A method and device for selecting a resident carrier

Abstract

The present application discloses a method and equipment for selecting a resident carrier, including: when a SPID user initially establishes a service carrier of the first network, if the redirection function and the inter-frequency handover function are both enabled, the base station sends the SPID user Measurement control command; the service carrier is the carrier; when the different frequency measurement conditions are met, the base station issues a different frequency measurement control command to the user to measure the frequency point used by the second network; the work of the first network and the second network The frequency bands are different and do not share the core network; if the base station does not receive the corresponding measurement report from the user within the preset time, it will be notified to stop the inter-frequency measurement, and the inter-frequency measurement control command will be sent to it periodically until it receives the corresponding measurement report. Receive a measurement report; after receiving the user's inter-frequency measurement report, the base station triggers the user to access the inter-frequency point when it learns that the corresponding inter-frequency point is not connected to the core network of the current service carrier. By applying this application, the requirement of SPID users to access the second network preferentially can be met.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a method and device for selecting a resident carrier. Background technique [0002] At present, there are 1.4G large network and 1.8G communication vehicle network in the private network. Generally, customers require the control ball to be connected to the 1.8G communication vehicle first, that is, when there is 1.8G communication vehicle coverage, it is necessary to trigger the distribution control ball from 1.4G to 1.8 G communication vehicle. [0003] Since the control ball is always in the radio resource control (RRC) connection state, and the communication vehicle and the large network do not share the core network, cross-core network switching is not supported, and the traditional carrier selection scheme based on the frequency priority strategy needs to be carried out through the core network Carrier switching, therefore, the traditional carrier selec...

Problems solved by technology

[0003] Since the control ball is always in the radio resource control (RRC) connection state, and the communication vehicle and the large network do not share the core network, cross-core network switching is not supported, and the traditional carrier selection scheme based on the frequency priority strategy needs to be carried out through the core network Carrier switching, therefore, the traditional carrier selection scheme based on the frequency priority strategy cannot meet the above-mentioned needs for priority access to 1.8G communication vehicles
