node sends terminal service node change/update notification signaling；In general, when the first transmission node to terminal Channel quality no longer meet requirement, and the second transmission node to the channel quality of terminal meet transmission requirement when, Service node replacing can be carried out；And when it is terminal service to take node set, can be because of the second transmission section Point meets basic transmission requirement to the channel quality of terminal, and second transmission node is added to the service of terminal Set, subsequently participates in the service to terminal.No matter it is above-mentioned which kind of, the second transmission node be required for obtain terminal Status information, transmission information and data cached.

Centralized node sends a notification message to the first transmission node and the second transmission node respectively, notifies two sections Point, it is necessary to carry out the service switching of terminal or add new service node, and inform two nodes simultaneously, Resource distribution for carrying out air interface transmission end message.

Further, the first transmission node receives the notification message of centralized node, being used for of being configured into In the interface-free resources of row end message transmission, the status information of the terminal is transmitted to the second transmission node, is transmitted Information and data cached.If terminal related information data are not enough passed than relatively large in the resource configured It is defeated, then the mode that dispatch is sent from the first transmission node to the second transmission node can also be taken, to accuse Know follow-up transmission used resource.Further, because the first transmission node and the second transmission node belong to network In known node, therefore can from the first transmission node to the second transmission node carry out wave beam forming, to carry Rise efficiency of transmission.Second transmission node receives the notification message of centralized node, is being configured for carrying out In the interface-free resources of end message transmission, the end message for coming from the first transmission node is received；Afterwards for eventually End provides follow-up data transport service.

The third embodiment of the present invention is the transmission method of the end message based on centralized architecture, and the 3rd is real Apply in example by a centralized node to transmission node progress centralized management, and by centralized node to the first transmission section Point and the second transmission node carry out Notification of Changes, and are notifying to carry for air interface transmission terminal simultaneously The resource allocation information of information, in the air interface resource position configured, the first transmission node is by the terminal Status information, transmission information and it is data cached be sent to the second transmission node, the second transmission node subsequently may be used To continue to carry out the service of continuing to terminal, the configuration signal eated dishes without rice or wine is saved, it is to avoid the state reset of terminal, The decline for the message transmission rate being likely to result in and the waste of unnecessary retransmission resource of eating dishes without rice or wine, improve network effect Rate and Consumer's Experience.

Step 45, the terminal is sent to second transmission node in identified air interface resource Information so that the terminal is switched to after second transmission node from the first transmission node, described second passes Defeated node for terminal can provide service according to the information of the terminal.

Accordingly, the second transmission node side, as shown in fig. 7, the transmission method includes：

Step 46, the letter that the first transmission node is reported according to the terminal or second transmission node is received Road information determines that terminal needs the money needed after switching or increase service node according to the transmission end message The configuration information of the air interface resource of the information for transmission terminal of source quantity generation.

Step 47, according to the configuration information of the air interface resource, the air interface resource is determined.

Step 48, it is determined that the air interface resource on receive described in first transmission node sends The information of terminal, and be institute according to the information of the terminal in the terminal after the switching of the first transmission node State terminal and service is provided.

Centralized management is carried out to transmission node in distributed structure/architecture, and in the absence of centralized node, each transmission Node carries out self operation, and by the interaction between transmission node, carries out the coordination between node and cooperation behaviour Make.

Specifically, under distributed structure/architecture, the configuration information of air interface resource is generated by the first transmission node, Specifically, the channel information that the first transmission node is reported according to the terminal or second transmission node, Judge whether terminal needs switching service node or increase service node；When terminal needs to switch or increases During service node, the first transmission node sends a notification message to the second transmission node, notifies the second transmission node Need to carry out the service switching of terminal or add new service node, and inform the second transmission node simultaneously, For the resource allocation information for the information for carrying out air interface transmission terminal.

Further, the collection process of distributed structure/architecture lower channel information is as follows：

Terminal carries out data transmission, in order to protect under the control of its service node (i.e. the first transmission node) The promptness and smoothness of terminal movement are demonstrate,proved, service node can carry out the survey of surrounding adjacent node with configurating terminal Amount, and reported according to trigger condition and (for example periodically report, or meet trigger condition and reported)； Or service node configurating terminal carries out periodic upward signal transmission, and by the resource of terminal uplink signal The adjacent node of surrounding is informed in configuration, and terminal is measured by adjacent node, and specifying measurement interaction triggering Condition, the terminal signaling power for example received meets certain thresholding or the quality of reception meets certain thresholding, Source node can be sent to by measurement result by meeting the neighbouring transmission node of measurement interaction trigger condition, in case subsequently Terminal service node change/renewal.
