Description

Method for reporting and obtaining multi-carrier frequency capability of user equipment

technical field

The present invention relates to code division multiple access communication technology, more specifically, the present invention relates to a kind of time division synchronous code division multiple access (TD-SCDMA, Time Division-Synchronization Code Division Multiple Access) multi-carrier frequency system reports, obtains user equipment Multi-carrier frequency capability and radio resource allocation method.

Background technique

At present, mobile communication has been developed to the third generation of mobile communication (3G, Third Generation). TD-SCDMA is one of the three main standards of the third generation mobile communication approved by the International Telecommunication Union (ITU, International Telecommunication Union) in May 2000 and by 3GPP in March 2001. As a 3G standard of time-division multiplexing, TD-SCDMA is regarded as a time-division multiplexing technical solution with a low chip rate (1.28MCps, 1.28 megachips/second) in the ITU standard.

Like other mobile communication systems, in order to meet the ever-increasing demands of the mobile communication market, the TD-SCDMA system also needs to use multiple carrier frequency coverage in the same sector/cell to increase the system capacity.

In order to achieve multi-carrier frequency coverage, the existing technology adopts a method of adding several auxiliary carrier frequencies to one main carrier frequency, that is, only one carrier frequency of a cell/sector is used to transmit pilot and broadcast information, and other carrier frequencies are used as auxiliary carriers. Frequency, a cell must have one and only one main carrier frequency, multiple frequency points use a common broadcast, the detailed scheme is as follows:

For each sector, one of the allocated n frequency points is determined as the main carrier frequency, and in the same sector, DwPTS and broadcast information (TS0) are only sent on the main carrier frequency. When establishing a cell, it is necessary to clearly indicate the main carrier frequency so that the Node B can determine which frequency to send the broadcast on, and the frequency point information needs to be added to the channel configuration message so that the terminal and the Node B can obtain relevant content.

In the current multi-carrier frequency system, there are still a large number of user equipment that do not support multi-carrier frequency. Therefore, the multi-carrier frequency system must also be compatible with user equipment (UE, UserEquipment) that currently does not support multi-carrier frequency. The network side acquires Whether a UE has the ability to support multiple carrier frequencies is very important.

Generally, in the current 3GPP specification and TD-SCDMA industry standard, the UE mainly carries capability information and reports it to the network side in the following three ways:

● A radio resource control connection establishment complete message;

● User equipment capability information message;

● The container Container from the source radio network controller to the target radio network controller contains SRNC-RelocationInfo or InterRATHandoverInfo.

In addition, a small amount of access layer version capability information is carried to the network side in the RRC connection establishment request message.

Although the above technical solution can realize the transmission of part of the capability information of the user equipment to the network side, it still has the following disadvantages:

First of all, the UE capability message does not carry multi-carrier frequency capability information, and the network side cannot correctly allocate radio resources to the UE after receiving the message. For example, in the above technical solution, when the UE initially accesses, it sends The first message (RRC connection request message) does not indicate whether the UE supports multiple carrier frequencies, and the network side cannot judge whether the UE can be assigned to the auxiliary carrier frequency;

Secondly, there is no information indicating whether the UE supports multiple carrier frequencies in the subsequent UE capability information message, and the network side cannot judge whether the UE can support multiple carrier frequencies, which affects the radio resource allocation strategy during the handover process of the network side;

Thirdly, when a UE migrates across systems or across RNCs, there is no information indicating whether the UE supports multiple carrier frequencies in the container from the SRNC to the TRNC, and the network side cannot judge whether the UE supports multiple carrier frequencies, which affects the network's emphasis on wireless resources during the positioning process. allocation strategy.

Detailed ways

The present invention is applied in the TD-SCDMA system. By modifying the content of the user equipment capability message, the multi-carrier frequency capability parameter of the user equipment is added in the user equipment capability message, so as to realize reporting the multi-carrier frequency capability supported by the user equipment to the network side , with minor changes to the existing protocol and simple implementation.

Referring to FIG. 1 , this figure is a flowchart of a method for reporting multi-carrier frequency capability of a user equipment according to the present invention.

Firstly, in step 10, the content of the user equipment capability message is expanded, and the multi-carrier frequency capability parameter of the user equipment is added. During specific implementation, the user equipment capability message can be any available capability message, but in order to ensure the consistency of the protocol, it is better to use existing messages for extension, such as RRC connection establishment message, user equipment capability information message, etc. .

Then, in step 11, the user equipment sends the extended capability message to the radio network controller, and the message carries the multi-carrier frequency capability of the user equipment, so as to report the multi-carrier frequency capability of the user equipment to the network side.

How to extend the user equipment capability message will be described in detail below with a specific embodiment. In this embodiment, two methods can be used for extension.

The first extension method: adding multi-carrier frequency capability parameter information to an existing information element of the user equipment capability message, which will be described with a specific example below.

The second extension method: adding a new multi-carrier frequency capability parameter information element representing the multi-carrier frequency capability in the user equipment capability message. Specific examples are used below to illustrate.

First, the first extension method is described. In this embodiment, it is realized by modifying the content of the following user equipment capability message:

During the establishment of the radio resource control connection by the user equipment, the radio resource control connection request message reported by the user equipment; or

During the process of querying user equipment capabilities by the network, the user equipment capability information message reported by the user equipment; or

During the relocation process of the serving radio network controller, the wireless information contained in the "transparent container sent from the source radio network controller to the target radio network controller" in the relocation request message sent by the source radio network controller to the target radio network controller Access capability (UE radio access capability) cell.

For the above RRC CONNECTION REQUEST message in the process of establishing a radio resource control connection for the user equipment, part of the content of the RRC CONNECTION REQUEST message is shown in Table 1.

Table I

Among them, this embodiment uses the existing information element "Access stratum release indicator" to carry the multi-carrier frequency capability supported by the UE, and adds an enumeration item in the information element (IE, Information Element) to indicate whether the UE Support multiple carrier frequencies (the name of the new enumeration item depends on the situation, such as "REL-4-mnlticarrier" in the table), and correspondingly, the corresponding ASN text needs to be modified as follows:

--rel-4-multicarrieris for TDD only

AccessStratumReleaseIndicator::=ENUMERATED{

rel-4, rel-4-multicarrier, spare14, spare13,

spare12, spare11, spare10, spare9, spare8,

spare7, spare6, spare5, spare4, spare3,

spare2, spare1}

If the UE selects "rel-4-multicarrier", it means that the UE supports multi-carrier frequencies, otherwise it means that the UE does not support multi-carrier frequencies.

The following briefly explains how the UE reports the multi-carrier frequency capability to the network side during the process of establishing a radio resource control connection of the user equipment. Referring to Figure 2, when the UE sends the RRC connection request message of the RRC connection request, it includes the multi-carrier frequency capability supported by the UE. In this embodiment, the "Access stratum release indicator" in the RRC connection request message includes the multi-carrier frequency capability supported by the UE. In actual implementation, other IEs can also be used to carry the multi-carrier frequency capability supported by the UE according to the specific situation. As long as the message format is preset, the RNC can obtain it from the corresponding IE according to the preset message format. The multi-carrier frequency capability supported by the UE is sufficient, and is not limited to the "Access stratum release indicator". Currently, the protocol has 15 blank values for subsequent use, but the present invention occupies one blank value to indicate the multi-carrier frequency capability, indicating that there are 14 blank values for subsequent use.

For the user equipment capability information message reported by the user equipment during the user equipment capability query process on the network, part of the content of the user equipment capability information message is shown in Table 2

Table II

The IE also indicates the release of the RRC transfer syntax supported bv the UE..

Similarly, in this embodiment, the existing information element "Access stratum release indicator" of the user equipment capability information message can be used to carry the multi-carrier frequency capability supported by the UE, and a new information element (IE, Information Element) can be added The enumeration item indicates whether the UE supports multi-carrier frequency (the name of the new enumeration item depends on the situation, such as "REL-4-multicarrier" in the table), and correspondingly, the ASN text of the information element needs to be modified as follows:

--rel-4-multicarrier is for TDD only

AccessStratumReleaseIndicator::=ENUMERATED{

rel-4, rel-4-multicarrier, spare14, spare13,

spare12, spare11, spare10, spare9, spare8,

spare7, spare6, spare5, spare4, spare3,

spare2, spare1}

If the UE selects "rel-4-multicarrier", it means that the UE supports multi-carrier frequencies, otherwise it means that the UE does not support multi-carrier frequencies.

Referring to Figure 3, this figure shows that in the process of user equipment capability query, the information element "access stratum release indicator" Access stratum release indicator of the user equipment capability information message carries the multi-carrier frequency capability supported by the UE, and reports the UE to the network side The process of multi-carrier frequency capability.

As shown in the figure, first, the RNC sends a capability inquiry request (UE Capability Inquiry) to the UE; then, the UE responds to the request and returns a UE Capability Information message (UE Capability Information); finally, the RNC sends back a UE Capability Information Acknowledgment message (UE Capability Information Confirm).

The "UE radio access capability" information element is included in the "UE Capability Information" message, and the modification of the "UE radio access capability" information element is consistent with Table 2, indicating the multi-carrier frequency capability of the UE. When the UE sends the UE capability information message, it can carry and report the multi-carrier frequency capability supported by the local end to the RNC in the message.

For the relocation process of the serving radio network controller, the "transparent container sent from the source radio network controller to the target radio network controller" in the relocation request message sent by the source radio network controller to the target radio network controller can also be modified to include The "access stratum version indication" Access stratum release indicator of the user equipment radio access capability (UE radio access capability) information element is realized, and will not be described in detail here, but only how to report the message to the RNC through the relocation process.

Referring to Fig. 4, this figure is the relocation process of RNC.

Taking the existing cell Access stratum release indicator as an example, first, when the source RNC sends a RELOCATION REQUEST message to the target RNC, the Access The stratum release indicator carries the multi-carrier frequency capability supported by the UE. In the same principle, which IE of the specific message is used to store the multi-carrier frequency capability supported by the UE. As long as the message format is preset, the RNC can follow the preset It is only necessary to obtain the switching mode supported by the UE from the corresponding IE in a predetermined message format, and it is not limited to "Access stratum release indicator".

It should be noted that the name of the new enumeration item used in the existing cell Access stratum release indicator and the location of the new enumeration item can be determined according to the actual situation

The second way to modify the user equipment message is described below, that is, to add a new multi-carrier frequency capability parameter information element representing the multi-carrier frequency capability in the user equipment capability message, and the above three user equipment capability messages are taken as examples below illustrate.

For the radio resource control connection request message reported by the user equipment during the establishment of the radio resource control connection by the user equipment, the RRC CONNECTION REQUEST message adds the information content of the multi-carrier frequency capability parameter information element as shown in Table 3

Among them, this embodiment adds a new information element "multi-carrier indicator" MultiCarrier Indicator to carry the multi-carrier capability supported by the UE. Correspondingly, the ASN text needs to be modified accordingly:

For the user equipment capability information message reported by the user equipment during the user equipment capability query process on the network, the message content of the newly added multi-carrier frequency capability parameter information element is shown in Table 4

In addition, in the present invention, during the relocation process of the serving radio network controller, the "source radio network controller sends to the target radio network The newly added multi-carrier frequency capability parameter information element in the source radio network controller information (SrncRelocation) or intersystem handover information (interRATHandoverInfo) contained in the "controller transparent container" will not be described in detail here.

For the RRC connection request message or the user equipment capability information message and the "transparent container sent by the source radio network controller to the target radio network controller" contained in the above-mentioned newly added multi-carrier frequency capability parameter information element and the relocation request message. The process of reporting the multi-carrier frequency capability of the UE in each process of the network controller information (SrncRelocation) or the inter-system handover information (interRATHandoverInfo) can refer to the above-mentioned Figure 2, Figure 3 or Figure 4, the difference lies in the multi-carrier frequency capability of the UE It is carried by adding a new cell, which will not be described in detail here.

Based on the above method for reporting the multi-carrier frequency capability, the present invention also provides a relatively simple method for the network side to accurately obtain the multi-carrier frequency capability of the UE. The method for obtaining the multi-carrier frequency capability of the user equipment in another aspect of the present invention will be described below.

Referring to FIG. 5, this figure is a flow chart of the method for obtaining the multi-carrier frequency capability of the user equipment according to the present invention, which mainly includes the following steps:

Step 20, expand the content of the user equipment capability message, and increase the multi-carrier frequency capability parameter of the user equipment. The specific expansion method refers to the foregoing description, and will not be described in detail here;

Step 21, the user equipment sends the extended capability message to the radio network controller. In actual implementation, the message may or may not carry the multi-carrier capability parameter;

Step 22, the radio network controller detects the extended capability message sent by the user equipment, and judges whether the extended capability message carries a multi-carrier frequency capability parameter, and if it does not carry a multi-carrier frequency capability parameter, proceed to step 25, Otherwise, continue to step 23;

Step 23, the radio network controller continues to judge whether the multi-carrier frequency capability parameter carried in the capability message supports multi-carrier frequency, if so, perform step 24, otherwise, perform step 25;

Step 24, the wireless network control determines that the user equipment supports multiple carrier frequencies;

Step 25, the radio network controller determines that the user equipment does not support multiple carrier frequencies.

During specific implementation, other methods may also be used to obtain the multi-carrier frequency capability of the user equipment, which will not be described in detail here.

In addition, after obtaining the multi-carrier capability of the UE on the network side, related operations can be performed according to the multi-carrier capability of the UE. For example, in the RRC CONNECTION REQUEST message and UE CAPABILITY INFORMATION, the UE reports whether Multiple carrier frequencies are supported, so that the RNC can allocate resources according to UE capabilities. For example, UEs that support multiple carrier frequencies can allocate auxiliary carrier frequency resources, and UEs that do not support multiple carrier frequencies can only allocate primary carrier frequency resources.

When migrating across systems or across RNCs, the target RNC can know whether the UE supports multiple carrier frequencies through the newly added information element MultiCarrier Indicator in the Container from SRNC to TRNC, and handle resource allocation accordingly.

The following uses a specific example to describe how to continue to allocate radio resources of the user equipment according to the above method.

Referring to FIG. 6 , this figure is a flowchart of a specific embodiment of a method for allocating radio resources of a user equipment according to the present invention.

In the method, the aforementioned method for obtaining the multi-carrier frequency capability of the user equipment (step 30-step 35) is applied, and its further improvement lies in adding two steps, which are described as follows:

After the radio network controller determines that the user equipment supports multiple carrier frequencies in step 34, in step 36, the radio network controller assigns the user equipment to the main carrier frequency or the auxiliary carrier frequency according to the multi-carrier frequency capability of the user equipment, and The message carries multiple carrier frequency information to the user equipment;

In addition, after the radio network controller determines that the user equipment does not support multiple carrier frequencies in step 35, in step 37, the radio network controller assigns the user equipment to the main carrier frequency or the auxiliary carrier frequency according to the single carrier frequency capability of the user equipment, And only carry the assigned carrier frequency information to the user equipment in the downlink message.

To sum up, the present invention is based on the existing user equipment capability message, which is extended to carry the multi-carrier frequency capability of the user equipment and reported to the network side, and the RNC on the network side can allocate resources according to the capabilities of the UE. Multiple carrier frequency resources can be allocated, and only single carrier frequency resources are allocated to UEs that do not support multiple carrier frequencies.

When migrating across systems or across RNCs, through the newly added IEMultiCarrier Indicator in the Container from SRNC to TRNC, the target RNC can know whether the UE supports multiple carrier frequencies, and handle resource allocation accordingly.

Since the existing protocol message structure is basically not changed, no matter whether the existing IE or the newly added IE is used, it fully meets the compatibility requirements of the protocol, ensuring that UEs that do not support multi-carrier frequencies can also operate in multi-carrier frequency cells. access.

The above descriptions are only preferred embodiments of the present invention, and do not constitute a limitation to the protection scope of the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the claims of the present invention.
