Embodiment

[0122] The specific implementation mode of the present invention provides an embodiment. This embodiment provides a method for inter-system carrier aggregation. This embodiment is as follows Figure 5 It is realized in the aggregated architecture of eHRPD and LTE system as shown, where it should be noted that, the above-mentioned eHRPD can also be replaced by HRPD; the method provided in this embodiment is as follows Figure 6 shown, including:

[0123] S61. The UE has been connected to the LTE system and performs data services;

[0124] S62. The eNB configures the UE to enable the UE to perform inter-system measurement;

[0125] S63. The UE sends the measurement result to the eNB; the measurement result includes: the carrier frequency information of the eHRPD base station, the cell pilot offset, and the signal quality or signal strength of each cell of the eHRPD (eHRPD base station that can be measured) (can be select only one);

[0126] S64. The eNB sends the measurement ...

Abstract

The present invention is applicable to the communication field, and provides a method, device and system for inter-system carrier aggregation. The method includes: when establishing a connection with the first system for data services, receiving the configuration of the base station of the first system, and performing the second System measurement; sending the measurement result of the second system measurement to the base station of the first system so that the base station of the first system forwards the measurement result to the MME; receiving the target carrier information of the second system returned by the MME according to the measurement result; according to the second system The target carrier information is used to establish a connection and bearer with the base station of the second system, and perform data services in the second system. The technical solution provided by the invention has the advantage that the UE can simultaneously perform data services under the two systems.

Description

technical field [0001] The present invention belongs to the communication field, and in particular relates to a method, device and system for inter-system carrier aggregation. Background technique [0002] In order to meet the challenges of wireless broadband technology and maintain the leading edge of the 3rd Generation Partnership Project (3GPP) network, 3GPP formulated the Long Term Evolution (LTE) at the end of 2004. Under the guidance of the evolution plan A new mobile communication network architecture is defined, which only retains the Packet Switched (PS) domain, so this architecture is called Evolved Packet System (EPS) or System Architecture Evolution (SAE) ). [0003] The architecture diagram of the LTE system is shown in figure 1 As shown: Evolved Universal Terrestrial Radio Access Network (E-UTRAN) is the evolved base station eNB, responsible for data modulation and demodulation. The Serving Gateway (S-GW) and the Packet Data Network Gateway (P-GW) are evolve...
