Problems solved by technology

If the wireless link is required to support DCH and E-DCH at the same time, the above two IEs will be included in the returned message, and the message will be processed normally in SRNC and DRNC; if the wireless link only supports DCH, it will appear The following problems: (1) Since the E-DCH FDD Information Response IE is a mandatory IE (as shown in Figure 3, the presence is M (mandatory)), and the DRNC cannot provide the necessary content to construct the IE, which will result in a message ASN. 1 Encoding fails, unable to return correct response information to SRNC; (2) If DRNC uses redundant information to forcibly fill E-DCHFDD Information Response IE in the returned message, then this IE contains error and redundant information, so On the one hand, the redundancy of the interface transmission information is increased; on the other hand, when the SRNC at the receiving end processes the error information in the E-DCH FDD Information Response IE, the state machine will be abnormal; if the message returned by the DRNC does not contain E -DCHFDD Information Response IE, the correct response message cannot be constructed. Since this IE is a mandatory IE, SRNC finds that this IE does not exist when ASN.1 decoding the response message, and will send an error

Abstract

The present invention provides a method for establishing the demand processing of a wireless link, which comprises the following procedures: the first procedure is to respond to a first message from a source wireless network controller, a drift wireless network controller establishes the relevant resources according to the requirement of the source wireless network controller, wherein, an enhanced-type upper dedicated channel is not comprised in the resource; the second procedure is that the drift wireless network controller comprises a second message, and the third procedure is that the drift wireless network controller performs a ASN. 1 code to the second message, wherein, the existence attribute of a specific message element in the second message is ''Optional'' and the coding of the specific information element can not be performed during the coding process. The present invention realizes the following technical effects through the technical proposal: while the information message redundancy between the SRNC and the DRNC is decreased, the establishment of a request process of the wireless link is processed exactly, to avoid the failure of an ASN.1 decoding and other problems, and thereby normally completing the establishment process of the wireless link.
