Embodiment
The communication network coexist of multiple network standard, as the communication network coexist of the network formats such as 2G, 2.5G, 3G, 3.9G, is one of principal character of present communications network distribution.The communication network of various different network formats is all deployed with respective access device.For improving signal cover and improving signal strength signal intensity, the deployment of access device presents that density is large, distribute the feature such as wide, and this makes the addressing of newly-increased access device be very restricted.In order to improve the utilance of access device site resource, save site construction cost, colocation site technology is day by day universal, and wherein, colocation site technology is that at least two access devices are arranged on identical site, as arranged two access devices in same machine room.
Can not direct interaction between traditional access device belonging to the different communication network of isomery, the transfer of data between access device, as data cached transmission relevant to this terminal in terminal switch implementation, need carry out transfer by core net and complete.
Inventor finds after carefully studying, when the access device of the different communication network belonging to isomery is respectively arranged at same site and colocation site, physical distance between the access device of colocation site is nearer, therefore, in the scene of the access device colocation site of heterogeneous network, the feature that access device physical distance is nearer can be made full use of, conventional transmission mode data cached in terminal switch implementation is improved, to reduce the handover delay introduced because of core net forwarding cache data.Concrete, the main thought of technical solution of the present invention comprises: between the access device belonging to the different communication network of isomery and colocation site, set up the interface that direct transfers, by this interface transmission terminal that direct transfers switch between this heterogeneous network data cached, make described data cached without the need to forwarding through core net thus, therefore alleviate the load of core net forwarding data, decrease the handover delay that data cached transmission is introduced.
Below in conjunction with the drawings and specific embodiments, technical scheme of the present invention is described in detail.
The flow chart of data transmission method for uplink between the heterogeneous network that Fig. 1 provides for the embodiment of the present invention one.The present embodiment is the access device from the current access of to be switched terminal, and namely the angle of the source access device of source network is described.Method as shown in Figure 1 comprises:
11: obtain relevant to be switched terminal data cached; Describedly data cachedly be: in source network, source access device has sent to described terminal but not yet received the data of described terminal check response.
Source access device, after determining that terminal needs to carry out to switch between heterogeneous network, can carry out the configuration of the communication resource needed for terminal switch by notification target network.After objective network completes the configuration of the communication resource needed for terminal switch, can notification source access device.Source access device, after receiving corresponding notice, can determine that objective network completes the configuration of the communication resource needed for terminal switch.
Data relevant to terminal on the access device of source can comprise: confirm data and data cached; Wherein, confirm that data are that source access device has sent to terminal and received the data of terminal check response, data cached is that source access device has sent to terminal but has not yet been subject to the data of terminal check response.For ensureing that terminal is to the correct reception of the data that source access device sends, after terminal switch to the Target cell that target access device covers, data cached likely needs retransmits, to ensure the continuity of terminal current request business.Therefore, source access device needs, by relevant to this terminal data cached, to send to target access device.
12: when described source network and objective network isomery, according to the site information of target access device in described objective network, determine described target access device whether with described source access device colocation site.
Source access device is previously stored with the site information of target access device.If the source network of terminal and objective network isomery, the site information of the site information of target access device and source access device self compares by source access device.If target access device is identical with the site information of source access device, represent target access device and source access device colocation site; Otherwise, represent target access device and source access device not colocation site.
13: if interface sends described data cached to described target access device by direct transferring; Otherwise, through the core net of described source network and the core net of described objective network, forward described data cached to described target access device; The described interface that direct transfers is: the physical communication interface set up in advance between described source access device and described target access device.
Source access device send to target access device described data cached after, can send to terminal and switch instruction, this switching instruction is used to indicate the cell-of-origin that terminal covers from source access device, is switched to the Target cell of target access device covering.
Data transmission method for uplink between the heterogeneous network that the present embodiment provides, carry out in the process switched between heterogeneous network in terminal, the physical communication interface set up in advance between access device by the different communication network and colocation site that belong to isomery, namely direct transfer interface, sends relevant to terminal data cached directly to target access device.Data cachedly to forward without the need to core net due to described, therefore alleviate the load of core net forwarding data, and decrease the handover delay introduced because of described data cached transmission, and then be conducive to the continuity ensureing business before and after terminal switch.
In technique scheme, source access device, when determining target access device and its colocation site, sends described data cached by the described interface that direct transfers to described target access device.Due to source network and objective network isomery, therefore source access device is different with the communication standard of target access device, and namely source access device communicates according to different communication protocol with target access device.
In a kind of optional implementation, can by source access device to data cached carry out user plane protocol conversion process after, by direct transferring, interface sends data cached.Such as: source access device to described data cached protocol conversion process of carrying out from first user face communication protocol to the second user face communication protocol, and the interface that direct transfers described in passing through to send after protocol conversion process to described target access device described data cached; Wherein, described first user face communication protocol is the user face communication protocol that described source access device is supported, described second user face communication protocol is the user face communication protocol that described target access device is supported.Under this situation, target access device by the interface that direct transfers arrive described data cached, without the need to carrying out the protocol conversion process in user face again.
In another kind of optional implementation, source access device, when sending data cached, does not carry out user plane protocol conversion process, target access device receive described data cached time, then carry out the protocol conversion process in user face.Such as: target access device by the source access device described in interface of direct transferring send described data cached after, to described data cached protocol conversion process of carrying out from described first user face communication protocol to described second user face communication protocol, and preserve described data cached after protocol conversion process.
