Abstract: A system for realizing the reception of a incoming call number by a terminal includes a CDMA network and a HRPD network providing service support for the terminal, respectively, where an MSC in the CDMA network connects with an access network of the HRPD network via interface A1. A method for realizing the reception of a incoming call number by a terminal in advance includes: the MSC in the CDMA network transmitting the incoming call number of a paging to the access network of the HRPD network through interface A1; the access network forwarding the incoming call number of this paging to the called terminal; the called user deciding whether to accept the incoming call based on the received incoming call number. Accordingly, the switching between HRPD and CDMA2000 1x can be avoided when the user decides not to accept the incoming call.

Abstract: An embodiment of the present invention provides a method for implementing load sharing in an overlap area of wireless cellular networks wherein the overlap area of the wireless cellular networks includes at least two networks. The method includes: obtaining load indication information of a network within the overlap area: transmitting the load indication information to a mobile terminal; and selecting a network for residing in or a network to be accessed when initiating a service connection according to the load indication information. Another embodiment of the present invention provides a system for implementing load sharing in an overlap area of wireless cellular networks. According to the embodiments of the present invention, the load between networks in an overlap area may be balanced. Network congestion may be reduced and network resources may be utilized effectively.
