Description

A transmission method for citing neighbor cell BS information

technical field

The invention relates to the technical field of network communication, in particular to a transmission method for citing adjacent cell BS information.

Background technique

802.16e is a mobile wireless broadband access standard being developed by the IEEE (Institute of Electrical and Electronics Engineers) standard organization. In this standard, the wireless mobile communication system is mainly composed of two parts, the base station BS and the mobile terminal MSS. Each BS can communicate with multiple MSSs within its coverage area. Although the coverage of each BS is limited, multiple BSs can be connected together according to certain rules to form a wireless communication network with a large coverage. The MSS within the coverage of the wireless communication network can maintain normal communication with the BS. . Usually, an MSS only maintains communication with one BS, and this BS is called the serving BS of the MSS.

Since each BS has limited coverage, and MSS is generally a mobile entity, at some point, as the MSS moves, the MSS will be farther and farther away from the BS it currently serves, making the distance between the two The communication quality becomes worse and worse, so that the communication quality requirements cannot be met. In this case, the MSS needs to leave the old serving BS, switch to a new BS that can meet the communication quality requirements, and continue to communicate. This process is called switching.

As the MSS moves, the MSS may need to pass through the coverage areas of multiple BSs and perform a series of handover procedures. In order to ensure the continuity of communication and reduce the communication interruption caused by handover, when MSS maintains a normal communication state with BS, it also needs to frequently detect the signal quality of neighboring BSs to seek potential handover target BSs. This process is called scanning.

In practical applications, the BS and MSS trigger corresponding scanning and handover actions through signaling interaction. Generally speaking, the signaling between the BS and the MSS will include some information about BSs in neighboring cells as recommended scanning targets and handover targets, so as to speed up the process of scanning and handover.

In the current draft of the 802.16e protocol, there are two main ways for the MSS to obtain the BS topology information of the neighboring cell: one is the broadcast message MOB NBR-ADV of the BS topology structure of the neighboring cell periodically sent by the MSS through its serving BS The ordered list of BSs in neighboring cells is included, and the second is from the previous interaction records saved by the MSS.

In related signaling triggered by scanning and handover, such as MOB_SCN-REQ, MOB_SCN-RSP, MOB_SCN-REP, MOB_ASC-REP and MOB_MSHO-REQ, a flag called Comp_NBR_BSID_IND is used to indicate the neighbor cell BS contained in the signaling Whether it comes from the broadcast message MOB_NBR-ADV or from previous interaction records, such as the structure of the MOB_SCN-REQ management message is shown in Table 1.

In Table 1, Comp_NBR_BSID_IND occupies one bit. When Comp_NBR_BSID_IND is 1, it means that the BS information of the neighboring cell carried in the MOB_SCN-REQ comes from a broadcast message; otherwise, it means that the BS information of the neighboring cell carried in the MOB_SCN-REQ comes from the previous interaction record.

From the message structure in Table 1, it can be seen that the BS information of the neighboring cell carried in the signaling management message either refers to the neighboring cell BS in the MOB_NBR-ADV broadcast message, or refers to the neighboring cell BS in the non-MOB_NBR-ADV broadcast message, such as referring to the previous When the neighbor cell BS in the interaction record needs to refer to neighbor cell BSs from different sources, multiple signaling management messages need to be sent, and the method of neighbor cell BS reference is inflexible, thus wasting precious air interface resources.

Detailed ways

The core of the present invention is: set the fields corresponding to the BS information of neighboring cells with different reference sources in the predetermined message, and the sending end will carry the BS information of neighboring cells with different reference sources in a predetermined message according to the set fields and send it to the receiving end . Here, the BS information of neighboring cells with different reference sources carried in the predetermined message may be all the neighboring cell BS information that the sending end needs to send to the receiving end, or it may be part of the neighboring cell BS information that the sending end needs to send to the receiving end, that is, That is to say, all the neighboring cell BS information that the sending end needs to send to the receiving end can be sent to the receiving end through one predetermined message, or can be sent to the receiving end through multiple predetermined messages. Regardless of whether the sending end sends the BS information of neighboring cells from different sources to the receiving end through a predetermined message, or sends the BS information of neighboring cells from different sources to the receiving end through multiple predetermined messages, one predetermined message will carry the BS information of different sources. Cell BS information.

The technical solution provided by the present invention will be further described below based on the core idea of the present invention.

The transmission method of citing neighboring cell BS information of the present invention is shown in FIG. 1 .

In Figure 1, the predetermined message transmitted between the sender and the receiver contains the BS information of neighboring cells with different reference sources. In this way, the sender can transmit the BS information of neighboring cells with different reference sources to the receiver by sending a message. end, which avoids the phenomenon in the prior art that multiple message transmissions are required to complete the transmission of neighboring cell BS information from different reference sources, thereby reducing message overhead and improving the efficiency of air interface resource usage.

In the present invention, the transmission of the predetermined message referencing the BS information of the adjacent cell includes: the signaling management message triggering scanning and the signaling management message triggering switching in 802.16e, specifically as MOB_SCN-REQ (scanning request) message, MOB_SCN-RSP (scanning request Response) message, MOB_SCN-REP (scanning result report) message, MOB_ASC-REP (association report) message and MOB_MSHO-REQ (terminal handover request) message, etc.

The present invention firstly needs to define the field structure related to quoting neighboring cell BS information in the above message, and the field structure corresponds to the specific content of quoting neighboring cell BS information from different sources that needs to be transmitted.

The different reference sources of the neighboring cell BS in the present invention can be: MOB_NBR-ADV (Network Topology Broadcast) message and past interaction records saved by MSS.

There are various specific representation modes for citing neighboring cell BS information from different sources in the message, and two specific representation modes are mainly introduced in this embodiment.

Way 1: The number of neighboring cell BSs and the neighboring cell BS identification information corresponding to different reference sources are used to indicate in the message that the neighboring cell BS information from different sources is cited.

For the reference source of the network topology broadcast message MOB_NBR-ADV, the neighboring cell BS identification information may include: the count value of the network topology broadcast message MOB_NBR-ADV, the neighbor cell BS listed in a circular enumeration in the network topology broadcast message MOB_NBR-ADV Index value in .

The count value of the network topology broadcast message MOB_NBR-ADV is generally: the count value of the latest network topology broadcast message MOB_NBR-ADV.

Since the message is set with the number of neighboring cell BSs referencing the network topology broadcast message MOB_NBR-ADV, when the message is transmitted to the receiving end and the number of the neighboring cell BS in the message is not zero, the receiving end can use The index value of each neighboring cell BS in the network topology broadcast message MOB_NBR-ADV is acquired from the message in a cyclic reading manner.

The receiving end may determine each neighboring cell BS from the corresponding network topology broadcast message MOB_NBR-ADV according to the count value of the network topology broadcast message MOB_NBR-ADV and the obtained index value.

For the reference source of the past interaction record saved by the MSS, the BS identification information of the neighboring cell may be: the BS identifier of the neighboring cell listed in a circular enumeration manner.

Since the message is set with the number of neighboring cell BSs that refer to the past interaction records saved by the MSS, when the message is transmitted to the receiving end and the number of the neighboring cell BS in the message is not zero, the receiving end can use the The BS identifier of each neighboring cell is obtained from the message in a cyclic reading manner.

The receiving end can directly determine the BSs of the neighboring cells according to the BS identifiers of the neighboring cells.

In mode 1, when the number of neighbor cell BSs referencing the network topology broadcast message MOB_NBR-ADV and the number of neighbor cell BSs referencing past interaction records saved by the MSS are both non-zero, the message sent by the sender It bears the BS information of neighboring cells from different sources, so that the BS information of neighboring cells from different sources can be flexibly reflected in one message at the same time, so that the purpose of transmitting BS information of neighboring cells from different sources can be achieved by sending one message, avoiding The phenomenon in the prior art that multiple message transmissions are required to complete the transmission of neighboring cell BS information from different sources, thereby reducing message overhead and improving air interface resource usage efficiency.

In mode 1, if the number of neighbor cell BSs referencing the network topology broadcast message MOB_NBR-ADV or the number of neighbor cell BSs referencing past interaction records saved by the MSS is zero, the message sent by the sender only carries There is a reference source for neighbor cell BS information.

Method 2: Use the total number of neighboring cell BSs from different reference sources, the identification information of each neighboring cell BS identification information from different reference sources, and the source identification information corresponding to each adjacent cell BS identification information that occupies at least 1 bit to indicate in the message that different sources are cited BS information of neighboring cells.

For the reference source of the network topology broadcast message MOB_NBR-ADV, the BS identification information of the neighboring cell may include: the count value of the network topology broadcast message MOB_NBR-ADV, the BS of the neighboring cell listed in the same circular enumeration manner as the BS identifier of the neighboring cell. The index value in the network topology broadcast message MOB_NBR-ADV.

For reference sources of previous interaction records saved by MSS, the BS identification information of neighboring cells may include: BS identifiers of neighboring cells listed in the same circular enumeration as the index value of BS in the network topology broadcast message MOB_NBR-ADV .

Since the message is set with the total number of neighbor cell BSs referencing the network topology broadcast message MOB_NBR-ADV and previous interaction records saved by the MSS, the receiving end can use the cyclic reading method according to the total number, and use the BSs of each neighbor cell The source identification information is the basis for judging by obtaining the index value of the neighboring cell BS in the broadcast message MOB_NBR-ADV and the identifier of the neighboring cell BS from the message.

The receiving end can determine each neighboring cell BS from the corresponding network topology broadcast message MOB_NBR-ADV according to the count value of the network topology broadcast message MOB_NBR-ADV and the above-mentioned index value. Neighboring cell BS.

In the expression mode of mode 2, if the source identification information is set to occupy 1 bit, and the source identification information is 1, it means that the adjacent cell BS identification information corresponding to the source identification information is the adjacent cell BS in the broadcast message MOB_NBR-ADV When the source identification information is 0, it means that the adjacent cell BS identification information corresponding to the source identification information is the adjacent cell BS identifier, then when the source identification information includes both 0 and 1, the message sent by the sender carries The BS information of neighboring cells from different sources can be quoted, so that the BS information of neighboring cells from different reference sources can be flexibly reflected in one message at the same time, so that the purpose of transmitting BS information of neighboring cells from different reference sources can be achieved by sending one message, avoiding In the prior art, it is necessary to transmit multiple messages to complete the transmission of neighboring cell BS information from different reference sources, thereby reducing message overhead and improving air interface resource usage efficiency.

In the expression mode of mode 2, if the source identification information only includes 0 or only 1, the message sent by the sender only carries the BS information of a reference source of the neighboring cell.

Taking the structure of the MOB_SCN-REQ management message as an example in combination with Table 2 and Table 3, the method of setting the BS information of neighboring cells from different sources in the message of the present invention will be described.

When N_Recommended_BS_Index is zero, it means that there is no index value of the neighbor cell BS that references the network topology broadcast message MOB_NBR-ADV in the message; N_Recommended_BS_Index is When it is non-zero, it means that the message carries the index value of the neighbor cell BS referencing the network topology broadcast message MOB_NBR-ADV.

When N_Recommended_BS_Index is non-zero, the present invention should give the latest count value Configuration change count for MOB_NBR_ADV of the network topology broadcast message MOB_NBR_ADV, and then list the index value of the adjacent cell BS in the network topology broadcast message MOB_NBR_ADV in a circular enumeration.

Next, the present invention should provide the number N_Recommended_BS_Full of the neighbor cell BS that refers to the previous interaction records stored by the MSS. When N_Recommended_BS_Full is zero, it means that the message does not carry the neighbor cell BS identifier. When N_Recommended_BS_Full is non-zero, it means that the message contains The BS identifier of the neighboring cell carrying the past interaction records stored by the MSS.

Finally, when N_Recommended_BS_Full is non-zero, the neighbor cell BS identifier ID should be listed in a circular enumeration manner.

For example, when Comp_NBR_BSID_IND is 1, it means that the network topology broadcast message carries at least one neighbor cell BS from the network topology broadcast message. At this time, the MOB_SCN-REQ message may contain only The neighbor cell BS that carries the broadcast message from the network topology may also carry the neighbor cell BS from the network topology broadcast message and the neighbor cell BS from the past interaction records; when Comp_NBR_BSID_IND is 0, it means MOB_SCN-REQ message The BS information of neighboring cells carried in the BS comes from previous interaction records.
