Technical field

The present invention relates to the field of wireless communications, and in particular, to a method, a terminal, and a network side device of a wireless access system.

Background technique

With the development of communication technologies, future communication networks, as well as the current Global System of Mobile Communication (GSM), Wideband Code Division Multiple Access (WCDMA), wireless LAN or Communication networks such as WLAN (Wireless Local Area Network) use a variety of radio access technologies (RATs), but different RATs have different characteristics, such as different RAT costs and data rate support capabilities. Different, different quality of service (QoS), different instantaneous load acceptance capabilities, etc.

In order to maintain the advantages of different RATs, more and more terminals have multiple RAT capabilities, which makes communication between different RATs more convenient. When the terminal switches from one RAT to another, it needs to perform pre-negotiation with the target RAT, also called "capability interaction". Only when the capability interaction meets certain conditions, the terminal initiates a relocation function to the target RAT. When the terminal performs pre-negotiation with the target RAT, the security capability provided by the target RAT, the QoS mechanism provided by the RAT, the network load of the target RAT, the maximum rate supported by the target RAT, and the wireless load of the target RAT are required to obtain information. The update period is inconsistent. For example, information such as security capability, maximum rate, and QoS mechanism does not change over a long period of time. It is called semi-static capability information. Information such as network load and wireless load changes rapidly over time. Call it dynamic capability information.

The prior art provides a method for relocating a RAT, which is directed to a single

RAT, since the source RAT and the target RAT have consistent semi-static capability information, there is no interaction and negotiation of semi-static energy information between the RATs, and the dynamic capability information is also based on dynamic capability information between different sites in the RAT. Switching the terminal from the source RAT to the target RAT completely adopts a forward mode, that is, the terminal evaluates the signal strength of the surrounding RAT, and initiates random access to the RAT with stronger signal. Positioning, and using the RAT with the stronger signal as the target RAT.

In the prior art, the RAT is selected as the target RAT according to the signal strength of the RAT, and whether the terminal is accepted by the target RAT is determined by the resource allocation and the establishment of the radio bearer, thereby reducing the probability that the terminal successfully accesses the target RAT, thereby reducing the probability of the terminal successfully accessing the target RAT.

detailed description

In order to improve the probability of the terminal successfully accessing the target RAT, the embodiment of the present invention provides a method for relocating a wireless access system, where the method includes:

Matching the capability information of the neighboring wireless access system with the capability information corresponding to the terminal, where the capability information includes semi-static capability information and/or dynamic capability information; determining candidate target wireless access of the terminal relocation according to the matching result system.

When the matching is successful, the neighboring wireless access system is used as a candidate target wireless access system for terminal relocation.

The technical solutions of the embodiments of the present invention will be described below in conjunction with the accompanying drawings.

Embodiment 1 A method for relocating a wireless access system, the method flow is as shown in FIG. 1, and includes the following steps:

Step 101: The neighbor RAT transmits part of the capability information to the source RAT through the backbone network, so that the source RAT interacts with the terminal for the capability information of the neighboring RAT. The partial capability information is mainly semi-static capability information, which may be collected by the source RAT during the RAT establishment process, and updated when the capability changes.

The RAT currently camped on by the terminal is generally referred to as the source RAT, and the RATs around the source RAT are referred to as neighbor RATs, which may become candidate target RATs for terminal relocation.

Step 102: The neighbor RAT notifies the dynamic capability information to the broadcast or other manner through the air interface. Terminal.

Step 103: The terminal matches its dynamic capability information with the dynamic capability information of the neighboring RAT. If the dynamic capability information is successfully matched, the terminal sends a capability interaction request message requesting the capability negotiation with the neighboring RAT, where the capability interaction request message carries the semi-static capability information of the terminal, and the source RAT provides the terminal with the semi-static capability information of the neighboring RAT. The semi-static capability information is matched.

It should be noted that the capability interaction request message may be a dedicated signaling message or an in-band message, where the dedicated signaling message is carried by independent signaling, and the in-band message is when the terminal establishes a connection in the same-origin RAT. Or carried to the source RAT by signaling when the relocation request is made.

Step 104: The source RAT matches the semi-static capability information of the neighboring RAT with the semi-static capability information corresponding to the terminal, and sends the matching result of the terminal to the neighboring RAT through the capability interaction response message, where the capability matching is successful. The neighbor RAT can serve as a candidate target RAT for terminal relocation. Optionally, when the source RAT sends the capability interaction response message to the terminal, the capability information that the neighbor RAT does not match may be included in the capability interaction response message, including semi-static capability information, and the terminal performs matching and relocation.

It should be noted that the capability interaction response message may be a dedicated signaling message, or may be an in-band message or an implicit signaling information (such as selecting a target RAT when relocating).

In this embodiment, optionally, the capability interaction request message in step 103 may not carry the semi-static capability information of the terminal, and in step 104, the source RAT will not match the capability information of the neighbor RAT, that is, the neighbor RAT semi-static capability information. The capability is sent to the terminal through the capability interaction response message, and the terminal matches the semi-static capability information of the neighbor RAT with its semi-static capability information. Whether the neighbor RAT can be used as the candidate target RAT of the terminal relocation is determined by the result of the matching. When the matching is successful, the neighboring wireless access system is used as the candidate target wireless access system for the terminal relocation.

In this embodiment, the dynamic capability information can be directly sent to the terminal through the air interface, so that the dynamic capability information is timely and effective. In addition, the semi-static capability information is transmitted to the source RAT through the backbone network, thereby reducing the air interface overhead, and at the same time The frequency of static capability information changes is not very high, and the overhead on the backbone network is not large.

Optionally, in the embodiment of the present invention, the dynamic capability information and the semi-static capability information of the neighboring RAT may be sent to the source RAT through the backbone network, and the source RAT matches the capability information of the neighboring RAT with the capability information provided by the terminal. In addition, the source RAT may also receive dynamic capability information of the neighbor RAT and The semi-static capability information is sent to the terminal, and the terminal matches the dynamic capability information and the semi-static capability information of the neighboring RAT with the capability information corresponding to the neighboring RAT.

It is to be noted that the neighboring RAT sends its own semi-static capability information and dynamic capability information to the source RAT through the backbone network, and the terminal sends a capability interaction request message requesting capability negotiation with the neighboring RAT, where the capability interaction request message carries the terminal. The dynamic capability information or the semi-static capability information; the source radio access system matches the capability information of the neighbor RAT with the dynamic capability information or the semi-static capability information of the terminal. If the matching is successful, the matching result and the capability information of the neighbor RAT are not matched. Sending to the terminal, the terminal matches the capability information that the neighbor RAT does not match with the capability information corresponding to the terminal; if the matching fails, the matching result is sent to the terminal.

Optionally, in the embodiment of the present invention, the terminal may forward the dynamic capability information and the semi-static capability information of the neighboring RAT to the terminal directly by the source RAT, and the terminal dynamically forwards the dynamic information of the neighboring RAT to the terminal. The capability information and the semi-static capability information are matched with the semi-static capability information and the dynamic capability information sent by the source RAT.

Optionally, the neighboring RAT may directly notify the terminal of the dynamic capability information and the semi-static capability information by using an air interface, and the terminal may compare the dynamic capability information and the semi-static capability information of the neighboring RAT with the capability information of the neighboring RAT. Make a match. The dynamic capability information of the neighboring RAT is matched with the dynamic capability information corresponding to the terminal, and the semi-static capability information of the neighboring RAT and the semi-static capability information corresponding to the terminal are matched.

It should be noted that, in the embodiment of the present invention, there is no necessary sequence between the steps, and only the related capability information of the neighbor RAT can be received before the terminal performs capability matching with the neighbor RAT, for example, dynamic The capability information and/or the static capability information, or the related capability information of the neighboring RAT and the terminal can be received before the source RAT performs capability matching on the terminal and the neighbor RAT. In addition, when the terminal and the source RAT respectively match the partial capability information, the matching does not have an inevitable sequence, and the terminal may first match, the source RAT is matched, and vice versa.

It can be understood that, in this embodiment, the relocation of the wireless access system can be performed only after the semi-static capability information and the dynamic capability information of the terminal and the neighboring RAT are successfully matched. If the semi-static capability information of the terminal and the neighboring RAT are successfully matched, the radio access system may be relocated. Similarly, after the dynamic capability information of the terminal and the neighboring RAT are successfully matched, the radio access system may be relocated. Embodiment 2 A relocation method of a radio access system, where the method flow is as shown in FIG. 2, specifically including the following steps:

Step 201: The terminal initiates a capability information interaction request message to the neighboring RAT to the source RAT, and requests the capability negotiation with the neighboring RAT.

Step 202: The source RAT initiates a capability information interaction request message to the neighboring RAT, and requests capability negotiation with the neighboring RAT.

Step 203: The neighboring RAT sends a capability interaction response message to the source RAT, where the capability interaction response message carries semi-static capability information and dynamic capability information of the neighboring RAT.

Step 204: The source RAT sends the semi-static capability information and the dynamic capability information of the neighboring RAT to the terminal by using the capability interaction response message, and the terminal matches the dynamic capability information and the semi-static capability information of the neighboring RAT with the capability information corresponding to the terminal, and according to the matching. The result is to determine whether the neighbor RAT can serve as a candidate target RAT for terminal relocation.

In this embodiment, optionally, in step 201, the capability information exchange request information sent by the terminal may carry the capability information of the terminal, and in step 202, the capability information of the terminal is forwarded to the neighboring RAT. In step 203, the neighbor RAT will be the terminal. The capability information matches the capability information of the neighbor RAT, and the matching result is forwarded to the terminal through the source RAT. If the capability information exchange request information sent by the terminal carries the semi-static capability information and the dynamic capability information of the terminal, in step 202, the source RAT may forward part of the capability information of the terminal to the neighbor RAT, where the part of the capability information may be half of the terminal. Static information or dynamic capability information; then, in step 203, the neighbor RAT matches the partial capability information of the terminal with the capability information corresponding to the neighboring RAT, and if the matching fails, the failure result is forwarded to the terminal through the source RAT; if the matching succeeds, the matching will be performed. The result is forwarded to the source RAT, and the source RAT matches the partial capability information that the neighbor RAT does not match with the implemented final capability information corresponding to the terminal, and feeds the result back to the terminal. Optionally, when the neighboring RAT sends the capability interactive response message to the terminal, the neighboring RAT may also carry the semi-static capability information and/or dynamic capability information of the neighboring RAT to the terminal, and the terminal performs matching.

It is to be noted that, in step 201, the capability information exchange request message may carry part of the capability information of the terminal, such as semi-static capability information or dynamic capability information, and in step 202, the partial capability information of the terminal is forwarded to the neighboring RAT; The neighbor RAT completes the matching of the capability information of the neighboring RAT with the neighboring RAT. If the matching fails, the source RAT feeds back the failure result to the terminal; If successful, the matching result and other semi-static capability information or dynamic capability information that do not match are forwarded to the terminal through the source RAT. In step 202, the partial capability information of the terminal may not be forwarded, and the neighbor RAT forwards all the capability information to the source RAT, and the source RAT matches the partial capability information of the terminal with the capability information corresponding to the neighbor RAT. The failure result is fed back to the terminal; if the matching is successful, the matching result and other non-matching semi-static capability information or dynamic capability information are forwarded to the terminal, and the terminal matches other semi-static capability information and/or dynamic capability information that does not match, thereby determining Whether the neighbor RAT is a candidate target RAT.

It can be understood that, in this embodiment, the relocation of the wireless access system can be performed only after the semi-static capability information and the dynamic capability information of the terminal and the neighboring RAT are successfully matched. If all the semi-static capability information of the terminal and the neighboring RAT are successfully matched, the wireless access system may be relocated, or the dynamic capability information of the two parties may be successfully re-located after the matching of the dynamic capability information.

Implementation 3: A method for relocating a wireless access system, the method flow is as shown in FIG. 3, and specifically includes the following steps:

Step 301: The terminal sends a capability interaction request message to the neighboring RAT, requesting capability negotiation with the neighboring wireless access system.

Step 302: The neighbor RAT sends its semi-static capability information and dynamic capability information to the source RAT through the backbone network.

Step 303: The source RAT forwards the capability information of the neighboring RAT to the terminal by using the capability information interaction response message, and the terminal performs capability information matching according to the capability information of the neighboring RAT and the capability information of the terminal, and determines whether the neighbor RAT can be used as the terminal according to the matching result. The candidate target RAT for positioning.

Optionally, the terminal may send all the capability information of the terminal to the source RAT, where the source RAT matches the capability information of the terminal with the capability information of the neighboring RAT.

Optionally, in the embodiment of the present invention, all the capability information of the terminal may be carried in the step 301 to the neighboring RAT. In the step 302, the neighboring RAT matches the capability information of the terminal and the capability information of the neighboring RAT, and the matching result is fed back. To the source RAT, the capability information interaction result is fed back to the terminal through the source RAT.

Optionally, in step 301, part of the capability information of the terminal may be carried to the neighboring RAT. In step 302, the neighboring RAT matches the partial capability information sent by the terminal with the partial capability information corresponding to the neighboring RAT. If the capability matching fails, the result is directly sent to the terminal through the source RAT; The function, the other part of the unmatched semi-static information or dynamic capability information is forwarded to the terminal by the source RAT, and the terminal matches the unmatched semi-static information or the dynamic capability information with the capability information corresponding to itself, and then according to the The matching result determines whether the neighbor RAT can serve as a candidate target RAT.

In this embodiment, the semi-static information and/or the dynamic capability information of the neighboring RAT may be sent to the terminal through the air interface, and the terminal may first complete the matching of the part of the capability information before performing step 301, and then complete the remaining part of the capability through the foregoing process. Matching of information.

It should be noted that there is no inevitable sequence between the steps of the embodiment of the present invention, and it is only necessary to ensure that the related capability information of the neighboring RAT can be received before the terminal performs capability matching with the neighboring RAT, or in the neighboring RAT. The capability information of the terminal can be received before the capability matching between the terminal and the neighbor RAT. In addition, when the terminal and the neighboring RAT respectively match the partial capability information, the matching does not have a certain order, and the terminal can be matched first, and the neighboring RAT is matched, and vice versa.

In order to improve the success rate of the terminal access neighbor RAT and reduce the delay, the neighbor RAT that successfully matches the terminal capability information may reserve uplink or downlink resources for the terminal in advance, and reserve the resource by the source RAT. Send to the terminal, so that the terminal can quickly access the neighbor RAT.

As can be seen from the above, the embodiment of the present invention firstly matches the semi-static capability information and/or the dynamic capability information of the neighboring wireless access system with the capability information corresponding to the terminal, and when the capability information is successfully matched, The adjacent wireless access system is used as a candidate target wireless access system for terminal relocation, thereby improving the probability that the terminal successfully accesses the target wireless access system, thereby reducing the utilization of system resources.

It can be understood that, in this embodiment, the relocation of the wireless access system can be performed only after the semi-static capability information and the dynamic capability information of the terminal and the neighboring RAT are successfully matched. If the semi-static capability information of the terminal and the neighboring RAT are successfully matched, the radio access system may be relocated, or the radio access system may be relocated after the dynamic capability information of the terminal and the neighboring RAT are successfully matched.
