Description
Technical Field
The present invention relates to a trunking communication technology, and in particular, to a method, an apparatus, and a system for selecting a data transmission format supported by a trunking group.
Background
When a terminal transmits data between an air interface and a network side, a transmitting end needs to encode the data to be transmitted, then the data is transmitted to an opposite end through a transmission layer, and the data is received by the opposite end and then decoded to obtain the data. The transmission Data may be encoded in an Adaptive Multi-rate (AMR) coding format, and the transport layer may employ a Packet Data Convergence Protocol (PDCP) layer or a real-time transport Protocol (RTP) Protocol layer. The PDCP layer belongs to a second layer of a radio interface protocol stack, and transmits and processes a radio resource management (RRC) message on a control plane and an inter-packet protocol (IP) packet on a user plane in a radio network. On the user plane, after the PDCP layer obtains the IP data packet from the upper layer, it performs header compression and encryption on the IP data packet, and transmits the IP data packet. The RTP layer generally performs transmission processing on Voice over Internet Protocol (VoIP) data encoded by AMR.
When the terminal transmits data, especially voice data messages, between the air interface and the base station, AMR coding and then VOIP transmission may be adopted, or AMR coding and then PDCP transmission may be adopted, which is called AMR over VOIP or AMR over PDCP. Further, when the base station transmits the voice data message at the air interface, because the data transmission format of the AMR over VOIP is adopted to be much larger than the data transmission format of the AMR over PDCP, the data packet obtained is much larger, so that the data transmission in the broadband trunking communication (BTrunC) network not only adopts the transmission format of the AMR over VOIP, but also is compatible with the transmission format of the AMR over PDCP.
However, after the cluster group is established, the data transmission format that can be selected is AMR over PDCP or AMR over VOIP, how to decide which data generation format is specifically selected is not defined in the BTrunC protocol, and how to select the data transmission format for establishing the cluster group becomes a problem to be solved urgently. Furthermore, when the cluster group is already established and the AMR over PDCP is used as the data transmission format, and when a base station or a terminal that does not support the AMR over PDCP data transmission format is accessed to the cluster group, the cluster group needs to switch the data transmission format to the AMR over VOIP, and how to specifically switch the data transmission format is not defined.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and examples.
A method for selecting a data transmission format when establishing a cluster group is not defined in the BTrunC protocol, which mainly means that the process of establishing a cluster group is complex, and especially under the condition that a cluster group resource is established by an accurate base station or cell, a core network side needs to calculate a list of cells and base stations where terminals in the cluster group are located according to a signed terminal in the cluster group, and the list is used when establishing the cluster group. However, different data transmission formats used by different terminals in a cluster group are different, and the data transmission format used by the base station may also be different, so that in the cluster group, both the base station and the terminal have the data transmission formats supported by them, and when determining the data transmission format supported by the cluster group, a large amount of calculation is required, which is cumbersome.
Furthermore, when the established cluster group already adopts the data transmission format of the AMR over PDCP, but due to the mobility of the terminal or the switching on and off of the terminal in the cluster group, the network side of the core network is triggered to re-establish a new base station to the cluster group resource, and the new base station does not support the AMR over PDCP data transmission format, and the data transmission format of the cluster group needs to be switched, but at this time, because the cluster group already adopts the data transmission format of the AMR over PDCP, the dynamic switching cannot be performed.
In order to solve the above problem, in the embodiment of the present invention, a data transmission format supported by each base station is stored in advance, and the data transmission format supported by the base station is determined according to a data transmission format supported by a terminal administered by the base station in a cluster group in which the base station is located. When the cluster group is established, the data transmission format supported by the cluster group is selected according to the data transmission format supported by the base station in the storage cluster group, and the data transmission is carried out by adopting the data transmission format supported by the selected cluster group.
Furthermore, when there is a cluster group established by the terminal or the base station, whether to switch the data transmission format adopted by the cluster group is determined according to the stored data transmission format supported by the base station or the base station administered by the terminal to be accessed and the data transmission format adopted by the cluster group.
Thus, embodiments of the present invention may select a supported data transmission format for a cluster group.
Fig. 1 is a flowchart of a method for selecting a data transmission format supported by a cluster group according to an embodiment of the present invention, which includes the following specific steps:
in this step, the data transmission formats supported by each base station are stored in a Distributed Database (DDB) table of the core network;
in the step, the supported data transmission format is a data transmission format adopting AMR over PDCP or a data transmission format adopting AMR over VOIP;
in the step, when the stored data transmission formats supported by all base stations in the set group all adopt AMR over PDCP, the data transmission format supported by the set group is selected to adopt AMR over PDCP;
in the step, when the stored data transmission formats supported by all base stations in the cluster group all adopt AMR over VOIP, the data transmission format supported by the cluster group is selected to adopt AMR over VOIP;
in this step, when the stored data transmission formats partially supported by all base stations in the cluster group are AMR over PDCP, the data transmission formats partially supported by the base stations are AMR over VOIP, and the data transmission format supported by the cluster group is selected as AMR over VOIP.
103, the core network side notifies the terminal in the cluster group of the data transmission format supported by the cluster group through an air interface;
in this step, the core network side notifies the terminals in the cluster group through the air interface via the base station.
In the method, a core network side stores a data transmission format supported by each base station and is sent by each base station, and the specific process is as follows:
a base station sends a request message to a core network side, wherein the request message carries a supported data transmission format identifier; the specific message is an S1Setup Request (S1 Setup Request) message, and the message carries the supported data transmission format identifier;
after receiving the message, the network side of the core network stores the data transmission format corresponding to the base station identifier supported by the base station carried by the message.
In the method, the process that the core network side determines all base stations in a cluster group and obtains the stored data transmission formats supported by all the base stations is as follows:
when a cluster is established, a core network side calculates to obtain a base station set (eBList) where a signed terminal in the cluster is located, and an AMRFlag mark of the eBList identifies a supported data transmission format, wherein when the AMRFlag mark is 0, the eBList completely supports AMR over VOIP, 1 shows that the eBList completely supports AMR over PDCP, 2 shows that the middle branch of the eBList supports AMR over VOIP, and part branch of the eBList supports AMR over PDCP.
In the method, a core network side informs a terminal of the cluster group of a data transmission format supported by the cluster group through an air interface, and the data transmission format is transmitted through a GroupCallCfg message of the air interface.
The method further comprises a process of triggering handover by terminal mobility in the cluster group:
when a mobile terminal is accessed or a base station to which the mobile terminal belongs is accessed to an established cluster group, whether to switch the data transmission format adopted by the cluster group is determined according to the stored data transmission format supported by the base station governed by the terminal to be accessed and the data transmission format adopted by the cluster group.
Specifically, if the AMRFlag flag of the eNBlist of the cluster group is AMR over PDCP, which is denoted as 1, the stored AMRFlag flag of the eNBlist of the base station governed by the terminal to be accessed is AMR over VOIP, which is denoted as 0, it is determined to switch the data transmission format used by the cluster group, and the AMR over PDCP used by the cluster group is switched to AMR over VOIP.
If the AMRFlag flag of the eNBLASt of the cluster group is AMR over VOIP, namely represented as 0, the stored AMRFlag flag of the eNBLASt of the base station administered by the terminal to be accessed is AMR over PDCP, namely represented as 1, and then the data transmission format adopted by the cluster group is determined not to be switched.
The invention is illustrated below by way of two specific examples.
Fig. 2 is a flowchart of an example of a data transmission format supported by a selected cluster group according to an embodiment of the present invention, which includes the following specific steps:
step 201, a base station sends an S1Setup Request message to a core network side, carries an AMR over PDCP or AMR over VOIP indication, and the core network side stores the received message in a DDB table;
storing a data transmission format supported by each base station, namely an AMR over PDCP identifier or an AMR over VOIP identifier adopted by the base station in a DDB table;
step 202, a core network side establishes a cluster group, calculates to obtain a base station set eNBLIst according to a signed terminal of the cluster group, and selects a data transmission format supported by the cluster group according to an AMRFlag identifier of the eNBLIst in a DDB table;
in this step, assuming that AMRFlag of eNBList of the cluster group is 1, selecting the data transport format supported by the cluster group as AMR over PDCP;
step 203, the network side of the core network sends the data transmission format AMR over PDCP adopted by the cluster group to the terminal in the cluster group through the air interface.
Step 204, because of the mobility of the terminal in the cluster group, the base station of the cluster group is accessed to the cluster group, and the core network side judges that the AMRFlag identifier of the new eNBLIst of the newly accessed base station is AMR over VOIP, then switching is carried out, namely, the data transmission format adopted by the original eNBLIst is released, and the AMR over VOIP is adopted as the data transmission format of the cluster group;
step 205, the network side of the core network sends the data transmission format AMR over VOIP adopted by the cluster group to the terminals in the cluster group through an air interface.
Fig. 3 is a flowchart of an example of a data transmission format supported by a selected set group according to an embodiment of the present invention, which includes the following specific steps:
step 301, the base station sends an SI Setup Request message to the core network side, carries an AMR over PDCP indication, and the core network side stores the received message in a DDB table;
storing a data transmission format supported by each base station in a DDB table, namely an AMR over PDCP identifier or an AMR over VOIP identifier adopted by the base station;
step 302, a core network side establishes a cluster group, calculates to obtain a base station set eNBLIst according to a signed terminal of the cluster group, and selects a data transmission format supported by the cluster group according to an AMRFlag identifier of the eNBLIst in a DDB table;
in this step, assuming that AMRFlag of eNBList of the cluster group is identified as 0, selecting the data transmission format supported by the cluster group as AMR over VOIP;
step 303, the network side of the core network sends the data transmission format AMR over VOIP adopted by the cluster group to the terminals in the cluster group through an air interface.
Step 304, because of the mobility of the terminal in the cluster group, the base station belonging to the cluster group is accessed to the cluster group, the core network side judges that the AMRFlag identifier of the new eNBLIst of the newly accessed base station is AMR over PDCP, the switching is not carried out, and AMR over VOIP is still adopted as the data transmission format of the cluster group.
