Abstract

The application discloses a terminal UE access control method. After determining the terminal protocol version of terminal UE according to an access request sent by the terminal UE, an RNC (Radio Network Controller) judges whether the terminal protocol version is higher than the highest protocol version supported. If the terminal protocol version is higher than the highest protocol version supported, the UE is redirected under instruction according to the LTE capacity of the UE, the reason why the access request is triggered, a blind redirection switch and the neighborhood of a cell which the UE requests to access, or the access request is processed in accordance with the highest protocol version. The success rate of RRC access and the success rate of relocation are improved, user perception is ensured, and the investment of operators is protected.

Description

technical field

[0001] The present application relates to the field of communication technology, and in particular to a terminal UE access control method. The present application also relates to a radio network controller RNC. Background technique

[0002] Thanks to the characteristics of high network speed and high spectrum utilization rate, 4G (fourth generation mobile communication technology) LTE (Long Term Evolution, long-term evolution) is expected to become the main network for carrying data services in the future, but the current LTE network only supports The data service and the voice service need to fall back to the GSM (Global System for Mobile Communication, Global System for Mobile Communication) network through the CSFB (Circuit Switched Fallback) method.

[0003] When the current 2G / 3G / 4G network is interoperating, the GSM network and the LTE network do not have a direct neighbor relationship. They are both configured with the 3G network neighbor relationship...

Examples

Embodiment Construction

[0052] The existing network RNC (Radio Network Controller, radio network controller) usually allocates resources according to the terminal version number indicated by the access message, and organizes a corresponding version message to be sent to the terminal for a newly accessed terminal. For example, the terminal uses REL-n (n= 3, 4, 5, 6, 7, 8, 9, ...), the RNC organizes a message of the corresponding REL-n version to the terminal, and the terminal version is included in the transparent container ( ToTargetRNC_Container), taking RRC access and relocation entry as an example, during the RRC access process, the terminal sends an RRC CONNECTION REQUEST message to UTRAN, and the RNC decodes the ASN of the message to extract the IE (Information element, message element ), the IE indicates the reason for the terminal to send the RRC request, the version of the terminal protocol, and the capability of the terminal. The RNC saves these information, and then allocates corresponding l...
