Description

Method and system for service radio network controller to identify transmission bearer capability

Technical field

The present invention relates to the field of communication technologies, and more particularly to a method and system for a service radio network controller to identify a transmission bearer capability.

Background technique

The high-speed uplink packet access technology improves the performance of uplink packet data by means of fast scheduling and physical layer fast retransmission combining. The high-speed uplink packet access technology introduces a new transport channel, an Enhanced Dedicated Channel (E-DCH), which is used to carry user data and is in a single uplink direction. A dedicated media access control (MAC-d) protocol data unit (PDU) is mapped to the enhanced dedicated channel data stream, which is called a dedicated media access control flow (MAC-d). Flow ). A terminal has one or more dedicated media access control flows (MAC-d flows).

In a wireless communication system, an IUR (Interconnection of RNC) interface is an interface used by a radio network controller for signaling and data interaction with other radio network controllers, and is between wireless network subsystems. Interconnected ties.

When a terminal establishes a connection to the radio access network and soft handover occurs on the IUR interface, more than one radio network controller resource is used. Different radio network controllers play different roles at this time:

The serving radio network controller, the radio network controller that maintains the interface of the terminal with the core network, is a serving radio network controller. The service radio network controller is responsible for data transmission between the core network and the terminal and transmission and reception of interface signaling with the core network, is responsible for radio resource control, is responsible for layer 2 processing of the air interface data, and performs basic wireless operation. Resource management operations, such as handover decisions, outer loop power control, and conversion of parameters of radio access bearers to air interface transmission channel parameters; drift radio network controllers, other radio network controllers other than serving radio network controllers, Control the cell used by the terminal, if necessary, the drift radio network controller can perform Macros are grouped together. Unless the terminal uses the common transport channel, the drift radio network controller does not perform layer 2 processing of the terminal plane data, but simply passes the route of the air interface data transparently through the IUR interface to the service radio network controller. There can be more than one drift wireless network controller for one terminal.

The IUR interface provides an uplink enhanced dedicated channel transmission between the drift radio network controller and the serving radio network controller. An IUR interface framing protocol layer data stream corresponds to data carried by a terminal's dedicated media access control flow (MAC-d flow). Therefore, one terminal corresponds to one or more IUR interface framing protocol layer data streams.

In the single-carrier high-speed uplink packet access technology, an IUR interface framing protocol layer data stream is carried by an IUR interface transport bearer (Transport Bearer), and the IUR interface framing protocol layer data stream does not need to carry a carrier identifier. In the multi-carrier high-speed uplink packet access technology, an IUR interface framing protocol layer data stream may be carried by one IUR interface transmission bearer, or may be multiple (the number of carriers of which the number and the multi-carrier are the same) The IUR interface transports bearers to carry. When an IUR interface framing protocol layer data stream is carried by an IUR interface transmission bearer, the IUR interface framing protocol layer data stream must carry a carrier identifier to distinguish the carrier from which the carried data is derived from the air interface. The processing method is called E-DCH UL Flow Multiplexing, which is logically referred to as "shared IUR transport bearer", hereinafter referred to as "shared IUR transport bearer". When an IUR interface framing protocol layer data stream is carried by multiple IUR interface transmission bearers, that is, according to an IUR interface framing protocol layer data stream, data carried in the air interface is derived from the carrier, each carrier source The data is carried on an IUR interface transmission bearer. The data of multiple carrier sources is carried on multiple IUR interface transmission bearers. The number of IUR interface transmission bearers and the number of multi-carrier carriers are the same. The IUR interface is framing the protocol layer data stream. There is no need to carry a carrier identifier. This type of processing is called "Separate IUR Transport Bearer".

The neighboring cell of a certain cell may be in the drift radio network controller, and the drift radio network controller needs to inform the service of the support capability of each functional feature of the cell in the drift radio network controller in a neighboring cell manner. A radio network controller that provides information to the serving radio network controller to make decisions about related functional characteristics, such as whether to use features and how to use the features. The support capabilities of the various functional features of the cell in the present drift radio network controller include: "Upstream Multi-Carrier Capability", which is called "Multi Cell E-DCH Capability" in the industry: It refers to whether the cell supports "Multi Cell E-DCH" and the value is "Support". "Or" does not support". When the value is "supported", it means that the cell supports uplink multi-carrier operation. When the value is "not supported", it means that the cell does not support uplink multi-carrier operation;

"Shared IUR transmission bearer capability", referred to as "E-DCH UL Flow Multiplexing" in the industry: refers to whether the cell supports the "shared IUR transport bearer" processing method, and the value is "support". Or "not supported", when the value is "supported", it means that the cell supports the "shared IUR transport bearer" processing mode, and supports an IUR interface framing protocol layer data stream carried by an IUR interface transport bearer. The IUR interface framing protocol layer data stream must carry the carrier identifier. When the value is "not supported", it means that the cell does not support the "shared IUR transport bearer" processing mode. It does not support an IUR interface. The frame protocol layer data stream is carried by an IUR interface transport bearer, or does not support the operation of carrying the carrier identifier in the IUR interface framing protocol layer data stream;

"Separate IUR Transport Bearer Capability": Refers to whether the cell supports the "separate IUR transport bearer" processing method. The value is "support" or "not supported". When the value is "support", This means that the cell supports the "separate IUR transport bearer" processing mode, and supports one IUR interface framing protocol layer data stream is carried by multiple IUR interface transport bearers (IUR interface transport bearers and multi-carrier carriers) When the value is "not supported", it means that the cell does not support the "separate IUR transport bearer" processing mode, and does not support an IUR interface framing protocol layer data stream is transmitted by multiple IUR interfaces. Bearer (the number of IUR interface transmission bearers and the number of carriers with multiple carriers are the same).

In the prior art, when performing softswitch, the following processing loopholes exist:

In the multi-carrier high-speed uplink packet access technology, each layer carrier has its own independent macro diversity, and performs soft handover independently. Each cell in the macro-switching group that is added to the soft handover may support uplink multi-carrier (Multi Cell E). The -DCH) operating cell may also be a cell that does not support uplink multi-carrier operation, such as a conventional single-carrier cell. For a designated terminal, each soft-switched macro-divided cell of each carrier of the terminal needs to have the same IUR transmission bearer support capability, such as each soft-switching macro-division of each carrier of the terminal. The community supports "minutes The IUR transmission bearer "processing mode, or each cell in the macro-switching of each soft-switching of each carrier of the terminal supports the "shared IUR transmission bearer" processing mode, so that normal soft handover data reordering and merging processing can be performed. Otherwise, the serving radio network controller will not be able to add different IUR transport bearer supporting cells to the soft handoff macro diversity set.

When a cell using a multi-carrier high-speed uplink packet access technology in a drift radio network controller supports uplink multi-carrier, and supports a "separate IUR transport bearer" processing method, but does not support "shared IUR transport bearer" processing. the way. The serving radio network controller wants to perform soft handover on this carrier of the cell, and adds a traditional single-carrier cell in the soft handover macro diversity, and the single-carrier cell does not support the "shared IUR transmission bearer" processing mode. Then, the serving radio network controller cannot join the cell of the conventional single carrier, which greatly affects the system performance, and lacks the macro diversity gain of the soft handover.

Preferred embodiment of the invention

The basic idea of the invention is:

For a traditional single-carrier cell, that is, in a single-carrier high-speed uplink packet access technology, on this carrier, an IUR interface framing protocol layer data stream is carried by an IUR interface transport bearer, and the IUR interface is The carrier identifier is not required to carry the frame protocol layer data stream. Therefore, a traditional single-carrier cell can be considered to support the "separate IUR transport bearer" processing.

For a cell supporting "uplink multi-carrier", the "separate IUR transport bearer" processing method and The "shared IUR transport bearer" processing method is a software processing method that is not rigidly defined by any hardware or radio frequency resources. From a software perspective, the "separate IUR transport bearer" processing and the "shared IUR transport bearer" processing can all be implemented at very low cost. Considering backward compatibility, from the perspective of serving the radio network controller, for this cell, it can be understood as: It can be regarded as supporting the "separate IUR transmission bearer" processing method in the single-carrier pre-technical phase; , can be seen as a further way to support a higher "shared IUR transport bearer". That is, from the perspective of serving the radio network controller, the support of the "separate IUR transport bearer" processing mode can be regarded as a kind of capability that needs to be supported in the single carrier technology phase, and the "shared IUR transport bearer" processing method is adopted. Think of a more advanced, optional support capability that was introduced at the multi-carrier technology stage. Thus, the serving radio network controller can perform soft handover to join the new cell without any obstacles.

That is, for a cell with a traditional single carrier in the macro diversity, the serving radio network controller can control the use of the "separate IUR transport bearer" processing mode. For a cell in which the macro diversity is all supported by the uplink multi-carrier capability, and all the cells supporting the "shared IUR transmission bearer" processing mode, the serving radio network controller may decide to control the use of the "separate IUR transmission bearer" according to a certain algorithm. Or control the use of "shared IUR transport bearer" processing. In this way, the processing loopholes in the prior art can be solved.

In the prior art, for a cell supporting an uplink multi-carrier, there is a theoretical situation in which a "shared IUR transport bearer" processing mode is supported, but a "separate IUR transport bearer" processing method is not supported. However, in practical applications, this scenario does not have any technical value. Therefore, the principle based on the present invention is that the possibility of such a scenario does not exist, that is, all cells need to support the "separate IUR transport bearer" processing method. .

Based on the above idea, the present invention provides a method for a service radio network controller to identify an IUR interface transmission bearer capability, and uses the following technical solutions:

For a cell in the drift radio network controller, if the cell supports "uplink multi-carrier" and supports the "shared IUR transport bearer" processing mode, the serving radio network controller identifies the cell as supporting the use of "separate IUR transport bearer" processing. Mode and support use the "shared IUR transport bearer" processing method; if the cell supports "uplink multi-carrier" but does not support the "shared IUR transport bearer" processing mode, the serving radio network controller identifies the cell as supporting the use of "separate IUR transmission" Undertake "Processing mode, but does not support the use of "shared IUR transport bearer" processing method; if the cell does not support "uplink multi-carrier", the serving radio network controller recognizes that the cell supports the use of "separate IUR transport bearer" processing mode, However, the use of the "shared IUR transport bearer" processing is not supported.

Further, the above method specifically includes the following steps:

In the first step, the serving radio network controller receives, by the drift radio network controller, whether the cell supports "Multi Cell E-DCH Capability" and "Shared IUR Transport Bearer Capability (E-DCH UL Flow Multiplexing) Capability) "Support capability information; The second step, the service radio network controller analyzes the support capability information of "Multi Cell E-DCH Capability" and "Shared IUR Transport Bearer Capability (E-DCH UL Flow Multiplexing Capability) "Support capability information, which in turn identifies the IUR interface transport bearer capability of the cell.

The specific resolution process is as follows:

When the support capability information of "uplink multi-carrier capability" is "support" and the support capability information of "shared IUR transmission bearer capability" is "support", the serving radio network controller identifies the cell as supporting the use of "separate IUR transport bearers". "Processing and support using the "shared IUR transport bearer" processing method;

When the support capability information of "uplink multi-carrier capability" is "support", but the support capability information of "shared IUR transmission bearer capability" is "not supported", the serving radio network controller identifies the cell as supporting the use of "separate IUR transmission". Hosting "processing mode, but does not support the use of "shared IUR transport bearer" processing;

When the support capability information of "uplink multi-carrier capability" is "not supported", the serving radio network controller recognizes that the cell supports the "separate IUR transport bearer" processing mode, but does not support the use of the "shared IUR transport bearer" processing mode. .

In the first step, the cell is in a drift radio network controller.

Further, the cell is a neighboring cell, and the drift radio network controller uses the support capability information of the uplink multi-carrier capability and the shared IUR transmission bearer capability of the cell as the support capability information of the neighboring cell, and notifies the Service wireless network controller.

Further, the drift radio network controller is to "on the cell" through IUR interface signaling The support capability information of the multi-carrier capability and the shared IUR transmission bearer capability is sent to the serving radio network controller. The signaling of the IUR interface capable of transmitting the cell capability indication information is as follows: Uplink signaling transmission indication (UPLINK SIGNALLING TRANSFER) INDICATION ); RADIO LINK SETUP RESPONSE ;

Wireless link setup failure ( RADIO LINK SETUP FAILURE );

Wireless link increase response ( RADIO LINK ADDITION RESPONSE ) ;
