Problems solved by technology

However, the current agreement stipulates that the above IEs are all mandatory. In this case, the following problems may occur: (1) Since the corresponding DCH information cannot be provided, if the sending end is constructing NBAP / RNSAP wireless link establishment or addition and its response If the relevant IE is not provided during the message, the ASN.1 encoding will fail and the message cannot be sent: (2) If the sender uses redundant information or uses HS in constructing NBAP / RNSAP wireless link establishment or addition and its response message -The logical channel information carried on the DSCH and E-DCH fills the relevant IEs, and these IEs contain error or redundant information. On the one hand, this increases the redundancy of interface transmission information. On the other hand, the receiving end is processing When these erroneous information will cause state machine exception; And (3) if the wireless link establishment or increase and its response message of constructing NBAP / RNSAP do not contain above-mentioned IE at sending end, then can't construct correct message, because these IE It is a mandatory IE. When the receiving end decodes the response message with ASN.1 and finds that the IE does not exist, it will send an error message and enter the local exception processing state.
In addition, since the content of the DCHInformation Response IE included in the success / failure response process is the resource information configured for the transmission bearer corresponding to each DCH, such as Binding ID IE, Transport Layer Address IE, etc., a possible consequence is that CRNC or SRNC Attempt to establish a transmission bearer for the DCH between CRNC and Node B, and SRNC and DRNC, resulting in invalid transmission bearer establishment process or redundant transmission bearer establishment, wasting resources

[0085] In the first embodiment of the present invention, a method for processing a wireless link establishment request based on FDD mode is provided. The first embodiment of the present invention will be described below with reference to FIG. A flowchart of a method for processing a wireless link establishment request according to the first embodiment of the present invention.

[0086] The wireless link establishment request processing method according to the first embodiment of the present invention includes the following steps:

[0087] Step S502: SRNC (source radio network controller) constructs the RNSAP radio link establishment request message (first message) and encodes it, wherein, the presence attribute (Presence) of the specific information element in the RNSAP radio link establishment request message ) is "optional" or "conditional";

[0088] Step S504: In response to the RNSAP radio link establishment request message, DRNC (drift radio network controller) construct...

Abstract

The present invention provides a method for establishing the wireless link or increasing the demand processing based on a FDD model, which comprises the following procedures: the first procedure is that a source wireless network controller constructs a RNSAP first message and performs a coding to the RNSAP first message; the second procedure is to respond to the RNSAP first message, and that a drift wireless network controller constructs the RNSAP first message and performs the coding to the RNSAP first message; the third procedure is to respond to a NBAP first message and that a node B constructs a NBAP second message and performs the coding to the NBAP first message; and the forth procedure is to respond to the NBAP second message and that the drift wireless network controller constructs the NBAP second message and performs the coding to the NBAP second message; wherein, in the all procedures, the existence attribute of a relevant specific message element is ''optional'' or ''conditional'', the E-DCH is adopted by the upstream according with the condition and the HS-DSCH is adopted by the downstream during the coding process, the specific information element can not be comprised under the condition of DCH not being adopted. The present invention also provides a device for establishing the wireless link or increasing the demand processing based on the FDD model.

Description

technical field [0001] The present invention relates to the field of communications, and more particularly, to a method and device for processing a wireless link establishment or addition request, Background technique [0002] HSDPA (High Speed ​​Downlink Packet Access) is a packet-based data service of 3GPP (Third Generation Partnership Project) that enhances the downlink part of mobile data transmission. HSDPA is used inside the WCDMA downlink (5MHz bandwidth), providing a maximum data transmission rate of up to 10Mbps, and the actual average rate is between 4Mbps and 8Mbps. Further upgrades are expected to increase these rates to 20Mbps. The goal of HSDPA is to provide higher data rates and consistent QoS (Quality of Service). It also has the ability to transmit voice and data simultaneously to the same receiver. [0003] Enhanced Uplink Dedicated Channel (E-DCH), also known as HSUPA (High Speed ​​Uplink Packet Access), is introduced in Release 6 after 3GPP (Third Gene...
