Embodiment 1

[0030] Embodiment 1 provides a service data transmission method, such as Figure 2A shown. This example is particularly suitable for Figure 2B~2E In the network architecture shown. Such as Figure 2B and 2C As shown in , the access network includes a management control center, cluster head base stations at all levels, and sub-base stations. The cluster head base station that directly communicates with the management and control center is the first level cluster head base station, and the cluster head base station that directly communicates with the first level cluster head base station is the second level cluster head base station, and so on until the Nth level cluster head base station. Each base station has only one cluster head base station to which the base station belongs. Preferably, N is 3. Each cluster head base station is not only connected to the next cluster head base station directly communicating with it, but also connected to the next level sub base stati...

Embodiment 2

[0069] This embodiment further limits the method for transmitting service data in the foregoing embodiments.

[0070] Embodiment 2 further limits the steps for the cluster head base station in embodiment 1 to obtain the second transmission path from the routing table maintained by the cluster head base station, and other steps are the same as in embodiment 1.

[0071] Specifically, when it is recognized that the target base station directly belongs to the cluster head base station, the cluster head base station acquires the second transmission path in the maintenance routing table of the cluster head base station including:

[0072] The cluster head base station searches the routing table to obtain the preset path between the base station reporting the service request and the target base station;

[0073] The cluster head base station selects the path containing the least number of transit base stations from the preset paths, and sets this path as the second transmission path ...

Embodiment 3

[0077] This embodiment further defines the service data transmission method in Embodiment 1.

[0078] This embodiment only further limits the steps of the cluster-head base station determining the temporary transmission path between the base station that reports the service request and the next-level cluster-head base station that receives the service request, and other steps are consistent with those in the first embodiment.

[0079] Specifically, the cluster-head base station determines the temporary transmission path between the base station that reports the service request and the next-level cluster-head base station that receives the service request, including:

[0080] The cluster head base station searches the routing table maintained by itself to obtain the preset path between the base station reporting the service request and the next level cluster head base station receiving the service request;

[0081] The cluster head base station selects the path containing the l...

Abstract

The invention discloses a business data transmission method and device. The business data transmission method comprises the following steps: a cluster head base station receives a business request which is reported by a source terminal or a next level of base station, which is directly affiliated to the cluster head base station; the cluster head base station identifies whether a target base station is affiliated to the cluster head base station according to a target terminal identifier, and judges whether the cluster head base station acquires a second transmission channel according to an identification result; the cluster head base station generates connection signaling according to the acquired transmission channel and stepwise issues the connection signaling and a business data identifier to the next level of cluster head base station and the next level of sub base station, which is contained in the transmission channel; the cluster head base station or the sub base station which receives the connection signaling establishes a data straight-through channel with the adjacent cluster head base station and / or adjacent sub base station in the transmission channel according to the connection signaling, and transmits business data in the data straight-through channel according to the business data identifier. According to the business data transmission method and device disclosed by the invention, the business data can be directly transmitted among the base stations.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a service data transmission method and device. Background technique [0002] In 3G devices, base station networking adopts a hierarchical deployment mode. Multiple NodeBs (Node Bs) can be connected to a unified RNC (Radio Network Controller, wireless controller), and connected to the core network through the RNC. [0003] Such as figure 1 As shown, when the source NodeB 101 covering the source terminal needs to send service data to the target NodeB 104 covering the target terminal, the service data is first sent to the source RNC 102 through the source NodeB 101, and the source RNC 102 transmits the service data to the core network 103. The network 103 is converged and then sent to the target RNC105 to which the target NodeB104 belongs, and then the service data is sent to the target NodeB104 through the target RNC105 to which the target NodeB104 belongs, a...
