Description

Notification of Link Merging, Method and Device for Obtaining

technical field

The embodiments of the present invention relate to the communication field, and in particular to a method and device for notifying and acquiring link merging conditions. the

Background technique

After introducing the High Speed Packet Access (HSPA) technology into the Wideband Code Division Multiple Access (WCDMA) system, messages and wireless communication can be established through wireless links. A link addition message is used to establish a radio link, and a Dedicated Channel (DCH) or an Extended Dedicated Channel (EDCH) can also be added to the active set through a radio link reconfiguration prepare message. According to the latest signaling protocol of the interface (IUR interface) between the Serving Radio Network Controller (hereinafter referred to as: SRNC) and the Drift Radio Network Controller (hereinafter referred to as: DRNC), in When dealing with the merging of multiple wireless links, there may be problems affecting data transmission performance caused by the fact that the SRNC is not aware of the merging of multiple wireless links in the DRNC. the

As shown in Figure 1, it is a schematic diagram of the connection between SRNC and DRNC in the prior art. Three wireless links are connected between SRNC1 and DRNC2, which are respectively wireless link 3, wireless link 4 and wireless link 5, wherein the wireless link Route 3 belongs to NodeB6 on the side of DRNC2, and radio link 4 and radio link 5 belong to NodeB7 on the side of DRNC2. In Figure 1, EDCH FP on the side of SRNC1 and NodeB6 and NodeB7 represent radio link 3, radio link 4 and radio link 5 adopts EDCH frame agreement. According to FIG. 1 , the problems affecting data transmission performance caused by the fact that the SRNC is not aware of the link merging in the DRNC are introduced in three cases. the

Case 1: It is assumed that the above three wireless links are established through a wireless link establishment message, specifically, three EDCHs may be requested to be established at a time in a radio link establishment request message. According to the signaling protocol of the IUR interface, wireless link 4 and wireless link 5 will be merged in NodeB7. Since wireless link 3 belongs to NodeB6, wireless link 3 will not be merged with wireless link 4 or wireless link 5. The fields shown in Table 1, Table 2 and Table 3 are included in the wireless link establishment response message returned to SRNC1, wherein Table 1 is the field in the wireless link establishment response message of wireless link 3, and Table 2 is the field in the wireless link establishment response message of wireless link 3. For the fields in the wireless link setup response message of link 4, Table 3 shows the fields in the wireless link setup response message of wireless link 5. the

Table 1. Fields in the wireless link establishment response message of wireless link 3

＞Diversity instruction selection ＞＞Do not merge or first link ＞＞＞DCH response information ＞＞＞E-DCH FDD response information

Because wireless link 3 is not combined with other wireless links, the DCH response information and EDCH frequency division duplex (EDCH FDD) response information will be carried in the non-combination field of the "diversity indication selection" field. the

Table 2. Fields in the wireless link establishment response message of wireless link 4

＞Diversity instruction selection ＞＞Merge ＞＞＞RL ID＝1 ＞＞＞DCH response information ＞＞＞E-DCH FDD response information

Because radio link 4 and radio link 5 are merged, and radio link 4 is established before radio link 5 is established, the EDCH FDD response information will be carried in the combined field of the "diversity indication selection" field, and the DCH response will not be carried. Information, that is to say, the EDCH FDD response information field in Table 2 carries corresponding EDCH FDD response information, but does not carry any information in the DCH response information field, which is an empty field. the

Table 3. Fields in the wireless link establishment response message of wireless link 5

＞Diversity instruction selection ＞＞Merge ＞＞＞RL ID＝1 ＞＞＞DCH response information ＞＞＞E-DCH FDD response information

Because wireless link 5 is combined with wireless link 4, and wireless link 5 is established after wireless link 4 is established, the combining field (Combining) of the "diversity indication selection" field will not carry DCH response information and EDCH Frequency division duplex response information, that is, the DCH response information field and the EDCH FDD response information field in Table 3 do not carry any information, and are all empty fields. the

After analysis, the inventor believes that there are defects in the solutions in the prior art, as follows:

The defect in the first case is: after SRNC1 receives the wireless link establishment response message of each wireless link, it cannot judge whether it is wireless link 3 or wireless link 4 that is merged with wireless link 5, if SRNC1 thinks that When the wireless link 5 is merged with the wireless link 3, when the wireless link 4 is deleted by executing the wireless link deletion message, the frame protocol (FP) and the corresponding transmission bearer corresponding to the wireless link 4 will be released. In fact, The wireless link 5 is carried on the FP where the wireless link 4 is located and its transmission bearer, which causes the data transmission of the wireless link 5 to be interrupted, seriously affecting the performance of data transmission. the

The second case: it is assumed that wireless link 3 is established through a wireless link establishment message, and wireless link 4 and wireless link 5 are established through a wireless link addition message, and these three wireless links are all EDCH links. Since wireless link 3 and wireless link 4 belong to different NodeBs, the response message returned to SRNC1 will carry an EDCH frequency division duplex response message, which further carries a binding identifier and a transport layer address. Since the wireless link 5 is merged with the wireless link 4, when the wireless link 5 is established through the wireless link increase message, the response message returned to SRNC1 will not carry the EDCH frequency division duplex response message, and will not carry the binding Therefore, SRNC1 cannot determine whether wireless link 3 or wireless link 4 is merged with wireless link 5. If SRNC1 thinks that wireless link 5 is merged with wireless link 3, it will execute the wireless link deletion message When wireless link 4 is deleted, the FP corresponding to wireless link 4 and the corresponding transmission bearer will be released, but in fact, wireless link 5 is carried on the FP where wireless link 4 is located and its transmission bearer, resulting in The data transmission of road 5 is interrupted, which seriously affects the performance of data transmission. the

The third case: assume that the original three DCH links in DRNC2 are reconfigured into EDCH links through the radio link reconfiguration preparation message, then the radio link reconfiguration returned to SRNC1 through radio link 3 and radio link 4 The preparation complete message will carry the EDCH frequency division duplex response message, which further carries the binding identifier and the transport layer address, but the radio link reconfiguration preparation complete message returned to SRNC1 through the wireless link 5 will not carry the EDCH frequency division duplex response message. The duplex response message does not carry the binding identifier and the transport layer address. Similarly, SRNC1 cannot determine whether the wireless link 3 or the wireless link 4 is merged with the wireless link 5, which affects the performance of data transmission. the

Detailed ways

The technical solutions of the embodiments of the present invention will be described in further detail below with reference to the drawings and embodiments. the

As shown in Figure 2, it is a flow chart of a link merging notification method according to an embodiment of the present invention, which specifically includes the following steps:

Step 101, establish the first link;

Step 102, when the first link merges with the existing or newly created second link, generate a response message of the first link including the identification information of the second link;

Step 103, sending a response message. the

In this embodiment, by generating a response message of the first link including the identification information of the second link merged with the first link, the receiver can be notified of the merger of the first link, avoiding interruption of data transmission, and improving the performance of data transmission. the

The method for notifying link combination in this embodiment takes the DRNC notifying the SRNC of link combination as an example, and introduces the technical solution in this embodiment. the

In order to enable the SRNC to clearly know the merging situation of the DRNC side links, in this embodiment, the response message of the first link sent by the DRNC to the SRNC includes the identification information of the second link, and notifies the SRNC of the merging situation. The response message may be a radio link establishment response message, or a radio link establishment failure response message, or a radio link addition response message, or a radio link addition failure response message, or a radio link reconfiguration preparation completion message. In this embodiment, both the first link and the second link are EDCH links, that is, the first EDCH link and the second EDCH link. the

The identification information of the second EDCH link may be an EDCH link identification. Specifically, the merged EDCH link identification field can be added in the "diversity indication selection" field of the response message, and the "RL ID" (link identification) field and the DCH response information field of the merged field for versions above 25.423 Release 6 The merged EDCH link identifier field is added between them, and the merged EDCH link identifier field is added before the DCH response information field that does not merge. As shown in Table 4, it is the "diversity indication selection" field in the response message. the

Table 4. "Diversity Indication Selection" field in the response message

Field Name state Links to detailed instructions ＞Diversity instruction selection m the ＞＞Merge the the ＞＞＞RL ID m 9.2.1.49 ＞＞＞Merge EDCH RL ID o the ＞＞＞DCH response information o 9.2.1.16A ＞＞＞E-DCH FDD response information o 9.2.2.4C ＞＞Do not merge or first link the the ＞＞＞＞Merge EDCH RL ID o the ＞＞＞DCH response information m 9.2.1.16A ＞＞＞E-DCH FDD response information m 9.2.2.4C

As shown in Table 4, "M" in the "Status" column indicates that the cell is mandatory, and "O" indicates that the cell is optional. the

Add a merged EDCH link identifier (merged EDCH RL ID) (as shown in italics in Table 4) field between the "RL ID" field of the merged field and the DCH response information field. The merged EDCH RL ID field is added before the response information field. Wherein the combination field and the non-combination or the first link field do not coexist, when there is a second EDCH link combined with the first EDCH link, the response message of the first EDCH link includes the combination field; when not When there is a second EDCH link, the response message of the first EDCH link includes a non-combined or first link field. the

When adopting the response message of the defined fields in Table 4, the link merging situation notification method in the embodiment of the present invention is specifically: establishing the first EDCH link at the DRNC side; The second EDCH link uplink merges, if so, then write the link identification of the second EDCH link into the above-mentioned increased combined EDCH RL ID field, generate the first EDCH link including the link identification of the second EDCH link The response message, and then send the response message to the SRNC side. the

For example, on the DRNC side, assuming that three links are established, namely the A-th link, the B-th link, and the C-th link, where the A-th link and the B-th link belong to the same NodeB, then the A-th link The road is combined with the uplink EDCH link of the B-th link, but neither is combined with the uplink EDCH link of the C-th link. Before sending a response message to the SRNC through the B link, the B link is the first EDCH link, and the DRNC judges whether there is a combined link of the B link, and judges that the A link is a combined link, that is, the first EDCH link The A link is the existing second EDCH link, then write the link identification (EDCHRL ID) of the A link in the combined EDCH RL ID field added in the response message of the B link; if the response If the link identifier of link A is written in the message, the corresponding EDCH FDD response information cannot be carried in the EDCHFDD response information field in the response message. the

In the above example, if the A-th link is the first link on the DRNC side, before sending a response message to the SRNC through the A-th link, the A-th link is the first EDCH link, and it is determined that the A-th link is If the first link established on the DRNC side indicates that there is no second EDCH link merged with the A-th link, then the response message of the A-th link includes the No Merge or First Link field, and the No Merge Or the combined EDCH RL ID field in the first link field does not carry any information, but carries the corresponding EDCH FDD response information in the EDCHFDD response information field, and the EDCH FDD response information further carries the binding identifier and transport layer address. the

In this embodiment, the combined link identification field can also be added by adjusting each field in the response message, as shown in Table 5, which is the "diversity indication selection" field and the "EDCH diversity indication selection" field in the response message. the

Table 5. "Diversity Indication Selection" field and "EDCH Diversity Indication Selection" field in the response message

Field Name state Links to detailed instructions ＞Diversity instruction selection m the ＞＞Merge the the ＞＞＞RL ID m 9.2.1.49 ＞＞＞DCH response information o 9.2.1.16A ＞＞Do not merge or first link the the ＞＞＞DCH response information m 9.2.1.16A ＞ EDCH diversity indication selection o the ＞＞Merge the the ＞＞＞RL ID m 9.2.1.49 ＞＞＞E-DCH FDD response information o 9.2.2.4C ＞＞Do not merge or first link the the ＞＞＞E-DCH FDD response information m 9.2.2.4C

As shown in Table 5, the related channel information of DCH and EDCH is expressed separately, the "diversity indication selection" field carries the combination information of DCH, and the "EDCH diversity indication selection" field carries the combination information of EDCH. The meaning of the "diversity indication selection" field is the same as that of the prior art, and will not be described in this embodiment. The "EDCH diversity indication selection" field includes a combination field and a non-combination or first link field, wherein the combination field includes a link identification field and an EDCH FDD response information field, and the non-combination field includes an EDCH FDD response information field. The combination field and the non-combination or first link field do not coexist. When there is a second EDCH link combined with the first EDCH link, the response message of the first EDCH link includes the combination field; when there is no For the second EDCH link, the response message of the first EDCH link includes the No Merge or First Link field. the

When adopting the response message of the defined field in Table 5, the link merging situation notification method in the embodiment of the present invention is specifically: establishing the first EDCH link at the DRNC side; The second EDCH link uplink of the second EDCH link is combined, if so, then the link identification of the second EDCH link is written into the RL ID field of the above-mentioned combination field, and the first EDCH link including the link identification of the second EDCH link is generated Response message, and then send the response message to the SRNC side. the

Specifically, when the first EDCH link is merged with the second EDCH link, the response message of the first EDCH link includes a merge field, and the link identification of the second EDCH link is written into the RL ID in the merge field Field, at this time, the EDCH FDD response information field in the combination field does not carry any information; when the first EDCH link is not combined with the second EDCH link, the response message of the first EDCH link includes the non-combination field, and does not The EDCH FDD response information field in the merge field carries the corresponding EDCH FDD response information. the

As shown in Figure 3, it is a flow chart of the method for notifying link merging in Embodiment 2 of the present invention. In this embodiment, the identification information of the second EDCH link may be a binding identifier and a transport layer address, a binding identifier and a transport layer address. The address is usually included in the EDCH FDD response information, then this embodiment specifically includes the following steps:

Step 201, establish the first EDCH link at the DRNC side;

Step 202, judging whether the newly-built first EDCH link is combined with the existing or newly-built second EDCH link uplink, if so, then perform step 203; otherwise, perform step 204;

Step 203, write the binding identifier and the transport layer address carried in the response message of the second EDCH link into the response message of the first EDCH link, and generate the binding identifier and the transport layer address including the second EDCH link The response message of the first EDCH link;

Step 204, when the first EDCH link is not combined with the second EDCH link, or when the first EDCH link is the first link on the DRNC side, combine the binding identifier of the first EDCH link itself with the transport layer The address is written into the response message of the first EDCH link, and the response message of the first EDCH link including the binding identifier of the first EDCH link and the transport layer address is generated. the

In the prior art, if the first EDCH link is merged with the second EDCH link, the response message of the first EDCH link does not carry the binding identifier and transport layer address; if the first EDCH link is not combined with the second EDCH link Links are merged, and the response message of the first EDCH link carries its own binding identifier and transport layer address. Therefore, the processing method of the existing protocol is to judge whether the response message carries the binding identifier and transport layer address. There is an EDCH link merged with the first EDCH link; in this embodiment, no matter whether there is an EDCH link merged with the first EDCH link, the response message of the first EDCH link carries the binding identifier and transmission Layer address, this embodiment enables the SRNC side to accurately know the combination of the first EDCH link on the DRNC side. the

The link merging situation notification method in the embodiment of the present invention provides a solution for notifying the merging situation in the response message, which can enable the SRNC side to know the merging situation of each link on the DRNC side, thereby avoiding serious threats caused by interruption of data transmission The problem of communication quality improves the performance of data transmission. the
